1. CARTOGRAFIA REGIONAL DA LEPTOSPIROSE: DINÂMICA ESPAÇO-TEMPORAL DA PATOLOGIA NA 4 COORDENADORIA REGIONAL DE SAÚDE, RS. / REGIONAL MAPPING OF THE LEPTOSPIROSIS: SPATIOTEMPORAL DYNAMICS OF PATHOLOGY AT THE 4TH REGIONAL HEALTH DISTRICT, RS.
Leptospirosis is a ubiquitous disease, waterborne, with several animal reservoirs (wild and domestic) and urban and rural transmission, receiving climatic/socioeconomic influences. Its manifestations vary from asymptomatic and light tables to hemorrhagic fevers. This study aimed to evaluate the cases reported in SINAN of the 4CRS, RS, from 1999 to 2006, perf

2. Levantamento ambiental e pesqueiro dos rios Jaboatão e Pirapama no Estado de Pernambuco, Brasil
The increasing human populations that live on, work with and use resources of coastal areas place pressure on these resources, which, together with pressure from natural sources, must be monitored and understood in order to ensure the preservation of the environment and maintenance of quality of life. The rivers that empty along the coast of the state of Per

3. AvaliaÃÃo do processo evolutivo e da dinÃmica erosiva: um estudo de caso no municÃpio de Ipameri-GO
The municipal district of Ipameri has his economy based in agricultural activities that it unchained a series of erosive processes. This study had as objective a bibliographical revision about the fundamental aspects of the erosive process and the factors that condition his development. For demonstration of her evolution monitoring techniques were used, with

4. Rainfall retention in straw, plant and soil in corn and drybeans / Retenção de água da chuva na palha, solo e dossel vegetativo de milho e feijão
The water is the most important factor and, at the same time, the more limitant than the plant needs for its development. Short periods of hidric stress can reduce crop productivity. In this way, the importance of knowing the rainfall amount that is retained in plant, straw and soil is fundamental to calculating the exact amount of water requested by the pla

5. CHARACTERIZATION OF ENVIRONMENTAL CHANGES BY USE OF NATURAL RESOURCES FOR WORKERS IN RURAL HIGH COURSE PERICUMÃ RIVER / CARACTERIZAÇÃO DAS ALTERAÇÕES AMBIENTAIS SEGUNDO O USO DOS RECURSOS NATURAIS POR TRABALHADORES RURAIS NO ALTO CURSO DO RIO PERICUMÃ.
The characterization of the environment changes from the development of activities is approached in this study caused by human activities in their different ways of interaction society-nature, in the area of the high course of river Pericumã, one of the main basins of the area called Baixada Maranhense. It was considered that the population that use natural

6. A planície aluvial do médio rio araguaia: processos geomorfológicos e suas implicações ambientais / The alluvial plain of the middle Araguaia River: geomorphological processes and their environmental implications
The Araguaia River is the most important fluvial system of South America. With an area of 380.000Km, its includes two phytogeography regions that have a good part of planet biodiversity: Cerrado, in the south, and Amazonia Forest, in the north of Brazil. The high level of Cerrado ecosystem destruction and changes in the land using, after 1965, promoted an in

7. Efeitos da velocidade de rebaixamento do nível freático na produtividade da soja (Glycine max (L.) Merrill) e da ervilha (Pisum sativum L.). / Effects of the drawdown velocity of the water table in the crop yield of soybean (glycime max l. merrill) and of pea (pisum sativum l.).
No Brasil, os solos hidromórficos são basicamente utilizados no cultivo de arroz, principalmente na região Sul do Brasil. O plantio de outras culturas em substituição ao arroz, pode ser uma alternativa viável para a melhor exploração destes solos durante o inverno e no pousio da área. O presente trabalho foi realizado em casa de vegetação do Depar

8. In situ bacterial selenate reduction in the agricultural drainage systems of western Nevada.
Dissimilatory in situ selenate reduction to elemental selenium in sediments from irrigated agricultural drainage regions of western Nevada was measured at ambient Se oxyanion concentrations. Selenate reduction was rapid, with turnover rate constants ranging from 0.04 to 1.8 h-1 at total Se concentrations in pore water of 13 to 455 nM. Estimates of removal ra
