The present work search to analyze the behavior of the models of mensuration of market risk VaR and CVaR for in the Brazilian market of actions, calculated by the methodology of the historical simulation, GARCH, Riskmetrics and Normal. They were used as sample the data empiric of PETR4, TNLP4, VALE5, USIM5 and CSNA3, that understands the mail carrier of the Index of Bovespa five more liquid actions (Ibovespa) effective of January to April of 2006, with the closing prices embracing the period of 30/12/1998 to for 29/12/2005. All the methodologies were calculated for a α of 1% and 5%, using windows of 126 and 252 days. With the objective of testing the models the tests of Kupiec were used (unconditional), Christoffersen (conditional) and Berkowitz, and the test of Berkowitz was used for two cases, test of the tails of the distributions a...
Resumo da tese:Objectivos: Avaliou-se a adesão e a evolução temporal de Portugal ao padrão alimentar mediterrânico e às recomendações alimentares populacionais da World Health Organization (WHO) para a prevenção de doenças crónicas e degenerativas. Metodologia: Às disponibilidades de alimentos das balanças alimentares da Food and Agriculture Organization (FAO) relativas a Portugal no período entre 1961 e 2003, aplicaram-se dois índices de qualidade alimentar: o Mediterranean Adequacy Index (MAI) e o Healthy Diet Indicator revisto (HDIr). A correlação de Pearson foi utilizada para verificar a associação entre o MAI e outras variáveis contínuas como o tempo e as disponibilidades de grupos alimentares. A correlação de Spearman permitiu avaliar a relação entre o HDIr e a variável continua tempo. Resultados: Portugal aderiu ao padrão alimen...

Free-living amoebas are unicellular protozoan parasites found in humid soil and aquatic habitats. They develop in soil, dust, air and can also be isolated from motionless water, swimming pools, lakes, dams, contact lenses cleaning solutions, drains, air-conditioner, warming and ventilation units and intestinal lavage fluid. The genera of importance in Public Health are: Naegleria, Acanthamoeba, Balamuthia and Sappinia (recently discovered). Considering the Public Health impact of Acanthamoeba and Naegleria genera, a research was made to verify their existence in environmental samples (openair swimming pools and gardens) in Brasília, Brazil. Some samples from swimming pools (34) and soil (15) were collected in order to verify the presence of free-living amoebas. Direct observation of the samples previously concentrated and in vitro cult...
The thesis analyses exchange rate anchors over the 90´s and their relationship with economic fundaments. Specifically, it was examined whether the episodes of exchange rate volatility experienced in Brazil are directly caused by the deterioration of economic fundaments. First, the Real Plan was described, as well as the central role of the exchange rate anchor to that stabilization program. Next, from a theoretical standpoint, the definition and the uses of exchange rate anchors – in general –, along with the specifics of the Brazilian experience were evaluated. Next topic was the construction of an “exchange rate pressure index”, based on the nominal exchange rate, the stock of foreign exchange reserves and the current interest rates. The instrument was used to identify moments at which the national currency was under speculative atta...

Breast cancer is the most common cancer among women worldwide and is the first cause of mortality in Brazilian women. Early diagnostic is essential for the success in treatment. The tumor’s size and sentinel lymph node status are the main prognostic factors. This study used 44 patients with ductal invasive breast carcinoma submitted to a primary surgical treatment in HUB from 2007 to 2008. Our aim was evaluated the relation between VEGF and Bcl-2 expression in breast cancer by immunohistochemistry and the tumor’s size, lymph node status at the moment of histopathological diagnostic. In this study high VEGF expression wasn’t associated with tumor bigger than 2,0 cm and high Bcl-2 expression was strongly associated with the size of the tumor less than or equal to 2,0 cm. High VEGF expression was associated with neoplastic nodal involveme...
