ment. And, for the first few years, Darjeeling did make some sort of start. Houses were built, a few retired officers made their way to it, a depot for Military invalids was opened, and ? one or two Civilians and Merchants sent their families to the place. But it became evident after a time, that Darjeeling had not achieved popularity. The station increased very slowly; such institutions as are...

Trimetazidine dihydrochloride, a cellular antiischemic agent indicated in the management and prophylaxis of angina pectoris is given as 20 mg thrice daily in the conventional dosage regimen. The purpose of the present study was to formulate and evaluate twice a day extended release tablets containing 30 mg trimetazidine dihydrochloride. The method developed to formulate these extended release t...

Abstract The main aim of this study was to prepare and evaluate the extended - release system of an anxiolytic substance. Alprazolam is a short-acting benzodiazepine with general properties similar to those of diazepam. Our studies focused on the development of extended drug delivery system based on Hydroxy Propyl Methyl Cellulose (HPMC 4000cps) as retard agent and polyvinylpyrrolidone (PVP k30...

Extended-release matrix tablets of diltiazem hydrochloride (DTZ) were prepared using waxy materials alone or in combination with Kollidon SR. Matrix waxy materials were carnauba wax (CW), bees wax (BW), cetyl alcohol (CA) and glyceryl monostearate (GMS). Dissolution studies were carried out by using a six stations USP XXII type 1 apparatus. The in vitro drug release study was done in 1000 ml ph...

2014 The polymorphism of a new series 4-[-4"-alkoxy-cinnamoyloxy] benzylidene-4’-cyanoaniline was studied and a re-entrant nematic phase was observed for the three homologues n = 8, 9, 10. The decyloxy compound exhibits the unusual N SA SC Nre sequence. For the first time, phase diagrams connected with X-ray analysis confirm this result. The partial bilayer SC notion is introduced. J. Physique ...

Magnetoelectric force microscopy (MeFM) is characterized as methodical tool for the investigation of antiferromagnetic domain states, in particular of the 180 ∘ variety. As reference compound for this investigation we use Cr 2 O 3 . Access to the antiferromagnetic order is provided by the linear magnetoelectric effect. We resolve the opposite antiferromagnetic 180 ∘ domain states of Cr 2 O 3 an...
