26. Development of numerical model for the simulation of water-quality at rivers, using the software Vensim PLE® / Desenvolvimento de modelo numérico para a simulação da qualidade da água em rios utilizando o software Vensim PLE
The water-quality modeling is an indispensable tool for the water resource planning and management. However, the current available models for the simulation of water-quality, as the QUAL2K, present structural and functional limitations. With the purpose of offering a tool that facing those deficiencies, a model for time-variable simulation of the rivers wate

27. Avaliação de modelo de tomada de decisão para escolha de sistema de tratamento de esgoto sanitário / Evaluation of decision-making model to choice system for treatment of sewage
A solution for the preservation of the water is the investment in sanitation and in the treatment of sanitary sewer, which is accomplished through sewer treatment stations. However, the choice of the treatment system to be implanted in a municipal district should meet its technical, environmental, social and economical requirements. The main objective of thi

30. THE AHP - CONCEPTUAL REVIEW AND PROPOSAL OF SIMPLIFICATION / O MÉTODO AHP - REVISÃO CONCEITUAL E PROPOSTA DE SIMPLIFICAÇÃO
Several transportation problems, as well as problems in other knowledge areas, request decision making. In complex decisions, the choice of best alternative or course of action can contain more than one criterion and it is necessary to study how each alternative affects each criterion. The AHP, Analytic Hierarchy Process, proposed by Thomas L. Saaty, is a mu

31. MÉTODOS APROXIMADOS DE SOLUÇÃO DE SISTEMAS DINÂMICOS NÃO-LINEARES / APPROXIMATE SOLUTION METHODS FOR NONLINEAR DYNAMICAL SYSTEMS
Nonlinear dynamical systems are rather common in engineering. This class of problems is usually solved by numerical integration or through the use of ap- proximate analytical methods (perturbation methods) or semi-analytical meth- ods such as the harmonic balance method. The numerical integration is a slow and cumbersome process in parametric analyses. The o

32. Estudos quÃmico e bioquÃmico do yacon (Smallanthus sonchifolius) âin naturaâ e processado e influÃncia do seu consumo sobre nÃveis glicÃmicos e lipÃdeos fecais de ratos / Chemical and biochemical studies of in natura and processed yacon (Smallanthus sonchifolius) and influence of its consumption on glucemic levels and fecal lipids of rats
Research on foods which can aid in the prevention and treatment of pathologies, mainly the non-transmissible chronic diseases, have been being more and more frequent. Seeking to increase the knowledge on yacon, this work was aimed to study that root and evaluate the influence of yacon pulp flour in the possible reduction of post-prandial glucemia and increas

34. Effects of solar neutrinos scale on atmospheric neutrino flux
In this work we try to understand the phenomena of neutrino oscillations, and use this to obtain a more precise description of the atmospheric neutrino data. The two neutrino oscillation mechanism solves the problem of the up-down muon neutrino asymmetry successfully. Our main motivation is to describe the excess of events of electron-neutrino type found in

35. The analysis of verbal contents to the solution of difficulties in anxious patients / Análise de conteúdo verbal na solução de dificuldades de portadores de transtornos ansiosos
Verbal behavior comprehension is crucial to the analysis of dysfunctional behaviors attended in behavior analytic therapy. Studies of verbal report studies on clinical context, have showed the importance of the use of verbal behavior and have generated intervention procedures to solve problems. Self-reports reinforcement, as a function of reinforcement conti
