The niche breadth of the Portunidae and their overlap on the subtidal sediments of Fortaleza bay, Ubatuba (São Paulo) was analyzed. Samples were made monthly from November/1988 to October/1989, inseven areas of the bay using a shrimp fishery boat equipped with two otter-trawls. Each area was characterized based on environmental factors such as depth, temperature, salinity, dissolved oxygen, organic matter and granulometric composition of the sediment. The number of individuais of each species was registered to each area (resource). Levins's standardized measure (BA) and niche percentage were calculated. Five species of swimming crabs were recorded in this study: Callinectes ornatus Ordway, 1863, Arenaeus cribrarius (Lamarck, 1818), Portunus spinimanus Latreille, 1819, Callinectes danae Smith, 1869 and Portunus spinicarpus (Stimpson, 1871). The widest ecological niche occurred to C. ornatus, present in all sampled areas (generalist species). Such fact can be related to high sediment tolerance when it is compared to P. spinimanus (especialist species) which was limited to the areas with coarse granulometric fractions. Highest niche overlap was verified between C. danae and A. cribrarius may be due to greater salinity tolerance of these species. The low occurrence of P. spinicarpus and its reduced niche size in Fortaleza Bay are due to association of this species to cold water currents (ACAS) more evidente in smaler depths during summer months. One future evaluation of the portunid diet can be useful to complement informations about this important aspect of the marine ecology.

Emerita brasiliensis Schmitt, 1935 is a common mole crab called tatuíra in Brazil, with distribution from Espírito-Santo State (Brazil) to Buenos Aires Province (Argentina). Specimens were collected bimonthly from May/1992 through March/1993 with 4mm siffers mesh, in the intertidal region at Vermelha do Norte Beach, Ubatuba, São Paulo, Brazil. The animals were sexed and measured with a precision caliper of 0.1 mm (Cl = carapace length). Males presented cl amplitude from 3.4-17.3mm (13.2±2.1mm), and females from 13.8-26.3mm (20.5±1.8mm), showing a well-defined sexual dimorfism for this variable. The population presented a smaller incidence of males in relation to females (0.54:1.00), however in May/1992 an inverse pattern occurred (1.84:1.00). Ovigerous females were present in all samples with exception of May and September/1992 with greater frequencies in July/1992 and January/1993. It is probable that female maturity occurs is reached with 17mm CL, the smallest size in wich ovigerous females were found.

Blood and bone marrow samples were taken from 112 Didelphis spp., collected between March 2005 and February 2006, from urban and peri-urban areas of Bauru, São Paulo State, Brazil, to evaluate the hypothesis that these animals might constitute a reservoir of Leishmania spp. Anti-Leishman ia ssp. antibodies were screened in the serum samples using an enzyme-linked immuno-sorbent assay (ELISA) and the polymerase chain reaction (PCR). PCR was performed on fragments of DNA samples from Leishmania spp. using primers 13A and 13B, and showed a positive outcome in 91.6% of the 112 samples tested. of the 107 samples analyzed by ELISA, 71 % were positive. Evidence of epidemiological risk factors such as a circulating parasite and freely moving vectors suggests that Didelphis spp. may participate in the transmission cycle of Leishmania spp. in Bauru.

The variation of soil textural characteristics is a function of the relief and parent materials. The objective of this work was to study soil texture spatial variability from different parent material in Pereira Barreto, SP. An area of 530.67 hectares was mapped through the use of Global Positioning System receivers and obtaining of Digital Elevation Models. A set of 201 soil samples was collected from every seven hectares, at three depths: 0 - 0.25 m; 0.25 - 0.50 m; and 0.80 - 1.00 m. The amounts of sand, silt and clay were obtained by the pipette method and analyzed by both descriptive statistics and geostatistics. Soil textures varied as a function of parent materials and topography.

O cancro cítrico, causado pela bactéria Xanthomonas axonopodis pv. citri Valterin et alii 1995, é uma doença conhecida mundialmente e sempre constituiu séria ameaça para a citricultura brasileira. O objetivo do presente trabalho foi analisar as condições climáticas do Estado de São Paulo e desenvolver mapas de zonas de maior risco de epidemias de cancro cítrico. Foram utilizados dados meteorológicos referentes aos anos de 2002 a 2005, os quais foram baseados no modelo de previsão desenvolvido por Campbell & Madden (4) e Hau & Kranz (10). A freqüência dos dados foi horária e quando alguma estação apresentava falha, esses eram extrapolados da estação mais próxima. Foram contabilizados os índices de favorabilidade e posteriormente calculadas as porcentagens de dias favoráveis à ocorrência da doença no período de um ano. A partir destas informações, foram gerados os mapas temáticos do Estado de São Paulo, com a distribuição espacial da porcentagem de dias favoráveis à ocorrência de cancro cítrico. A região Noroeste do Estado foi a que apresentou a maior porcentagem de dias favoráveis à ocorrência de cancro cítrico.

