Published: May 2024

The article defines the main issues and prospects for the development of the ecocity concept in terms of sustainable development. In the process of identifying the main problem, the relevance of the research was determined. Having conducted a thorough analysis of the existing state of ecocities formation in conditions of sustainable development, it was found that the development of ecocities is multi-vector and includes energy-efficient, ecological and economic aspects, while the impact on the environment is minimal. The main trends in the development of ecocities were identified, which made it possible to determine their role in the formation of a modern urban environment in terms of increasing the energy efficiency of buildings, using solar energy, "green" technologies and the latest materials. On the basis of the conducted research, the main directions of urban development of the ecocity were determined: ecological construction and energy saving, use of alternative energy sources, ecotransport, waste disposal, creation of ecological infrastructure.
The main recommendations that must be followed to improve the ecocity: use of ecological materials (reduction of the ecological footprint of the product), use of ecological production processes, the maximum efficiency of using the resource potential of products by considering the life cycle of the product from creation to disposal, high product quality for extended service life, minimization of repairs and mandatory reprocessing.
Therefore, it can be concluded that the creation of ecologically favorable conditions in settlements is a rather complex process.
ANALYSIS OF ATMOSPHERIC AIR POLLUTION IN KYIV FOR 2014-2024
Authors: Solukha Igor
Published: May 2024

Considered changes in the state of atmospheric air pollution in the city of Kyiv for 2014-2024 within the city limits.
It was established that, in accordance with the analysis of atmospheric air indicators, during the analyzed period, the level of atmospheric air pollution in the territory of the city of Kyiv was mainly in the range of "very low" and "low".
The main dependence of the quality of atmospheric air in the city of Kyiv on the emissions of mobile sources of influence, namely road transport, as the main source of atmospheric air pollution, has been established. 
Air pollution is one of the most important environmental problems in Kyiv. Urban transport is the main factor of atmospheric air pollution, the influence of the "car-road" system on the natural environment in the conditions of the city is much greater than that of industry and heat energy, which is connected with a large number of motor vehicles, the presence of large areas of roads and streets.
Motor vehicle emissions are represented by exhaust gases (after fuel combustion), crankcase gases (a mixture of fuel with vapors of lubricants) and fuel evaporation entering the environment from fuel tanks, carburetors and engine power systems. The most significant emission components are carbon monoxide, hydrocarbons, nitrogen oxides, sulfur compounds, solid particles (soot).
Atmospheric air pollution problems should also include the increase in the number of autonomous boiler houses in the city, because in connection with the growing pace of the city's development, there is a discrepancy in the real ability of energy companies to provide heat to consumers. Currently, the centralized urban heat networks are already overloaded, and the addition of additional consumers requires the installation of additional heat-generating equipment of the appropriate capacity. There is a need to use modern progressive boiler units with as low as possible pollutant emission rates, to implement energy-saving technologies, to solve the problem of achieving minimum losses on the way to transport heat to consumers, etc.
The further study of the analysis of the state of the atmospheric air in large cities of Ukraine based on the experience of other countries for the better development of the concept of ecological development and the implementation of an ecological assessment of the state of the environment is substantiated.
SOME ASPECTS OF ENERGY-EFFICIENT TECHNOLOGIES APPLICATION IN HISTORICAL BUILDINGS’ RENOVATION
Authors: Holyk Jolana , Vantyukh Diana , Stetsko Ivan
Published: May 2024

Energy saving is one of the important directions of modern strategy in the field of construction because in Ukraine, twice as much natural fuel is consumed per 1 million m3 of living space during the heating period as in Europe. Energy-efficient reconstruction of buildings consists of ensuring energy-saving functioning through the use of modern active engineering and technical solutions and technical installations, as well as possible passive measures (wall insulation, optimal type of double-glazed windows, etc.). The issue of energy efficiency during the renovation of historical buildings requires special attention because the building is a collection of architectural and urban heritage objects that are subject to maximum preservation. The purpose of the article is to reveal the peculiarities of the renovation of historical buildings using modern energy-saving technologies based on the analysis of world experience. A common problem with many historic buildings is their careless maintenance, which leads to a number of technical deficiencies, such as high energy consumption and low thermal comfort. Therefore, the need for renovation of historical buildings is met by combining restoration work with measures to ensure energy efficiency. The article highlights the issue of increasing the energy efficiency of buildings related to historical architecture using the examples of the Sofiero Castle located in Helsingborg (Sweden), the Palace of the Hungarian Academy of Sciences, the Aspinall Courthouse (USA), and the Osram building (Denmark). First and foremost, theoretical developments on this topic are considered. The main modern methods of increasing the energy efficiency of buildings are outlined. Examples of world experience in the use of energy-efficient technologies and energy modernization during the reconstruction of buildings related to historical architecture are given. The design and implementation of works on the restoration of historical monuments, as well as the application of appropriate energy efficiency measures, require an individual approach to each historical building after careful analysis of the world's modern one’s theoretical developments and practical experience.
MODERN METHODS OF DETERMINING PLUMBLINE AND GEOID SURFACE DEFERENCES
Authors: Honcharenko Oleksandr , Denysiuk Bohdan , Katushkov Volodymyr , Kuzmych Oleksandr
Published: May 2024

