This study aimed at evaluating the effect of collect time (day and night) on ant fauna attracted to baits in areas of Eucalyptus cloeziana (Myrtaceae) and cerrado. The ants were collected in Fazenda Boa Vista, Mannesmann Fi-El Florestal Ltda, Paineiras, Minas Gerais State. Eigthteen sample units were collected: 12 in E. cloezina and six in cerrado. Each sample unit consisted of three plots (25 x 35 m each). The plot consisted of 34 baits distributed in a grid pattern at 5 m intervals. The sampling was carried out in the diurnal and nocturnal period. The results obtained revealed that both type of vegetation (cerrado x Eucalyptus) and the collect time (day x night) had a significative influence on the epigaeic ant fauna. The ordination (DCA) indicated that collect time effect was more important to fauna structuration than the vegetation effect. Brachymyrmex sp.1, Brachymyrmex sp.2, Camponotus crassus Mayr, Camponotus rufipes (Fabricius), Cephalotes pusillus (Klug) and Ectatomma brunneum Smith were indicator species of nocturnal period, and Camponotus renggeri Emery, Camponotus atriceps (Smith), Camponotus melanoticus Emery and Paratrechina sp.1 were indicators of nocturnal period.

This study evaluates the influence of different cartographic representations of in-car navigation systems on visual demand, subjective preference, and navigational error. It takes into account the type and complexity of the representation, maneuvering complexity, road layout, and driver gender. A group of 28 drivers (14 male and 14 female) participated in this experiment which was performed in a low-cost driving simulator. The tests were performed on a limited number of instances for each type of representation, and their purpose was to carry out a preliminary assessment and provide future avenues for further studies. Data collected for the visual demand study were analyzed using non-parametric statistical analyses. Results confirmed previous research that showed that different levels of design complexity significantly influence visual demand. Non-grid-like road networks, for example, influence significantly visual demand and navigational error. An analysis of simple maneuvers on a grid-like road network showed that static and blinking arrows did not present significant differences. From the set of representations analyzed to assess visual demand, both arrows were equally efficient. From a gender perspective, women seem to took at the display more than men, but this factor was not significant. With respect to subjective preferences, drivers prefer representations with mimetic landmarks when they perform straight-ahead tasks. For maneuvering tasks, landmarks in a perspective model created higher visual demands.

OBJETIVOS: avaliar peso, altura, índice de massa corporal (IMC) e prevalência de sobrepeso e obesidade de crianças e adolescentes de Presidente Prudente, São Paulo, Brasil. MÉTODOS: foram avaliados 1327 jovens (692 masculino e 635 feminino) com idade de 7 a 19 anos. Os dados foram coletados com o mesmo equipamento e seguindo procedimento padrão descrito na literatura. O teste t de Student para variáveis independentes foi utilizado para as comparações entre sexo (p<0,05), e foram calculados os percentis para cada idade. Utilizou-se o programa SPSS, versão-10.0. A plotagem das curvas foi realizada no programa Minitab, versão-14.0. Os percentis 85 e 95 serviram para classificação de sobrepeso e de obesidade e foram analisados em relação aos dois estudos mais aceitos internacionalmente. RESULTADOS o peso e a altura estão acima dos valores encontrados em outras regiões brasileiras e semelhantes a dos países desenvolvidos. O IMC revelou alta prevalência de sobrepeso e obesidade, principalmente no sexo masculino, entre 7 e 10 anos. Esta prevalência foi menor no grupo feminino, especialmente entre as adolescentes. CONCLUSÕES: a amostra apresenta padrão de crescimento acima de outras regiões brasileiras e comparáveis a países desenvolvidos, entretanto o IMC indica alta prevalência de sobrepeso e obesidade.

