(2021-01-01)
Vulvovaginal candidiasis is a public health problem with a high incidence among female patients. Currently, there is an increase in the identification of Candida spp. resistant to current therapy, making it necessary to ...
Chemometrics-assisted simultaneous voltammetric determination of ascorbic acid,uricacid,dopamine and nitrite: Application of non-bilinear voltammetric data for exploiting first-order advantage
(Elsevier Science, 2014-01)
For the first time, several multivariate calibration (MVC) models including partial least squares-1 (PLS-1), continuum power regression (CPR), multiple linear regression-successive projections algorithm (MLRSPA), robust ...
Simultaneous determination of dapsone and pyrimethamine by derivative spectrophotometry in pharmaceutical formulations
(AOAC INTERNATIONAL, 2003-03)
A simple and fast method was developed for the simultaneous determination of dapsone and pyrimethamine by first-order digital derivative spectrophotometry. Acetonitrile was used as a solvent to extract the drugs from the ...
Ecuaciones simultáneas: Determinación e indeterminación por método gráfico.
(2016-07-01)
The solution to a system of simultaneous equations is a great interest. However it is important to conceptualize and visualize before the involvement of simultaneity in the determination or indeterminacy of the system, ...
Simultaneous determination of ascorbic acid and acetylsalicylic acid in pharmaceutical formulations
(AOAC INTERNATIONAL, 2001-02)
A direct, simple, and practical first-derivative spectrophotometric method is described for simultaneous determination of ascorbic acid and acetylsalicylic acid. The effects of the solvent, excipients, and spectral variables ...
