Tablets containing metoprolol succinate and Compritol(®) 888ATO in the ratio of 1:2 yielded the desired sustained release profile in phosphate buffer pH 6.8 when evaluated using USP type II paddle apparatus and was selected as the optimized formulation. Robustness of optimized formulation was assessed by studying the effect of factors like varying source of metoprolol succinate and Compritol(®)...

Rare earth oxides such as La2O3 and Gd2O3 are abundant in waste optical glass. The separation of rare is beneficial to the recycling resources. In this study, oxide particles were separated from using high gradient magnetic separation, influence different fluid media (i.e., water, anhydrous ethanol, their mixture) on results was investigated. By measured zeta potential water/ethanol pH water wi...

Objective: This study is planned to examine the possible beneficial effect of chronic administration of melatonin on ethanol drinking in rat models chronic voluntary ethanol consumption. Methods: Intermittent access 10% ethanol two-bottle-choice drinking paradigm was employed in 4 groups of rats where the rats had access to ethanol on alternate days in a week and a free access to water on all d...

A new fluorescent probe P derived from naphthalimide bearing a pyridine group has been synthesized and characterized. The proposed probe P shows high selectivity and sensitivity to Cu2+ in aqueous media. Under optimized conditions, the linear response of P (2 μM) toward Cu2+ was 0.05-0.9 μM in ethanol-water solution (3:2, v:v, 50 mM HEPES, pH 7.4), and the detection limit was 0.03 μM.

UNLABELLED Adequate polymerization plays an important role on the longevity of the composite resin restorations. OBJECTIVES The aim of this study was to evaluate the effect of light-curing units, curing mode techniques and storage media on sorption, solubility and biaxial flexural strength (BFS) of a composite resin. MATERIAL AND METHODS Two hundred and forty specimens were made of one comp...

In this theoretical study, we focus on a kind of danunarane sapogenins. This molecule optimized in venoussolvent media such as heptao, carbontetrachloride, toluene. tetrahydrofurane, dichloroethane, ethanol, methanol,dimethylsulfoxide and water using the self-consistent reaction field model. This process depends on either thereaction potential function of the solvent or charge transfer operator...

Energetic and structural results for ethanol-water mixtures as a function of the mole fraction were calculated using Monte Carlo methodology. Energy partitioning results obtained for equimolar water-ethanol mixture and ether organic liquids are compared. It has been shown that at xet=0.22 the RDFs for waterethanol and ethanol-ethanol interactions indicated strong hydrophobic interactions betwee...

Abstract In this study , palladium nano-particles were electro deposited galvano - statically on carbon black powder (Vulcan XC -72R). The catalytic activity for electro - oxidation of ethanol and methanol in alkaline media were studied by cyclic voltammetry and linear sweep voltammetry techniques. The results indicated that the electro-oxidation of ethanol and methanol strongly depends o...

the performance of selective media ltb, (leauryl tryptose broth), mmgm (minerals modified glutamate medium), bgbb (brilliant green bile broth), for the detection of e.coli in water in water, were compared and the following result were obtained: the mmgm found to be unsuitable as confirmatory medium for the detection of e.coli at 44 c, due to the occurrence of an unacceptable number of the false...
