Application of cause-and-effect relationships on support strategic decision-making in radioactive waste management in Ukraine
(3V Wydawnictwo Naukowe, 2024) Yeremenko, Sergiy; Sydorenko, Volodymyr; Mishchenko, Igor; Mezentseva, Iryna
The accumulation and storage of large-scale radioactive waste (RAW) in Ukraine poses a serious threat to the environment. Approximately 2500 tons of nuclear fuel waste was generated during the operation of the RVPK-1000 reactors. About 2800 tons of RW are materials containing nuclear fuel, including reactor graphite, fuel dust, etc. Objectives: The study is aimed at finding the most rational processes for managing accumulated and newly generated radioactive waste. Methods: To resolve complex, poorly formalized problems, system analysis provides the best efficiency. In the current study, an attempt was made to apply exactly this method to the management of radioactive waste. Results: The problem of RW management is complex and requires consideration of numerous factors. The initial basis, should be a functional approach. That is, the representation of the entire system through functional subsystems – groups of objects on which they behave with RW, and the subsequent division of each of the functional subsystems into further subsystems according to the types of accumulated and generated RW (aggregate state, activity level, radionuclide composition, etc.), which in turn is divided into elements. Conclusions: Proposed conceptual model structures the RW management system with all the variety of objects – sources of RW generation, types of RW and types of activities with them in separate subsystems – stages of RW management from their generation to disposal, and thus allows to significantly reduce the number of directions necessary for safety regulations in adoption of solutions.
Problems of occupational injuries and ways of its reduction on example of Ukraine
(Universitas Islam Negeri Alauddin Makassar, 2024) Mezentseva, Iryna; Vambol, Sergij; Kuzmenko, Olena; Osmanova, Olga
Manuscript presents a study of the causes of accidents on the example of Ukraine in recent years, considering the peculiarities of the modern period. The relevance of this study is due to the high level of industrial injuries in Ukraine compared to the industrialized countries of the European Union. Data on the dynamics of the causes of accidents for the period from 2015 to 2022 are presented. Data for the study were taken from open sources of information. The most trauma-dangerous industries of the national economy are considered. Proposed measures to reduce the level of injury in Ukraine. The analysis of the obtained results showed a certain dependence of the causes of accidents on the coronavirus infection. An unchanging leading position in the organizational causes of accidents has been established. According to the results of the study, regularities were established regarding the most traumatic sectors of the economy in the presented years. The predominance of organizational causes of industrial injuries due to the low motivational component of occupational safety is shown. The need to improve training on occupational health and safety issues for employees at all levels was noted. It was established that the reduction of industrial injuries is impossible without the teaching of labor protection issues in institutions of higher education by future heads of structural divisions and leading specialists. Mandatory review and re-approval of the instructions, the violation of which led to an accident, is proposed. It is recommended to apply mandatory professional selection and more thorough control over periodic preventive medical examinations.
Analysis of a City’s Heat Island Effect on the Micro-Climate Parameters within Cities
(Pakistan Academy of Sciences, 2023) Sharma, Rishabh; Amadur Rahman, Khan; Tyshchenko, Vasyl; Illiash, Oksana; Mezentseva, Iryna
The Urban Heat Island (UHI) is a micro-climatic phenomenon that influences the urban areas by elevating its temperature. UHI not only causes the thermal discomfort but also exert serious health issues along with aggravation of urban microclimate. Although a lot of research has been done on this phenomenon but UHI effect on micro scale is still less explored. This paper attempts to make a contribution in UHI studies of micro-climate. It consists of examination of UHI impact on microclimate of Aligarh city areas using mobile traverse method. This study determined the presence and extent of UHI’s microclimate variation within urban communities of different environmental layout and functional uses. The UHI effect started to appear from early afternoon and continue to rise with maximum UHI intensity recorded at early night. The highest recorded UHI intensity was 3.1 °C (at 21:00 hrs.), and the lowest was 0.6 °C (at 09:00 hrs.). A comparison of two districts of the same city located at a distance of 3 km and differing in population density, the number of buildings and landscaping showed that in the L1 area with more dense population and low landscaping, the temperature was consistently higher during the daily period; also the L1 region had less humidity, which combined with the already high temperature, makes it difficult to breathe and control the microclimate. These findings can be used for consideration for the future sustainable development of the affected area in regard of thermal comfort, environmental health and urban planning.
