the present investigation was aimed at studying the effect of incubation period, media, vitamins and solvents on biotransformation of albendazole by cunninghamella blakesleeana. the transformation was evaluated and identified by high performance liquid chromatography (hplc) and the structures of the transformed products were assigned by liquid chromatography-tandem mass spectrometry (lc/ms/ms) ...

the nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. as the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated aeromonas and the antibacterial effect of metal nanoparticles is well known for centuries, ...

An efficient technique for biotyping, using disposable trays instead of glass tubes and agar instead of liquid media, is described.

Recent experiments suggest that Bose-Einstein condensation (BEC) in liquid 4He can be localized when the liquid is confined in porous media. We demonstrate in a simple model of hard core bosons using Monte Carlo that the condensate can be separated into two parts. The two regions of condensate are separated by a region of uncondensed fluid that forms in response to a local attractive external p...

Porous media column experiments were used to investigate Pseudomonas fluorescens strain P17 transport as a function of water content and the influences of the solid–liquid and gas–liquid interfaces. Retention of radiolabeled P17 in washed quartz sand was evaluated at 100, 84, and 46% water saturation. At the completion of each experiment, the porous medium was extruded and sampled directly for ...

In this paper, an experimental-theoretical method is suggested for defining physical-mechanical characteristics of polymer materials with regard to influence of corrosive liquid media. Experimental dependences of mechanical characteristics on a swelling function are given for a series of polymer materials. One dimensional and three-dimensional linear-elastic models of body deformation with rega...

The objective of the study was to determine the most suitable cyst forming media in liquid conditions. Encystation in Azospirillum brasilense Cd was observed by using routine laboratory staining and microscopy. Best encystment occurred in liquid or semisolid media containing fructose (8 mM) and KNO3(0.5 mM). The encysted forms consisted of a central body filled with poly-β -hydroxybutyric acid ...

The dissipation of an elastic wave in dry and wet glass bead packings is measured using multiple sound scattering. The interplay of a linear viscoelastic loss and a nonlinear frictional one is observed in dry media. The Mindlin model provides a qualitative description of the experiment, but fails to quantitatively account for the data due to grain roughness. In weakly wet media, we find that th...
