Pohlmann, Juliana Gonçalves. "Avaliação da reatividade ao CO2 de chars obtidos em atmosferas convenional (O2/N2) e de oxi-combustão (O2/CO2) com vistas à aplicação no alto-forno." reponame:Biblioteca Digital de Teses e Dissertações da UFRGS, 2010. http://hdl.handle.net/10183/27923.
Full textAbstract:
A injeção de carvão pulverizado - PCI - é praticada nas ventaneiras dos altos-fornos com o objetivo de substituir parcialmente o coque, provendo energia e gases redutores ao processo. Em geral, as melhorias desse processo ocorrem no sentido de diminuir o fuel rate e aumentar a produtividade do alto-forno. A tecnologia de oxi-combustão consiste na queima de carvão em uma atmosfera livre de N2, o qual é substituído por um gás rico em CO2. Visando a possibilidade de aplicação desta tecnologia em PCI, chars de três carvões de diferentes ranks utilizados para injeção e chars de um coque de petróleo foram obtidos em atmosferas convencional (O2/N2) e de oxi-combustão (O2/CO2) em forno de queda livre O objetivo do presente trabalho foi avaliar a reatividade ao CO2 desses chars por termogravimetria via método isotérmico a 1000°C. Resultados de eficiência da combustão (burnout), de área superficial e a morfologia dos chars antes da gaseificação auxiliaram a análise da reatividade. A reatividade foi, em geral, mais alta quanto mais baixo o rank do carvão e tendeu a aumentar com o burnout, o qual foi associado ao aumento na área superficial BET. Em geral, as reatividades ao CO2 dos chars de atmosferas O2/N2 e O2/CO2, obtidos com o mesmo teor de oxigênio, não apresentaram diferenças significativas. Apenas no caso dos chars do carvão de mais baixo rank e obtidos em maior teor de oxigênio é que as amostras de oxi-combustão foram mais reativas.Pulverized coal injection (PCI) is used in the blast furnace tuyeres attempting to provide energy and reducing gases to the process. New technologies have been studied to improve PCI and to make ironmaking process suitable to environmental requirements. Oxy-fuel combustion technology consists of burning coal in a N2-free atmosphere, which is exchanged by a CO2-rich gas. Aiming at a possible application of oxy-fuel combustion in blast furnace, chars of three typical PCI coals of different ranks were obtained under conventional (O2/N2) and oxy-fuel (O2/CO2) atmospheres in drop tube furnace. The aim of this work was to evaluate the CO2 reactivity of these chars via thermogravimetric analysis by isothermal method at 1000ºC. Coals burnouts, BET surface areas of chars and chars morphology before gasification gave support in the reactivity results analyse. In general, the higher reactivities were observed for the lower rank coal chars. Reactivity increased when coal burnouts and chars BET surface areas also increased. The CO2 reactivities of conventional and oxy-fuel chars, obtained under the same oxygen content, have not shown significant differences.

La problematique de cette these est celle du depassement de l'ambivalence a l'egard de la vie et du vivant, ceci face a la loi pascale du grain tombe en terre. Un parcours se dessine ici, du blaspheme a l'assentiment, qui ne voudrait rien eluder. L'avancee n'est pas rectiligne, le doute se maintient jusqu'au bout. Bien des etapes scandent la progression : proferer le non - et peut-etre deja le nom -, decouvrir le dieu revolte, vouloir "guerir", se rendre present, oser l'aveu, "mettre la main sur la bouche", se preceder par la parole et entrer dans le paradoxe, s'ejouir, s'ebouler et oser peser, choisir de "se laisser determiner" par dieu. Le mouvement de bascule decisif du non au oui correspond a la substitution, dans cette oeuvre tournant qu'est jacob, de la preposition "vers" a la preposition "contre" attendue dans le groupe nominal : "contestation incessante vers toi"The problem dealt with in this thesis is that of transcending the ambivalence of life and living and this, in the context of paschal law of the grain falling to earth. A trajectory is outlined here, from blasphemy to consent, that doesn't attempt to evade anything. Progress is not linear, doubt is maintained to the end. Many stages the progression : to utter the name - and maybe already the name -, to discover the rebellious god, to desire "to heal", to make oneself present, to dare to confess, to "put one's hand on one's mouth", to precede oneself in speech and enter into paradox, to rejoice, to collapse and dare to weigh, to choose to "allow oneself to be determined" by god. The decisive movement of swinging from "no" to "yes" corresponds to the substitution in jacob, that key work, of the preposition "vers" ("towards") in place of the expected preposition "contre" ("against") in the nominal phrase : "incessant dispute with ("vers") you"

Full textAbstract:
Cloud computing is a quickly growing field in modern computing science where new technologies arise every day. One of the latest trends in cloud computing is container based technology, which allows applications to run in a reproducible and stateless fashion without requiring manually installed dependencies. Another trend in computer science is DevOps, a methodology where developers take part in the operations process. DevOps popularise the use of CI/CD workflows, where automatic pipelines run tests and scripts on new code. A container orchestrator, like Kubernetes, can be used to control and modify containers. Kubernetes allows integrating multiple third-party applications that can monitor performance, analyze logs, and much more. Kubernetes can be integrated into the CI/CD system to utilise its container orchestration perks. Building containers inside a container can cause security issues because of native security flaws with OCI build tools. This thesis aims to look at these issues and analyse the field of container orchestrated OCI build tools using Kubernetes and OCI build tools. We also discover how to develop a test suite that can reliably test container orchestrated OCI build tools and export metrics. The thesis lastly compares different Dockerfile compliant Build tools with the test suite to find out which has the best performance and caching. The compared build tools are BuildKit, Kaniko, Img and Buildah and overall BuildKit and Kaniko are the fastest and most resource effective build tools. It is not obvious which build tool that is the most secure. Kaniko, which is a root container requires no privileges and is therefore tough to break out of but an eventual breakout will give the attacker root access to the host machine. BuildKit and Img only requires unconfined SECcomp and AppArmor which will make a container breakout more probable, even though less than Buildah which must be run in a privileged container. Since they can run rootless, the attacker will only have the same access to the host as that user in case of a container breakout.

Full textAbstract:
This thesis is a sociolinguistic study that addresses the link between M��ori identity and the
ability to speak and understand te reo M��ori (the M��ori language). This study goes right to
the heart of the relationship between language and identity. The international literature
regarding this relationship is considerable and suggests that for many of the indigenous and
minority language communities around the world, such a link is an imperative. It is a view
that is also reflected in the M��ori literature. As a first step this study questions that
proposition and explores the views of M��ori on this matter which allows us to gain insights
into the ways in which M��ori in the early 21st century view their language and their identity.
In a second phase this study looks to explore the idea of encouraging and supporting non-
M��ori ��� those who have no M��ori whakapapa (geneology) ��� into learning to speak te reo
M��ori as a means of assisting te reo revitalisation, through increasing the numbers of
speakers of te reo. Understandings around the importance of te reo to M��ori identity have had
a huge influence on the ways in which M��ori reacted to this proposition.
This project is of direct relevance to M��ori, who have been extremely concerned for several
decades about the loss of the M��ori language and its ongoing threatened status. M��ori have
been directly involved in measures to preserve the language both on the national stage and at
local levels. More than 600 people contributed to this study and both quantitative and
qualitative modes of analysis were employed at different stages of this study. The quantitative
data from the survey was analysed using the SPSS1 programme. Interpretive content analysis
and narrative analysis that utilised tikanga or models of M��ori understandings of identity, and
sociolinguistic theory exposed a number of themes that are used to illustrate the findings of
this study.

