14. IMPERMEABILIZAÇÃO DAS SUPERFÍCIES DE CONTATO PARA IMPLANTAÇÃO DE ESTRUTURAS DE CONCRETO EM MACIÇO DE ROCHA SULFETADA - O CASO DA UHE IRAPÉ -
The water that percolates through acid sulfate rock masses can become chemically aggressive to concrete, thereby compromising some of its characteristics, such as watertightness and strength. The presence of acid sulfates in the rock mass at the installation site of the Irapé Hydroelectric Power Plant led to the study and implementation of protective measur

15. Desenvolvimento de um sistema para diagnostico preventivo de laminite em bovinos de leite utilizando logica Fuzzy / Development of a system for preventive diagnosis of lameness in dairy cattle using fuzzy logic
From the middle of the 20th century experts on genetics and producers had intensified the work to improve dairy production. Advances have appeared, however these results have not been followed by the improvement of cows legs and hooves. The intensification of herd?s needs have been carried through housing modifications aiming at to adjust them as well as to

16. Análise dos biótopos da bacia hidrográfica do córrego Águas Espraiadas-São Paulo - SP / Analysis of the Biotopes in hidrographic basins from the stream Águas Espraiadas
This work shows the importance of environmental preservation in urban areas. In this way, was developed the study of waterproofing of lots inserted in biotopes (units of landscape) found in the hydrographic basin of the Stream of Águas Espraiadas, which today is totally urbanized. A historical and ambiental characterization of the studied area was developed

18. "Estudo comparativo da resistência à infiltração que diferentes materiais resinosos utilizados na cimentação de retentores intra-radiculares oferecem à passagem de fluidos que atravessam a dentina" / Comparative study of the infiltration resistance that different resinous materials used in intra-radicular retainers foundation offer to the fluids passage that cross through the dentine.
This study objective is to evaluate in vitro, the resistance that different resinous materials have through the fluids passage cross through the dentine in the absence of radicular cementum. 60 human teeth given by FOUSP bank of teeth were used. The teeth were submitted to endodontic treatment according to Paiva s and Antoniazzi´s technique and stored in a

19. Chemical and physical analyses of wax ester properties
Wax esters are major constituents of the surface lipids in many terrestrial arthropods, but their study is complicated by their diversity. We developed a procedure for quantifying isomers in mixtures of straight-chain saturated and unsaturated wax esters having the same molecular weights, using single-ion monitoring of the total ion current data from gas chr
