Spills can ocurr during oil productive chain and contaminate various environments due to the toxicity of monoaromatics hidrocarbons. Toluene stands out for being agressive to the nervous sistem and teratogenic, with high mobility and solubility in water, which facilitates environmental impact. Studies show that fungi are potential aromatic compounds assimilators, encouraging new researches about its use on the recovery of contaminated sites. This study aimed to select and characterize fungus with potential for biorremediation of toluene. 50 fungi were selected of the Collection of Microorganisms of Interest for Oil Gas and Biofuels, of UNESP Rio Claro, all of which were isolated from sites contaminated with monoaromatic hydrocarbons. Two trials were realized to select the microorganism with greater potential. The first test evaluated fungal growth under toluene saturated atmosphere. 24 fungi were chosen because its greater biomass production to participate in the next trial, the degradation in plates test, where the blue redox agente, DCPIP, indicates the degradation reaction, turning colorless. From this teste was possible to select one isolate which showed higher growth and stronger medium discoloration as the microorganism with the greatest potential to assimilate toluene. The Trichoderma cf. koningii had its potential evaluated through gas cromatography. The experiment proved the efficiency of the methodology, with positives results from the method validation and the effectiveness demonstrated of the LA-PHA-PACK bottles to prevent the volatilization of toluene during the 21 days of experiment. Being reliable its use for monitoring toluene decay associating it with degradation. This results are important because there aren't many methodologies and vials efficient to the purpose of this work. In the present study the degradation rates demonstrated no significant decay of the concentration of hydrocarbon. That may be related to the...

Sabendo-se do potencial de toxicidade do mercúrio, mais especificamente de sua forma orgânica, o metilmercúrio (MeHg), faz-se necessária a busca por métodos analíticos eficientes e precisos para a determinação e especiação do metal. A técnica de difusão por gradiente em filmes finos (DGT) já vem sendo utilizada para tal fim de maneira eficiente tendo apresentado resultados satisfatórios em diversos estudos. Porém, a utilização de ligantes alternativos aos convencionais, que tornem a aplicação da técnica menos custosa em termos laborais e financeiros, faz-se importante para um monitoramento constante e eficiente do metilmercúrio no ambiente. No presente trabalho buscou-se avaliar o potencial da levedura Saccharomyces cerevisiae imobilizada em agarose em combinação com a poliacrilamida como agente difusivo para determinação seletiva de MeHg. Os resultados demonstraram-se positivo, com um coeficiente de difusão médio de 7,03 ± 0,77 x 10-6 cm2 s-1. Os resultados demonstraram também baixa influencia do pH, força iônica e outros íons na retenção do analito pelos dispositivos. As recuperações de Hg2+ demonstraram-se insatisfatórios, evidenciando a seletividade dos dispositivos

Os processos de decomposição dos resíduos sólidos resultam em uma importante fonte de poluente tóxico, o percolado, usualmente denominado de chorume, podendo causar graves impactos ambientais em ecossistemas vizinhos, se não for drenado e tratado adequadamente. No tratamento eletrolítico de efluentes aquosos, os poluentes sofrem degradação oxidativa. Visando o tratamento do percolado de aterro sanitário, foram analisados os parâmetros de pH, temperatura, DQO, condutividade, amônia e absorbância, utilizando-se de uma densidade de corrente de 125 mA.cm-2. As regas na espécie Helianthus annuus L., girassol da família Asteraceae, foram realizadas durante 95 dias com 11 tratamentos do percolado bruto e tratado em concentrações de 25, 50, 75 e 100% de percolado com a adição de Na2SO4, esta última concentração também sem adição de Na2SO4, a fim de avaliar a sobrevivência e o crescimento dessa espécie. Ao final do experimento, os valores de crescimento mais expressivos foram para o percolado 100% sem Na2SO4 mostrando que: a altura total obteve uma diferença em 27% menor no tratado; o diâmetro da base do caule mostrou uma diferença 45% menor do tratado em relação ao bruto; o número de folhas foi de 65% menor e área foliar de 51% menor do tratado em relação ao bruto, indicando que mesmo em crescimento o Grupo Tratado permaneceu menor durante a maioria das medidas das variáveis biométricas do girassol BRS 323. Todos os vasos regados com chorume tratado tiveram uma redução no peso seco das partes aéreas, chegando a uma redução média de 72% na concentração 100% de chorume sem a adição de Na2SO4

A preocupação com a saúde e bem-estar atinge uma maioria de indivíduos, atualmente a busca por uma vida mais saudável faz parte do dia a dia de grande parte da população. Para alcançar uma boa qualidade de vida diversos aspectos devem ser considerados. No ambiente de trabalho a qualidade de vida tem sido afetada em consequência da utilização cada vez menor das potencialidades corporais dos indivíduos. Em contrapartida, a atividade física proporciona benefícios à saúde dentro e fora do ambiente de trabalho. Assim, o objetivo desse estudo foi identificar a associação entre qualidade de vida no trabalho e sua relação com o nível de atividade física dos funcionários administrativos da Unesp de Rio Claro - SP. A análise dessa associação pode auxiliar no enriquecimento de técnicas para intervenção e promoção da saúde, podendo aumentar a qualidade de vida no trabalho. Para a coleta dos aspectos psicossociais dos participantes foi aplicado um Questionário de Avaliação de Qualidade de Vida no Trabalho em Instituições de Ensino Superior em 136 funcionários administrativos (exceto docentes e trabalhadores de manutenção). Esse questionário avalia 7 domínios em 2 blocos: bloco 1 avaliação de desempenho, bloco 2 avaliação de frequência. Além disso, foi utilizado o questionário de Baecke adaptado por Florindo et al. (2004), para acessar o nível de atividade física. Medidas antropométricas foram coletadas para dados sobre a composição corporal dos participantes. Para coleta de dados sobre os aspectos socioeconômicos foi utilizado o questionário Critério de Classificação Econômica do Brasil proposto pela Associação Nacional de Empresas de Pesquisa (ANEP - 2003). Os resultados demonstraram que a maioria dos funcionários é Moderadamente ativa (58,1%) e na maior parte dos domínios da qualidade de vida no trabalho associados com nível de atividade física os resultados foram indesejáveis...

