25. Modeling body size evolution in Felidae under alternative phylogenetic hypotheses
The use of phylogenetic comparative methods in ecological research has advanced during the last twenty years, mainly due to accurate phylogenetic reconstructions based on molecular data and computational and statistical advances. We used phylogenetic correlograms and phylogenetic eigenvector regression (PVR) to model body size evolution in 35 worldwide Feli

26. Determinação de motivos de ligação à quitina em vicilinas de Canavalia ensiformis e Vigna unguiculata através de métodos in silico e relação com suas toxicidades para o bruquídeo Callosobruchus maculatus (Coleoptera:Bruchidae)
Chitin is an important structural component of the cellular wall of fungi and exoskeleton of many invertebrate plagues, such as insects and nematodes. In digestory systems of insects it forms a named matrix of peritrophic membrane. One of the most studied interaction models protein-carbohydrate is the model that involves chitin-binding proteins. Among the in

27. Multi-modelo de referência para planejamento em espectro de alta complexidade / A multi-model reference for planning high complexity spectrum
This thesis intends to contribute to the planning guidelines in the field of distance education (DE). Thus, it develops a multi-model reference proposal supported by the definition of a highly complex spectrum of strategies that considers a sequence of systematic procedures in the following phases: (i) Determining the information needs in two stages: (a) ide

28. Modeling and simulation of a fluidized bed : a comparative study / Modelagem e simulação de um leito fluidizado : um estudo comparativo
O objetivo deste trabalho foi o estudo comparativo de duas modelagens para representação de um escoamento gás-sólido. Na primeira modelagem avaliou-se uma correlação de arraste apresentada recentemente na literatura, baseada em simulações lattice Boltzmann, aplicada a escoamentos gás-sólido. Na segunda observou-se o efeito da variação do coeficie

29. Modelagem computacional de tomografia com feixe de prótons / Computational modeling of protons tomography
In the present work a preliminary research via computer simulations was made in order to elaborate a prior program for the first experimental pCT setup in Brazil. Proton therapy is a high precise form of a cancer treatment. Treatment planning nowadays is performed basing on X ray Computer Tomography data (CT), alternatively the same procedure could be perfor

30. UtilizaÃÃo de mÃtodos de transferÃncia de escala na simulaÃÃo de recuperaÃÃo de hidrocarbonetos com aplicaÃÃo de computaÃÃo distribuÃda
A transferÃncia para uma escala maior (âupscalingâ), tem sido um mÃtodo muito utilizado no tratamento de informaÃÃes associadas a uma grande quantidade de dados, tornando-se uma opÃÃo ainda mais relevante quando o excesso destes dados representa uma dificuldade na sua manipulaÃÃo, levando à outras conseqÃÃncias tais como longo tempo de p

31. A comparative kinetic study of SNCR process using ammonia
The paper presents comparative kinetic modelling of nitrogen oxides (NOx) removal from flue gases by selective non-catalytic reduction process using ammonia as reducing agent. The computer code SENKIN is used in this study with the three published chemical kinetic mechanisms; Zanoelo, Kilpinen and Skreiberg. Kinetic modeling was performed for an isothermal p

32. SAMPA (Systemn for Comparative Analysis of Metabolic PAthways) / SAMPA (System for Comparative Analysis of Metabolic PAthways) - uma comparação de vias metabólicas
The advent of genome sequencing technology and complete genome analysis has provided new data on prokaryote and eukaryote metabolic pathways. The comparative analysis of metabolic pathways from different organisms can help us understand inter and intra species organizational relationships. Having this in mind, this work focused on building a system that allo

33. Molecular modeling of arylpiperazine compounds and their interactions with the 5-HT1A receptor / Modelagem molecular de compostos arilpiperazínicos e suas interações com o receptor 5-HT1A
Selective serotonin reuptake inhibitors (SSRIs) are the most important class of antidepressants in current clinical use. However, they present the serious drawback of a delay of two to six weeks in the onset of therapeutic effect. Clinical studies have shown that when a 5-HT1A receptor antagonist is administrated along with a SSRI, an increase of extracellul

34. NUMERICAL MODELING OF VIRUS TRANSPORT IN FRACTURED-POROUS MEDIA / MODELAGEM NUMÉRICA DO TRANSPORTE DE VÍRUS EM AQÜÍFEROS FRATURADOS - POROSOS
Setback distances of wellhead and catchments from septic tanks are establised by three aproaches: methods based on fixed setback distances or fixed travel times; methods based on vulnerability analysis and methods based on infection risk. In Costa Rica, the determination of setback distances is based on fixed travel times. This approach considers that during

35. Estudo comparativo das aproximações baseadas no método de decomposição paramétrico para avaliar redes de filas de manufatura utilizando planejamento de experimentos / A comparative study of approximations based on the parametric decomposition method to evaluate manufacturing queueing networks using designing of experiments
This is a study of approximations based on parametric decomposition methods used in open queueing networks for modeling discrete job-shop manufacturing systems. These approximations play an important role in evaluating the performance of productive systems and have proved effective in many situations. Besides, these approximations are relatively easy to appl

36. Uma abordagem de metodos computacionais para simulação de processos biologicos : simulação tridimensional e metabolica do desenvolvimento tumoral / A computational approach for simulation of biological process : tridimensional simulation of tumor metabolism and development
In this work, we created a piece of software and computer models for studying carcinogenesis, in order to answer biological questions related to the treatment of this disease. The computer models were inspired in the theory of Somatic Evolution and Acid Mediated Tumor Invasion, proposed by Gatenby and Gillies, and were implemented in a tool developed by the
