Full textAbstract:
In the 1970’s Managed Investment Funds began to source funds directly from the public for investment in the capital markets. The main selling feature of the funds was that they could accumulate a pool of investment capital which would then be invested to earn returns, through economies of scale, in excess of those that could be earned by the investors individually.
Investors in managed funds usually benchmark the performance of their investments, and by default the performance of the fund managers, against the returns available on the index. So that they may at least mimic the return on the index many fund managers will weight the assets in their portfolio to match that of the index.
The present study uses a raw return, a dividend adjusted return and a market model return to analyse the impact on investors returns of shares that either enter or exit Australia’s benchmark market index. The period of the study is between the introduction of the benchmark S&P ASX 200 Index in April 2000 and December 2004.
The present study finds conclusive evidence that the announcement of changes to the index does not contain any information of which the market is unaware. In fact there is strong evidence that investors begin to respond to potential changes in the in index constituents six months prior to the actual change.
These results differ significantly from those found in studies on the US and the UK markets and are of importance to those investors that attempt to track returns of the index.
The results of the present study also provide strong evidence of the dominance of the funds management industry in the Australian market. This has significance for the small investor who is trying to compete and manage their portfolio for themselves.

Muttharam, M. "Engineering Behaviour Of Ash-Modified Soils Of Karnataka." Thesis, Indian Institute of Science, 2000. http://hdl.handle.net/2005/256.
Full textAbstract:
During a survey of black cotton soil zones of Karnataka, indigenously stabilized black cotton soil deposits were encountered in Belgaum, Bijapur, Bagalkot and Gadag Districts of Karnataka. These modified black cotton soils have low swelling and negligible shrinkage tendencies. Owing to their low volume change potential on moisture content changes, these soils are widely preferred in earth construction activities. The exact origin of these modified black cotton soil deposits is not known. According to anecdotal references, these soils were prepared by mixing unknown proportions of wood ash, organic matter and black cotton soil and allowing them to age for unknown periods of time. As wood-ash was apparently used in their preparation, these modified black cotton soils are referred to as ash-modified soils (AMS) in the thesis.
The practice of preparing ash-modified soils is no longer pursued in black cotton soil regions of Karnataka and the available supply of this indigenously stabilized soil is being fast depleted. Also, attempts have not been made to characterize the physico-chemical and engineering properties of AMS deposits of Karnataka. Given the widespread utilization of ash-modified soils in black cotton soil areas of Karnataka, there is a need to understand their physico-chemical and engineering behaviour and the physico-chemical mechanisms responsible for their chemical modification.
Swelling and shrinkage of expansive soil deposits are cyclic in nature due to periodic climatic changes. Chemically stabilized black cotton soil deposits are also expected to experience cyclic wetting and drying due to seasonal climatic changes. The impact of cyclic wetting and drying on the swelling behaviour of natural expansive soils is well-documented. However, the impact of alternate wetting and drying on the swelling behaviour of admixture stabilized expansive soils (these include natural - ash-modified soils and laboratory - lime stabilized black cotton soils) has not been examined. Such a study would be helpful to assess the long term behaviour of admixture stabilized soils in field situations.
To achieve the above objectives, experiments are performed that study:
1.The physico-chemical and engineering properties of ash-modified soils from different Districts of Karnataka. The physico-chemical and engineering properties of natural black cotton soil (BCS) specimens from locations adjacent to ash-modified soil deposits are also examined to understand and evaluate the changes in the engineering characteristics of the ash-modified soils due to addition of admixtures.
2. Identify the physico-chemical mechanisms responsible for the chemical stabilizationof ash-modified soils.
3.The influence of cyclic wetting and drying on the wetting induced volume changebehaviour of admixture stabilized black cotton soils, namely, ash-modified blackcotton soils and lime stabilized black cotton soils.

Yang, Fan. "High Grade Magnetic Material Extraction from Coal Fly Ash." OpenSIUC, 2010. https://opensiuc.lib.siu.edu/theses/201.
Full textAbstract:
Since a substantial amount of coal combustion byproducts (CCB) are produced each year, generating value-added product from fly ash, which is a major constituent of these CCBs, has been an important area of research for several decades. Natural magnetite (NM), which is used to maintain dense medium slurry pulp density in coal preparation plants, has a current market value of more than $200 per ton. The use of fly ash derived magnetite (FAM) as an alternative to natural magnetite has potential benefits for dense medium processes, such as lower cost, greater stability at low medium density, more efficient delivery systems. This study developed a suitable processing scheme to extract high-grade (> 96%) magnetite from fly ash generated from burning high sulfur coal, and investigated the suitability of the FAM product for dense medium application in coal preparation plants. A classifying cyclone was utilized in the process flow sheet for the pre-concentration of FAM in its underflow stream, which was enriched to high grade FAM by a single stage wet magnetic separator of low intensity (~1000 gauss). A statistically designed experimental program was utilized to maximize the magnetite grade and recovery achieved from the above mentioned flow sheet. The FAM product particles had a slightly coarser particle size distribution than the NM particles. In addition, the FAM particles were found to have a spherical shape; but about one unit lower specific gravity in comparison to the NM particles. However, the F5 Stability Index of the resulting FAM product was found to be in the desired range of 30 to 40 for its suitable application as a dense medium. The coal cleaning performance obtained from a 0.15 m diameter dense medium cyclone using dense medium prepared from both of FAM and NM, were quite similar. However, the effective separation density (SG50) obtained from the FAM-based dense medium was significantly different from the medium density; this may need further investigation in future. A preliminary economic analysis, conducted for a hypothetical mini-plant having a fly ash handling capacity of 100 ton/hour, indicated the cost of FAM extraction to be nearly $5/ton. The cost assumes that the FAM extraction plant is located at the fly ash producing utility site and does not include the cost of thermal drying that may be required to reduce the moisture content of the FAM filter cake produced at the FAM plant. A preliminary civil engineering study conducted to investigate the effect of FAM extraction on the compressive strength property of the non-magnetic flyash (left behind after FAM extraction) failed to produce a conclusive finding. The specimens prepared using 10% and 30% fly ash replacements indicated that the compressive strength does not change due to FAM extraction. However, the specimens using 20% fly ash replacement indicated that compressive strength does change due to FAM extraction. Hence, a more detailed study is recommended to investigate this discrepancy.

