The article is devoted to the May Revolution in Argentina and the 25th anniversary of the opening of the representation of the Argentine Republic in Ukraine. The May Revolution has its origins in the events of May 25, 1810. It was the day when the foundation act declaring the creation of the Argentine state was issued. Two hundred and eight years ago, the word “freedom” arose in the hearts of Argentines. Remembering the most significant moments of history, Argentines preserve and cherish their desire for peace and freedom. Ukraine and Argentina are negotiating bilateral agreements on social security, extradition, mutual assistance in criminal and civil cases, tourism, cinematographic production, intellectual property protection, environmental safety. More than 50 bilateral agreements have already been signed by the two countries in recent years. The enhancement of cooperation is to be reiterated at the meetings of the Joint Commission for Economic and Trade Affairs in Buenos Aires. It is expected that those meetings would result in visits of delegations of Ukrainian businessmen to Argentina and vice versa. The author draws attention to the unveiling of a commemorative sign dedicated to the father of the Argentine nation, General Don José de San Martín, in the garden square in front of the Embassy of the Argentine Republic to Ukraine. The article also focuses on active efforts to spread the culture of Argentina through the Argentine House in Kyiv that offers a wide range of activities, including Argentine literature workshops, tango and folk dance classes, tourism seminars, movie screenings. The author argues that nothing brings people closer together than culture and concludes that relations between Ukraine and the Argentine Republic are at a high level. Keywords.

Reflective video-recording in language-learning classes is engaging, effective and fun. Practices and techniques are highly transferable to other subject areas. In developing speaking competence and confidence, language teachers are constantly assessing and balancing the need to address either accuracy and/or fluency.   Video-recording in a supportive, sensitive environment with learners and teachers who know each other well can capture spoken language and visual communication and allow it to be worked on, like words on paper, as a text for analysis, discussion and feedback in a variety of ways, both top-down and bottom-up. Accuracy can be addressed without affecting fluency as the sample of speech is recorded, not live.   The use of video-recording and play-back lends itself particularly well to a wide range of language-learning approaches and methodologies, including Community Language Learning (CLL), Dogme ELT, task-based learning (TBL) and others, under the umbrella of a communicative approach.   Classes using video-recording are spontaneous and adaptive, very learner-centred and allow for responsive and sensitive adjustment to students’ needs, strengths and areas for improvement as well as cultural and linguistic considerations.   This case study will include edited video extracts of a video of a mock speaking test being analysed by a class of learners who are all engaged in practising for this this style of test. They share feedback in a supportive, affirming atmosphere. There is a high level of engagement and interaction.   The video of this class, in turn, is shown to a group of teachers, who use it as a text to workshop ideas for delivering feedback and generating learner-led discussion for meaningful alternative authentic self-assessment. The teachers also discuss the use of technology-enhanced learning in regard to this use of video.   Another layer of video shows a professional development session with a wider body of teachers leading into discussion on using video in professional development of teachers and teacher-trainers.   This case-study session will involve explanation of the methodology and pragmatics of this simple way of using video, recorded with students’ and teachers’ phones in class to enhance reflective learning with a range of clips of the various layers.

The issues of ensuring the environmental safety of the functioning of the processing industry in the agro-industrial complex of Russia, on the basis of economic mechanisms, are considered. The high level of resource use in the processing of agricultural products contributes to environmental pollution, reduces the competitiveness of the industry, increases the level of costs. A rather large deterioration and obsolescence of the equipment of the processing enterprises of the agro-industrial complex does not allow for the environmentally safe processing of agricultural products. Of particular concern are enterprises of the meat processing industry, which produce waste, which creates an unfavorable sanitary and epidemiological situation in the regions. In this regard, it is necessary to develop such a system of economic incentives for the implementation of resource-saving projects of the processing industry enterprises in the agro-industrial complex, which would improve the environmental and economic efficiency of the studied industry. Given the high capital investment in modern resource-saving equipment, it is advisable to pay attention to the sources of funding for these projects on a preferential basis. Among the measures for the economic stimulation of projects for the processing of agricultural products by the industrial method, the article proposes both credit and financial instruments, including preferential loans and leasing, and preferential taxation, and an environmental fee. In order to stimulate projects for the acquisition of resource-saving equipment in the processing of agricultural products, it is proposed to use such an effective tool as accelerated depreciation, which allows manufacturers to reduce costs when replacing old equipment with more modern ones. In order to increase risk management efficiency, when implementing projects for industrial processing of agricultural products, it is proposed to use public-private partnership tools that minimize risks, including environmental ones, due to their redistribution between participants, based on such forms as delegation of management and concessions.

