The traffic of wild animals can be identified as the main cause of finding captive animals in zoos and sorting centers in Brazil. The maintenance of these animals in captivity is usually justified by the prevention of total loss of individuals of that specie, if it becomes extinct in the wild, and also, the importance of these subjects in studies of basic biology of the species. Keeping animals in captivity environment brings the need to ensure the welfare of them. The high population density and limited space are some of the possible stressors that these individuals face in capivity. Even the low pressure feeding and food easily available could be stressors, since they change the budget activities typical of the specie, causing sedentary behavior and sometimes depression. The captive environment and activities related to it (handling, transport, social change and social isolation) could compromise the animal welfare. Reduction in life expectancy, impaired growth and reproduction, personal injury, illness, immunosuppression, exacerbated adrenal activity and abnormal behavior, are events often lonked to compromised welfare. Hence, assessment and promoter methods are used to provide the welfare to captive animals. The assessment can be made by hormonal and/or behavioral measures. Both are extremely important, and usually are used in combination, to provide more tangible results about the condition of the animal. The promotion of animal welfare can be accomplished through environmental enrichment, a technique which aims to provide a more complex and diverse environment, increasing the possibility of the animal express more natural behavior, or characteristic of the species. Thus, the objective of this dissertation is discuss the importance of animal welfare and the ways this can be evaluated and promoted... (Complete abstract click electronic access below)

O presente trabalho de conclusão de curso reporta os resultados obtidos durante o estágio de Iniciação Científica realizado no Núcleo de Biossíntese, Bioensaios e Ecofisiologia de Produtos Naturais do Departamento de Química Orgânica do Instituto de Química da UNESP-Araraquara. Foram realizados ensaios de triagem de substâncias naturais, semissintéticas e sintéticas com atividade inibitória sobre a protease aspártica pepsina e a protease serínica subtilisina. As amostras foram obtidas de extratos vegetais e de fungos endofíticos e foram testadas tanto substâncias puras naturais como diterpenos clerodânicos, cromenos, peptídeos e amidas bem como derivados sintéticos do ácido caféico, ferúlico, alcalóides piridínicos, entre outros resultantes das pesquisas realizadas por pesquisadores do NuBBE. Resultados mostraram que os ensaios de inibição da pepsina e da subtilisina apresentaram seletividade para os diferentes tipos de substâncias testadas. Ainda mais, foi possível observar diferenças nos resultados obtidos com os enantiômeros dos cromanos e dos cromenos. As substâncias que apresentaram maiores porcentagens de inibição foram os cromenos, os derivados do ácido cafeico, do ácido ferúlico e do ácido benzóico, as amidas, bem como os diterpenos clerodânicos. Alguns destes resultados foram publicados em revistas indexadas (Flausino et al., 2009; López et al., 2010; Oliveira et al., 2011) e outros estão sendo preparados para publicação

The increasing demand for alternative fuels lead to the search for solutions to use these fuels in old equipments and bring for new equipments the necessity of alternative fuels based burners. As a solution for these necessity the Gas Interchangeability`s studies came in evidence, because it studies the possibility of changing one fuel for another without changing the initial condition. In integrated industries, as most of steel industries, there is a link between process, the byproducts of one process are used as fuel for other process. There are new conditions for the equipments, that will be developed for these fuels, but even in these industries there will be situations which the byproduct won`t be available, and the process cannot stop. Using the gas interchangeability`s concepts is possible to work with security in both cases. Using alternative fuels in fossil fuel based burners and having a back-up solution for new technology burner. But using these new solutions were verified that there are some cases which the interchangeability`s methods does not work with satisfactory results, and for this reason, this study came to develop a new concept for the Method of Wobbe Index to evaluate the possibility to increase the range of the satisfactory results

O trabalho buscou investigar como uma revista de grande circulação entre os professores do ensino básico trata a questão da relação entre escolafamília. O motivo pelo qual buscamos pesquisar sobre o assunto é o fato dos professores recorrerem a este tipo de material, que acaba normatizando a sua prática. No entanto, será esta leitura adequada? Qual a real contribuição da revista? Fazendo uma comparação com a literatura científica o que poderemos constatar? Como metodologia foi feita uma análise documental das Revistas Nova Escola durante os últimos 5 anos, do período de junho de 2006 à junho de 2010. Analisou-se todas as revistas correspondente ao período indicado e selecionado somente os artigos que falavam sobre a relação escola-família. Posteriormente foi feita uma análise quantitativa e qualitativa dos artigos através da Análise de Conteúdo dos mesmos, analisando os dados à luz do embasamento teórico sobre o assunto, fazendo uma comparação com a literatura. Observou-se com a pesquisa que embora a quantidade de reportagens abordando o assunto família-escola fosse em pequena quantidade, eram muito coerentes e continham embasamentos teóricos indiretos.

