The region Indiara (GO) is located in southwestern of São Francisco Craton in the Internal Zone of the Brasília Belt, western part of the Tocantins Province. In this locality outcrop rocks of the Goiás Magmatic Arc. These rocks are muscovite gneiss with biotite, muscovite-biotite gneiss, biotite gneiss with muscovite and garnet, biotite-muscovite gneiss, muscovite porfiroclastic gneiss, biotite porfiroclastic gneiss, muscovite-quartz schists, garnetquartz schists, and metamafic rock (hornblende schists) as metric or kilometric lenses. The gneisses have granodioritic composition, granoblastic texture, with some portions with lepidoblastic texture, constituting a discontinuous centimeter to millimeter banding; the structure is anisotropic, marked by the preferred orientation of all the minerals. These gneisses are leucocratic, generally are inequigranular and fine to medium grained. The hornblende schists have nematoblastic texture, are inequigranular and fine to medium grained and have anisotropic structure that is given by a foliation, marked by a strong preferential orientation of the crystals of amphibole and other minerals present in the rock. The gneisses of the area are composed of plagioclase (oligoclase/andesine), quartz, microcline, muscovite, biotite, epidote, apatite, zircon, garnet, kyanite, oxides and hydroxides of iron and opaque minerals. And the metamafic rocks of Indiara region are composed mainly of amphibole, plagioclase (oligoclase/andesine), quartz, titanite, biotite, allanite, garnet, oxides and hydroxides of iron, apatite, epidote, rutile, muscovite and opaque minerals. At least three phases of deformation were observed in the rocks of area of study (Dn-1, Dn and Dn +1). The Dn phase and represented by a well-marked foliation Sn having low dip angle (average dip of 20 °) and dip direction to SW (210/21) and to NE (18/20); the Dn-1 phase is represented by a compositional banding (Sn- 1), this banding is generally...

Obesity is characterized by an excess of fat on the body and can results several problems on the individual health. As an epidemic of modern times, the prevalence started to increase at an accelerated rate from the 90's in worldwide. Data on the epidemic in Brazil and medium-sized cities are scarce, and the monitoring of obesity is essential for development public policy. So, the objective was to analyze the individual factors associated with obesity such as age, gender, education, marital status, economic class and level of physical activity and make a monitoring of obesity in adults in the city of Rio Claro - SP. To do this, the survey was conducted longitudinally, consists of two times at an interval of seven years. At first (2008) were interviewed 1588 adults in the city of Rio Claro distributed throughout the city. At the second phase (2014/2015) was conducted a new interview with the same subject in 1588. In 2008, personal information collected and applied some questionnaires with the physical activity level, food intake and quality of life. To assess obesity in adults was calculated the body mass index (BMI) proposed by the World Health Organization (WHO) from the high reported weight and height. For older people it used a specific BMI. The prevalence was used percentages and their respective confidence intervals of 95%. For the incidence, was calculated by the formula of cumulative incidence, both stratified by personal characteristics (gender, economic class, education, marital status and age). Thus it was observed that there was an increase in the prevalence of obesity in 2008 (19.0%), increasing to 26.7% in 2015. The cumulative incidence was 14.4% in the range of 7 years. As for the groups, we observed a significant difference between economic class and obesity being less prevalent among people of class D / E. Regarding marital status, it was observed that married / cohabiting have a higher prevalence. Therefore, we can conclude...

Mastitis is an acute or a chronic inflammation of the udder, represented for physical, chemical and bacteriological milk alterations. It is notable that ovine milk represents high economic importance, and it can be used in the production of cheeses and other derivates, contributing for the farmer’s recipe enlargement. However, the mastitis in animals can determine the reduction of milk quantity and quality in infected animals. This may determine lambs’ weight loss and increase animal’s mortality. By the other hand, considering Public Health issues, mastitis can cause milk nutrients losses and promote the microorganisms’ multiplication that may lead to diarrheas and to other zoonosis in humans. This study aimed to evaluate 159 sheep mastitis status in 20 small farms located in Bauru (SP) region. Of the 309 colected samples, in 97 (31.4%) were isolated microorganisms of the genus Staphylococcus sp., which them 27.5% being coagulase negative Staphylococcus and 3.9% coagulase positive Staphylococcus. Of 177 isolates, 97 (54.8%) were represented by the genus Staphylococcus sp., which them 57 (58.8%) from pure culture and 40 (41.2%) in association. Most agents isolated were sensitive to antibiotics used in the test. Thus, we could verify the isolation of infectious microorganisms such as coagulase positive and negative Staphylococcus and, as well in dairy cattle, preventive measures to obtain hygienic milk are extremely important in order to get a final product with quality and safe in food and microbiological point of view.

