Transferênce de metais pesados, flúor e radionuclídeos para solos agrícolas na bacia do rio Corumbataí (SP)
(2005-12-01)
The use of phosphate fertilizers and amendments in sugar cane crops may increase the concentration of some elements in soils, from where they would become available for plants (principally in acid soils) and transferred ...
Glass structure and ion dynamics of lead-cadmium fluorgermanate glasses
(American Institute of Physics (AIP), 2004-05-22)
Glass structure and fluorine motion dynamics are investigated in lead-cadmium fluorgermanate glasses by means of differential scanning calorimetry, Raman scattering, x-ray absorption (EXAFS), electrical conductivity (EC), ...
Contribuição ao estudo da interrelação flúor-manganês em ratos
(Universidade de São Paulo (USP), Escola Superior de Agricultura, 1980-01-01)
Devido a numerosas discrepâncias nos resultados de estudos experimentais relativos à interação flúor-manganês, propusemo-nos a verificar se a adição de manganês 5 água fluoretada (1 ppm), em diferentes proporções fluor-manganês, ...

(2013-10-01)
Cytotoxicity and subcutaneous tissue reaction of innovative blends composed by polyvinylidene fluoride and polyvinylidene fluoride-trifluoroethylene associated with natural polymers (natural rubber and native starch) forming ...
Teor de flúor na água de poços superficiais
(Universidade Federal de Uberlândia (UFU), 2012-05-01)
Most of the water supplies in Brasil have a low Fluoride concentration, however there are some places where these concentrations are above the recommended as suitable for human consumption, causing chronicle intoxication, ...
The influence of residual salivary fluoride from dentifrice on enamel erosion: An in situ study
(2008-01-01)
The objective of this study was to assess the salivary residual effect of fluoride dentifrice on human enamel subjected to an erosive challenge. This crossover in situ study was performed in two phases (A and B), involving ...
Thermal analysis of conductive blends of PVDF and poly(o-methoxyaniline)
(2000-11-01)
The thermal behavior of blends of poly(vinylidene fluoride), or PVDF, and poly(o-methoxyaniline) doped with toluene sulfonic acid was studied by thermogravimetic analysis, electrical conductivity measurements, differential ...
