Ever-growing concerns and governmental restrictions related to the use of pesticides in modern agriculture has driven the need for more adept decision-making tools to minimize unnecessary treatments whilst still efficiently preventing a spread of infection. To this effect, a network of cost-effective, laser-based holographic detectors were developed and placed in vineyards in Switzerland and France with the objective of detecting and identifying airborne spores of downy and powdery mildew before they have the potential to infect crops. The data collected are remotely sent to a server where image processing techniques and artificial intelligence classify the spores and determine the quantitative intervention thresholds. Knowledge on the quantitative development of fungal diseases has been successfully used to temporally and spatially identify the primary infection of downy mildew which was confirmed by a visual evaluation of symptoms within the parcel. This data coupled with the current risk prediction models provide farmers with a powerful decision-making tool to optimise strategies in the management of grapevine diseases.
Kaolin foliar-application improves the photosynthetic performance and fruit quality of Verdejo grapevines
Authors: Azuara Marie , González María-Rosa , Mangas Rafael , Martín Pedro
Published: December 2023

Currently there is an urgent need to adapt vineyards to climate change in order to maintain and improve the quality of wines. In this context, it has been shown that the creation of a film of mineral particles, such as kaolin, on the vegetation can reduce stress caused by high temperatures in plants. The present study evaluated the effects of kaolin foliar-applications, from fruit set to veraison, on the physiological and agronomic behavior of a Verdejo white variety vineyard located in DOP Rueda (Spain). Compared to the controls, treated plants showed an increase in the photosynthetic performance, registering higher values of chlorophyll fluorescence parameters such as Fv/Fm, ΦPSII and ETR, and lower values of F0. Without affecting vigor and yield, grapes from treated vines produced musts with lower pH and phenolic content and greater color luminosity than those of untreated vines. The presented results suggest that kaolin treatments could be an effective tool to minimize the negative effects of climate change on the quality potential of white grape varieties grown in continental areas.

Published: December 2023

Los vinos de crianza biológica producidos en el sur de España (Jerez-Xères-Sherry; Manzanilla de Sanlúcar, Montilla- Moriles and Condado de Huelva) son productos de elevada calidad reconocidos en todo el mundo. Estos vinos, denominados Finos y/o Manzanillas, son fortificados usualmente hasta los 15%-16% v/v alcohol para llevar a cabo la etapa de crianza bajo velo de flor que los caracteriza. El modelo de consumo de vino está cambiando y los consumidores buscan productos de elevada tipicidad y calidad sensorial, pero con una graduación alcohólica moderada. En este sentido, sería muy interesante para el sector poder elaborar estos vinos, manteniendo su calidad, pero con niveles de alcohol algo más moderados (13,5-14,5% v/v). En el presente trabajo, se resumen los resultados más relevantes de la conducción de la crianza biológica, tanto estática como dinámica, con grados alcohólicos más bajos de lo habitual en tres bodegas del marco de Jerez, y trabajando en dos escalas diferentes. Además, se han realizado catas con consumidores para evaluar de manera preliminar la posible aceptación de estos vinos en el mercado. Los primeros resultados nos indican que es viable trabajar a un grado alcohólico algo inferior al habitual sin que ello afecte a la actividad normal de las levaduras del velo de flor ni a la calidad de estos vinos.
Is there a need to re-define the methods to evaluate wine color
Authors: Durner Dominik , Hensel Marcel
Published: December 2023

