1. Vectorial capacity, basic reproduction number, force of infection and all that: formal notation to complete and adjust their classical concepts and equations
A dimensional analysis of the classical equations related to the dynamics of vector-borne infections is presented. It is provided a formal notation to complete the expressions for the Ross' Threshold Theorem, the Macdonald's basic reproduction "rate" and sporozoite "rate", Garret-Jones' vectorial capacity and Dietz-Molineaux-Thomas' force of infection. The a

2. The TP53 fertility network
The TP53 gene, first described in 1979, was identified as a tumor suppressor gene in 1989, when it became clear that its product, the p53 nuclear phosphoprotein, was frequently inactivated in many different forms of cancers. Nicknamed "guardian of the genome", TP53 occupies a central node in stress response networks. The p53 protein has a key role as transcr

3. Trabalho, educação e a atual política de formação docente no Brasil: uma análise à luz da crítica marxista. / Work, education and the current policy of teacher education in Brazil: a review in light of the Marxist critique.
This dissertation evaluates the ontological relation involving work, education and current policies for the formation of elementary school teachers. It is the upshot of a bibliographic research whose focus was the works of Marx, Engels, Lúkács, Mészáros, among other, in association with analysis of several documents dealing with current policies directed

4. Modelagem e controle de propagação de epidemias usando autômatos celulares e teoria de jogos. / Modelling and control of disease propagation using cellular automata and game theory.
Estuda-se o espalhamento de doenças contagiosas utilizando modelos suscetível-infectado-recuperado (SIR) representados por equações diferenciais ordinárias (EDOs) e por autômatos celulares probabilistas (ACPs) conectados por redes aleatórias. Cada indivíduo (célula) do reticulado do ACP sofre a influência de outros, sendo que a probabilidade de oco

5. Modelagem matematica da Influenza A(H1N1) / Mathematical modeling of Influenza A(H1N1)
This study aims to model the Influenza A (H1N1). Using differential equations, and based on the biological aspects of the infectious process, we obtain a dynamic system. The evolution of the disease within a population, considered constant, was examined through the trivial and nontrivial equilibrium points of the system, and their stabilities. In this contex

6. Morphophunctional assessments of testis in adult coatis (Nasua nasua Linnaeus, 1766) / Avaliação morfofuncional do testículo de quatis (Nasua nasua, Linnaeus, 1766) adultos
The study of the testicular morphophysiology in wild animals has been increased in the last years, seeking the development of protocols in assisted reproduction, due the constants threats on the fauna with the crescent human development. On the other hand, some few species, like the procyonids coati (Nasua nasua), present great adaptability to adverse condit

7. Dynamics of the 2006/2007 dengue outbreak in Brazil
We analyzed dengue incidence in the period between October 2006-July 2007 of 146 cities around the country were Larval Index Rapid Assay (LIRA) surveillance was carried out in October 2006. Of these, we chosen 61 cities that had 500 or more cases reported during this period. We calculated the incidence coefficient, the force of infection (») and the basic r

8. Relação entre o índice de infestação predial (IIP), obtido pelo levantamento rápido (LIRAa) e intensidade de circulação do vírus do Dengue. / Relation between the House Index levels obtained from LIRAa and dynamics of dengue virus circulation.
The prime objective of this study is to verify the existence of a relation between the House Index levels obtained from LIRAa and dengue transmission during the weeks after the release of the former. It is based on an ecological study which rely on municipal analysis units obtained from SINAN as well as from records about LIRAa taken from 2003 to 2006, accor

9. EstimaÃÃo de ParÃmetros GenÃticos, FenotÃpicos e Ambientais para a Qualidade da Madeira de Eucalyptus em Ãrvores Vivas. / Estimation Of Genetic, Phenotypic And Environmental Parameters For Eucalyptus Wood Quality In Living Trees.
The evaluation of the technological characteristics of wood, in most times, is accomplished through destructive methods. But, that process make it impossible the evaluation of a large number of genetic materials. So, the utilization of non-destructive methods makes it possible to evaluate a large amount of trees, allowing a more intensive selection of trees

10. Modelagem matematica da dinamica da Leishmaniose / Mathematical modeling of dynamics of Leishmaniasis
We are dealing with a modelling of leishmaniasis considering initially the urban cycle with 2-hosts aiming to extend the results to a peridomestic cycle for n-hosts. In the urban case we consider the vector population constant, also, variable. We simplify the model the assess the factor regarded to risk of leishmaniasis analysis, which is the deforestation.

12. O budismo leigo da Soka Gakkai no Brasil : da revolução humana a utopia mundial
This dissertation analyzes the lay Buddhist movement Sôka Gakkai and its transplantation to Brazil. This movement wasfounded in the 1930s in Japan by a primary school teacher, Tsunesaburô Makiguchi (1871-1944), initially as a study group connected with Nichiren Shôshú ("Orthodox Sect of Nichiren Buddhism "). Excommunicated by this sect in 1991, Gakkai ma
