1. Construção da identidade dos jovens aprendizes : uma nova condição operária?
The investigation proposed by this dissertation has as its main interest to understand the relation that young apprentices have with their work. It seeked to analyze the professional identity constitution process of participating or egress youngsters from a professional qualification course, as a way of showing that access to work represents an important soc

2. Dark Energy and The Accelerating Universe: Conceptual Aspects and Observational Tests / Energia escura e aceleração do Universo: Aspectos conceituais e testes observacionais
In the last decade, the extraordinary progress of the astronomical observations (distances with supernovas, matter and cosmic background radiation (CBR) power spectrum, X-ray surface brightness of galaxy clusters, etc) associated with important theoretical developments turned Cosmology one of the most exciting frontiers of contemporary science. In this thesi

3. DYNAMIC BEHAVIOR OF BURIED PIPES: METHODOLOGY AND COMPUTATIONAL IMPLEMENTATION / COMPORTAMENTO DINÂMICO DE DUTOS ENTERRADOS: METODOLOGIA E IMPLEMENTAÇÃO COMPUTACIONAL
This work presents a numerical methodology for the analysis of buried pipes employed by the transport of oil and gas subject to dynamic loads. Emphasis is given to seismic loads. A finite element model based on a special class of beam element for the pipe representation is employed. Both geometric and material nonlinearities are considered in a total Lagrang

5. The cytosolic tail of class I MHC heavy chain is required for its dislocation by the human cytomegalovirus US2 and US11 gene products
The US2 and US11 glycoproteins of human cytomegalovirus facilitate destruction of MHC class I heavy chains by proteasomal proteolysis through acceleration of endoplasmic reticulum-to-cytosol dislocation. Modification of the class I heavy chain was used to probe the structural requirements for this sequence of reactions. The cytosolic domain of the class I he

6. Functional evidence for the mediation of diabetogenic T cell responses by HLA-A2.1 MHC class I molecules through transgenic expression in NOD mice
Particular major histocompatibility complex (MHC) class II alleles clearly contribute to T cell-mediated autoimmune type 1 diabetes (T1D) in both humans and nonobese diabetic (NOD) mice. However, studies in NOD mice indicate MHC class I-restricted T cell responses are also essential to T1D development. In humans, epidemiological studies have suggested that s

7. Gut injury in mouse graft-versus-host reaction. Study of its occurrence and mechanisms.
The occurrence, nature, and pathogenesis of intestinal lesions were studied in a number of graft vs. host reaction (GVHR) conditions in mice, combining variations in the nature of the following: the F1 hosts (newborn or adult, normal or lethally irradiated), the injected parental T cells (mixed or selected subsets of Lyt2+ or L3T4+ cells), and the antigenic

8. External blockade of the major cardiac delayed-rectifier K+ channel (Kv1.5) by polyunsaturated fatty acids.
The present work shows that arachidonic acid and some other long chain polyunsaturated fatty acids such as docosahexaenoic acid, which is abundant in fish oil, produce a direct open channel block of the major voltage-dependent K+ channel (Kv1.5) cloned in cardiac cells. The inhibitory action of these selected fatty acids is seen when they are applied extrace

9. The Yaa gene abrogates the major histocompatibility complex association of murine lupus in (NZB x BXSB)F1 hybrid mice.
To investigate the specific contribution of select MHC class II genes on the development of murine lupus, H-2 congenic (NZB x BXSB)F1 hybrid mice bearing either H-2b/b, H-2d/b, or H-2d/d haplotypes were generated. We compared the clinical development (autoantibody production and glomerulonephritis) of systemic lupus erythematosus (SLE) in these three F1 hybr

10. Biochemical evidence that MCF murine leukemia viruses are envelope (env) gene recombinants.
Recently, a novel class of murine type C virus (MCF), some strains of which are highly oncogenic in the AKR acceleration test, has been isolated from premalignant and malignant thymuses of AKR mice. The biology of these viruses suggested that MCFs are the product of recombination between endogenous ecotropic and xenotropic viruses and, further, that the reco

11. Identification of a Naturally Processed Cytotoxic CD8 T-Cell Epitope of Coxsackievirus B4, Presented by HLA-A2.1 and Located in the PEVKEK Region of the P2C Nonstructural Protein
The adaptive immune system generates CD8 cytotoxic T lymphocytes (CTLs) as a major component of the protective response against viruses. Knowledge regarding the nature of the peptide sequences presented by HLA class I molecules and recognized by CTLs is thus important for understanding host-pathogen interactions. In this study, we focused on identification o