Both the Glories method and the CIE L*a*b*/L*C*h0 system are used in analytical protocols to expredd the chromatic characteristics of wine [1-4]. Both emthodes allow for the interpretation of color intensity, color hue, and other chromatic characteristics. They are utilized in scientific studies to compare experimental treatments and many innovations have been assessed on whether they could retain a higher color intensity or yield ore color brilliance. The validity of the two methods and the explanatory power of the respective color parameters were investigated by comparing the two methods with data from a sensory study. Data intervals from 0.5 to 5 nm and different scan speeds were tested as spectrophotometer settings. A trained panel evaluated 112 dark red, light red and white wines from different grape varieties, origins, and vintages. The correlation between Glories system and the CIE color space was found to be strong for dark red wines (r > -0.9). Lighter red wines and white wines (L* > 20) do not correlate with the same quality, except for the correlation between CI and L* (r > -0.9). In comparison with the human perception, the red and white wines could not be distinguished well with the Glories’ system. The CIE color space was found to be more suited to depict the perceived color for red and white wines. In recent years, the CIE re-defined the color distance calculation within the CIE L*a*b* color space due to non-uniformities. The CIEDE2000 color distance ΔE00 was proposed [4–6] for a better approximation of the erceived color than the Euclidean color distance ΔE*ab. A just noticeable distance (JND) test was carried out using triangle testing for the wines segmented into three wine color area: dark red, light red, and light yellow. For dark red wines, the JND was ΔE00 = 1.4 or ΔE*ab = 3.1, respectively. For light yellow wines, the JND was found to be much lower values at ΔE00 = 0.64 and ΔE*ab = 0.60. And for light red wines, the JND was found to be very high at ΔE00 = 3.4 or ΔE*ab = 8.1, respectively. The CIEDE2000 formula resulted in lower JND values than the Euclidean color distance. Although still not uniform for the huge diversity of wine colors, the ΔE00 provides better comparability and is suggested for future studies.

Published: December 2023

UHPH treatment of Vitis vinifera must for winemaking leads to fragmentation of colloidal particles into smaller structures. The shear and fracture forces experienced by grape juice during valve pressurization are sufficient to reduce the particle size of grape juice to below 500 nm. As a result, the applied force can disrupt bacterial and yeast cell structures, altering or breaking down proteins, polysaccharides and enzymes. This effect is not observed for low molecular weight compounds such as monomeric pigments and phenolic structures, varietal aroma precursors, fermentable sugars, etc. Treated and untreated samples can be compared using optical and atomic force microscopy. Optical microscopy images show reduction or elimination of bacteria and yeast and changes in microstructure. On the other hand, in addition to describing topography in the nanometer range, AFM can also measure particles in comparison to other techniques such as laser diffraction (LD). This work contributes to the characterization and better understanding of the effects of UHPH on grape juice for winemaking.
Investigation of using different specified yeasts and early protein stabilization for Tokaji dry wines
Authors: Bene Zsuzsanna , Kiss István
Published: December 2023

The use of special-purpose yeasts is becoming increasingly important in winemaking practice due to counterweight negative effects of climate change. There are no specified commercially available yeasts for most autochthonous grape varieties in the wine region of the world, just as in the case of Kövérszőlő, which plays an important role in the Tokaj wine region. The world's winemaking practices are increasingly shifting towards making new wines as quickly as possible in a given vintage, with a lower quantity, more conscious use of chemicals and minimising sulphurisation in the interests of sustainability. There are bentonite materials on the market with low-iron granulate that can be added to the must, removed with the lees at the end of fermentation and used to obtain a new wine with a clean smell and high purity of stable white must. In this study, different special yeast products of Erbslöh were tested in comparison with spontaneous fermentation in the important autochthonous variety Kövérszőlő. At the same time, the influence of simultaneous and early protein stabilization was analyzed. The aim was to explore the changes in analytics and sensor technology and the adaptation to the current market requirements.

Authors: Pino-Ramos Liudis , Laurie V. Felipe , Gómez-Plaza Encarna , Bautista-Ortín Ana B.
Published: December 2023

The wine industry has increased its interest in finding new fining agents, and vegetable proteins have received increasing attention. Quinoa and kiwicha are native pseudocereals to the Andean highlands with high protein content and are considered gluten-free products. This work aimed to determine the effect of fining with quinoa and kiwicha protein extracts (QP and KP respectively) at different doses (30 and 50 g/hL) on the aroma composition, color, and phenolics of a Monastrell wine compared to pea proteins and gelatin. Fining treatments produced no significant reduction of TPI. Except for QP at 30 g/hL and the lowest dose of pea proteins, the fining treatments decreased the content of total anthocyanins. The doses of 50 g/hL of QP and KP were particularly efficient, producing the largest decrease in total tannins. Analyses by size exclusion chromatography showed that treatments with QP and KP were capable of selectively removing high molecular weight phenolics. All fining agents slightly decreased the color intensity. All fining treatments showed a significant decline in total ester concentration (26-45%). Instead, total alcohols remained constant upon the fining treatments. Five terpenes were identified in all wines, and their content was not affected by the fining treatments.

