Abstract:
The sensible sources (namely; corn, wheat, barley, oat and rye) and molasses (procured from the local market of Rawalpindi), following enzymatic hydrolysis were subjected to fermentation to produce high fiber protein (HFP) and liquid protein as a by-product. The former can be used for human consumption and the later was considered fit for animal feed. Carbon dioxide gas produced during fermentation can be used as gas in beverages or converted into dry ice.

Abstract:
A study on the conformable model of alcohol consumption in Spain has been presented. For the proposed model, the existence as well as the uniqueness of the solution has been discussed with the help of fixed-point theory. An analytical technique, Variational Iteration Method (VIM), has been used to obtain the solution to the governing system of differential equations. With the help of suitable plots, the role of fractional order derivative has been highlighted. For decreasing values of fractional order derivative, decrease in the number of non-consumers and non-risk consumers has been observed.

The paper investigates the HCl concentration impact on the main and by-processes during the reduction 
 of 1-(2-nitroaryl)-1H-benzotriazole by tin (II) chloride in acidic aqueous-alcoholic medium. The authors have observed the formation of azoxy compounds in addition to the target amino derivative at low HCl content in the reaction mass. The use of 36% hydrochloric acid causes the alkylation of the formed amino compound with alcohol as a solvent.

Abstract:
The possibility of chemical modification of ED-24 epoxy resin peroxy derivative (PDER) by C9H4F16O fluorine-containing alcohol-telomer (FAT-C9) has been shown using 18-Crown and ZnCl2 catalytic system. The effect of catalyst amount, temperature and process time on the reaction rate has been studied. New peroxy oligomer containing fluorine atoms (FPO) has been synthesized and characterized. The FPO structure has been confirmed by IR-spectroscopy. It has been proposed to use FPO as an active additive to the polymeric mixes based on ED-20 industrial epoxy resin and TGM-3 oligoesteracrylate.

A stereospecific synthesis of (+)-muscarine iodide (1) has been achieved starting from D-glucose as a chiral precursor. The key steps of the synthesis involved a stereospecific cyclization of 3,5-di-O-mesyl derivative 3 into the 2,5-anhydride 4, the stereospecific catalytic hydrogenation of unsaturated derivative 6, and the C-4 epimerization of alcohol 12 by Mitsunobu reaction.

Dissolving in the lipids of biological membranes, ethanol changes their physico-chemical properties, disrupts the activity of membrane receptors, eventually disconnecting the connection of excitation with the contraction of c

Introduction: Chronic ethanol consumption leads to significant functional and structural changes in the mitochondria of the heart and brain, increasing generation of reactive oxygen species. Therefore, the search for substances, which improve the functional state of the mitochondria and, meantime, reduce the oxidative stress, is relevant. Materials and methods: 10-months-old Wistar female rats were used in the experiments. Chronic alcohol intoxication (CAI) was modelled by replacing drinking water with a 10% ethanol solution containing sucrose (50 g/L) for 24 weeks. Four groups were formed: 1
