1. Plasmid-mediated quinolone resistance (PMQR) and mutations in the topoisomerase genes of Salmonella enterica strains from Brazil
The objective of this study was to identify mutations in the Quinolone Resistance Determining sources Regions (QRDR) of the gyrA, gyrB, parC, and parE genes and to determine if any of the qnr variants or the aac(6')-Ib-cr variant were present in strains of Salmonella spp. isolated in Brazil. A total of 126 Salmonella spp. strains from epidemic (n = 114) and

2. Association of hepatitis C virus NS5B variants with resistance to new antiviral drugs among untreated patients
Mutations located in the 109-amino acid fragment of NS5B are typically associated with resistance to interferon (IFN) and ribavirin (RIB) and to new antiviral drugs. The prevalence of these mutations was examined in 69 drug-naïve individuals with hepatitis C virus (HCV) infections in Rio de Janeiro, Brazil. Mutations related to non-response to IFN/RIB were

3. "Efeito da deformaÃÃo plÃstica no processo de seleÃÃo de variantes na transformaÃÃo martensÃtica no aÃo inoxidÃvel austenÃtico AISI 301L" / " Effect of the plastic deformation in the process of variants selection in the martensitic trasnformation in the austenitic stainless steel AISI 301L"
O presente trabalho visou estudar o efeito da deformaÃÃo plÃstica prÃvia por laminaÃÃo e o efeito da deformaÃÃo por traÃÃo no processo de seleÃÃo de variantes durante a transformaÃÃo martensÃtica no aÃo inoxidÃvel austenÃtico AISI 301L. Foram comparadas amostras previamente laminadas e deformadas em ensaio de traÃÃo com amostras apenas de

4. Análise de expressão e splicing alternativo do gene Mdh-1 de Apis mellifera L. (Hymenoptera: Apidae)
Mdh-1 enzyme locus coding for cytoplasmic malate dehydrogenase has three common alleles Mdh-1100 (F), Mdh-180 (M) e Mdh-165 (S) and it has been extensively used as racial marker in populational studies of Apis mellifera. Additional isoforms are detected by electrophoretic analysis during ontogenetic development of A. mellifera, indicating differential expres

5. Texture analysis of deformation induced martensite in an AISI 301L stainless steel: microtexture and macrotexture aspects
Experiments have been conducted to study the strain induced transformation from austenite to martensite in a metastable AISI 301LN austenitic stainless steel, deformed by uniaxial tension applied along rolling direction. Samples deformed 10 and 20% have shown the presence of α´ martensite phase. Measured pole figures of martensite phase were compared to ca

6. InduÃÃo de mutaÃÃo em feijÃo-caupi [Vigna unguiculata (L.) Walp., cultivar BR-14 mulato, visando à obtenÃÃo de mutantes tolerantes à salinidade
Among cultivated bean varieties cowpea [Vigna unguiculata (L.) Walp.] stands out for its high protein content and its ability to grow under adverse conditions. As such, this species has become one of the most important subsistence crops for rural populations in Brazilian north-eastern region. However, aside from increasing environmental problems, soil salini

7. O entrelaçar coesivo e a variação lingüística: um percurso didático-metodológico à luz da linguística textual
Based on the theoretical presuppositions of Textual Linguistics and grounded on postulates of the varied Socio-Linguistics, this research wishes to cause a reflection on the possibility of approximation between theory and practice, from verifying the results obtained from texts written by first-year high school students, diastratic linguistic variation users

8. 3D image registration of the human brain / Registro de imagens 3D do cerebro humano
Image Registration is the process that aligns two or more images in a common reference system of spacial coordinates [31]. It is an important problem with several applications in Medical Imaging, enabling, for instance, the analysis of changes in anatomy along time by the registration of images from the same modality, and the study of combined anatomic and p

9. Extensões da estatística scan espacial utilizando técnicas de otimização multi-objetivo
This work presents three new extensions of Kulldorffs Spatial Scan Statistic for the detection and inference of spatial clusters. Consider a map divided into m regions with known populations at risk and number of cases of some disease. We would like to know if the cases are randomly distributed over the m regions or not; if the cases are not randomly distrib

10. Automatically composing reusable software components for mobile devices
Product-line architectures (PLAs) are an effective mechanism for facilitating the reuse of software components on different mobile devices. Mobile applications are typically delivered to devices using over-the-air provisioning services that allow a mobile phone to download and install software over a cellular network connection. Current techniques for automa

11. Influence of point variants of pattern recognition receptors in the susceptibility to human malaria / Influência de variantes de receptores de reconhecimento padrão na suscetibilidade à malária
Malaria is one of the major causes of disease and death worldwide, mainly of children. It is also the strongest known force for evolutionary selection in the recent history of the human genome. Besides environmental and parasite factors, host genetic factors play a major role in determining both susceptibility to malaria and the course of infection. Innate i

12. Comunicação e valores do masculino: a construção da identidade na relação entre corpo e moda
In the transition between the 20th to the 21st centuries the masculine values have passed by significant change that came upon their conditions of life reorganization.The fashion, as the media which allows us to comprehend and build the identity of these characters, has pushed us to investigate how clothing and specially the shirt plays a role in this transf
