Hydrological studies were made for 6 months covering monsoon, summer and transition periods in a reservoir, chiefly to understand the plankton productivity. The physical factors like temperature, light, pH and chemical factors like dissolved O , CO , carbonate, bicarbonate, chloride, nitrate, phosphate, sulphate, calcium, 2 2 magnesium, sodium and potassium were estimated.

In the current study, the qualitative status of potable well water was assessed using the groundwater quality index during a course of 4 years (2014-2017). This study was carried out with an aim to monitor the drinking water resources from 12 potable wells on the multivariate analysis basis and for determination of groundwater quality index, the following 13 physicochemical parameters including...

A simple, specific and accurate reverse phase liquid chromatographic method was developed for the simultaneous determination of losartan potassium and ramipril in table dosage forms. A hypersil ODS C18, 4.6x250 mm, 5 mum column in isocratic mode, with mobile phase acetonitrile:methanol:10 mM tetra butyl ammonium hydrogen sulphate in water in the ratio of 30:30:40% v/v/v was used. The flow rate ...

Pathogenesis of pulmonary hypertension includes vascular smooth muscle cell membrane depolarisation and consequent calcium influx. Usually, calcium-gated potassium channels are activated under such conditions and repolarise the membrane. However, in pulmonary hypertension they are downregulated. The authors hypothesised that pharmacological augmentation of these channels would reduce pulmonary ...

An alkalophilic bacterium, Bacillus cereus produced an extracellular alkaline protease, which was found to be active at high temperature and pH range, suitable for commercial laundry detergents. B. cereus protease was partitioned in different aqueous two-phase systems such as PEG/dextran, PEG/potassium phosphate, PEG/sodium citrate, PEG/magnesium sulphate and PEG/sodium dihydrogen phosphate and...

. The kinetics of the reaction between potassium persulphate and potassium iodide has been studied iodometrically in aqueous solutions of sodium dodecyl sulphate (SDS) at various surfactant concentrations. It is observed that from low concentrations up to the c.m.c, the surfactant behaves like a normal electrolyte exhibiting primary kinetic salt effect. In presence of micelles it is observed th...