Authors: González-Neves Gustavo , Favre Guzmán , Piccardo Diego
Published: December 2023

Este estudio resume los principales resultados de ensayos realizados en Uruguay con la variedad Tannat durante 25 años. Los vinos de este cultivar son emblemáticos del Uruguay. Tienen una gran tipicidad, con un color y composición polifenólica particulares. Se evaluaron distintas técnicas de vinificación, con el objetivo de mejorar la calidad de los vinos y mitigar los efectos del cambio climático. Las opciones evaluadas fueron: (I) empleo de enzimas de maceración, (II) maceración pre-fermentativa en frío, (III) extracción diferida de antocianos, (IV) maceración extendida, (V) extracción diferida de antocianos con maceración extendida, (VI) maceración pre-fermentativa en caliente, (VII) empleo de taninos enológicos. Los testigos de cada ensayo fueron vinos elaborados de manera tradicional (MT). La MPC fue la técnica que tuvo mayor impacto en el color y la composición fenólica de los vinos. Los contenidos de antocianos solamente fueron incrementados por la MPC y ENZ. Los contenidos de taninos poliméricos fueron incrementados muy significativamente por MPC, ME y la MPF. A su vez, los mismos tratamientos incidieron significativamente en los contenidos de taninos monoméricos. Los resultados obtenidos fueron diferentes según la técnica de elaboración, respondiendo a los objetivos procurados en cada caso, pero los efectos fueron distintos en cada año. Esto indica que el efecto de cada técnica está condicionado por el clima y su impacto en la composición de la uva.

Published: December 2023

El objetivo de esta investigación fue evaluar el efecto de la sustitución de mosto Tannat por mosto Ugni Blanc, sobre el contenido de alcohol, pH, color y composición fenólica de los vinos. Para ello, se realizaron vinificaciones por triplicado de mostos Tannat (VT) y mostos Tannat sustuidos con un 20% de mosto Ugni blanc (SM) en tres temporadas consecutivas. Se realizó un análisis climático de la región durante la maduración. Se evaluó la composición de la uva en cosecha y el color y la composición de los vinos a los cuatro meses del descube. Las características climáticas de las temporadas fueron contrastantes debido a la cantidad y distribución de las precipitaciones. Las uvas Tannat cosechada en el 2020 presentaron mayor concentración de azúcares, pH y riqueza fenólica. Las lluvias durante la temporada 2022 provocaron una mayor incidencia de Botrytis spp., afectando su potencial enológico. Los vinos SM presentaron menor contenido de etanol respecto a los VT. Los vinos SM y VT elaborados en la vendimia 2020, no presentaron diferencias en el pH, en tanto que para las demás temporadas los resultados fueron discordantes. La sustitución de mostos no afectó el color del vino, en tanto que las concentraciones de polifenoles totales, antocianos y taninos de los vinos SM fueron iguales o superiores a la de los vinos VT. La sustitución de mosto, parece ser una alternativa válida para la elaboración de vinos tintos con menos contenidos de alcohol, sin afectar negativamente su color ni su composición fenólica.

Soil management is a sustainable agronomic practice to produce grapes, wine, and grape pomace with a low environmental impact in viticulture, affecting soil microbial biodiversity, organic matter, and healthy roots. Grape pomace is the main by-product of winemaking and a valuable source of natural phytochemicals. This research aimed to evaluate the phenolic content and antioxidant activity of pomace deriving from the microvinification of the Primitivo wine grapes obtained by four different soil management techniques: cover crop (C), soil mechanical tillage (T), green manure (G) and farm soil management (F). The content of total phenolic compounds and anthocyanins in grapes and wines is the highest with the vineyard cover cropping system. Moreover, grape pomace derived by cover crop soil management shows a significant abundance of these molecules and a more elevated antioxidant activity than the other soil technique.

