The nonsporing anaerobes are commonly implicated as significant pathogens in human infections especially brain abscesses. Conventional laboratory diagnosis of anaerobes is time-consuming. Rapid detection of anaerobes from the clinical specimens is the need of the hour. Direct Gas Liquid Chromatography (GLC) has been reported to be useful in rapid detection of anaerobes from the clinical specime...

The objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. To simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. Transition from the gas field to the liqui...

Dosulepin and doxepin are tricyclic antidepressants. The molecular geometries, harmonic vibrational frequencies, quantum chemical parameters and thermodynamic properties of dosulepin and doxepin were calculated by Generalized Gradient Approximation methods developed by Perdew and Wang (GGA-PW91) and Becke-Lee-Yang-Parr (GGA-BLYP) in the gas phase and solution media. The local reactivity of thes...

The 125I-radioimmunoassay for methaqualone in human urine was evaluated by a comparison with newly modified gas-liquid chromatographic and thin-layer chromatographic methods. The statistically significant sensitivity value for the radioimmunoassay was at 2 microgram of methaqualone per liter of urine. The coefficient of variation was 2.88 +/- 0.39% interassay and 2.71 +/- 0.16% intraassay. Ther...

A method for routine preparation of a solution of 133 Xe gas in saline from commercially available m Xe gas ampoules is described and evaluated. At room temperature and atmospheric pressure, about 25% of the mxe gas dissolves in saline. Xenon-133 binds to the syringe wall or may escape into the air when stored in sealed plastic syringes. Preparation immediately prior to use, short-term storage ...

The gas-phase structure of the conjugate base of p-hydroxybenzoic acid (and related compounds) and the influence of the solvent used in its generation by electrospray ionization have recently been under debate. While the phenoxide structure is known to be lower in energy in the gas phase, the carboxylate structure is favored in aqueous solution, fuelling the controversy. Here we probe the struc...

in this study, gas evolution in a vertical electrochemical cell is investigated numerically with a modified two-fluid model. the mathematical model involves solution of separate transport equation for the gas and liquid phases with an allowance to inter-phase transfer of mass and momentum. the governing equations are discreted via the finite volume technique and then are solved by the simple al...

for technical and economic success of miscible gas injection projects, an accurate laboratory measurement of minimum miscibility pressure (mmp) at reservoir conditions is essential. on the other hand, compositional reservoir simulator is a useful tool in gas injection studies and prediction of mmp. the main goal of this paper is to describe a procedure to generate a three phase sequential type ...