This thesis, whose title is DEVELOPMENT AND SOCIAL ASSISTANCE: AN EFFECTIVENESS EVALUATION IN SOCIAL ASSISTENCE POLICY IN THE CITIES OF ASS? AND MOSSOR?/RN (2004/2008), has as main aim to evaluate effectiveness in Social Assistance Policy in the cities of Assu and Mossor?/RN, from 2004 to 2008, identifying its impacts and effects in life of its users. The methodological process for the research was composed by: a) Literature review on this theme, development of public policies; social public policies, public policy evaluation and Social Assistance Policy in Brazil; b) Documental research from Municipal Management of Social Development and Municipal Counsels of Social Assistance in the cities of Assu and Mossor?/RN about the object of this study and empirical field; c) Field Research constituted by the realization of Focal Groups with Social Assistance users and semistructured interviews with municipal managers from Ass? and Mossor?. It was also taken into account participant observations in events and activities related to Social Assistance previously mentioned, considering field management and also the response to users demands. Articulating the themes of Development and Public Social Policy in Social Assistance was the theoretical purpose for this thesis. To achieve this purpose, it was performed two theoretical displacements related, at the same time, to the notion of development and to the concept of Social Assistance, which means to comprehend development as social change and improvement in users life quality, expressed in the expansion of their capacities and liberties (SEN, 1993, 2000), and the Social Assistance as an element for development. Such displacements provide a view of Public policy and Social Policies and evaluate National Policy of Social Assistance achieved in those cities. As product, this thesis presents a methodological purpose for effectiveness evaluation in Public Policy, taking into account expansion of capacities and liberties, concluding that Social Assistance Policy in Ass? and Mossor?/RN, even in lesser extent had its impact and caused effective results in the life of their users and provided an expansion of their capacities and liberties, improving life quality and empowered agent condition for those subjects. The results show that this Policy has been proved to be effective, and consequently, it was considered, in this thesis, to be also an element and an allied for development

Full textAbstract:
Hybrid aspen is a crossbreed between European and North American aspen. It is a fast growing tree species that has shown strong growth in the South of Sweden. The follow-ups that have been made on hybrid aspen stands, have mainly been done on plant material in the South of Sweden. In the North of Sweden, only occasional studies have been made, and the knowledge of Northern hybrid aspen stands is, thus, unsatisfactory. In the South of Norrland, land owners have planted hybrid aspen, but what kind of plants it is, and how well these stands have established, is not ascertained, since data has not been compiled on the subject. The objective of this study is to evaluate practical plantations of hybrid aspen in the South of Norrland regarding height growth, survival and damages. The ambition is to increase the knowledge about practical plantations regarding height growth, survival and damages, and from the conclusions thereof, give recommendations for future establishments of hybrid aspen in the area. For the study, eight hybrid aspen stands in the South of Norrland were localised. Inventories were made of the stands, the land owners were interviewed and the material was compiled and analysed. Annual height growth varied amongst the stands between 0,4 and 1 meter and was in average 0,6 meter. Survival varied between 41 and 100 percent, with a mean value of 70 percent. The proportion of damaged stems varied between 0 and 85 percent, with a mean value of the stands of 27 percent. Plant mortality was explained by the land owners to be a result of field-mouse damages, which is confirmed by earlier research. The examined hybrid aspen stands in the South of Norrland demonstrate varying results in terms of height growth, survival and damages, but mainly a result that makes the tree species interesting as an alternative to traditional tree species.Hybridasp är en korsning mellan europeisk och nordamerikansk asp. Det är ett snabbväxande trädslag som har påvisat god tillväxt i södra Sverige. De uppföljningar som har gjorts på hybridaspbestånd har främst varit på plantmaterial i södra Sverige. I norra Sverige har det endast gjorts enstaka undersökningar och kunskapen om de nordliga hybridaspbestånden är därför bristfällig. I södra Norrland har markägare planterat hybridasp, men vilket plantmaterial det är och hur dessa bestånd har etablerat sig, är i dagsläget osäkert då det inte finns någon sammanställd data över detta Undersökningens syfte är att utvärdera praktiska planteringar av hybridasp i södra Norrland avseende höjdtillväxt, överlevnad och skador. Målet är att öka kunskapen om praktiska planteringar avseende höjdtillväxt, överlevnad och skador och utifrån slutsatser av detta ge rekommendationer för framtida etableringar av hybridasp i området. För studien lokaliserades åtta hybridaspbestånd i södra Norrland. Bestånden inventerades, markägarna intervjuades och materialet sammanställdes och analyserades. Höjdtillväxten per år varierade i bestånden mellan 0,4 och 1,1 meter och var i medeltal 0,6 meter. Överlevnaden varierade mellan 41 och 100 procent med ett medelvärde på 70. Andel skadade stammar varierade mellan 0 och 85 procent med ett medelvärde för bestånden på 27 procent. Avgångarna förklaras av markägarna till största del beror på sorkskador, vilket tidigare forskning styrker. Undersökta hybridaspbestånd i södra Norrland påvisar varierande resultat vad gäller höjdtillväxt, överlevnad och skador men överlag ett resultat som gör trädslaget intressant som alternativ till de traditionella trädslagen.

Full textAbstract:
We introduce a simple approach extending the input language of Answer Set Programming (ASP) systems by multi-valued propositions. Our approach is implemented as a (prototypical) preprocessor translating logic programs with multi-valued propositions into logic programs with Boolean propositions only. Our translation is modular and heavily benefits from the expressive input language of ASP. The resulting approach, along with its implementation, allows for solving interesting constraint satisfaction problems in ASP, showing a good performance.

Für den Flugverkehr als Teil eines regional und global verdichteten Infrastruktursystems sind Naturgefahren wie Vulkanausbrüche gleichbedeutend mit Risiken. Die Kommunikation von Risiken verläuft im Spannungsfeld von wirtschaftlichen und staatlichen Akteuren einerseits und Medien und Zivilgesellschaft andererseits. Demgegenüber stehen Modelle diskursiver Risikoregulierung als Instrumente öffentlicher Aushandlungsprozesse. Diskutiert werden Einflussfaktoren auf Entscheidungen im Kontext von Risikodiskursen. Dabei wird insbesondere die Funktionslogik der Medien untersucht. Am Beispiel der Aschewolke des Eyjafjallajökull 2010 wird die Phänomenkonstellation von Akteuren und Diskurspositionen illustriert und der Verlauf einer medialen Risikoentwicklung nachgezeichnet.

Full textAbstract:
A lack of knowledge about individuals with autism spectrum disorder (ASD) can create stereotypes, which serve as barriers to interaction. Television is a component in the development of social attitudes in teenagers. Using social learning theory as a framework, the purpose of this quantitative 2-group, posttest only, experimental design was to determine whether observational learning could be effective in generating positive teen attitudes toward peers with ASD. Senior high school students (N = 130) completed the Attitude Toward Disabled Persons (ATDP) Survey to determine whether observing a video clip can positively affect the attitudes of teens about their peers with ASD. A t test for independent sample groups was used to compare mean scores on the ATDP. According to study findings, 18-year-old students who watched a video clip of a panel of teens with ASD had more positive attitude scores (M = 74.91, SD = 8.4) than did the 18-year-old students who watched an innocuous video clip (M = 48.57, SD = 9.1), t (128) = 17.14, p < .0001. This finding was in alignment with the research on the impact of media on teen attitudes. The media representation of persons with disabilities may facilitate social change by helping to reduce negative stereotypes and to promote positive attitudes about person with specific disabilities. Positive attitudes toward teens with ASD can lead to positive social interactions between teens with and without ASD. In addition, this research may produce social change by fostering social experiences and opportunities for teens with ASD to learn social behaviors and social language by modeling their typical peers.