Full textAbstract:
Notre thèse s'inscrit dans le cadre de l'étude des relations non gouvernementales franco-vietnamiennes. Elle porte sur l'évaluation des Organisations de solidarité internationales françaises (OSI), acteurs majeurs engagées en grand nombre dans l'action humanitaire, ainsi que dans beaucoup d'autres domaines, pour l'aide au développement du Vietnam, et ce, dès les années 1975. Dans un premier temps, elle prend en considération leurs différents aspects : leurs origines, leurs structures, leurs moyens, leurs pratiques, leurs conditions de travail, leurs modes d'intervention au siège comme sur le terrain. Dans un deuxième temps, elle propose, à l'appui des recherches sur leur diversité et leurs interventions, une réflexion sur les problèmes qui les concernent :les atouts qu'elles possèdent sur les autres acteurs, les faiblesses qui limitent leurs actions, les rapports qu'elles entretiennent avec les différents partenaires, les rôles qu'elles jouent dans l'accompagnement des politiques sociales. Notre objectif étant de mettre un éclairage sur les facteurs qui constituent et affectent ce monde, de montrer dans leur fonctionnement, comment ces organisations arrivent à atteindre leurs objectifs dans un contexte spécifique d'un pays en voie de développement fortement marqué par la mainmise de l'Etat Parti et par la présence d'un grand nombre d'acteurs internationaux. Plus de 300 de OSI françaises intervenant au Vietnam constitue un phénomène impressionnant Leur contribution à la promotion des relations franco-vietnamiennes est indéniable. Cependant, ce monde fort motivé et compétent souffre encore d'une insuffisance d'attention de la part des protagonistes des deux pays. De nombreux progrès restent encore à réaliser dans le rapprochement entre leurs pouvoirs publics respectifs et les acteurs non gouvernementaux pour rendre l'aide française plus efficace et donner une image exemplaire des relations de coopération entre un pays développé et un pays en voie de développementThis research is formally classified as a study of Franco-Vietnarnese non governmental relations. It deals with the evaluation of the French non-governmental organisations (OSI), one of the major contributors who has significantly invested in Vietnam as well as in many humanitarian endeavours to aid in the development since 1975. On one level, it takes into consideration these various aspects: origin, structure, resources, practices, employment conditions, and modes of intervention at the national office as well as in the field. On the other level, it indicates gratitude for the diversity study and the implemented actions taken. It also indicates the assets they have above other participants, the weaknesses that limit theirs actions, the relations they have established with other partners, and the role they play in instituting social policies for the country. The objective is to clarify the factors that constitute and affect this community, and to indicate how they can obtain the objective of thejr function in the particular Vietnamese context marked by the seizure of a Party Government and the presence of a great number of international actors. Over 300 French NGOs working in Vietnam is an impressive phenomenon. Their contribution to the promotion of Franco-Vietnamese relations is undeniable, However, this motivated and competent community has suffered from jnsufficient attention from the political protagonists of the two countries. There are many things that can be done by both the public authorities and the non governmental organisations to make French help more efficient and to give an exemplary image of the cooperation between a developed country and a developing one

Full textAbstract:
Introducció: El càncer colorectal és un dels càncers més freqüentes del nostre país així com en la majoria de societats occidentals. Els factors mebiambientals juguen un paper determinant en el seu desenvolupament. Els nutrients i específicament els greixos, estarien entre els factors més destacats.Tot i que a Groenlàndia, Finlàndia i algunes zones mediterrànies, les dietes tenen un alt contingut en greix, la incidència de càncer colorrectal és relativament baixa en comparació amb la resta de països occidentals. Una important diferència dietètica és l'elevat consum de peix i oli de peix (ric en els àcids grassos n-3, eicosapentaeonic (EPA) i docosahexaenoic (DHA)) en el cas del països nòrdics i l'oli de oliva (ric en àcid oleic C18:1, n-9) a la conca mediterrània.
La tesi es basa en la hipòtesi que "l'oli de peix i el d'oliva són capaços de modular el desenvolupament del càncer colorrectal.
Objectius: L'objectiu de l'estudi va ser avaluar els mecanismes pels quals aquests olis realitzaven aquesta modulació i la implicació dels àcids grassos presents en aquests.
Resultats: Per respondre els objectius plantejats es van utilitzar dues estratègies d'estudi. La primera es basa en estudis in vitro amb línies cel·lulars d'adenocarcinoma colorectal, Caco-2 i Ht-29. L'altra es basa en l'estudi de l'efecte dels diferents nutrients en un model animal d'inducció de la carcinogènesi colorectal.
L'oli de peix i l'oli d'oliva indueixen la diferenciació en cèl·lules Caco-2. Com a resultat de la diferenciació aquestes cèl·lules comencen a expressar els enzims Sucrasa-Isomaltasa i la Dipeptidilpeptidasa IV.
La regulació de l'homeòstasi del teixit colònic depèn d'una estreta relació entre la proliferació cel·lular i l'apoptosi o mort cel·lular programada
Mitjançant estudis d'incorporació de timidina tritiada, hem demostrat que l'oli de peix té un important efecte inhibidor de la proliferació de les cèl·lules Caco-2 i HT-29. Sembla ser, que aquests efectes són deguts als àcids grassos n-3 EPA i DHA presents en l'oli de peix. L' efecte modulador del desenvolupament del càncer colorectal per part de l'oli de peix i del d'oliva té la seva major incidència en la inducció de l'apoptosi. L'índex d'apoptosi s'ha determinat analitzant els canvis morfològics de les cèl·lules (amb tinció DAPI). L'oli de peix, l'oli d'oliva, així com el DHA, l'EPA i l'àcid oleic són capaços d'incrementar l'apoptosi de forma molt significativa. Aquests efectes estan relacionats amb una molt ràpida inhibició de l'expressió de COX-2. L'expressió de la proteïna antipopotòtica Bcl-2 disminueix després de disminuir COX-2, fet que suggereix la implicació d'aquests dos gens en els efectes antineoplàstics produïts per aquests àcids grassos. Per altra banda es va demostrar una clara implicació de la proteïna pro-apoptòtica BAX, ja que a l'administrar un inhibidor d'aquesta, es produïa una disminució significativa de l'apoptosi.
L'oli de peix i el d'oliva tenen un important efecte protector en la inducció de la carcinogènesi colorectal en animals tractats amb azoximetà. Els animals que van rebre una dieta amb oli de peix o d'oliva, com a font principal de greix, presentaven un major índex d'apoptosi. Per altra banda, l'oli de peix podria tenir un efecte preventiu al ser capaç d'incidir en la renovació de l'epiteli sa, incrementant l'apoptosi d'aquestes cèl·lules.
Conclusions: L'oli de peix és capaç de modular de forma clara el desenvolupament del càncer colorectal incidint directament en els processos de diferenciació cel·lular, proliferació i apoptosi. L'oli de peix podria tenir un efecte preventiu del desenvolupament del càncer colorrectal al modificar la regeneració de l'epiteli colònic sa. L'oli d'oliva pot modular el desenvolupament del càncer colorrectal encara que no tingui el seu efecte en la totalitat dels mecanismes estudiats.
Introduction: Colorectal cancer is one of the most frequent cancers in our country as well as in most of the occidental societies. Environmental factors play a crucial role on its development. Nutrients and in concrete fat seems to be one of the most determinant components. Although relatively high fat diets are consumed in Greenland, Finland and some Mediterranean areas, colorectal cancer incidence remains relatively low there. An important difference between these regions and the rest of the western countries is the much higher consumption of fish and fish oil (rich in the n-3 fatty acids eicosapentaenoic, C20:5 and docosahexaenoic, C22:6) in the case of the Northern countries, and fish and olive oil (containing mostly oleic acid, C18:1, n-9) down in the Mediterranean basin.
The hypothesis of our study was if "fish oil and olive oil are able to modulate the colorectal cancer development".
Aims: The objectives of this study were to evaluate the mechanisms implicated in the modulation of cancer by these oils and determine the implications of its fatty acids.
Results: In order to answer the objectives mentioned above we followed two study strategies. First, we performed: in vitro studies using adenocarcinoma cell lines, Caco-2 and Ht-29. The other one is the study of the effects of several nutrients in an animal model of carcinogenesis induction .
Fish oil and olive oil induced the differentiation of Caco-2 cells. As a result of this differentiation, the cells began to express Sucrase-Isomaltase and Dipeptydilpeptidase IV enzymes.
Homeostasis regulation of colonic tissue depends on a tightly relationship between cell proliferation and cell loss, through apoptosis.
With [3H] thymidine incorporation studies, we demonstrated that fish oil has an important inhibitor effect on the proliferation of Caco-2 and HT-29 cells. It seems that this effect is caused by EPA i DHA (n-3 fatty acids present in fish oil). The most important effect on the development of colorectal cancer by fish oil and olive oil is the induction of apoptosis. To determine the Apoptotic index we evaluated cell morphologic changes by DAPI staining.
Fish oil, olive oil, as well as DHA, EPA and oleic acid are able to increase apoptosis in a significant manner. These effects are related to a very fast inhibition of the expression of COX-2. Antipoptotic Bcl-2 protein expression decreases after Cox-2 expression inhibition, suggesting that these two genes are implicated in the antineoplastic effects. On the other hand, we demonstrated a clear implication of the proapoptotic protein BAX, because when an inhibitor of BAX was added, apoptosis significantly decreased.
Fish oil and olive oil have an important protective effect in the induction of colorectal carcinogenesis in animals which received an azoximethane treatment. Animals fed with fish oil and olive oil as a principal source of fatty acids in its diet, showed a higher apoptotic index. On the other hand, fish oil may have a preventive effect due to an acceleration of the turnover of colonic epithelia through the induction of apoptosis of these cells.
Conclusions: Fish oil can modulate the development of colorectal cancer in cellular differentiation, proliferation and apoptosis processes. Fish oil could have a preventive effect on the development of colorectal cancer modifying the regeneration of normal colonic epithelial. Olive oil could modulate the development of colorectal cancer although not having effects in all of the studied mechanisms.

