1. Avaliação da concentração e composição inorgânica do material particulado coletado no estado do Rio de Janeiro
Cities urbanization and modernization increase emission sources, contributing to particulate matter (PM) composition heterogeneity and enhance the risk to human health and environment. This paper intends to survey the studies on particulate matter carried out in the state of Rio de Janeiro. The sampling of PM is generally made using Hi-Vol samplers to collec

2. Caracterização do material particulado em Cubatão / CHARACTERIZATION OF PARTICULATE MATTER IN CUBATÃO
This work evaluated the particulate matter (PM) collected at the Environmental Research and Training Center (CEPEMA) located in Cubatão City. Sampling was made between 2009, March and 2010, November for fine, coarse and inhalable aerosol (Mini-Vol) and for the various fractions of PM with a cascade impactor (MOUDI) during eight experimental campaigns. A cli

3. Desenvolvimento de espectroscopia de plasma induzido por laser para aplicações em análise de patrimônio cultural: estudo de moedas de Um Cruzeiro de 1945 e Mil Réis de 1939 / DEVELOPMENT OF LASER INDUCED BREAKDOWN SPECTROSCOPY OF ONE "CRUZEIRO" FROM 1945 AND THOUSAND "RE¶IS" FROM 1939 FOR APPLICATIONS ON CULTURAL HERITAGE ANALYSIS: STUDY OF COINS
In this work, the technique of laser induced breakdown spectroscopy was developed for application in cultural heritage analysis in order to study coins of one \Cruzeiro" from 1945 and a thousand \R¶eis" from 1939, using a Nd:YAG laser operating in Q-switched mode. It had been determined the best conditions of laser and detection features such as pulse energ

4. ProduÃÃo e estudo da microestrutura e propriedade mecÃnica da cerÃmica Ba2HoZrO5,5 a base de zircÃnia para fabricaÃÃo de cadinhos de alta temperatura
In view of the need of use of crucibles for sintering and crystal growth of advanced ceramics in high temperature furnaces, a study has been realized on a new complex cubic perovskite oxide ceramic Ba2HoZrO5,5 based on zirconium in the Ba-H-Zr-O system. Complex perovskites, which have generally A2BBâO6 or A3B2BâO9 type composition, result by ordering of B