Blume, Theresa. "Hydrological processes in volcanic ash soils : measuring, modelling and understanding runoff generation in an undisturbed catchment." Phd thesis, Universität Potsdam, 2008. http://opus.kobv.de/ubp/volltexte/2008/1655/.
Full textAbstract:
Streamflow dynamics in mountainous environments are controlled by runoff generation processes in the basin upstream. Runoff generation processes are thus a major control of the terrestrial part of the water cycle, influencing both, water quality and water quantity as well as their dynamics. The understanding of these processes becomes especially important for the prediction of floods, erosion, and dangerous mass movements, in particular as hydrological systems often show threshold behavior. In case of extensive environmental changes, be it in climate or in landuse, the understanding of runoff generation processes will allow us to better anticipate the consequences and can thus lead to a more responsible management of resources as well as risks.
In this study the runoff generation processes in a small undisturbed catchment in the Chilean Andes were investigated. The research area is characterized by steep hillslopes, volcanic ash soils, undisturbed old growth forest and high rainfall amounts.
The investigation of runoff generation processes in this data scarce area is of special interest as a) little is known on the hydrological functioning of the young volcanic ash soils, which are characterized by extremely high porosities and hydraulic conductivities, b) no process studies have been carried out in this area at either slope or catchment scale, and c) understanding the hydrological processes in undisturbed catchments will provide a basis to improve our understanding of disturbed systems, the shift in processes that followed the disturbance and maybe also future process evolution necessary for the achievement of a new steady state. The here studied catchment has thus the potential to serve as a reference catchment for future investigations.
As no long term data of rainfall and runoff exists, it was necessary to replace long time series of data with a multitude of experimental methods, using the so called "multi-method approach". These methods cover as many aspects of runoff generation as possible and include not only the measurement of time series such as discharge, rainfall, soil water dynamics and groundwater dynamics, but also various short term measurements and experiments such as determination of throughfall amounts and variability, water chemistry, soil physical parameters, soil mineralogy, geo-electrical soundings and tracer techniques. Assembling the results like pieces of a puzzle produces a maybe not complete but nevertheless useful picture of the dynamic ensemble of runoff generation processes in this catchment. The employed methods were then evaluated for their usefulness vs. expenditures (labour and financial costs). Finally, the hypotheses - the perceptual model of runoff generation generated from the experimental findings - were tested with the physically based model Catflow. Additionally the process-based model Wasim-ETH was used to investigate the influence of landuse on runoff generation at the catchment scale.
An initial assessment of hydrologic response of the catchment was achieved with a linear statistical model for the prediction of event runoff coefficients. The parameters identified as best predictors give a first indication of important processes. Various results acquired with the "multi-method approach" show that response to rainfall is generally fast. Preferential vertical flow is of major importance and is reinforced by hydrophobicity during the summer months. Rapid lateral water transport is necessary to produce the fast response signal, however, while lateral subsurface flow was observed at several soil moisture profiles, the location and type of structures causing fast lateral flow on the hillslope scale is still not clear and needs to be investigated in more detail. Surface runoff has not been observed and is unlikely due to the high hydraulic conductivities of the volcanic ash soils. Additionally, a large subsurface storage retains most of the incident rainfall amount during events (>90%, often even >95%) and produces streamflow even after several weeks of drought. Several findings suggest a shift in processes from summer to winter causing changes in flow patterns, changes in response of stream chemistry to rainfall events and also in groundwater-surface water interactions. The results of the modelling study confirm the importance of rapid and preferential flow processes. However, due to the limited knowledge on subsurface structures the model still does not fully capture runoff response. Investigating the importance of landuse on runoff generation showed that while peak runoff generally increased with deforested area, the location of these areas also had an effect.
Overall, the "multi-method approach" of replacing long time series with a multitude of experimental methods was successful in the identification of dominant hydrological processes and thus proved its applicability for data scarce catchments under the constraint of limited resources.Die Abflussdynamik in Mittel- und Hochgebirgen wird durch die Abflussbildungsprozesse im Einzugsgebiet bestimmt. Diese Prozesse kontrollieren damit zu großen Teilen den terrestrischen Teil des Wasserkreislaufs und beeinflussen sowohl Wasserqualität als auch -quantität. Das Verständnis von Abflussbildungsprozessen ist besonders wichtig für die Vorhersage von Hochwasser, Erosion und Massenbewegungen (z.B. Erdrutsche) da hydrologische Systeme oft Schwellenwertverhalten aufweisen. Im Falle weit reichender Umweltveränderungen, wie z.B. Klima- oder Landnutzungsänderungen kann das Verständnis der Abflussbildungsprozesse ein verantwortungsvolleres Management sowohl der Ressourcen als auch der Risiken ermöglichen. In dieser Studie wurden die Abflussbildungsprozesse in einem kleinen, anthropogen unbeeinflussten Einzugsgebiet in den Chilenischen Anden untersucht. Das Untersuchungsgebiet ist durch steile Hänge, vulkanische Ascheböden, ungestörten Naturwald und hohe Niederschlagsmengen charakterisiert. Die Erforschung von Abflussbildungsprozessen ist hier von besonderem Interesse, da a) wenig über das hydrologische Verhalten der hochporösen und hochleitfähigen jungen Ascheböden bekannt ist, b) in dieser Region bisher keine Studien auf Hang- oder Einzugsgebietsskala durchgeführt wurden, und c) das Prozessverständnis in ungestörten Einzugsgebieten als Basis zum besseren Verständnis bereits anthropogen beeinflusster Gebiete dienen kann. Das hier untersuchte Gebiet hat daher das Potential zum Referenzgebiet für zukünftige Studien und Forschungsprojekte. Bedingt durch die Kürze der vorliegenden Abfluss- und Niederschlagszeitreihen war es nötig, den bestehenden Datenmangel durch eine Vielzahl von experimentellen Methoden und Ansätzen auszugleichen. Dieser Ansatz wird im Folgenden der "Multi-Methoden-Ansatz" genannt. Die ausgewählten Methoden sollten dabei so viele Aspekte der Abflussbildung abdecken wie möglich. Es wurden daher nicht nur Zeitreihen von Abfluss, Niederschlag, Bodenfeuchte- und Grundwasserdynamik gemessen, sondern auch eine große Zahl an Kurzzeitmessungen und Experimenten durchgeführt. Diese beinhalteten u.a. Messung des Bestandesniederschlags, Bestimmung der Wasserchemie, Bestimmung bodenphysikalischer Parameter und der Bodenmineralogie, sowie geophysikalische Messungen und Tracermethoden. Die Synthese der Resultate gleicht dem Zusammensetzen eines Puzzles. Das so entstandene Bild des dynamischen Prozess-Ensembles ist trotz möglicher fehlender Puzzlestücke hochinformativ. In einem nächsten Schritt wurden die ausgewählten Methoden im Hinblick auf Erkenntnisgewinn und Kosten (d.h. finanzielle Kosten und Arbeitszeit) evaluiert. Das durch die experimentellen Ergebnisse gewonnene Bild der Abflussbildung wurde anschließend mit Hilfe des physikalisch basierten Modells Catflow überprüft. Weiterhin wurde mit dem prozessbasierten Modell Wasim-ETH der Einfluss der Landnutzung auf die Abflussbildung auf Einzugsgebietsskala untersucht. Die Ergebnisse des "Multi-Methoden-Ansatzes" zeigen, dass die Abflussreaktion in diesem Gebiet sehr schnell erfolgt. Vertikales präferenzielles Fliessen ist hier von großer Bedeutung und wird in den Sommermonaten noch durch Hydrophobizitätseffekte verstärkt. Schneller lateraler Fluss im Untergrund ist eine weitere Vorraussetzung für die schnelle Reaktion des Abflusses (Oberflächenabfluss ist hier aufgrund der hohen hydraulischen Leitfähigkeiten unwahrscheinlich). Obwohl bei der Untersuchung der Bodenfeuchtedynamik in einigen Profilen laterale Fließmuster beobachtet wurden, ist die Art und Lage der Untergrundstrukturen, die auf der Hangskala schnellen lateralen Fluss verursachen, noch unklar und sollte genauer untersucht werden. Die Tatsache, dass bei Niederschlagsereignissen der Großteil der Niederschlagsmenge nicht zum Abfluss kommt (>90%, oft auch >95%), sowie der kontinuierliche Abfluss selbst nach Wochen der Trockenheit, lassen auf einen großen unterirdischen Speicher schließen. Der Wechsel von Winter (nass) zu Sommer (trocken) scheint Veränderungen im Prozess-Ensemble hervorzurufen, die sich in der Änderung von Fließmustern, von Grundwasser-Oberflächenwasser-Interaktionen, sowie veränderter Reaktion der Wasserchemie auf Niederschlagsereignisse beobachten ließ. Die Modellstudie bestätigte die Bedeutung der schnellen Fließwege. Als Folge von Informationsdefiziten über die Strukturen des Untergrunds ließ sich jedoch die Abflussbildung noch nicht vollständig reproduzieren. Die Untersuchung zur Bedeutung der Landnutzung für die Abflussbildung mit Hilfe eines Einzugsgebietsmodells zeigte die Zunahme der maximalen Abflüsse mit zunehmender Entwaldung. Weiterhin erwies sich auch die Lage der abgeholzten Flächen als ein wichtiger Faktor für die Abflussreaktion. Der "Multi-Methoden-Ansatz" lieferte wichtige Erkenntnisse zum Verständnis der Abflussbildungspozesse in den Anden Südchiles und zeigte sich als adäquates Mittel für hydrologische Prozess-Studien in datenarmen Gebieten.

