1. Managing agricultural phosphorus to minimize water quality impacts
ABSTRACT Eutrophication of surface waters remains a major use-impairment in many countries, which, in fresh waters, is accelerated by phosphorus (P) inputs from both point (e.g., municipal waste water treatment plants) and nonpoint sources (e.g., urban and agricultural runoff). As point sources tend to be easier to identify and control, greater attention has

2. Avaliação do desempenho de pavimentos permeáveis / Experimental analysis of permeable pavements
This study aimed to evaluate the experimental performance of three types of permeable pavements constructed in three different structural conditions in order to control runoff in urbanized areas of the city of Goiania, Goias, adapting to the legal requirements and using local manufactured materials. It was evaluated nine experimental plots of 3.2 m as the fo

4. Desempenho de plantas de cobertura no controle da erosão hídrica no Sul de Minas Gerais / Performance of cover crops to control erosion in the South of Minas Gerais
The erosion initiates with the impact of the raindrop on the soil surface, causing the transport of sediment, nutrients and organic matter. To reduce this erosion, the use of conservation practices, such as proper management and planting of cover crops that reduce these losses, is essential. The objective of this study was to evaluate the potential of plant

5. Influência do uso da terra na incidência de processos de dinâmica superficial na região de Marília (SP)
The study area comprises the western portion of the Marília Plateau, State of São Paulo, southeastern Brazil, whose geological substrate encompasses Cretaceous sedimentary rocks of the Bauru Group and local Cenozoic units like colluvium aprons, fluvial terrace deposits, in situ regoliths, and modern alluvial deposits. In a geomorphologic sense, the study a

6. Quantification of impervious surfaces in urban areas using remote sensing techniques / Quantificação das superfícies impermeáveis em áreas urbanas por meio de sensoriamento remoto
Impervious surface coverage growth has direct consequences in quantity and quality of stormwater runoff, such as floods and nonpoint source pollution. The quantification of basins imperviousness makes possible to use it as a water quality indicator for urban areas and as an important planning and managing instrument in the urban water resources management sy

7. A WATERSHED INFORMATION SYSTEM (WIS) FOR WATER QUALITY ANALYSES
Assessments of water quality in surface water bodies are increasingly incorporating both point and non-point pollutant sources. Water quality constituents are transported in the water as well as on the sediments. Predictions of constituent concentrations in the water and on the sediments require simulation models of water and sediment transport processes ove

8. Diagnostico de processos erosivos lineares associados a eventos pluviosos no municipio de Bauru, SP
In the municipal district of Bauru occur several gullies of great load, unchained by surface water runoff concentration, propitiated by the disordered occupation of urban and rural areas. Considering the gravity of those occurrences, so much in number as in load, the municipal district is one of the most critical in the State of São Paulo. This work has for

9. Regulation of insulin-like growth factor I gene expression in the human macrophage-like cell line U937.
Activated macrophages release tissue forms of insulin-like growth factor I (IGF-I), 20-25-kD products of the IGF-I gene, thus providing an extracellular growth and differentiation signal at sites of inflammation. To examine the control of IGF-I gene expression in mononuclear phagocytes, the human macrophage-like cell line U937 was evaluated at rest and after

10. Murine retroviruses control class I major histocompatibility antigen gene expression via a trans effect at the transcriptional level.
Moloney murine leukemia virus (M-MuLV) and Moloney murine sarcoma virus (M-MSV) exert a regulatory effect on the class I genes of the murine major histocompatibility complex (MHC). We have previously shown that M-MuLV infection of mouse fibroblasts results in a substantial increase in cell surface expression of H-2K, H-2D, and H-2L proteins, whereas M-MSV, u
