13. Patossistema caupi X Macrophomina phaseolina: método de detecção em sementes, esporulação e controle do patógeno. / The pathosystem cowpea x Macrophomina phaseolina: detection in seeds, esporulation and pathogen control.
Notwithstanding the specie Vigna unguiculata (L.) Walp is sufficiently rustic and adapted to the adverse conditions of the Brazilian soil and climate, its improvement is very low. Many causes have been raised in order to explain such behavior; among them the fungal diseases stand out, over all those whose pathogens are transmitted by the seeds especially the

14. Dinamica de sistemas quanticos : atomos em cavidades de ions aprisionados
In this thesis we studied the dynamics of two quantum systems: atoms in a cavity and trapped ions. For atoms in a cavity ( QED ) , we studied the dynamics of field prepared in a superposition of coherent states and a statistical mixture. In this system, using a Intensity-Dependence Jaynes-Cummings model (DNJCM) we discuss some aspects of the dynamics of atom

15. IMPLEMENTACIÓN NUMÉRICA PARA EL ESTUDIO DE FUNDACIONES FLEXIBLES EN SUELOS ESTRATIFICADOS / NUMERICAL ANALYSIS OF FLEXIBLE FOOTINGS ON STRATIFIED SOILS / IMPLEMENTAÇÃO NUMÉRICA PARA ESTUDO DE FUNDAÇÕES FLEXÍVEIS EM SOLOS ESTRATIFICADOS
Many problems of geotechnical engineering can be solved by superposition of the fundamental singular solutions to the governing differential equations. In the dissertation, the mechanical behavior of a flexible footing is investigated, in terms of stress and settlement distributions, considered some basic fundamental solutions published in literature. These

16. Interação dinamica de estruturas bidimensionais com o solo : uma comparação entre um metodo semi-analitico e o metodo dos elementos de contorno
In this work two methods to treat the dynamic soil-structure interaction phenomena are compared: a Superposi tion Method (SPM) and the Boundary Element Method (BEM) .Complete compliances matrices for the dynamic interaction of bidimensional surface and embedded foundation structures, interacting through the soil in frequency domain are obtained. A discussion

17. SuperPose: a simple server for sophisticated structural superposition
The SuperPose web server rapidly and robustly calculates both pairwise and multiple protein structure superpositions using a modified quaternion eigenvalue approach. SuperPose generates sequence alignments, structure alignments, PDB (Protein Data Bank) coordinates and RMSD statistics, as well as difference distance plots and images (both static and interacti

18. The Structure Superposition Database
The need for new tools for investigating biological systems on a large scale is becoming acute, particularly with respect to computationally intensive analyses such as comparisons of many three-dimensional protein structures. Structure superposition is a valuable approach for understanding evolutionary relationships and for the prediction of function. But wh

19. Response experiments for nonlinear systems with application to reaction kinetics and genetics
A unified type of response experiment is suggested for complex systems made up of individual species (atoms, molecules, quasi-particles, biological organisms, etc.). We make the following assumptions: (i) some of the species may exist in two forms, labeled and unlabeled, respectively; (ii) the kinetic and transport properties of the labeled and unlabeled spe

20. Bayesian image reconstruction for emission tomography incorporating Good's roughness prior on massively parallel processors.
Since the introduction by Shepp and Vardi [Shepp, L. A. & Vardi, Y. (1982) IEEE Trans. Med. Imaging 1, 113-121] of the expectation-maximization algorithm for the generation of maximum-likelihood images in emission tomography, a number of investigators have applied the maximum-likelihood method to imaging problems. Though this approach is promising, it is now

21. The invariant system of coordinates of antibody molecules: prediction of the "standard" C alpha framework of VL and VH domains.
A new approach of comparing protein structures that does not involve the procedure of superposition is suggested. An invariant system of coordinates for immunoglobulin molecules that is based on the geometrical symmetry inherent to the variable domain light-chain (VL)-heavy-chain (VH) complex is described. The coordinates of the Calpha atoms in 22 immunoglob

22. Evaluating conformational free energies: The colony energy and its application to the problem of loop prediction
In this paper, we introduce a method to account for the shape of the potential energy curve in the evaluation of conformational free energies. The method is based on a procedure that generates a set of conformations, each with its own force-field energy, but adds a term to this energy that favors conformations that are close in structure (have a low rmsd) to

23. Antibody remodeling: a general solution to the design of a metal-coordination site in an antibody binding pocket.
To develop a general approach to designing cofactor-binding sites for catalytic antibodies, we characterized structural patterns in the binding sites of antibodies and zinc enzymes. Superposition of eight sets of antibody light- and heavy-chain variable domains identified structurally conserved sites within the sequence-variable complementarity determining r
