The expansion of sugarcane monoculture in Brazil in the last decades has pointed out to the necessity of considering the question of sugarcane cutters occupational health. In this work we present a cross-sectional study aiming to examine the occupational posture of a group of sugarcane cutters, which work in a cane field located in the region of Pontal do Paranapanema-SP, Brazil. The study was made using the Ergonomic Analysis of Work - EAW methodology and the postural analysis method by Win-OWAS. Through the obtained records of postures, it was observed that during a workday the sugarcane cutters remain standing erect on two legs or in one leg 66% of the time and that their trunk remain tilted and in rotation, according to 63% of the positions categorized. It was also observed that the sugarcane cutter trunk performs repetitive and boundless movements during his routine of work, which can expose this individual to additional wear of their musculoskeletal functions. The activities in which the individual engages have favorable or adverse influence on his posture. The repetitive movements involved in specialized occupations are equivalent to repeated exercises, thus may be responsible for the excessive development of certain muscle groups. The study suggests that the postures adopted by sugarcane cutters can overload their musculoskeletal system and predispose the cutters to work-related musculoskeletal diseases.

Estudou-se o comportamento biológico e histopatológico de uma cepa genuínamente mariliense de Trypanosoma cruzi, isolada em 1997 através de xenodiagnóstico artificial. Vinte e cinco camundongos swiss foram infectados intraperitonealmente, sendo 11 utilizados para a realização da curva parasitêmica e observação da morfologia dos tripomastigotas e 14 foram sacrificados após o 17, 23, 30, 60 e 180 dias pós-infecção e coletados coração, esôfago, fígado, cólon, e músculo esquelético (fragmento da coxa direita) para análise histopatológica. Cultura em meio LIT foi realizada para análise de DNA. Os resultados mostraram predomínio de formas largas, baixa parasitemia com picos médios de 860 tripomastigotas/5mil de sangue ao redor do 20º dia de infecção. Nenhum camundongo morreu na fase aguda da infecção. Exame histopatológico mostrou poucos ninhos de amastigotas em coração, raros em músculo esquelético e cólon com discreto processo inflamatório. Comparada com a cepa Y, que foi isolada de uma paciente da mesma região, notamos diferentes características biológicas e comportamentais, porém a análise de DNA as coloca no mesmo grupo, demonstrando a proximidade dessas cepas.

Avaliaram-se o crescimento vegetativo e a produção de cultivares novas e tradicionais de abacaxi na região de Bauru. As cultivares estudadas foram: 'Smooth Cayenne', 'Jupi', 'Imperial', 'Gold' e 'Gomo de Mel'. As mudas foram obtidas por cultura de tecidos pela empresa BIONOVA a partir de plantas-matrizes cedidas pela Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Mandioca e Fruticultura Tropical e por produtores comerciais e passaram por um período de 100 dias de aclimatação em telado acondicionadas em tubetes. O plantio no campo foi realizado em canteiros revestidos com 'mulching' plástico preto em janeiro de 2007. O delineamento foi em blocos casualizados, com quatro repetições. Cada parcela apresentou 32 plantas, e o sistema de plantio foi em linhas duplas, no espaçamento 0,30 x 0,50 x 1,0 m. A avaliação dos tratamentos foi baseada na determinação do nível de crescimento vegetativo (massa e comprimento da folha 'D' e diâmetro do caule) e nas características físicas dos frutos. Os resultados obtidos foram submetidos à análise de variância e ao teste de Tukey, a 5% de probabilidade. Nas condições ambientais da região de Bauru (SP), e considerando o uso de mudas obtidas por cultura de tecidos, os resultados deste trabalho indicaram a superioridade das cultivares 'Gold', 'Smooth Cayenne' e 'Jupi' em relação a 'Imperial' e 'Gomo de Mel', com crescimento vegetativo maior e produção de frutos mais pesados.

