Abstract:

Green Cargo driver idag ett antal terminaler i Sverige i syfte att främja transporter på järnväg och ser möjligheter i att utveckla en av sina terminaler i Göteborg, Göteborg Norra, till en så kallad dry port, alltså en intermodal terminal i inlandet. Detta gav upphov till projektet Terminal Göteborg Norra – en möjlig dry port? med målet att undersöka potentialen och omställningarna med att utveckla befintligt kunderbjudande på Göteborg Norra genom att utreda konceptet dry port samt undersöka efterfrågan på marknaden. Syftet med en dry port är att fungera som en förlängning av hamnen och bör enligt forskare erbjuda samma servicetjänster som en hamn, det vill säga förtullning, säker lagring av både lastade och tomma containrar samt underhåll och städning av containrar. En dry port kan ses som ett bra komplement till hamnar som ligger inne i städer och har problem med begränsade utrymmen i hamnområdet och svårt att expandera då ytan inte längre räcker till. Dessutom kan man minska utsläppen av CO2 genom att få mer gods transporterat på järnvägen. Att utveckla Göteborg Norra, som Green Cargo idag driver i egen regi, skulle innebära att befintliga tjänster behöver kompletteras med de tjänster som fullbordar en dry port. Projektet resulterade i en utredning med potentiella intäkter och kostnader som förväntas uppstå vid ett utvecklande av Göteborg Norra till en dry port. Det visade sig att kostnaderna med att utveckla Göteborg Norra till en dry port är fullt möjliga att tjäna in inom den bestämda tidsramen på två år. Trots det så anser projektet att det finns många delar i utvecklandet som talar emot ett fulländat dry port koncept på Göteborg Norra. Då projektet anser att terminalens läge inte är optimalt för en dry port och att det finns begränsade lagringmöjligheter, oklarheter gällande tulltjänster samt att hamnen inte visar något intresse för att utnyttja tjänsten så är det svårt att motivera omställningen till en fulländad dry port. Däremot finns det en del i dry port konceptet som projektet ser positivt till och det skulle innebära att Göteborg Norra tar emot lastade containrar för transport till hamnen. Då projektets marknadsundersökning visade att många speditörer anser att det är problem med långa köer för att hämta och lämna gods i Göteborgs hamn så skulle Green Cargo kunna erbjuda en tjänst där dessa kunder kan åka till Göteborg Norra och lämna eller hämta sitt gods. Detta under förutsättning att Green Cargo kan erbjuda en billigare lösning och att det inte uppstår köer i trafiken runt terminalen. Klarar Green Cargo detta har de ett bra argument som borde locka både speditörer och Göteborgs hamn att nappa på lösningen.

Abstract:

The issue of congestion along key arteries to maritime terminals, although common around the world, poses a greater problem in Africa, where growth in freight traffic coupled with poor physical and institutional infrastructure affects logistical efficiency and may be detrimental to economic development. As maritime trade increases in such cities, the problem of congestion on arteries to the port becomes a growing issue and research that supports the effective implementation of congestion mitigation measures in the context of the developing countries become crucial. The use of an inland container terminal connected by rail to a port, termed a 'dry port', is one of the measures employed to reduce congestion in developed port cities such as New York/New Jersey, Los Angeles and Sydney. This solution is vital to developing cities as it, by alleviating congestion on roads, improves freight logistics which can help facilitate economic development. Dry port solutions have previously been classified under three main types - close, mid-range and distant - based on the distance of the inland terminal from the port. This thesis aims to quantify the potential road network benefits of diverting containers to a close dry port located at the rim of a developing port city. It does this by exploring the impact of a single close dry port with varying operational characteristics. These operational characteristics (variables) relate to the container allocation patterns employed and the provision of an Empty Depot Service (EDS) and a Freight Distribution Service (FDS) within the facility. The case of Lagos, Nigeria, is selected for study as it is a developing port city where an increase in freight volume, the location of ports within close proximity to major GDP generators, coupled with poor physical and institutional infrastructure affect logistical efficiency. The research involves developing a container freight traffic model for Nigeria to simulate the current patterns of containerised cargo traffic flows (the reference scenario) as well as that which arises from the introduction of the close dry port solutions (test scenarios). Within this model, the World Bank's HDM IV vehicle operation cost functions are integrated to capture factors that influence freight routing choice in developing countries like Nigeria. The network impact of the containerised cargo traffic patterns derived from the reference and test case scenarios is the output of this model and is measured as the total container-related freight vehicle-km and vehicle-hrs in the road network. This impact is measured for routes to and from the seaports, routes to and from zones in the port city and for the whole system. The output of the test scenario cases are compared to those from the reference case to obtain the relative network benefit of each test scenario. The relative benefits of the dry port with varying characteristics are then compared to obtain results from which the main conclusion are drawn. It is found that a dry port solution with an FDS can provide a container-related freight vehicle-km and vehicle-hrs savings of up to 52% more that a dry port solution without an FDS. On the other hand, the benefit of a dry port solution is found to be significantly less sensitive to the empty depot service variable. Furthermore, the network benefit of a dry port solution is found to be sensitive to the container allocation patterns employed. The close dry port is found to present up to 40% higher benefits by serving only zones closer to the dry port than the seaport. However, the results show that the benefit of the dry port varies depending on the part of the network being accessed. For example, the dry ports with an FDS are shown to provide savings of up to 20% to the system (routes to and from all zones in the country) and up to 39% on routes to and from the port city. However, much higher benefits of up to 78% are observed on routes to and from the seaport. In general, it is found that the network benefit of the close dry port increases almost linearly with increase in dry port usage by up to 80% depending on the services provided within the facility, the container allocation methods employed and the parts of the road network being accessed. The findings contribute to the literature on the impact of dry port characteristics on the efficiency of road networks in developing port cities and can be used to formulate transport policies that address issues of traffic congestion. They present policy makers with insight into the requirements for a dry port solution located at the rim of a port city to reduce congestion and improve the efficiency of the road network. Furthermore, the research highlights some factors which influence freight routing decisions in developing countries that are not normally taken into account in urban freight models and discusses ways of dealing with them. The modelling framework employed shows how it is possible to integrate freight supply chain modelling into urban transport models. The model developed in the thesis can form part of a cost-benefit analysis of individual dry port solutions centred on mitigating congestion in port cities.

Abstract:

Globalization of the world’s economy, containerization, intermodalism and specialization have reshaped transport systems and the industries that are considered crucial for the international distribution of goods such as the port industry. Simultaneously, economies of location, economies of scope, economies of scale, optimization of production factors, and clustering of industries have triggered port regionalization and inland integration of port services especially those provided by container terminals. In this integration dry ports have emerged as a vital intermodal platform for the effective and efficient distribution of containerized cargo. Dry ports have enabled port and hinterland expansion increasing the competitiveness of container terminals at seaports. In consequence, container terminals and dry ports are establishing formal and informal relationships to strengthen the competitiveness of their hinterlands and to improve their role in the physical distribution of goods. This study assesses the characteristics of relationships between container terminals and dry ports. Such assessment is conducted based on a set of relationship characteristics proposed in a relationship assessment model for customer/supplier, in which dry ports are given the role of suppliers of port services to container terminals. In addition, the research assesses the impact of the relationships between container terminals and dry ports on inter-port competition. The main findings of the research led to conclude relationships between container terminals and dry ports are characterized by medium mutuality, low particularity, low co-operation, low conflict, low intensity, low interpersonal inconsistency, high power/dependence and medium trust. Additionally, it was concluded that such relationship characteristics impact inter-port competition in two main ways. In one hand by driving container terminals to maximize the utilization of dry port’s capabilities such as container transport/delivery, container storage, customs clearance, information systems and intermodal connections to industrial clusters. On the other hand, by constructing channels of interaction through which dry port’s benefits for hinterlands such as increase of container terminal capacity, reduction of road congestion, increase of modal shift and hinterland expansion are used as leverage in competition for containerized cargo.

ENGLISH ABSTRACT: Currently maritime ports, including the Port of Cape Town, experience congestion, pollution and other logistics-related problems due to increasing levels of container traffic. The presence of these problems has caused port planners, port operators and logistics firms to look for new solutions in this transport sector. The dry port concept, whereby offloaded containers are stored outside the maritime port in a dedicated logistics area, is recognized as a means for solving some of these major problems, thereby promoting economic development and logistics integration as well as reducing the demand on limited capacity (land and access) at the maritime port. Therefore, the core objective of this study is to demonstrate that the implementation of the dry port concept is a feasible alternative for expanding the throughput capacity of the Cape Town Container Terminal. The Port of Cape Town is strategically one of the best placed ports in South Africa as it is positioned at the South Western extremity of the continent of Africa, thereby linking America and Europe with Asia, the Far East and Australia. Furthermore, the Port of Cape Town also forms a direct link between international trade and about three (3) million consumers in the Western Cape. The recent expansion of the Cape Town Container Terminal was a major investment which included the upgrading of equipment and the expansion of workable surface area, thereby increasing the container terminal yard capacity to 1.4million TEU (TEU = Twenty foot Equivalent Unit) per annum. However, this report showed that the abovementioned increase in volumes as well as the resulting congestion continues to be a challenge at the Port of Cape Town. Firstly, the predicted future container volumes show that the demand in the Port of Cape Town could reach between 1.9 million and 3.2 million TEU per annum by 2039. Secondly, the evaluation of the operational and infrastructural characteristics of the existing Cape Town Container Terminal demonstrated that container terminal yard (CY) area is the capacity limiting characteristic of the terminal and that the operational and infrastructural limits could be reached between 2018 and 2026. The two main functions of a dry port in the Western Cape transportation network would be international trade processing and congestion relief, which are achieved through the duplication and supplementation of the Cape Town Container Terminal facilities at an inland location. The dry port would allow the Western Cape supply chain to absorb any future container volume demands that exceed the CY capacity of the Port of Cape Town and could potentially attract an annual throughput of 0.7 million TEU by 2039. Furthermore, the facility could address the problem of congestion in and around the greater Cape Town metropolitan, resulting in an improved transportation network that will have a positive effect on passenger traffic, productivity of trucks, competitiveness of the Port of Cape Town as well as the environmental sustainability of the transportation system. The dry port concept would therefore be appealing to Transnet Port Authority / Transnet Port Terminals, Shippers and Logistics Managers and the Western Cape Regional Community. The site selection analysis performed in this study evaluated three possible dry port locations, namely: Kraaifontein Area, Ysterplaat Air Force Base and Bellville Precinct. Although the analysis identified that all three of the sites have the potential to be developed into a successful dry port; however, that the Bellville Precinct is the preferred location due to the presence of the Belcon freight rail facility. The success of such a facility will greatly depend on the project’s ability to ensure that the resources needed for the initial investment is kept to a minimum, and ultimately the most viable dry port solution in the Western Cape region would be the phased development of Bellville Precinct. From this it is clear that a dry port could be a feasible alternative for expanding the throughput capacity of the Port of Cape Town, as well as improving the transport infrastructure in the Cape Town area.
AFRIKAANSE OPSOMMING: Maritieme hawens, insluitende die Kaapstadse hawe, ondervinding tans opeenhoping, besoedeling en ander logistieke probleme as gevolg van toenemende vlakke van die houer verkeer. Die teenwoordigheid van hierdie probleme het veroorsaak dat hawe beplanners, hawe-operateurs en logistiek maatskappye op soek is vir nuwe oplossings in die vervoer sektor. Die droë hawe konsep word erken as 'n middel vir die oplossing van sommige van hierdie probleme, en sodoende ekonomiese ontwikkeling en logistieke integrasie te bevorder, sowel as die verlaging van aanvraag op beperkte kapasiteit (grond en toegang) by die maritieme hawe. Daarom is die kern doel van hierdie studie om aan te toon dat die implementering van die droë hawe konsep 'n haalbare alternatief is vir die uitbreiding van die deurset kapasiteit van die Kaapstadse Houerterminaal. Die Kaapstadse hawe is strategies een van die bes geplaaste hawens in Suid-Afrika, want dit is geleë aan die suid-westerlikste punt van Afrika en verbind Amerika en Europa met Asië, die Verre Ooste en Australië. Verder vorm die Kaapstadse hawe ook 'n direkte skakel tussen die buitelandse markte en die drie (3) miljoen verbruikers in die Wes-Kaap. Die onlangse uitbreiding van die Kaapstadse Houerterminaal het die stoorkapasiteit van die terminaal aansienlik verbeter an 1.4 miljoen TEU per jaar, deur middel van die opgradering van toerusting en die uitbreiding van werkbare oppervlak. Hierdie verslag bewys egter dat die bogenoemde toename in volumes sowel as die gevolglike opeenhoping steeds teenwoordig is in die Kaapstadse hawe. Eerstens, die voorspelde toekomstige houervolumes toon dat die aanvraag in die Kaapstadse hawe tussen 1.9 miljoen en 3.2 miljoen TEU's per jaar kan bereik teen 2039. Tweedens, die evaluering van die operasionele en infrastrukturele kenmerke van die bestaande Kaapstadse Houerterminaal het getoon dat die houer stoorarea die kapasiteit beperkende kenmerk van die terminaal is en dat die operasionele en infrastrukturele perke moontlik tussen 2018 en 2026 bereik kan word. Die twee hoof funksies van 'n droë hawe in die Wes-Kaap vervoer netwerk sal internasionale handel verwerking en opeenhoping verligting wees. Hierdie funksies sal bereik word deur die duplisering en aanvulling van die Kaapstadse Houerterminaal fasiliteite by 'n binnelandse perseel. Die droë hawe sal toelaat dat die Wes-Kaap verskaffersiklus enige toekomstige houervolumes, wat meer is as die houer stoorarea kapasiteit van die Kaapstadse hawe, te kan hanteer en kan potensieel 'n jaarlikse deurset van 0.7 miljoen TEU hanteer.

Abstract:

The movement of passengers, goods, and information has always been fundamental components of human societies. It is all related to transport costs as well as to the attributes of what is being transported. However, regulations, laws, and tariffs can influence transportability. Countries around the world have been changing their international trade policies by reducing both tariff and non-tariff barriers. Informal barriers hinder trade and the benefits of export, such as economic growth, that come with the achievement of trade liberalisation. It was found that the impact of transport costs on trade patterns has become an important study. Theoretical and empirical work in international trade only recently began considering the geography of exports as a possible explanation for high transport costs. For instance, factors such as distance, market size, scale economies, and agglomeration affect transportation costs around the world. Transport costs in South Africa are a relevant issue due to its geographical position. South Africa is situated far from its major trading partners. In addition, the majority of South African exports originate in Gauteng, which is around 600km from the nearest seaport. For South African exports to remain competitive, domestic transport costs must be reduced. One method of cutting costs is by connecting a container dry port with an intermodal transport system to the major seaports (namely Durban, Port Elizabeth, and Cape Town). The empirical study was conducted in the form an interview-based questionnaire. A total of 18 questions were asked to individuals at a terminal in Gauteng. The purpose of the questionnaire was to gather information on the service delivery of South African inland terminals. This led to the conclusion that City Deep functions well in terms of service delivery and provides extra services to both exporters and importers. Potential problems regarding City Deep's infrastructure were identified. It was found that train and truck congestion within City Deep is an everyday phenomenon. The existing infrastructure cannot handle the train and truck traffic entering City Deep. It was found that clients prefer road transportation to rail transportation, therefore, the amount of trucks entering and leaving City Deep causes congestion. This not only affects the infrastructure at City Deep, but also that of South Africa. More trucks on the roads exacerbate air pollution and road accidents, and overloaded trucks damage South African roads.