In Brazil, the football is more than just a sport, it's a passion and part of country's DNA almost a century ago. By this prerogative the club national championship, nowadays known as Brazilian Championship and organized by Brazilian Football Confederation, it is a mark in this modality. During the soccer history, were made several changes of nomenclature, rules and dispute mode, that generated many controversies, contributing for discussing about credibility of the championship. There were many changes about dispute mode, alternating the mixed mode (eliminatory + classificatory and vice versa) and a dispute mode based on classification. This research aimed to described and to analyzed the changes that have occurred in dispute types of the Brazilian Championship, series A, in the last 15 years (1995 to 2010). It was analyzed each edition, with data like average of public, matches and participants number, period that the championship was conducted, beyond the dispute mode. In the last 15 years, have been used five different types and it was observed that the current mode to consecutive points is the most appropriate, because this mode showed the best public average, greater coherence to elect the competition champion and this mode also encouraged the clubs about planning, organization and professional management. This issues contributed to a significant improvement in quality of Championship

É notória a crescente preocupação com os aspectos éticos e morais quando se refere à Educação no Brasil. Não poderia ser diferente com a Educação Física escolar, já que se trata de um componente curricular obrigatório dentro da Educação Básica. Apesar da tentativa crescente de conscientização da importância dos valores enquanto conteúdos explícitos na educação formal, não se têm claro quais deveriam fazer parte do planejamento dos professores. Esta pesquisa teve como objetivo geral realizar um levantamento de artigos em periódicos científicos da Educação Física que abordassem valores e atitudes presentes na disciplina. Em outras palavras buscou-se mapear e analisar quais valores e atitudes são esses na Educação Física, no contexto escolar. Para a seleção dos periódicos científicos analisados, foram seguidos os seguintes critérios: revistas específicas da Educação Física; trabalhos propostos à publicação julgados por pareceristas; acesso tanto ao resumo quanto ao trabalho na íntegra; acesso a todos os números das revistas publicados entre os anos de 1998 e 2007. A análise quantitativa constatou que o número de artigos científicos que abordaram o tema valores e atitudes nos últimos dez anos foi pequeno. Entre aproximadamente 1000 artigos analisados, foram localizados apenas 40 artigos. Apesar do número reduzido de artigos, observou-se uma tendência no aumento das publicações a partir de 2002, seguindo tendência da área da Educação. Valores como alteridade, socialização, voluntariedade, estética e saúde apareceram nos artigos analisados. O tema de valores e atitudes é discutido na produção científica da Educação Física, embora ainda de forma incipiente, e os temas analisados são bastante abrangentes.

2,25Cr-1Mo alloy steels are widely used in petrochemical plant equipments working in high temperature conditions because of their good mechanical proprieties in these conditions. Although, when exposed for a long time at high temperature, in the rage of 343 °C to 593 °C, may present the temper embrittlement phenomenon. The component named stripper of assembly converter of fluid catalytic cracking unit (UFCC) of studied plant is manufactured using this material, which is subject to temper embrittlement. The phenomenon of temper embrittlement refers to progressive lose of toughness, making the material brittle. With embrittlement, equipaments manufactured with this material are under risks to suffer brittle fracture in the cool down and start-up situations of them, which can cause catastrophic failures. By this reason, this research studies presence of temper ebrittlement phenomenon on this material. To verify the toughness of the material is conventionally used charpy V-notch test. However, this test requires the removing of samples of the material to make specimens. This fact becomes critical when talk about structural components of an equipment. So, this research also studies a non-destructive test that can be executes in-situ, known as instrumented indentation, as an alternative detection of the phenomenon at the component stripper, by comparative of the mechanical proprieties obtained by conventional tests in similar samples

The relationship between the microstructure and the magnetic properties of soft magnetic materials, have been studied by different researchers who seek to employ electrical systems, increasing their life span and reduce their energy consumption. Following this same line the Brazilian Synchrotron Light Laboratory developed a new synchrotron light source, the Sirius, where magnetic materials with high magnetic permeability values are being studied for use in accelerator dipoles. The low carbon steel is a ferromagnetic material that has a great relationship between cost and magnetic permeability. Aiming to raise the values of permeability of the material, heat treatments were done and evaluated the magnetic properties, microstructure and mechanical properties to correlate them. It was noted that the thermal annealing were the most effective, and the annealing performed with a small time threshold, which only phenomenon observed was the primary recrystallisation, was the most elevated values of magnetic permeability of the material, due to the average grain size ideal achieved. The heat treatments do not guide the magnetic domains of the material and not influence the mechanical properties of the material due to lack of carbon in the microstructure. The annealing treatments were shown to be an alternative to raising the values of the magnetic permeability of the material and facilitate the implementation of ultra low carbon steel in the dipoles of Sirius

Kinematics is the geometry of motion, including displacement, speed and acceleration, without considering the forces acting over a body. The use of kinematics is still very limited when we are evaluating dogs because of the high cost of the equipment, but the information obtained is objective and precise, what is essential for a trustful evaluation. Taking all this into consideration, this evaluation will describe some researches that used the method, specifying the final objective for each of them. By this analysis, we can conclude that kinematic studies, according to the characteristics of dog races, are necessary to explain how body structure and conformance may affect the function. Besides that, according to normative patterns of a population it is possible to study some diseases and treatment evolution