No Brasil, a questão dos Resíduos de Serviços de Saúde (RSS) tem sido uma questão muito discutida nas últimas décadas, conforme preconiza a legislação atual ditada pela ANVISA, RDC 306/2004 e CONAMA 358/2005, que visam conjuntamente melhorias no campo da saúde pública e a proteção do meio ambiente. Percebe-se, porém, que na prática a legislação se apresenta como uma questão formal ou científica ainda longe de sua aplicabilidade em vários serviços de saúde. Dentro desta realidade, esse trabalho objetivou analisar a dinâmica do gerenciamento dos resíduos sólidos no Hospital Regional da Asa Norte, no ano de 2008. Assim realizou-se um estudo transversal descritivo com dados provenientes do levantamento do quantitativo de resíduos sólidos gerados nas diferentes unidades do referido hospital caracterizando as fontes produtoras e o grupo de resíduo gerado. Concomitantemente foi feita uma avaliação do manejo deste resíduo abarcando as etapas de: segregação, acondicionamento, identificação, transporte interno, armazenamento temporário, tratamento e armazenamento externo, de acordo com os ditames da legislação atual. Dentro do manejo do RSS também foram abordados aspectos da saúde ocupacional dos profissionais enfermeiros, técnicos de enfermagem e auxiliares de higienização. Foram aplicados formulários com entrevistas semi-estruturadas envolvendo diferentes variáveis em relação ao perfil profissional, acidentes ocupacionais, manejo do resíduo e percepção destes profissionais em relação aos RSS. Os dados foram avaliados utilizando o sistema SPSS versão 17.0. Os resultados indicam que o quantitativo de resíduo gerado por dia foi de 1.706,04 Kg/dia representando 51,182 Kg/mês. A taxa média de resíduos produzido por leito foi de 4,266 Kg/leito/dia. A unidade de terapia Intensiva apresentou-se como a maior geradora de resíduo por paciente 5,76kg/paciente/dia. Em relação ao manejo do resíduo foram encontradas falhas em todas as etapas desde a segregação até o acondicionamento externo. Foram entrevistados 71 enfermeiros, 133 Técnicos de enfermagem e 140 Auxiliares de Serviços Gerais. Nas três classes de profissionais entrevistados, enfermeiros, técnicos de enfermagem e auxiliares de serviços gerais, a maioria foi de mulheres, representando: 58 (81,7%), 99 (74,4%) e 127 (90,7%) respectivamente. A faixa etária dos enfermeiros foi de 22 (31,0%) entre 31 a 40 anos, seguidos de 41 a 50 anos. A faixa etária mais freqüente dos técnicos de enfermagem e auxiliares de serviços gerais foi de 49 (36,8%) entre 41 a 50 anos, e 49 (35,0%) entre 31 a 40 anos respectivamente. Nas três classes de profissionais se verificou que a grande maioria era de fora do Distrito Federal, ou seja, procedente de outros Estados, sendo 37 (52,1%) dos enfermeiros, 75 (56,4%) dos técnicos de enfermagem, e 98 (70%) dos auxiliares de serviços gerais. O tempo de profissão para os enfermeiros variou entre 8 a 11 anos e 20 a 29 anos representando em ambos os casos 15 (21,1%), para os técnicos de enfermagem o tempo foi de 20 a 29 anos e 4 a 7 anos representando 33 (24,86%) e 30 (22,6%) e para os auxiliares de serviços gerais 61 (43,5%), o tempo foi menor que 7 anos. Quanto à situação vacinal dos enfermeiros, 65 (91,5%) informaram possuir cartão de vacinas, porém somente 32 (45,1%) possuíam cartão completo. Para os técnicos de enfermagem, 121 (91,0%) possuíam cartão de vacinas e 33 (24,8%) informaram ter cartão completo. Os auxiliares de serviços gerais, 112 (80,0%) informaram ter cartão de vacinas e somente 10 (7,1%) informaram possuir cartão completo. Em relação à capacitação para o manejo do RSS, só o grupo de auxiliares de serviços gerais foi capacitado 125 (89,3%), observa-se ainda que estes profissionais 77 (55%) receberam entre uma e duas capacitações. O percentual de enfermeiros e técnicos de enfermagem, que foram treinados, corresponde respectivamente a 16 (22,5%) e (26) 19,5 %. Dentre os profissionais que sofreram acidentes de trabalho, os acidentes por perfurocortantes corresponderam a 52 (96,3%) para os técnicos de enfermagem, 21 (84%) para os enfermeiros e 22 (78,6%) para os auxiliares de serviços gerais. Quanto à notificação de acidentes ocupacionais, 23 (82,1%) corresponderam aos auxiliares de serviços gerais, 16 (66,7%) para os enfermeiros e 33 (60%) para os técnicos de enfermagem. O tratamento pós-acidente perfurocortante foi de 37 (38,9%) com quimioprofilaxia com antiretroviral. Em relação à percepção do conhecimento sobre as diferentes fases do manejo de RSS, as três categorias de profissionais não tinham conhecimento ou relataram informações fracionadas. Conclusão, o quantitativo de resíduo gerado se encontra dentro dos limites preconizados pela literatura, mas, existe inadequação do manejo do RSS por falta de conhecimento o que influencia diretamente em aspectos da saúde ocupacional dos trabalhadores, havendo necessidade urgente de implantação de um Plano de Gerenciamento de Resíduos de Serviços de Saúde (PGRSS) e capacitação contínua. ________________________________________________________________________________________ ABSTRACT
In Brazil the question of Medical Waste has been discussed in recent decades under the legislation the ANVISA, RDC 306/2004 and CONAMA 358/2005, than rectify the improvements in the field of public health and environmental protection. But realized that in practice the legislation is presented as a formal or scientific issue still far from its applicability in various health services. This study aimed to analyze the dynamics of management of solid waste in Hospital Regional of Asa Norte in the year 2008. Was performed a descriptive cross-sectional study with information of the amount of solid waste with data from a quantitative collection of solid waste from the various units of the hospital characterizing the sources of production and the group of waste generated. Was evaluated the management of residue with the following stages of: segregation, packaging, identification, internal transport, storage, treatment, and external storage, according to current legislation. In the management of the RSS were also evaluated aspects of the occupational health professional nurses, nursing technicians and worker cleaning. Forms were applied with semi-structured interviews involving different variables on the professional, occupational accidents, management of waste and perception of professionals in relation of medical waste. The information were analyzed using SPSS version 17.0. The results indicate that the amount of waste generated per day was 1.706,04 kg / day representing 51,182 kg / month. The average rate of waste generated per bed was 4.266 kg / bed / day. The intensive care unit was the largest generator unit per patient 5.76 kg / patient / day. For the management of waste were failures at all stages from segregation to the outer packaging. Were interviewed 71 nurses, 133 technicians and 140 nursing auxiliaries of General Services. The three classes of professional interviewers, nurses, technicians nursing and worker cleaning , the majority were women, representing: 58 (81.7%), 99 (74.4%) and 127 (90.7%) respectively . The age of nurses was 22 (31.0%) between 31 to 40 years, followed 41 to 50 years. The most frequent age group of technicians, nursing and worker cleaning was 49 (36.8%) between 41 to 50 years, and 49 (35.0%) between 31 to 40 years respectively. The three classes of professionals were coming from other states outside the Distrito Federal., and 37 (52.1%) of nurses, 75 (56.4%) of the technical, nursing, and 98 (70%) of the worker cleaning. The time of jobs for nurses, ranging from 8 to 11 years and 20 to 29 years in both cases representing 15 (21.1%) for the technicians of nursing time was 20 to 29 years and 4 to 7 years representing 33 (24.86%) and 30 (22.6%) and for worker cleaning 61 (43.5%), the time was less than 7 years. As the vaccination status of nurses, 65 (91.5%) reported having card vaccines, but only 32 (45.1%) had complete card. For the technical, nursing, 121 (91.0%) had vaccination card and 33 (24.8%) reported having full card. The worker cleaning, 112 (80.0%) reported having card vaccines and only 10 (7.1%) reported having full card. In relation to training only to assist the group was capable of general services 125 (89.3%), but 77 (55%) received between one and two training. The percentage of nurses and nursing technicians, who were trained, corresponds respectively to 16 (22.5%) and (26) 19.5%. Among those who have suffered accidents caused by perforating and cutting materials corresponded the 52 (96.3%) for technical nursing, 21 (84%) for nurses and 22 (78.6%) for Worker Claning. As the notification of occupational accidents, 23 (82.1%) corresponded to worker cleaning, 16 (66.7%) for nurses and 33 (60%) for technical nursing. The post-accident treatment was cutting drilled 37 (38.9%) with antiretroviral chemoprophylaxis. Regarding the perception of knowledge about the different stages of the handling of RSS, the three categories of professionals had no knowledge or information reported fractionated. Finding the amount of waste generated is in the literature, there is inadequate management of the RSS by lack of knowledge which directly influences on aspects of occupational health of workers, with the urgent need to implement a continuous training and PGRSS.