Assessment is a theme explored in various areas of human performance, particularly for the analysis of an athlete performance and/or all team members in game situation. Assessment requires different tests and models to quantify strengthens and weaknesses of an athlete and of the team. With that in hand, it is possible to develop an intervention program, with consequent improvement of techniques and tactics play systems. The present study aimed to identify, in the literature, the athlete's performance ratings and of the team in game situation for team sport. Based on the literature review, we propose a set of variables to include in an instrument for basketball performance assessment. The methodology for the present study involved a collection of materials, including scientific articles, books, websites, academic papers. The present research comprises the concepts and definitions related to: team sport; the relevance of game analysis and its development; the advantages and disadvantages of different assessment techniques, particularly in team sports; and lastly, the instruments used for assessment in the context of team sport athletes. From the literature review we propose a set of variables that may be useful to consider in an assessment instrument for basketball performance

Several methods are used towards delayed onset muscle soreness appraisal. This study's goal was to investigate, amongst three commonly adopted methods, which one would be the most effective (the one that shows higher values) in the quantification of this phenomenon. 10 male subjects, of age 22.8 ± 3.1 years old, weight 80 ± 12.4 kg, height 174 ± 0.07 cm, without recent experience with strength training (lower limbs) and/or running took place in this study. All subjects carried out a muscle damage induction protocol, which consisted of 30 minute downhill running (-16% or -9.09º) at 80% speed compared to their maximum oxygen consumption. Muscle damage determinants such as isometric peak torque, knee joint range of motion and circumference of the medial portion of the thight were measured before, during, 24, 48, 72 and 96 hours after downhill running. The subjective pain perception was measured simultaneously with the other determinants through three different tests: sitting on and getting up of a chair; climbing and descending from a 45cm step; and self thigh palpation. After going through all subjective pain perception tests, the subjects filled out a visual analog scale with their perception of pain. Muscle damage changes over time were compared through variance analysis (ANOVA) one way for repeated measures. Subjective pain perception values obtained in all three different tests were compared through two way ANOVAs for repeated numbers. The significance level adopted in this study was z ≤ 0.05. The results showed that the step test was the on which better evaluated the delayed onset muscle soreness. No significant differences were found through the ADM and CIR recovery markers. Downhil running determined reduced of PTI (~22.4%). Significant links between pain were obtained for both subjective pain perception tests starting at 24 and 48 hours, where the highest registered average happened in the step test after 48h, with high...

Considering the importance of zoonotic infections by Leishmania spp. and Toxoplasma gondii in Araçatuba region, São Paulo, this study determined the degree of knowledge of residents of Araçatuba about these two diseases. Questionnaires about these diseases were applied to 123 people. Regarding schooling, all the respondents were literate, and 69.9% (86/123) did not attend higher education and 30.8% (37/123) completed an undergraduate degree. Of these, 91.9% (34/37) knew the meaning of the term zoonosis, with significant difference compared to those who were not trained. This word was unknown by 57% (29/123) of total respondents. Most non-graduates, 59.3% (51/86) did not know what is toxoplasmosis and among graduates, 35.1% (13/37) ignored the subject.There were significant difference between these groups. Regarding the prevention of Leishmania infection, a greater proportion of the residents advocated environmental cleanup, the collar repellent and use of citronella. In relation to toxoplasmosis, 54.5% did not know the ways of transmission of this disease and among those with graduate degree, 13 ignoring any transmission medium. When it comes to prevention of this disease, 55.3% (68/123) did not know any prophylactic. In the group of higher education, 14 did not know how to prevent toxoplasmosis. The results of this study show that the majority of respondents are not aware about the mode of transmission of these diseases, especially in relation to toxoplasmosis.

Considering that the current pedagogical project for the Dentistry course at FOA-Unesp was structured in 2001, a year before the national resolution that introduced the new curricular guidelines for the dental field, the aim of this study was to analyze critically this document and assess the academic perception of the pedagogical project, as well as the current curricular structure. A previously tested and validated semi-structured questionnaire was used to obtain the needed information, and a documentary analysis was conducted. The questionnaire was drafted based on data from the National Curricular Guidelines (DCN) and Unified Health System (SUS) guidelines. The sample consisted of almost all the graduating students of 2007 (n = 61). Of these, 95% had no knowledge of the pedagogical project for the undergraduate course; 53% found the integration between the disciplines offered by the course insufficient; 66% pointed out that there was duplication of the revised contents; 41% said that the interdisciplinary relation was unsatisfactory, and 67.2% said they preferred the modular system of teaching. Furthermore, 55.7% of the students said that that the course does not fully cover the principles of completeness and resolution of actions, and 37.7% pointed out that clinical care was not humanized. As for the competence and skills needed to exercise the profession, the students admitted feeling secure about carrying out preventivecurative clinical actions, and feeling insecure about developing broad ranging actions, like managing and planning. Analysis of the documents showed a certain disagreement in the organization of the pedagogical project and the curricular structure, when confronted with the course of action set down by the National Curricular Guidelines. The data prove the urgent need to restructure the FOA-Unesp curriculum and confirm the importance of a continuous evaluation in higher education.