An important element in the transport and logistics infrastructure of international multimodal transport is the seaport. However, today, due to the growth of international trade, many ports no longer have time to cope with their functions. The main reason for this is the congestion of terminals and lack of free space for receiving goods. Even the use of modern technologies of cargo handling and logistics management does not solve this problem. Therefore, the question arises about finding free territories and creating new terminals on them, the so-called “dry ports”.
Важливим елементом транспортної та логістичної інфраструктури міжнародних мультимодальних перевезень є морський порт. Однак сьогодні, завдяки зростанню міжнародної торгівлі, багато портів вже не встигають справлятися зі своїми функціями. Основна причина цього - скупченість терміналів і відсутність вільного місця для прийому товарів. Навіть використання сучасних технологій обробки вантажів та управління логістикою не вирішує цієї проблеми. Тому виникає питання про пошук вільних територій та створення на них нових терміналів, так званих «сухих портів».

Abstract:

Depuis la prolifération des bases de données partiellement étiquetées, l'apprentissage automatique a connu un développement important dans le mode semi-supervisé. Cette tendance est due à la difficulté de l'étiquetage des données d'une part et au coût induit de cet étiquetage quand il est possible, d'autre part.L'apprentissage semi-supervisé consiste en général à modéliser une fonction statistique à partir de base de données regroupant à la fois des exemples étiquetés et d'autres non-étiquetés. Pour aborder une telle problématique, deux familles d'approches existent : celles basées sur la propagation de la supervision en vue de la classification supervisée et celles basées sur les contraintes en vue du clustering (non-supervisé). Nous nous intéressons ici à la deuxième famille avec une difficulté particulière. Il s'agit d'apprendre à partir de données avec une partie étiquetée relativement très réduite par rapport à la partie non-étiquetée.Dans cette thèse, nous nous intéressons à l'optimisation des bases de données statistiques en vue de l'amélioration des modèles d'apprentissage. Cette optimisation peut être horizontale et/ou verticale. La première définit la sélection d'instances et la deuxième définit la tâche de la sélection de variables.Les deux taches sont habituellement étudiées de manière indépendante avec une série de travaux considérable dans la littérature. Nous proposons ici de les étudier dans un cadre simultané, ce qui définit la thématique de la co-sélection. Pour ce faire, nous proposons deux cadres unifiés considérant à la fois la partie étiquetée des données et leur partie non-étiquetée. Le premier cadre est basé sur un clustering pondéré sous contraintes et le deuxième sur la préservation de similarités entre les données. Les deux approches consistent à qualifier les instances et les variables pour en sélectionner les plus pertinentes de manière simultanée.Enfin, nous présentons une série d'études empiriques sur des données publiques connues de la littérature pour valider les approches proposées et les comparer avec d'autres approches connues dans la littérature. De plus, une validation expérimentale est fournie sur un problème réel, concernant le diagnostic de transport ferroviaire de l'état de la Thaïlande
We are drowning in massive data but starved for knowledge retrieval. It is well known through the dimensionality tradeoff that more data increase informative but pay a price in computational complexity, which has to be made up in some way. When the labeled sample size is too little to bring sufficient information about the target concept, supervised learning fail with this serious challenge. Unsupervised learning can be an alternative in this problem. However, as these algorithms ignore label information, important hints from labeled data are left out and this will generally downgrades the performance of unsupervised learning algorithms. Using both labeled and unlabeled data is expected to better procedure in semi-supervised learning, which is more adapted for large domain applications when labels are hardly and costly to obtain. In addition, when data are large, feature selection and instance selection are two important dual operations for removing irrelevant information. Both of tasks with semisupervised learning are different challenges for machine learning and data mining communities for data dimensionality reduction and knowledge retrieval. In this thesis, we focus on co-selection of instances and features in the context of semi-supervised learning. In this context, co-selection becomes a more challenging problem as the data contains labeled and unlabeled examples sampled from the same population. To do such semi-supervised coselection, we propose two unified frameworks, which efficiently integrate labeled and unlabeled parts into the co-selection process. The first framework is based on weighting constrained clustering and the second one is based on similarity preserving selection. Both approaches evaluate the usefulness of features and instances in order to select the most relevant ones, simultaneously. Finally, we present a variety of empirical studies over high-dimensional data sets, which are well-known in the literature. The results are promising and prove the efficiency and effectiveness of the proposed approaches. In addition, the developed methods are validated on a real world application, over data provided by the State Railway of Thailand (SRT). The purpose is to propose the application models from our methodological contributions to diagnose the performance of rail dry port systems. First, we present the results of some ensemble methods applied on a first data set, which is fully labeled. Second, we show how can our co-selection approaches improve the performance of learning algorithms over partially labeled data provided by SRT

Abstract:

Container terminal capacity is a crucial issue for port and terminal operators nowadays as it is one of the key points for their success and increasing their competitive market position in the maritime industry. Therefore, researchers have tried to find solutions for the over capacity problem that faces many terminal operators. This research suggests dry ports as one of the most suitable solution for this problem through proposing a structured framework to adopt the right policy decisions for Dry Port location and capacity. To achieve the presented framework some areas were addressed in detail to have the full picture clear. The current status of the global container sector was assessed, also, the main capacity problems of container terminals with a view to reviewing the suggested solutions was investigated, hence the need for dry ports. In addition, policies for providing optimal location and capacity decisions for container terminals were identified. A technique that supports assessing container terminal location and capacity policy decisions with particular reference to dry ports were developed. Moreover, a case study on Alexandria International Container Terminal for validating the results was conducted. The current research was facilitated by experts from the maritime transport industry, through the application of the Delphi Technique. Applying such a technique enables collaborating experts to share experience modify statements and re-asking to reach a final exact answer that could be generalized. The consensus achieved will help build knowledge and understanding of potential Dry Ports’ policies of the maritime transport sector. This research seeks to make an original contribution to knowledge by developing a structured framework to identify policy decisions for location and capacity of Dry Ports using a Delphi technique as a support tool for terminal managers and operators, port planners, policy makers, and investors in deciding decisions relevant to Dry Port investment.

Abstract:

Problem: Due to several changes in the market, economy, industry and the environment there was an increasing trend in emerging dry ports/inland terminals throughout Sweden. A dry port is still a young term in the transportation field gaining more popularity and attention. The gap in literature was found that the dynamics of dry port evolution is not yet explored. Thus, the development of the layout, services offered and involved actors of dry ports in Småland, Sweden have to be studied. Purpose: The purpose for this report seeks to reveal how dry ports have evolved from establishment, in the area around Jönköping, and to discover in what form the dry ports can operate and compete. The study was based on the dynamics of three elements: layout, value added services and networks. Theory: In the theoretical research the dry port concept is described. Due to the variety of descriptions, authors formed a definition for the thesis to clarify the content. Further, the literature analysis contained the characteristics, classifications and reasons of development as well as involved actors, advantages and disadvantages, location, layout, design and performance measurements. Method: The case study method was chosen to cover the identified gap. This qualitative study with semi-structured interviews conducted face-to-face and by telephone was accomplished with fourteen experts. If the authors faced problems regarding phone interviewees, open questions were prepared and sent to the respondent via email. The data gathering phase was followed by the analysis after which the conclusions were drawn. Conclusion: The thesis proves that the development of dry ports is affected by a large number of internal and external factors. Terminals need to execute a thorough analysis of the market and the location in which they plan to operate. Therefore, the market has to be analysed continuously in order to keep improving their networks and value added services. Furthermore, the layout has to be adjusted for the changes and measurements have to be performed in order to increase the efficiency.

Abstract:

This study aims to explore effectiveness within intermodal transportation of semi-trailers based on the variables cost and time. Intermodal transport can be explained as a transportation of a carrier, from the origin to the final destination, using two or more modes of transport (Crainic & Kim, 2007 p.467). This study focuses on the two modes of transport rail and road. The rail transportation has big advantages towards other modes of transport since it has less impact on the environment, given that the energy is produced in Sweden (Trafikverket 2017) but there are more benefits to be utilized. The rail transportation is generally more profitable on distances greater than 500 km, thus it can transport high volumes of goods over long distances for a low cost. The fixed costs that´s added in the terminals and the rail transports low degree of flexibility compared to the road transport is the primary reasons why rail transportation isn´t profitable on shorter distances. This study has made a market research to see where the final destinations for the imported semi-trailers are located in Sweden and Norway. This, to see where there are potential to develop and create new rail shuttles from Port of Gothenburg to dry ports across the Swedish and Norwegian inland for transportation of semi-trailers. Interviews have been conducted with carriers to create a more correct view of the current situation. Study results show that the greatest volumes of the transported semi-trailers ends up in the areas around Helsingborg and Stockholm, with the region around Gothenburg excluded. Dry ports positioned in this area show the best potential for development of new rail shuttles. The results from conducted interviews with carriers express that time is the most important aspect for their operation and their clients, that is also the reason why they don´t use the railway for transportation of semi-trailers. Carriers also consider the trains to be unreliable and the railway operation in Port of Gothenburg has so far not been operating well enough for them. The result show that 38 percent of the imported semi-trailers have their final destination in the area around Gothenburg and naturally it´s not possible for the railway to compete with the road transport at such a short distance. In order for the railway to compete with the road transport, rail shuttles to regions with high flows of semi-trailers must be developed to not loose in time and flexibility. Thus, the railway transportation has other opportunities than just transportation. In dry ports there are opportunities for storage of goods, which is generally cheaper than in the port and simultaneously create time gains in the final transportation, thus the goods are closer to the customer. Port of Gothenburg can compete with other ports, which are geographically closer to a certain customer, through more rail shuttles with more frequent departures and then take more market shares within Nordic transportation.
Studien syftar till att undersöka transporteffektiviteten för intermodala transporter av semitrailrar med utgångspunkt från variablerna kostnad och tid. Intermodala transporter kan förklaras som en transport av en lastbärare från dess ursprung till dess slutdestination med hjälp av två eller flera olika transportsätt (Crainic & Kim, 2007 s.467) och denna studie fokuserar på de två transportsätten järnväg och väg. Just järnvägstransporten har en stor fördel gentemot andra transportsätt då det är ett mer miljövänligt alternativ, förutsatt att det är eldrivna tåg samt att elen är producerad i Sverige (Trafikverket 2017) men det finns även fler fördelar som kan utnyttjas. Järnvägstransporten är generellt lönsammare på avstånd längre än 500 km, då det kan transportera stora volymer över långa avstånd till en låg kostnad. Varför det inte är lönsamt på kortare sträckor beror framför allt på de fasta avgifter som tillkommer vid terminalerna och järnvägens relativt låga flexibilitet gentemot vägtransporten. Studien har gjort en marknadsundersökning för att se var de importerade semitrailrarna har sin slutdestination inom Sverige och Norge. Det för att se var det finns potential för att utveckla och skapa nya järnvägspendlar från Göteborgs Hamn till torrhamnar för transport av semitrailrar via järnväg. Intervjuer har utförts med speditörer i anslutning till hamnen för att skapa en så bra bild som möjligt av nuläget. Resultatet visar att de största volymerna i flödet av semitrailrar går till Helsingborg och Stockholm med omnejd, med Göteborg exkluderat. Det är de två områdena som visar potential för att eventuellt skapa järnvägspendlar till torrhamnar. Vid intervjuerna som utförts uttrycker speditörerna att tid är den viktigaste aspekten för deras verksamhet och kunder. Det är även anledningen till att de inte använder sig av järnvägstransport för semitrailrar, då tågen är för opålitliga och verksamheten för järnvägstransport kring Göteborgs Hamn inte har fungerat för dem hitintills. Resultatet visar även att drygt 38 procent av de importerade semitrailrarna har sin slutdestination i Göteborgsområdet och där kan naturligtvis inte järnvägstransporten konkurrera med vägtransporten på grund av det korta avståndet. För att järnvägstransporten ska kunna konkurrera med vägtransporten måste det skapas pendlar till de regionerna med större flöden för att inte förlora tid och flexibilitet gentemot vägtransporten. Dock så ger järnvägstransporten andra möjligheter än bara transport av gods. I torrhamnarna finns möjligheter för lagring av gods, som generellt är billigare än lagring i hamnen och ger samtidigt tidsvinster när den slutliga transporten till kund ska utföras, då godset är närmare kunden. Göteborgs Hamn kan konkurrera med andra hamnar som geografisk ligger närmare en viss kund, genom att fler järnvägspendlar med frekventare avgångar kan skapas och på så sätt ta marknadsandelar inom nordisk transport.

