At the same time the peculiarities of the formation and modeling of a complex heterogeneous stratified structure of a biofilm with variable processes and parameters along its thickness are considered and taken into account on in particular the processes of mass transfer and concentration of microorganisms. It shown that the treatment processes in heterogeneous stratified biofilm are designated by the effective diffusion coefficient which is depended on the pollutions concentration. Owing to that the pollutions concentration is changing of along the biofilm thickness and increase from the surface to the biofilm bottom the decreasing of the effective diffusion coefficient is observed. On the base of the provided experimental investigations the change of the effective diffusion parameter along the biofilm thickness may be specified according to linear law. The quantity criteria of the first and zero order kinetic and Monod equation were used in the practical calculations. Ascertain that the substrate removal have a place on the early part of the biofilm which amounts to 20–25% from the its full thickness. On the base of the created biofilm model of the heterogeneous-stratified structure the comparative analysis and valuation of the different investigations of the pollutions removal during the treatment processes at using of the homogeneous and heterogeneous structure of the biofilm were treated. It was designated that the pollutions removal effectiveness depends on the biofilm features. So at the some main parameters the homogeneous and stratified biofilms indicate almost the same microbial activity and the difference depends on the effective diffusion coefficient on the biofilm output. In the dependence on the hydrodynamic conditions of the treatment processes the homogeneous biofilm activity may be lower, higher or similar one of the stratified biofilm. Heterogeneous biofilm has the lower activity near the biofilm bottom at the high values of the effectiveness coefficient than the homogeneous one at the average values of this coefficient and the substrate against of the which the microorganisms growth is depended on to penetrate more in depth in stratified biofilm than in homogeneous one.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the issue of determining the level of nuclear and environmental safety of Ukraine's nuclear power plants in extreme war conditions, using the example of the situation that developed at the Zaporizhzhia Nuclear Power Plant (ZNPP), the largest in Europe, is extremely urgent, precisely because of the station's location in the war zone.During the period of the full-scale war, there have already been dozens of warheads hitting the objects of the critical infrastructure of the ZNPP, the external and emergency power supply of the ZNPP (transformer equipment, power supply systems to consumers, the premises of diesel generators, the industrial site of the station, and others). There have been corresponding emergency shutdowns of the power units of the ZNPP due to the blackout of the station and due to the forced disconnection of consumers as a result of the destruction of various objects in the power grid systems. These events cause great alarm and concern of the world public regarding the possibility of new global nuclear-ecological disasters due to nuclear-radiation accidents at the ZNPP. Many years of global experience in the operation of nuclear power reactor facilities (NPRF) and their safety regulation, as well as lessons from the largest nuclear and radiation accidents at NPPs, have revealed the insufficient validity of traditional probability indicators and safety criteria for NPPs, including the Zaporizhzhya plant. Probabilistic approaches to assessing the objective level of safety of the Zaporizhzhya NPP in extreme conditions of war are insufficiently substantiated, taking into account, among other things, the need to predict the possibility of the occurrence of unlikely emergency events and their combinations, which will have catastrophic consequences.Therefore, conducting an objective assessment of the level of nuclear and radiation safety at the ZNPP due to the station's location in the war zone, as well as substantiating practical recommendations for preventing nuclear and environmental disasters at the NPPs of Ukraine, is an extremely urgent issue for the entire nuclear energy industry of Ukraine.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It stimulates the development of new graph based stream ciphers. It turns out that such encryption instruments can be efficiently used in GIS protection systems which use N-Tier Architecture. We observe known encryption algorithms based on the approximations of regular tree, their modifications defined over arithmetical rings and implementations of these ciphers. Additionally new more secure graph based ciphers suitable for GIS protection will be presented.Algorithms are constructed using vertices of bipartite regular graphs D(n,K) defined by a finite commutative ring K with a unit and a non-trivial multiplicative group K*. The partition of such graphs are n-dimensional affine spaces over the ring K. A walk of even length determines the transformation of the transition from the initial to the last vertex from one of the partitions of the graph. Therefore, the affine space Kn can be considered as a space of plaintexts, and walking on the graph is a password that defines the encryption transformation.With certain restrictions on the password the effect when different passwords with K*)2s, s <[(n+5)/2]/2 correspond to different ciphertexts of the selected plaintext with Kn can be achieved.In 2005, such an algorithm in the case of the finite field F127 was implemented for the GIS protection. Since then, the properties of encryption algorithms using D(n, K) graphs (execution speed, mixing properties, degree and density of the polynomial encryption transform) have been thoroughly investigated.The complexity of linearization attacks was evaluated and modifications of these algorithms with the resistance to linearization attacks were found. It turned out that together with D(n, K) graphs, other algebraic graphs with similar properties, such as A(n, K) graphs, can be effectively used.The article considers several solutions to the problem of protecting the geological information system from possible cyberattacks using stream ciphers based on graphs. They have significant advantages compared to the implemented earlier systems.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the influence of a tense state, they are similar to gills. Stress concentration zones in areas of irregularity have a significant impact on the tensile strength and durability of thin-walled structures. Traditional analytical and numerical methods known at this time are less effective in investigating the stress-strain condition of corrugated thin-walled structures. It is, therefore, necessary to develop new effective methods for solving the tasks of this class. Currently, for engineering calculations, there is virtually no comparison of simple and convenient formulas for determining the critical compressive load taking into account the peculiarities of the design. The scientific novelty of the paper is that to achieve the set goal, it will be used for the first time in the general theory developed for the calculation of buildings and structures, known as the \"Theory of elasticity in ordinary differential equations.