1. In silico Antibacterial Activity Modeling Based on the TOMOCOMD-CARDD Approach
In the recent times, the race to cope with the increasing multidrug resistance of pathogenic bacteria has lost much of its momentum and health professionals are grasping for solutions to deal with the unprecedented resistance levels. As a result, there is an urgent need for a concerted effort towards the development of new antimicrobial drugs to stay ahead i

2. Simulação numérica de equações de conservação usando esquemas \"upwind / Numerical simulation of conservations equations using upwind schemes
Uma família de esquemas upwind denominada FUS-RF (Family of Upwind Scheme via Rational Functions), que é derivada via funções racionais e dependentes de parâmetros, é proposta para o cálculo de soluções aproximadas de equações de conservação. A fim de ilustrar a capacidade dos novos esquemas, vários resultados computacionais para sistemas hiper

3. Estabilidade e estabilização de uma classe de sistemas não-lineares sujeitos a saturação
This work addresses the problem of stability analysis and stabilization of nonlinear rational systems subject to saturation. The approach used in this study is based on the differential algebraic representation (DAR) of rational systems and on a modified version of the generalized sector condition to deal with saturation. First, methods to characterize the s

4. Mecanismos intraflagelares de transporte e trânsito de proteínas: uma abordagem pós-genômica e computacional de caracterização da virulência flagelar em Leishmania spp. / Intraflagelares mechanisms of transport and transit proteins: a post-genomics and computational characterization of virulence flagellar Leishmania spp.
Leishmania are flagellated protozoa that cause a main neglected diseasease, collectively known as leishmaniases, posing a constant challenge for the control and prevention of the disease due to the wide-world distribution and prevalence of these parasites. As an insinuating pathogen, Leishmania has a specialized organelle for motility, the flagellum, which i

5. Uma abordagem funcional para o ensino de inequações no ensino médio
This qualitative research was conducted with students undergoing the second year if Senior High School in a private school in the south area of São Paulo. We looked for answers to the following questions: Up to what extent does the teaching of inequalities through a functional graphic approach, which involves the treatment and conversion of registers of sem

6. A alma espiritual como forma substancial do corpo no ser humano segundo Tomás de Aquino
The human soul, as spiritual substance, both in its being and its operations, unites to the body as its form, and thus lends man his vegetative, sensible and intellectual life. The soul as first act brings about being; thus, through this first act, the living being, can exercise its second acts, as are its vital functions and the operative potentials. But th

7. Descartes e a demonstração da impossibilidade da reprodução mecanica da inteligencia / Descartes and the demonstration of the impossibility of the mechanical reproduction of intelligence
The present study is an analysis of the work of Descartes from that what it has most controversial of the mind-body problem. The metaphysical experiment, that leads Descartes from the discovery of the Cogito to the discovery of God and the world, allows the philosopher to derive three fundamental consequences: a) the mind is from immaterial nature (res cogit

8. State-Space modeling and active aeroelastic control of a typical airfoil section with three degrees of freedom.
This dissertation presents a detailed analysis of a typical section model with three degrees of freedom. This is a classic model used for the study of basic aerodynamic and aeroelastic phenomena. The equations of motion are derived and discussed. The equations for the aerodynamic loads induced by arbitrary motion of the typical section and by arbitrary shape

9. Biophysical and structural studies on aspartic proteases from pathogenic parasites. / Estudos biofísicos e estruturais de aspartil proteases de parasitas patogênicos.
The purpose of this study is to compare the structure of aspartic proteases of Plasmodium falciparum and Schistosoma mansoni in different chemical environments in order to provide relevant information for future rational design of new drugs and new knowledge about the folding and dynamism of structural proteins. For this, changes in secondary and tertiary st

11. Avaliação dos gastos realizados pelo Ministério da Saúde com medicamentos de alto custo utilizados no tratamento da drc por pacientes do SUS no Estado de Minas Gerais 2000 a 2004
Introdution: The chronic kidney disease is represented for irreversible and slow loss of kidney functions. In Brazil, the treatment for this illness is supplied by Unique Health System (SUS) and included dialyses and kidney transplant, beyond the use of medicines for treatment of resulting complications of kidney diminution of function. In 2000, 6% of the to

12. Análise do Universo imaginário de Professores de Matemática: Entre Luzes e Sombras
This thesis presents the results of research conducted on the mapping and analysis of the structure of the imaginarium of mathematics teachers in the state school system in the city of Recife, relating these mathematical presuppositions to the mythical structures with which they work. Interpreting imaginarium as a place dentre-savoirs stemming from the exist