Determination of fat-soluble dyes influence on the oxidation induction period of their oil solutions
(PC Тесhnology сеntеr, 2023) Petik, Pavlo; Stankevych, Serhii; Zabrodina, Inna; Zhulinska, Oksana; Mezentseva, Iryna; Haliasnyi, Ivan; Hontar, Tatyana; Shubina, Lidiia; Kotliar, Oleh; Bondarenko, Svitlana
The object of the study is the period of induction of accelerated oxidation of oil solutions of fat-soluble dyes chlorophyll and beta-carotene. The effect of the content of fat-soluble dyes on the period of induction of accelerated oxidation of their solutions in refined sunflower oil was studied. The peculiarity of the work consists in establishing approximate graphic and mathematical dependences of the term of the induction period of accelerated oxidation of refined sunflower oil on the content of chlorophyll and beta-carotene separately and together. This is important for predicting the shelf life of oil solutions of fat-soluble dyes. It was determined that chlorophyll A practically does not show a pro-oxidant effect if its content is up to 0.05 g/l. The content of chlorophyll A at the level of 0.10 g/l leads to a reduction in the duration of the induction period by 14 %; 0.20 g/l – by 36 %; 0.30 g/l – by 48 %. The content of beta-carotene at the level of 0.10 g/l leads to an increase in the duration of the induction period by 35 %; 0.20 g/l – by 47 %; 0.30 g/l – by 54 %. The content in the oil system of 0.10 g/l of beta-carotene and 0.05 g/l of chlorophyll A leads to a reduction in the period of induction of accelerated oxidation by 8.4 % compared to the oil solution of 0.10 g/l of beta-carotene without chlorophyll A. The obtained data are explained by the fact that there is a compensatory effect of the antioxidant beta-carotene on the pro-oxidant effect of chlorophyll A in the oil solution. A feature of the obtained results is the possibility of predicting the shelf life of oil solutions of fat-soluble dyes. From a practical point of view, the results of the research allow to develop oil systems taking into account the separate and compatible features of reactivity to the oxidation of chlorophyll and beta-carotene. An applied aspect of using the scientific result is the possibility of expanding the assortment of oil products of increased nutritional value with different contents of chlorophyll and beta-carotene.
Development of safe technology of obtaining fatty acid monoglycerides using a new catalyst
(ПП "Технологічний Центр", 2022) Bliznjuk, O. N.; Masalitina, N. Yu.; Mezentseva, Iryna; Novozhylova, Tetiana; Korchak, Mykola; Haliasnyi, Ivan; Gavrish, Tatiana; Fomina, Iryna; Khalil, Viktoriya; Nikitchenko, Olga
Fatty acid monoglycerides are a valuable component of the products of various industries. The emulsifying ability of monoglycerides is used in cosmetic, pharmaceutical, and food production. The process of fatty acid monoglycerides obtaining by the reaction of vegetable hydrogenated fat (salomas) with glycerol (glycerolysis method) has been studied. Potassium glycerate is used as a catalyst, which is characterized by high efficiency and safety of production and use. A feature of the work is the study of the dependence of the yield and melting point of monoglycerides on the technological parameters of glycerolysis. As a raw material, hydrogenated refined fat according to DSTU 5040 (CAS Number 68334-28-1) was used: melting point – 48 °C, mass fraction of moisture and volatile substances – 0.08 %, acid value – 0.25 mg KOH/g, peroxide value – 2.8 ½ O mmol/kg. In all experiments, the glycerolysis temperature was 180 °C, the catalyst concentration – 0.5 % in terms of metal. Rational conditions for glycerolysis were determined: duration (90 min.) and glycerol concentration (50 %). Under these conditions, the monoglycerides yield was 32.9 %, melting point – 61.5 °C. The mass fraction of free glycerol in monoglycerides was 1.0 %, acid value – 2.2 mg KOH/g. The efficiency of monoglycerides obtaining using potassium hydroxide and glycerol mixture as a catalyst under certain rational conditions has been studied. The monoglycerides yield of 30.1 %, melting point of 59 °C were obtained. Therefore, the use of potassium glycerate catalyst is more efficient. The results of the study make it possible to improve the technology for the production of fatty acid monoglycerides using a new catalyst and use resources rationally.
