3. Using Gold Nanoparticles as Passive Sampler for Indoor Monitoring of Gaseous Elemental Mercury
This study reports a functional passive sampler for monitoring gaseous elemental mercury (GEM). The material consists of gold nanoparticles (AuNP) deposited forming a film on thiol-modified glass slides. AuNP colloid was synthesized using sodium citrate, resulting in a size of 24.2 ± 0.8 nm, as determined by transmission electron microscopy analysis. For th

4. A Stochastic Reliability Model for Application in a Multidisciplinary Optimization of a Low Pressure Turbine Blade Made of Titanium Aluminide
Abstract Currently, there are a lot of research activities dealing with gamma titanium aluminide (γ-TiAl) alloys as new materials for low pressure turbine (LPT) blades. Even though the scatter in mechanical properties of such intermetallic alloys is more distinctive as in conventional metallic alloys, stochastic investigations on γ -TiAl alloys are very ra

5. Analysis of flicker level on the integration of fixed speed wind generators using multidiscipline models / Análise dos níveis de flicker na integração de geradores eólicos de velocidade fixa em redes de distribuição de energia elétrica utilizando modelos multidisciplinares
The discussions about the environmental issues and the need for renewable sources of energy, with low environmental impacts, mainly about CO 2 emission, have encouraged the Wind Energy expansion. The support for wind energy in the last decades enabled the improvement of the technology and a representative share in the electrical systems of some countries. Th

7. Chelated minerals for poultry
Organic minerals have been subject of an increasing number of investigations recently. These compounds can be considered the most significant event regarding commercial forms of minerals targeting animal supplementation in the last decades. Minerals, especially metals, are usually supplemented in poultry feeds using cheap saline sources and have never requir

8. Ontogenia craniana comparada de Arctocephalus australis, Callorhinus ursinus e Otaria byronia (Otariidae: Pinnipedia)
The search for mechanisms that can generate major morphological changes has led to the study of ontogeny, in part because some kinds of modifications of ontogenies seem an excelent way to generate major phenotypic change. We focus here on Arctocephlaus australis, Callorhinus ursinus and Otaria byronia with the aim of contributing to the understanding of the

9. Percurso da ação pública nas áreas informais do município de São Paulo: urbanização de favelas, mutirão e autoconstrução - 1979 - 1994 / The public action way in the homes built on the same urban and informal groundplot in São Paulo city: the intervencion in slums and the homes alternative production, by the community help and building by self help - between 1979 and 1994
The meaning objective of this work is to value the public action way in the homes built on the same urban and informal groundplot in São Paulo city, including the intervencion in slums and the homes alternative production, by the community help and building by self help, between 1979 and 1994. This period referes to the existence of the Fundo de Atendimento

11. Caracterização fenotípica e produção de biopolímeros por bactérias isoladas de nódulos de guandu [(Cajanus cajan (L.) Millsp.]. 2009, 166f. / Phenotypic characterization and biopolymers production by bacteria isolated from pigeonpea [Cajanus cajan (L.) Millsp.] root nodules. Seropédica: UFRRJ, 2008. 166p.
The biological nitrogen fixation (BNF) is a natural process carried out by prokaryotes collectively called diazotrophs. Among the diverse microorganisms able to fix the atmospheric nitrogen, stand out those capable of set up mutualistic associations with legume plants in specialized structures called nodules. Thus the search for microorganisms able to establ