Silicified stromatolites have been described in the Permian Teresina Formation, Passa Dois Group, of the Parana Basin. These stromatolites occur as blocks in the Fazenda Monte Alegre area at the headwaters of the creek known as Corrego Catanduva in the municipality of Angatuba. These blocks originate from the Serra de Angatuba region and were recognized in a road that was cut in the midst of sandstones and siltites. The stromatolites are isolated bioherms that are domed to subspherical with a flat base in profile and a rounded to lenticular shape in plan view. The stromatolites exhibit a reddish coloration and are composed of microcrystalline quartz. Lamination is continuous, non-columnar, and anastomosed, showing parallel to divergent growth; however, divergent columns also occur, especially at the tops of the bioherms. The lamination is fine and well preserved, with alternating light and dark laminas. Microfossils of filamentous cyanobacteria are preserved and were related to the genera Microcoleus and Rivularia. Silicified bivalves occur in association with the stromatolites and are preserved in the form of coquina beds and rare isolated specimens within the bioherms. The described specimens belong to the Pinzonella illusa biozone, with representatives of the species Pinzonella illusa, Angatubia cowperesioides, and Houldausiella elongata. The formation environment of these stromatolites is associated with tidal plains of shallow, brackish, relatively calm, warm waters of good luminosity with the presence of weak currents. There was likely a low level of predation, and the environment may have been hypersaline. The coquina beds associated with the stromatolites indicate a probable proximal tempestite, i.e., they were formed near the coastline. The stromatolites were originally composed of carbonates, although these were replaced by silica during early diagenesis.

The presence of residues of the major groups of pesticides (organohalogen, organophosphorous, pyrethroids and organonitrogen) in representative samples of honey produced in Bauru (state of São Paulo, Brazil) was investigated from 1999 through2004. A multiresidue method was applied to honey samples to determine 48 pesticides with recoveries ranging from 76 to 95%. The limits of detection found were lower than 10 µg/kg for GC-MS-SIM. The results indicated that most pesticides found in the samples belonged to the organohalogen and organonitrogen groups. Residues of malathion were detected in almost all of the samples in high concentration.

The aim of this study was to analyze the cost of production and economic viability of production of Lambari in Monte Castelo/SP, with the primary market for the live-bait for sport fishing of carnivorous fish. To calculate the operating cost structure was used the model proposed by the Instituto de Economia Agricola from São Paulo/Brazil. In analyzing the economic viability of investment, we determined the Internal Rate of Return (IRR) and Pay Back Period. It was noted that the inputs represented approximately 74.0% of the EOC (Effective Operating Cost). In the rentability analysis (short term), there was an operating profit of R$ 3,133.45 for a cycle, with a profitability of 18.65% for four months of production, a cost price of R$ 13.02 kg(-1). For viability of the activity (long term), the results were attractive to recovery capital from the 3(rd) year (Pay Back), with an IRR of 25.68% and 89.0% return on the producer in 5 years (BCR - benefit cost ratio). The study of costs and economic viability analysis reinforce the importance of rational management in the productive system and the importance of planning and managing the profitability of the activity.

The taxonomy of the N(2)-fixing bacteria belonging to the genus Bradyrhizobium is still poorly refined, mainly due to conflicting results obtained by the analysis of the phenotypic and genotypic properties. This paper presents an application of a method aiming at the identification of possible new clusters within a Brazilian collection of 119 Bradryrhizobium strains showing phenotypic characteristics of B. japonicum and B. elkanii. The stability was studied as a function of the number of restriction enzymes used in the RFLP-PCR analysis of three ribosomal regions with three restriction enzymes per region. The method proposed here uses Clustering algorithms with distances calculated by average-linkage clustering. Introducing perturbations using sub-sampling techniques makes the stability analysis. The method showed efficacy in the grouping of the species B. japonicum and B. elkanii. Furthermore, two new clusters were clearly defined, indicating possible new species, and sub-clusters within each detected cluster. (C) 2008 Elsevier B.V. All rights reserved.
