Development and validation of a method for the determination of folic acid in different pharmaceutical formulations using derivative spectrophotometry
Folic acid is a B complex water-soluble vitamin that is essential to humans, and its deficiency can cause problems including congenital malformations in the fetus as well as heart disease. Most countries affected by diseases ...
Evaluation of skin absorption of drugs from topical and transdermal formulations
(Univ Sao Paulo, Conjunto Quimicas, 2016-07-01)
The skin barrier function has been attributed to the stratum corneum and represents a major challenge in clinical practice pertaining to cutaneous administration of drugs. Despite this, a large number of bioactive compounds ...
The use of nonlinear programming as a tool for maximum profit feed formulation of broilers
The purpose of this study was to compare linear and nonlinear programming models for feed formulation, for maximum profit, considering the real variation in the prices of the corn, soybean meal and broilers during the ...
Controlled release formulations of herbicides based on micro-encapsulation
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2009)
Determination of atenolol in pharmaceutical formulations by diffuse reflectance spectroscopy
A simple analytical method for quantification of atenolol in pharmaceutical formulations by diffuse reflectance spectroscopy is described. The method is based on the reaction, on the filter paper surface, between the drug ...
Non-linear boundary element formulation applied to contact analysis using tangent operator
(ELSEVIER SCI LTD, 2011)
This work presents a non-linear boundary element formulation applied to analysis of contact problems. The boundary element method (BEM) is known as a robust and accurate numerical technique to handle this type of problem, ...
An analysis of formulations for the capacitated lot sizing problem with setup crossover
(Elsevier B.V., 2017-04-01)
The lot sizing problem with setup crossover is an extension of the standard big bucket capacitated lot sizing problem (CLSP). The general idea is that the first setup operation of each planning period can already start in ...
High-performance liquid chromatography determination of praziquantel in tablets and raw materials
A specific and sensitive high-performance liquid chromatographic method was developed for the assay of praziquantel in raw materials and tablets. It was also found that the excipients in the commercial tablet preparation ...
A computational comparison of 2 mathematical formulations to handle transmission network constraints in the unit commitment problem
Until recently, transmission network constraints have been incorporated into the unit commitment (UC) problem (security-constrained UC [SCUC]) using the classical direct current (DC)-based equation. This paper proposes a ...