Abstract:

Hållbarhet har blivit ett aktuellt ämne inom de flesta verksamheter och strävan är erhålla en ekonomisk vinning utan att äventyra naturresurser, människan och samhället. Verksamheters förmåga att distribuera gods säkert, snabbt och kostnadseffektivt är avgörande för internationell och inrikes handel och ekonomisk utveckling. Godstransporter är en stor källa till utsläpp av växthusgaser och därför är det viktigt att nya transportlösningar hittas för att minska de avtryck som godstransporter gör i en försörjningskedja. Användningen av så kallade högkapacitetsfordon, HCT-fordon, förväntas öka då möjligheten att köra lastbilar som överskrider EU:s dimensioner för längd, bredd och vikt kan medföra ökad effektivitet och reducerad miljöpåverkan. Även konceptet torrhamnar, det vill säga en anläggning med en terminal som drivs likt en hamn, kan användas för att konsolidera gods, avlasta hamnen och öka intermodaliteten hos godset. Intermodalitet innebär att godset fraktas från A till B med hjälp av en kombination av flera olika typer av fraktsätt, exempelvis sjö, tåg och lastbil. Följande rapport kartlägger hur en samverkan mellan högkapacitetsfordon och torrhamnar skulle kunna se ut. Detta genomförs med hjälp av att utifrån hållbarhetsmodellen triple bottom line som avser de tre dimensionerna ekonomi-, miljö- och sociala effekter, identifiera styrkor och svagheter hos begreppen. Med hjälp en teoretisk litteraturstudie, en fallstudie av ETT-projektet, en observation av Skaraborg Logistics Center samt nio stycken intervjuer med experter inom området, analyseras effekterna av en samverkan mellan högkapacitetsfordon och torrhamnar. Rapporten identifierar att bättre ekonomiska-, miljömässiga och sociala effekter nås om en torrhamn är kopplad till ursprungshamnen med järnväg snarare än med HCT-fordon. Ytterligare identifierad problematik där en torrhamn försörjs med HCT-fordon utgörs av de tillfälliga tillstånden för att få framföra de längre och tyngre lastbärarna. Analysen visar att för att uppnå en god effekt från en samverkan mellan HCT-fordon och torrhamnar krävs att varje begrepp ensamt uppnår de faktorer som krävs för god effekt. Rapporten är avgränsad till att räkna allt gods som normalt gods, endast avse HCTtransporter på väg samt att förutsätta att svenska arbetsregler följs vid inrikes transporter på väg. Rapporten studerar inte detaljer kring potentiell utveckling inom tekniken, exempelvis säkerhetssystem, IT-system eller aerodynamik.
Sustainability has become a highly prioritized subject among most companies and the goal is to maintain financial value without jeopardizing nature's resources, neither human health nor the society. How safe, fast and cost efficient a company distribute their goods is crucial for international- and domestic trade as well as economic growth. Haulage is a great source of greenhouse gas emissions and therefore it is crucial that new solutions of transport are developed in order to reduce the negative footprint of haulage in a supply chain. The use of high capacity transporting (HCT) vehicles is assumed increase when the EU's dimensions for a truck’s length, width and weight are allowed. This exception from EN standards would lead to increased transport efficiency, economic efficiency and reduced impact on the environment. The logistical solution of dry ports, namely a port on inland, can be used to consolidate goods, unburden the port and increase intermodality within the goods. Intermodality is when goods is transported between its starting location to its end location using several different kinds of transport ways. The following report maps how a synergy between high capacity vehicles and dry ports would look like. By using the triple bottom line sustainability model the report identifies strengths and weaknesses of the two concepts. The reports analysis is created from a theoretical literature study, a case study of the ETT project, an observation of Skaraborg Logistics Center and nine interviews with experts within the field. The report identifies that better economic, environmental and social effects are achieved if a dry port is connected to the port of origin by rail way rather than with HCT vehicles. Further identified problems is the temporary permit of conveying the longer and heavier vehicles. The analysis shows that in order to achieve a good effect from an interaction between HCT vehicles and dry ports, each term alone require that the necessary factors for good effect is fulfilled. The reports limitations are to consider all goods being normal gods and only to consider HCT-vehicles, not HCT-haulage by rail way. The writers also make the assumption that Swedish rules of labor are applied on domestic transportations by road. The report does not study details within IT, security systems nor aerodynamic.

Abstract:

In today´s society large quantities of goods are shipped both domestic in Sweden as well as across borders. The increasing flow of goods require higher demands on the capacity of the infrastructure and at the same time think and act for a sustainable environment. The overall aim of the study is to highlight development areas for cargo freight by railway. The more specific goals of the study is to identify what enablers that is needed when to establish an intermodal terminal that will handle break-bulk cargo directly from railway, and what barriers that might be. To achieve the aim and goal a qualitative study was conducted with interviews as primal data. Studying the market prerequisites and conducting a competitive intelligence and a benchmark conducted the result. In the result, the interviews and the examined documents has ben compiled, these data has been the basis for the analysis and conclusion. Large parts of the collected data indicated that break bulk cargo handling in intermodal terminals is currently something that is not offered and it is not considered to be economically viable. However, the study also revealed that break bulk cargo handling is a desired service from the business sector as it is regarded as an environmentally friendly mode of transportation, something that the business sector appreciate. To cope with this kind of cargo handling and transportation more research is needed, better cooperation between the private- and the public sector as well as infrastructure changes.
Idag fraktas stora mängder gods både inom Sverige och över landsgränserna. Det ökande godsflödet ställer högre krav på infrastrukturens kapacitet samtidigt som det blir allt viktigare med transporter som är hållbara ur miljösynpunkt. Studiens övergripande syfte är att belysa utvecklingsmöjligheter av godstransport på järnväg. Mer specifika mål för studien är att identifiera vilka förutsättningar som bör finnas vid etablering av kombiterminal med styckegodshantering direkt från räls samt vilka barriärer det finns mot det. För att uppnå undersökningens syfte och mål genomfördes en kvalitativ studie med intervjuer som primärdata. Genom att studera marknadsförutsättningar, genomföra en omvärldsbevakning och en benchmark utformades resultatet. I resultatet har intervjuerna tillsammans med den granskade dokumentationen sammanställts, dessa data har sedan legat som grund till analysen och slutsatsen. Stora delar av insamlade data pekade mot att styckegodshantering på kombiterminal i dagens läge inte är något som erbjuds samt att det inte anses vara ekonomiskt hållbart att hantera styckegods på kombiterminal. Dock visade undersökningen att styckegodshantering på kombiterminal är en önskad tjänst från näringslivet då det anses vara ett miljövänligt transportsätt för gods, något som näringslivet värdesätter. För att klara av denna typ av hantering och transport krävs mer forskning, bättre samarbete mellan den privata och offentliga sektorn samt infrastrukturella förändringar.

Abstract:

O comércio internacional é uma atividade imprescindível que impacta diretamente a balança comercial e, por extensão, a capacidade de crescimento dos países. O comércio exterior brasileiro não foge à regra e precisa de todas as inovações e implementações possíveis de forma a contribuir para aumentar a competitividade do Brasil no mundo globalizado e inseri-lo definitivamente no cenário econômico internacional. Os Portos Secos - antigos Eadis - são uma ferramenta logística inserida neste contexto podendo desempenhar um papel vital no comércio exterior. São uma opção para o gargalo em portos e aeroportos, para a armazenagem entrepostada para importadores e exportadores, além de uma saída de industrialização alfandegada para pequenas e médias empresas. A utilização de portos secos é uma realidade em países que hoje estão na ponta do comércio internacional. Nesta dissertação serão apresentados o que são os portos secos do Brasil, as legislações que os regem, vantagens na sua utilização, evolução dos serviços oferecidos na conjuntura atual e os principais problemas enfrentados e que impactam na sua atuação mais efetiva como hub service. A partir da síntese das informações obtidas, avaliamos como estão estruturados os portos secos no Brasil, seu nível de profissionalização e tecnologias empregadas.
The international trade is directly connected with the trade balance as well the capacity of commercial growth for each country. The same consideration is quite valid for Brazilian foreign trade that needs all of the innovations and new implementations in order to raise its competitiveness and, definitively, to insert Brazil into the economics international context. Known as Eadis in the past, the dry ports are a valid logistics alternative in the foreign trade context. Also, they are able to act as a smart key for Importers and Exporters. They are an option for some Brazilian logistics problems such as the follows: cleaning the bottleneck in the operation of ports and airports because they function as a customs warehousing; and, the option for smaller and medium size companies to use them as an industrial environment for custom production activities. Around the world, the dry ports have been used by countries operating at a top level in the international trade market. This dissertation will give information about the Brazilian dry ports, the laws involved in their functioning, the advantages of their utilization, the evolution of their services and the main problems impacting their performance as a hub service. In connection with all the information collected, an analysis is presented covering the structure of the dry ports, their professional level and the technologies applied.

Abstract:

Este trabalho mostra os resultados obtidos durante as atividades de pesquisa e levantamento de dados sobre os equipamentos urbanos de carga denominados Estações Aduaneiras Interiores (EADIs), conhecidos como Portos Secos, na identificação de impactos ambientais resultantes das operações portuárias desses estabelecimentos. O conflito na utilização do espaço viário da área urbana por modos e sistemas de transporte de carga, incumbidos da tarefa de movimentação e transporte de mercadorias dos Portos Secos nas cidades brasileiras, especialmente aquelas de maior porte e em regiões metropolitanas, a saber, caminhões e trens, leva à preocupação tanto pela inexistência de uma legislação específica locacional para estes equipamentos impactantes, como pela grande disseminação destes empreendimentos, especialmente na década de 1990. Aspectos operacionais como a movimentação de cargas e intermodalidade de transportes nas áreas dos Portos Secos, as atividades produtivas urbanas e regionais e a utilização dos Portos Secos, a concentração desses equipamentos nas periferias industriais urbanas das maiores cidades do país, a utilização do sistema viário principal urbano para a viabilização do transporte de cargas, a localização dos Portos Secos e a logística empresarial, entre outros, chamam a atenção num contexto onde o transporte de cargas e o cumprimento das leis geradas pelas políticas governamentais e de regulamentação ainda não reconhecem as necessidades reais das cargas urbanas no Brasil. Aspectos de planejamento para os projetos dos Portos Secos e a atenção à circulação de cargas no ambiente urbano, frente ao uso e ocupação do solo, determinados pelas leis municipais e à infra-estrutura urbana existente, calcados exclusivamente nos custos operacionais e na acessibilidade, subsidiam este trabalho na formulação de diretrizes de planejamento estratégico de uso e ocupação do solo urbano para Portos Secos, para a redução dos impactos ambientais negativos dos transportes urbanos de cargas. Os principais impactos ambientais, que afetam (de forma mais aguda) a área urbana que hospeda o Porto Seco, especialmente nos casos onde não há um estudo de pré-viabilidade e compatibilização do equipamento ao uso e a ocupação do solo, bem como sua adequação às regras do Planejamento Urbano relacionado ao Planejamento dos Transportes tanto nos ambientes físico, natural, político, legal e de planejamento quanto no ambiente sócio-econômico. Examinar o funcionamento de um Porto Seco - EADI Ribeirão Preto - e sua relação impactante na área urbana onde atua, sua movimentação de cargas e prestação de serviços, levando em conta os custos econômicos diretos e indiretos para diferentes atividades, especialmente os custos e impactos ligados aos ambientes natural, social e econômico, faz parte de um diagnóstico a ser elaborado a partir de indicadores de qualidade de funcionamento da área urbana. Os problemas da localização dos Portos Secos induzem a formulação de diretrizes de planejamento estratégico de uso e ocupação do solo que auxiliem na minimização dos impactos ambientais causados durante a realização das tarefas de armazenamento, manuseio, distribuição e transporte de cargas. Os resultados aqui apresentados poderão ser de grande pertinência e utilidade para o poder público na formulação de um quadro legal e de regulamentação e para o segmento empresarial ansioso por melhores decisões estratégicas. Este trabalho apresentará dados, imagens, mapas, tabelas, gráficos, entre outros, tornando-se mais dinâmico na leitura e compreensível no aporte teórico.
The present work brings forth the results of the research and data colleting activities on the freight urban equipment called Interior Custom Stations (ICSs), named EADI in portuguese, also known as Dry Ports, in the identification of the impact the operations carried out in these stations may have on the environment. The problematic use of the urban locomotion spaces by trucks and trains, the modes and systems of freight transportation in charge of moving and transporting freight from the Dry Ports to Brazilian cities, especially the larger and metropolitan ones, in troublesome for the lack of specific local legislation for such impact equipments as well as for their spread in Brazil specially in the 1990th decade. Operational aspects like freight moving and transport intermodality in the Dry Port areas, productive urban and rural activities and the Dry Ports usage, the concentration of these equipments in country\'s larges cities urban industrial outskirts, the location of the Dry Ports and business logistics, among others, call our attention in a context where freight transporting and the fulfillment of the laws created by government and regulation policies still do not understand the real needs of urban freight in Brazil. Planning aspects of the Dry Ports\' Projects together with the attention to the circulation of freight in urban surroundings in face of both use and occupation of the land determined by Municipal laws and the existing urban infra-structure (based exclusively on operational costs and accessibility), support this research in the formulation of strategic planning guidelines of use and occupation of urban land for Dry Ports towards the reduction of negative environmental impacts of urban freight transporting. The major environmental impacts affect (in a more direct way) the urban area that houses the Dry Port, most visibly in cases when there are no studies on the pre-viability and compatibility of the equipment to the use and occupation of the land, as well to its adequacy to the rules of Urban Planning concerning Transport Planning in the physical, natural, political, legal and socio-economical ambience. A close examination of a Dry Port - EADI Ribeirão Preto -, its important relation to the urban area where it is placed, the moving of freight and services offered there taking into account the direct and indirect economic costs for different activities, above all the costs and impacts related to the natural, social and economic ambience, is a part of a diagnosis to be elaborated from the urban functioning quality indicators. The problems in the Dry Ports location lead to the formulation of strategic planning guidelines for the use and occupation of land, which may help minimize environmental impact from storing, handling, distribution and transportation activities. The results brought forth in this work may be of great relevance and usefulness to the government in the formulation of a legal and regulative policy to the business park, longing for better strategic decisions. The present work brings forth data, images, maps, tables, charts, among other kinds of information, which makes its reading more dynamic and understandable in its theoretical discussion.

Abstract:

Godstransporter ökar i takt med att utrikeshandeln växer, vilket bidrar till utsläpp av växthusgaser. Hållbar utveckling och miljö är viktiga faktorer i dagens samhälle vilket gör att det ställs krav på nya och innovativa transportlösningar. Ett alternativ att bemöta dessa krav är genom högkapacitetstranporter, som i dagsläget testas, utförs och forskas kring frekvent i Sverige. Högkapacitetstransport avser lastbilsfordon som är längre och/eller tyngre än dagens konventionella lastbil som har fått dispens att trafikera vissa zoner på det svenska vägnätet. Denna studie baseras på att utvärdera två intermodala transportlösningar för transport av gods på sträckan mellan Göteborgs hamn och Viared, Borås. Den ena transportlösningen baseras på högkapacitetstransport och den andra baseras på en järnvägsbaserad transportlösning. De alternativa transportlösningarna utvärderas med avseende på effektivitet omfattande transportkostnad, flexibilitet och tid samt miljöpåverkan omfattande koldioxidutsläpp genom en fallstudie.Slutsatserna har resulterat i att högkapacitetstransport genererar en högre transporteffektivitet jämfört med dagens dragbil som trafikerar den utpekade vägsträckan i fallstudien. I brist på material har inga konkreta kostnader kunnat beräknats för de olika transportlösningarna. Däremot kunde en slutsats dras kring att de alternativa transportlösningarna ej bör uppgå till en högre kostnad än vad dagens transportlösning genererar. Ur miljösynpunkt har koldioxidutsläpp för de olika transportlösningarna beräknats. Implementeras hela vägsträckan med högkapacitetstransport har resultatet gällande koldioxidutsläpp genererat i en minskning med 30,6 procent jämfört med dagens dragbil. Däremot visade studien att järnvägstransporten vinner miljömässiga fördelar då den jämfört med dragbilen som trafikerar vägsträckan idag reducerar utsläppen med 80,4 procent. Dock visar koldioxidutsläppet i den intermodala järnvägslösningen att vägtransporterna bidrar med 98 procent av utsläppen.Denna studie väger för- och nackdelar gentemot varandra för en implementering av högkapacitetstransport. Högkapacitetstransporten jämförs även gentemot järnvägens för- och nackdelar vid transport av containergods. Studien bidrar dessutom till att stärka och reflektera över tidigare publicerade studier som finns inom ämnet.
Freight transport increases as foreign trade grows, which contributes to greenhouse gas emission. Sustainable development and the environment are important factors in today's society, which imposes demands on new and innovative transport solutions. One way of meeting these demands is through high capacity transports, which are currently being tested, performed and researched frequently in Sweden. High capacity transport refers to truck vehicles that are longer and/or heavier than today's conventional truck that has been given the dispensation to traffic certain areas on the Swedish road network. This study is based on evaluating two intermodal transport solutions for the carriage of goods on the route between Port of Gothenburg and Viared, Borås. One transport solution is based on high capacity transport and the other is based on a rail-based transport solution. Through a case study, the alternative transport solutions are evaluated based on efficiency, including transportation costs, flexibility and time, and the environmental impact including CO2 emissions.The conclusions have resulted in high capacity transport generating a higher transport efficiency compared with today's truck that operates the designated road distance in the case study. In lack of material, no concrete costs have been calculated for the various transport solutions. On the other hand, a conclusion could be drawn that alternative transport solutions should not be at a higher cost than today's transport solution results in. From an environmental point of view, CO2 emissions for the various transport solutions have been calculated. Implementing the entire road haulage with high capacity transport has resulted in a reduction of CO2 emissions by 30,6 percent compared to the current truck. On the other hand, the study showed that rail transport wins environmental benefits, as compared to the truck that carries the route today, emissions reduce by 80,4 percent. However, CO2 emissions in the intermodal railroad solution show that road transport contributes 98 percent of emissions.This study weighs strengths and weaknesses towards each other for the implementation of high capacity transport on the designated route. High capacity transport is also set against the railroad with pros and cons of transporting container goods. The study also contributes to strengthening and reflecting the theory from previously published studies within the subject.

