Objective: Considering the impact of inaccuracy and errors in measuring the thickness of the fl ange of wheelsets on the frequency of uncoupling for unscheduled repairs on the railways of the Republic of Uzbekistan. Conducting an analysis of the impact of uncoupling freight cars for unscheduled wheelset malfunctions repairs. Methods: Methods of combinatorial and statistical analyzes of the initial data are used. Results: A detailed analysis of car uncoupling for unscheduled repairs on the railways of Uzbekistan has been carried out. The probabilities of car uncoupling operation in TR-2 (current repair) due to the “thin fl angeˮ malfunction have been determined. The infl uence of inaccuracies and measurement errors on the frequency of uncoupling of cars for such a repair is estimated. Practical importance: The results obtained contribute to the deepening of knowledge about the possibility of the infl uence of inaccuracies and errors in measuring the thickness of the fl ange of wheelsets on the performance of cars.

Introduction. The solution to the problem of ensuring demographic growth is one of the most pressing issues of the state policy. In 2007, Russia’s demographic policy was supplemented by new measures to stimulate the birth rate. The objective of this paper is to analyze the effectiveness of the demographic policy programs aimed at supporting families and natality using the case studies of the Russian Federation and the Republic of Tatarstan. Materials and Methods. To identify the impact of measures to stimulate the birth rate, the method of regression analysis was used; time series based on age-specific birth rates for each age group were presented. Results. The data obtained showed that the steady trend of increasing the total fertility rate in Russia and Tatarstan since 2007 was almost completely related to the meas- ures under consideration, whereas the number of births was affected by many other factors. According to the results of the study, the impact of measures to increase the birth rate in the Republic of Tatarstan is slightly higher than in Russia as a whole. Discussion and Conclusions. State support measures reduce the costs associated with the birth of a child and can encourage women to have children, which con- firms the hypothesis of the positive impact of the state fertility policy. For a more accurate assessment of the effectiveness of the demographic policy measures, it is advisable to take into account the changing social and economic conditions of life in a region, as well as the consequences of the earlier or present-day demographic policy measures. The results of the study are of practical importance and may be used in the development of demographic policies in the country and in the region.

Самшит (Buxus colchica Pojark.) является реликтовым видом, на Кавказе известен от среднего до верхнего плиоцена. Целью представленной исследовательской работы является изучение лесопатологического состояния самшита и проведение дальнейшего мониторинга в условиях инвазии Cydalima perspectalis в 2014 г. По результатам исследовательской работы, проводимой в период 2011 – 2016 гг., среди микобиоты самшита выявлено 20 видов. По нашим наблюдениям, в естественных насаждениях и городских посадках самшита формируются различные комплексы грибных патогенов, включающих и опасные (Cylindrocladium buxicola и Volutella buxi). По результатам анализа повреждений, вызванных энтомофауной, значимым вредителем для самшита стала C. perspectalis, а остальные, отмеченные авторами, виды практического значения не имеют. Значимые повреждения C. perspectalis с 2015 г. отмечены в горных территориях на высоте до 500 м н.у.м., а в 2016 г. самшитовая огневка продолжила распространение и покорила самшит во всех его местообитаниях на территории Республики. С 2015 г. по ходатайству Государственного комитета Республики Абхазия по экологии и охраны природы принято решение о борьбе с вредителем. Мониторинг состояния самшита на территории Республики Абхазия, показывает, что благодаря проведению защитных мероприятий происходит не только сохранение, но и восстановление крон самшита. При полной дефолиации самшит сохраняет способность к восстановлению кроны при условии целостности коры на стволах и побегах. Сохранность популяции самшита зависит на данный момент от мероприятий, проводимых человеком. Buxus colchica Pojark., is a relict species. It is known in the Caucasus from the middle to the upper Pliocene. The aim of the research work is to study the forest pathological state of Buxus and monitoring in the conditions of invasion of Cydalima perspectalis in 2014. According to the results of the research carried out in 2011–2016, 20 species are found among mycobiota of Buxus. According to our observations, different complexes of fungal pathogens are formed in natural stands and urban plantations of Buxus, including dangerous ones (Cylindrocladium buxicola and Volutella buxi). According to the results of the analysis of damages caused by entomofauna, C. perspectalis became a significant pest for boxwood, and the other species registered by us have no practical importance. Since 2015 a significant damage of C. perspectalis is noted in the mountainous areas up to 500 m above sea level, and in 2016 the Buxus pest continued its distribution and subdued the Buxus in all its habitats on the territory of the Republic. Since 2015, at the request of the State Committee of the Republic of Abkhazia on Ecology and Conservation, a decision has been taken to combat the pest. Monitoring the state of boxwood in the territory of the Republic of Abkhazia shows that thanks to the implementation of protective measures, not only the preservation, but also the restoration of the upper branches of Buxus trees is taking place. With complete defoliation, Buxus retains its ability to restore the upper branches of tree, provided that the cortex is intact on the trunks and shoots. Preservation of the boxwood population depends at the moment on the human activities.

Water plays a very important role in supporting human life and other living beings as goods that meet public needs. Water is one of the declared goods controlled by the state as mentioned in the constitution of the republic of Indonesia. The state control over water indicated that water management can bring justice and prosperity for all Indonesian people. However, in fact, water currently becomes a product commercialized by individuals and corporations. It raised a question on how the government responsibility to protect the people's right to clean water. This study found that in normative context, the government had been responsible in protecting the people’s right over the clean water. However, in practical context, it found that the government had not fully protected people's right over clean water. The government still interpreted the state control over water in the form of creating policies, establishing a set of regulations, conducting management, and also supervision.

This paper deals with the right to property in general terms from its source in Roman law, which is the starting point for all subsequent legal systems. As a result of this, the acquisition of property rights is handled from the historical point of view, with the inclusion of various local and international literature and studies, as well as the legal aspect devoted to the respective civil codes of the states cited in the paper.Due to such socio-economic developments, state ownership and its ownership function have changed. The state function as owner of property also changed in Macedonia's property law.The new constitutional sequence of the Republic of Macedonia since 1991 became privately owned as a dominant form of ownership, however, state ownership also exists.This process of transforming social property into state or private (dissolves), in Macedonia starts from Yugoslavia through privatization, return and denationalization measures, on which basis laws on privatization have been adopted. Because of this, there will be particularly intensive negotiations regaring the remaining state assets.
