New room temperature coacervation scheme for lead traces determination by solid surface fluorescence. Application to wines produced in Argentina
(Elsevier, 2015-07)
Lead traces were preconcentrated on paper filter discs using the coacervation phenomenon based on cationic and anionic surfactant reaction at room temperature. The increase in fluorescent signal of Rhodamine B dye was used ...
Impact of Redox Cycles on Manganese, Iron, Cobalt, and Lead in Nodules
(John Wiley & Sons Ltd, 2020)
Trace metal concentrations and body condition in adult Adélie penguins (Pygoscelis adeliae) from the western Antarctic Peninsula
(Pontificia Universidad Católica de Valparaíso, 2020)
Simulated high frequency ray paths considering traveling ionospheric disturbances
(SN Applied Sciences, 2020-03)
This study presents a modified version of a classical 3-D numerical ray tracing code [originally by Jones and Stephenson (A versatile three-dimensional ray tracing computer program for radio waves in the ionosphere. Office ...
Neoicnologia como ferramenta para interpretação de traços fósseis da Icnofauna de aracnídeos da formação Botucatu (cretáceo inferior, bacia do Paraná)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2016-05-12)
Ichnofossils are abundant in the sandstones of the Botucatu Formation,
Paraná Basin, of Neocomian age. This formation covers much of the Midwest,
Southeast and South of Brazil, and other countries in South America. ...
Essential Nutrient and Trace Element Foliar Resorption of Two Co-Existing Nothofagus Species Grown Under Different Environmental Conditions in Southern Patagonia
(Frontiers Media, 2019-11)
Nutrient resorption is crucial for mineral element conservation and efficiency of forest species, but knowledge on its significance and the mechanisms involved is still limited for most species and habitats. Focusing on ...
Investigating the Binding Heterogeneity of Trace Metal Cations With SiO2 Nanoparticles Using Full Wave Analysis of Stripping Chronopotentiometry at Scanned Deposition Potential
(2020-12-16)
Silica oxides nano- and microparticles, as well as silica-based materials, are very abundant in nature and industrial processes. Trace metal cation binding with these bulk materials is generally not considered significant ...
Cephalometric analysis of prediction tracings: A comparison of three different methods
(2013-06-01)
The purpose of this study was to compare-using cephalometric analysis (McNamara, and Legan and Burstone)-prediction tracings performed using three different methods, that is, manual and using the Dentofacial Planner Plus ...