O objetivo do desenvolvimento sustentável vem sendo buscado no Brasil desde a década de 1980, por ocasião da promulgação da Política Nacional do Meio Ambiente (Lei n. 6.938, de 31 de agosto de 1981). De lá para cá, e após a Conferência das Nações Unidas sobre o Meio Ambiente e o Desenvolvimento, também conhecida como ECO-92, Rio-92, Cúpula ou Cimeira da Terra, diversas políticas ambientais têm sido elaboradas sobre temas, desdes os mais tradicionais e clássicos (recursos florestais, recursos hídricos), até os mais recentes (resíduos sólidos, remueração de serviços ambientais). Este trabalho se propõe a apontar, descrever, sistematizar e selecionar alguns dos principais parâmetros que devem ser considerados, dentro de uma leitura predominantemente econômica, para efeitos de se avaliar e monitorar as políticas públicas na área ambiental. Como hipótese principal, defende-se que é possível indicar critérios que possam orientar a avaliação e acompanhamento das políticas públicas ambientais por parte dos distintos segmentos da sociedade e segundo diversos interesses específicos. Pretende-se utilizar o método indutivo para fins de se estabelecer uma conclusão que confirme ou afaste a hipótese principal deste trabalho. Foram identificados, ao final, alguns dos principais parâmetros que poderiam auxiliar, os segmentos da sociedade direta ou indiretamente envolvidos em determinado tema ambiental, a discutir, avaliar e monitorar os instrumentos de comando e controle, econômicos e outros consoante propostos para a implantação de um política pública ambiental.

The aim of this study was to analyze the behavior of the flow of heat (temperature) through the thickness of panels LVL (Laminated veneer lumber) produced with phenol formaldehyde adhesive, in laboratorial and industrial scales. Experimental program was conducted with five LVL panels (three produced in laboratorial scale and two in industrial scale) with different arrangements of a mix of commercial veneers from tropical pinus from the south region of Sao Paulo State, Brazil, bonded using phenol formaldehyde adhesive. The temperature inside the panels during the pressing process was evaluated using thermocouples type T (cooper-constantan), installed mostly in the center of the glue lines and connected to a data acquisition system. The graphics of temperature as a function of the time showed a gradual increase of temperature up to pre-set values, remaining constant from them. The temperature reached at the center of the panels was adequate to promote the curing of the adhesive. These pre-set values were similar to the minimum values presented by other authors and manufacturers of these adhesives that affirm that temperatures above 100ºC at the center of laminated panels bonded with phenolic adhesives are sufficient to ensure proper cure of the resin. The time necessary for curing of the adhesives confirmed the validity of practical expressions provided by adhesive manufacturers.

A água é um recurso vital para a existência de todos os organismos vivos, e a captação para uso doméstico, produção agrícola, mineração, produção industrial, geração de energia, atividades de lazer e práticas florestais podem levar à deterioração da sua qualidade, atingindo o ecossistema aquático e também a disponibilidade de água potável disponível para consumo humano. O presente trabalho teve como objetivo monitorar a qualidade da água do Córrego Chumbeadinha no município de Ourinhos-SP, que perpassa pela área urbana da cidade e é desprovido de mata ciliar em quase todo seu percurso, além de sofrer dois represamentos artificiais. O Córrego Chumbeadinha é um afluente de segunda ordem do Rio Paranapanema, percorrendo cerca 4 km de sua nascente até sua foz. Foram realizadas amostragens das seguintes variáveis: Sólidos em Suspensão, pH, concentração de oxigênio dissolvido, condutividade elétrica, temperatura da água, coliformes fecais, transparência da água, além do cálculo do índice de estado trófico, em quatro locais no curso do córrego, de setembro de 2009 a abril de 2010. Dessa forma, o córrego Chumbeadinha nasce com uma qualidade boa, apesar de sofrer forte pressão da expansão urbana, porém os demais pontos foram classificados como eutróficos, sendo registrada a presença de coliformes fecais em todas as amostragens. A falta de vegetação nas margens do lago pode ser a grande causadora da eutrofização, pois os sedimentos não encontram dificuldades para chegar até o curso d'água, assim interferindo diretamente no IET do lago.
