Molecular detection of in-vivo microbial contamination of metallic orthodontic brackets by checkerboard DNA-DNA hybridization
(Mosby-elsevier, 2012-01-01)
Introduction: Knowing the microbiota that colonizes orthodontic appliances is important for planning strategies and implementing specific preventive measures during treatment. The purpose of this clinical trial was to ...
Modelos de universo e equação de estado na cosmologia
(Universidade Estadual Paulista (Unesp), 2002-10)
Neste trabalho fazemos uma revisão do modelo cosmológico padrão, o modelo de Friedmann, e estudamos o modelo de universo de de Sitter, que é o paradigma de uma expansão acelerada para o fator de escala cósmico - fato que ...

(Universidade Estadual Paulista (Unesp), 2007-10-07)
Os estudos dos diferentes modelos de aglomerações produtivas, seja na forma de pólos, distritos, clusters ou APL´s (Arranjos Produtivos Locais) devem ser realizados a partir da análise estrutural de suas cadeias produtivas ...
Effect of Different Solvent Ratios (Water/Ethylene Glycol) on the Growth Process of CaMoO4 Crystals and Their Optical Properties
(Amer Chemical Soc, 2010-11-01)
In this paper, calcium molybdate (CaMoO4) crystals (meso- and nanoscale) were synthesized by the coprecipitation method using different solvent volume ratios (water/ethylene glycol). Subsequently, the obtained suspensions ...
In Situ and Simultaneous UV-vis/SAXS and UV-vis/XAFS Time-Resolved Monitoring of ZnO Quantum Dots Formation and Growth
(Amer Chemical Soc, 2011-03-24)
The processes of formation, aggregation, and growth of ZnO quantum dots (Qdot) induced by the addition of KOH solution ([OH]/[Zn] = 0.5) to the zinc oxy-acetate ethanolic solution at 40 degrees C were examined in depth by ...
Developing a research agenda for promoting physical activity in Brazil through environmental and policy change
(Pan Amer Health Organization, 2012-08-01)
Objective. To identify the highest priorities for research on environmental and policy changes for promoting physical activity (PA) in Brazil; to uncover any gaps between researchers' and practitioners' priorities; and to ...
Structure and optical properties of [Ba1-xY2x/3](Zr0.25Ti0.75)O-3 powders
(Elsevier B.V., 2010-07-01)
[Ba1-xY2x/3](Zr0.25Ti0.75)O-3 powders with different yttrium concentrations (x = 0, 0.025 and 0.05) were prepared by solid state reaction. These powders were analyzed by X-ray diffraction (XRD). Fourier transform Raman ...
Intense and broad photoluminescence at room temperature in structurally disordered Ba[Zr0.25Ti0.75]O-3 powders: An experimental/theoretical correlation
(Pergamon-Elsevier B.V. Ltd, 2008-07-01)
Intense and broad photoluminescence (PL) emission at room temperature was observed on structurally disordered Ba[Zr0.25Ti0.75]O-3 (BZT) powders synthesized by the polymeric precursor method. BZT powders were annealed at ...
