Authors: Semenova Yu , Kendzera O , Skurativskyi S , Mykulyak S , Skurativska I , Topoliuk O 
Published: December 2024

Abstract
This research addresses the imperative task of effective disaster mitigation planning for significant earthquakes, specifically focusing on the Shamkir-Mingachevir reservoir region. The complexities of seismic risk assessment involve the intricate interplay of geological, geotechnical, and environmental factors. The character of propagation of seismic waves is influenced significantly by local site conditions, shaping the observed intensity of ground motions at the surface. The term “site effects” is central to this research, signifying the amplification of seismic waves influenced by distinctive geological conditions. The results indicate that soils with lower shear wave velocities exhibit lower peak ground accelerations at the surface. However, the study highlights the susceptibility of softer soils to nonlinear effects, emphasizing the need to consider the composition of local soils in developing seismic safety measures. The separate study of resonant frequencies of the soil-structure system is crucial to mitigate resonant effects during earthquakes. This approach facilitates the development of accurate and tailored building standards aimed at safeguarding infrastructure and ensuring safety in seismic zones.
Evaluation of the green flood mitigation measures in urban area in the frame of the sustainable city concept
Authors: Velychko S V , Dupliak O V 
Published: December 2024

Abstract
The flood protection problem has always existed for the Ukrainian Carpathians. The floods that caused damage to urban areas occurred 10 times during the past 20 years in the basin of the Uzh River, ones were the cold period floods in most cases. The Uzh River passes through the central part of the Uzhhorod city, the river is crossed by five bridges, the embankment consists of “grey” flood protection structures: dams, concrete and stone walls. The central embankment was flooded by extreme floods only. At the same time auxiliary buildings and greenhouse in the Botanic Garden and the Bozdos Park area are flooded almost every two-three years. The purpose of the work is to update hydrological calculations, to calculate the flood water surface curve and assessment of the “green” flood mitigation measures in the central part of the city. Flood flow rate of 1% probability was calculated by processing continuous observations data for 72 years. Flood water levels of 1% probability were calculated using a 1D HEC-RAS model. Retention reservoirs, old river bed, mobile flood protection systems for local areas and buildings were considered as “green” flood control measures. Relocating embankments to make “room” for river within the existing buildings is not possible, but some stream widening has been preserved within the Botanic Garden by local flood protection of the single buildings and the central part of the garden. Calculation showed that the central part of the city is protected from flooding by the existing dykes, except for a few areas that would be protected by local mobile barriers. It is not possible to create an exclusively “green” flood control measures in the urban area, but the further development of flood risks management must be directed to the concept of a sustainable city development with minimization of the negative environment impact.
Stakeholders’ awareness and perception of bio-economic transformation in Ukraine
Authors: Vostriakova V I 
Published: December 2024

Abstract
Existing bio-economic strategies are complex political documents that affect all spheres of human life, nature, and the economy and require broad social perception. Despite Ukraine’s high bio-economic potential, this term has yet to enter the everyday lives of both politicians and ordinary citizens. The vision of what positive or negative consequences this concept generates and what conflicts and political demands may be associated with it has yet to be accurately formed. The article explores the micro-level perception of bio-economic transformation by critical stakeholders to support policy and strategy development at all decision-making levels. We used quantitative data from surveys in three target groups of respondents (scientific and innovation sector, business and industry, government and non-government organizations) to form an approximate picture of the bio-economic transformation perception from scientific, public, and business perspectives. According to the results, bio-energy and agriculture are considered the sectors of the bio-economy with the highest potential for growth in Ukraine. Respondents of all target groups are united in the understanding that the state bears greater responsibility for communicating and promoting the bio-economy among a broader audience, which is not sufficiently informed about potential advantages and problematic issues. The advantages of bio-economic transformation for the environment are perceived as undeniable. Potential risks are minimized or not perceived as such. The understanding of the role of bio-economic transformation in economic growth, job creation, innovation development, and digitalization is less visible. Almost 20 percent of respondents believe that the problem of insufficient biomass for bio-economic transformation is the most critical risk. Biomass as a raw material of sufficient quality may have other options for creating products with high added value before being used in bioenergy at the end of its life cycle. The risks of insufficient biomass can be partially reduced due to the widespread implementation of the cascade use of biomass and the principles of the circularity of the bio-economy. Thus, it is vital to include circularity, cascading use of biomass, and aspects of the rational resources used in the communication policy of bio-economic transformation, as well as its synergy with the main bio-economic sectors regarding the use of biomaterials and innovative knowledge and technologies with their undeniable positive impact on mitigation climate change. The results of the bio-economy perception survey can be used by stakeholders when developing or revising communication strategies and plans and fill a scientific gap in the perception of bio-economic transformation by various stakeholders in Ukraine.