Abstract:

The current trend in psychiatric health care is towards comprehensive primary healthcare for all South Africans. This has been has been achieved by the restructuring of the National Health System (NHS) into national, provincial, district, and community levels, which provide outpatient and inpatient care at primary, secondary, and tertiary care levels. Assessment and treatment in the form of physical and psychosocial interventions form an integral part of psychiatric care. The value of personality assessment and, in particular, the potential for matching patient personality types with effective treatment options, may play a role in facilitating effective health care in the future. An overview of the literature indicates that little research has been done regarding the area of personality traits of psychiatric patients in South Africa. This study aims to explore and describe the personality traits or profile of individuals attending a private psychiatric day care facility in The Nelson Mandela Metropole (i.e., Parkwood Day Clinic). The sample consisted of 196 participants (104 male and 92 female) who attended a group programme from April 2000 to April 2001. As part of the programme, patients were required to com plete a series of pencil-and-paper measures. The questionnaires selected for this study included a biographical questionnaire, which was used to describe the biographical variables of the sample with regard to gender, age and marital status, and The Revised NEO Personality Inventory (NEO PI-R) (Costa & McCrae, 1992a), which was used as a measure of personality. The NEO PI-R is considered a concise measure of the five major domains of personality and some of the more important traits that define each domain. Together, the five domains Neuroticism (N), Extraversion (E), Openness (O), Agreeableness (A) and Conscientiousness (C), and the six facets within each domain, allow for a comprehensive assessment of adult personality. xiv An exploratory, descriptive method was used in the study, and the data was analysed using descriptive and inferential statistics, including correlations, cluster analysis, and multivariate analysis of variance. Key findings include the following: Results from the NEO PI-R domains showed a personality profile of very high scores for N, and average scores for E, O, A, and C. Within the sample, cluster analysis revealed five distinct personality profile clusters. For the biographical variable gender, significant differences were found between males and females on N, with the majority of males scoring in the category of Very High and High, and the majority of females scoring in the Average category. For the variable age, the results indicated significant differences on A, with participants in the young adulthood group scoring significantly lower on A than participants in the middle adulthood group. For marital status, on the domain of O, significant differences were found between the divorced or widowed and the married, with the married scoring in the Low category and the divorced or widowed in the Average category. On the domain of C, significant differences were noted between the singles group and the currently or previously married groups, with the single group tending to score lower on C than both other groups. These findings reveal a need for further research into personality traits and psychiatric samples, as consideration of personality traits based on the profile established, may be useful in matching patients’ characteristics with optimal treatment options.

Abstract:

Building on interviews with young activists of the Euromaidan movement, this paper examines the possibilities for civil society engagement in today’s Ukraine. In Ukraine, the level of civil society engagement is one of the lowest in the postsoviet world, while at the same time millions of people take part in large protest movements. The material shows that, and present explanations to why, young people who are keen to engage do so in many ways, without this engagement resulting in a long-term civil society engagement.

Tendo em vista a importância socioeconômica da cultura da goiabeira, notadamente para a região nordeste do Brasil onde há limitada disponibilidade de água de boa qualidade, surge a necessidade do uso de águas salinas para produção agrícola implicando na necessidade do desenvolvimento de estratégias que possam viabilizar o seu uso. Nesse sentido, realizou-se a pesquisa com o intuito de avaliar os efeitos de diferentes doses de potássio combinadas com águas de distintos níveis salinos na produção de mudas para porta-enxerto de goiabeira. O experimento foi desenvolvido em casa de vegetação do Centro de Ciências e Tecnologia Agroalimentar da Universidade Federal de Campina Grande, Pombal - PB. O delineamento experimental foi em blocos casualizados, num esquema fatorial 5 x 4, com os tratamentos referentes à cinco níveis de condutividade elétrica da água de irrigação (CEa = 0,3; 1,1; 1,9; 2,7 e 3,5 dS m-1) em interação com quatro doses de potássio (70, 100, 130 e 160% de K) sendo a dose recomendada de 100% K (726 mg de K dm-3 de substrato) para mudas de goiabeira e quatro repetições, sendo cada parcela constituída por duas plantas úteis. A aplicação dos tratamentos teve início aos 40 dias após a emergência das plântulas (DAE). Os porta-enxertos foram avaliados aos 120 e 225 DAE, através da altura da planta, diâmetro do caule, número de folhas e área foliar; no período de 60 a 225 DAE foram mensuradas as taxas de crescimento absoluto e relativo para altura de planta e, aos 225 DAE a área foliar específica, as variáveis de fitomassa seca de caule, folhas, seca de raiz, parte aérea, total, relação raiz/parte aérea, razão de área foliar e o índice de qualidade de Dickson. A irrigação com água de CEa de até 1,9 dS m-1 possibilitou a formação de porta-enxerto de goiabeira cv. Paluma com redução aceitável em seu crescimento; dose de potássio de 798,6 mg de K dm-3 de substrato promoveu o maior crescimento em altura do porta-enxerto de goiabeira cv. Paluma aos 120 dias após a emergência; doses crescentes de K não atenuaram os efeitos nocivos dos sais sobre os porta-enxertos de goiabeira cv. Paluma; dose de 508,2 mg de K dm-3 de substrato favorece o acúmulo de fitomassa seca de caules de goiabeira cv. Paluma aos 225 DAE; irrigação com água de CEa 1,9 dS m-1 promove redução aceitável de 10% sobre a produção de fitomassa e qualidade dos porta-enxertos de goiabeira cv. Paluma; não houve interação significativa (sal x doses de K) sobre as variáveis estudadas.
Considering the socioeconomic importance of the guava crop, especially for the northeastern region of Brazil where there is limited availability of good quality water, the need arises for the use of saline waters for agricultural production, implying the need to develop strategies that can their use. In this sense, the research was carried out to evaluate the effects of different doses of potassium combined with waters of different salt levels in the production of seedlings for guava rootstock. The experiment was carried out in a greenhouse at the Agrifood Science and Technology Center of the Federal University of Campina Grande, Pombal - PB. The experimental design was a randomized complete block design, in a 5 x 4 factorial scheme, with the treatments referring to five levels of electrical conductivity of the irrigation water (CEw = 0,3; 1,1; 1,9; 2,7 and 3,5 dS m-1) in interaction with four doses of potassium (70, 100, 130 and 160% K) and the recommended dose of 100% K (726 mg K dm-3 substrate) for guava seedlings and four repetitions, each plot consisting of two useful plants. The treatments were started at 40 days after emergence of the seedlings (DAE). The rootstocks were evaluated at 120 and 225 DAE, through plant height, stem diameter, number of leaves and leaf area; in the period from 60 to 225 DAE, absolute and relative growth rates were measured for plant height and, at 225 DAE, the specific leaf area, stem dry matter, leaves, root dry matter, shoot, total ratio root/shoot, leaf area ratio and Dickson quality index. Irrigation with CEw water of up to 1,9 dS m-1 allowed the formation of a guava rootstock cv. Paluma with acceptable reduction in its growth; potassium dose of 798,6 mg of K dm-3 substrate promoted the highest growth in height of the guava rootstock cv. Paluma at 120 days after the emergency; increasing doses of K did not attenuate the harmful effects of the salts on guava rootstocks cv. Paluma; dose of 508,2 mg of K dm-3 of substrate favors the accumulation of dry phytomass of cv. Paluma at 225 DAE; irrigation with CEw water 1,9 dS m-1 promotes a 10% acceptable reduction on the phytomass production and quality of guava rootstocks cv. Paluma; there was no significant interaction (salt x doses of K) on the studied variables.

The experiment was carried out at the Experimental Station of Itambé, from the Pernambuco Agricultural Research Enterprise (IPA), aiming to evaluate different morphologic descriptors and the chemical composition of different dwarf clones of Pennisetum sp. as well as to estimate the heritability of several characters. Nine clones of dwarf elephant-grass were used (Taiwan A.146 - 2.14, Taiwan A.146 - 2.27, Taiwan A.146 - 2.37, Taiwan A.146 - 2.114, Merker México - 6.2, Merker México - 6.5, Merker México - 6.31, cv. Mott, CNPGL92F198.7). The experimental area was established in the beginning of April/2005. It was used vegetative propagation, using stem fractions. The experimental design used was randomized blocks with three replications. It was performed a manual staging cut at 10 cm from ground level, in May of 2005, followed by five cuts with 60 dayintervals at 10 cm from ground level. The morphologic descriptors were applied after 60 days of the staging cut. At the harvest time, the clones were characterized morphologically, and two types of estimates were used: grading scale through visual observations(descriptors) and direct measures (direct in the plant). An indirect measurement of character desirability was also performed. For the study of the chemical composition, it was utilized the clones that survived from the morphologic evaluations. All clones presented semi-erectleaves, with grading average of 3,73, except for the clone Taiwan A.146 - 2.37 that presented tendency to have more erect leaves. Regarding the intensity of basal tillering, the clones Merker México - 6.2, Merker México - 6.5, and Taiwan A.146 - 2.14 presented the smallest grades (3.93, 3.93, and 4.40, respectively). The intensity of axial tillering was absent in the clone Merker México - 6.2 with grade 1.93, medium for the clone Taiwan A.146 - 2.37 which received grade 5.66, and low for the remaining clones. In a general way, average intensity of total tillering was observed among the clones, indicating that the materials may be used in forage banks as well as under grazing. The tallest plants were the ones that presented larger desirability, therefore, this characteristic should be considered in the selection. The heritability estimate was high for all the appraised characters in dwarf elephant-grass. For DM production, leaf/stem ratio, and the concentration of DM, NDF, andNFC, no differences were observed (P <0.05) among the clones. For leaf CP, the clone Mott(14.1%) was superior to the clone Taiwan A. 146-2.114 (12.0%), but did not differ from other clones. The concentration of TCH and NFC didn't differ (P>0.05) for leaf of dwarf elephant-grass clones under cut at 60 days of regrowth, presenting averages of 74.4 % and 14.8 % for TCH and NFC, respectively. For stem CP, the clone Mott (12.3 %) was superior than clone Taiwan A.146 - 2.27 (9.0 %) and didn't differ from the others. For ADF, the clone Taiwan A.146 - 2.37 (42.0 %) was superior to the clone Mott, not differing from the others. The clones Taiwan A.146 - 2.37, originated from the IPA/UFRPE breeding program, was similar to the Mott cultivar. Heritability values showed genetic variability among clones at 60 days of regrowth. Some morphologic descriptors applied allowed to characterize theevaluated genotypes. The clones Taiwan A. 146-2.27, Taiwan A. 146-2.37, Taiwan A. 146- 2.114, and Merker Mexico 6.31 were taller, showed greater total tillering intensity, and were more desirable. As a results, these clones have greater potential for use under cut.
O experimento foi realizado na Estação Experimental de Itambé-PE, pertencente a Empresa Pernambucana de Pesquisa Agropecuária (IPA), objetivando avaliar diferentes descritores morfológicos, a produtividade e a composição química de clones de Pennisetum sp. de porte baixo sob competição, bem como estimar herdabilidade de caracteres. Foram utilizados nove clones de Pennisetum sp. de porte baixo (Taiwan A.146 – 2.14, Taiwan A.146 – 2.27, Taiwan A.146 – 2.37, Taiwan A.146 – 2.114, Merker México – 6.2, Merker México – 6.5, Merker México – 6.31, cv. Mott, CNPGL92F198.7). A área experimental foi implantada no início do mês de abril/2005, utilizando-se colmos fracionados. O delineamento experimental utilizado foi o de blocos casualizados com três repetições. Foi realizado corte manual de uniformização em maio de 2005, seguidos de cinco cortes com intervalos de 60 dias de crescimento a 10 cm do nível do solo. Os descritores morfológicosforam aplicados após 60 dias do corte de uniformização. Por ocasião das colheitas, os clones foram caracterizados morfologicamente, onde dois tipos de estimativas foram utilizadas: notas, por meio de observações visuais (descritores) e medidas diretas na planta, também foram determinados de forma indireta na planta o caráter desejabilidade (DES). Para a avaliação da composição química, foram estudados os clones sobreviventes durante aavaliação morfológica. Para a variável posição da lâmina foliar, todos os clones apresentaram folhas semi-eretas, com média das notas de 3,73, com exceção do clone Taiwan A.146 – 2.37 que apresentou tendência a ter folhas mais eretas, recebendo nota 2,7. Com relação à intensidade de perfilhamento basal, os clones Merker México – 6.2, Merker México – 6.5, Taiwan A.146 – 2.14, apresentaram as menores notas, sendo de 3,93; 3,93 e 4,40, respectivamente. A intensidade de perfilhamento axilar foi ausente no clone Merker México – 6.2, com nota 1,93, baixa para os demais e média para o clone Taiwan A.146 – 2.37 (5,66). De maneira geral, foi observada média intensidade de perfilhamento total entre os clones, indicando que os materiais podem ser utilizados, na forma de capineira, como também sob pastejo. Os clones de Pennisetum sp. de porte baixo, com maior altura, foram os que apresentaram maior desejabilidade, devendo estas características serem consideradasno momento da seleção. A estimativa da herdabilidade foi alta para todos os caracteres avaliados. Para produção de MS, relação folha/colmo e teores de MS, FDN e CNF, não foram observadas diferenças (P<0,05) entre os clones. Para PB da folha, o cv. Mott (14,1%) foi superior ao clone Taiwan A. 146-2.114 (12,0%), não diferindo dos demais. Os teores de CHT não diferiram (P>0,05) para folha, apresentando médias de 74,4%. Já para o colmo, o clone Taiwan A. 146-2.37 (79,5%) foi o que apresentou maior teor, diferindo (P<0,05) apenas do cv. Mott (73,9%). Para PB do colmo, o cv. Mott apresentou maior teor (12,3%) do que o clone Taiwan A.146 – 2.27 (9,0%) que não diferiu dos demais. Para FDA do colmo, o clone Taiwan A.146 – 2.37 (42,0%) foi maior do que o clone Mott (36,3), não diferindo dos demais. Nas condições da Zona da Mata Norte de Pernambuco, a maioria dosclones avaliados foram similares quanto à produção de MS, a relação folha/colmo, e composição nutricional. O clone Taiwan A.146 – 2.37, gerado pelo programa de melhoramento IPA/UFRPE, foi semelhante ao cultivar Mott. Os valores de herdabilidade indicam que os clones apresentaram variabilidade genética aos 60 dias de idade. Alguns descritores aplicados permitiram caracterizar os genótipos avaliados, sendo os clonesTaiwan A. 146-2.27, Taiwan A. 146-2.37, Taiwan A. 146-2.114 e Merker México 6.31, os que apresentaram maior altura e maior intensidade de perfilhamento total, além de apresentararem maior desejabilidade, revelando maior potencial para serem utilizados sobcorte.