Today, global navigation satellite systems (GNSS) are widely used for the development of national geodetic networks and geodetic research. However, there are some applications where GNSS observations should be integrated with traditional ground-based geodetic measurements (e.g., underground engineering surveys, monitoring of hydraulic structures, etc.) In order to integrate GNSS observations and traditional measurements using a high-precision anti-aircraft camera, it is necessary to know the deviation of the plumb line, defined as the angle between the gravity vector and the ellipsoidal normal at a given point.
If the astronomical and ellipsoidal coordinates are determined simultaneously, you can immediately obtain the values of the plumb line deviations. Using the values of the deviations of the plumb lines, you can determine the undulations (ondulations) of the geoid using astronomical and geodetic leveling. You can also determine the orthometric height if you know the height of the ellipsoid (GPS) and the waviness of the geoid.
A CCD sensor with a telescope pointed at the zenith, in combination with DGPS, allows you to determine the ellipsoidal coordinates, as well as the astronomical coordinates in about half an hour with high accuracy.
Determining the deviations of plumb lines using a portable DSC set and a GPS receiver is a fairly convenient and compact measurement tool. The experimental studies of the high-precision anti-aircraft camera confirmed the theoretical calculations; in particular, the accuracy of determining astronomical coordinates does not exceed ±0.35". The maximum fluctuation of the values of the components of the plumb lines deviation in the meridian plane was 0.45˝, and in the plane of the first vertical - 0.80˝.
A Graphical User Interface Based on Logistic Regression Approach for Malarial Detection
Authors: Kumar Manish , Sarkar Bikash
Published: May 2024

Malaria (a mosquito-infected disease) is one of the deadliest communicable diseases in the world. The disease causes a significant global health challenge. According to the World Health Organisation (WHO), millions of deaths occur every year worldwide. The mortality rate poses a challenge to authority and management. Over the years, mathematical and machine learning (ML)-based techniques have been developed to mitigate the scenario. In this study, ML-based prediction techniques are investigated to predict the presence of malaria in individuals. More specifically, three ML-based techniques—Logistic Regression (LR), Support Vector Machine (SVM), and Random Forest (RF)—are employed to differentiate their prediction performance (namely, classification accuracy, precision, recall, and F-score) over a created database (D) consisting of 350 records. Among the adopted techniques, the LR technique shows overall better performance over the test data chosen from D. A graphical user interface (GUI) based on LR is also developed to detect the presence or absence of malaria in any individual.

The word "clinamen", which means "deviation", was introduced by the Greek philosopher Epicurus to oppose the atomic determinism of Democritus. What is the relationship between clinamen and notions such as freedom or slavery? In other words, what who were the founding fathers of Western civilization? In fact, the issue of freedom and slavery can be traced back to the proto-Indo-European civilization (PIE), which appears to have emerged around 3500 BC. Here we propose that in order to integrate clinamen, it is absolutely necessary to be open and tolerant of new ideas. This also means that one must be careful not to confuse science with technology or spirituality with religion.
Reporting and Subjectivity Traps: A Brief Opinion Article on Consciousness as Belief
Authors: Martin Antonio , O'dea Martin
Published: May 2024

We explore the notion that consciousness may be more of a belief than an empirically verifiable fact, shaped by the subjective nature of our experiences and the inherent limitations of reporting them. Contemporary science has yet to provide definitive proof of subjective experience beyond self-reports, which even sophisticated machines could mimic under specific conditions. Philosophical concepts such as phenomenological zombies—creatures identical to us but lacking consciousness—highlight the difficulty of distinguishing between actual conscious experience and mere behavioral reports. Current experimental designs often conflate metacognition (beliefs about perception) with consciousness, as seen in Higher-Order Thought theories and the Perceptual Reality Monitoring theory. These frameworks suggest that our sense of being conscious arises from metacognitive processes, potentially leading to cognitive biases. Studies involving disruptions to brain regions responsible for metacognitive accuracy further complicate our understanding of consciousness. Additionally, phenomena like delusional misidentification syndromes challenge the assumption of a coherent self that reliably perceives and reports reality. By questioning these assumptions, we propose that consciousness might be an elaborate belief system, a convenient construct for survival rather than an intrinsic quality of our being. This perspective urges a reconsideration of the fundamental nature of consciousness and our approach to studying it.