\" The paper will show that the accuracy of this new theory is adequate to the classical elongation theory and at the same time dramatically simplifies the solution of any problem in the calculation of tiles, which is achieved by converting them to conventional differential equations. The general methods of compiling differential equations, the methods of its simplification, for the calculation of membranes with cross-sectional incisions, and the calculation of plates under conditions of nonlinear deformation are discussed. Methods for solving differential equations with variable and momentum coefficients are specified. An algorithm and a program for the analysis of the stress-strain state of spatial structures and their elements are developed. The practical value of the paper lies in the possibility of using developed methods and programs for the design and construction of buildings, as well as for the stability tasks of slabs with holes, and panels used in construction as typical assembly elements. The given mathematical algorithm and program for specific tasks, which are distinguished by simplicity, can be used by design and research organizations in the calculation and design of plates and membranes.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CO2 recycling has emerged as a promising solution, aiming to convert CO2 into valuable products while reducing its impact on the environment. This work uses the CO2 recycling approach, which involves the conversion of CO2 emissions into useful organic compounds. An experiment with artificial photosynthesis is carried out with the help of a special installation, where CO2 undergoes photochemical reactions that contribute to the formation of organic compounds. Photocatalytic conversion of CO2 is environmentally friendly as it uses light energy and renewable raw materials to produce valuable chemicals without producing harmful by-products or waste. It has been established that TiO2 in the form of anatase and rutile is the most common CO2 photocatalyst. As a result of the experiment, the main output products were methanol, acetate aldehyde and acetone. The use of ultraviolet radiation and an electric field significantly affected the synthesis of organic substances and their quantity. It can be used in various industries such as fuel, chemical and pharmaceutical industries. In particular, methanol, acetate aldehyde and acetone are promising substances for the use and production of biofuels.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effectiveness of the use of space survey materials for the study of soil cover largely depends on the time of the survey. The linear forms of erosion (waterholes, ravines) are deciphered on space photographs, which are displayed only on images with a spatial resolution of 1-2 meters in the form of narrow, clearly delineated contours that have a jagged shape.The developed clustering algorithm makes it possible to more clearly identify beam structures on satellite images in combination with data from digital terrain models (DRM). A number of experiments were conducted on some set of remote sensing data of Boryspil and c. Panchevo, Novoukrainsky District, Kirovohrad Region. The experiments consisted in determining the spectral and other features of the beam structures (for example, the shape, soil types, etc.), which are located in different places of the territory that was investigated.On images with a spatial resolution of more than 10 meters, ravines are usually not displayed, but networks of beams with elongated wavy tree-like shapes are clearly visible. In the course of the study, data from multispectral imaging from the Sentinel-2 satellite (MSI scanner) and DEM (Digital Elevation Model, DEM) data obtained through the SRTM 3 archive were used.The research results showed that automating the process of highlighting beam structures on multispectral images with a spatial resolution of 30 m is very difficult. First of all, this can be explained by the fact that the beam consists of vegetation that is also present outside the beam.

Therefore, it is necessary to move to the concept of combining living plants with building structures. The concept of green construction is a universal approach that allows not only to reduce the negative impact of construction on the environment but on the contrary, to ensure a positive impact on the environment. This concept can be applied at all levels – from a single building to neighborhoods or settlements. One of the serious problems of cities is the management of stormwater runoff. They carry trash, bacteria, heavy metals and other pollutants through storm drains into local waterways. The most common means of managing urban runoff are storm sewer systems, which have the conventional name of \"grey infrastructure.\" These systems are ageing and require expensive repairs. Due to climate change, the amount of runoff is increasing, which leads to exceeding the carrying capacity of the systems. The development of territories significantly disrupts the water balance. The sponge city allows effective solving of these problems thanks to the maximum approach of the functioning of built-up areas to unbuilt ones. In this work, a \"green\" roof is being developed on the roof of the \"Perekhrestia\" shopping and business center in Dnipro city. To do this, the volume of precipitation in the city for 2022 was analyzed. The \"Roof Garden\" system from the Zinko-Ukraine company was adopted. This system currently has a margin of 50% retention of precipitation falling on green areas. To dispose of water from pedestrian areas, it is necessary to install water storage tank(s). It is advisable to use this water for watering green areas or for toilet needs. Two toilets in the public toilet ensure the emptying of the tank(s) in 15 days. Increasing the number of sanitary devices simplifies the water supply system and increases the resilience of objects to climate change.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The essence of the method is to identify the internal structure of the code, due to which the structure of the component codes of the turbo code is determined. It was developed using the gradient method due to the implementation of a multi-step iterative procedure for finding optimal system parameters. Implementation of the method allows to ensure the reliability of information transmission of wireless data transmission systems. To check the effectiveness of the method of structural adaptation of cascade codes, a simulation model was developed in the C++ programming language in the Visual Studio 2019 software environment, and wireless data transmission systems were simulated. The simulation results show that the combined structure of building cascade codes together with OFDM technology allows you to independently adapt the coding rate of each of the coding stages depending on the results of the analysis of the reliability of information in this cascade, which leads to the provision of the specified reliability of information transmission, while the BSPD bandwidth is reduced by 4–12% against 20–35% of known results. The use of Reed-Solomon codes in a sequential cascade scheme with turbo codes due to the adaptation of the coding rate of this cascade design allows obtaining an energy gain of 0.5–0.7 dB without increasing the bandwidth of the transmission system compared to systems that use only turbo codes. The obtained results are of significant relevance and can be implemented in the development of information transmission systems to ensure the reliability of data transmission, both in peacetime and in conditions of armed aggression of the Russian Federation against Ukraine.","PeriodicalId":313972,"journal":{"name":"Environmental safety and natural resources","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139334423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