Analysis of the advantages and determination of the efficiency of machines for subsoil application of liquid nitrogen fertilizers in resource-saving technologies by evaluating the quality of the DRAGON 6000 applicator. Research methods: theoretical (analysis and synthesis of information resources); experimental field; statistical (mathematical processing of research results) according to generally accepted methods. Results. Experimental studies of the influence of the speed modes of the injector wheel of the DRAGON 6000 applicator for application of liquid nitrogen fertilizers CAS on the quality of the technological process were carried out. It is established that during radical fertilization with liquid fertilizers of corn crops with a row spacing of 70 cm the unit is able to provide a daily yield of 120 hectares in 16-row performance and projected 180 ha - in 24-row, provided proper organization of work and staff training. It is noted that in the conditions of growth of prices for mineral fertilizers and climate change introduction of ecological approaches and resource-saving technology of entering CAS on the basis of the DRAGON 6000 applicator is an urgent task which will allow to compete successfully in the world market. Conclusions. Analytical review of domestic and foreign information resources confirms that the technology of subsoil application of liquid mineral fertilizers, in particular urea-ammonia mixtures (CAS), compared with the application of dry and other liquid fertilizers, is becoming more widespread due to better efficiency, which is a derivative of plant nutrition, rational positioning of fertilizers at the required depth, minimization of evaporation losses, improved drought resistance in the cultivation of crops, and also has significant benefits by reducing losses of active substance, ease of adjustment and management of the work process. Studies have confirmed the possibility of providing the presented design of the machine a constant depth of penetration of needles into the soil with a wide range of humidity and different speeds, as well as the ability to choose rational protection zone for cultivation of corn plants without damage to achieve acceptable efficiency of liquid fertilizers. LLC "ROPA-UKRAINE" presents to the market to consumers the applicator of the Ukrainian production DRAGON 6000 which passed production check on the area of 500 hectares during continuous entering of liquid fertilizers of CAS on vegetative plants of wheat and in the course of interrow (radical) entering of CAS on corn crops. 1100 hectares. With a change of speed in the range (5… 10) km / h, in difficult conditions of work at excess soil moisture, the DRAGON 6000 applicator stably provides depth of entering into soil of needles 6 cm long on depth of 4,9 cm in a protective zone on distance 5 cm from the stems. Under these conditions, the fixation of fertilizers is high quality, and damage to plants is not observed. According to the results of experimental research, the applicator guarantees high indicators of technological reliability and quality of the technological process, has good transport characteristics and lateral stability when driving on field roads.

The search for resource-saving and environmentally friendly technologies and technical solutions in the production of food products should occur through the development and development of new analytical methods and constructive measures, which will lead to progress in this field not only in our country but also abroad. The efficient use of processing facilities has always been characterized by its high level of mechanization. Drying is one of the most widespread technological operations in various industries of processing and food production, in particular in the preservation of raw materials. Prospects for the development of drying technologies include reducing energy costs for moisture extraction; improving the quality of dried products; development of highly efficient universal equipment; ensuring the environmental safety of drying plants. When studying different physical phenomena in the process of vibration drying, two methods of research are used, which allow to obtain quantitative regularities. In the first method is used experimental study of specific properties of a single phenomenon, in the second - based on a theoretical study of this problem. The advantage of the experimental research method is the reliability of the obtained results. The analysis of literature sources is carried out and the necessity and possibility of creation of new designs of dryers using infrared influence on the product and vibrational vibrations of the working container for intensification of the drying process is substantiated. The proposed design of an experimental laboratory drying unit for drying granular and granular materials in a vibrating boiling layer allows to identify patterns of changes in the parameters of the drying process, to obtain data to optimize the process and to develop a method of engineering calculation of devices for infrared drying.

The aggravation of the environmental situation in major cities of the Russian Federation has been observed in recent years. A significant contribution to the deterioration of the quality of the urban environment has a large number of vehicles and consequently the number of gas stations. They are generally concentrated within the city limits. As a result of the high level of competition of oil companies in the gas station market and the large consumption of liquid fuel oil by the urban population there is a point building of gas stations on free sites of urban development. The question of the need to improve the ecological safety of urban gas filling stations is acute and remains extremely relevant in our time. On the basis of the results of theoretical, numerical and experimental studies obtained by the authors, factors influencing spread of harmful substances from emission sources at gas stations have been identified, and their significance was established. The identified factors formed the basis of a multi-criteria analysis of the environmental impact of emissions from sources at gas filling stations. The authors have developed a methodology for assessing environmental safety of urban gas filling stations, which allows to assess the degree of impact of gas filling stations on the urban environment and to reduce their negative effect.

The article presents the genetic characteristic of the Chukchi reindeer breed. The object of the study was of the Chukchi reindeer. In recent years, the number of reindeer of the Chukchi breed has declined sharply. Reduced reindeer numbers could lead to biodiversity loss. The Chukchi breed of deer has good meat qualities, has high germination viability and is adapted in adverse tundra conditions of Yakutia. Herding of the Chukchi breed of deer in Yakutia are engaged only in the Nizhnekolymsky district. There are four generic communities and the largest of which is the agricultural production cooperative of nomadic tribal community «Turvaurgin», which was chosen to assess the genetic processes of breed using microsatellite markers: Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276. It was found that microsatellite markers have a wide range of alleles and generally have a high informative value for identifying of genetic differences between animals and groups of animal. The number of identified alleles is one of the indicators of the genetic diversity of the population. The total number of detected alleles was 127. The Chukchi breed of deer is characterized by a high level of heterozygosity, and the random crossing system prevails over inbreeding in the population. On average, there were 7.9 alleles (Na) per locus, and the mean number of effective alleles (Ne) was 4.1. The index of fixation averaged 0.001. The polymorphism index (PIC) ranged from 0.217 to 0.946, with an average of 0.695.

Several outbreak prediction models for COVID-19 are being used by officials around the world to make informed-decisions and enforce relevant control measures. Among the standard models for COVID-19 global pandemic prediction, simple epidemiological and statistical models have received more attention by authorities, and they are popular in the media. Due to a high level of uncertainty and lack of essential data, standard models have shown low accuracy for long-term prediction. Although the literature includes several attempts to address this issue, the essential generalization and robustness abilities of existing models needs to be improved. This paper presents a comparative analysis of machine learning and soft computing models to predict the COVID-19 outbreak as an alternative to SIR and SEIR models. Among a wide range of machine learning models investigated, two models showed promising results (i.e., multi-layered perceptron, MLP, and adaptive network-based fuzzy inference system, ANFIS). Based on the results reported here, and due to the highly complex nature of the COVID-19 outbreak and variation in its behavior from nation-to-nation, this study suggests machine learning as an effective tool to model the outbreak. This paper provides an initial benchmarking to demonstrate the potential of machine learning for future research. Paper further suggests that real novelty in outbreak prediction can be realized through integrating machine learning and SEIR models.