Abstract:

This research explored different catalytic cracking zeolite additives to improve propylene selectivity and minimize dry gas yield. A comprehensive study of the effect of zeolite structure, pore system and crystal size on maximizing propylene production in FCC unit and the effect of post synthetic modifications on the physicochemical properties and cracking activity of ZSM-5 was investigated using X-ray diffraction (XRD), pyridine adsorption fourier transform infra-red (FTIR), 27Al and 29Si magic-angle spinning nuclear magnetic resonance (MAS NMR) and the catalytic cracking using n-heptane, as a model compound for heavy naphtha. The catalytic performances of these additives were evaluated in a fixed-bed reactor unit using n-heptane as a model compound for naphtha at temperatures 450 - 500 oC and W/F 38 - 92 gcat.h/mol. A range of zeolites were tested with ZSM-5 showing the optimum results at high feed conversion. Further studies on ZSM-5 crystal size illustrated that nano ZSM-5 (300 nm) was superior compared to the regular ZSM-5 (2000 - 4000 nm) in achieved conversion level and propylene selectivity. These improvements were attributed to the shorter path lengths for the reactant reducing diffusion constraints significantly. Modifying nano ZSM-5 acidity using steaming, acid leaching and silanation showed significant improvement over nano ZSM-5 parent. Mild steaming of nano ZSM-5 improved both n-heptane conversion and propylene selectivity whilst severe steaming only improved propylene selectivity. This work attempted to address the often discussed catalytic activity enhancement from mild steaming and identified newly created moderate acid sites as the source of increased activity. Dealumination by acid leaching decreased the total aluminium content of nano ZSM-5 and changed the Brønsted/Lewis ratio. Increasing the B/L ratio, increased the conversion and propylene selectivity. In addition, this research focussed for the first time on the silanation of nano ZSM-5 and its effect on n-heptane cracking, in particular, propylene and dry gas selectivity. Silica was deposited on the external surface of nano ZSM-5 neutralising the acidic sites and as a result, dry gas yield was significantly decreased due to the elimination of non-selective cracking. However, the trade off with conversion was high.

Abstract:

Abstract This research examines the lower edge of arable land in cultivating littoral land and its effects on spring sowing Central Ostrobothnia and in the southern areas of Northern Ostrobothnia. This doctoral thesis develops methods to raise the lower edge of arable land in low littoral land. The methods are based on contribution margin, the gross profil of yield, the relocation of dry margin and the realigning of littoral land's area descriptor. In addition, outdated littoral land profil and loss evaluation criteria are renewed. The objective of the research is to decrease environmental damages and to improve cultivation. Another objective in raising the lower edge of arable land is to enhance the forming of protective noncultivated belts. Ten lakes from the hydrologic areas of the rivers Perhonjoki, Kalajoki and Pyhäjoki were chosen for the research, one half of them were in their natural state and the other half were regulated. The research consisted of comparing the sowing dates and patch yields (moisture content 14%) of the sample parcels (104 observations) chosen from littoral land around the lakes to the corresponding figures of sample parcels selected from outside the areas influenced by water level variation. The findings are from 1985–1991 and 1996–1998. The cultivated plants were barley, oats and hay. The sample area research was completed with interviews. Furthermore, the research examined the dependence of air pore space of the soil cultivation layer on the dry margin. The research result indicate that the lower edge of arable land has to be raised, for lakes in their natural state the rise would be on average 35 ± 4 cm (67 observations) and for regulated lakes on average 39 ± 4 cm (61 observations). The minimum dry margins required by soil cultivation and sowing will be 69 ± 5 cm (67 observations) and 78 ± 5 cm (61 observations). Thus, the lowest part of the waterfront will not be cultivated anymore. The contribution margin of the field is not changed. Sowing can be done earlier and air pore space and viability increase. The condensation detriment of the soil cultivation layer, the workload needed for cultivation and the nutrient load in hydrologic areas will be decreased. Measuring and locating protective non-cultivated belts becomes easier. The state of environment is improved. The evaluation of profit and loss is modernized
Tiivistelmä Tutkimuksessa tarkastellaan rantamaiden viljelyksessä pellon alarajaa ja sen vaikutuksia kevätkylvöihin Keski-Pohjanmaalla ja Pohjois-Pohjanmaan eteläisellä osalla. Työssä kehitetään katetuottoon, sadon bruttotuottoon, kuivavaran siirtoon ja rantamaan pinta-alan kuvaajan oikaisuun perustuvat menetelmät pellon alarajan määrittämiseksi alavilla rantamailla. Samoin pyritään nykyaikaistamaan rantamaiden hyödyn- ja vahingonarviointia. Tutkimuksen tavoitteena on vähentää viljelyn aiheuttamia ympäristöhaittoja sekä parantaa samalla itse viljelyä. Pellon alarajan määrittämisen yhteydessä on tavoitteena edistää myös suojavyöhykkeiden perustamista. Kohdejärvinä oli Perhonjoen, Kalajoen ja Pyhäjoen vesistöjen kymmenen järveä, joista puolet oli luonnontilaisia ja puolet säännösteltyjä. Järvien rantatiloilta valittujen koelohkojen (104 kpl) kylvöaikoja ja ruutusatoja (kosteuspitoisuus 14 %) verrattiin vedenkorkeuksien vaihteluista riippumattomien vertailulohkojen vastaaviin arvoihin. Havaintovuodet olivat 1985–1991 sekä 1996–1998. Viljelykasveja olivat ohra ja kaura sekä heinä. Koealuetutkimuksia täydennettiin haastatteluina. Lisäksi tarkasteltiin muokkauskerroksen ilmahuokostilan riippuvuutta kuivavarasta määritettynä järven vedenkorkeudesta. Tutkimustulosten mukaan pellon alarajaa on korotettava nykyisestään luonnontilaisilla järvillä keskimäärin 35 ± 4 cm (n = 67) ja säännöstellyillä järvillä keskimäärin 39 ± 4 cm (n = 61). Kylvön vaatimat kuivavarat määritettyinä järvien vedenkorkeuksista tulevat olemaan vastaavasti 69 ± 5 cm (n = 67) ja 78 ± 5 cm (n = 61). Tällöin rantalohkon alavimmalta osalta viljely poistuu. Pellon katetuotto ei muutu. Kylvö aikaistuu, ilmahuokostila kasvaa ja kulkukelpoisuus paranee. Muokkauskerroksen tiivistymishaitta ja viljelyn työnmenekki sekä vesistöön kohdistuva ravinnekuormitus vähenevät. Suojavyöhykkeiden mitoitus ja sijoitus helpottuvat. Ympäristön tila paranee. Hyödyn ja vahingon arviointi nykyaikaistuu

Dry-set mortars are widely used in civil construction, and are made basically of cement, sand, water and admixtures. However, their factories are located far from the city of Porto Velho, in the industrial nuclei of Brazil, most of them in São Paulo, which rises the final price of the product. This research aimed to develop a dry-set mortar using sands extracted in Porto Velho.Two types of quartz sands extracted from the river, Celotex K60® chemical admixture and CP IV-32 cement were used in the formulation of three distinct mix proportions of mortar. In order to characterize the sands, there were made tests measuring their density, unit mass, moisture and granular distribution. The mortarswere characterized by the tests of water retention rate, tensile bond strength, axial compressivestrength, diametralcompressive strength, and also by the evaluation of thecracking pattern of the specimens. The results have shown that both sands have similar physical and granulometric properties, in the other hand, it was possible to notice the relationship between the bulk density fresh and the water retention. It was also seen that as the sand was increased as the bond and compressive strength were decreased.It is concluded that the Sand A has a better performance than Sand B in terms of dry-set mortar composition,the mix proportion 1:3 (cement and sand) gives better results, however the mix proportion 1:4 has more suitable characteristics in terms of Brazilian standard for Industrial Mortars.
Argamassas colantes são materiais muito empregadas na construção civil, e constituídas basicamente de cimento, areia, aditivos e água. Contudo, as mesmas são produzidas nos grandes centros industriais do país, principalmente no estado de São Paulo, muito distante da cidade de Porto Velho – RO, o que eleva o custo final do produto. O objetivo desta pesquisa é desenvolver uma Argamassa Colante Tipo ACI, utilizando areias do município de Porto Velho. Para tanto, foram utilizadas duas areias quartzosas de rio, aditivo químico Celotex K60® e cimento CP IV-32 para formulação de três traços das argamassas. Para caracterizar as areais foram realizados ensaios para determinar massa unitária, massa especifica e umidade superficial, bem como a distribuição granulométrica. Para caracterizar a argamassa foram realizados ensaios para determinar o percentual de retenção de água, a resistência de aderência e resistência a compressão axial e diametral, além da avaliação do padrão de fissuração dos corpos de prova. Os resultados mostraram que ambas as areias possuem propriedades físicas e granulometria bastante semelhantes; já quanto às argamassas foi possível notar a relação entre massa especifica fresca com o índice de retenção de água, e também que a medida que aumenta a quantidade de areia ocorre a redução da resistência tanto de aderência quanto de compressão. Assim, concluir que a areia A tem desempenho melhor na composição das argamassas quando se compara com a areia B, e que o traço 1:3 (cimento:areia) apresenta melhores resultados, contudo a composição 1:4 possui características adequadas para atender as normas para argamassa colante industrializada.

Abstract:

In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. The proposed simplified tablet model describing the fracture path in a tablet during strength testing offers an explanation for the increase in tablet strength caused by the binder. The model and results in this thesis indicate that fractures will usually propagate around the tablet particles and through the interparticulate voids during tablet strength testing.

One important characteristic of the binder is its ability to be effectively and evenly distributed through the interparticulate voids in a compound tablet. Characteristics such as high plasticity, low elasticity and a small particle size were associated with a more even distribution and a consequent pronounced effect on pore structure and marked improvement in tablet strength. The strength of tablets containing less plastic binders was governed more by the compactibility of the binder. The tablet porosity, bonding mechanisms and volume reduction mechanisms of the compound also influenced the effect of the binder. For example, the plasticity and particle size of the binder had the most significant effects on tablet strength when the tablet porosity of the com-pound was relatively low. A combination of the plasticity and the compactibility of the binder determined the strength of tablets when the tablet of a compound was more porous. The positive effect of a binder on pore structure and tablet strength resulted in an increase in the disintegration time. Although addition of a superdisintegrant generally improved the disintegration time, the effect was decreased when the formulation included more deformable binders.

The choice of a suitable binder for a tablet formulation requires extensive knowledge of the relative importance of binder properties for enhancing the strength of the tablet and also of the interactions between the various materials constituting a tablet. Thus, the increased knowledge of the functionality of a binder obtained in this thesis enables a more rational approach to tablet formulation.

A partir da imagem da Casa de Portugal (um navio-imitação das caravelas portuguesas cravejado de símbolos de exaltação ao colonialismo) atracada em frente ao Porto Maravilha, durante as Olimpíadas de 2016, a dissertação pretende refletir sobre as formas como a violência colonial é pensada, incorporada e ignorada temporal e espacialmente na sociedade contemporânea brasileira. Para isso, a pesquisa parte desta imagem específica para uma análise mais ampla do projeto Porto Maravilha, com atenção a alguns dos espaços erguidos e/ou reformados por ocasião dos Jogos Olímpicos de 2016, e circuitos a pé feitos na região. Trabalha-se com a contraposição de uma concepção disciplinadora do espaço (Porto Maravilha) e a ideia de espaço-palimpsesto, representado pela própria zona portuária e que se caracteriza como um espaço em que se sobrepõem diferentes camadas de tempo, de modo a afirmar coexistências, encontros, conexões. A hipótese a ser investigada é a de que a condição de possibilidade para pensar um futuro de progresso, no âmbito do Porto Maravilha, seria a noção de uma reconciliação do Rio com seu passado violento e, portanto, o restabelecimento de uma suposta harmonia que é vista como própria à cidade e aos brasileiros em geral. Tal narrativa, por sua vez, envolve diretamente a noção de que o que funda o Brasil é o encontro colonial harmônico entre diferentes raças e culturas.
Through the image of House of Portugal (a copy of Portuguese sailing ships used during colonial navigations) anchored in front of Porto Maravilha, during 2016 Olympic Games, this thesis intends to reflect upon the ways colonial violence is thought of, embraced and ignored temporally and spatially by Brazilian contemporary society. For such, this research departs from this specific image to a broader analysis of Porto Maravilha project, focusing on spaces built and/or renewed for the Olympics and walking tours taken around the port zone. The thesis works with the contrast of a disciplinary conception of space (Porto Maravilha) and the idea of space-palimpsest, represented by the port zone itself and where different histories overlap, find points of connection and continuities and also break into each other. The hypothesis to be investigated is that the condition of possibility to think about a future of progress, in the context of Porto Maravilha, would be the notion of reconciliation between Rio de Janeiro and its violent past, and therefore the reestablishment of a supposed harmony seen as proper to the city and to Brazilians in general. Such narrative, in turn, directly entails the notion that what founds Brazil is a harmonic colonial encounter between different races and cultures.

