The University

Training of highly qualified specialists is a significant factor for the consistent progress in any branch of economics. Kemerovo State University provides training of specialists for the coal mining region in Russia. Nowadays, the University tends to increase the proportion of foreign students as well. Most of these are students from neighboring countries, such as Tajikistan, Uzbekistan, Kyrgyzstan, Kazakhstan, where raw materials industries, including mining, are developed. Taking into account the multi-ethnic diversity of students at Kemerovo State University, we analyzed the experience and determined the worthwhile forms of organizing independent activity in EFL teaching. Among the forms of independent activity, we introduced independent reading, preparing thematic presentations, written tasks based on video content, and writing thematic essays. Organizing independent work in the educational process, which involves a large number of multinational groups of students, we took into account the following conditions. We considered such particular qualities of contemporary students as their general need in flexible learning environment as well as in self-expression; we took into account their interest in new knowledge and motivation for self- improvement, and at the same time, lack of desire for completing reproductive types of tasks, along with fragmented thinking.

The development of new plant growth regulators based on products of chemical processing of plant raw materials is currently an urgent task for increasing yields in agricultural production. On the basis of carboxymethylated plant materials, "Eco-Stim" plant growth regulator has been developed. The purpose of this work is to study the effect of the storage conditions of solutions of carboxymethylated plant materials in "Eco-Stim" as part of the preparation on their rheological and growth-regulating properties. The rheological properties of the aqueous systems of carboxymethylated pine, sunflower, and oat chaff have been studied at concentrations of 0.2–15%. It is established that the change in viscosity as a result of the shear rate of the systems studied is more complex in comparison with aqueous solutions of Na-CMC. Storage of solutions of carboxymethylated vegetable raw materials for 20 months, as well as the processes of freezing and thawing for 6–9 weeks have practically no effect on the viscosity and growth regulating properties of carboxymethylated vegetable raw materials. The studied systems make it possible to increase the germination of wheat seeds Omskaya-36 to 80–87% and to increase the length of the root by 4–10 times and the stem by 1.5–2 times compared to the control.

The aim of this work is to review and analyze the data published in the modern scientific literature obtained in pharmacological, pharmacognostic and pharmacotechnological studies of various types of raw materials obtained from members of the family Lamiaceae L., which were sources of biologically active substances, pharmaceutical substances, total extracts and the drugs – with a neurotropic activity.Materials and methods. For the review, we used the information of scientific literature from open and accessible sources of the last twenty years, located in the scientific and technical libraries of institutions, as well as in electronic databases: Elibrary, PubMed, Scopus, Cyberleninka, GoogleAcademy, J-Stage. The search inquiries were: the species of the family Lamiaceae (Russian and Latin), the samples of medicinal plant materials based on them as well as the names of the drugs and biologically active substances obtained from these raw materials.Results. When working with the sources of scientific information, the main attention was paid to pharmacologic tests performed during the studies on laboratory animals and proving the presence of neurotropic activity in the studied objects – essential oils and extracts from plant raw materials: aqueous, aqueous alcoholic, and methanol ones. It has been established that the potential of the therapeutic and preventive application of pharmaceutical substances and drugs based on the medicinal plant materials obtained from 30 genera members of the Lamiaceae family, remains unrealized despite the close attention of various researchers.Conclusion. This review comprised 71 species from 30 genera. Despite the significant level of the previous study presented in the analysis of this publication, an enormous potential of this family’s species remains unexplored. In the future, they can be of both – pharmacognostic and practical interest, in particular, in creation of new medicinal preparations of the neurotropic action based on them.

The possibility of recovering the spent cooking solution with the replacement of the missing amount of lignifying reagents in the oxidative-organic solvent cooking of non-woody plant raw materials (rice husk) with preliminary alkaline treatment and the production of technical pulp with desired properties is shown. Analysis of scientific and patent information revealed that two methods of regeneration are used for regeneration of spent cooking solutions during oxidation-organosolve cooking: azeotropic distillation and return of part of the spent cooking solution for re-cooking with the completion of the missing amount of reagents. For the oxidation-organosolvent cooking non-wood plant materials the most promising is the second option. To avoid the preservation of mineral components in industrial pulp, non-wood plant materials are subjected to alkaline treatment. It has been established that to obtain technical pulp with recovery of the spent cooking solution, it is required two times less acetic acid and 1.7 times fresh water as compared to oxidation-organic solvent cooking under standard conditions with a constant amount of caustic soda.

