25. Controlled disposal of effluent domestic sewage in the ground a study of the reduction of fecal coliforms / Disposição no solo de efluentes de esgoto tratado visando a redução de coliformes termotolerantes
The indiscriminate launching in the water courses of sewers domestic without treatment, or exactly treat, but without appropriate disinfection, contributes with significant amount of organisms of the called "coliform group", between which specific agents of illnesses of water propagation can be present. The application of the effluent in the ground, instead

26. Water losses in public water network supply : diagnostic, control and reduction method by the geographic information system / Perdas fisicas de agua em sistemas de abastecimento : metodo de diagnostico, controle e redução atraves de sistema de informações geograficas
Nowadays, the water for human consumption has been adding social and economic considerable values, due to its strategic relationship between the increasing demand in detriment to the offer, tending to scarcity, mainly in the big centers, so the occurrence of high levels of physical losses, in the water supply system (WSS), has become a great problem to be fa

27. Ecophysiological attributes of hybrid DKB-390 and sthocastic model for predicting grain productivity / Atributos ecofisiológicos do híbrido DKB-390 e modelo estocástico para previsão da produtividade de grãos
Maize is on of the world most important crops, given that the products generated from this cereal are largely used by sectors like starch industry, animal and human nutrition, as well as biomass energy production and refineries. For these reasons, there is frequently a huge interest in knowing the potential adoption of the main available genotypes in relatio

30. Occurrence and removal of endocrine disruptor compounds in drinking water at Campinas and Sumare, Sao Paulo State, Brazil / Ocorrencia e remoção de disruptores endocrinos em aguas utilizadas para abastecimento publico de Campinas e Sumare - SP
The occurrence of potential endocrine disruptor compounds (EDC) in wastewater treatment plant (WWTP) effluent and surface waters at high concentrations harmful for aquatic life has been an interesting research field due to the probability of these micro pollutants to break through water treatment plant (WTP). The present paper evaluated the occurrence of nat

31. Evaluation of the water quality Index (WQI) and chemical elements in the water and in the sediments of Corumbataí river-SP / Avaliação do índice de qualidade da água (IQA) e dos elementos químicos nas águas e nos sedimentos do rio Corumbataí-SP
The Corumbataí River, main tributary of the Piracicaba river and source of water supply to the city of Piracicaba has been suffering degradation from its waterhead in the city of Analândia to its mouth in the Piracicaba river. In 2005 and 2006 were determined the concentration of the elements, Be, Al, Na, Mg, Ca, K, V, Mn, Fe, Cr, Co, Ni, Cu, Zn, As, Se, A

32. IrrigaÃÃo e fertirrigaÃÃo em um sistema de aspersÃo convencional submetido à tÃcnicas de controle estatÃstico de qualidade. / Irrigation and fertigation in sprinkler system submitted to techniques of statistical quality control
The contribution of irrigation in the alimentary supply, is due to the fact of more and more to look for more efficient systems, monitoring the indexes of uniformity of distribution of the water. The application of fertilizers through irrigation water took very big pulse in the last times, mainly due to the emergence of pressurized systems, of the tunnels of

33. Monitoring fails in tubes using signals digital processing / Sistema de monitoramento de falhas em tubulações por meio de processamento digital de sinais
Natural gas has hazardous contaminants that, besides being corrosive, compromise the quality for the consumption. For in such a way the present residual water condensation in the gas can start a local corrosive process, which could cause damage to the structure of the gas ducts. Due to the great length of a gas duct, corrosive components decrease its quality

34. DinÃmica de nutrientes em solos arenosos adubados com esterco bovino por longos perÃodos / Dynamics of nutrients in sandy soils amended with cattle manure for long periods
Additions of farmyard manure (FYM) to the soil are a widely adopted alternative to supply nutrients, particularly nitrogen and phosphorus, in areas of subsistence agriculture in the semi-arid and agreste of Paraiba State. Additions of this residue in quantities that far exceed crop uptake, for long periods, can cause accumulation of nutrients in the soil. Th