Full textAbstract:
Omi/HtrA2 is a mitochondrial serine protease with high homology to the bacterial HtrA proteins. Omi promotes caspase-dependent apoptosis by binding and degrading IAPs-inhibitor of apoptosis proteins. Omi can also induce caspase-independent apoptosis but the actual mechanism is still unknown. IAP's are not the only substrates cleaved by Omi. There are at least two more known substrates of Omi, the HAX-1 and the ped/pea-15 proteins. HS1-associated protein X-1 (HAX-1) is a mitochondrial protein, degraded by Omi after induction of caspase-dependent apoptosis. Ped/pea-15 is also an anti-apoptotic protein and is cleaved by Omi after induction of caspase-independent apoptosis. The proteolytic activity of Omi is necessary and essential for its pro-apoptotic function. Recent studies suggest the proteolytic activity of Omi is regulated by specific protein-protein interactions. Presenilin was identified to be such a regulator of Omi. It binds to the PDZ domain of Omi via its carboxy-terminus and this interaction significantly increases the proteolytic activity of the enzyme. My project was aimed to investigate the normal function of Omi in cell death and the mechanism of its regulation by isolating and characterizing novel Omi interactors. I screened a human melanocyte cDNA library using the yeast-two-hybrid system and Omi as the "bait" protein. Human Rad21 protein was isolated as a specific novel interactor of Omi. Human Rad21 interacted with the PDZ domain of Omi, the part of the protein known to be involved in protein-protein interactions. Human Rad21 is a nuclear protein that plays a role in DNA double-strand break repair and sister chromatid cohesion during metaphase. Several reports suggest hRad21 has also a role in apoptosis; it is cleaved by caspase-3 and part of the protein becomes cytoplasmic. Human Rad21 was not cleaved by Omi in vitro and therefore it is unlikely to be a substrate. When tested in a proteolytic assay Rad21 was able to increase the proteolytic activity of Omi. My work suggests a new mechanism whereby Omi and hRad21 can co-operate to induce cell death. This mechanism necessitates direct interaction of hRad21 with the PDZ domain of Omi resulting in increased proteolytic activity of the enzyme.M.S.

Full textAbstract:
This master’s thesis suggests that Oi! - lyrically – gives voice to a youth community whose identity lies in everyday working class life. The identity in question is based upon class, gender, sexuality, nationality, and community awareness. As these are intertwined, the thesis shows a more complex genre than that of Matthew Worley’s “Oi! Oi! Oi!: Class, Locality, and British punk”. On the other hand, using the above categories - derived from the studies of Kathryn Woodward – allows this essay to detect a genre identity made from a distinct “the Same” and “the Other” – us and them, as described by Stuart Hall. The latter consists of members of the middle and upper classes along with all kinds of intellectuals. “The Same” is based upon a common belonging to the working class and its local communities, but also on nationhood. On the contrary, the male gender in general and the male sexuality in particular adds to the idea of Oi!´s “the Same”. In contrast to the idea of “the Same”, Stephen Greenblatt’s idea of dissonance works to explain cracks in the façade of Oi! as explained in the spatiotemporal discourse. Moreover, Oi!’s “the Same” is quite alike the subaltern of Antonio Gramsci. This concept suggests that the members of the proletariat are too unaware to be ideologically enlightened and therefore their culture expresses the way of working class life as it is, complete with eventual moral flaws. Whereas Gramsci uses the subaltern as a description of the rural proletariat of southern Italy and suggests folklore as the cultural outcome of that particular discourse, this essay aims to use it similarly but with Britain of the 1980’s and Oi! at its focal point. Furthermore, this essay describes the “Circuit of Culture” - as explained by Woodward - and puts Oi! into that model, which enables an understanding of the genre as an expression of produced, consumed, regulated, and represented identity. In conclusion, this master’s thesis do not refute Worley´s description of Oi! as a socioeconomic product, but rather adds to that by intertwining Woodward´s categories. The intersectional understanding of Oi! states that class, gender, community, sex, and nationality work together to create a genre, which represents a Gramscian subalternative proletariat. However, Hall’s “the Other” makes it perfectly clear that there is a distinct gap between Oi! and white power-music, which is also proved - throughout the essay - by the two genres regard to whiteness studies.

Full textAbstract:
The increases in communication bandwidth provided by fiber optics and high-speed switching technologies have shifted the limiting factor in data throughput from the communication
link to the communication processing. The communication processing for open systems interconnection (OSI) in particular is quite heavy due to the inclusion of data transfer syntax conversion in order to assure interoperability between different machine
types. In this thesis report, two multiprocessing architectures are considered as protocol processing engines for OSI communications.
The conventional approach is to have the host computer perform the protocol processing
especially for the higher layers. However, the protocol processing burden at communication rates of hundreds or even thousands of million bits per second places such a heavy processing burden on the host that this becomes undesirable. The protocol processing engines act as front-end systems performing most of the OSI protocol processing,
including the transfer syntax conversion, on behalf of the host. A multiprocessor approach was selected because the required amount of processing power can be supplied using lower processor technology than for an uniprocessor approach.
The protocol engines were designed based on a processing model in which different packets are processed at the same time in different processors. The protocol engines are designed to perform the protocol processing for OSI layers 2 through 6. Results obtained from simulating the designs indicate that a processing throughput of a hundred megabit per second is achievable only for packets which contain very simple data structures.Applied Science, Faculty of

A publicação de trabalhos científicos é uma das principais formas de avanço da Ciência, dando aos autores o reconhecimento de seu trabalho por parte da comunidade científica. A divulgação de trabalhos publicados é de grande interesse tanto da parte de quem os desenvolve (autores), quanto de quem pode vir a se beneficiar dos resultados (a comunidade científica em geral). Neste contexto, as bibliotecas digitais surgem como uma alternativa para simplificar o processo de publicação de artigos. Nelas encontram-se repositórios de dados que possuem informações sobre os artigos publicados bem como links para os próprios artigos, ou mesmo os arquivos propriamente ditos. Dois pontos importantes na implementação e uso de bibliotecas digitais são a interoperabilidade e a padronização dos metadados que serão utilizados pelos repositórios. Essas questões podem ser resolvidas através da OAI (Open Archives Initiative) e pelo formato Dublin Core. Um exemplo de biblioteca digital que utiliza o padrão OAI é a BDBComp (Biblioteca Digital Brasileira de Computação), que disponibiliza os metadados sobre os artigos publicados nos eventos de computação no Brasil. Por outro lado, a SBC (Sociedade Brasileira de Computação) disponibiliza aos eventos que promove (e atualmente também a alguns eventos internacionais) o sistema JEMS para o gerenciamento das submissões dos artigos. Através dele os artigos são avaliados, e é feita a seleção daqueles que serão publicados em cada evento ou periódico que utiliza o sistema. Neste trabalho é apresentado um serviço de geração de metadados compatível com o padrão OAI, desenvolvido para disponibilizar os metadados sobre os artigos publicados nas conferências ou periódicos que utilizem o JEMS. Os metadados gerados são disponibilizados para bibliotecas digitais, como a BDBComp. O serviço é de fato um provedor de dados OAI, que utiliza dados provenientes do sistema JEMS e os disponibiliza no formato Dublin Core a bibliotecas digitais através do protocolo OAI-PMH, o qual é baseado em XML. Este provedor de dados foi desenvolvido para uso com a biblioteca digital da SBC, e oferece um aumento da quantidade e da qualidade dos metadados disponibilizados sobre os artigos publicados nos eventos e periódicos gerenciados pelo JEMS.The publication of scientific works is one of the greatest forms of Science progress, giving the authors recognition from scientific community about their work. The publication spreading is of great interest for both the authors and those that can be benefited from the results. In this context, the digital libraries appear as an alternative to simplify the paper publication process. They own data repositories that have information about published papers as well as links for the papers. Two important points in the implementation and use of digital libraries are metadata interoperability and metadata standadization. These questions can be solved by the OAI (Open Archives Initiative) and by the Dublin Core format. An example of digital library that uses the OAI standard is BDBComp (Biblioteca Digital Brasileira de Computação), which have metadata about papers published in computing science events in Brazil. On the other hand, SBC (Sociedade Brasileira de Computação) have the JEMS system for use in the management of paper submission for the events that SBC promotes (and nowadays for some international events too). Through JEMS the papers are evaluated, and a selection of the accepted papers can be done. This work presents an OAI-compatible metadata generation service developed to offer metadata about the papers published in conferences or journals that use JEMS. The generated metadata are made available to digital libraries, like BDBComp. The service is in fact an OAI data provider that uses data obtained from JEMS and offer the metadata in the Dublin Core format to digital libraries, through the OAI-PMH protocol, which is based on XML. This data provider was developed for use with the SBC’s digital library. It gives an improvement on the quantity and quality of the available metadata about the papers published by the events and journals managed by JEMS.

