The utilization of ethanol as a component of motor gasolines is an extremely effective way to increase the detonation resistance and environmental properties. In Russia, despite the existing prerequisites for the development of bioethanol industry, the real production of bioethanol is not executed, which is associated with its high price. One of the promising ways of leveling this drawback is the utilization of water-cut waste from its production, involving ethyl alcohol impurity concentrate (EAIC) instead of pure ethanol.

Multifunctional additives should be added into motor gasoline to raise the life of engine parts, increase the engine power, as well as reduce the exhaust emission and fuel consumption. This research article proposes new insights to produce modern multifunctional motor gasoline additives. The main components of these additives are detergents, corrosion inhibitors, and friction modifier.

The depletion of fuel production and raising ecological issues have paid the progress of biofuels in the entire world. Among different biofuels is introducing renewable fuel additives as prospective beneficial blendstocks towards fulfilling systematic, low-carbon technologies internal combustion engines. This research article proposes a new approach to formulate a Fuzzy modeling for examining various promising alternative renewable oxygenated compounds, including ethanol, isopropanol, MTBE, and 2-methyl furan into heavy hydrocracked gasoline a base fuel.

We establish property (T) for a large class of groups graded by root systems, including elementary Chevalley groups and Steinberg groups of rank at least 2 over finitely generated commutative rings with 1. We also construct a group with property (T) which surjects onto all finite simple groups of Lie type and rank at least two.

The Russian Federation prohibited the distribution of herbal mixtures with synthetic aminoalkylindoles JWH-018 and JWH-073, agonist cannabinoid receptors, on January 22, 2010. The lack or low content of their native compounds in urine requires detailed identification of their metabolites, which are excreted with urine and are present in blood. Using gas and liquid chromatography-mass spectrometry, we identified a series of metabolites in urine samples from humans and rats that were products of the following reactions: (a) mono- and dihydroxylation of the parent compounds with hydroxyl groups located at aromatic and aliphatic residues, (b) carboxylation, (c) N-dealkylation and (d) N-dealkylation and hydroxylation.
