Sistema de indicação de ajuste da constante K do cronotacógrafo eletrônico 1318
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2017-06-08)
The tachograph is a device used to register vehicle travel information. Out of all information available about the vehicle, it is possible to highlight, instant velocity, mean velocity, distance travelled and travel time. ...
Predictive QSPR study of the dissociation constants of diverse pharmaceutical compounds
(Wiley Blackwell Publishing, Inc, 2010-11)
The objective of the article was to perform a predictive analysis, based on quantitative structure-property relationships, of the dissociation constants (pKa) of different medicinal compounds (e.g., salicylic acid, salbutamol, ...
Validation of kinetic modeling of progesterone release from polymeric membranes
(Shenyang Pharmaceutical University, 2018-01)
Mathematical modeling in drug release systems is fundamental in development and optimization of these systems, since it allows to predict drug release rates and to elucidate the physical transport mechanisms involved. In ...
Application of the Potentiometric Stripping Analysis with Constant Current for the Determination of Lithium Ions Using a Spinel-Type Manganese (IV) Oxide-Modified Carbon Paste Electrode
(Bentham Science Publ Ltd, 2010-04-01)
A potentiometric stripping method for the measurement of lithium ions at a carbon paste electrode modified with spinel-type manganese oxide is described. The procedure is based on the effective pre-concentration of lithium ...