Full textAbstract:
La répartition des sucres requiert l'activité de transporteurs membranaires et représente une étape cruciale dans la réponse de la plante au déficit hydrique. Les séquences de 63 transporteurs de sucres ont été identifiées chez la Vigne. L'analyse in silico a identifié 7 sous familles de tranporteurs de monosaccharides et plusieurs élements cis de régulation dans les promoteurs. L'analyse d'expression par macroarray a permis d'identifier 4 gènes de transporteurs fortement exprimés dans tous les organes végétatifs (VvHT1, VvHT3, VvPMT5, VvSUC27), d'autres préférentiellement exprimés dans les feuilles matures (VvHT5), les racines (VvHT2) et les pépins (VvHT3, VvHT5) et 3 régulés au cours du développement de la baie (VvHT2, VvTMT1, VvTMT2). L'analyse par macroarray révèle que l'expression de VvHT5, VvSUC11, VvGIN2 et VvMSA est induite dans les feuilles matures, en réponse au déficit hydrique alors que l'expression de VvHT1 est inhibée. La carence en eau déclenche l'accumulation de glucose, fructose et saccharose dans les feuilles matures de Vigne. Le gène VvMSA a été surexprimé ou réprimé dans des cellules embryogènes de Vigne génétiquement modifiées. La répression de VvMSA diminue l'activité d'absorption du glucose et l'expression de VvHT1. Le phénotype des vitroplants régénérés ainsi que l'expression de VvHT1 et VvMSA ont été étudiés en condition in vitro et ex vitro. Les résultats obtenus suggèrent la présence d'une voie de régulation de l'expression du gène VvHT5 par le fructose. Un modèle de la signalisation glucidique dans l'expression du gène VvHT1 est proposé, comprenant une voie de régulation par les disaccharides et deux par le glucose, un VvMSA-dépendant et un VvMSA-indépendantSugar allocation mediated by membrane transporters is strongly affected by water deficit. The sequences of 63 sugar transporters were identified in Grapevine. The in silico analysis identify 7 monosaccharide transporters subfamilies and several cis elements in the promoter regions. Macroarray expression analysis showed that 4 sugar transporter genes are strongly expressed in all vegetative organs (VvHT1, VvHT3, VvPMT5, VvSUC27), some others are preferentially expressed in mature leaf (VvHT5), in root (VvHT2), in seed (VvHT3, VvHT5) and 3 genes are regulated during berry development (VvHT2, VvTMT1, VvTMT2). Macroarray gene expression analysis showed that VvHT5, VvSUC11, VvGIN2 and VvMSA are up-regulated in mature leaves under drought conditions and that VvHT1 was down-regulated. Water deficit triggers a strong accumulation of glucose, fructose and sucrose in water stressed leaves. VvMSA gene was overexpressed or silenced in grape embryogenic cells by genetic transformation. The silencing of VvMSA affects glucose uptake activity and VvHT1 expession. The Grapevine plants phenotype and the expression of VvHT1 and VvMSA expression were studied under both in vitro and ex-vitro conditions. For the first time, the involvement of sugar transporters and VvMSA in the response to water stress in Grapevine is demonstrated. A model for sugar signalling involved in VvHT1 gene expression is proposed, including a disaccharide pathway and two glucose regulatory mechanisms, one VvMSA-dependent and another VvMSA-independent. Finally, our results reveal the importance of VvHT1 hexoses transporter under heterotrophic conditions

Full textAbstract:
The Montserrat Oriole, Icterus oberi Lawrence, endemic to the West Indian island of Montserrat, has grown critically endangered since volcanic eruption began on that island in 1995. The Soufriere Hills Volcano has devastated much of the oriole's native habitat, and populations within intact forests have plummeted in recent years. One hypothesized cause for the Montserrat Oriole's decline is that low insect prey numbers during the nesting season, as a result of volcanic ash in the environment, is resulting in increased nest failure. The hypothesis of a negative effect of ash on canopy arthropods was tested. Four sites, varying in the level of ash deposition they typically receive, were sampled via canopy fogging over a 14-month period. Results indicate that ash is having a significant negative impact on canopy arthropods, particularly at the sampling sites closest to the volcano, but that that the decline is limited to a few insect taxa. To investigate whether the arthropod taxa utilized by the Montserrat Oriole were among those negatively affected by volcanic ash, observational studies were conducted to identify the main insect prey types and sizes brought to oriole nests, and to examine whether nestling feeding rates have declined since the onset of volcanic eruption. Ortoptera, which were not significantly affected by volcanic ash, were the most important nestling food resources utilized in 2002 and 2003. The most frequently delivered size of prey item was calculated at bill length long (approx. 2 cm), and were not significantly affected by ash. Orioles appear to be selecting their prey from the portion of the insect fauna that is least affected by ash in the environment. Oriole nestling feeding rates appear to have declined since 1995, but this may not be strictly due to reduced insect prey numbers. Montserrat's Orthoptera (including Phasmida and Blattaria) were catalogued. Thirty-seven species were reported for the island, including several new species and at least 16 new distribution records for the island.