This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position´s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de São Paulo-Metrô (line yellow 4). And the flying disaster involving the airbus of Transportes Aéreos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the São Paulo´s government, in the person of the politician actor José Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis Inácio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy

Recentemente a Secretaria de Agricultura e Abastecimento do estado de São Paulo abrandou os critérios relacionados à erradicação do cancro cítrico. em abril de 2009 mais de 99,8% dos talhões comerciais de laranjeiras doces estavam livres da doença em São Paulo. Abrandar a metodologia de erradicação significa comprometer esse elevado nível de sanidade dos pomares e a competitividade da citricultura, com reflexos negativos financeiros e ambientais. Diante desses fatos sugere-se: a) que a erradicação da doença volte a ser feita como anteriormente utilizada; ou b) a adoção de uma nova metodologia de erradicação, mais efetiva na supressão da doença, quando em novos levantamentos amostrais de cancro cítrico em São Paulo forem encontradas incidências de talhões comerciais com a doença superiores a 0,36%. Essa incidência foi calculada comparando-se pelo teste de Duncan (P<0,05) os levantamentos amostrais de cancro cítrico realizados de 1999 a 2009. A diferença mínima significativa encontrada foi de 0,28. A menor incidência do cancro cítrico em São Paulo foi de 0,08%, observada em 2001. Dessa forma, como alternativa, propõe-se a adoção de uma metodologia mais drástica de erradicação do cancro cítrico quando em um novo levantamento amostral for detectado mais que 0,36% de talhões comerciais com cancro cítrico.

OBJETIVOS: Determinar a frequência de retinopatia da prematuridade no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto (HCFMRP-USP) e verificar a associação da retinopatia da prematuridade com fatores de risco conhecidos. MÉTODOS: Foi realizada análise prospectiva de 70 pacientes, nascidos no HCFMRP-USP, com peso inferior a 1.500 gramas, no período de um ano. Os pacientes foram divididos em dois grupos (Retinopatia da prematuridade e Normal) para realização de análise estatística com relação a fatores de risco conhecidos. Adotou-se nível de significância de 5%. RESULTADOS: A frequência de retinopatia da prematuridade foi de 35,71% entre os pré-termos estudados. Os fatores pesquisados que apresentaram relação de risco para o desenvolvimento da doença foram: peso (p=0,001), idade gestacional (p=0,001), escore SNAPPE II (p=0,008), uso de oxigenoterapia por intubação (p=0,019) e por pressão positiva de vias aéreas (p=0,0017), múltiplas transfusões sanguíneas (p=0,01) e uso de diuréticos (p=0,01). CONCLUSÃO: A frequência de retinopatia da prematuridade foi de 35,71% entre os prétermos nascidos com menos de 1.500 g. Vários fatores de risco foram identificados nos recém-nascidos do HCFMRP-USP, sendo constatado que crianças mais pré-termos apresentam formas mais graves de retinopatia da prematuridade.

This study aims, to characterize the diversity of cephalopods by analyzing the stomach contents of fishes caught in the islands of St. Peter and St. Paul (ASPSP) and Fernando de Noronha (AFN). Also, verify the participation of cephalopods in the diet of their main predators. A total of 723 stomachs were collected, from 8 species of fish, caught by the fishery, 471 stomachs were from ASPSP and 252 were from the AFN. It was recorded the occurrence of food items (fish, cephalopods and crustaceans) and the cephalopods were identified to the lowest taxa possible, according to specialized literature. The Ommastrephidae family represented 84.46% of occurrence in the ASPSP and 63.48% in the AFN, confirming the importance of this family in the area studied and also in the diet of their predators. Among the species with greatest occurrence Ornitoteuthis antillarum was the most representative in both regions. This species had an average mantle length of 54.25 mm, thus demonstrating that the majority of this population is in the juvenile stage of development. The smallest species found was Argonauta nodosa with a mantle length of 4.06 mm and the largest was Ommastrephes bartrami, with 223.33 mm. In the AFN, the species richness (d) was 2.318, the diversity index (H ') was 1.454 and the measure of evenness (J) was 0.585. In the ASPSP, the species richness (d) was 2.66, the Shannon diversity index (H ') was 1.013 and the measure of evenness (J) was 0.373. AFN has a greater cephalopod diversity than ASPSP, confirming the pattern suggested by the Theory of Island Biogeography. Among the occurrence of prey items for all predators, the cephalopods are secondary preys. The most important cephalopod species in the diet of Thunnus albacares and Acantocybium solandri was Ornithoteuthis antillarum. These predators have different niche width the diet of Thunnus albacares is more specialized, but they have an overlap of 84.684% in the trophic niche, suggesting that in the ASPSP these two species may use similar niches

Este trabalho teve como objetivo avaliar as características morfométricas das microbacias (2ª, 3ª, 4ª e 5ª ordens de magnitude) da bacia hidrográfica do córrego Rico, sub-bacia do Rio Mogi-Guaçu, localizada na região administrativa de Ribeirão Preto, Estado de São Paulo, Brasil. Para tanto, foram determinados os parâmetros físicos e a configuração topográfica natural do sistema de drenagem. Os procedimentos para a obtenção dos dados foram fundamentados em técnicas de sensoriamento remoto e geoprocessamento. A partir da vetorização das cartas topográficas correspondentes à área de estudo, realizou-se a análise morfométrica quanto às características dimensionais, do padrão de drenagem e do relevo no sistema de informação geográfica ArcView. A microbacia é considerada de sexta ordem de magnitude, com área estimada de 542 km², com 85 microbacias de segunda ordem, 22 de terceira, sete de quarta ordem e duas de quinta. Utilizando o critério geométrico, na disposição fluvial das sub-bacias de cabeceiras observou-se a predominância dos modelos dendríticos e subdendríticos, enquanto a jusante predominava o modelo subparalelo, respectivamente, nas áreas de ocorrências dos arenitos Bauru e rochas efusivas básicas.
