1. Association of killer cell immunoglobulin-like receptor polymorphisms with chronic hepatitis C and responses to therapy in Brazil
Soroprevalence for Hepatitis C virus is reported as 2.12% in Northern Brazil, with about 50% of the patients exhibiting a sustained virological response (SVR). Aiming to associate polymorphisms in Killer Cell Immunoglobulin-like Receptors (KIR) with chronic hepatitis C and therapy responses we investigated 125 chronic patients and 345 controls. Additionally,

2. Genetic structure of drone congregation areas of Africanized honeybees in southern Brazil
As yet, certain aspects of the Africanization process are not well understood, for example, the reproductive behavior of African and European honeybees and how the first Africanized swarms were formed and spread. Drone congregation areas (DCAs) are the ideal place to study honeybee reproduction under natural conditions since hundreds of drones from various c

3. On the use of substructures in complex structures modeling. / Sobre o uso de subestruturas na modelagem de estruturas complexas.
In engineering, there are several structural analysis techniques leading to obtain displacements and efforts with a considerable degree of efficacy and accuracy, and, among these, there is the SUBSTRUCTURING technique. This method consists in the division and analysis of a complete structural model, by subdividing his field in SUBSTRUCTURES, allowing a consi

4. Evidence of lack of population substructuring in the Brazilian freshwater fish Prochilodus costatus
Curimbatá-pióa (Prochilodus costatus Valenciennes, 1850) is an endemic species from the São Francisco River Basin with migratory habits, important ecological role in the ecosystem and relevant fishing importance. The present study aimed to assess the genetic variation in P. costatus in order to investigate its population genetic structure. Genetic variati

5. ITS2 variability of Biomphalaria (Mollusca, Planorbidae) species from the Paranapanema Valley (São Paulo State, Brazil): diversity patterns, population structure, and phylogenetic relationships
The ribosomal DNA internal transcribed spacer 2 (ITS2) has been shown to be a useful genetic marker for species identification and phylogenetic reconstruction in the genus of freshwater snails Biomphalaria (Preston 1910). Additionally, ITS2 studies in Biomphalaria have uncovered significant intra-specific genetic variability suggesting the presence of crypti

6. Um Framework para Análise Seqüencial e em Paralelo de Sólidos Elásticos pelo Método dos Elementos Finitos
The objective of this work is the development of a C++ framework for finite element method (FEM) that provides sequential and parallel analysis of elastic solids. FEM is based on the discretization of the domain analyzed into a mesh, resulting on the transformation of the diferential equations that define elasticity into a linear equations system which for t

7. Evaluation of polymorphism in ten microsatellite loci in Uruguayan sheep flocks
The allele frequencies of 10 microsatellite loci previously described for sheep as BM1314, BM6526, OarFCB128, OarHH64, OarCP20, OarHH47, OarFCB48, OarHH35, OarHH72 and BM2508 were estimated for the Uruguayan flocks. A representative sample of 101 individuals composed by the two predominant breeds (76% Corriedale and 24% Australian Merino) was used. The sampl

8. Desenvolvimento e implementação de um software para análise tridimensional de edifícios altos em alvenaria estrutural
This work deals with the implementation of pre- and postprocessor program, which is based on CAD, where uses a processing program named CEASO 01 [TORRES(1999)] to analyze tall buildings in masonry structures. The program CEASO 01 considers the use of thin-walled element of open cross section and space frame element to represent the groups of structural walls

9. Desenvolvimento de algoritmos de subestruturação para elementos finitos
In Engineering many physical phenomena are modeled using differential equations. The finite element method is very efficient to solve these equations numerically. Many applications lead to very large problems, whose solution requires specialized methods. The most recent tool for solving large scale problems is the parallel processing. This tool is used toget

10. Microsatellites reveal high levels of population substructuring in the species-poor Eretmodine cichlid lineage from Lake Tanganyika.
This study investigated fine-scale population substructuring in an apparently monogamous, biparental mouth-brooding cichlid. Microsatellite allele frequencies were determined at four polymorphic loci for nine populations of Eretmodus cyanostictus. We provide empirical support for the hypothesis that a species employing this breeding strategy should exhibit h

11. Population Studies on an Endemic Troglobitic Beetle: Geographical Patterns of Genetic Variation, Gene Flow and Genetic Structure Compared with Morphometric Data
Highly specialized obligatory cave beetles endemic to the French Pyrenees offer an opportunity to investigate the relative importance of environmental conditions and ecological characteristics on the organization of genetic variability, to describe the genetic structure of populations, and to assess the extent of gene flow between local populations in relati

12. Population Genetic Consequences of Feeding Habits in Some Forest Lepidoptera
By surveying variation at allozyme loci in several phytophagous lepidopteran species (Geometridae), we have tested two hypotheses about the relationship of genetic variation to environmental heterogeneity: (1) that allozyme polymorphisms may exist because of associations between genotypes and "niches" (different host plants, in this instance), and (2) that t