Summary In the study, the relationships were investigated among N, P, Fe, Zn, Mn and Cu, in medicinal plant raw materials (herbal bags) and their water-soluble chemical forms in infuses. 42 independent samples of plant materials were chosen, represented by different morphological plant parts as herbs, leaves, flowers and fruits. The elements were determined by UV/Vis spectrometry (non-metals), and FAAS (metallic elements) after previous mineralization of plant samples (total concentrations), and directly in herbal teas (water-extractable forms). Most frequently the correlations between non-metals and Zn and Mn occurred, both between their total contents the water-extractable forms. Statistically significant correlations were also found in pairs: Zn-Mn, Fe-Zn, Mn-Fe, and Cu-Zn. Application of multivariate analysis revealed that cluster analysis grouped the studied samples into clusters with similar levels of the analyzed elements, and principal component analysis allowed the identification of water-extractable Zn, P-PO4 and water-extractable Cu as the most crucial factors determining the differentiation of the studied plant samples.

The research results concerning the application of physical methods of plant raw materials influencing - fresh beetroot - to inhibit microorganisms of Salmonella genus were presented in the work. Pathogenic microorganisms of Salmonella genus pose a threat to humans, being causative agents of typhoid fever, paratyphoid fever and other salmonellosis. The use of effective and available physical methods of influence in the fruit and vegetable processing technology allows us to ensure the maximum conservation of physiologically valuable components of the raw material and its safety. Microwave (microwave field) and ultraviolet radiation were chosen as physical methods for research. The sterilizing effect of the microwave field was clearly expressed - the bacteria survival after such a treatment was 2 or more times less than during heat treatment. Treatment with ultraviolet radiation has a bactericidal effect and is characterized by a minimal effect on the plant materials organoleptic properties. A comparative assessment of the effectiveness of the inhibition of the Salmonella test culture on diced fresh beets after treatment with the selected physical methods was carried out during the study. The samples temperature rose up to 43–46 °C under the influence of a microwave field in the selected mode with a power of 400 W, a duration of 40 s, and a flux density of 0.44 W / cm2. Treatment with ultraviolet (UV) radiation in the C-band (wavelength 253.7 nm) was carried out for 15 min with a dose of 50 kJ / m2 with a total power of ultraviolet lamps equal to 60 V. Processing of fresh chopped beets with UV radiation reduced the number of microorganisms by 5 orders of magnitude from the initial amount. Processing in a microwave field allowed to reduce the initial seed contamination of raw materials by 7 orders of magnitude. Sequential processing in a microwave field and subsequent ultraviolet radiation allowed us to reduce the initial beets seedling by 8 orders of magnitude. The combination of processing methods (microwave + UV) showed the effectiveness of their application to reduce pathogenic microflora.

The creation and the use of genetically modified products has become a tendency in the development of agricultural and food technologies. The area of agricultural land under genetically modified plants is constantly growing. Todays the process of using GMOs and the expediency of their creation is a debatable issue. The modification of the genome of traditional agricultural cultures gives them resistance to pesticides, pests, diseases, which cause to the significant an increase of harvest and improved quality and taste characteristics. However, the effects of GMOs on the environment and the body of animals and humans have not been fully studied, and therefore the thoughts of scientists are differ on the benefits and risks of genetic engineering. Recently, the scientific literature has data on the negative effects of GMOs on animals and humans, in particular, on the morphofunctional state of organs and systems of the body, reproductive function, immune status, biochemical parameters of blood and urine. Every year the number of new genetically modified plant lines is growing, so today, the need in research of plant raw materials and feed for animal  on the presence of GMOs is very important and actual. The article presents the results of research on the detection of GM ingredients in plant raw materials and in products of its processing, feed for productive and unproductive animals, etc. In 2020, 1215 samples were investigated by polymerase chain reaction with detection in real-time (PCR-RT), and it was found out that only 0.3 % from total amount were positive. From the studied samples, the most positive samples were found in samples of rapeseed, soybeans and feed for productive animals. In 27 samples of rapeseed, the number of positive samples was 7.4 %, in them were detected the target sequences of the terminator NOS (T-NOS) T plasmid Agrobacterium, and genes Pat and EPSPs. In 6 samples of  soybean, the number of positive samples was 16.7 %, in them were detected the target sequences of the 35S promoter of cauliflower mosaic virus (CaMV) and the terminator NOS (T-NOS) T of the plasmid Agrobacterium. Also there was found GM ingredients in compound feeds for farm animals and poultry, in 6 samples the number of positive samples was 16.7 %, in them were detected the target sequences of the terminator NOS (T-NOS) T plasmid Agrobacterium. Conducted studies indicate that transgenic plants are in circulation in the agricultural market, so it is necessary to constantly control animal feed, plant materials and seeds for the presence of GM sources.
