The objective of this study is verify the occurrence of bullying in soccer and if this phenomenon can be considered a possible cause of the abandonment of this sport. The sample consisted of 143 male athletes, aged between 15 and 18 years old, all of whom competed in the Copa São Paulo de Futebol Júnior in 2011. The results show that most athletes have practiced, suffered and observed bullying in soccer, but the minority has fear of being assaulted on the team and few thought to stop playing because of this social phenomenon. It is suggested that more studies be conducted in this area and that the sport psychologist and coach provide to the team a better living and training structure, and the athletes should be united, avoid jokes that exceeding the limits offending another member of the group and make everyone feel comfortable in that place, not influencing the individual or collective performance

The decreasing availability of drinking water is a problem that has existed for a long time and continues to be aggravated, especially by the increase in population and pollution of water resources. Due to the need to find alternatives in order to ensure water supplies in sufficient quantity and quality for consumption by populations, rainwater collection arises as an alternative. The present study was developed in Ipeúna-SP, consisting of an experimental system of collection and storage of rainwater on the roofs of buildings. Samples of the same precipitation, differentiated through the initial disposal and treatment of the collected water, were stored during a period of six months and monitored through physical, chemical and microbiological analyses. With the results, the qualitative characteristics of the stored precipitation were found, the main differences among the samples were identified and the needs of treatment were studied.

Aves podem ter sua distribuição e ocorrência associadas com a estratificação vegetal e a composição florística de cada ambiente. Diversos estudos mostraram que quanto mais estratificado um ambiente e mais diverso em composição florística, maior a densidade de aves ali existente. Espécies frugívoras que se alimentam no sub-bosque podem mostrar preferências por frutos mais vistosos, por serem mais fáceis de localizar em meio à vegetação florestal. Considerando isso, o presente estudo teve como objetivo verificar se existe diferença na composição e densidade de aves que se alimentam de frutos no sub-bosque de duas áreas de restinga (uma com maior estratificação vegetal que a outra), bem como testar se estas aves apresentam preferências por frutos vermelhos ou roxos. Para tanto, modelos de frutos foram confeccionados com massa de modelar e dispostos em uma área de restinga alta (vegetação atingindo até 20m) e outra de restinga baixa (vegetação até 10m). Para avaliar a preferência entre diferentes cores de frutos, os modelos foram dispostos em 2 indivíduos de Rubiaceae, cada qual contendo 5 frutos somente de uma cor, formando blocos pareados. Em cada área, 10 blocos foram dispostos. A quantidade de bicadas por cor por bloco em cada área foi contabilizada ao fim de quatro dias de exposição dos modelos. Um total de 5 horas de observações focais foi feito para verificar a composição das possíveis aves visitantes aos modelos. As diferentes formas de marcas deixadas pelas bicadas foram classificadas em cinco categorias. Não foram encontradas diferenças na quantidade de bicadas entre as diferentes cores para as duas áreas, nem preferências por cores, sem discriminar as áreas. Não foi avistada nenhuma ave bicando os modelos durante o período. Apesar de frutos roxos aparentarem menor conspicuidade em contraste com a vegetação do que frutos vermelhos...

The geophysical methods are used as tools that, together with other data, assist in target detail and sizing of ore bodies. This paper presents the results of the application of DC resistivity geophysical method on a manganese mineral occurrence located in Itapira, in the northern portion of São Paulo state, hosted predominantly in schists and quartzits of Itapira Group. The integration of geophysical data resulted in the elaboration of electrical resistivity models, where it was possible observe that the mineralized body, composed predominantly of manganese oxides and hydroxides, has a pattern of high resistivity (above 5000 Ω.m) both surface and subsurface. The contrast with the host rock is characterized mainly by different minerals assemblages and by the presence of local groundwater. The results accomplished in this paper reveal that the application of DC resistivity method is valid in primary evaluations of supergene deposits

Raias da espécie Narcine brasiliensis são frequentemente encontradas em regiões de substrato arenoso e lodoso localizadas entre o sudeste do Brasil e norte da Argentina, entretanto, há poucos estudos sobre seu ciclo de vida, assim como aspectos de sua distribuição e abundância. Verificar suas medidas corporais torna-se crucial para tais estudos, principalmente quando estes estão relacionados ao crescimento, maturação, comprimento máximo e estrutura populacional de elasmobrânquios. O presente estudo teve como objetivo analisar a ocorrência, a morfometria e o crescimento relativo da espécie no litoral do estado de São Paulo. Sendo assim, foram tomadas e avaliadas 46 medidas morfométricas corporais. Para verificar se havia diferenças significativas das proporções corpóreas entre machos e fêmeas, foi aplicado o teste “t de Student” e o teste de “Wilcoxon Rank”, conforme a distribuição da normalidade dos dados. Para avaliar a relação entre os caracteres morfométricos durante o crescimento dos indivíduos, foram ajustadas regressões lineares entre o logaritmo do comprimento total e o logaritmo de cada uma das variáveis, estimando-se o coeficiente alométrico (b); sendo b=1 (isometria), b>1 (alometria positiva) e b<1 (alometria negativa). Por último, foi verificado se havia diferença significativa do coeficiente alométrico (b) entre machos e fêmeas por meio de uma análise de covariância. A amostra analisada foi composta por 72 fêmeas de 237 a 470 mm e 33 machos de 236 a 380 mm. Os indivíduos foram capturados em substrato arenoso, sendo que não estiveram presentes indivíduos neonatos provavelmente pelo local de captura e seletividade da rede. Diferenças significativas foram encontradas na comparação das proporções corpóreas de machos e fêmeas, exceto para a região do espiráculo. As regressões lineares das variáveis logaritmizadas mostraram presença de isometria em 39,5%, alometria positiva em ...