O objetivo do presente projeto foi traduzir e adaptar para o português do Brasil as escalas Obsessive-Compulsive Inventory (OCI) e Obsessive-Compulsive Inventory-Revised (OCI-R) e avaliar as propriedades psicométricas do instrumento OCI-R, o qual avalia a gravidade dos sintomas obsessivo-compulsivos. O projeto foi desenvolvido em duas etapas: (1) a tradução, a adaptação transcultural e a retrotradução das escalas e (2) o estudo de confiabilidade e validade do questionário OCI-R em uma população clínica e em uma amostra não-clínica. Essas escalas têm como vantagem em relação as já existentes o fato de serem autorespondidas e de produzirem escores para categorias específicas de sintomas obsessivocompulsivos. Na primeira fase, a OCI e OCI-R, desenvolvidos no Centro para o Tratamento e Estudo de Ansiedade da Universidade da Pensilvânia, EUA foram traduzidas e a adaptadas para a língua portuguesa. As escalas foram inicialmente traduzidas para o português por dois psiquiatras bilíngües e retrotraduzidas por outros dois psiquiatras bilíngües de forma independente e em seguida, aplicadas em 15 portadores do Transtorno Obsessivo Compulsivo (TOC) com diferente escolaridade e intencionalmente selecionados para efetuar ajustes na linguagem. A versão final das escalas OCI e OCI-R foram aceitas pelo autor após o processo de retrotradução destas. As escalas mostraram-se de fácil compreensão e preenchimento pelos pacientes, podendo ser utilizadas em pacientes com TOC de diferentes classes econômicas e sociais. As escalas OCI e OCI-R, em suas versões adaptadas para o português do Brasil poderão auxiliar os profissionais de saúde no rastreamento de possíveis portadores de TOC e na avaliação da intensidade dos sintomas obsessivos compulsivos em pesquisa, e sua redução com diferentes métodos de tratamento. A tradução e a adaptação serão apresentadas no artigo nº. 1. A segunda etapa do projeto avaliou as propriedades psicométricas da versão brasileira da OCI-R em uma população clínica e em uma não clínica (controle). A validade e confiabilidade da versão para o Português do Brasil da escala Obsessive–Compulsive Inventory-Revised (OCI-R) foram examinadas em uma amostra clínica de 64 pacientes com Transtorno Obsessivo-Compulsivo (TOC), 33 pacientes com Fobia Social, 33 pacientes com Transtorno do Pânico e em uma amostra não clínica de 130 funcionários de um hospital geral. Foi verificado que as subescalas da OCI-R discriminam e avaliam a gravidade dos seis subtipos de sintomas de TOC. A confiabilidade teste-reteste foi examinada usando os dados dos 64 pacientes com TOC que completaram a OCI-R em dois diferentes momentos. Em cada amostra o escore total e os escores das subescalas demonstraram consistência interna de moderada a boa e boa validade concorrente e discriminante. Além disso, demonstrou ser sensível aos efeitos do tratamento cognitivo-comportamental em grupo. Nossos achados sugerem que a versão para o Português do Brasil da OCI-R mantêm as propriedades psicométricas da versão original. Os resultados foram comparados com os dados das versões da OCI-R em Espanhol e Alemão. Essa fase será apresentada no artigo nº. 2. A utilização da OCI-R em sua versão em português do Brasil poderá auxiliar os profissionais de saúde e os pacientes na triagem de pessoas com suspeita de TOC. Mais do que isto, seu uso poderá identificar os portadores de TOC clínico ou subclínico. Por se tratar de uma escala auto-respondida, facilita o conhecimento da doença mais cedo, o que é relevante, visto que os pacientes levam muitos anos para procurar tratamento para o TOC. Adicionalmente, ao empregarmos este instrumento, poderemos desenvolver e incrementar programas de prevenção e educação, assim como concentrar esforços nas ações de intervenção.The aim of the present project was to translate and adapt the scales Obsessive- Compulsive Inventory (OCI) and Obsessive-Compulsive Inventory-Revised (OCI-R) to Brazilian Portuguese and to evaluate the psychometric properties of the OCI-R, which measures the severity of the obsessive-compulsive symptoms. The project was developed in two stages: (1) the translation, transcultural adaptation and back-translation of the scales and (2) the study of reliability and validity of the questionnaire OCI-R in a clinical population and in a non-clinical sample (controls). The advantages of those scales, compared to the existent ones, are: (a) they are selfreported and (b) they produce scores for specific categories of obsessive-compulsive symptoms. In the first stage, the OCI and OCI-R, developed by the Center for the Treatment and Study of Anxiety, University of Pennsylvania, EUA were translated and adapted to the Brazilian Portuguese language. The scales were initially translated into Brazilian Portuguese by two bilingual psychiatrists and then independently back-translated by other two bilingual psychiatrists. The scales were then applied to 15 Obsessive Compulsive Disorder (OCD) patients, deliberately chosen from different educational levels, to make language adjustments. The author accepted the final version of the OCI and OCI-R scales after their back translation. Scales showed to be easy to understand and fill in by individuals and may be used with OCD patients of different socioeconomic levels. The OCI e OCI-R scales, in their version adapted to Brazilian Portuguese, can help health professionals in screening potential OCD patients assess the severity of obsessive-compulsive symptoms and the reduction of them through different treatments. The translation and the adaptation will be reported in the paper nº. 1. The second stage of the project evaluated the psychometric properties of the Brazilian version of the OCI-R in a clinical and in a non- clinical (controls) samples. The reliability and validity of the Brazilian Portuguese version of the Obsessive–Compulsive Inventory – Revised (OCI-R) were examined in a clinical sample of 64 patients with Obsessive- Compulsive Disorder (OCD), 33 patients with Social Phobia and 33 patients with Panic Disorder plus a non-clinical sample of 130 employees of a general hospital. Results indicate that the OCI-R is a valid measure for identifying and assessing the severity of the six symptom subtypes of OCD. In each sample the overall and subscale scores demonstrated moderate to good internal consistency and good convergent and divergent validity. Furthermore, in patients with OCD, the inventory showed sensitivity to Cognitive-Behavioral Group Therapy (CBGT). Our findings indicate that the Brazilian Portuguese version of the OCI-R retains the psychometric properties of its original version. These results were also compared with the results of validation of the Spanish and German OCI-R versions. That phase will be reported in the paper nº. 2. The OCI-R Brazilian Portuguese version can help health professionals and patients to screen potential people with OCD. More than this, its use can identify clinical or sub clinical OCD patients. As it is a self-report scale, it facilitates the early awareness of the disease, which is relevant because patients may take several years to seek treatment for OCD. Moreover, the use of this instrument can help to develop educational programs which could ameliorate prevention, as well as focus efforts in intervention actions.