Published: December 2023

With the aim to obtain an ingredient rich in bioactive compounds to be used in meat products, a red grape pomace (RGP) cv. Tempranillo, was subjected to the application of different hydrostatic high pressure (HHP) treatments: i) 600 MPa/1s; ii) 600 MPa/300s and two others treatments of 2 cycles of HHP, iii) 2 cycles of 600MPa/1s and iv) 1 first cycle of 400 MPa/1s and second cycle 600 MPa/1s. The microbiological population and polyphenoloxidase activity (PPO) of treated RGP was studied immediately after the treatments and at 270 days after the treatments at temperatures of 4 and 20 ºC respect a control sample untreated. The treatments significantly reduced the microbial population; the effect of HHP3 and HHP4 (two cycles) did not differ from those of HHP1 and HHP2 (1 cycle). Phenolic compounds (anthocyanins, flavanols, flavonols, phenolic acids and stilbenes) were extracted from GRP, identified and quantified by HPLC. The values of all these phenolic families were maintained immediately after HHP with exception of a decrease of anthocyanins in HHP3. However, the HHP treatments did not affect the polyphenoloxidase enzyme, since the phenolic compounds were notably reduced during storage although phenolic compounds were better well-preserved at refrigeration than at room temperature.

This article discusses the current state of the cement market in Kazakhstan at the present stage. Construction in Kazakhstan is one of the parameters for the development of the country's economy. The rapid development of construction companies made it possible to concentrate the location of cement production in those regions where the main cement production enterprises are concentrated. Assessing the global development of the cement industry, it can be noted that the main consumer is the People's Republic of China, but by 2050 significant development is expected in India and African countries. Considering the existing production volumes of cement in Kazakhstan, the total volume reached 12 million tons. Based on the development trends of GDP, construction works, cement production, a linear model was developed, with the help of which a forecast was made for the development of cement production for the period 2023-2025 in Kazakhstan. Given that the cement industry is a dirty industry, suggestions are made for the latest technologies and existing innovations. Proposals include reducing emissions by using new types of cement that require less heat to produce, and using carbon capture and storage technology. Also, with the continuous growth of population and urbanization, there will be the use of cement-based substances in various fields such as civil engineering, medicine, etc. using new types of cement that require less heat to produce, and using carbon capture and storage technology.

Published: December 2023

This article proposes a prefabricated modular design in which springs and hinges have been used to assist the column’s passive installation (energy efficient In this technique, the roof panel and column were joined by a pivot hinge in the factory, enabling the pieces to be hoisted by the crane as a single unit for installation on the worksite. Also, there is a spring installed at a specified distance in the roof panel to assist in pushing the column and fastening it. This method helps to speed up the process of installing elements on the worksite, by reducing the number of times that the crane is used to lift elements throughout the installation process because instead of lifting one element each time, it lifts the two elements together at the same time. It is an efficient approach to reduce effort, time, and cost. In addition, the effect of the spring’s position in the panel on the amount of force required to push the column vertically was estimated in this study. The results demonstrate that the farther the spring distance from the pivot hinge, the less thrust force is required to elevate the column. Concerning the hinge that connects the roof panel to the column. The shear and crashing stresses that may be subjected to the hinge throughout the process of vertically installing the column were estimated to be within allowable limits.

The pandemic situation like COVID-19 worsened the medical situation in India, and the crisis of medical oxygen availability at hospitals in different parts of India has also been a deep concern. In this study, we analyzed the supply chain of medical oxygen from manufacturing units to the needy capital cities of states. A two-mode optimization model has been developed for better planning of transportation and supply of medical oxygen. Various industrial units with a liquid oxygen production facility have been considered as sources while road and rail routes have been considered as modes of transportation. Finally, the oxygen cylinders/tankers are transported by road to hospitals. The mathematical model tries to optimize the route and transport medium, considering various constraints. This paper identifies the challenges in Indian contexts and tries to address them by an optimal, cost-effective, and efficient planning for medical oxygen transportation.

