1. A Comuputerized DRBEM model for generalized magneto-thermo-visco-elastic stress waves in functionally graded anisotropic thin film/substrate structures
A numerical computer model, based on the dual reciprocity boundary element method (DRBEM) for studying the generalized magneto-thermo-visco-elastic stress waves in a rotating functionally graded anisotropic thin film/substrate structure under pulsed laser irradiation is established. An implicit-implicit staggered algorithm was proposed and implemented for us

2. Virtual boundary method applied to a problem of computational aerolastic analysis / Método da fronteira virtual aplicado em um problema de análise aeroelástica computacional
The behavior study of a profile of a typical aerolastic section, with Reynolds in range of micro aerial vehicle, is the main focus of this work, taking as objective the estimation of parameters of flutter phenomenon. The research analyzes of the flow of a incompressible fluid on a body (cylinder and airfoil profile) at steady state and oscillating with const

3. Numerical solution of staggered circular tubes in two-dimensional laminar forced convection
This paper aims to demonstrate the importance of adequately estimating the discretization error intrinsic in the result of any numerical simulation. The problem under consideration is forced convection in a staggered circular tube heat exchanger. The problem is solved to analyze the effect of the distance between the tubes, aiming to optimize the heat exchan

4. A computacional tool for the modeling of prosthesis and bones using the poroelasticity theory / Elaboração de uma ferramenta computacional para modelagem de proteses e ossos atraves da proelasticidade acoplada
o modelo poro elástico é aplicado na representação do comportamento físico de um meio contínuo composto por duas fases distintas, uma sólida e outra fluida. A fase sólida está envolta em um domínio fluídico saturado. A matéria fluida presente no sistema pode ser líquida, gasosa ou uma mistura em função do meio a que se pretende estudar. Estrut

5. Solução numérica do modelo PTT para escoamentos viscoelásticos com superfícies livres / Numerical solution of the PTT model for viscoelastic surface flows
The aim of this work is to develop a numerical method capable of simulating viscoelastic free surface flows governed by the non-linear constitutive equation PTT (Phan-Thien-Tanner). In this work three numerical methods to simulate vicoelastic Flows of fluids modelled by the PTT equation are presented. Two of these methods were developed to simulate two-dimen

6. NUMERICAL ANALYSIS OF THERMO-HYDRAULIC PROBLEMS IN POROUS MEDIA / ANÁLISE NUMÉRICA DE PROBLEMAS TERMO-HIDRÁULICOS EM MEIOS POROSOS
The dissertation presents a study of the resolution of thermo-hydraulic coupling problems, through the use of numerical techniques. The study has the objective the implementations validation of the temperature gradients effects in the moisture flux. For this, the program UNSATCHEM-2D is used to simulate the flow of water in mediums of variable saturation to

7. Soluções não homogeneas das equações de Ginzburg-Landau em antiferromagnetos dopados
We propose a phenomenological model based on the Ginzburg-Landau theory of phase transitions, that describes the thermodynamic behavior of charge and spin density waves present in high-Tc doped antiferromagnets. One of the current ideas, supported by recent neutron scattering measurements, is that doping introduces charge excess that accumulates on the antif

8. Metodo dos volumes finitos aplicado a modelagem matematica e simulação computacional de um forno aquecido por jato de chama com escoamento em vortice
This thesis had the purpose of reaching a complementary k.nowledge of the intricate inter-relations between the complex phenomena of mass, momentum and energy transfers, which develop in furnaces with vortex flows, by mathematical modelling and computational simulation, in two and three-dimensional approaches. Furthermore, the effects of the bumer design and

9. Modelagem fenomenologica e simulação bidimensional de ciclones por tecnicas da fluidodinamica computacional
This work presents a mathematical modeling based on the principIes of mass and momentum conservation with the volumetric average point of view, and generalized to represent the multiphase flow in cyclones. It also discusses the hypotheses necessary for flutuating properties treatment, due to Reynolds decomposition applied as statistical treatment of the turb

10. Position-specific trapping of topoisomerase II by benzo[a]pyrene diol epoxide adducts: Implications for interactions with intercalating anticancer agents
DNA topoisomerase II (Top2) is the target of some of the most effective anticancer DNA intercalators. To determine the effect of intercalating ligands at defined positions relative to a known DNA cleavage site for human Top2α, we synthesized oligodeoxynucleotides containing single trans-opened benzo[a]pyrene 7,8-diol 9,10-epoxide (DE) deoxyadenosine (dA) ad

11. Amino-Acid Sequence of Rabbit Skeletal Tropomyosin and Its Coiled-Coil Structure
A tentative amino-acid sequence for the COOH-terminal half of rabbit skeletal tropomyosin is reported. These studies confirm our previous conclusions that this tropomyosin consists of several different but similar polypeptide chains. In the sequence, nonpolar residues occur in two series at intervals of seven residues. Amino-acid residues in series I are thr

12. Plasmic Degradation of Crosslinked Fibrin: CHARACTERIZATION OF NEW MACROMOLECULAR SOLUBLE COMPLEXES AND A MODEL OF THEIR STRUCTURE
Crosslinked fibrin was digested by plasmin, and three soluble complexes larger than DD/E were purified and characterized. After gel filtration chromatography, the purified complexes were shown to have molecular weights of 465,000, 703,000, and 850,000, as determined by equilibrium sedimentation. Each of the complexes was dissociated into two or more fragment
