26. Modelagem dos fenômenos de transporte termo-hídricos em meios porosos submetidos a temperaturas elevadas : aplicação a uma bicamada rocha-concreto
Concrete is an extremely complex material, whose properties are not yet fully understood. The diculties in describing and predicting the behavior of concrete structures are due to aspects related to the heterogeneity of medium - which is porous and multiphase - presenting uids in liquid and gas forms. When exposed to high temperature conditions, such diculti

27. Fluxos hídricos na microbacia do córrego do Queixada no município de Jataí / Water flows in the stream watershed queixada in the city of Jataí (Go)
The diagnosis of hydrological flow and the rainfall interception by vegetation is justified by the need for knowing the influence of these elements in river basins, where weeds and appropriate use of land are responsible for maintaining the quality of the slopes, avoiding erosion, soil loss, silting of waterways and induces the maintenance of groundwater res

29. A dinâmica do fitoplâncton em uma várzea Amazônica variações sazonal e nictimeral (Várzea do Lago Grande de Curuai Pará, Brasil) / The dynamics of phytoplankton in an Amazon fllodplain - seasonal and nictemeral variations (Lago Grande de Curuai - Pará, Brasil)
The river-floodplain systems are environments submitted a lateral overflow of river channel due the rains and/or underground waters. They are controlled by the type of climate, morphology and local effects. The lowland lakes are also highly productive because of the rich sources of primary carbon. The sediments transport and suspended and dissolved matter ar

30. Removal of diuron and hexazinone from guarany aquifer groundwater
The economy of many communities in southeastern Brazil is based on agroindustry, particularly the sugarcane industry. Recent studies have found increased use of herbicides in this type of agriculture, among which diuron and hexazinone are the most widely used. The water supply for some communities is derived entirely from the Guarany Aquifer (the world's lar

32. Concentrações de randônio nas águas subterrâneas, rochas e solos de Porto Alegre, RS
Many water-supply systems in Brazil utilize groundwaters at least as part of their networks. This is the case of Porto Alegre, capital of Rio Grande do Sul State, whose population is about 1.4 million inhabitants. However, there is little present knowledge in Brazil of the factors affecting Rn presence in the water supplied for end-users, despite the economi

33. Environmental drivers of leaf phenology in trees of the tropical species Ficus obtusifolia
Vegetative as well as reproductive phenology of tropical trees frequently occur synchronously at the end of the dry season. It has been repeatedly observed on two individuals of the tropical species Ficus obtusifolia growing in Caracas that they lose their entire foliage in a period of 48 h during the dry season and renew it within the next 72 h. In order to

34. ANÃLISE TÃCNICO-ECONÃMICA DA RECUPERAÃÃO DE UM SOLO SÃDICO NO PERÃMETRO IRRIGADO CURU-PENTECOSTE-CE / Techno-economical analysis of the reclamation of a sodic soil in the Irrigated Perimeter Curu-Pentecoste-CE.
In the semi-arid part of Northeastern Brazil, the highest incidences of salinized areas are observed in land subjected to intense irrigated cultivation, in the âPerÃmetros Irrigadosâ (irrigated perimeters), particularly those where is used the surface method. The experiment was performed in the âNÃcleo Dâ (D Core) of the âPerÃmetro Irrigado Curu-Pent

35. Modelagem computacional e calibraÃÃo da condutividade hidrÃulica horizontal em aqÃÃfero da Bacia Sedimentar do Araripe utilizando o mÃtodo iterativo do gradiente hidrÃulico / Computational modeling and calibration of water-bearing the horizontal hydraulical condutividade in of the Basin Sedimentary of the Araripe using the iterative method of the hydraulical gradient
O processo de calibraÃÃo de parÃmetros hidrodinÃmicos representa parte importante dos modelos e sua abordagem geral consiste em minimizar uma funÃÃo objetivo expressa pela diferenÃa entre as cargas hidrÃulicas observadas e calculadas. Guo e Zhang, na dÃcada de 90 e, depois, Schuster e AraÃjo (2004) propuseram um processo alternativo para estimaÃÃ

36. The burrows of Parastacus defossus (Decapoda: Parastacidae), a fossorial freshwater crayfish from southern Brazil
Parastacus defossus Faxon, 1898 is a fossorial crayfish species, which constructs its burrows in swampy areas in southeast Uruguay and in the state of Rio Grande do Sul, Brazil. The present field study was carried out in Lami, Porto Alegre, Rio Grande do Sul, Brazil, from May 2003 through August 2005. Environmental measurements (temperature, pH, dissolved ox