The city of Guaratinguetá, SP, presents in its history, several instances of property damage and human losses, conditional on the event of flooding and mass movement of soil, resulting from the development of erosion processes. The extent and severity of these events that affect humans and their properties is the result of the illegal occupation of these areas as potential geohazard. Thus, it is of great importance to physical characterization and identification of such areas within the map of the same city as a way to minimize the effects and mitigate the consequences of these events. Thus, this graduate report presents a series of field campaigns, geotechnical laboratory testing, consultation with maps and satellite images, representative of the physical environment, and the city plan as a means conclusive for the delimitation of risk areas with potential for occurrence of erosion and / or flooding on the map representing the urban area of Guaratinguetá, SP. Also featured are the descriptions of the main characteristics of those areas identified as being at risk, along with proposals to avoid or minimize the impact of problems related to flooding and erosion processes on the local population

The Brazilian fauna has been constantly threatened by deforestation and forest fragmentation. As a result, many populations become isolated and small which negatively impacts their genetic diversity, putting them at a higher risk of extinction than large and stable populations. The aim of this work was to estimate the genetic diversity of white-lipped peccaries (Tayassu pecari) in the region of Taboco (Corguinho, MS), a fragmented area; and to compare these estimates with that obtained previously for two populations from Brazilian Pantanal, which is considered a relatively well-preserved biome and where the species is not threatened. A total of 18 blood and 72 hair samples of white-lipped peccaries had their DNA extracted and amplified for five polymorphic microsatellite loci. With the individuals identified, genetic diversity indicators (such as number of alleles, allelic richness, expected end and observed) and the inbreeding coefficient FIS were calculated. In addition, to verify if the population suffered a recent population bottleneck, we used the tests implemented in the program Bottleneck. The population of Taboco showed no evidence of recent population bottleneck (p > 0.05) or inbreeding (FIS = 0.008; p > 0.022). In addition, the levels of genetic diversity in this population (mean number of alleles = 2.60; mean allelic richness = 2.56 mean observed and expected heterozygosities = 0.45 and 0.47, respectively) were statistically similar to those found previously for the two populations from Pantanal (p > 0,05); although the region of Taboco is more impacted than the Pantanal. Even though we showed no evidence of loss of genetic diversity, it does not mean that the population is not suffering with fragmentation; but that there was not sufficient time to evidence the genetic changes. In addition, may be occurring gene flow with populations of nearby fragments, which is maintaining... (Complete abstract click electronic access below)

Air pollution is an environmental issue worldwide and frequently cause negative effects on population health and ecosystems on cities. The relationship between climate and atmospheric pollution can be used as a surrogate to the intensity of air pollution. The present and quantity of some gases can be used as indicators to air quality: particulate matter (PM), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and nitrogen dioxide (NO2). Among those gases, CO has its major source within the cities, where automobiles are the main emitter. But measure pollutant concentration are challenging, sometimes because the lack of good equipments due to high costs and of the large variability of models that varies in precision, way of measure and distribution of sellers. Modeling are useful when there are an intend to evaluate air pollution, its sources and evaluate scenarios. This work aims to use CAL3QHCR model developed by the U.S Environmental Protection Agency (EPA) to generate predictive surfaces of CO concentration distribution on a site within Campinas city, located in São Paulo state, Brazil. CAL3QHCR model use data urban automobile circulation to generate spatial results for CO distribution. We observed that the pollution concentration was lower on our modeling than the concentrations measured by Companhia Ambiental do Estado de São Paulo (CETESB), the main environmental company on the São Paulo state. Also the correlation between average estimates of our model and the measure by CETESB was weak, indicating that the model used on this study need to be or better parameterized, or the scale we measured of CO emissions need to be rescaled. Although the model failed to correlate to CETESB data, maybe one that explore the estimated emissions distributed within the sites to understand spatial distributions of CO on the regions. Also, the generated information can also be used to other studies, and come to be useful to explain heat island