Abstract:

O objetivo deste estudo é verificar se a apresentação das despesas por função na DRE proporciona menor capacidade preditiva aos usuários, especialmente aos analistas de mercado, comparada à apresentação das despesas por natureza. O CPC 26 permite duas formas de apresentação das despesas na DRE, função ou natureza, o que é caracterizado como uma escolha contábil de apresentação. No entanto, se a empresa optar pela divulgação por função, deve apresentar, também, a informação por natureza em nota explicativa, dado que essa informação apresenta capacidade preditiva, segundo o IASB. No Brasil, a lei 6.404/76 induz a maioria das empresas a divulgar as despesas por função, o que torna a informação por natureza disponível, também, para a maioria das companhias. Existem estudos que analisam como os critérios de mensuração e reconhecimento afetam a capacidade preditiva da informação divulgada. Outros trabalhos sugerem que as escolhas contábeis de reconhecimento e mensuração podem interferir na acurácia das projeções dos analistas de mercado. Entretanto, a forma como a escolha de apresentação dos itens na DRE interfere na capacidade preditiva dos usuários, especialmente para os analistas de mercado, não está suficientemente clara na literatura. Mais especificamente com relação à forma de apresentação das despesas, não se sabe se a escolha de um método em detrimento de outro pode impactar a qualidade da informação para o usuário. Então, foram analisadas 54 empresas brasileiras de capital aberto, pertencentes a seis setores da BOVESPA, durante um período de cinco anos, por meio da utilização de análise de dados em painel. De um modo geral, os resultados sugerem que a informação por natureza é mais preditiva para o usuário e que os analistas podem errar menos em suas projeções de resultado com o uso da informação sobre despesas apresentada por natureza, dado que esta informação é disponibilizada em nota explicativa nos demonstrativos contábeis das companhias brasileiras. Assim, o estudo traz evidências de que a escolha da forma de apresentação das despesas na DRE não é indiferente para o usuário, já que pode afetar a sua capacidade de predizer fluxos de caixa futuros. Além disso, como contribuição prática, espera-se mostrar que os analistas podem melhorar a acurácia de suas previsões ao utilizarem o método de apresentação das despesas por natureza para realizar suas projeções, especialmente quando analisam empresas com alto nível de custos fixos.
The aim of this study is to verify if the presentation of the expenses by function in the income statement provides less predictability to the users, especially to the market analysts, compared to the presentation of expenses by nature. CPC 26 allows two forms of presentation of expenses at the income statement, by function and by nature, what is characterized as an accounting choice of presentation. However, if the company opts for disclosure by function, it must also present information by nature in an explanatory note, given that this information presents predictive capacity, according to the IASB. In Brazil, the Law No. 6.404 /76 induces most of companies to disclose expenses by function, which makes the information by nature also available for most companies. Studies had already analyzed how measurement and recognition criteria affect a predictive capacity of the information disclosed. Other works suggest that accounting recognition and measurement choices may interfere in analysts\' forecasts. However, the way in which the choice of presentation of items in the income statement interferes in the predictive capacity of users, especially for market analysts, is not sufficiently clear in the literature. More specifically, regarding to expenses presentation, it is not known whether the choice of one method over another can generate differences for the predictive capacity of the user. It was analyzed a sample of 54 Brazilian publicly companies belonging to six sectors of BOVESPA over a five-year period, using panel data analysis. Overall, the results suggest that information by nature is more predictive for the user and that analysts can improve the accuracy of their forecasts using the information of expenses presented by nature, since this information is available in an explanatory note in the financial statements of Brazilian companies. Thus, the study provides evidence that the choice of expenses presentation at the income statement is important to the user, as it may affect their ability to predict future cash flows. Moreover, as a practical contribution, this study shows that analysts can improve the accuracy of their forecasts by using the method of presenting expenses by nature to carry out their projections, especially when analyzing companies with high fixed costs.

Abstract:

This study aims to investigate and analyse certain aspects regarding the current condition of the Philippines. Both of its culture and its polities, approached within perspectives of historical epochs of colonialism and its aftermaths regarding post-colonial discourse. The contemporary society of the Philippines has been deeply imprinted by its colonial legacies and left a profound mark on its culture, tradition and the development of its politics both from the institutional perspectives and international context. This project aims to confront some of the structural roots and causes that contribute to its national crisis such as mass poverty and the persisting oppression that permeates within the society of the Philippines, regarding its national identity and its global status as a former colony under western powers. The context of this project is about the enduring and uneasy relationship between the Philippines and the former western hegemonic powers, Spain in the late 15th century and the United States in the early 19th century, that have assumed territorial border in the archipelago. In which it has subsequently determined and consolidated, however constrained and inescapable, many of the historical, cultural and political formations that have influenced developmental trajectories in the Philippines Society.

Abstract:

Objetivos: Avaliar o consumo de frutas e vegetais por adolescentes, residentes em Porto Alegre, RS, e verificar sua associação com características demográficas. Métodos: Foram estudados 568 adolescentes, com 12 a 19 anos, em estudo transversal realizado em amostra aleatória representativa de Porto Alegre. Os dados foram coletados por meio de entrevista, administrando-se um questionário de freqüência alimentar (QFA) e perguntas específicas para avaliar o consumo de frutas e vegetais nas últimas 24 horas. O total de frutas e vegetais foi aferido através do QFA ou IR24h, permitindo criar seis grupos: frutas (QFA), vegetais (QFA), vegetais sem arroz (QFA), vegetais com arroz e feijão (QFA), arroz e feijão (QFA), Five-a-day (IR24h) e Five-a-day colorido (IR24h). Análises foram realizadas utilizando-se teste do qui-quadrado de Pearson, análise de variância e regressão linear múltipla. Resultados: A amostra foi constituída por meninos (49,5%), 50% brancos e com 7,5 ±2,5 anos de escolaridade. Cerca de 14,3% dos adolescentes apresentavam sobrepeso e 8,8% obesidade. Aproximadamente 60% dos adolescentes consumiam o número de porções de frutas e vegetais recomendados, mas apenas 22% consumiam as cinco cores de frutas e vegetais por dia. Observou-se que 36,7% dos meninos e 31,0% das meninas consumiam menos do que uma porção de fruta por dia, sendo que 3,6% e 5,6%, respectivamente, ingeriam menos do que uma porção de vegetal por dia. O consumo de vegetais em geral e de arroz e feijão associaramse positiva e independentemente com gênero masculino e idade e inversamente com escolaridade. Conclusão: A adequação do consumo em relação às recomendações de frutas e vegetais foi facilmente alcançada na presença de arroz e feijão entre os adolescentes estudados. Intervenções são necessárias para aumentar a ingestão de frutas e vegetais para prevenir doenças não transmissíveis.
Purpose: To evaluate the consumption of fruits and vegetables by teenagers, residents in Porto Alegre, Brazil, and verify its association with demographic characteristics. Methods: We studied 568 adolescents, with 12 to 19 years in cross-sectional study conducted in random sample representative of Porto Alegre. The data were collected through interviews, managing to be a food-frequency questionnaire (FFQ), and specific questions to evaluate the consumption of fruits and vegetables in the last 24 hours. The total fruits and vegetables was benchmarked through the FFQ or IR24h, allowing create six groups: fruits (FFQ), vegetables (FFQ), vegetables without rice (FFQ), vegetables with rice and beans (FFQ), rice and beans (FFQ ), Five-a-day (IR24h) and Five-a-day color (IR24h). Analyses were performed, using the chisquare test of Pearson, analysis of variance and multiple linear regression. Results: The sample consisted of boys (49.5%), 50% white and with 7.5 ± 2.5 years of schooling. Approximately 14.3% of adolescents were overweight and 8.8% obesity. Approximately 60% of adolescents consumed the number of servings of fruits and vegetables recommended, but only 22% consumed the five colors of fruits and vegetables per day. It was found that 36.7% of boys and 31.0% of girls consumed less than one serving of fruit per day, of which 3.6% and 5.6%, respectively, ingested less than a serving of vegetable per day. The consumption of vegetables in general and rice and beans is positively associated with males and independently and inversely with age and education. Conclusion: The adequacy of consumption in relation to the recommendations of fruits and vegetables was easily achieved in the presence of rice and beans among teenagers studied. Interventions are needed to increase the intake of fruits and vegetables to prevent noncommunicable diseases.

Abstract:

O presente trabalho tem por objetivo estudar o cotidiano dos agregados sociais da Praça da Alfândega localizada no centro da cidade de Porto Alegre no Rio Grande Sul. Foram investigados a partir deste espaço os aspectos relacionais, identitários, as expressões subjetivas e estéticas, as fronteiras de convivências assim como as territorializações empreendidas pelos indivíduos que compõem estes agregados sociais no espaço da Praça da Alfândega. Além disso, esta dissertação tem como intuito discutir as questões pertinentes sobre a função do espaço público, cidadania e dos aspectos sobre as formas de sociabilidade e de insociabilidade nas metrópoles contemporâneas. Pode se dizer que a Praça da Alfândega, nesse mosaico de representações sociais, territórios justapostos e signos compreendem um importante lócus de análise do espaço urbano, motivo pelo fato que ela se apresenta para as formas sociais, denominado de agregados sociais um espaço dicotômico da sobrevivência material e da convivência social. Por esse motivo, o estudo do cotidiano dos agregados sociais presentes no espaço da Praça da Alfândega constituem também uma investigação sobre os fenômenos urbanos contemporâneos e suas múltiplas e emergentes práticas sociais se apresentam nos estilos de vida, das formas simbólicas e nos usos dos espaços nas grandes metrópoles.
This paper aims to study the social aggregations’ every day life from Praça da Alfândega, located in the center of Porto Alegre city in Rio Grande Sul. The aspects of relationship and identity, the subjective and esthetic expressions, the borders of acquaintance as well as the territories settled by people who compounded these social groups in the space of Praça da Alfândega were investigated. Besides, this paper also aims to discuss relevant questions about the function of public space, citizenship and aspects about the forms of sociability and unsociability in modern metropolis. It is possible to affirm that Praça da Alfândega, on this mosaic of social representation adjacent territories and symbols form an important locus of analysis about urban space. For this reason, it becomes a dichotomic space both of material survival and of social acquaintance for the social forms, called social aggregations. Because of this reason, the study of the social aggregations’ every day life settled in Praça da Alfândega constitutes also an investigation about recent urban phenomena and their several and emergent social practices according to ways of life, symbolical forms, and settlement in big cities.

Abstract:

This Project identified the relationships between storage conditions, dry matter losses (DMLs) caused by Fusarium species in cereal grains and mycotoxin contamination and assessed novel control strategies for post-harvest grain management including chemical control and ozone. F. graminearum, F. verticillioides and F. langsethiae were inoculated on wheat, maize and oats and stored under environmental conditions where marginal to optimum spoilage and mycotoxin contamination can occur. DMLs were calculated from the CO2 produced and were significantly correlated with deoxynivalenol (DON), zearalenone (ZEA), fumonisins (FUMs) and T-2 and HT-2 toxins respectively. Mycotoxin levels in wheat and maize exceeded the EU legislative limits with 0.9-1% DMLs. Therefore, CO2 monitoring during storage can indicate the level of contamination in a stored batch. Using CO2 production data at different water activity (aw) and temperature conditions, the environmental regimes at which F. langsethiae can grow and contaminate oats with T-2 and HT-2 toxins were identified for the first time. Five acids were examined in vitro and little effect was observed on Fusarium growth, in the aqueous form, while the effect on mycotoxin production varied. Dissolved in ethanol, adipic, fumaric and ferulic acids inhibited fungal growth and controlled DON and FUMs, but T-2 toxin was stimulated by the ethanol. Two garlic essential oils, propyl-propylthiosulfinate (PTS) and propyl propylthiosulfonate (PTSO) were studied for the first time. In vitro, 200 ppm reduced fungal growth (50-100%) and mycotoxin production by >90%. The efficacy was species-dependent. In naturally contaminated oats of 0.93 aw stored for 20 days, 16 ppm PTSO reduced T-2 and HT-2 toxins by 66% and ochratoxin A (OTA) by 88%, while 200 ppm PTS reduced OTA by 95%. In wheat, 100 ppm PTS reduced DON and ZEA and 300 ppm PTS reduced fumonisins by 40-80%. PTSO:PTS (1:1) at 400 and 600 ppm was very effective against DON and ZEA in wheat of 0.92 aw. Ozone (O3) exposure at 200 ppm for 30 min delayed Fusarium spore germination on media of 0.98 aw and inhibited germination at 0.94 aw. O3 was more effective against fungal spores than mycelium and little effect was observed on growing cultures. In vitro, mycotoxin production after exposure depended on the stage of life of the fungi. O3 reduced fungal populations in grains. Mycotoxin production in wet grains treated with 100-200 ppm O3 for 60 min and stored for up to 30 days was reduced or completely inhibited, depending on the species and the exposure system. Simultaneous drying of the grain due to the O3 passage was observed.

Abstract:

This thesis examines the role of local civil society organisations (CSOs) in representing and addressing local needs in hybridized peacebuilding processes in South Kivu, the Democratic Republic of the Congo (DRC). To do so it examines how local CSOs contribute to peacebuilding efforts, as well as who and what influence those contributions. Further, it considers the potential reach of such interventions at the community, provincial and national levels. The research for this thesis examines three locally founded and operated civil society organisations in Bukavu, South Kivu, whose efforts directly respond to known local causes of conflict in the region. Its findings demonstrate how they translate the needs and knowledge of community-level actors to external and international partners, from whom they receive funding and knowledge that support their ability to deliver peacebuilding projects that respond to those community-level needs. While their external international partners were found to maintain material power in relation to these peacebuilding interventions, the local CSOs were shown to hold significant discursive power in this role of translators and intermediaries in these processes. These findings challenge homogenous constructions of the local presented by post-liberal peacebuilding literature. They recognize the diversity of the local including individuals or groups who have been directly impacted by an ongoing violent conflict in a fixed geographical location whose experiences of war are shaped by their identities, and who share long-term interests in potential peace. Understanding the local in this way acknowledges a spectrum of actors contributing to peacebuilding in South Kivu and invites a reconsideration of binary constructions of hybridity. Acknowledging the important role that civil society and other intermediaries play in peacebuilding offers a foundation of understanding hybridity as a process of translation rather than shock.