Published: December 2023

In the present era, numerous researchers are actively exploring diverse approaches to modify Bituminous Concrete (BC) and seeking alternative paving materials to extend the lifespan of road surfaces and to enhance the longevity and resilience of bitumen pavements, while simultaneously mitigating environmental pollution stemming from hydrocarbon materials. Among the effective materials employed for AC modification, fibers have emerged as one of the successful choice. This research focuses on investigating the inherent self-healing capabilities of bitumen when incorporating glass fibers and assess their impact on the bitumen mixture. Glass fibers are known for their elevated tensile modulus and exceptional heat resistance. The mixture containing glass fibers is evaluated for its characterisation, determining the optimal glass fiber content along with the corresponding binder content. The study encompasses an examination on optimized samples for Self-Healing by Indirect Tensile Strength, and repeated load Indirect Tensile Strength. The outcomes yielded positive results, demonstrating that the inclusion of glass fibers led to an augmentation in strength and healing, both under static and dynamic loading conditions.
Study on the Effect of Void Geometry and Location on Electric Field Distribution and Partial Discharges in HVDC Cables
Authors: Subramaniam Sundaramahalingam , Thiruvelmurugan Janani , Anbuselvan Shanmathi
Published: December 2023

Nowadays HVDC transmission systems are preferred over HVAC systems because of their less power loss and high reliability. In the HVDC cable transmission system, there is a problem of Partial Discharges (PD) occurring due to cavities of the dielectrics in HVDC cables. The distribution of the electric field may change in the presence of partial discharge, which has an impact on how the electric system normally functions. Under DC conditions, partial discharge characteristics are influenced by the electric field distribution and electrical conductivity. Discharges tend to occur quickly when the cavity field reaches the inception level. Hence it is necessary to monitor the conditions of the HVDC cable for better transmission. A 2-D FEM-based model is developed for the simulation of PD due to various shapes of voids at various locations in the cable insulation using ANSYS. Also, PD modeling is the most important concern in identifying the influencing parameters and physical mechanisms of the PD phenomenon. In this work, the Three capacitances model is used to estimate the model parameters and simulate the partial discharges in MATLAB. The results from the simulation are compared with analytical models. It is observed that pulses of the partial discharges vary with the dimensions of the void, type of void materials, and location of the void.

Cold pelletized asphalt concrete mixture from reclaimed asphalt
Authors: Ignatyev Aleksey Aleksandrovich , Gotovtsev Valerij Mikhailovich , Slepnev Pavel Alekseevich
Published: December 2023

The authors of the article propose a technology for the sustainable reuse of old asphalt concrete granulate, the stockpiles of which increases annually by tens of thousands of tons. The article describes an approach that allowing to process the granulate of old asphalt concrete to make cold asphalt mix, equal in terms of strength and water resistance to hot asphalt mixes. Pelletizing old asphalt granulate concrete in a heated state leads to stratification of large agglomerates with the further building of granules from small particles of the material. These processes lead to a change in the initial dispersed composition of the old asphalt granulate, along with the structuration of the material. The resulting material is not subject to caking and can be stored for a few years in a cold state and does not require preheating when laying in the pavement. Its preliminary classification and fractionation are not required for the production of pelletized material based on the old asphalt granulate. After milling it can be immediately used for the preparation of a pelletized asphalt mix, which is crucial in terms of material reuse.

Published: December 2023

This work is devoted to the study of the influence of various types of dispersed reinforcement of basalt fiber on increasing the frost resistance of high-strength modified basalt concrete. The article presents the results of experimental studies of one composition of coarse aggregate concrete modified with the admixture "Embelit 8-100" and three compositions of basalt fiber concrete. 3 types were considered as dispersed reinforcement: mono-reinforcement with basalt fiber of 24 mm length – soft fiber, mono-reinforcement with basalt micro-reinforcement of 25-40 mm length – stiff fiber, poly-reinforcement with a mixture of soft and stiff fiber in a ratio of 1:1. According to the test results, experimental values of physical and mechanical characteristics of coarse aggregate high-strength concrete and basalt fiber concrete with three types of dispersed reinforcement (at the age of 7, 14, 28 days) were determined: cube strength, concrete compressive strength class, elastic modulus, frost resistance grade concrete. The analysis of the effect of different types of dispersed reinforcement on increasing the strength and frost resistance of coarse aggregate basalt concrete modified with the admixture "Embelit 8-100" was also carried out. The conclusion is made about the prospects of using mono-reinforcement in the form of soft basalt fiber to increase the frost resistance of high-strength basalt concrete.

