Cephalosporin C (CPC), a β-lactam antibiotic, is starting molecule for industrial production of semi synthetic cephalosporins. CPC fermentation has been carried out in Air Lift Reactor (indigenously made up of borosilicate glass) in different fermentation modes i.e., batch and fed batch modes using a mold Acremonium chrysogenum (synn. Cephalosporium acremonium). A definite correlation exists be...

Gross Job Flows in Russian Industry Before and After Reforms: Has Destruction Become More Creative This paper uses 1985-1999 manufacturing census data for old Russian enterprises to calculate the magnitude and productivity effects of gross job flow rates before and after reforms. Job creation was low throughout the period in this sector, but increased slightly during the transition, while job d...

This paper provides evidence on job flows and worker flows at the level of the employer. We ask whether firms grow by increasing hires, reducing separations, or both, and we develop a graphical approach to address this. We use a new dataset to estimate the relationship between job flows and worker flows at the employer level. We show that most employers are simultaneously hiring and facing sepa...

The effects of ultrasonication of corn slurry, on particle size distribution and enzymatic hydrolysis was studied for the dry-grind mill ethanol industry. Two independent ultrasonic experiments were conducted at a frequency of 20 kHz; in batch and continuous systems. The ground corn slurry (33% m/v) was pumped at flow rates 10-28 L/min in continuous flow experiments, and sonicated at constant a...

A novel polymeric monolith with hydrophilic interaction and strong anion-exchange mixed-mode has been fabricated for pressurized capillary electrochromatography by an in situ copolymerization of vinylbenzyl trimethylammonium chloride (VBTA) and bisphenol A glycerolate dimethacrylate (BisGMA). The optimization of the polymerization mixture composition has been investigated, and column characteri...