Full textAbstract:
The present study focuses on the design of a longitudinal flight controller for an unmanned aircraft equipped with dissymmetric variable-span system (VSMW or Variable-Span Morphing Wing). Its primary role consists in the longitudinal flight stabilization of the aeroplane while in levelled cruise flight, although, it was designed to offer longitudinal flight stabilization for other flight phases as well, such as e.g. take-off and landing. The stabilization algorithm relies on the most up-to-date developments in the state-of-the-art LQR and Batz-Kleinman controller techniques to stabilize the aircraft on its intended longitudinal attitude upon any small atmospheric disturbances inflicted. It was designed for the experimental UAV prototype Olharapo equipped with the VSMW, so it can automatically adjust the VSMW overall wingspan in accordance with the flight speed and stabilize the aircraft in the desired attitude, although, its modular concept allows it to be used for different configurations of the aircraft or even for a different aircraft. The development, simulation and testing of the algorithm were done using the MATLAB® software and the aircraft’s stability and control derivatives previously obtained using the XFLR5® software. Minor adaptations of the flight dynamics equations were performed to allow the compatibilization with the VSMW. The required implementation of imposed flight qualities was also performed to ensure proper scaling the controller weight matrix for optimal values. Finally, the algorithm was tested using three different methods: Classic Disturbances Simulation, Sinusoidal Pitch Variation Test Response and Random Pitch Variation Test Response.O presente trabalho consiste na projeção, programação e teste de um controlador de voo longitudinal destinado a uma aeronave não-tripulada equipada com um sistema de variação dissimétrica da envergadura das asas (conhecido como VSMW, asa dissimétrica ou asa telescópica). Este trabalho tem como principal objetivo desenvolver um controlador capaz de assegurar a estabilidade longitudinal da aeronave em voo nivelado a velocidade de cruzeiro, contudo, este foi também projetado para providenciar essa mesma estabilidade noutras fases de voo tais como a aterragem ou a descolagem. O algoritmo de estabilização baseia-se nas mais sofisticadas técnicas de controlo de voo atualmente disponíveis, mais concretamente LQR e Batz-Kleinman, para estabilizar a aeronave na atitude pretendida aquando da ocorrência de quaisquer pequenas perturbações atmosféricas que afetem a aeronave durante o voo. A aeronave a que se destina trata-se de um protótipo designado de Olharapo equipado com uma asa telescópica que permite ajustar a envergadura total das asas de acordo com a velocidade de voo. No entanto, o conceito modular da estrutura do programa permite que o controlador possa ser utilizado para diferentes configurações da mesma aeronave, ou até mesmo com uma aeronave totalmente diferente. Tanto o desenvolvimento como as simulações e testes do algoritmo foram efetuados com recurso ao software MATLAB® , tendo as necessárias derivadas de estabilidade e controlo iniciais sido providenciadas pelo software XFLR5® . As equações de voo foram devidamente adaptadas para permitirem uma compatibilização com o sistema da asa telescópica e a sua integração nos métodos de controlo LQR e Batz-Kleinman. As qualidades de voo da aeronave foram devidamente definidas e impostas ao controlador para garantir a afinação da matriz de ponderação para valores ótimos. Por fim, o algoritmo foi sujeito a três tipos de testes e simulações: Simulação Clássica por meio de Imposição de Perturbações Atmosféricas, Teste de Resposta a uma Variação Sinusoidal do Ângulo de Arfagem, e Teste de Reposta a uma Variação Aleatória do Ângulo de Arfagem.

La hausse des prix a été particulièrement prononcée dans l’aire urbaine de Marseille-Aix-en-Provence, mettant en relief les limites des catégories et des méthodes d’analyse des marchés immobiliers de l’économie standard. L’apriorisme et les hypothèses anthropologiques de cette dernière ne permettent pas de rendre compte des dynamiques spatio-temporelles des prix. En se fondant alternativement sur les travaux de Simiand et Halbwachs d'une part et sur ceux des néo-ricardiens et néo-marxistes d'autre part, on montre qu’il est plus approprié de recourir aux notions de rente et de valeur d’opinion pour comprendre les mécanismes de formation et de différenciation spatiale des prix. A partir de données désagrégées et localisées à échelle fine sur les transactions immobilières, on identifie alors différents modes de formation des prix qui permettent d’expliquer le paradoxe apparent entre la puissante homogénéisation spatiale des prix et la très grande permanence des hiérarchies spatiales héritées de la période antérieure à l’inflation immobilière que révèle l’analyse spatiale de la hausse. Cette identification des régimes de formation des prix met en valeur le rôle des dispositifs de marché qui, à toutes les échelles, permettent le fonctionnement du marché et garantissent socialement les prix. Ces dispositifs (discours et structures géographiques avant tout) confèrent à certains territoires un rôle assurantiel qui peut exacerber à terme les inégalités inhérentes au modèle d’accession à la propriétéIn the last fifteen years, real estate prices have steeply increased in France, as in other OECD countries. Price increases have been particularly strong in the urban area of Marseille-Aix en Provence, challenging conventional economic categories, analytical methods and interpretations of real estate markets. Apriorism and the anthropological assumptions lying at the core of orthodox economics cannot account for spatial-temporal price dynamics in the Marseille region. By drawing on the work of both Simiand and Halbwachs, and of neo-Ricardian and neo-Marxist economists, this dissertation develops a framework based on the notions of "economic rent" and "opinion value" that provides a better account of price formation and spatial differencing in real estate markets. Different modes of price formation are evidenced using spatially localized, highly disaggregated data of real estate sales: the spatial analysis of real estate inflation helps explain the apparent contradiction between an increased spatial homogeneity of prices and the preservation of pre-existing price hierarchies. Further analysis of price formation regimes highlights the importance of those market devices that allow the market to work and act as price guarantees of a social nature. Such devices (essentially geographical discourses and structures) provide a form of spatial insurance against price decreases that calls into question the legitimacy and sustainability of the 'home ownership for everyone' model

The escalating cost of claims for Noise Induced Hearing Loss (NIHL) in the Canadian Armed Forces (CAF) supports the need to review and upgrade current hearing conservation practices.
The rise of these escalating costs and the need to protect the military personnel when training in extreme noise conditions has initiated an engineering investigation within the Department of National Defence (DND) and in collaboration with the University of Ottawa, to review the existing standards in the field of hearing protection test and evaluation, to propose technical recommendations and to identify the possible technical problems and gaps impacting the quality of the existing procedures.
This study dealt with the estimation of the protection capability of Hearing Protection Devices (HPDs) in the case of high-level impulse noise from small firearms weapons that are a particularly damaging source of noise in military environments, representing an important cause of NIHL.
Testing and evaluation based on a system engineering approach have been used in this work introducing:
- A new testing approach, based on ANSI/ASA S12.42-2010, for testing HPDs when the impulse noise is generated by a small firearm; - A new evaluation approach for HPD performance, introducing a characterization approach using a sub-band analysis for dealing with impulse noise generated by a small firearm.
The effectiveness of HPDs, taking into account the physiological human limitations induced by Bone Conduction (BC), is computed by using an innovative method attempting to better prevent the risk of NIHL when using small firearms.