Authors: Kozlova Irina , Zemskova Olga , Skopova Alina , Borisenkov Nikita
Published: December 2023

The development of nanotechnology contributes to the production of a new generation of multifunctional building materials. Carbon nanotubes (CNTs) are one of the components that make it possible to obtain such materials. CNTs are so small that they are prone to aggregation. To exclude this phenomenon, it is necessary to subject the particles to ultrasonic dispersion and stabilization. The purpose of the study was determined, which is to stabilize CNT suspensions and study of the properties of cements and concrete mixtures containing stabilized CNT particles in their composition. During the research, we have established the optimal dispersion parameters (t = 25±2 °C, υ = 44 kHz, τ<30 min) and the stabilizer concentration (5 g/l). The tests on the compressive strength of modified cement samples showed that the complex additive, which includes polycarboxylates and CNTs, gives the maximum increase in strength in the first day by 60%, in 28 days - by 20%. The introduction of CNTs into the composition of the concrete mix increased the compressive strength by 32% on the 3rd day of hardening, and by 34-39% on the 28th day compared to the control composition without additives.

In the design and construction of residential and industrial buildings outbuildings, it is necessary to use effective thermal insulation materials that provide a comfortable microclimate in the room, as well as the required conditions for implementing technological processes. An essential factor is the reduction of the negative impact on the environment, which is expressed both in the reduction of energy consumption and in the possibility of rational use of industrial waste for partial replacement of the main raw material components. To increase the efficiency of heat-insulating materials based on foamed polyethylene, it was necessary to develop a technique for selecting the composition of synthetic polyethylene foam matrix, considering the possibility of using secondary modified polyethylene foam at different foaming modes. The compositions of modified polyethylene foam were selected using statistics methods and analytical optimization. The developed bases of optimization and composition selection methodology allowed to establish optimal consumption values of main components and process parameters corresponding to the specified requirements. Using alignment charts, the solution of the predictive problem of estimation of values of strength and average density of foamed polyethylene depending on the value of consumption of main components was realized.

Reverse Osmosis method is efficiently and widely used in drinking water production. Treatment of ground water faces three` main problems: scaling of membranes, concentrate handling and permeate ionic composition. A number of ionic pollutants (such as lithium, ammonia and boron) are poorly rejected by reverse osmosis membranes as compared to calcium and chloride ions. Thus, in cases when high lithium or ammonia concentrations are present in ground water, high rejection reverse osmosis membranes are usually used that provides a product water with low TDS and hardness values. Present article demonstrates results of research aimed at development of a new approach to change a ratio of monovalent and divalent ions in product water. An example of high boron water is discussed. A developed technique of ion separation is applied and experimental results are demonstrated, thus providing low boron concentration in product with increased TDS and calcium by 5 times as compared to the initial use of RO membranes. A flow diagram of the developed process is demonstrated based on experimentally obtained results.

This work is a further development of the authors' COVID-19 pandemic consequences research. The dynamics of the cough aerosol cloud was studied. An experimental setup for fixing spatial and temporal distributions of aerosol cloud velocities was used. Flags were placed on the threads of the experimental setup. On the first and second frames, the area and shape of the flags were different. The process of air passing through the frames was recorded by photographic equipment. The footage was compared by a computer program to identify differences.The results of an experiment with five adults (18–22 years, men), volunteered for study participation, are presented. The method of aerosol cloud visualization is applied. The dynamic parameters of the aerosol cloud are estimated. The velocity of the air flow arising from coughing was measured. The shape of the flow was determined depending on the time. It was found that the flow front moves with acceleration at the initial stage of propagation and with a constant velocity at the final stage. A nonlinear dependence of the change in the volume of cough air flow aerosol on time was established.