Successful breeding of spring wheat varieties that are productive, have high grain quality, and are well adapted to Siberian conditions depends on the availability and knowledge of the source material. In this regard, the purpose of the research: to study the influence of the timing of sowing early ripe varieties of winter wheat and winter wheat varieties of alternate wheat on the yield and quality of grain in the northern forest-steppe of the Tyumen region. Methods. There were used in the study of generally accepted methods in the State Variety Test. Scientific novelty. In the conditions of the forest-steppe zone of the Tyumen region, new varieties of early ripening winter wheat Rannyaya 12, Skorospelka 3b, Starshina and alternate wheat varieties Pallada, Lastochka. Results. In 2022–2023 we studied on the experimental field of the State Agrarian University of the Northern Trans-Urals the influence of pre-winter and early spring sowing dates on the yield and quality of grain. It was established that during winter sowing (October 15) and early spring (April 22), the studied wheat varieties grew and developed normally. At the same time, they formed a well-developed leaf surface, of medium height, and straw resistant to lodging. In both years of research, the studied varieties ripened in the third ten days of August. The yield with winter sowing was 59.5–71.0 c/ha, for the spring standard variety Ikar – 41.9, with early spring sowing – 51.2–65.4 c/ha, for the standard variety 35.3. Productivity was combined with grain quality: protein content – 14.5–16.4 %, gluten – 29.0–34.2 %. The wheat varieties under study must be used in hybridization with spring varieties, as well as seed propagation must continue to establish a production test.

The aim of the study is to assess the influence of candidate genes encoding aquaporins (AQPs): AQP3, AQP7 and AQP11, associated with indicators of bull semen quality, for their further use as transcriptional biomarkers. Methods. Using quantitative reverse transcription polymerase chain reaction (RT-qPCR), we assessed the expression of selected genes in native and frozen-thawed sperm of 7 Holstein bulls and analyzed the correlations between the expression level of the studied genes with indicators of sperm quality that are significant for survival and fertilization. The following biochemical parameters of native and deconserved bull spermatozoa were assessed: motility, cell morphology, membrane integrity, viability, mitochondrial membrane potential, level of generation of reactive oxygen species (ROS). The scientific novelty of the study lies in the fact that for the first time in our country the relationship between the expression level of the AQP3, AQP7 and AQP11 genes and the quality of sperm of Holstein bulls was assessed. Results. The AQP11 gene can be recommended as a reliable transcriptional biomarker, since it had a high positive correlation with the content of living (0.821, p = 0.0145), normal (0.750, p = 0.0384) cells, and a negative correlation with the content of defective (–0.679, p = 0.0735), dead cells (–0.821, p = 0.0145) and ROS content (-0.821 p=0.0145) in frozen-thawed and native sperm. The AQP7 gene transcript of frozen-thawed sperm had an average negative correlation with indicators of dead sperm content (–0.727, p = 0.0545) and acrosome defects (–0.667, p = 0.0735) at a level close to significant. The AQP3 gene transcript had a significant positive correlation with the content of dead cells (0.786, p = 0.0251) in frozen-thawed sperm and a negative correlation with the content of defective, dead cells and ROS content in frozen-thawed and native sperm.

Abstract. Improving agricultural technology and supporting plant reproduction in the collections of botanical gardens remain relevant. The purpose of the research is to study the effectiveness of using the preparation “Lignohumate AM” in floriculture and reproduction using the example of representatives of the generic complex Iris L. The objects of study are species and varieties of the genus Iris (I. sibirica L., I. pseudacorus L., I. hybrida hort. ‘Edith Wolford’, ‘Banbury Ruffles’, ‘Before The Storm’). Methods. Treatment of plants was carried out at different phases of plant development, spraying leaves, watering experimental samples, and also combining both options − foliar feeding with root feeding. Plants treated with water served as control. Scientific novelty. For the first time, we studied the effect of humic substances on representatives of the genus Iris L. Results. A significant increase in the length (‘Before The Storm’ – by 7,8 %) and width of vegetative shoots (‘Banbury Ruffles’, ‘Before The Storm’ – by 5,6 and 3,7 %, respectively) was revealed. Treatment of plants with “Lignohumate AM” had a positive effect on the water regime of irises. Water deficit decreased by 2,8–5,3 % as a result of root treatment, water-holding capacity increased by 5,7 % during irrigation and mixed treatment. The preparation “Lignohumate AM” had no effect on the germination of seeds of I. sibirica and I. pseudacorus, but was highly effective in a long-term experiment. “Lignohumate AM” contributed to a reduction in the loss of one-year-old I. sibirica plants by 20,8 %, as well as the growth of surviving I. pseudacorus plants by 39,7 %. The stimulator also showed a significant prolonged growth-stimulating effect, which contributed to improving the quality of seedlings. The length of leaves under the influence of the preparation increased by 64% for I. sibirica and 17 % for I. pseudacorus, the width of leaves of I. sibirica increased by 14 %. Based on the results of the study, the growth stimulator “Lignohumate AM” can be considered an effective promising drug for use in floriculture and the reproduction of ornamental and rare species of iris.
