Administrative and legal status of foreigners

Introduction. Today, the issue of administrative and legal status of foreigners is very important because our country needs clearer and more regulated legislation, which will not allow such phenomena as illegal migration, abuse of rights of foreigners in our country, non-compliance with duties, which leads to a violation of the law. In turn, the legislation must meet all requirements and not violate well-known human values and freedoms, so it is subject to change to improve the life of every person, regardless of his position in the state. Scientific research on foreigners and their legal and social status has been done by many researchers. Among them are such scientists as L. Voevodin, M. Inshin, T. Kirilova, M. Matuzov, M. Vitruk, O. Skakun, M. Mochulska., V. Marchenko, T. Drakokhrust, V. Zui, I. Boyko, et.al. The purpose of the paper is to study the administrative and legal status of foreigners in Ukraine, to compare Ukrainian legislation with the international standards, to analyze statistics and court practice on issues of foreigners, to analyze of scientific approaches to understanding the concept of “foreigner”. Results. With the proclamation of Ukraine as an independent state, the issue of the legal status of foreigners has become quite relevant and often studied among researchers. Certain gaps in the legislation create some problems of interaction between the country and foreigners, which can lead to restrictions on the inalienable rights and freedoms of foreigners. The paper analyzes the legal status of foreigners on the basis of research by scholars and legislation for a broader understanding. In addition, ways to solve problems are suggested in this work. The paper analyzes the case law as an example of how gaps in the legislation affect the process of expulsion or return of foreigners. Conclusions. After analyzing the current legislation on the rights and freedoms of foreigners and stateless persons, it can be stated that the rights and freedoms of foreigners and stateless citizens almost completely coincide with the rights and freedoms of citizens of Ukraine. Although foreigners are subject to individual restrictions on entry into Ukraine and the possibility of returning and forcibly expelling foreigners and stateless persons from Ukraine, such measures are used solely to protect the Ukrainian people and cannot be used unreasonably. It is important for every foreigner to be able to defend their rights and appeal to higher authorities in accordance with international standards. In practice, return and expulsion procedures are not always carried out effectively, which can lead to a significant delay in the procedure, which indicates that the implementation of these measures by special bodies is not yet perfect. Based on statistics and a review of current realities, we conclude that now is the right time to modernize the mechanisms for cooperation between special bodies and foreigners and give foreigners a wider range of rights before joining the EU and after Covid-19 time.

NANOCHROMIUM CITRATE: ANTIHYPERGLYCEMIC AND PANCREATOPROTECTIVE ACTION AGAINST UNDERLYING DEXAMETHASONE-INDUCED DIABETES MELLITUS

INTRODUCTION: The Ukrainian State Scientific-Research Institute of Nanobiotechnology and Resources Saving has received nanochromium citrate (NCC), a new chrome compound, by means of the electric pulse aquananotechnology method. OBJECTIVES: to determine nanochromium citrate efficacy with experimental dexamethasone-induced diabetes through the results of antihyperglycemic activity and its effect on the pancreatic histological structure. METHODS: diabetes mellitus was simulated by dexamethasone administration on 18-month male rats. The morphological structure of the pancreas was examined in comparison with metformin. Examination of the pancreas morphological structure considered the amount, distribution and size of the pancreatic islets and their cellular shape. RESULTS: on the 14th day of simulated diabetes mellitus the preventitive -therapeutic indication of nanochromium citrate promoted a decrease of glycemia level twice. The administration of nanochromium citrate with underlying diabetes mellitus is not inferior to metformin and its protective effect on the pancreas morphological structure exceeds the effect of metformin. CONCLUSION: nanochromium citrate of experimental dexamethasone-induced diabetes mellitus in rats decreases the glycemia level twice which does not differ reliably from the effect of metformin antihyperglycemic. The cytoprotective effect of nanochromium citrate produced on the histological structure of the pancreas is found to exceed metformin action.

RECOMMENDATIONS IMPROVEMENT FOR SUBSTANTIATION OF REQUIREMENTS FOR THE VALUES OF QUANTITATIVE INDICATORS OF ARMAMENT AND MILITARY EQUIPMENT UNIFICATION

The article deals with recommendations improvement for substantiation of requirements for the values of quantitative indicators of unification in requests for proposals for research and development works (R&D) on the development of samples of armament and military equipment (AME). Previously, it was proposed to substantiate these requirements on the basic unification level, taking into account the coefficients of factors that influence the level of unification, recommendations for their determination were given, but the coefficients of factors were adopted the same for all influencing factors. To achieve this goal, a group of five experts from the State Scientific Research Institute of Armament and Military Equipment Testing and Certification was formed. The experts were provided with a matrix questionnaire in which they had to provide evaluations of seven identified influencing factors by pairwise comparing of their significance. To increase the reliability of evaluation and eliminate errors, the survey was conducted twice. According to the results of the questionnaire, the ratings of the significance of the influencing factors were determined, which ranged from “+4” to “–3”. Taking this into consideration, the previously determined values of the coefficients of factors that influence the level of unification were adjusted and amounted to: for favorable factors: from 1.143 to 1.476; for adverse factors: from 0.524 to 0.809. The calculations of the value of repeatability factor at the basic level of unification of 70% on the example of tests of individual samples of AME were obtained. The results ranged from 68% to 79%. The analysis of the comparison of the unification level with the results of calculations in the previous work revealed that the changes are generally small (from 1% to 3%), but became closer to the results obtained in the tests in 80% of cases. The results of the study are recommended for use in practice during the setting of requirements in requests for proposals for research and development works on the development of samples of AME.

