Uso de imagem CBERS no zoneamento geoambiental em bacia hidrográfica do estado da Paraíba, Brasil.

This work aims at generating georeferred maps of the main landscape elements from the geoenvironmental mapping of the Camará hydrographic basin. The map was generated from the interpretation and digital processing of CBERS images using the SPRING/INPE software with RGB composition of bands 2, 3 and 4, and data obtained from field sampling. The results indicate that the greatest part of the hydrographic basin is composed by Regosols (45%) and Acrisols (36%) associated with Leptosols, Fluvisols, Cambisols, and Luvisols. Capoeira brushwood ? which is mistaken for pasture by automatic classification due to the fact that it is an abandoned, recovering area historically used for agriculture and pasture ? covers an area of almost 38%, whereas 13% of the total area are explored for banana and citrus crops, especially in humid regions. Pangola grass (Digitaria decumbens Stent), guinea grass (Panicum maximum Jacq. var. gongyloides Doell), and napier grass (Pennisetum purpureum Schum.) dominate pasture areas, and take up 27% of the total area. The geoenvironmental unit that presented high environmental vulnerability was Encosta São Tomé, which comprises 3.5% of the basin, due to the fact that 90% of this area presents a strongly undulate to mountainous landscape, and 80% of its soil is shallow or very shallow, whereas low environmental vulnerability was detected in areas with associations of deeper soils, such as Regosols and Acrisols, which present plain to mildly undulate landscape, which occurred in 5% of the total area

GeoPAC: Sistema de Monitoramento de Obras do PAC.

O objetivo deste documento é descrever o sistema GeoPAC. São apresentados seu histórico de desenvolvimento, sua arquitetura de software, suas principais funcionalidades e alguns exemplos de análises de contexto territorial elaboradas pela Embrapa, a partir dos dados espaciais dos empreendimentos do PAC catalogados pelo sistema. O GeoPAC está disponível remotamente para o Ministério do Planejamento, Orçamento e Gestão (MPOG) e é fornece diversos parâmetros e indicadores utilizados no acompanhamento territorial dos empreendimentos do PAC.bitstream/item/98227/1/20140225-GeoPAC2.pd

Differentiating cave Aspidoras catfish from a karst area of Central Brazil, upper rio Tocantins basin (Siluriformes: Callichthyidae)

Two cave populations of Aspidoras albater catfish with reduced eyes and pigmentation were recently found near the city of Posse, São Domingos karst area, Goiás State, representing the first known case of a troglomorphic callichthyid catfish. Cave specimens are described and compared to epigean specimens of A. albater, but morphometric differences between the epigean and the cave populations are not adequate to delimit as distinct species.</jats:p

Deslocamento De Longa Distaˆncia Por Um Grande Morcego Frugı´voro, Artibeus Lituratus (olfers, 1818), No Sudeste Do Brasil (chiroptera, Phyllostomidae): Evideˆncia De Migrac¸a˜o De Morcegos Neotropicais?

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)In Brazil, bat migrations have been inferred based on seasonal variations in bat abundances observed for several species, probably as a result of variations in temperature and food availability. However, direct evidence of individual medium to long distance (4 10 km) movements, based on marked specimens, is restricted to large frugivorous bats, genus Artibeus (Phyllostomidae). We report the longest bat movement recorded in Brazil, along 113 km in a straight line, difference in altitude of 738 m, from a mixed Araucaria forest in Curitiba, PR, to the Atlantic Forest, Alto Ribeira, SP, by a female Artibeus lituratus (Olfers, 1818), over a period of 14 months. This data is consistent with the occurrence of migratory movements in Neotropical bats, such as the ecologically flexible Artibeus spp., over relatively large areas, probably with short stopover foraging intervals. Implications for the conservation of these bats are clear, as their home ranges may be much larger than their foraging areas, encompassing more than one biome and overcoming political borders. © 2008, Universidade Estadual de Campinas UNICAMP.All right reserved.16116134385/2005-5, CNPq, Conselho Nacional de Desenvolvimento Científico e TecnológicoConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Avaliação dos sistemas de informações do Departamento de Administração de Pessoal da UFMG

Os sistemas de informações são fundamentais para o bom andamento dos procedimentos e rotinas administrativas dentro de uma organização, sendo estes utilizados como base para a melhoria dos processos. Espera-se que as informações disponibilizadas por estes sistemas sejam confiáveis e de fácil acesso para as tomadas de decisão. Dessa forma, este trabalho teve por objetivo avaliar ossistemas de informação do Departamento de Administração de Pessoal (DAP), tendo como foco o Sistema Integrado de Administração de Recursos Humanos (SIAPE), o sistema PesSAUDE (Gestão de Auxílio- saúde ) e o sistema Plenus. A pesquisa foi elaborada no âmbito do Departamento de Administração de Pessoal da Universidade Federal de Minas Gerais e pautou-se nas seguintes perguntas de pesquisa: os sistemas SIAPE, PesSAUDE e Plenus satisfazem adequadamente asnecessidades de informações de seus usuários? Para atingir objetivo geral, foram utilizadas diversas metodologias, dentre elas, pesquisa documental, observação não-participativa, entrevistas e questionários. Os dados foram coletados por meio da análise das respostas dos questionários aplicados aos usuários dos sistemas, como também a partir da descrição de rotinas que utilizam estas ferramentas paraexecução de tarefas do departamento. Este estudo concluiu que estes sistemas precisam passar por melhorias para que atendam adequadamente os seus usuários. Os resultados apontam problemas e limitações em relação à utilização desses sistemas o que dificulta o bom andamento dos procedimentos administrativos e apresenta a necessidade de correções nessas ferramentas para que se alcanceeficácia na execução das tarefas do DAP

Limitations of chlorine disinfection of human excreta: implications for Ebola disease control

Various NGO guidelines suggest that human excreta may be disinfected by the application of concentrated (e.g., 0.5%) chlorine solutions. However, chlorine-based disinfectants are thought to rapidly lose their bactericidal and virucidal properties in contact with high levels of organic matter and chlorine application results in the production of toxic chlororganic compounds. To evaluate the disinfection efficacy of chlorine solutions (HTH, NaDCC and household bleach) against viruses and bacteria within excreta matrices, laboratory-scale disinfection experiments were undertaken. Human excreta matrices containing raw wastewater, with 0%, 10% and 20% (w/v) added faecal sludge, were disinfected with chlorine solutions at a ratio of 1:10 (chlorine solution: excreta matrix). Contact time was set at 30 minutes and bacterial (FC and IE) and viral (SOMPH) indicators were used to measure disinfection efficacy. Results demonstrated that at high levels of solids content, disinfection efficacy was significantly reduced. These results support the need to find a more effective means of disinfecting human excreta in future Ebola outbreaks
