AIM The study evaluates the microbial as well as physicochemical pollution of groundwater of Brij region of Uttar Pradesh, a major tourist destination in the country along with estimating the drug resistance evident in the isolated Escherichia coli. MATERIALS AND METHODS A total of 60 samples of groundwater were collected from six different sites and assessed for physicochemical (pH, color, t...

A systematic experimental study of the effect of several factors on the mean drop diameter, d32, during emulsification, is performed with soybean oil-in-water emulsions. These factors are (1) type of used emulsifier; (2) emulsifier concentration, CS; and (3) ionic strength of the aqueous solution. Three different types of emulsifier, anionic (sodium dodecyl sulfate, SDS), nonionic (polyoxyethyl...

The anti-apoptotic B-cell CLL/lymphoma-2 (Bcl-2) protein and its counterpart, the pro-apoptotic Bcl-2-associated X protein (Bax), are key players in the regulation of the mitochondrial pathway of apoptosis. However, how they interact at the mitochondrial outer membrane (MOM) and there determine whether the cell will live or be sentenced to death remains unknown. Competing models have been prese...

By combining the experimental small- and wide-angle x-ray scattering (SWAXS) method with molecular dynamics simulations theoretical ‘complemented-system approach’ it is possible to obtain detailed information about intra- inter-molecular structure of solvation hydration surfactant in organic mixed solvents, e.g., nonionic Brij 35 (C12E23) alcohols aqueous alcohol-rich ternary systems. This firs...

Physico-chemical studies of some aqueous surfactant solutions were carried out by employing conductance, surface tension and spectrofluorometric techniques. From conductivity and surface tension measurements, critical micelle concentration (CMC), counter-ion association (α), equivalent conductance at infinite dilution (٨0), surface excess concentration (Γ), minimum area per molecule (Amin), sur...