Bucioli, SA, de Abreu, LC, Valenti, VE, and Vannucchi, H. Carnitine supplementation effects on nonenzymatic antioxidants in young rats submitted to exhaustive exercise stress. J Strength Cond Res 26(6): 1695-1700, 2012-Previous studies have demonstrated that exercise stress increases oxidative stress in rats. However, antioxidant supplement therapy effects on reactive oxygen substances are conflicting. We evaluated the effects of carnitine on renal nonenzymatic antioxidants in young rats submitted to exhaustive exercise stress. Wistar rats were divided into 3 groups: (a) control group (not submitted to exercise stress), (b) exercise stress group, and (c) exercise stress and carnitine group. The rats from group 3 were treated with gavage administration of 1 ml of carnitine (5 mg.kg(-1)) for 7 consecutive days. The animals from groups 2 and 3 were submitted to a bout of swimming exhaustive exercise stress. Kidney samples were analyzed for reactive substances to thiobarbituric acid by malondialdehyde (MDA), reduced glutathione (GSH), and vitamin-E levels. Carnitine treatment attenuated MDA increase caused by exercise stress (1:0.16 +/- 0.02 vs. 2:0.34 +/- 0.07 vs. 3:0.1 +/- 0.01 mmmol per milligram of protein; p < 0.0001). It also increased the renal levels of GSH (1:23 +/- 4 vs. 2:23 +/- 2 vs. 3:58 +/- 9 mu mol per gram of protein; p, 0.0001); however, it did not change renal vitamin E (1:24 +/- 5 vs. 2:27 +/- 1 vs. 3:28 +/- 5 mu M per gram of tissue; p < 0.001). In conclusion, carnitine improved oxidative stress and partially improved the nonenzymatic antioxidant activity in young rats submitted to exhaustive exercise stress.

OBJETIVOS: descrever os achados do exame de potencial evocado auditivo de tronco encefálico (PEATE) de crianças de um programa de triagem auditiva neonatal e analisar a diferença de gênero e a interferência da idade nas medidas da latência das ondas do PEATE. MÉTODOS: para tal foram avaliadas 41 crianças com idade entre um a nove meses, referenciadas de um Programa de Triagem Municipal ao Centro de Estudos de Educação e Saúde (CEES) na cidade de Marília, SP no ano de 2010. RESULTADOS: foi observado resultado normal em 31 (75,6%) e alterado em 10 (24,4%) pacientes. Nesses últimos foram observadas alterações principalmente do tipo condutiva unilateral e bilateral. Observou-se também que a medida que a idade aumenta a latência das ondas diminui numa correlação inversa. CONCLUSÕES: o diagnóstico das crianças deste Programa de Triagem Auditiva Neonatal foi precoce. Os resultados do PEATE poderão servir de referência para outros estudos deste âmbito. O PEATE nesta população permite um melhor direcionamento da conduta e intervenção e aconselhamento específico aos familiares.

This article analyzes the creation and development of the São Paulo police force during the early years of the republican regime. In a period of political change and turbulence, institutional upheaval (uprising of the Navy and federalist revolution), and social pressure, São Paulo's police force played an important role. As the state sought to organize the public sphere, the police force became a tool in the new government's hands. A more martial set of demands mobilized a large portion of the troops on behalf of the federal government against the Custodio de Mello uprising, and sought to defend São Paulo's borders. Despite official discourse that fomented a militarized response, São Paulo's police force found itself unable to dismiss old personnel and practices and dislodge entrenched interests.

This article examines the challenges involved in the process of police militarization and implementation of police discipline in the State of São Paulo during the First Brazilian Republic (1889 to 1930). The implementation of a militarized police model, initiated by the 1906 French Military Mission, was not fully able to deal with indiscipline issues among policemen. Beyond creating problems of its own, such as fostering a corporatist culture and strengthening rigid hierarchies, military discipline prevented police forces to address new issues that would affect its practices. Documents in the São Paulo State Public Archive provides a window to the daily violence, the personal compromises, the institutional conflicts and the political meddling that was part of police life in the State of São Paulo at the turn of the century.