Full textAbstract:
Eine depressive Erkrankung kann sich mit unterschiedlicher Geschwindigkeit innerhalb weniger Stunden oder über Monate hinweg ausbilden. Zur Erfassung dieses bisher wenig untersuchten klinischen Merkmals wurde das Onset of Depression Inventory (ODI), ein standardisiertes klinisches Interview, entwickelt. Die vorliegende Studie prüfte die Test-Retest-Reliabilität des Onset of Depression Inventory und betrachtete die Frage nach dem optimalen Zeitpunkt der Durchführung des Interviews im Krankheitsverlauf. Es konnte gezeigt werden, dass die Patientenangaben zur Geschwindigkeit des Depressionsbeginns über den Beobachtungszeitraum zwischen zwei Untersuchungszeitpunkten stabil sind und auf hohem Niveau signifikant korrelieren. Im Weiteren zeigte sich keine Beeinflussung der Angaben zur Geschwindigkeit des Depressionsbeginns durch die Schwere der depressiven Symptomatik. Die hohe Übereinstimmung der Patientenangaben resultiert in einer hohen Test-Retest-Reliabilität und spricht für die Verlässlichkeit der mit dem ODI erhobenen Daten. Damit ist mit dem ODI ein geeignetes Instrument für die reliable Erfassung der Geschwindigkeit des Depressionsbeginns gegeben, was gleichermaßen für die klinische Arbeit als auch für wissenschaftliche Zwecke anwendbar ist und vor allem im klinischen Kontext eine frühe Differenzierung zwischen Unipolarer Depression und Bipolarer Affektiver Störung ermöglicht.

Gli oli essenziali sono miscele naturali di composti volatili ottenute per distillazione di parti aree della pianta. Tra i più ricercati oli essenziali c’è anche quello di geranio, prodotto ricavato dalle foglie delle piante appartenenti al genere Pelargonium. Lo scopo di questa tesi è stato quello di individuare e valutare i principali descrittori sensoriali, in grado di caratterizzare i campioni di olio essenziale di geranio provenienti da diverse aree geografiche: Madagascar, Isola di Rèunion, Egitto e Cina. L’applicazione dell’analisi quantitativa-descrittiva QDA®, ha permesso di individuare sei attributi in grado di descrivere e soprattutto discriminare i campioni. Nell’intento di aiutare gli assaggiatori a sviluppare una terminologia appropriata e a valutare le intensità dei descrittori scelti su scale di misura, sono stati inoltre definiti degli standard di riferimento di supporto alla valutazione olfattiva. L'elaborazione statistica dei dati sensoriali mediante analisi di varianza ha evidenziato come gli attributi fiori freschi, citronella e fiori macerati siano quelli dotati di maggior capacità discriminante anche se non è stato possibile differenziare i campioni in funzione dell’origine geografica. Gli attributi selezionati attraverso la QDA® sono stati scelti in modo da risultare particolarmente caratterizzanti e di facile comprensione. Attraverso un lavoro di elaborazione anche semantica potrebbero essere utilizzati dalle aziende produttrici come leve per il supporto al marketing e come spunto per promuovere il prodotto, differenziarlo rispetto ai concorrenti oppure per un possibile miglioramento tecnologico e sensoriale del prodotto.

The Open Systems Interconnection Passive Monitor (OSI-PM), which is based on the principles of the OSI-Reference Model (OSI-RM), provides a framework for the development
of multi-layer passive monitoring and testing. It adopts the same seven-layer architecture of the OSI-RM and provides the capability of selectively displaying, capturing,
and analyzing the protocol events on single or multiple connections for any subset or all of the seven layers. Different from conventional monitors, the OSI-PM is able to detect protocol violation as they occur in addition to the monitoring functions. The current OSI-PM is able to monitor and test up to the transport layer of the OSI-RM. This thesis discusses the design, prototype implementation and testing of the OSI-PM.Science, Faculty of

This master thesis examines the development of the two earlier independent IR protocols Z39.50 and SR (Search and Retrieve, ISO 10162/10163), now Z39.50/SR, from the beginning of the 80s to 1996 and their functionality in the client/server environment. Z39.50 applications in library systems will allow easy access to information regardless of platform or location. The use of Z39.50 will create a new user environment. Almost all the library systems of the market support the Z39.50 and surprisingly the use of it in Sweden lied on a very low leve! in 1996. This thesis was followed-up by an interview and a questioner among the Swedish Z39.50 users. They could see a huge potential of development concerning the future IR process. Z39.50 will change the libraries' traditional IR structure and the behaviour of the end-users.

D'abord, un logiciel portable de communications osi pour un reseau local est presente ou les aspects de portabilite et de flexibilite sont soulignes. Ce logiciel est structure en modules afin d'assurer sa flexibilite pour l'ajout de nouveaux protocoles et l'adaptation aux reseaux multiples. L'environnement de developpement de protocoles est d'abord introduit, puis plus particulierement la couche session et l'interface utilisateur sont presentes. Le deuxieme projet concerne le terminal rnis-osi. Pour certains teleservices, le reseau du rnis ne represente que les trois premieres couches selon l'architecture osi et les teleservices correspondent aux applications du niveau 7. Afin d'assurer ce type de teleservices, l'architecture du rnis doit comporter les protocoles rnis ainsi qu'un ensemble de protocoles osi. Une coordination entre les protocoles d'osi et ceux du rnis devient alors necessaire. Cela nous a conduit a la conception d'une couche commune reseau pour rnis et osi. Cettte couche a pour but de fournir a ses utilisateurs le service reseau osi (iso8343). Nos connaissances du modele osi ont ete appliquees en particulier a la structuration de protocoles rnis selon des notions osi. Nous avons egalement developpe le module d'administration du terminal. Ces deux projets soulignent bien les besoins de normalisation supplementaire du rnis en ce qui concerne la compatibilite avec l'architecture de reference osi

Full textAbstract:
Denne avhandlingen fokuserer på hvordan informasjon fra mange forskjellige samlinger kan gjøres lettere tilgjengelig for informasjonsbrukere. I dagens informasjonssamfunn finnes og produseres det store mengder digital informasjon, og mange organisasjoner og bedrifter anvender derfor beskrivende metadata til å organisere informasjonen sin i mange ulike samlinger/databaser. Dette fører til at personer som ønsker å søke etter informasjon, må forholde seg til tilsvarende mange forskjellige søkesystemer og søketeknikker. Fra disse brukernes ståsted er det ønskelig med et søkesystem som gjør det mulig å søke etter informasjon fra et stort antall samlinger/databaser på ett sted.
Problemstillingen som ligger til grunn for oppgaven er todelt. For det første skal det undersøkes hvordan man kan utforme en arkitektur som muliggjør samtidig søking i flere heterogene metadatabaser. For det andre skal det undersøkes hvordan denne arkitekturen kan anvendes til å bygge opp et enhetlig søkegrensesnitt som gir brukeren tilgang til ressursbeskrivelser fra alle de heterogene metadatabasene.
Forutsetningen for oppgaven er at arkitekturen skal baseres på metadatahøsting ved hjelp av OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting). Dessuten skal Fast Data Search anvendes som indekserings- og søkesystem.
I denne avhandlingen presenteres et forslag til et system som, basert på metadatahøsting fra flere forskjellige datakilder og påfølgende sentral indeksering av de innhøstede metadataene, tilbyr en enhetlig søketjeneste. Dette gjør det i praksis mulig å søke i innholdet fra mange datakilder gjennom ett felles søkegrensesnitt.
Datagrunnlaget i prototypen utgjøres av om lag 1400 metadatabeskrivelser som blir høstet fra tre av Nasjonalbibliotekets samlinger; Digitalt Radioarkiv, Galleri NOR og Mavis. Metadatahøstingen utføres av en OAI-høster som er en videreutvikling av en fritt tilgjengelig høsterapplikasjon med åpen kildekode. Alle metadataene er beskrevet i formatet MODS (Metadata Object Description Schema), som er et mer uttrykksfullt alternativ til Dublin Core. Etter en enkel normalisering, blir metadataene indeksert i Fast Data Search. Et webbasert søkegrensesnitt, med mulighet for både enkelt og avansert søk, gjør det mulig for brukerne å søke i alle de indekserte metadataene.
Hovedkonklusjonen er at metadatahøsting ved hjelp av OAI-PMH er en velegnet metode for å utvikle en felles søketjeneste for informasjon fra mange datakilder. Metoden fungerer også internt i en organisasjon/bedrift. Det er likevel viktig å være bevisst på at eksterne faktorer, som for eksempel variasjoner metadatakvalitet, kan påvirke kvaliteten på søketjenesten. Når metoden anvendes internt i en organisasjon/bedrift, kan det derfor være nyttig å undersøke datakildenes kvalitet på forhånd. På denne måten kan uegnede datakilder utelukkes på et tidlig tidspunkt.
This thesis focuses on how information from a lot of different collections can be made more easily available for information users. Today’s information society contains large amounts of digital information, and many organizations and enterprises therefore employ descriptive metadata when organizing their information in several different collections/databases. This diversity forces people wanting to search for information to deal with a corresponding number of different search systems and techniques. For these users, a search system which makes it possible to locate information from a large number of collections/databases at single spot is desirable.
The problem to be addressed in this thesis is split. Firstly it has to be examined how to model an architecture which supports simultaneous searching in heterogeneous metadatabases. Secondly it has to be examined how this architecture can be employed to build a uniform search interface which gives the user access to resource descriptions from all the heterogeneous metadatabases.
A premise for the thesis is that the architecture should be based on metadata harvesting by means of the OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting). In addition Fast Data Search should be used as the indexing and searching system.
This thesis presents a system suggestion which offers a uniform search service, based on metadata harvesting from several different data sources and subsequent central indexing of the harvested metadata. In practice this makes it possible to search the content of several data sources using one common search interface.
The data foundation in the prototype is constituted by about 1400 metadata descriptions harvested from three collections at the National Library of Norway: Digitalt radioarkiv (Digital Radio Archive), Galleri NOR (photo gallery) and Mavis (multimedia database). The harvesting process is performed by an OAI harvester which is an adaptation of an open source harvester application. All metadata is described using MODS (Metadata Object Description Schema), which is a more expressive alternative to Dublin Core. After a simple normalization process, the metadata is indexed by Fast Data Search. A web based search interface, enabling both basic and advanced search options, makes it possible for the users to search the indexed metadata.
The main conclusion is that metadata harvesting by means of OAI-PMH is a suitable method for developing a common search service for information from various data sources. The method is also applicable for internal use in an organization or enterprise. However, it is important to be conscious about external factors that may affect the quality of the search service, for instance variations in metadata quality. When the method is used internally in an organization/enterprise, it may be useful to examine the quality of the data sources in advance. By doing this, unsuitable data sources can be excluded early in the development process.

