Organophosphorus Azoles Incorporating a Tetra-, Penta-, and Hexacoordinated Phosphorus Atom: NMR Spectroscopy and Quantum Chemistry

The review presents extensive data (from the author’s work and the literature) on the stereochemical structure of functionalized organophosphorus azoles (pyrroles, pyrazoles, imidazoles and benzazoles) and related compounds, using multinuclear 1H, 13C, 31P NMR spectroscopy and quantum chemistry. 31P NMR spectroscopy, combined with high-level quantum-chemical calculations, is the most convenient and reliable approach to studying tetra-, penta-, and hexacoordinated phosphorus atoms of phosphorylated N-vinylazoles and evaluating their Z/E isomerization

The Structure of Biologically Active Functionalized Azoles: NMR Spectroscopy and Quantum Chemistry

This review summarizes the data on the stereochemical structure of functionalized azoles (pyrazoles, imidazoles, triazoles, thiazoles, and benzazoles) and related compounds obtained by multipulse and multinuclear 1H, 13C, 15N NMR spectroscopy and quantum chemistry. The stereochemistry of functionalized azoles is a challenging topic of theoretical research, as the correct interpretation of their chemical behavior and biological activity depends on understanding the factors that determine the stereochemical features and relative stability of their tautomers. NMR spectroscopy, in combination with quantum chemical calculations, is the most convenient and reliable approach to the evaluation of the stereochemical behavior of, in particular, nitrogen-containing heteroaromatic and heterocyclic compounds. Over the last decade, 15N NMR spectroscopy has become almost an express method for the determination of the structure of nitrogen-containing heterocycles

Modeling of capillary-sorption process steam condensation in the system of microcapillaries of grain shells

The aim of this study is to simulate the capillary-sorption process of steam condensation in the system of microcapillaries of grain shells [1]. Modeling of the processes of intensive moisture transfer during drying of a number of materials was considered in [2,3]. In order to significantly reduce the time of moistening, moisture transfer by effusion is considered in the form of steam produced at low pressure (vacuum) with its further guaranteed condensation in micro-cavities (microcapillaries) of a porous shell of grain [4]. Study of intensity of moisture transport in accordance with the changes in concentrations of vapour along the length of the capillary in a vacuum proved the possibility of intensifying the process of moistening the grain before grinding. The obtained mathematical model will allow to calculate the values of the theoretical weight gain of moisture in microcapillaries depending on the parameters and the time of vacuum-sorption moisture

Development and implementation of blended courses for Russian language teachers in Russia and abroad

The growing popularity of massive open online courses (MOOC) stimulates teachers to appeal to the theory and practice of this philosophy. MOOCs are aimed at widespread involvement of students, improvement of their progress in studies, implementation of the principles of lifelong learning throughout life, support and development of their professional competence, etc. However, the mechanisms for implementing of the basic principles of MOOCs philosophy remain a subject of discussion. The article deals with theoretical approaches to solving a number of MOOCs problems connected with the use of a training video. The models for using a video content described in the article are given in the context of a blended Russian language learning project implemented at Kursk State University

Ways of intensification of the process of moistening the grain before grinding

The aim of this study is substantiation of ways of reducing the time required to process pre-wetting the grain before peeling, flattening, grinding [1]. A method of moistening the grain before grinding with preevacuation of its interior microvoids through the porous shell provides moisture transfer in the liquid phase. This moisture transfer requires the subsequent application of excess pressure to the penetration of moisture to the core of the grain and subsequent long-term otvalivayas grain. To significantly reduce the time of wetting is proposed to use a moisture transfer with effusion in the form of steam produced at low pressure (vacuum), then the guaranteed condensation in micropolitan porous shell of the grain. Study of intensity of moisture transport in accordance with the changes in concentrations of vapour along the length of the capillary in a vacuum proved the possibility of intensifying the process of moistening the grain before grinding

A New Family of Vinyl Selenocyanates with the Amide Function Based on the Reaction of Potassium Selenocyanate with 3-Trimethylsilyl-2-Propynamides

An efficient approach to a novel family of (Z)-3-amino-3-oxo-1-propenyl selenocyanates was developed based on the reaction of KSeCN with 3-trimethylsilyl-2-propynamides in the presence of ammonium chloride in methanol. The reaction was accompanied by a desilylation process. The products were not formed under the same reaction conditions in the absence of ammonium chloride, which was used for the first time in the reactions of selenocyanates with acetylenes. The use of this new methodology allowed the reaction to carry out in a regio- and stereoselective fashion as anti-addition affording vinyl selenocyanates with a (Z)-configuration in high yields

Sanitary assessment and technological indicators of goat milk

Milk and dairy products are indispensable for the full development and functioning of the body. In recent years, the demand for goat’s milk has increased. It has long been considered a source of health, especially in relation to people suffering from allergic diseases (including cow milk protein), with metabolic disorders, digestive disorders, etc. That is why the problem of obtaining high-quality goat milk is relevant and practically significant. Over the past few decades, interest has grown in a variety of biologically active substances of natural origin for their use as components of the diet of farm animals. Unlike antibiotics, growth stimulants and other synthetic drugs, phytogenics can be used in healthy animals for most of the productive period, providing a positive result in terms of quantity and quality of products. Based on this, we studied for the first time the effect of the plant product of stevia processing on the veterinary and sanitary indicators of goat milk. An experimental group of goats received stevia pulp together with the main diet. During the experiment, we found positive dynamics associated with the productivity of the goats of the experimental group. The use of an experimental feed composition provided positive dynamics in terms of the main indicators characterizing the technological value of milk. Thus, based on the data obtained, it should be concluded that the use of stevia pulp in combination with the basic diet provides positive dynamics for technologically significant indicators of goat milk, as well as increases the productivity of animals and ensures the production of products with high veterinary and sanitary characteristics

Regio- and Stereoselective Synthesis of (Z,Z)-Bis(3-amino-3-oxo-1-propenyl) Selenides and Diselenides Based on 2-propynamides: A Novel Family of Diselenides with High Glutathione Peroxidase-like Activity

The efficient regio- and stereoselective syntheses of (Z,Z)-bis(3-amino-3-oxo-1-propenyl) selenides and diselenides in high yields based on the nucleophilic addition of sodium selenide to 2-propynamides and sodium diselenide to 3-(trimethylsilyl)-2-propynamides have been developed. The first examples of the addition of a selenium-centered nucleophile to 2-propynamides with a terminal triple bond and diselenide anion to 3-(trimethylsilyl)-2-propynamides have been carried out. Bis(3-amino-3-oxo-1-propenyl) diselenides are a novel family of compounds, none of which has yet been described in the literature. The glutathione peroxidase-like activity of the obtained compounds has been evaluated and products with high activity have been found. It was established that diselenides are superior to selenides with the same substituents in glutathione peroxidase-like activity. The results of the structural studying of products by single-crystal X-ray diffraction analysis and 77Se-NMR data are discussed
