Theoretical investigations on the laser isotope separation of Yb for medical applications.

The possibility of laser isotope separation of Yb from irradiated natural Yb has been investigated. The optimum process parameters such as powers and bandwidths of the lasers, Doppler broadening and the number density of the atoms have been derived through density matrix calculations. It has been shown that it is possible to produce Yb (>42% enriched) at a production rate of 62 μg/hour (or 1.

Lower-body muscular power predicts performance on urban combat simulation.

Background: Military operations in urban environments requires faster movements and therefore may place greater demands on soldier strength and anaerobic ability.

Objective: The aim was to study how physical fitness and body composition are associated with occupational test for urban combat soldiers before and after a 5-day military field exercise (MFE).

Methods: Twenty-six conscripts (age = 20±1 yrs.

Numerical study of the laser isotope separation of optically pumped Pd.

The feasibility of laser isotope separation of Pd through pulsed laser optical pumping followed by isotope selective photoionization has been studied through density matrix formalism. The effect of various parameters such as bandwidth of the excitation lasers, intensity of the lasers and Doppler broadening of the atomic ensemble on the efficiency of optical pumping and isotope selective photoionization have been evaluated. The optimum number density in the laser-atom interaction region has been derived from the studies of the effect of charge exchange collisions on the degree of enrichment.

Green synthesis, characterization and biological activities of silver nanoparticles synthesized from .

Background And Purpose: Metal nanoparticles are essential due to their unique catalytic, electrical, magnetic, and optical characteristics, as well as their prospective use in sensing, catalysis, and biological research. In recent years, researchers have focused on developing cost-effective and eco-friendly biogenic practices using the green synthesis of metal nanoparticles (AgNP).

Experimental Approach: In the present study, the aqueous extracts prepared from the leaf, stem, bark, and flower of were used for the synthesis of silver nanoparticles.

Formulation and evaluation of a novel herbal trio gel containing flax seed extract, carbopol and carboxymethyl cellulose.

It is of interest to formulate and evaluate herbal trio gel containing brown flax seed extract, carbopol, and carboxymethyl cellulose and to assess the antimicrobial, anti-inflammatory activity along with quality analysis using SEM and FTIR. The brown flax seeds were grinded into a fine powder and supercritical fluid was prepared which was mixed with CMC and carbopol. The formulation was checked for antimicrobial, anti-inflammatory activity, surface characteristics with SEM and FTIR.