Published: December 2023

The article outlines consolidated research areas that bring risk assessment results into the integrated safety of industrial enterprises. The author compares currently used methods for assessing industrial safety, fire safety, and occupational safety subsystems, included in the system of integrated safety of industrial enterprises, and a new method for assessing integrated safety. Three tasks must be solved to make industrial enterprises safer. To solve the first task, scientific research results, currently applied in Russia and worldwide, were analyzed. The conclusion is that the damage from hazardous events can be reduced using a reasonable safety margin, required to reduce (eliminate) various risks, the rational application of the safety margin using the approach stemming from a new vision of risks. When the second task was solved, current methods of assessing subsystems of industrial safety, fire safety, and occupational safety, included in the system of integrated industrial safety, were compared with a new technique used to assess integrated safety. The objective of the third task was to present a formalized description of a new model for improving and developing an integrated safety system for explosive and flammable production facilities. The purpose of risk assessment is formulated; new integrated safety assessment methods and results are presented. As a result, the three above-mentioned tasks are solved, and the conceptual model of an integrated safety system is developed for Russian industrial enterprises.

Reducing the dangerous potential of global warming and its impact on climate change requires reducing carbon dioxide emissions into the atmosphere, which is inextricably linked to reducing the burning of fossil fuels. There are various techniques to accomplish this task. One of such technologies is the maximum use of excess heat of exhaust gases with the subsequent condensation of vapors contained in them and use of the obtained heat for own needs of the heat energy source. Because there are many designs, it is necessary to carry out various studies to determine the optimal design of these apparatuses. In order to fulfil this work, we have made a laboratory model of a condensing economizer with a developed heat exchange surface. We also carried out a series of tests to construct graphical dependences of experimental data, which will help us to determine the heat transfer coefficient from flue gases to water taking into account the condensation of water vapors and to calculate the optimal geometry of channels for the flow of different heat carriers. All these studies will allow us to obtain the optimal design of condensing economizer.

From the very first day (beginning) of operation, the processes of gradual reduction of the established parameters of functional quality of the living environment and the material shell of the architectural object are formed. The study aims to analyze the current factors influencing the appropriateness of the decision to reconstruct the residential environment and the peculiarities of the interaction of the “increased” quality of the residential object after its reconstruction with the surrounding space. Research methods include analysis, systematic approach, generalization of scientific works, practical developments to improve the functional quality of the living environment, and their synthesis using relevant and verified information materials. As a result of the conducted research, the main types (groups) of influence factors that determine the feasibility, as well as the quantitative and qualitative composition of measures within the framework of reconstruction, the conditions of efficiency of the corresponding construction production, as well as the criteria of the interaction of the “new quality” of the residential environment with the surrounding space of the object have been established. The study’s main conclusion is the assertion of the dependence of the quality of development and implementation of solutions on the systematic analysis of the causes and consequences of the reconstruction of the residential environment.
Geo-ecological aspects of the de-icing chemicals’ impact on the geological environment of urbanized areas

The problem of the influence of de-icing chemicals on the geological environment of urban landscapes is raised. In connection with the increase in passenger traffic and the load on the road network, the problem of using a deicing chemical (DIC) is acute. DICs adversely affect the environment, getting into the soil and groundwater, increasing their aggressiveness. In particular, chemicals affect the rocks of the base structures, which are represented by minerals of the carbonate class. The impact leads to leaching and dissolution of carbonates and the formation of karst cavities, which, when enlarged, can lead to subsidence of the surface, often to failures and, as a result, to deformations of structures. They cope well with the task of ensuring road safety by melting ice at low temperatures, but this decision also has a number of negative consequences for urban areas. It is important that these salt mixtures, in addition to their primary task of chemical melting of ice, continue to enter into chemical reactions with environmental components: soils, base rocks, groundwater, which causes significant harm to the urban environment. The general ecological situation of the city is deteriorating, and there is a risk of developing dangerous geological processes.

For problems involving the interaction of structures with sediments, physical models cannot be used for quantification because of the non-modellable nature of sediment dynamics. Mathematical modeling of sediment dynamics is used. The basis for verifying modeling results for such problems is in situ studies of coastal dynamics over a multi-year period, which are often not available. It is therefore possible to use the analysis of space images for a multi-year period together with a mathematical description of the dynamics of the coast under study. The subject of this paper is the coast of the Gelendjik Bay, Black Sea. An assessment of the coastline dynamics in the conditions of 5 extreme wave storms of 30-year period is made using mathematical modeling. To verify the results, the analysis of space images of the coastal zone for the period 2003-2022 is applied. The effectiveness of the proposed approach for predicting the intensity of sediment accumulation and erosion is shown and the mathematical model used is verified.
