This study aimed to characterize air pollution and the associated carcinogenic risks of polycyclic aromatic hydrocarbon (PAHs) at an urban site, to identify possible emission sources of PAHs using several statistical methodologies, and to analyze the influence of other air pollutants and meteorological variables on PAH concentrations.The air quality and meteorological data were collected in Oporto, the second l...

Traffic emissions and tobacco smoke are considered two main sources of polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor air. In this study, the impact of these sources on the level of fine particulate matter (PM2.5) and on the distribution of 15 PAHs regarded as priority pollutants by the US-EPA on PM2.5 were evaluated and compared. Outdoor and indoor PM2.5 samples were collected during winter 2008...
Introdução: O trabalho de equipa parece ser a lógica dominante das organizações de saúde com vista a aumentar a efectividade e melhorar os cuidados prestados ao doente. No entanto, a forma de estruturação das equipas e as componentes relacionais, dentro desta, parece ser, ainda, uma lacuna na literatura actual. Objectivos: Aprofundar os conhecimentos acerca do trabalho de equipa e a dinâmica das equipas cirúrgi...
A methodology based on microwave-assisted extraction (MAE) and LC with fluorescence detection (FLD) was investigated for the efficient determination of 15 polycyclic aromatic hydrocarbons (PAHs) regarded as priority pollutants by the US Environmental Protection Agency and dibenzo(a,l)pyrene in atmospheric particulate samples. PAHs were successfully extracted from real outdoor particulate matter (PM) samples wit...
Dissertação (mestrado)—Universidade de Brasília, Centro de Desenvolvimento Sustentável, 2008. ; Este trabalho apresenta uma análise do processo de constituição do Comitê da Bacia Hidrográfica do rio Paraguaçu - CBHP, quanto à composição dos seus membros, sua origem geográfica e o segmento representado, e sua influência na efetivação da gestão participativa dos recursos hídricos da bacia. Partindo-se da revis...
Although AIDS patients in other countries are frequently diagnosed as having atypical mycobacterial infection, in Southern Brazil there is a clinical impression that Mycobacterium tuberculosis is the rule rather than the exception. We made a retrospective review of cultures for mycobacteria at our hospital in order to determine the frequency of atypical mycobacteria and Mycobacterium tuberculosis in hospitalise...