Increase in the energy efficiency of the biogas production process through vibration activation of heat and mass exchange processes in the bioreactor
Authors: Dzhedzhula V V , Yu Yepifanova I 
Published: December 2024

Abstract
One of the important problems preventing the increase in energy efficiency of biogas reactors is the use of heating elements operating in the free-convective mode of heat exchange. In addition to the large heat exchange areas, and the correspondingly reduced useful volume of the reactor, the use of free convective heat exchangers leads to the formation of stagnation zones, stratification of the medium, hypocooling of the lower zones of the reactor, overheating of the upper zones. The intensification of the heat exchange between the heating element and the substrate will allow to reduce the area of the heat exchange devices in the reactor, activate the thermostabilizing processes and reduce the cost of the reactor construction. Based on the results of the analysis of the influence of the fluid oscillation created by the movement of the activator plate on the intensity of heat transfer from the heating wall to the water and the substrate, the choice of the determining temperature of the liquid and the temperature of the wall with different methods of organizing convection is substantiated.

Authors: Valovoi O I , Eremenko O Y , Valovoi M O , Volkov S O 
Published: December 2024

Abstract
One of the main development programs of each country is the control and utilization of industrial waste since the sustainable development of this industry is accompanied by the greatest environmental pollution. Iron ore beneficiation byproducts are artificial quartz-iron mineral mixtures that are fed into sludge ponds that form the so-called tailings ponds in the form of pulp. Tailings ponds occupy more and more territory every year and have a significant negative impact on the environment. At the same time, industrial waste from iron ore enrichment, the so-called tailings, is used as a fine aggregate in concrete mixtures to replace quartz and construction sand. Studies show that a 40% replacement of quartz sand with fine iron ore dressing waste is optimal for the manufacture of concrete mixtures without any adverse effect on strength and durability properties. The paper considers the stress-strain state of beams in the second group of limit states made of concrete mixtures at 100% replacement of quartz sand with fine plant protection products waste. The percentage of reinforcement of beam sections of all series and the class of concrete were assumed to be the same for samples of all series. The results of experimental tests showed almost comparable results of crack resistance of beams reinforced with metal reinforcement and with hybrid reinforcement. At a load of 70% of the destructive capacity, BM and BMD beams do not exceed the maximum permissible width of normal crack opening, and BMBD beams do not exceed the maximum permissible width of 60%.

Authors: Saveliev S G , Yarosh T P , Kondratenko M M , Babaievska O V , Yu Baboshko D 
Published: December 2024

Abstract
The article is devoted to the urgent problem of utilisation of red mud (RM) – a by-product of bauxite ore processing in the process of aluminium production. The acuteness of the problem is increased by the negative influence of red mud on the environment due to its high alkalinity of its pulp (pH = 9-12) and fine dispersibility. The article characterises the main properties of RM, reveals the essence of the most effective method of its storage today – dry stacking. Due to the presence of high content of iron oxide and such metals as Al, Ti, Y, Ce, etc. in the composition of RM, it is a valuable complex man-made raw material. The analysis of modern technologies of RM processing has shown that the important tasks in its utilisation are the processes of dehydration and disinfection. The first one is most successfully solved by using filter presses, the second one – by adding lime to the sludge washing system. Technologies for extraction of valuable components from RM can be divided into two groups – pyro- and hydrometallurgical. The most promising solution to the problem of effective integrated waste-free processing of RM is a rational combination of these two processes.

Published: December 2024

Abstract
The production of vegetable and melon crops is one of the most labour-intensive branches of agricultural production. Production volumes depend not only on growing conditions, but also on the quality of seed material. A resource-saving method of extracting cucumber and melon seeds and a separator that allows its implementation are presented. The design feature of the separator is a combination of vibration and inertial modes. The use of a separator, which has a combination of the mentioned modes in the technological process, allows to significantly improve the quality of separation of seeds from the peel and pulp. Thus, at the next stage, when washing the seeds, it is possible to reduce the amount of water, using the technology of a complete closed cycle of cleaning for reuse. The scheme of the technological process of cucumber and melon seed separation, which is used to implement a resource-saving method, is presented. The main factors and optimization criteria were determined, according to which the quality assessment of the technological process of cucumber and melon seeds separation was carried out using the proposed constructive solution. The ranges of the optimal combination of independent factors are determined. Using a resource-saving method of extracting cucumber and melon seeds allows to significantly reduce water consumption when washing seeds and achieve an improvement in the quality of the technological process.