Ce travail est fonde sur un ensemble de textes prives inedits rediges par le peintre amateur aixois elise chaumery de sorval (1879-1953) et conserves dans les archives de la famille. Deux journaux intimes, l'un tenu a dix-sept ans, et l'autre, de facon occasionnelle, de 1903 a 1933, decrivent l'evolution d'une jeune fille de "la societe" aixoise. Aussi cette etude s'attache-t-elle a montrer les influences culturelles et ideologiques de certains modeles litteraires en degageant les caracteristiques, a la fois originales et conventionnelles, d'une education bourgeoise a la fin du dix-neuvieme siecle. Si l'ecriture intime fut pour elise chaumery le seul moyen d'extorioriser une critique sociale qui ne pouvait se formuler publiquement elle entendait aussi exprimer les sentiments esthetiques ressentis lors des contacts reguliers avec l'art. Cependant, a l'age adulte, l'exercice de la peinture n'ayant pu apporter a cette artiste l'emancipation souhaitee, c'est a la famille, a son passe et a son histoire que celle-ci demande de donner sens a sa vie solitaire. Trois recits prennent alors le relais de l'ecriture diariste pour se constituer eux aussi, suivant des perspectives generiques diversifiees, en "ecritures du moi". On a analyse les themes recurrents de ces ecrits et fait apparaitre leur dimension non seulement ontologique mais esthetique. Les principaux objectifs de cette etude sont donc non seulement de definir le cadre historique, social et culturel dans lequel ces ecritures privees s'inserent, mais de prendre la mesure existentielle voire litteraire de cette volonte feminine d'ecrire, en montrant que l'ecriture mais aussi la peinture ont cherche, modestement, a relier une vie, une memoire et une oeuvre.

Etude d'histoire urbaine, elle analyse la politique d'aménagement de la ville d'Aix-en-Provence de 1850 à 1950. Marquée par le poids des héritages, Aix est présentée comme le paradigme de la ville endormie. L'étude des structures socio-spatiales révèle la trajectoire d'une ville à la démographie atone qui se dote graduellement d'attributs structurants modernes. Le pouvoir local instrumentalise les représentations dominantes de l'immobilisme pour donner de la consistance à une ville-écrin. L'utopie de la "ville d'eaux et d'art" participe d'un projet de reconquête d'une centralité régionale. La planification des années 1920-50 aboutit à un découpage ségrégatif de l'espace. La patrimonialisation des années 1940, initiée par les conservateurs, consacre le nouveau paradigme de la ville culturelle autour du "Viel Aix". Cette réactivation identitaire est contemporaine d'une autre lecture de la ville à connotation sociale. L'explosion urbaine de l'après guerre impose une réponse édilitaire à une crise aiguë du logement populaire et contribue à la naissance de nouveaux territoires en périphérie. Le pouvoir local ignore la troisième ville, celle des hameaux.

Paracetamolio vartojimas yra viena iš dažniausių apsinuodijimo priežasčių daugelyje Europos šalių ir JAV. Šiose šalyse paracetamolio sukelti kepenų toksiniai pakenkimai sąlygoja nemažą hospitalizacijos ir mirčių atvejų skaičių. Apsinuodijimo paracetamoliu gydymas priklauso nuo nurytos paracetamolio dozės, laiko, praėjusio nuo nurijimo iki atvykimo į gydymo įstaigą, bei kitų veiksnių, padidinančių toksinio kepenų pakenkimo riziką. Vyrauja nuomonė, kad ūmaus apsinuodijimo paracetamoliu atveju paciento nurodyta nuryto paracetamolio dozė yra nepatikima informacija tolimesniam paciento gydymui ir priežiūrai.

In these countries paracetamol related liver injuries causes large number of cases of hospitalization and deaths. Treatment of paracetamol poisoning depends on ingested paracetamol dose, the time of admission to the hospital ant the other factors that increases risk of hepatotoxicity. A common perception is that patient-reported dosages are unreliable in the context of acute overdose. Only small number articles concerning the validity of patient reported dose are published. Investigation of the blood biochemical markers and investigation of their changes are important in order to treat the poisoning and prevent liver injuries. Prevalence of paracetamol poisoning is not known in Lithuania. Prevalence of liver injuries caused by paracetamol poisoning is not known as well. The aim of the study is to investigate the changes of blood biochemical markers in patients poisoned by paracetamol. The frequency of analyses of blood biochemical markers was analyzed; levels of blood biochemical markers were analyzed in the different time periods according to the admission to the hospital time and the time after paracetamol ingestion. Levels of blood biochemical markers were compared in the groups of self –poisoned patients and suicidal patients. Calculation of correlation coefficients between levels of blood biochemical markers and patient reported paracetamol dose was performed. In the group of... [to full text]

Full textAbstract:
Spatial patterns as well as temporal dynamics of soil moisture have a major influence on runoff generation. The investigation of these dynamics and patterns can thus yield valuable information on hydrological processes,
especially in data scarce or previously ungauged catchments.
The combination of spatially scarce but temporally high resolution soil moisture profiles with episodic and thus temporally scarce moisture profiles at additional locations provides information on spatial as well as temporal patterns of soil moisture at the hillslope transect scale. This approach is better suited to difficult terrain (dense forest, steep slopes) than geophysical techniques and at the same time less cost-intensive than a high resolution grid of continuously measuring sensors. Rainfall simulation experiments with dye tracers while continuously monitoring soil moisture
response allows for visualization of flow processes in the unsaturated
zone at these locations. Data was analyzed at different spacio-temporal scales using various graphical methods, such as space-time colour maps (for the event and plot scale) and binary indicator maps (for the long-term and hillslope
scale). Annual dynamics of soil moisture and decimeterscale variability were also investigated. The proposed approach proved to be successful in the investigation of flow processes in the unsaturated zone and showed the importance of preferential flow in the Malalcahuello Catchment, a datascarce
catchment in the Andes of Southern Chile. Fast response times of stream flow indicate that preferential flow observed at the plot scale might also be of importance at the hillslope or catchment scale. Flow patterns were highly variable in space but persistent in time. The most likely explanation
for preferential flow in this catchment is a combination of hydrophobicity, small scale heterogeneity in rainfall due to redistribution in the canopy and strong gradients in unsaturated conductivities leading to self-reinforcing flow paths.

