O presente estudo foi realizado na Bacia Hidrográfica do Rio Passa-Cinco, onde existem elementos da paisagem de grande interesse ecoturístico, além de patrimônios naturais que, se preservados e aproveitados mediante ações de gestão ambiental serão potenciais agentes de desenvolvimento sustentável na região. Apesar da área possuir atrativos naturais como cachoeiras, corredeiras, cavernas, canions, lagos, paredões, mirantes, entre outros, indicando alto potencial de uso sustentável do ponto de vista ecoturístico, a região ainda não recebeu investimentos suficientes para que toda a diversidade paisagística seja usufruída. Portanto, este trabalho tem o objetivo de elaborar um Inventario Ecoturístico da Bacia do Rio Passa-Cinco, inserido nos municípios de Itirapina-SP e Ipeúna-SP, utilizando ferramentas de Geoprocessamento. Para tanto, realizou-se um trabalho de campo com visita aos locais que apresentam valor cênico considerável e potencial ecoturístico. Os locais identificados e visitados foram caracterizados usando fotografias, textos explicativos, tabelas e MDTs (Modelo Digital de Terreno). A integração destas informações constitui um Banco de Dados Geográfico Digital Georreferenciado (BDGDG) em ambiente ArcGIS 9.0, disponível em http://ceapla.rc.unesp.br/atlas/. Os resultados obtidos subsidiam ações de gestão ambiental, como o planejamento ecoturístico na bacia, favorecendo o desenvolvimento sustentável das comunidades envolvidas. Palavras-chaves: Bacia do Rio Passa-Cinco, Inventário Ecoturismo, Geoprocessamento, Banco de Dados Geográfico Digital Georreferenciado.

This study aimed to evaluate the potential of CH4 and CO2 in vitro production of soybean hulls, sunflower meal, corn, citrus pulp and corn silage. Four rumen-cannulated sheep were fed diets containing the evaluated ingredients at 40:60 forage:concentrate ratio. The gases produced by samples incubation were measured by injection into a gas chromatograph equipped with flame ionization detector. The experimental design was completely randomized with repeated measures, with three replicates for each evaluated food at four different periods. Under the experimental conditions, we verified different potential gas production among the ingredients. The citrus pulp meal was the ingredient with the greatest potential for CO2production. Corn silage and soybean hulls showed the greatest potential while citrus pulp and sunflower meal showed the least potential for CH4 production, when expressed in mL/g of degraded dry matter; therefore, they can be considered, among the evaluated ingredients, those with the lowest environmental impact.

The proposal of this study was to compare a wound healing between conventional suture and vaporization with CO2 laser in rats skin. ln such case 24 rats were utilized, making two longitudinal incisions in dorsum by scalpel. ln the left side incision the wound was sutured with nylon thread. ln the right side incision the wound were close by approach and vaporized with C02 laser, defocusing, 8 watts in continuous mode. The wound healing was followed by clinical photographic taking at the times: immediately after the procedure, 24 hours, 3, 7, 14, and 21 days. The results showed an early delay of reparation in healing vaporized in comparison with the sutured one, however occurred 21 days both repair tissue showed the same clinical characteristic. This results suggested that the C02 laser can be used by eventual substitute of suture.

The study of organic matter and its compartments and their relationship with management, aims to develop strategies for increasing their levels in soils and better understanding of its dynamics. This work aimed to evaluate the fractions of soil organic matter and their carbon stocks in different soil cover system in crop-livestock integration and native Cerrado vegetation. The study was conducted at the farm Cabeceira, Maracaju-MS, sample area have the following history: soybean/corn + brachiaria/cotton/oat + pasture/soybean/formation of pasture/grazing, sampling was carried out in two seasons, dry (May/2009) and rainy (March 2010), in the dry season, crops present were: pasture, corn and cotton + brachiaria and in the rainy season were corn, cotton and soybeans, so the areas in the two evaluation periods were: pasture / maize + brachiaria / cotton, cotton / soybean area and a native of Savanna. Was performed to determine the exchangeable cations, particle size analysis, bulk density, organic carbon, particle size fractionation of organic matter of the soil with the quantification of particulate organic carbon (POC) and organic carbon associated with minerals (OCam). Was also quantified the carbon stock and size fractions. The area of pasture / maize showed higher carbon stock in the particulate fraction in the topsoil. The area of cotton / soy due to its lower clay, showed the greatest loss of carbon. Because of the areas have the same history, the stock of more recalcitrant fraction was not sensitive to variations in coverage. The POC fraction appears more sensitive to different soil covers and seasonality.