Abstract:

Nas últimas décadas, observou-se um grande avanço no estudo das relações organizacionais com relação a saúde. O presente estudo teve por objetivo avaliar o impacto das condições bucais na qualidade de vida de pré-escolares matriculados em creches comunitárias no Município de Porto Velho-RO e verificar o perfil socioeconômico das famílias e seu estado nutricional. A amostra foi constituída por 210 pré-escolares entre 3 e 5 anos de idade onde foi adotado o Índice ceod para avaliação de cárie dentária e o Índice de Massa Corpórea para avaliação do estado nutricional. Foram aplicados questionários de avaliação de influência da saúde bucal na qualidade de vida (ECOHIS) e perfil socioeconômico aos pais ou responsáveis dos respectivos pré-escolares. A estatística descritiva foi realizada por meio de frequências relativas e absolutas e a sua análise por meio do teste de Correlação de Spearman (p<0,05). Foi encontrado um ceod de 2,11 (3,04) e um Sic Índice de 5,84 (2,59), observando-se 49,52% de crianças livres de cárie dentária. A classificação socioeconômica mostrou que 80,95% encontram-se na classe média inferior e que 40,29% tem renda familiar inferior a 2 salários mínimos. Quanto ao estado nutricional, 60,48% encontravam-se eutróficas e 25,71% magreza, não apresentando influencia significativa quanto a saúde bucal (p<0,05). Foi verificada relação estatisticamente significativa entre o ceod e seus componentes na qualidade de vida (p<0,05). Concluiu-se que o impacto das condições socioeconômicas e influência da saúde bucal na qualidade de vida de crianças na idade pré-escolar podem nortear novas práticas em saúde objetivando reduzir as desigualdades na distribuição da cárie dentária na população.
In recent decades, there was a major breakthrough in the study of organizational relationships for health. This study aimed to evaluate the impact of oral conditions on quality of life of preschool children enrolled in community day care centers in the city of Porto Velho-RO and assessed the socioeconomic profile of their families and their nutritional status. The sample consisted of 210 preschool children between 3 and 5 years of age where we adopted the dmft index for assessment of dental caries and body mass index to assess nutritional status. Questionnaires were applied to evaluate the influence of oral health on quality of life (ECOHIS) and socioeconomic profile of parents or guardians of their preschoolers. Descriptive statistics were performed descriptively by means of relative and absolute frequencies and their analysis using the Spearman correlation test (p<0.05). It was found a dmft of 2.11 (3.04) and a Sic Index 5.84 (2.59), with polarization of dental caries in the population studied (49.52%). The socioeconomic classification showed that 80.95% are lower middle class and 40.29% have incomes below two minimum wages. The nutritional status, 60.48% were normal weight and thinness 25.71%, showing no significant influence in the oral health (p<0.05). Statistically significant relationship was found between the dmft and its components in the quality of life (p<0.05). It was concluded that the analysis of the socioeconomic status and influence of oral health on quality of life for children in preschool can guide new practices aimed at reducing health inequalities in the distribution of dental caries in the population.

Abstract:

O presente trabalho refere-se ao desenvolvimento de grânulos a partir de produto seco de A. satureioides obtido por spray drying, em escala semi-industrial, visando a superar as principais limitações tecnológicas apresentadas tais como a higroscopia excessiva do produto, baixa densidade, pequeno tamanho de partícula e instabilidade dos constituintes flavonoídicos frente à luz. Dois métodos foram empregados para a granulação: granulação em leito fluidizado e granulação via seca por desagregação. Estes métodos apresentaram, respectivamente, 15 e 60 % de rendimento do processo, levando a escolha da granulação seca para a produção dos grânulos do produto seco. A granulação seca resultou em grânulos assimétricos, de faixa granulométrica situada entre 0,3 mm e 1,9 mm e de superfície irregular e rugosa. O revestimento destes grânulos foi realizado em leito fluidizado, utilizando três tipos de polímeros, Eudragit® L 30D, Opadry® II e Opadry® AMB.O rendimento médio com o Opadry® II foi de 72 %. O revestimento com Opadry® AMB foi realizado utilizando-se um baixo e alto fluxo do líquido de revestimento, obtendo-se rendimentos de 75 e 85 %, respectivamente. A higroscopia dos grânulos foi avaliada em ambientes com umidade relativa controlada de 65 ou 99 %, comparando-se o comportamento dos grânulos revestidos com o dos grânulos sem a presença de revestimento. Ambos os filmes com Opadry® não protegeram os grânulos frente à umidade. As fotomicrografias por MEV, destes grânulos, revelaram que, ambos os tipos de revestimento, apresentaram superfícies rugosas e com presença de poros explicando, parcialmente, a falta de proteção contra a umidade. O estudo da fotoproteção indica, em um primeiro momento, que o filme de revestimento promove a proteção dos flavonóides frente a ação da luz. A avaliação preliminar da liberação dos flavonóides, a partir dos grânulos, foi realizada em células de fluxo Desaga® com os grânulos sem revestimento e revestidos com Opadry® AMB. A água não demonstrou ser o meio mais favorável para este ensaio. Em meio com pH 1,2 contendo 1 % de laurilsulfato de sódio, os flavonóides quercetina, luteolina e 3-Ometilquercetina foram liberados, respectivamente, após 90 minutos, em 70, 83 e 70 % a partir dos grânulos não revestidos, e 52, 54 e 45 % a partir dos grânulos revestidos com Opadry® AMB, denotando a influência do filme de revestimento sobre o perfil de liberação dos flavonóides. Em seu conjunto, os resultados obtidos nesta primeira abordagem deste tema abrem diversas perspectivas para oaprofundamento do estudo e desenvolvimento de granulados de A. satureioides, a partir de produto seco por spray drying.
The present work was designed to develop granules from Achyrocline satureioides spray dried powders in order to overcome the main technological limitations presented by this herbal raw material: high hygroscopy, low density, small particle diameter and flavonoid sensibility against light. Two methods were employed for granulation, fluidized bed and dry granulation. These methods presented, respectively, 15 and 60 % of process yield, leading to the selection of dry granulation for preparing the granules. By this method, the granules showed 0,3 to 1,9 mm particle mean diameter, rough surface and irregular morphology. For coating the granules, three types of polymers were employed, Eudragit® L30D, Opadry® II and Opadry® AMB, in fluidized bed. The first one resulted in atomizer obstruction becoming non viable its employment. The mean yield coating obtained with Opadry® II was 72 %. The Opadry® AMB was sprayed in low and high rates yielding, respectively, 75 % and 85 %. The hygroscopicity of the granules was evaluated in controlled conditions of 65 % or 99 % RH, comparing the behavior of the coated granules which that presented by non-coated particles. Both Opadry® coatings did not protect the granules against the humidity. The SEM photomicrographis of these granules revealed that both types of coating presented rough and porous surface explaining partially, at least, the lack of protection against the humidity. The preliminary photostability assay indicated, in a first view, that the coating promotes the flavonoid protection. The flavonoid release from the granules was performed in Desaga® flow cell from the non-coated granules and from Opadry® AMB coated granules. Water demonstrated not to be an appropriate media for both tested granules. In pH 1.2 media containing 1 % of sodium lauryl sulfate, the flavonoids quercetin, luteolin and 3-O-methylquercetin were, respectively, released, after 90 minutes, in 70 %, 83 % and 70 % from non coated granules and in 52 %, 54 % and 45 % from Opadry® AMB coated granules, denoting the influence of the coating on the flavonoid release profile. Taken together, the results of this first approach openmay perspectives for more detailed studies on Achyrocline satureioides granules from the corresponding spray dried powders.

This study aimed to evaluate the effects of single doses of superphosphate and Araxa phosphate growth, dry matter production and chemical composition of forage, forage nutrient uptake, and chemical attributes of an Oxisol cultivated with Tifton 85. The study was conducted in an Oxisol clayey, during the period December 2010 to March 2012, in an area located at latitude 24º 42'49'' S and longitude 53º 44' 35'' W. The experimental design was randomized blocks in factorial scheme 2x5, with two phosphorus sources (triple superphosphate and phosphate Araxá) and five P rates (0, 40, 80, 120, 160 kg P2O5 ha-1), with four replications. On growth and forage production were determined dry matter production, canopy height, tiller density, leaf area and leaf/stem ratio during three growing seasons at intervals of 28 days. The chemical composition was studied by determining the levels of CP, NDF, ADF, lignin, hemicellulose and cellulose, while the mineral composition was studied by determining the levels of macro minerals (phosphorus, potassium, calcium, sulfur and magnesium) and trace (iron, manganese, zinc and copper) in forage Tifton 85 produced by growth in four intervals of 28 days. The nutrient uptake was studied by estimating the extraction of phosphorus, potassium, calcium, magnesium, manganese, copper, zinc and iron in forage produced by Tifton 85 during the four growth periods of 28 days. In soil, the samples were taken towards the close of the experiment, at 0-10 and 0.10-0.20 m, determining the values of pH, phosphorus, potassium, calcium, magnesium, the sum of bases, CEC, base saturation, and levels of copper, manganese, zinc and iron. In the evaluations of dry matter production, canopy height, tiller density and leaf area was significant effect of phosphorus levels. The bromatological constituents were changed only by periods of growth due to climatic conditions of each period and the levels of macro and micro minerals in the forage of Tifton 85 were not affected by sources of variation studied, except for phosphorus and sulfur. Significant effect of doses of phosphorus sources only for the extraction of phosphorus and phosphorus contents of the soil. Phosphorus fertilization with Araxa phosphate or triple superphosphate increases dry matter production, canopy height, tillering and leaf area of Tifton 85. The phosphorus and sulfur in the dry matter are increased with the dose delivery Araxa phosphate or triple superphosphate. The extraction of soil phosphorus by Tifton 85 and phosphorus increases more significantly with the application of doses of Araxa phosphate altered without the other characteristics of soil
A presente pesquisa teve por objetivo avaliar os efeitos de doses de Superfosfato simples e fosfato de Araxá no crescimento, produção de matéria seca e composição química da forrageira, extração de nutrientes pela forrageira, e nos atributos químicos de um Latossolo Vermelho cultivado com Tifton 85. O trabalho foi desenvolvido num Latossolo Vermelho eutroférrico de textura argilosa, durante o período de dezembro de 2010 à março de 2012, em uma área de localizada na latitude 24º 42' 49'' S e longitude 53º 44' 35'' W. O delineamento experimental adotado foi de blocos ao acaso em esquema fatorial 2x5, sendo duas fontes de fósforo (Superfosfato triplo e fosfato de Araxá) e cinco doses de fósforo (0; 40; 80; 120; 160 kg ha-1 de P2O5), com quatro repetições. No crescimento e produção da forrageira foram determinadas a produção de matéria seca, altura do dossel, densidade de perfilhos, área foliar e a relação folha/colmo durante três períodos de crescimento com intervalos de 28 dias. A composição bromatológica foi estudada determinando-se os teores de PB, FDN, FDA, lignina, hemicelulose e celulose; enquanto a composição mineral foi estudada determinando-se os teores de macrominerais (fósforo, potássio, cálcio, enxofre e magnésio) e microminerais (ferro, manganês, zinco e cobre) na forragem produzida pelo Tifton 85 em quatro intervalos de crescimento de 28 dias. A extração de nutrientes foi estudada estimando-se a extração de fósforo, potássio, cálcio, magnésio, manganês, cobre, zinco e ferro na forragem produzida pelo Tifton 85 durante os quatro períodos de crescimento de 28 dias. No solo, as amostragens foram realizadas ao findar do experimento, nas camadas de 0-10 e 0,10-0,20 m, determinando-se os valores de pH e os teores de fósforo, potássio, cálcio, magnésio, a soma de bases, CTC, saturação por bases e os teores de cobre, manganês, zinco e ferro. Nas avaliações da produção de matéria seca, altura do dossel, densidade de perfilhos, e área foliar houve efeito significativo apenas das doses de fósforo. Os constituintes bromatológicos foram alterados somente pelos períodos de crescimento devido às condições climáticas de cada período e os teores de macro e microminerais na forragem do Tifton 85 não foram afetados pelas fontes de variação estudadas, com exceção para o fósforo e o enxofre. Houve efeito significativo das doses de fontes de fósforo apenas para a extração de fósforo e para os teores de fósforo no solo. Adubação fosfatada com fosfato de Araxá ou superfosfato triplo aumenta a produção de matéria seca, altura do dossel, perfilhamento e área foliar do tifton 85. Os teores de fósforo e enxofre na matéria seca são aumentados com a aplicação de doses de fosfato de Araxá ou Superfosfato triplo. A extração de fósforo do solo pelo Tifton 85 e os teores de fósforo aumentam de forma mais expressiva com a aplicação de doses de fosfato de Araxá, sem alterara as demais características químicas do solo

Abstract:

La composition du tissu adipeux de porc est soumise a l'influence de nombreux facteurs. Nous avons considere particulierement la nature des lipides ingeres. L'effet du facteur nature des lipides ingeres a ete etudie sur des bardieres de deux cent seize porcs de race large white, nourris avec quatre regimes couvrant une large gamme d'insaturation. La composition en constituants essentiels du tissu apparait peu dependante de la nature des lipides ingeres. Par contre, la composition en acides gras de la bardiere et son domaine de fusion, determine par analyse enthalpique differentielle, lui sont relies etroitement. La transformation des tissus adipeux obtenus apres ingestion des differents regimes revele que le saucisson sec elabore avec le tissu adipeux le plus insature est juge inacceptable par le jury de degustateurs. Le manque de fermete du tissu entraine un defaut de sechage. Les reactions de fermentation se deroulent malgre tout normalement, comme l'indiquent les productions des acides (d) et (l) lactiques et acetiques en cours de fabrication. Secondairement, on a observe l'influence de la localisation anatomique des gras sur leur composition, et la qualite du saucisson sec en rapport avec l'acidification du produit. La premiere etude revele l'importance du facteur "localisation anatomique" sur les teneurs en eau, lipides, tissu conjonctif des tissus, determinantes sur la qualite des produits transformes. Le second travail souligne la contribution des acides (d) lactique au gout acide du saucisson, et acetique a l'odeur acide des gras extraits. Cependant, les causes d'un exces d'acidite sont sans doute multiples

