The article discusses the current state of the process of receiving petroleum products at a gas station in order to eliminate and reduce losses and cycle time. A methodology for preparing a standard for obtaining petroleum products is presented and the effectiveness of its use at a gas station is determined. A standardized sequence of actions made it possible to detect problems and losses and reliably evaluate the efficiency of production processes. Based on the established sequence of operations for the process of receiving petroleum products, the standard work instructions (SWI) indicate the time for performing a separate process operation, the total time of the production cycle, the trajectory of movement through the facility between workplaces, and the classification of work taking into account compliance with safety and environmental requirements. As a result of the redistribution of all operations in order to eliminate and reduce losses and process cycle time, the best sequence of actions was established, which ensured the efficiency of the process of receiving petroleum products and environmental safety during the operation of gas stations.

The purpose of the study was to study the effectiveness of using ultrafine copper particles as part of an enzyme-containing diet for broiler chickens. The research results indicate that each of the components of the proposed strategy influenced a certain functional system of the body with a subsequent range of adaptive changes, which ultimately led to a change in the efficiency of broiler rearing. In particular, it was found that the proposed substances have a growth-stimulating effect to varying degrees. Feeding the enzyme was accompanied by a maximum increase in the live weight of the experimental birds (13.75%), but in this case the maximum palatability of the feed was noted (a difference with the control of 6.7%). The strategy of complex introduction of enzyme and ultrafine copper was more effective and was accompanied by a decrease in feed costs in comparison with the group of introduction of only enzyme, with a difference in live weight with the control of 13.68%.

The research features new processing methods of extraction of active antibacterial components from Siberian berries. The paper describes the content of biologically active agents and antibacterial dynamics in blackcurrant (Ribes nigrum L.) and common sea buckthorn (Hippophae rhamnoides L.) extracts. The study involved an analysis of the bactericidal biologically active agents in the extracts. The experiment revealed the main effect and synergism of the principal components, i.e. flavonoids, tannins, and vitamin C. It also established the leading role of the phenolic substances (flavonoids, tannins, phenolic acids, and glycosides) in the antibacterial influence on cultures of some kinds of pathogenic, potentially pathogenic, and unwanted microflora. The authors revealed some regularities of useful substances extraction in the conditions of ultrasonic processing. The optical density indicator of extracts during extraction helped to establish the optimum parameters of the process: mash ratio – 1:15; ultrasonic exposure frequency – 22 kHz. The experiment determined the mass fraction of extractive substances and active components, as well as the values of extraction coefficients of the berry raw material. Tannins and vitamin C were more extractable than flavonoids. The research also touched upon the impact of ultrasonic processing on the acceleration of extraction. When processing water-alcohol solutions of the raw material by ultrasonic irradiation with an intensity of 2 W/cm2 and a frequency of 22 kHz, the extraction duration fell from 300 to 15–20 minutes before the comparable values of balance concentrations of extractives were reached, in comparison with the control samples.

The results of research on improving the technology of flour confectionery and bakery products enriched with components of secondary resources of fruit raw material to increase their nutritional value are given in the article. The purpose of the study is to substantiate the production of flour confectionery and bakery products with increased nutritional value when using secondary resources of fruit raw material on the basis of studies of quality indices of semi-finished and finished products. Different samples of secondary fruit raw material in the form of cake and meal have been analyzed. A secondary product is obtained after pressing the berries or after the extraction with water and water-alcohol solvents. It is suggested to dry up secondary products in the form of cake and meal in the convective dryer at the temperature of 40°C to the humidity of 20 % to improve their technological properties. The possibility of adding extra raw material into the dough for producing butter biscuits and bakery goods has been studied. It has been established that consumer characteristics of bakery goods with added dried-up blackcurrant cake are worse than those of check samples. By results of research it has been determined that introduction of the dried-up cake of blackcurrant berries into dough for producing butter biscuits doesn't influence its properties and physical and chemical properties of a finished product. It has been found that the optimum dosage of the additive is 15% of the flour mass which doesn't lead to the worsening of organoleptic factors of finished products. The data on the analysis of the chemical composition of butter biscuits with added cake of blackcurrant berries ispresented. It has been found that the content of food fiber in the product increases by 33.5% compared to the check sample. Produced biscuits are enriched with trace elements and mineral substances (ferrum, potassium, calcium, magnesium, chlorine), P-active substances and antotsiana. Experimental and calculated data prove the possibility of using the cake of blackcurrant berries for the production of butter biscuits with increased nutritional value.

