Investigação da imunomodulação por subpopulações de linfócitos na Leishmaniose ...
Peixoto, Rephany FonsecaLeishmaniasis is characterized as a complex of infectious-parasitic diseases caused by protozoa of the genus Leishmania. These diseases are present in 98 countries, where about 350 million people are at risk of infection. Visceral leishmaniasis (VL) is the most severe clinical form of the disease and induces immune responses mediated by distinct cell subpopulations, including invariant natural killer T cells (i...
Avaliação de Cursos a partir do Sinaes: uma contribuição à Comissão Própria de ...
Ribeiro, Wagner LeiteThe main objective of this study is to analyze the information contained in the course evaluation reports, made available to the academic community and to the society, on the website of the Evaluation Committee (CPA) of the Federal University of Paraíba (UFPB). National System for the Evaluation of Higher Education (SINAES), in order to assist the CPA/UFPB in the orientations given to the coordination of course...
Políticas públicas de educação e informação para inclusão e acessibilidade: est...
Pereira, Rodrigo Araújo de SáThis research deals with a study on the application of public policies of education and information for people with disabilities. It seeks to clarify the following question: How has the library of the Instituto Federal de Educação, Ciência e Tecnologia da Paraíba - Campus Cabedelo been acting with the execution of policies, programs, projects and general public practices of education for people with disabilitie...
Defeitos topológicos em teoria de campos com dinâmica generalizada
Souza, Igor AndradeThe purpose of this dissertation is to obtain defects solutions in Field Theory. Topological defects are localized solutions with finite energy. We begin the discussion formodels with one real scalar field with standard lagragian in (1+1) spacetime dimensions. We generalize this formalism to obtain field equations for models with no standard dynamics. Solutions of generalized models are called k-defects and are di...
Efeitos das dimensões extras em sistemas atômicos e o problema do raio do próton
Lêmos, Adiel da SilvaUnification theories that include gravitation, such as the Kaluza-Klein theory and string theory, predict the existence of the supplementary space. Motivated by large extra dimensions theory, we explicitly examined the influence of the postulates extradimensionality of spacetime on atomic systems where the usual four-dimensional gravitational effects are negligible. Initially, we present a complementary method to...
Oscilador harmônico num meio elástico com uma deslocação espiral
Maia, Anderson Vinícius Dantas MarquesIn this work, it is analysed the spectrum of energy of a spinless quantum particle subject to a two-dimensional harmonic oscillator in an elastic medium that possesses a spiral dislocation (a linear topological defect). It is also analysed the efects of this topological defect on the confinement to a hard-wall confining potential. Based on the diferential geometry, the information about the topological defect i...
Alguns resultados acerca de campos escalares em buracos negros, cosmologia quân...
Vieira, Horácio SantanaWe consider charged massive scalar fields in the gravitational and electromagnetic fields produced by different kinds of black holes, namely, the ones with and without a cosmic string, surrounded by a magnetic field, and in the f(R) theory of gravity. The special cases of massless and uncharged particles are also examined. Exact solutions of both angular and radial parts of the covariant Klein-Gordon equation in th...
Kinks e compactons em teoria de campos a temperatura finita e branas
Lima, Elisama Eraldene MarquesIn the present thesis, we study several models in field theory that support localized solutions. We present general properties of classical scalar field theory, highlighting some relevant models in the literature. From this, we use the deformation method to construct two new families of hyperbolic potencials, where several aspests were analysed. We also investigate models that develop dynamics of Dirac- Born- I...
Sistemática e filogenia do gênero Cyphoderus (Collembola, Paronellidae, Cyphode...
Oliveira, João Victor Lemos Cavalcante deThe genus Cyphoderus, distributed worldwide, was proposed by Nicolet for Entomobryomorpha without eyes, white or yellowish, with the fourth abdominal segment more than 3 times the length of the third, with scales in the body, smooth dens with piniform scales, antennal segments without subdivisions, unguis with 2 well developed basal teeth, unguiculum with a broad basal tooth. This genus has problems of classifi...
Autoecologia comparativa de duas espécies de quelônios (Phrynops geoffroanus e ...
Santana, Daniel OliveiraThe present study had as main objectives to evaluate how populations of Phrynops geoffroanus and Mesoclemmys tuberculata from Caatinga and Atlantic forest areas use the spatial, temporal and trophic resources available in the environment, as well as the influence of environmental conditions such as different rain regimes And availability of food resources, in the diet, reproduction, parasitism, population struc...