Full textAbstract:
This thesis presents data exploiting one of the important chemico-biological characteristics of the transition metal iron: its ability to exist in two oxidation states. Manipulation of the reactivity of iron by ligands has been reflected by the oxygen utilisation or the amount of ferrozine-detectable Fe2+. Ligand-dependent cell associated iron has been demonstrated by prussian blue staining and ferrozinedetectable iron. Iron/8-hydroxyquinoline enters the cell by diffusion, whereas iron dextran is endocytosed as is evident from extensive vesicular staining. The involvement of iron in the cytotoxicity of H202 has been examined (a) indirectly by introduction of reducing agents which restore the cytotoxicity of H202 at 4°C (an effect which is abolished by desferrioxamine) and (b) directly by extracellularly added iron, which enhances the cytotoxicity if the iron is internalised but protects the cell if the iron remains extracellular. Cytotoxicity has been estimated by plating efficiency and by a modified tritiated thymidine incorporation assay permitting a 24 hour delay before exposure to the label. Direct free radical interaction with a ligand itself is exemplified by the production of the nitroxide free radical in desferrioxamine. This causes extensive damage to yeast alcohol dehydrogenase but can be protected by ascorbate, methionine and iron/EDTA but not iron dextran. The findings lend further support for the suggestion that free radical generation by the Fenton reaction enhances the potential cytotoxic effect of H202 provided the reactions occur at critical sites within the cell.

Full textAbstract:
A central issue in significantly large industrial distributed computer control systems, but one largely ignored by systems designers, is the question of the real-time handling of data. Recently, though, it has become evident that many installed systems are not able to meet the requirements of full plant-wide integration and synchronization. It is becoming clear that future distributed control systems will only be capable of performing the very exacting tasks asked of them if they are supported by an inherently time-conscious communication system, together with an ability to handle data from a variety of different computer-based devices, in a cohesive fashion. A glimmer of hope appeared with the General Motors-inspired MAP initiative. Although a milestone in providing standardized computer interconnection, MAP does not adequately address the all-important issue of real time. When this issue is, however, fully understood, it is found that it invades all aspects of systems design, where a primary requirement is for the totally deterministic handling of data - both in transmitting the data and in processing it. As a consequence, in the development of an industrial communications system, all supporting components must be carefully designed to ensure completely predictable performance. This thesis tackles the design issue in the particular context of communication protocols. The thesis postulates that it is vital to design protocols which are not only logically incorrect, but also have a fully defined temporal behaviour. The question then becomes one of identifying suitable tools for use in the specification, design and verification of protocols - both logically and in the time-domain.

Full textAbstract:
Technology is the answer to most of our human needs but every technology is often
accompanied by other challenges which often lead to the evolvement of another technology.
One of the technologies that have greatly impacted our world is that of energy development
out of which the petro–chemical industry is an important one.
The petro–chemical industry remains the main energy hub for our world today through ranges
of products coming from its ambit but not without its own challenges too. One of which is the
issue of breakdown or shut down which always require maintenance. Shutdown, many a
times, may be planned (annual, quarterly, condition–based, time–based, preventive and so on)
or unplanned (run–to–failure).
In any case, maintenance personnel (mechanical, electrical and instrument) must perform their
duties to fix it. In the process of fixing the equipment several factors affect the effectiveness
of the personnel. To improve maintenance activities, factors affecting its effectiveness should
be addressed. Some of the factors that are already been considered are; Overall Equipment
Effectiveness(OEE), Precision maintenance, Maintainability, Computerized Maintenance
Management System (CMMS), Work Order management, Equipment, Logistics, Process
optimization, Supply chain management, Maintenance strategies, Continuous Improvement
Hours and so on. (Taylor, 2000; Siemens.com, 2010)
Of those factors, many people hardly think of ergonomics as a factor of reckoning with
maintenance activities. Ergonomics is mostly thought of in relation to operators and office
workers.
According to National Institute for Occupational Safety and Health in U.S.A (2009),
ergonomic injuries are the most common cause of workplace illness and injury in the United
States. Back injuries and cumulative trauma disorders (CTDs) such as carpal tunnel
syndrome, tendinitis, bursitis and epicondylitis form the majority of non–fatal occupational
injuries and illnesses, costing employers more than 12 billion dollars per year in lost work
time, workers compensation payments and medical expenses.
Of the cost implication of ergonomics ailment reported above, how much of it is related to
maintenance activities? Is there any relationship between maintenance activities andergonomics? In what direction is the relationship? positive or negative? How much is the
impact in either direction? If it is negative, how can we mitigate it? Finally, what are the
benefits, if any? These are some of the vital questions this dissertation is set to answer in
relation to: physical, somatic, medical, overhead cost, production down–time and personnel
morale.
To achieve the afore–mentioned, several research instruments were employed which include;
case studies, questionnaires, physical observations, interviews, literature reviews, internet
resources, journals and other sources (industry experts and professionals).
Relevant keywords and concepts were thoroughly researched in the literature review which
serves as a base for the dissertation.
Two hundred technical personnel (maintenance) serve as the population sample and
questionnaires were administered to them. Technical personnel with appreciable number of
years of experience occupying managerial positions were also interviewed. The outcomes of
all the interviews, observations and questionnaires were analysed and interpreted accordingly
to verify how ergonomics impact maintenance.
This dissertation based on findings, was able to establish that ergonomics impact the activities
of maintenance personnel culminated in proposing an E4M (Ergonomics for Maintenance)
assessor. The assessor alongside utilization guidelines and a training matrix will help to
effectively mitigate the impact of ergonomics on maintenance activities. There is room for
further development of the tool into a computer based package for real–time assessment and
mitigation.
The assessor and its instruments cannot work alone without the commitment of stake–holders
in the industry. That is why recommendations were included for effective application of the
tool.
The dissertation did not overlook the good works the industry has been doing in the area of
creating awareness about repetitive stress injuries among its workforce but only complement
its efforts in areas they might not look into. That is in a bid to improve the effectiveness of its
workforce which will directly increase productivity, profit and stakeholders confidence. On the other hand, it will reduce their indirect losses through; production down–time, medical
cost and over–head costs.
However, the application of the E4M assessor is not limited to the petro–chemical industry
only but finds its applicability in other industries like; manufacturing, aviation, automobile
and any other field where maintenance activities take place particularly in third world
countries.Thesis (M.Ing. (Development and Management Engineering))--North-West University, Potchefstroom Campus, 2011.

