Rapid, precise, accurate, and specific ratiospectra derivative spectrophotometry and a simple UV spectrophotometry using simultaneous equation methods are developed for the simultaneous determination of bisoprolol fumarate and hydrochlorothiazide from combined pharmaceutical dosage forms. For ratiospectra derivative spectrophotometry, the amplitudes were measured at 202.6 nm for bisoprolol fuma...

in the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. analysis of the standard curve showed a linearity range for galactose from 2 mg/dl to 180 mg/dl with a regression equation of y = 0.013x ? 0.083; r² = 0.962. the advantage of the method is its ability to measure serum galactose quantitativ...

The textit{QIF}  (Quadrant Interlocking Factorization) method of Evans and Hatzopoulos solves linear equation systems using textit{WZ}  factorization. The  WZ factorization can be faster than the textit{LU} factorization  because,  it performs the simultaneous evaluation of two columns or two rows. Here, we present a  method for computing the real and integer textit{WZ} and  textit{ZW} factoriz...

A simple, specific, accurate and precise spectrophotometric method was developed validated for simultaneous estimation of Azelnidipine Valsartan in Synthetic Mixture. The wavelength 240.00 nm 250.00 nm. Beer’s law is obeyed the concentration range 2-10μg/ml 16-80μg/ml correlation coefficient 0.9999 0.9993 respectively. % recovery were found to be 101.2 - 101.9 101.8 Intraday precision 0.06 – 0....

A simple, specific, accurate and precise spectrophotometric method was developed validated for simultaneous estimation of Betamethasone Luliconazole in Synthetic Mixture. The wavelength 243.20 nm 225.00 nm. Beer’s law is obeyed the concentration range 10-50μg/ml 20-100μg/ml correlation coefficient 0.999 respectively. % recovery were found to be 100.49 & - 100.68 Intraday precision 0.10 %– 0...

We study the regularized, oscillatory, multiscale, quasilinear, elliptic problem in divergence form − div(Qη(x, x , u)∇u) = f, in Ω, (0.1) u = g, on ∂Ω, (0.2) assuming that the conductivity has the form Qη(x, y, r) = a−(x) + (a+(x)− a−(x))βη(r − ψ(x, y)), (0.3) for some domain Ω ⊂ Rn, n ≥ 1, a regularization βη of the Heaviside step function and a locally periodic function ψ(x, y), Y -periodic ...
