A memória dos carnavais Afro-Paulistanos na cidade de São Paulo nas décadas de 20 e 30 do século XX

Current analysis deals with memoirs of Carnivals celebrated by Negroes in the city of São Paulo during the 1920s and 1930s. The narrative tries to investigate the trajectory of the Afro-Brazilian group and the spaces used to express its performances during the festivities dedicated to Momo throughout the city of São Paulo, which was still characterized by wealthy people that controlled its several sections. Several discussions are endeavored to perceive the spaces fabricated by the group and its strategy to get together and celebrate Carnival (officially or non-officially). The form and meanings of playful art represented by such festivities are also highlighted.

Isolation of brucella spp from milk of brucellosis positive cows in São Paulo and Minas Gerais states

A brucelose é uma zoonose crônica de importância para a Saúde Pública. Considerando o pequeno número de dados brasileiros sobre a sua presença em leite cru e derivados não-pasteurizados, estudamos a presença de brucelas em leite de animais sorologicamente positivos. A soroaglutinação rápida (SAR), a soroaglutinação lenta (SAL) e a soroaglutinação lenta com tratamento do soro com 2-mercaptoetanol foram utilizados para identificar os animais positivos nas propriedades estudadas. Amostras diárias de 300 ml de leite foram colhidas por três dias de todos os quartos mamários produtivos (75 ml/teto). As amostras eram misturadas e centrifugadas. Parte do sedimento e do sobrenadante foi inoculada em meios de Farrel e Brodie-Sinton (BS) suplementados com agentes antimicrobianos. As placas e tubos foram cultivados por sete dias a 37ºC, em microaerofilia. As colônias suspeitas no meio BS foram imediatamente repicadas para ágar-Brucella, e cultivadas sob a mesma condição. Os microrganismos isolados foram submetidos a procedimentos de identificação, incluindo a coloração de Gram, requerimento de CO2, produção de H2S, atividade da urease e crescimento na presença de tionina e fucsina. Das 49 amostras examinadas, isolou-se Brucella abortus de 15 (30,61%). Os biótipos isolados foram: biótipo 1 em uma amostra (2,04%), biótipo 2 em oito (16,32%) e biótipo 3 em seis amostras (12,25%)

Non-stationary frequency analysis of extreme daily rainfall in São Paulo, Brazil

This work is an assessment of frequency of extreme values (EVs) of daily rainfall in the city of São Paulo. Brazil, over the period 1933-2005, based on the peaks-over-threshold (POT) and Generalized Pareto Distribution (GPD) approach. Usually. a GPD model is fitted to a sample of POT Values Selected With a constant threshold. However. in this work we use time-dependent thresholds, composed of relatively large p quantities (for example p of 0.97) of daily rainfall amounts computed from all available data. Samples of POT values were extracted with several Values of p. Four different GPD models (GPD-1, GPD-2, GPD-3. and GDP-4) were fitted to each one of these samples by the maximum likelihood (ML) method. The shape parameter was assumed constant for the four models, but time-varying covariates were incorporated into scale parameter of GPD-2. GPD-3, and GPD-4, describing annual cycle in GPD-2. linear trend in GPD-3, and both annual cycle and linear trend in GPD-4. The GPD-1 with constant scale and shape parameters is the simplest model. For identification of the best model among the four models WC used rescaled Akaike Information Criterion (AIC) with second-order bias correction. This criterion isolates GPD-3 as the best model, i.e. the one with positive linear trend in the scale parameter. The slope of this trend is significant compared to the null hypothesis of no trend, for about 98% confidence level. The non-parametric Mann-Kendall test also showed presence of positive trend in the annual frequency of excess over high thresholds. with p-value being virtually zero. Therefore. there is strong evidence that high quantiles of daily rainfall in the city of São Paulo have been increasing in magnitude and frequency over time. For example. 0.99 quantiles of daily rainfall amount have increased by about 40 mm between 1933 and 2005. Copyright (C) 2008 Royal Meteorological Society

Genetic aspects of productive and reproductive traits in a Murrah buffalo herd in São Paulo, Brazil

This study investigated genetic trends of some productive and reproductive traits in a herd of Murrah buffalo raised in São Paulo, Brazil. Variance components for milk production (Mr), length of lactation (LL), calving interval (CI) and age of first calving (AFC) were estimated by che restricted maximum likelihood method, using an animal model. Estimated heritability values were 0.38; 0.01; 0.10 and 0.20 for MP, LL, CI and AFC, respectively. Estimated repeatability values were 0.50, 0.13 and 0.20 for MP, LL and CI, respectively. Means of predicted breeding values for cows, dams and sires according to calving year and the genetic correlations were presented.