L’obiettivo di questo studio è quello di valutare la stabilità termo-ossidativa degli oli quando sono sottoposti a trattamenti termici blandi (temperatura di 100°C e tempi limitati); lo scopo è quello di simulare delle condizioni più prossime alle cotture o preparazioni casalinghe. Sono stati presi in considerazione alcuni parametri chimici che sono abitualmente considerati per valutare l’ossidazione negli alimenti sottoposti a trattamenti termici più estremi come la frittura, e cioè il numero di perossido, la concentrazione di esanale e il valore di p-anisidina. Inoltre, è stata condotta anche un’analisi, innovativa e rapida, del contenuto in acidi grassi ossidati (OFA).
I risultati hanno mostrato che gli oli testati hanno andamenti diversi sia in base alla loro composizione che in funzione dell’indice analizzato. In generale, la temperatura applicata (100°C) per i tempi trattati non è stata sufficiente ad innescare l’ossidazione di molti oli in maniera importante ed esponenziale come invece spesso si osserva per gli stessi oli sottoposti a forti stress termici. Questo comporta che oli raffinati e soprattutto il girasole BO o il V mostrino valori ossidativi ancora a favore, mentre l’EVO si presenti con le concentrazioni più alte dovuto alla presenza di alcuni composti proossidanti che per diverso processo di lavorazione permangono nel prodotto.
Infine, quello che è interessante osservare è che il valore di p-anisidina varia in funzione del tipo di olio, non tanto in funzione del trattamento termico applicato. I valori di OFA, viceversa, mostrano esiti simili tra i diversi oli quando si considerano gli stessi intervalli di tempo. Quando si considera un trattamento termico più blando, come nel nostro caso a 100°C, la quantificazione degli OFA è un parametro che certamente risente dell’effetto del trattamento termico, e di conseguenza da tenere in considerazione.

L'Organisation maritime consultative intergouvernementale fut créée en 1948 afin de centraliser les questions relatives au transport maritime et répondre à la volonté des grandes puissances de maintenir leur contrôle sur les échanges commerciaux par voie maritime. L'ouverture de nouveaux pavillons lors du mouvement général de décolonisation et la fuite des armateurs vers ceux présentant les avantages économiques les plus attractifs ont brutalement freiné l'action de l'Organisation dévoilant les inconvénients d'un système décisionnel centré sur l'influence des transporteurs. Les catastrophes maritimes qui ont marqué la seconde moitié du XXe siècle ont pourtant permis à l'Organisation d'engager une lente transformation pour le développement de son action normative. Bien qu'elle n'exerce pas ses compétences dans le domaine économique, en devenant l'Organisation maritime internationale (OMI), la dimension politique de ses travaux dans le domaine technique lui a conféré une autorité morale fondée sur son expertise. Régulièrement critiquée, l'OMI reste pourtant l'unique institution à réunir l'ensemble des acteurs du secteur maritime. Son action repose sur sa capacité à orienter la discussion et les négociations afin de parvenir à un consensus. Les limites inévitables d'une démarche compromissoire stimule le perfectionnement de sa technique d'élaboration des normes universelles et entretient un mouvement constant de réformes dont la portée n'est pas toujours à la hauteur des attentes. « Sécurité, sûreté et efficacité de la navigation sur des océans plus propres » sont des objectifs qui l'ont poussée à déterminer des orientations stratégiques et à agir dans un cadre de performanceThe Intergovernmental Maritime Consultative Organization (IMCO) was established in 1948 in order to address at a global scale, issues raised by the maritime transport as well as the concern of the most powerful flag to keep their influence in the field. The registries created by the new States following the decolonization and the escape of the ship-owners towards more economic flag slowed down the action of the Organization, highlighting the disadvantages of a decisional system centered on the influence of the shipowners. Major incidents and marine pollutions of the 20th century allowed the slow transformation of the Organization for the development of its normative action. Even if, the organization does not exercise its competence in the economic concerns, when it became the International Maritime Organization (IMO), the political dimension of its work in technical field conferred gradually to it a moral authority based on its expert testimony and its universal vocation. Although modest, the IMO remains the single institution to join together the whole of the actors of the maritime sector and its intervention is paramount. The adoption of universal standards is founded on its capacity to direct the discussion and the negotiation in order to attain a consensus. The inevitable limits of consensus stimulates the improvement of its technique for the adoption of universal standards and maintains a constant evolution which is not always conform of waitings. "Safety, security and effectiveness of navigation on cleaner oceans" are ambitious objectives which pushed it to determine strategic directions and to act within a framework of performance

The airglow due to emissions of atmospheric species is a typical phenomenon of the high mesosphere and lower thermosphere region and has been used to study the dynamic and chemistry of the upper atmosphere. This work had as objective retrieve the atomic oxygen density [O] profile from atomic oxygen O, molecular oxygen (O ), and hydroxyl (OH) emissions, obtained by multichannel photometer at São João do Cariri - Brazil. The technique uses the Chapman distribution to represent the atomic oxygen profile in the MLT region together with data provided by the MSISE-00 model. The [O] density profiles for the year 2005 were used to reconstruct the OI 5577, O and OH height profiles obtained from ground-based airglow, and the results showed temporal behavior quite similar for the two first species, in which the maximum emission occurring in the early evening until ~ 22 hours, while the OH (6,2) emission rate has intensity peaks at different times during the year. The measurements obtained between 1998 and 2003 were used to study the emission seasonality with maximum volumetric emission rates registered during the equinoxes, in accordance with work already reported. The method showed useful and suitable for reconstruction of atomic oxygen density vertical profiles and, therefore, the OI 5577, O and OH height profiles.
A luminescência atmosférica devido às emissões de espécies atmosféricas é um fenômeno típico da região da alta mesosfera e baixa termosfera e tem sido usada para estudar a dinâmica e a química da alta atmosfera. Este trabalho teve como objetivo reconstruir o perfil da densidade do oxigênio atômico [O] a partir de medidas fotométricas das emissões devidas ao oxigênio atômico O, ao oxigênio molecular (O ), e a hidroxila (OH), obtidas em São João do Cariri PB. Os perfis verticais de [O] foram reconstruídos usando o método de distribuição de Chapman com os dados do modelo MSISE-00. Os perfis verticais da densidade [O] para o ano de 2005 foram usados para reconstruir os perfis verticais das taxas de emissão volumétricas do OI 5577 mesosférico, O b (0,1) e OH (6,2) e os resultados apresentaram comportamento temporal bastante semelhante para as duas primeiras espécies, com os máximos de emissão ocorrendo do início da noite até ~ 22 horas, enquanto que a taxa de emissão devida a OH (6,2) apresenta picos de intensidade em horários variados ao longo do ano. As medidas obtidas entre 1998 e 2003 foram usadas no estudo da sazonalidade das emissões em que as máximas taxas de emissão volumétrica das espécies foram encontradas durante os equinócios, em acordo com trabalhos já reportados. O método demonstrou ser útil e satisfatório para reconstrução dos perfis verticais da densidade do oxigênio atômico e, consequentemente, dos perfis da taxa de emissão das espécies.

Retail industry has transformed in the first decade of this century and new trends continue to disrupt it. Rise of the online channel has pushed the entire retail industry to innovate and think of novel ways to attract and retain customers. With increasing competition, retailers need to differentiate themselves and be relevant to customers. 'Customer is King' is more valid today than ever before. From the customer's point of view, convenience of online retailing is attractive, but physical stores continue to have strong appeal. Access to smartphones and the internet gives customers the flexibility to frequently shift between these channels. This poses a great challenge for retailers on how to provide an omnichannel experience that is personalized but not intrusive. This work explores the need for innovation in the retail industry by researching changing customer behavior and socio-economic trends. Customer's affinity for online channels is not debatable, but this does not mean the end of physical retail. This study examines the importance of physical footprint and the new role of Brick & Mortar in omnichannel settings. It looks into facilitators of transformation of physical retail store from point of sale to point of customer experience. Research indicates that online and offline channels will coexist. Channel integration aims to ensure that online and offline channels do not compete with each other, but complement each other. Further, this study reports the benefits and challenges of channel integration. Finally it proposes an implementation roadmap for the channel integration based on the customer value proposition and dynamic roles of each channel in omnichannel retail.