Den här uppsatsen behandlar företag som är listade på Stockholmsbörsen som gjorde omvänd split mellan 1995 och 2004. Företagen är testade för abnormal avkastning kring tillkännagivandet av den omvända spliten, samt förändringar i köp-sälj ratio, handels volym och antalet handelsdagar där ingen handel skedde i aktien. Inga abnormala avkastningar eller signifikanta förändringar i köp-sälj ration eller handelsvolymen kunde hittas. Däremot så visar förändringen i antalet handelsdagar utan handel i aktien en försämring och antalet handelsdagar minskade i de aktier som genomgått en omvänd split. Detta medför att likviditeten minskade för de företag som genomförde en omvänd split.
This paper addresses reverse splits for firms trading on the Stockholm stock exchange between 1995 and 2004. The related sample are tested for abnormal returns surrounding the announcement day of the reverse split, as well as any changes in bid-ask spread, trading volume and the number of non-trading days. No findings of abnormal returns or significant changes in either bid-ask spread or trading volume could be found, while the number of non-trading days for the whole sample increased. This may suggest that the marketability decreased for the reverse splitting firms.

A presente dissertação tem como objetivo geral analisar a execução orçamentária da Prefeitura Municipal de Manaus, no período de 1997 a 2000, evidenciando-se as incorreções frente ao conceito de responsabilidade na gestão fiscal estabelecido na Lei Complementar nº. 101, de 04/05/2000 "Lei de Responsabilidade Fiscal". A investigação proposta é de caráter exploratório, justificando-se pela falta de identificação de situações e a construção de cenários referentes ao tema não terem sido muito explorados. Pelo fato da unidade de análise concentrar-se na investigação da execução orçamentária da Prefeitura Municipal de Manaus, este trabalho de dissertação caracterizou-se como um estudo de caso, com uma perspectiva longitudinal, com corte seccional. O período em análise relacionado com a Lei de Responsabilidade Fiscal projetará medidas necessárias, procurando vislumbrar como deverá ser a execução orçamentária, estabelecendo uma prevenção de riscos, e como contorná-los para os próximos exercícios. No decorrer do período analisado, estes mecanismos de execução orçamentária consubstanciados pela aprovação em todas as Leis Orçamentárias permissão para a abertura de créditos adicionais suplementares sem necessidade de autorização da Câmara, pelo excesso de arrecadação, que alteraram substancialmente os orçamentos aprovados. Verificou-se que tal fato ocorreu em função de que a ausência de integração entre o planejamento orçamentário e sua execução possibilitou que as metas incluídas nas propostas orçamentárias fossem apenas instrumentos para justificar os recursos solicitados em cada exercício, por parte de cada Órgão/Secretaria, sem qualquer correlação com a execução orçamentária e financeira durante o exercício. Na medida em que o fluxo financeiro verificado gera um fosso entre o planejamento feito, mais distante ficam do conceito de gestão da responsabilidade fiscal. Assim, conclui-se que em relação a alguns parâmetros básicos da Lei de Responsabilidade Fiscal, não existiram incorreções relevantes na execução orçamentárias da Prefeitura Municipal de Manaus no período analisado.

A técnica de formatação do sinal de entrada foi empregada nesse trabalho para minimizar os efeitos vibratórios sobre uma viga flexível, causados por um atuador tipo motor de passo. A técnica é baseada no cancelamento de pólos do sistema, alocando-se zeros sobre ou próximos aos pólos. A seqüência de acionamento do motor de passo foi projetada de forma estratégica para que o trem de pulsos gerado pelo motor interferisse ao mínimo sobre a viga flexível. Duas estratégias de controle passivo de vibração para a viga flexível foram desenvolvidas. A primeira estratégia alocou um zero sobre o pólo do sistema. A segunda estratégia considerou incertezas sobre os parâmetros do sistema. Nesse caso, dois zeros foram alocados próximos do pólo. Os resultados obtidos pela utilização dessas duas estratégias mostraram que a resposta oscilatória de uma viga flexível pode ser reduzida de forma significativa na amplitude de vibração da viga flexível durante o tempo de observação para a estratégia de controle que alocou um zero sobre o pólo. A segunda estratégia de controle de vibração também reduziu a amplitude de vibração da viga flexível, mas o seu desempenho foi inferior à primeira estratégia devido ao fato que o pólo ainda mantem algum efeito sobre a estrutura. A resposta oscilatória de uma estrutura flexível, quando os parâmetros da estrutura são bem conhecidos, pode ser reduzida consideravelmente sem acrescentar custos adicionais ao sistema.The input shaping technique was employed in this work to reduce the vibration effect at a flexible beam, caused by a step motor actuator. The technique is based on the cancellation of poles of the system by allocating zeros on or near poles. The switching sequence of the step motor was designed in a strategic way so that the vibration produced by the train of pulses generated by the step motor is minimized. Two strategies for vibration passive control of the flexible beam were designed. The first strategy allocates one zero over a pole of the system. The second strategy, considers uncertainness on the parameters of the system. In this case two zeros were allocated near the pole. The results obtained show a significant reduction on the amplitude of the flexible beam during the observation time, for the first strategy. The second strategy also reduced the amplitude of vibration of the flexible beam; but the reduction was less signification due the pole still maintain some effect about the structure. Both results show that the oscillator response of a flexible structure, when the parameters of the system are well-known, can be reduced considerably without adding cost to the system.

Full textAbstract:
This paper delves into the realms of tragedy, memory and representation. Drawing upon the phenomenon of the Phantom Limb and extending it towards a theory of Phantom Bodies, various artworks - literary, theatrical and visual - are examined. After the conflagration of the terrorist attack, how are these absences grieved over and remembered through artistic representation? The essay examines this question by positioning itself amongst the scarred landscapes of post-September 11 New York and suicide bombings in Israel (2000-2006). Furthermore, it investigates whether humanity can be restored in the aftermath of an event in which certain individuals have sought to eradicate it. The fragmentation of the affected body in these scenarios is understood as further complicating processes of grief and remembrance. Artists who reject political polemic and engage with the dimensions of human loss are seen to have discovered means of referring to the absence caused by the act of terrorism. Three such recurring representations present themselves: ash and remnants, presence/absence and memory building. Phantom Bodies are perceived as simultaneously functioning as a reminder of the event itself, insisting upon the response of bearing witness, and as a symbol of the overwhelming power of humanity. Challenges arise when individuals or sections of the affected society deem these artworks to be inappropriate or explicit. Works considered include: Neil LaBute's play The Mercy Seat, Sigalit Landau's art installation The Country, Jonathan Safran Foer's Extremely Loud & Incredibly Close, Spike Lee's 25th Hour, Daniel Libeskind's architectural plans for the World Trade Center site, Eric Fischl's sculpture 'Tumbling Woman', Honor Molloy's autodelete://beginning dump of physical memory and A.B.Yehoshua's A Woman in Jerusalem. The accompanying play, Tales of Ash: A diptych for the theatre, is set in Melbourne, New York and Tel Aviv and deals with life in the face of and after terror. It veers between naturalism, poetic monologue and the epic. Tales of Ash contains two plays. The first centres on Mia, a young sculptor living in New York, who loses both her lover and her creativity on September 11. Upon returning to her home in Melbourne, she finds familial bonds still entwined with guilt and family trauma. The second play revolves around Ilana and Benny, two people living in Tel Aviv, who find themselves suddenly thrust together after a devastating bombing. As they attempt to resume rhythms of life, in the face of all the inherent ferocity of a modern existence in Israel, the struggle between The Ash Woman and The Ash Takers escalates.
