Simple, accurate and precise ultraviolet spectrophotometric and reversed-phase high-performance liquid chromatographic (RP-HPLC) methods for simultaneous estimation of amlodipine besylate (AMLO) and olmesartan medoxomil (OLME) in combined tablet dosage form have been developed and validated. Beer’s law was obeyed in the concentration range of 5-70 and 5-60 μg/mL in methanol at 238 nm and 257 nm...

Two simple, accurate and precise methods for simultaneous estimation of Esomeprazole and Itopride in bulk drug and tablet dosage form have been described. Method-A employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. Method -B is Absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.Beer’s law was obeyed in the con...

today one of the major questions in the iranian economy is that do liquidity injected into the economy more effected productive activities or speculative activities .this study was conducted to compare the effects of liquidity growth on real sector and assets market bubbles in iranian economy during the period 1994(2)-2012(1). for this purpose, price index of four major assets in iranian econom...

We consider the oxygen diffusion equation. Oxygen diffusion in a sike cell with simultaneous absorption is an important problem. Oxygen diffusion has a wide range of medical applications. Numerical solutions of its partial differential equation are obtained by extrapolation method with the vector of values V approximating to C (diffusion) at the mesh points. And the results gave a good agreemen...

Weconstruct finite difference discretizations of the acousticwave equation in complicated geometries and heterogeneous media. Particular emphasis is placed on the accurate treatment of interfaces at which the underlying media parameters have jump discontinuities. Discontinuousmedia is treated by subdividing the domain into blockswith continuousmedia. The equation on each block is then discretiz...

Simple, sensitive, and specific spectrophotometric methods were developed and validated for quantitation of diclofenac potassium and tizanidine in tablet dosage form. Three new analytical methods were developed based on the simultaneous estimation of drugs in a binary mixture without previous separation. In multiwavelength technique, the binary mixture was determined by mixed standards and thre...

We present a method for the computation of stable and unstable solutions of a discretized reaction-diiusion equation. Fixed point solvers are frequently used for this problem. But they diverge for many applications. A method for the stabilization of these solvers has been introduced in 3] and 6]. This (sequential) method is now modiied so that the algorithm allows for parallel execution. The pa...

For the purpose of computer calculation to evaluate time-dependent quantum properties in finite temperature, we propose new numerical method expressed in the forms of simultaneous differential equations. At first we derive the equation of motion in finite temperature, which is found to be same expression as Heisenberg equation of motion except for the c-number. Based on this equation, we constr...

in this paper, the solution of the evolutionaryfourth-order in space, sivashinsky equation is obtained by meansof homotopy perturbation method (textbf{hpm}). the results revealthat the method is very effective, convenient  and quite accurateto systems of nonlinear partial differential equations.
