13. Estudo dos parâmetros do decaimento do cloro residual em sistema de distribuição de água tratada considerando vazamento / Study of the residual decay parameters in water distribution systems with leakage
The use of chlorine as disinfectant in water supply systems has been a common practice adopted by the water industry. Introduced during the treatment process, chlorine participates in several reactions with compounds of organic and inorganic nature inside the pipes. Such reactions that occur in the bulk and the wall of the pipes are responsible for chlorine

14. Simulação e otimização de reator de formaldeido, processo prata, usando tecnicas de inteligencia artificial / Simulation and optimization of silver formaldehyde reactor, using artificial intelligence techniques
The focus of this Thesis is the simulation and optimization of a silver catalyzed fixed-bed reactor for the oxidation of methanol to formaldehyde, using artificial intelligence techniques (genetic algorithm and artificial neural networks). Formaldehyde is a key chemical intermediate used mainly in the production of adhesives and resins for several market seg

15. Albedo of an Amazon tropical rainforest: field measurements, remote sensing, modeling, and its influence on the regional climate / Albedo de uma floresta tropical Amazônica: medições de campo, sensoriamento remoto, modelagem, e sua influência no clima regional
Albedo is defined as a ratio between reflected solar radiation and incoming solar radiation over a surface. It is a main factor that affects the terrestrial radiation balance and has been frequently considered in the global and regional climate studies. Amazon is one of planets regions where the response of regional atmospheric circulation is more intense. S

17. Physical and numerical simulations of the rotary continuous casting process / Simulação fisica e numerica do processo de lingotamento continuo rotativo
The present study describes the development of a static experimental set-up representing the solidification system of a Rotary Continuous Caster, as part of a metholology, which connected to a numerical model permits to determine transient global metal/mold heat transfer coefficients along solidification. By using this methodology the influence of air gap fo

19. Geographic data bank and artificial neural network: technologies of support for the territorial management. / Bancos de dados geográficos e redes neurais artificiais: tecnologias de apoio à gestão do território.
This work presents the development of a tool to support the land management called Geographical Data Base (GDB) formed by a georrefered data base, a data base management system (DBMS), a geographic information system (GIS) and an artificial neural net simulator (ANNS). The methodological approach allowed the conceptual modelling of the methodology of the ZEE

20. Use of a Continuous-Flow Anaerobic Culture To Characterize Enteric Virulence Gene Expression
We developed an in vitro culture method to characterize the expression of bacterial genes under conditions mimicking the colonic environment. Our culture system (the intestinal simulator) comprised a continuous-flow anaerobic culture which was inoculated with fecal samples from healthy volunteers. As a test organism, we employed enteroaggregative Escherichia