Previous issue date: 2010-04-09This work focuses on two aspects: the integration of a set of digital libraries, repositories and other data providers through the OAI-PMH protocol (Open Archives Initiative Protocol for Metadata Harvesting) and contextualized documents retrieval in this integrated repository. It is proposed the use of ontologies and content analysis of articles in wiki environments in the context definition. The interest in ontologies is in its use as artifacts of specification domain. An ontology is a data model that represents a set of concepts and their relationships within a domain of knowledge. A wiki is a collaborative environment, containing a collection of items connected by hyperlinks, which can be edited collectively by using a web browser. In this work, the wiki environments are used as an auxiliary repository of knowledge to the extraction of relevant terms. Thus, several concepts and relationships that may not be present in the ontology that specifies the domain of knowledge (since the construction of ontologies is a complex process) can be identified. The result of the developed tool processing is a ranking of documents ordered by a higher degree of importance with respect to the query provided by a user and a particular domain of knowledge, which is specified by an ontology.
Este trabalho aborda duas vertentes: a integração de um conjunto de bibliotecas digitais, repositórios e outros provedores de dados por meio do protocolo OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) e a recuperação contextualizada de documentos neste repositório integrado. Propõe-se a definição dos contextos utilizando ontologias e a análise do conteúdo de artigos de ambientes wiki. O interesse em ontologias está no seu uso como artefatos de especificação de domínios. Uma ontologia é um modelo de dados que representa um conjunto de conceitos e seus relacionamentos, dentro de um domínio de conhecimento. Um wiki é um ambiente colaborativo, que contêm uma coleção de artigos conectados através de hiperlinks, que podem ser editados coletivamente, através da utilização de um navegador web. Neste trabalho, os ambientes wiki são utilizados como um repositório de conhecimento auxiliar, para a extração de termos relevantes. Dessa forma, diversos conceitos e relacionamentos que podem não estar presentes na ontologia que especifica o domínio de conhecimento (uma vez que a construção de ontologias é um processo complexo) podem ser identificados. O resultado do processamento da ferramenta desenvolvida é um ranking de documentos ordenado por maior grau de relevância com relação à consulta fornecida por um usuário e a um determinado domínio de conhecimento, que é especificado por uma ontologia.

Find full textAbstract:
Negli ultimi anni vi è stato un ritorno alla coltura della canapa, dovuto principalmente alla sua vasta gamma di applicazioni e al basso impatto della sua coltivazione sull’ambiente, in linea con i nuovi obiettivi produttivi protesi alla sostenibilità dei sistemi agricoli. Nell'Unione Europea il quadro legale per la commercializzazione dei prodotti oleosi a base di canapa è ancora ambiguo e questo può portare alla commercializzazione di prodotti molto differenti da un punto di vista qualitativo e, dunque, alla individuazione di possibili frodi. L’obiettivo di questo studio è stato valutare la corretta classificazione merceologica di due differenti oli di canapa spremuti a freddo attraverso la determinazione analitica degli stigmastadieni, applicando un metodo semplificato per la determinazione dei medesimi rispetto alla metodica ufficiale esposta nell’allegato XVII del REG. CEE 2568/91. Inoltre, è stato indagato il colore di alcuni campioni al fine di valutare una possibile correlazione tra la classificazione merceologica del prodotto in esame e il suo spettro di trasmissione. Il metodo per la determinazione degli stigmastadieni prevede l’iniezione in modalità splitless dell’olio in gascromatografia (GC) utilizzando un rivelatore a ionizzazione di fiamma. Per misurare il colore degli oli è stato utilizzato uno spettrofotometro UV-visibile, adatto per la registrazione di spettri di riflettanza e/o trasmittanza dei campioni. Questo studio ha permesso la corretta classificazione merceologica degli oli analizzati e ha mostrato la validità del metodo applicato. Sarebbe utile sottoporre il metodo analitico ad un Proficiency Test e predisporre un piano di campionamento che miri ad accertare l’effettiva qualità degli oli di semi di canapa spremuti a freddo e non raffinati presenti in commercio.

Mestrado em GestãoTem-se verificado alguma discussão na literatura sobre o decréscimo da importância do Marketing nas empresas. De acordo com alguns estudos, apenas 10% do tempo é dedicado ao departamento de Marketing nas suas reuniões gerais. O estudo de caso é dedicado a uma empresa portuguesa, Oliveira & Irmão, líder ibérica de produtos de instalação sanitária que atua no mercado há 60 anos. Esta empresa exporta 80% da sua produção e tornou-se reconhecida por ser uma das empresas mais inovadoras da sua àrea, contando atualmente com 40 patentes ativas. Neste estudo será analisada a influência do departamento de Marketing numa empresa com gestão familiar e onde a satisfação do cliente é o seu objetivo primário. Para compreender as alterações que se verificaram desde a implementação do Departamento de Marketing, foram realizadas quatro entrevistas aos diretores da empresa (Departamento Financeiro, Inovação, Comercial e Marketing) para compreender, através do seu ponto de vista, quais as implicações e modificações principais que sentiram. Verificou-se que apesar do departamento de Marketing ser recente na empresa este já realizou algumas alterações notórias a nível interno (comunicação interna) e a nível externo (posicionamento da marca no mercado). Contudo, um dos grandes entraves tem sido a dificuldade em participar no processo desenvolvimento de novos produtos, que até então é coordenado pelo departamento de Inovação e departamento Comercial. A autora do estudo propõe um processo em que o departamento de Marketing fornece os inputs para o desenvolvimento de novos produtos, de modo a satisfazer as necessidades dos clientes.
There have been various discussions in the literature concerning the decreasing significance of marketing in companies. According to some studies, only 10% of time in general meetings is devoted to the marketing department. This case study is dedicated to a Portuguese company, Oliveira & Irmão, Iberian leading supplier of plumbing equipment that has been operating in the market for 60 years. This company exports 80% of its production and has become recognized as one of the most innovative companies in its area, with 40 active patents. This study analyses the influence of the marketing department in a family managed company where client satisfaction is the primary goal. Four interviews with company directors (Finance, Innovation, Sales, and Marketing Departments) were conducted to fully grasp the changes made since the implementation of the marketing department and in order to understand, from their point of view, the implications and major modifications they experienced. This study found that despite the fact that the Marketing department is a recent addition to the company, it has already made some notable changes internally (internal communication) and externally (brand positioning in the market). However, the major hurdle has been the difficulty in participating in the process of developing new products, which to date is coordinated by the Department of Innovation and the Sales department. The author proposes a process in which the Marketing department provides inputs for the development of new products in order to satisfy customer needs.

Full textAbstract:
Il presente lavoro di tesi si propone di verificare se le tecniche elettrochimiche consentano di effettuare una classificazione del cultivar dell’olio.
In particolare si vuole proporre un nuovo metodo per eseguire misure voltammetriche con un microelettrodo di platino direttamente in campioni di olio extravergine di oliva a cui sono aggiunti RTILs (Room Temperature Ionic Liquids) per rendere le matrici adeguatamente conducibili e quindi adatte per le analisi.
I voltammogrammi ciclici dovranno poi essere elaborati attraverso diverse tecniche chemiometriche con l’obiettivo di discriminare i campioni sulla base della loro origine.
Si studieranno quindi delle metodologie analitiche che potrebbero consentire di riconoscere l'origine delle olive usate per produrre un olio e di verificarne l'aderenza alle normative o ai disciplinari delle DOP e l'eventuale presenza di materiale estraneo. Le ricerche hanno l’obiettivo di individuare nell'olio il “fingerprint” da cui sarà possibile risalire alle varie cultivar di provenienza, identificando la composizione e l'origine dell'olio, ciò consentirà inoltre di difendere i consumatori da eventuali frodi commerciali.

Full textAbstract:
Obiettivo della tesi è riconoscere i fattori di successo e i principali
limiti legati all’implementazione dei progetti di recupero degli oli
domestici sul territorio italiano.
Il problema nasce dall’ esigenza di gestire in modo efficiente la raccolta
differenziata di questo rifiuto che, se gettato nello scarico di casa o nel
lavandino, provoca impatti ambientali rilevanti rendendo particolarmente
difficoltoso e dispendioso il trattamento delle acque reflue e causa gravi
danni agli ecosistemi naturali.
La questione è da tempo inquadrata e disciplinata dalle direttive
comunitarie in materia di rifiuti e dalla strategia “Europa2020” che ha
come obiettivo principale una crescita intelligente, sostenibile ed inclusiva.
A livello nazionale, invece, il Testo Unico Ambientale assolve alla
funzione principale di riordino e coordinamento della disciplina, dando
attuazione ai principi comunitari in materia e conformando l’ordinamento
nazionale agli obiettivi e alle priorità individuate dal legislatore europeo.
Gli oli esausti domestici sono un rifiuto scomodo e complesso da gestire
ma la valorizzazione energetica può essere una valida alternativa ai sistemi
di smaltimento classici.
Infatti, attraverso un semplice processo chimico l’olio da cucina usato può
essere trasformato in biodiesel. Questo particolare biocombustibile rispetta
tutti i criteri di sostenibilità imposti dalla Comunità Europea e riduce,
inoltre, l’impatto della produzione di biocarburanti sull’agricoltura.