Published: December 2024

Abstract
Plant-based dairy alternatives have been gaining popularity recently in developing nations, but only a little is known about the consumer perception of these goods. This study aims to analyze the key determinants that affect millet milk consumption in India. An online survey was conducted with a sample of 178 people belonging to different age groups and educational backgrounds. Binary logistic regression was used in the study to analyze the factors that will significantly contribute to the consumption of millet milk. The results suggested that veganism and ethical concerns significantly affected decision-making. In addition, the educational background of the people was also significant but negatively correlated in influencing the consumption of plant-based dairy alternatives. The study aligns with SDG 12: Sustainable Consumption and Production, SDG 13: Climate Action, and SDG 3: Good Health and Well-being, contributing valuable insights for fostering sustainable dietary patterns and environmentally conscious consumer behavior. To promote millet milk in the Indian market, the stakeholders can customize their marketing strategies and emphasize ethical concerns and veganism.

Abstract
In the paper showing A U-Net-type convolutional neural network proposed for vegetation segmentation in multispectral imagery. The architecture of this network has modified and expanded to achieve better results with a smaller training dataset. The use of the network has made it possible to improve the solution to the problem of accurately identifying objects from the background based on existing information without the use of additional means of obtaining data. The processing of images of a corresponding nature is shown for 4-channel multispectral satellite images using a U-Net-shaped network trained on aerial images. Preprocessing showed the need to take into account the image formation model and perform post-training of the network based on the obtained data. A comparison conducted between the results of vegetation zone delineation in multispectral images using a convolutional neural network with a modified U-Net-like architecture and the Normalized Difference Vegetation Index (NDVI). The NDVI vegetation index uses data from various spectral channels and calculated as the ratio between intensities in the red and near-infrared channels of multispectral imagery, displayed as a number from -1 to +1, where a higher index value signifies denser green vegetation. Shown that for acceptable results, it is enough to use 4-channel images (NIR+RGB). The simulation performed in the MATLAB system.

Published: December 2024

Abstract
The article presents designe of rapid-hardening, non-shrinking cementitious mixtureses, which allows solving the problem of rehabilitation of concrete structures and has a positive effect of environmental sustainability. To ensure the maximum dense packing of the cement mixture, the granulometric composition of the sand was optimized. Mathematical models of physical and technical indicators of repair mixtures based on Portland limestone cement and optimized sand composition were obtained, which quantitatively characterize the action of high-alumina fly ash, sodium hydroaluminate, polycarboxylate ethers with increased rapid hardening, early strength, adhesive strength and reduction of shrinkage deformations. A combination of Portland limestone cement, fly ash, polycarboxylate ethers and alkaline activator ensures the intensification of early structure formation due to the formation of hydrocarboaluminates and alkaline hydroaluminosilicates; larger fractions of limestone particles and fly ash act as a microfiller, which in the complex contributes to increasing the early strength and stability of the cementitious matrix.
Collapse behaviour of double-layer pipes: A review
Authors: Imannuaji R I , Adiputra R , Prabowo A R 
Published: December 2024

Abstract
Pipes serve as crucial conduits for fluid transportation across diverse industrial sectors, necessitating a thorough understanding of their structural properties and performance under varying conditions. This study explores the resilience of underwater double-layer pipes, comprising inner and outer layers separated by an annulus that usually used in deep water application such as OTEC and gas and oil transport, against collapse induced by bending moment loads or external pressure. The investigation encompasses a comprehensive review of relevant literature and examines different configurations of DLP. The analysis reveals that key factors influencing the buckling capacity under pure bending loads include pipe length, core thickness ratio, and core stiffness. Under hydrostatic pressure, collapse behavior is influenced by the radius-to-thickness ratio and the ratio of the core thickness to outer and inner layer thicknesses. Furthermore, the collapse mechanism of the double layer pipe is analyzed. The study underscores the importance of addressing such structural nuances in design and operational considerations.