Contribution to the study of diarrhea etiology in neonate dairy calves in São Paulo state, Brazil

Amostras fecais de 203 bezerros com diarréia, idade inferior a 30 dias, de ambos os sexos e de diferentes propriedades do Estado de São Paulo foram examinadas num período de dois anos. Cultivos para pesquisa bacteriana foram feitos em agar acrescido de 10% de sangue bovino e agar Levine. As placas foram incubadas por até 96 horas, em condições aeróbias, a 37°C, com observação dos aspectos de colônia e estudos morfológicos, bioquímicos e realização de outros testes, quando pertinentes. O teste de ELISA foi aplicado para pesquisa de Rotavirus. Cryptosporidium spp. também foi pesquisado e identificado. Resultados revelaram envolvimento de vários patógenos de forma isolada, assim como associados. Rotavirus foi encontrado em 51 (25,1%) das amostras, sendo em 58,8% só, em 41.7% associado a outros microrganismos. Cryptosporydium spp foi isolado em 43 (21.3%) das amostras, sendo só em 65,1% delas e associado a outros enteropatógenos em 34,9%. No exame parasitológico foram encontrados ovos de estrongilídeos em 5 (2,5%) das amostras, não excedendo mais de dois ovos por campo examinado. Ao exame microbiológico, um ou mais microrganismos foram isolados. Escherichia coli foi encontrada em 100% das amostras. As pesquisas de toxina termoestável e do antígeno de aderência K99 realizada nas 73 amostras de E.coli foram negativas, e o grupo sorológico das mesmas foi determinado, sendo 34,2%, 17,8% e 47,9% das amostras pertencentes aos sorogrupos O8, O11 e O101, respectivamente. Salmonella Dublin e Salmonella typhimurium foram isoladas em 5,4% e 6,1% das amostras examinadas, respectivamente.

Spider assemblages in widely-separated patches of cerrado in São Paulo State, Brazil.

Brazilian cerrado is a biologically-rich, poorly understood, yet rapidly disappearing habitat. Composition of the spider assemblages from areas of cerrado from three separate sites in the State of São Paulo, Brazil were sampled by beating the canopies and adjacent shrubs of three Myrcia (Myrtaceae; "myrtle") tree species. These produced a total of 859 spiders 'belonging to 21 families and 75 species. The most undisturbed and densest cerrado habitat had the largest number and greatest diversity of spider species, encompassing stalkers, ambushers, space web-weavers, and foliage runners. The other two areas were dominated by foliage runners. Spider distribution in this natural and complex habitat was evaluated by classifying the samples into 12 habitat/microhabitat groups according to local of the patch, tree species, and microhabitat (target tree or adjacent shrub). Correspondence analysis was used for ordination of species and groups based on their abundance. Environmental factors such as patches type (p=0.027) and plant species (p=0.046) had significant effects in explaining the ordination. Canonical correspondence analysis was applied for relating the patterns in species richness and/or abundance to the significant environmental factors. A comparison of the results showed that the family composition among the patches is rather similar, and there is a tendency of spiders species overlap an interregional level (patches effect, p=0.027). However, the most similar spider assemblages living on woody vegetation occurred in Myrcia venulosa and Myrcia guianensis at São Carlos and Pirassununga, demonstrating an interregional similarity (plant species effect, p=0.046) that indicates an association between spiders and particular vegetation.

Identification of races of Bremia lactucae in São Paulo, Brazil

Lettuce, Lactuca sativa, is the most important leafy vegetable in the diet of the Brazilian people. However, the lettuce crop is susceptible to downy mildew disease which is caused by the fungus Bremia lactucae. Downy mildew is most troublesome during winter conditions in regions with mild temperatures. This coincides with the time for growing large quantities of lettuce. The high cost of cultivation and the infection of downy mildew in the winter, just when market prices are low, provides an economic challenge for Brazilian growers. The objective of this study was to identify the races of Bremia lactucae that occur in the growing regions of São Paulo during 2004. The study was conducted in the Laboratory of Vegetable Crop Genetics in the Department of Crop Production of the Faculty of Agricultural and Veterinary Sciences - UNESP, Jaboticabal Campus. In the present study, 92 isolates of B. lactucae were identified from São Paulo. The isolates were shown to display mainly a Sextet code 63/63/51/00 behavior, characterizing the race with regard to coverage and economic importance. The genes that confer resistance accounting for this behavior are DM 17, DM 18 and DM 38. Their use is recommended as sources of resistance to downy mildew in lettuce breeding programs.
