The paper presents data on the content of heavy metals in the leaves of woody plants growing under the conditions of the Kedrovsky coalpit, located in the central part of the Kemerovo Region. The object of the study was the trees of Scots pine and European white birch 10–15 years old. The content of such heavy metals as lead, copper, zinc, and iron in the birch leaves and pine needles was studied. The studies were carried out according to generally accepted methods. It has been established by investigations that under the conditions of the waste dump of the Kedrovsky coalpit in the leaves of the studied plants, there is an accumulation of elements, mainly associated with technogenesis, and impoverishment by such a biophilic element as iron. The maximum spectrum of heavy metals in comparison with the control accumulates birch dangling. Exceeding the threshold limit value of zinc in leaves and needles is revealed. It has been established that, in terms of the total concentration index, the level of accumulation of heavy metals in leaves and needles of the studied tree species growing under the conditions of the dump is estimated as low. The scientific significance of our research is that the obtained data can be used in the performance of ecological biomonitoring of woody plants in conditions of technogenic pollution.

The article presents the results of a theoretical and practical study of the inadequate attention of specialists in the field of physical culture and sports to addressing the problem of the low activity of the elderly in competitive sports and sports activities. The review of the research of foreign and domestic scientists studying the effectiveness of traditional means of physical culture and health on the indicators of health, psychophysiological and cognitive functions of an elderly person is presented. It is noted the need to continue searching for the means and methods of physical fitness and sports, as well as the specification of the amount of physical activity that contributes to improving the physical, mental, social health of older people. The presented analysis of the directive documents defining the strategy for the development of physical culture and sports in our country focuses attention on the importance of activating the competitive sports and sports activities of the older generation. The questionnaire survey of elderly women, systematically engaged in recreational swimming, showed that the main goal of the classes for them is to improve overall health. Along with this, the observed lack of desire to participate in competitions, along with actively manifested individual competitiveness in the process of classes, must be taken into account when organizing physical culture and sports and mass work with this contingent.

Pepper sweet is one of the leading cultures in the content of ascorbic acid. The use of its fruits, both fresh and recycled, allows satisfying the daily needs of the human body in ascorbic acid, not only during the season but also in the off-season. When canning sweet pepper changes occur in the product, therefore, All-Russian Scientific Research Institute of Irrigation Vegetable and Melon Crops employees set the task to determine the change in organoleptic parameters in canned pepper, depending on the storage time in the naturally–existing storage space. For research, sweet pepper varieties of our institute were used: Mramornyi, Atamor and Ludmila. The carried-out research work has shown that the biochemical composition and quality of the finished canned products, as well as fresh, primarily depends on the variety. Thus, the content of ascorbic acid in the Ludmila variety in fresh fruits was 1.2–1.3 times, and 1.3 times higher than the other studied varieties by the end of storage of finished products. The sugar/acid index, characterizing the taste of the produce, regardless of the grade, was above 7 units, which indicates a high quality of canned sweet pepper. Ludmila also distinguished itself by its taste qualities, in relation to other varieties. The tasting commission evaluated the fresh production of sweet pepper in the range of 4.1 Mramornyi, 4.4 Atamor and 4.8 grades of Ludmila on a five–point scale. After 90 days of storage of canned sweet pepper, the tasting assessment varied from 4.4 to 5.0 points, with further storage, it slightly decreased. Perhaps these changes occurred due to the diffusion of sugars from the product into the fill during storage.

The paper dwells on a mathematical model of the logistical system of transport services for persons with disabilities, and there have been analyzed factors that affect the time spent on their transportation. When developing methodology for optimizing the time costs of passenger transport of persons with disabilities, the following two basic transportation services have been taken into account: “Social Taxi”, which will transport only people with special health; b) vehicle system in combination with urban passenger transport, which will transport representatives of the group of people with restricted mobility together with all other passengers. The study found that in the case of insufficient access to the required environment, by the increase in the demand of disabled people for transportation by “social taxi”, travel costs are increased that results in increasing total costs of the carrier. When determining the expenses of passengers, it is necessary to take into account the additional time, which the disabled persons need for boarding and alighting in buses at the stopping points, on average 2–3.5 minutes.

Migration turns out to be one of the most debated topics in Europe and particularly in Malta, that it is obviously not a recent phenomenon. One cannot, however, overlook the fact that migration is stirring up the intense public debate which brings this topic under the close scrutiny of the local community. This paper examines the far-reaching economic, labour and social implications generated by the settlement of a foreign and multicultural population in Malta. In particular, the discussion identifies an exhausted domestic labour force which has led to the displacement of labour in certain low–skilled sectors, in favour of foreign workers. An analysis is also undertaken of the current public attitude towards the proliferation of foreigners in Malta, exploring the manner in which the Maltese express a negative sentiment to foreign presence in their home country. The conclusions presented throughout the paper, in terms of labour–economic impact and public perception, are heavily founded upon the latest data gathered from a diverse range of surveys conducted among the Maltese population.

The article identifies 4 groups of economic entities, which are the basic objects of influence in the industrial sphere. Their choice is made on the basis of the presented indicators: the vector for the implementation of the domestic market, the ability to expand the scope of implementation of the state financial and economic interests, the orientation of production to the market situation, the use of high-quality (“developed”) resources and the ability to produce a product with high added value, profitability of production and the ability to guarantee progressive development on the financial and economic basis of the country. Apart from this, the formation of the mechanism and methods of state support of economic entities showed that the implementation of priority financial and economic interest is dependent on foreign investments. The provisions of the methodological approach adopted in the industry of the Republic of Belarus to the selection of state support facilities are consistent with the previously mentioned fact that it does not take into account the probability of multidirectional sectoral values and priority financial and economic interests. These results make it possible to conclude that such a methodological approach does not take into account the situation when the export-oriented unit has the ability to be unprofitable. This situation is not excluded. This is justified by the foreign economic specifics, according to which to consolidate the positions of economic entities on the external perimeter will need to take into account more points than on the internal. For example, the stability of the currency, the dynamics of the market rate of foreign monetary units, the specifics of the country's exchange rate policy, the peculiarities of the tax legislation of other countries where products are sold, etc. Means that the argument for the choice of priority financial and economic interests and the factor of the performance of the system of ensuring socio-economic security of the industrial sector of the Republic of Belarus in the vector of industry values without taking into account the rationality of the structure of these interests cannot be considered complete and exhaustive.