The article represents a comparison of rare species morphometric indicators and seed productivity of the genus Iris in the South Urals. It’s shown that I. scariosa, I. humilis and I. pseudacorus habitus deteriorate and seed productivity decreases under culture conditions, but I. pumila samples in culture outstrip plants in natural habitats. I. pumila is promising for cultivation in the South Ural region

The purpose of the research is to give a complex hygienic evaluation of environment state in Donetsk region and to determine the degree of their potential danger to population health. It includes air pollution, water contamination, state of soil. Nearly 43000 samples of air, 32000 drinking water samples and 4500 soil samples were analyzed. Regions with the highest rate of environmental pollution were defined. It was found that the main sources of environment pollution in Donetsk region are ferrous and nonferrous metallurgy enterprises, power, coal, building industry and transport. All other sources ac¬count for only 5-10% of total emissions. Level of harmful technogenic pressing on population’s health was determined.

This study determined the effectiveness of a developed MOOC 'Statistical Analysis and Information Processing for Research' in enhancing Kazakhstan's young researchers' research skills. This study employed pedagogical experience generalization, pedagogical observation, discussion, questioning, and mathematical statistics to process experimental results. Criteria were selected to assess MOOCs' impact on participants' skills. Pearson's goodness-of-fit criterion was utilized as the experimental results were categorized into high, sufficient, and low levels. Following the MOOC's implementation, the experimental testing results showed a significant improvement compared to the control group. This comparison was valid for a random selection of students with a probability of 0.99, with a correlation coefficient of 0.9. Our study encompassed 340 participants. The MOOC's implementation led to a 12.1% increase in the number of experimental group students receiving high assessments for their scientific work, a 14.1% increase in the number of experimental group students obtaining average scores, and a 26.2% increase in the number of control group students who did not partake in the MOOC and obtained low grades. An experimental evaluation of the effectiveness of implementing the MOOC in three languages confirmed the hypothesis that MOOC-based learning technology is more effective than traditional methods in enhancing Kazakhstan's young researchers' research skills.

Objective: This study examined the impact of family size and type on maternal rejection and its relationship with emotional-behavioral difficulties in children with ADHD compared to those typically developing. Method: The participants were mothers of 7- to 12-year-old children with ADHD (n = 102) and mothers of typically developing children (n = 102) in Kazakhstan. In this cross-sectional study, multiple linear regression analysis was performed to explore the relationship between variables. Results: Family size affected maternal rejection after accounting for children's emotional-behavioral difficulties only in mothers of children with ADHD. The effect of family type on maternal rejection was statistically significant in both groups. Family size exacerbated the relationship between children's emotional-behavioral difficulties and maternal rejection only in children with ADHD. The moderating effect of family type was not found in either group. Conclusion: Our findings suggest that family size and type contribute to maternal rejection of children with ADHD.

The COVID-19 lockdown has had a significant impact on mental health. Patients with eating disorders (ED) have been particularly vulnerable. (1) To explore changes in eating-related symptoms and general psychopathology during lockdown in patients with an ED from various European and Asian countries; and (2) to assess differences related to diagnostic ED subtypes, age, and geography. The sample comprised 829 participants, diagnosed with an ED according to DSM-5 criteria from specialized ED units in Europe and Asia. Participants were assessed using the COVID-19 Isolation Scale (CIES). Patients with binge eating disorder (BED) experienced the highest impact on weight and ED symptoms in comparison with other ED subtypes during lockdown, whereas individuals with other specified feeding and eating disorders (OFSED) had greater deterioration in general psychological functioning than subjects with other ED subtypes. Finally, Asian and younger individuals appeared to be more resilient. The psychopathological changes in ED patients during the COVID-19 lockdown varied by cultural context and individual variation in age and ED diagnosis. Clinical services may need to target preventive measures and adapt therapeutic approaches for the most vulnerable patients.

The modern system of national education, developing in the competence paradigm, puts on the agenda the need to form students' communicative skills that belong to the category of critical competencies of a meta-subject nature. The article discusses the methodological features and pedagogical conditions for forming meta-subject skills of schoolchildren in foreign language lessons. An attempt is proposed to determine the characteristics of the meta-subject approach, including a complex of personality traits that allow the student to act in a given communication situation at the level determined by the age-related psychological characteristics and the possibilities of the social experience of a younger student. The authors used the following research methods: utilizing the study and generalization of pedagogical experience and the survey method, the communicative, regulatory - behavioral and motivational characteristics of a younger student, which must be taken into account when introducing pedagogical technologies focused on meta-subject results in foreign language lessons, are concretized. The analysis of the real practice of an educational activity is aimed at establishing a set of features of the pedagogical support of the meta subject approach within the framework of the "foreign language" discipline in primary school. Based on the analysis of scientific literature on research and practical experience, several strategies have been identified that ensure the effective implementation of meta-subject results in younger students in foreign language lessons.