Thesis (MA)--Stellenbosch University, 2012.
ENGLISH ABSTRACT: The aim of this research was to explore the interaction between governance and development in post-colonial Africa. The departure point of the thesis was the understanding that the state remains a pre-eminent actor in the international system. Keeping this assumption in mind, the study made use of a comparative analysis; comparing governance and development in Botswana with governance and development in Zaire/the Democratic Republic of the Congo (DRC), focusing on the post-colonial era. The importance of this research lies in its contribution to the debate on the role of the state in post-colonial Africa. It explores the influence of institution formation and policy implementation by governments (in other words, governance) on development. Understanding the effect of governance on development can have invaluable lessons for other African states in their efforts to develop further. The research question, which guided the thesis thus, was: in the era of the pre-eminence of the state, making use of a comparison between Botswana and Zaire/DRC, what is the influence and effect, of state institution formation and policy implementation (governance) by governments, on state development in terms of economical-, political- and social development? The two main variables were governance and development. Development was sub-divided into three indicators: political, economic and social development. Governance was evaluated in terms of being seen as poor or good governance, as per the World Bank’s definition and understanding of governance. Zaire/DRC, as an example of a failed state, was analysed first, followed by Botswana, selected for its arguably “best practice” experience. For each country the analysis was subdivided into three phases as per the theoretical framework of Chazan, Lewis, Mortimer, Rothchild, and Stedman’s book, Politics and Society in Contemporary Africa (1999). Their book describes three stages of change in African state development in the post-colonial era (Chazan-framework). This framework uses the Chazan-framework and thus subdivides the post-colonial era into: the concentration (centralisation) phase, the elaboration phase, and finally the reconsideration of state power phase. The research found that Zaire/DRC followed a process of state collapse in the post-colonial era, whereas in sharp contrast Botswana experienced positive state development. Since independence Zaire continuously practised poor governance whilst Botswana largely practiced good governance. This was true in all three phases of the Chazan-framework. At the same time, or perhaps due to poor governance, Zaire continuously experienced negative development in all three development categories whilst Botswana continuously experienced positive development in all three development categories, again perhaps due to good governance. The research concludes that even though Botswana is not necessarily an example of a perfect state, it is special in an African context, because of its good governance record. This study does not draw direct relationships between good governance and development, but finds that Botswana probably benefited greatly in development due to the implementation of good institutions, good government policies and general good governance. The research also found that states benefit when their governments practice and adopt policies that are anti-corruption, pro-democracy, pro-competition, pro public-private partnerships, and pro market-orientated economics. In addition, the following are also conducive to good governance: leadership with integrity, peaceful and regular leadership changes, clear distinction between government (party) and the state, and empowered government oversight institutions that act, even against the government itself when needed. The practice of good governance is thus shown to be supportive of long-term development.
AFRIKAANSE OPSOMMING: Die doel van hierdie navorsing was om die interaksie tussen regering en ontwikkeling in post-koloniale Afrika te ondersoek. Die tesis gaan uit vanuit die oogpunt dat die staat steeds ‘n dominante akteur in die internasionale stelsel is. Die studie het gebruik gemaak van ‘n vergelykende ontleding. Regeringstyl en ontwikkeling in post-koloniale Afrika is met mekaar vergelyk. Die vergelyking is getrek tussen Botswana en Zaïre/Demokratiese Republiek van die Kongo (DRK). Die belangrikheid van die navorsing lê in die bydrae tot die debat oor die rol van die staat in Afrika in die post-koloniale era. Dit bekyk die belangrikheid van instellingskepping en beleids-implementering (met ander woorde, regeerstyl of regering) deur regerings in terme van invloed op die ontwikkeling van state in Afrika. Beter begrip van hierdie verhouding kan waardevolle lesse bevat vir ander Afrikastate in hul pogings om verder te ontwikkel. Die navorsingsvraag wat die tesis gelei het was dus: in die era van die voorrang van die staat, en deur gebruikmaking van ‘n vergelykende studie tussen Botswana en Zaïre/DRK, wat is die invloed en effek van staatsinstelling-vorming en van beleids-implementering (regering) deur regerings, op staatsontwikkeling in terme van ekonomiese-, politieke- en sosiale ontwikkeling? In hierdie studie was regering en ontwikkeling die twee belangrikste veranderlikes gewees. Ontwikkeling is onderverdeel in drie aanwysers: politieke, ekonomiese en maatskaplike ontwikkeling. Regering is geëvalueer in terme van wat gesien word as swak of goeie regering, volgens die Wêreldbank se definisie en begrip van goeie regering. Zaïre/DRK is eerste as ‘n voorbeeld van 'n mislukte staat ontleed, gevolg deur Botswana, gekies vir sy veronderstelde "beste praktyk"-ervaring. Die analise vir elk van hierdie lande is onderverdeel in drie fases, soos gebaseer op die teoretiese raamwerk van Chazan, Lewis, Mortimer, Rothchild, en Stedman in, Politics and Society in Contemporary Africa (1999) (die Chazan-raamwerk). Hierdie raamwerk onderverdeel die post-koloniale era in: die konsentrasiefase (sentraliseringsfase), die uitbreidingsfase en uiteindelik die fase van die heroorweging van staatsmag. Die navorsing bevind dat Zaïre 'n proses van ineenstorting van die staat in die post-koloniale era ervaar het, terwyl Botswana in skrille kontras positiewe staatsontwikkeling ervaar het. Hierdie tendens was aanwesig in al drie fases van die Chazan-raamwerk. Sedert onafhanklikheid het Botswana ook goeie regering toegepas terwyl Zaïre/DRK meestal swak regering toegepas het. Terselfdertyd, dalk ook weens swak regering, het Zaïre/DRK voortdurend negatiewe ontwikkeling ervaar in al drie van die ontwikkelings kategorieë, terwyl Botswana voortdurend, moontlik te danke goeie regering, positiewe ontwikkeling in al drie die ontwikkelingskategorieë ervaar het. Die navorsing kom tot die gevolgtrekking dat, selfs al is Botswana nie noodwendig ‘n voorbeeld van 'n perfekte staat nie, dit steeds weens ‘n goeie regeringstradisie, uniek is in Afrika-konteks. Alhoewel hierdie studie nie 'n direkte verhouding tussen goeie regering en ontwikkeling probeer bevestig het nie, bevind dit wel dat Botswana moontlik in terme van ontwikkeling, weens die implementering van goeie instellings, goeie regeringsbeleid en algemene goeie regering, baie voordeel getrek het. Die navorsing bevind ook dat state voordeel trek wanneer hul regerings beleid aanvaar en toepas wat teen korrupsie is, maar wat demokratiese ideale, markkompetisie, openbare-private vennootskappe en markgeoriënteerde ekonomiese aktiwiteite bevorder. Goeie regering word ook bevorder deur leierskap met integriteit, vreedsame en gereelde verandering van leierskap, duidelike onderskeid tussen die regering (party) en die staat, sowel as nie-regeringsinstellings met die mag om as oorsigliggame oor die regering te funksioneer. Die praktyk van goeie regering blyk dus langtermyn staatsontwikkeling te bevoordeel en te ondersteun.

Abstract:

This work aimed to produce and to apply in dry fermented sausage a lactic acid starter culture using a pork plasma culture medium and to evaluate the effect of two levels (0.5% and 1%) of hydroalcoholic extract of marcela (Achyrocline satureioides) in the security and quality of dry fermented sausages. In the first experiment, the microorganism Lactobacillus plantarum was fermented with control of pH, during 36 hours, under continuous agitation of 100 rpm, at a temperature of 37 (± 0.1ºC). After entering in the stationary phase the culture was lyophilizated and applied in dry fermented sausage, evaluating its influence in the microbiological, physico-chemical and sensorial characteristics. For comparative effects, were elaborated treatments without addition of starter culture and with addition of a commercial culture. In the second experiment, dry fermented sausages had been elaborated with 0.5% and 1% of hydroalcoholic extract of marcela and without extract, considered as control. The parameters of pH, water activity, colour and weight loss were evaluated during the manufacture of the dry fermented sausages. During the storage the TBARS values were determined and verified the sensorial acceptance. The microorganism Lactobacillus plantarum had a maximum growth of 9.82 Log UFC.mL-1, after 30 hours of fermentation and it presented 90.05% of survival to the lyophilization. The dry fermented sausages elaborated with the starter culture produced had presented a decrease on pH significantly faster and a lower water activity than the others treatments. Moreover, the microorganism Lactobacillus plantarum improved significantly the flavor of the dry fermented sausages. The marcela extract addition decreased (p<0.05) the TBARS values during the storage of the dry fermented sausages, compared with the control. The treatment with 1% of marcela extract showed a bigger lipid stability than that with 0.5%, however it presented a reduction (p<0.05) in the sensorial acceptance. The two marcela extract levels had not influenced the parameters of pH, water activity, colour and weight loss. Therefore, this study indicated that the pork plasma culture medium is an alternative in the commercial production of lactic acid bacteria and that the starter culture produced provided a dry fermented sausage with greater microbiological security and better sensorial acceptance. The hydroalcoholic extract of marcela decreased the lipid oxidation and the concentration of 0.5% did not modify the sensorial characteristics, being able, therefore, to be used in the elaboration of safer dry fermented sausages to the consumers.
Este trabalho teve por objetivo produzir e aplicar em salame uma cultura starter ácido láctica utilizando um meio de cultura de plasma suíno e avaliar o efeito de dois níveis (0,5% e 1%) de extrato hidro-alcoólico de marcela (Achyrocline satureioides) na segurança e qualidade de salames. No primeiro experimento, o microrganismo Lactobacillus plantarum foi fermentado em um meio de cultura de plasma suíno, com controle de pH, durante 36 horas, sob agitação contínua a 100 rpm e temperatura de 37 (± 0,1ºC). Após entrar na fase estacionária a cultura foi liofilizada e aplicada em salame, avaliando sua influência nas características microbiológicas, físico-químicas e sensoriais. Para efeitos comparativos, foram elaborados tratamentos sem adição de cultura starter e com adição de uma cultura comercial. No segundo experimento, salames foram elaborados com 0,5% e 1% de extrato hidro-alcoólico de marcela e sem extrato, considerados como controle. Os parâmetros de pH, atividade de água, cor e perda de peso foram avaliados durante a fabricação dos salames. Durante o armazenamento os valores de TBARS foram determinados e foi verificada a aceitação sensorial. O microrganismo Lactobacillus plantarum teve um crescimento máximo de 9,82 Log UFC.mL-1, após 30 horas de fermentação e apresentou 90,05% de sobrevivência a liofilização. Os salames elaborados com a cultura starter produzida apresentaram uma queda de pH significativamente mais rápida e uma menor atividade de água que os demais tratamentos. Além disso, o microrganismo Lactobacillus plantarum significativamente melhorou o sabor dos salames. A adição de extrato de marcela diminuiu (p<0,05) os valores de TBARS durante o armazenamento dos salames, comparado ao controle. O tratamento com 1% de extrato de marcela mostrou uma maior estabilidade lipídica do que aquele com 0,5%, porém apresentou uma diminuição (p<0,05) na aceitação sensorial. Os dois níveis de extrato de marcela não influenciaram significativamente os parâmetros de pH, atividade de água, cor e perda de peso. Portanto, este estudo indicou que o meio de cultura de plasma suíno é uma alternativa na produção comercial de bactérias ácido lácticas e que a cultura starter produzida proporcionou salames de maior segurança microbiológica e melhor aceitação sensorial. O extrato hidro-alcoólico de marcela diminuiu a oxidação lipídica e a concentração de 0,5% não alterou as características sensoriais, podendo, portanto, ser utilizada na elaboração de salames mais seguros aos consumidores.

Abstract:

Para transmitir o torque gerado pelo motor de combustão interna para a caixa de transmissão por meio da embreagem, seja em automóveis ou caminhões, é necessário que haja contato por deslizamento entre um material polimérico multifásico e um contracorpo metálico de ferro fundido cinzento. Além disso, os níveis do coeficiente de atrito entre esses materiais têem que ser suficientemente alto e estável, para proporcionar uma transmissão de torque regular e eficiente. Porém, durante o deslizamento, materiais são transferidos de uma superfície para outra, e alterações microestruturais e fisico-químicas ocorrem. Como consequência, uma nova superfície (denominada de tribofilme) se desenvolve, influenciando o desempenho funcional da embreagem. Dessa forma, compreender as suas características tem se tornado essencial para desenvolver sistemas de embreagens cada vez mais eficientes. No entanto, muitos ensaios são necessários para que se possa entender como uma ou várias matérias primas se comportam em relação aos aspectos tribológicos. Isso faz com que surja a necessidade de repetir os ensaios inúmeras vezes, para que se façam as escolhas mais assertivas tanto das matérias primas quanto dos processos envolvidos. Como alternativa, para reduzir tempo e custos, e ter um maior controle sobre as variáveis de ensaio, busca-se simular em laboratório, com equipamentos mais simples, a reprodução das interações tribológicas em condições reais. A primeira fase deste trabalho tem como objetivo apresentar os mecanismos de desenvolvimento do tribofilme para três níveis de severidade em condições reais de aplicação (ensaios mais demorados, complexos e mais caros, devido à necessidade da confecção completa dos protótipos), e posteriormente correlacionar esses mecanismos com os que foram simulados por meio de ensaios conduzidos num tribômetro de laboratório do tipo pino-disco (ensaios mais rápidos e mais simples, consequentemente menos complexos), variando o PV de 3,08 até 11,08 MPa ms-1. Foi constatado que as características do tribofilme dependem da severidade da aplicação. Além do que, o tribômetro pino-disco (amostra de 13 mm de diâmetro externo) consegue reproduzir os mecanismos identificados em campo, pois houve paridade na transferência das características do tribossistema do modelo de ensaio para o da condição real (430 mm de diâmetro externo). Na segunda fase, diferentes séries de ensaios tribométricos foram realizadas para investigar a influência do tribossistema no desempenho funcional do par tribológico (atrito e desgaste). Para os ensaios tradicionais, foi constatada um aumento na taxa de desgaste para temperaturas superiores a 250°C, revelando uma transição no regime moderado de desgaste para o severo. Quando os debris de desgaste foram removidos do meio interfacial, o nível do coeficiente de atrito aumentou e a taxa de desgaste reduziu. Já a adição de debris de desgaste ao meio interfacial contribuiu para aumentar a taxa de desgaste e reduzir drasticamente o nível do coeficiente de atrito. No entanto, quando os ensaios foram realizados empregando discos pré-condicionados, a taxa de desgaste e o nível do coeficiente de atrito foram otimizados, principalmente em níveis de severidade mais elevados (PV 10,09 MPa ms-1) indicando potencial ganho na eficiência do sistema embreagem.
Torque from an internal combustion-engine to a gear box, either in automobiles or trucks, is transmitted by a clutch system. In order to transmit torque from one side to the other, sliding contact between a multiphase friction material and a gray iron rotor is necessary. Torque transmission depends on the friction level among the tribological couples, and it have to be relatively high and most importantly stable to allow an efficient and regular performance. During the sliding between the coupling surfaces, material is transferred from one surface to the other causing microstructure and chemical changes. As consequence, a new surface, also known as tribofilm, is developed. This surface governs the clutch system performance and understanding the tribofilm characteristics is very important to improve the development of efficient clutch systems. For this, a large number of tests are necessary to understand the tribological behavior of the raw materials. Such investigation is highly empirical and in order to have a consistent data it\'s necessary to carry out several friction tests repetitions. Alternatively, to save time and money, and have better control over the test variables, the real tribological interactions can be simulated in laboratory by using simple equipment, pin-on-disc tribometer. The simplicity of this device allows evaluating a larger number of alternative materials. The first part of this work aims to investigate the tribofilm development mechanisms in three severity levels on the field application (those tests are more time-consuming, complex and expensive, because it is necessary to produce the entire prototype), and then correlate these mechanisms with those simulated in a pin-on-disc tribometer (faster and simpler test) by changing the PV level from 3.08 to 11.08 MPa ms-1. It was found that the tribofilm characteristics depend on the severity of application. In addition, the pin-on-disc tribometer (sample of 13 mm outside diameter) can reproduce the same mechanisms that were identified on the field, due to the parity between the tribosystem characteristics of test model and field condition (430 mm external diameter). In the second part of this work, different series of tribometer tests were performed to investigate the influences of tribosystem on tribological couple performance (friction and wear). Standard tribometer tests presented an increasing in the wear rate at temperatures of 250°C, revealing a transition from moderate to severe wear regime. When wear debris were removed from the interfacial contact, the friction coefficient level increased and wear rate reduced. On the other hand, when the wear debris were added, it contributed to increase the wear rate and to reduce the friction level dramatically. However, when the experiments were performed by using pre-conditioned discs, the wear rate and friction coefficient level has been optimized, particularly at higher severity levels (PV 10.09 MPa ms-1).
