a study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Formation of Ribosomes from Precursor Ribonucleoprotein Particles.
Sypherd, Paul S. (University of California, San Diego). Formation of ribosomes from precursor ribonucleoprotein particles. J. Bacteriol. 90:411-417. 1965.-Amino acid deprivation of a "relaxed" mutant leads to the accumulation of ribonucleoprotein particles. The possibility that these particles are equivalent to normal ribosome precursors was investigated. This was accomplished by determining th...
متن کاملPreparation mechanism and luminescence of Sr2SiO4:Eu phosphor from (Sr,Eu)CO3@SiO2 core-shell precursor
Sr2SiO4:Eu phosphor for white light emitting diodes (LEDs) was synthesized by employing an as-prepared (Sr,Eu)CO3@SiO2 core-shell precursor as starting materials, and the effect of the core-shell precursor was also discussed on the crystal structure, particle morphology and luminescent properties of the resultant phosphor. The results showed that the hybrid βand α′-Sr2SiO4: Eu phosphor with fin...
متن کاملThe formation of enterokinase from a precursor in the pancreas.
IN a recent paper [1932] the writer presented data upon the rate of formation of enterokinase from its precursor in the pancreas. It was found that the observed rate conforms to the unimolecular expression and that it is a function of the hydrogen ion concentration of the medium, exhibiting a maximum at about PH 6-90. Certain additional experiments which have been carried out are now described....
متن کاملDetailed process of adsorption of alkanes and alkenes on zeolites.
The adsorption of alkanes and alkenes on zeolites is investigated by comparing the adsorption characteristics for three types of zeolite: ferrierite, ZSM-5, and mordenite. The activation energy for the diffusion of propane and n-butane on ferrierite and the heat of adsorption of C(2)-C(4) alkanes and alkenes on zeolites and silica are estimated based on Fourier transform infrared spectroscopy, ...