PERSPECTIVE WAYS OF DEVELOPMENT OF THE LABORATORY TESTING FACILITIES OF THE ARMED FORCES OF UKRAINE

The world practice of creating and modernizing specimens of armament and military equipment envisages carrying out numerous tests, checks and evaluations of the current technical conditions throughout the life cycle. The task of organizing and carrying out of tests, in particular mechanical, electrical and climatic, at the State Scientific Research Institute of Armament and Military Equipment Testing and Certification is entrusted to the scientific research laboratory that is a part of the scientific and technical complex of measurements of the Institute. Currently, the laboratory is not fully equipped with modern testing equipment. Therefore, the task of justification of the ways of development and providing the laboratory with test equipment for conducting mechanical, electrical and climatic tests of armament and military equipment specimens is urgent. The purpose of the article is to determine the perspective ways of development of the laboratory-testing facilities of the State Scientific Research Institute of Armament and Military Equipment Testing and Certification taking into account the modern development of armament and military equipment specimens. During the research general scientific methods of processing and systematization of information, in particular system analysis and synthesis of organizational and technical systems were applied. The peculiarities of the organizing and conducting mechanical, electrical and climatic tests at the enterprises of the defense-industrial complex of Ukraine were analyzed. It was established that the basis of testing, in addition to legislative acts and technological normative documents, is the availability of a modern laboratory testing base, since without the means of measurement and testing it is impossible to ascertain the stability, sustainability and durability of armament and military equipment specimens to the influence of external factors. The proposals for the purchase of the test equipment for ensuring tests in the direction of mechanical, electrical and climatic tests of State Scientific Research Institute of Armament and Military Equipment Testing and Certification are given.

Influence of HammecoTox and Zeolitis on morphological and biochemical indicators of rat's blood under conditions of experimental fumonisin toxicosis

In the article the peculiarities of the influence of fodder additives HammecoTox and Zeolit on the organism of rats under conditions of experimental chronic fumonisin toxicosis are given. The research was carried out under vivarium of State Scientific-Research Control Institute of Veterinary Medicinal Products and Feed Additives. In the experiment, 40 rats of body weight 165–170 g. were used. 4 groups were formed. First group of animals was control, in experimental II, III, and IV groups of animals chronic fumonisin toxicosis was reproduced. Rats were injected intragastrically daily of 90 mg of fumonisin per animal. After the manifestation of clinical signs of fumonisin toxicosis on the 21st day, animals of groups ІІІ-ІV began to feed fodder additives, respectively, rats from group III – HammecoTox, IV – Zeolit. After injection of fumonisin to experimental rats, the morpho-functional state of animals has been gradually changing since the first days. Clinical picture of fumonisin toxicosis in experimental rats at day 14 was manifested by dermo-necrotic effect, it was observed redness and formation of crust on visible mucous membranes, nose, showed swelling and redness of the forelocks. After the analysis of the obtained results of hematological researches on the 14th day in rats of group II under the conditions of experimental fumonisin toxicosis, was revealed a probable increase in the number of leukocytes, was established a tendency for growth, the number of eosinophils, segmental neutrophils, as well as a decrease in the number of lymphocytes, monocytes, compared with the control group. In the analysis of leukograms was noted a tendency to shift the nucleus to the left. These results indicated the presence of inflammatory processes and reduced immune protection of the organism of animals in general. After using of feed additives of HammecoTox and Zeolit under conditions of fumonisin toxicosis, of particular note is the stabilization of hematological parameters, the content of hematocrit, the number of leukocytes, the increase in the content of eosinophils and lymphocytes, which reflects the activation of hematopoiesis in the organism of experimental animals and its protective factors. An increase in the urea content in these groups indicates the recovery of urea-synthesis and urea-excretory liver function. In general, for the period of the conducted searches, the effectiveness of both feed additives in the experimental fumonisin toxicosis has been established. However, it should be noted that more active processes of normalizing the clinical condition of experimental rats when using HammecoTox, which is due to the complex influence of the means on the organism of animals.

Порівняльна оцінка препаратів фенбендазолу за інвазії курей-несучок нематодами Heterakis gallinarum

The article presents data on the effectiveness of two fenbendazole-based drugs for oral application: «Feboral» (in the form of a solution) and «Brovadazol 20%» (the reference drug in the form of powder). For this purpose, 420-day-old chickens were examined by a flotation coproscopic method in order to detect intestinal invasions. The therapeutic efficacy of the drugs was determined according to the data of the coproscopic examinations carried out using the modified quantitative McMaster counting method. The study of the efficacy of «Febboral» and «Brovadazol 20%» preparations was performed under the conditions of vivarium of the State scientific-research control institute of veterinary medicinal products and feed additives.During the experiment birds of experimental groups used preparations on the basis of fenbendazole: hens of the first experimental group, the drug «Feboral» was poured out with water (1.0 ml of the preparation for 10 kg of b. w., twice for two days), the second – the drug «Brovadazol 20%» they were given with food (0.5 g of the preparation at 10 kg b. w., for five days). Birds in the control group were given water and food without the contents of drugs.According to the results of research in hens were found invasion by Heterakis galinarum. The average rate of invasion of hens by nematodes during treatment with drugs was 176 eggs per 1 g of litter. In the hens of the first and second experimental groups, the average intensity of the helminth infestation on the seventh day of the experiment was 84.5 eggs per 1 g of litter, while the intensity of the infection of the control group was 211 eggs per 1 g of litter. On the fourteenth day of the experiment, the excretion of eggs from the pathogen in the hens of both experimental groups was not noted, while in the hens of the control group, the intensity of the invasion amounted to 238 eggs heterakis in 1 gram of litter.Consequently, the extenseffectivity of the drug «Febboral» and the reference drug «Brovadazol 20%» for heterakoses of chickens was 100%.
