regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
Counterfeit medicines are a growing problem in both developing and industrialised countries. In general the evaluation of these medicines is limited to the identification and the dosage of the active ingredients. In this study in vitro dissolution tests were conducted on two sets of counterfeit medicines containing PDE-5 inhibitors (sildenafil citrate and tadalafil). The dissolution profiles we...
This study presents improvement in solubility and dissolution rate of valsartan (VAL) using β-cyclodextrin (βCD) and hydroxypropyl-β-cyclodextrin (HP-βCD). Formation and characterization of solid inclusion complexes were investigated by DSC, FTIR, SEM, HNMR and in-vitro dissolution studies. Preparation method influenced physical properties of binary mixtures. Inclusion complexes obtained by co-...

the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
The aim of this research project was to investigate a potential standardized test method to characterize the dissolution properties of numerous formulation types available for pulmonary delivery. A commercially available dissolution tester was adapted for use as a testing apparatus by the incorporation of a membrane-containing holder. The holder was designed to enclose previously air-classified...
A dissolution test for in vitro evaluation of tablet dosage forms containing 10 mg of rupatadine was developed and validated by RP-LC. A discriminatory dissolution method was established using apparatus paddle at a stirring rate of 50 rpm with 900 mL of deaerated 0.01 M hydrochloric acid. The proposed method was validated yielding acceptable results for the parameters evaluated, and was applied...
piroxicam (px), an anti-inflammatory drug, exhibits poor water solubility, dissolution and flow properties. thus, the aim of the present study was to improve the solubility and dissolution rate of px by freeze drying technique using dimethylformamide (dmf), chloroform and water as co-solvent system. the prepared crystals containing px were evaluated for dmf and chloroform solvent residual by ga...
