Ethyl benzene used increasingly each year is the raw material of producing styrene monomer. This substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. In this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...

INTRODUCTION Given the increase in hookah use among young adults, characteristics of hookah use/users, as well as reasons for its use or discontinuation among young adults, are critical to understand. METHODS Data from a study of 18–25 year olds from seven Georgia colleges/universities (n=2865) were analyzed to examined: 1) differences in socio-demographics and other substance use among current...

The front cover picture was designed by C. Zippel, Z. Hassan and S. Bräse. Kinetic resolution of 4-acetyl[2.2] paracyclophane via ruthenium-catalyzed enantioselective hydrogenation has been realized. This method can be performed on a multigram-scale gives access to enantiomerically pure derivatives with planar central chirality (Rp)-4-acetyl-PCP (97% ee, 43%) (Sp,S)-PCP 46%), which are useful i...

production of thermostable alkaline protease in tray bioreactor for solid state fermentation is a unique process which may lead to an economical approach for production of enzyme from agricultural waste or low cost substrate. in solid state fermentation using tray bioreactor, several agricultural residues such as rice bran, sugarcane bagasse, wheat bran, barely bran, corn meal and corn husk wer...
