Two-dimensional description of absorption in humans after dermal exposure to volatile organic compounds
(TAYLOR & FRANCIS INC, 2017-06-03)
A two-dimensional diffusion model was developed to predict the absorption of chemicals in humans following dermal contact. A firstorder evaporation rate equation was applied to the skin surface while a perfect-sink boundary ...
A Generalized Integral Method for Solving the Design Equations of Dissolution-Diffusion Controlled Drug Release from Planar, Cylindrical and Spherical Matrix Devices
(Elsevier Science, 2007-04)
A versatile approach for solving the design equations of dissolution/diffusion-controlled drug release from planar, cylindrical and spherical matrix systems is provided, as an extension of a previously validated approach ...

Lixiviación del Cs-137 en matrices cementadas
(Instituto Peruano de Energía NuclearPE, 2008-11)
The leaching rate of Cs-137 from the chemical treatment process in cement matrix has been studied. The solidification matrix was a standard Portland cement mixed with 5–10% of bentonite clay. The cement specimens were ...
Micro-shear bond strength of adhesives with different degrees of acidity: Effect on sound and artificially hypermineralized dentin
(2020-04-01)
This study evaluates the bond strength of four self-etching adhesive systems with different acidity levels in normal and artificially hypermineralized dentin substrate. Healthy human molars were divided into groups: normal ...
Evaluación de materiales adsorbentes en la remoción de ácido sulfhídrico presente en biogás producido en una granja porcícola
(Universidad de los AndesIngeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química, 2019)
El presente estudio muestra el planteamiento y evaluación de distintas matrices de adsorción, para la remoción de H2S de una corriente de biogás, que viene de un biodigestor implementado en una granja porcícola, para ...
Complex modal analysis of a vertical rotor through finite element method
(2012)
Natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical and complex modal analysis. The mathematical modeling was based ...
Testing the retention of attachments for implant overdentures - validation of an original force measurement system
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
P>The aim of this study was to validate an original portable device to measure attachment retention of implant overdentures both in the lab and in clinical settings. The device was built with a digital force measurement ...
Complex modal analysis of a slender vertical rotor by finite elements method
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2012-01-01)
In this paper, natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical modal and complex analysis. The equation that ...
Controlling the generation of bilayer and multilayer vesicles in block copolymer/epoxy blends by a slow photopolymerization process
(Royal Society of Chemistry, 2017-09)
Vesicles are a highly attractive morphology to achieve in micellar dispersions of block copolymers (BCP) in epoxy thermosets due to the fact that small amounts can affect a large volume fraction of the matrix, a fact that ...
