Este estudo analisa o periódico Educação Física - Revista de Esporte e Saúde, objetivando levantar algumas questões sobre a produção de conhecimento e a organização profissional do campo Educação Física no Brasil. Como metodologia de trabalho utilizou-se a análise do discurso tendo como fonte primária o próprio periódico. Gerada em séculos anteriores por ginastas, desportistas, educadores, filósofos, militares, médicos, entre outros, a educação física está pronta para dar os seus primeiros passos no século XX

Naturally characterizes the human being the interference in the environment to ensure their survival and also convenience. After numerous environmental accidents caused by unbridled pursuit of this goal, the concern about providing for current needs without compromising the ability of the future generations to supply their own, gained space. In order to contribute to sustainable development the Life Cycle Assessment (LCA) was implemented. This tool is based on the concept that if the environmental impacts of a product or service are known, it is possible to take better decisions concerning its environmental aspects. The purpose of this research is to conduct the LCA of polyvinyl chloride (PVC), the world’s second most consumed thermoplastic. The methodology described in NBR ISO 14040 and NBR ISO 14044 was followed. As a result, the LCA of polyvinyl chloride produced in Brazil was obtained, and, therefore, the inventory of the product in question adapted to Brazilian reality. The research can be applied to various studies considering that actions were taken to ensure that it represents the Brazilian reality. Moreover, the procedures were described to guarantee the greatest transparency possible

O manejo integrado de pragas vem ganhando cada vez mais espaço no agronegócio brasileiro, sendo importante em métodos de controle que visam a sustentabilidade na agricultura. Atualmente tem-se aumentado cada vez mais a demanda por defensivos agrícolas naturais, que sejam economicamente e ecologicamente viáveis. Analisando-se as espécies pragas recentemente introduzidas no Brasil, encontra-se Zaprionus indianus Gupta, 1970, popularmente conhecida como mosca-do-figo. Este drosofilídeo tem apresentado um alto potencial de infestação, sendo um organismo limitante à ficicultura e que causa grandes prejuízos econômicos a seus produtores. Dentre as diversas formas de controle de pragas, podem ser citados os bioinseticidas como o Nim (Azadirachta indica), o qual apresenta baixa toxicidade em relação aos inseticidas químicos, e que vem despertando interesse devido as suas propriedades e seu potencial como inseticida natural. Sabendo-se da urgente necessidade em controlar essa praga, o presente trabalho estudou os efeitos da interação de óleo de Nim, da marca comercial Próneem Plus sobre o desenvolvimento populacional de Z. indianus. Os testes foram realizados com indivíduos da F1 - adultos e imaturos - oriundos da criação de Z. indianus, no Laboratório de Entomologia I do Departamento de Zoologia, UNESP – campus de Rio Claro. Foram realizados quatro diferentes experimentos, considerando o potencial bioinseticida e de repelência do produto, testando-se as concentrações de 0,5; 1,0; 1,5 e 2% sob condições de laboratório e as concentrações de 0,35; 0,5 e 0,75% em monocultura de figo. O óleo de Nim apresentou atividade inseticida para a fase larval de Z. indianus, nas concentrações de 0,5; 1; 1,5 e 2%, causando elevada mortalidade e retardando o desenvolvimento da espécie, porém, não apresentou toxicidade significativa...

Art can be understood as a process in which knowledge is used to perform certain skills. From Latin ARS, technical means and / or ability, in Greece, there was the word art, but "Tekne", which originated from the word "technical." So art and technique are present in sculptures, paintings, shoes or ships. In this sense, designers, engineers and all professionals who use technology can be called artists. Considerations must be made regarding the level of energy embedded in the material from its production until its use, even considering recycling, sustainability and life cycle of materials. This study aimed to present the use of scanning technology and 3D virtual modeling and its application in prototyping with CNC (Computed Numerical Control) as a tool in current use cutting-edge courses in arts, design and engineering and their relations with sustainability.

This research has as main objective the analysis of the auto industry has done to reduce disposal of solid waste in its production process as much as to facilitate the recycling of cars after they complete their life cycle. Despite the auto industry is not one of the most polluting in terms of its production process, it produces a good that is causing major pollution. In despite of the great current concern in seeking to reduce the emissions of pollutants by vehicles, as important as the quest for cleaner fuels is the study of how to dispose of old cars. Even if the car production does not increase significantly each year in relative terms, we must consider the fleet of used cars that still circulates in the world. Ending the mammoth “cemeteries” of automobiles, however, it is not so easy, even because the car is composed of various materials, which in many cases are not easily separable. In addition to an overview, the research seeks to examine the possible advances in Brazil related to the process of auto recycling

The article aimed to understand the concept of leisure and understanding that older people have about their benefits to the quality of life as part of the idleness of the population. We used a sample of subjects living in the city of Bauru, SP, aged less than fifty years, of both sexes and economically disadvantaged class. It was used in literature, documentary and field. We developed an intervention project that aimed to education for leisure. It was the conclusion that public policies are necessary and qualified professionals for construction projects and equipment to expand the Recreation, spreading it and reaching the people of old age since previous stages of life. Materials with simple and low cost, the project of intervention, it reached the recreation-education and education for leisure satisfactorily.

The aim of this study was to report the occurrence of Anaplasmataceae-like organisms in monocytes from the hybrid surubim catfish. During the hematological evaluation of fish infected by Pseudomonas sp. in a fish farm located in the State of Mato Grosso do Sul we observed into the monocytes the presence of numerous pleomorphic inclusions of various sizes, rough in appearance which presented basophilic staining. These inclusions were similar to elementary bodies, initial bodies and morule of the bacteria from Anaplasmataceae family, often diagnosed in domestic mammals. This is the first report of its occurrence possibly belonging to the family of Anaplasmataceae in cultured fish in Brazil. Additional studies are necessary for molecular characterization of this bacteria, pathogenic potential, life cycle and impact on the intensive production of fish.
