Authors: Hryhoruk P M , Khrushch N A , Grygoruk S S , Ovchynnikova O R 
Published: November 2023

Abstract
Assessing the economic development of countries in the context of the tasks defined in the UN 2030 Agenda for Sustainable Development is essential from the point of view of determining progress in achieving the SDGs. It becomes especially relevant in periods of global challenges and disturbances, one of which is the COVID-19 pandemic. The goals of SDG8 and SDG9 contain indicators that are determined mainly by the state of development of the country’s economy, so the analysis of trends in their changes is important in the context of identifying trends in economic growth in general, as well as for evaluating progress in achieving these goals. The purpose of the study is to identify the impact of the COVID-19 pandemic on the economic development of countries to achieve sustainable development goals and assess progress trends in the post-pandemic recovery of the economies of Eastern Europe by analyzing quantitative data from official statistical sources. The object of the study is the economic development of Eastern European countries in the conditions of the COVID-19 pandemic. The study period covers the time range from 2017 to 2021 and includes both the pre-pandemic and pandemic periods. Eight countries of Eastern Europe were chosen as research objects. Indicators of official statistics related to SDG8 and SDG9 sub-goals were selected for analysis. The study showed a significant decrease in the values of most indicators, which was caused by the destructive effect of the pandemic. To assess the possible development trajectory, we calculated the estimated value of indicators for 2022 using the Holt-Winters method. The results showed that, despite some progress in 2021, in 2022, the values of the indicators are decreasing. Such estimates correspond to the trends provided by international institutions. We have built a composite indicator to assess the economic development trend comprehensively. The results of the evaluation confirmed the general trend towards a decrease in the level of economic growth in the context of the goals of SDG8 and SDG9 for all the countries of Eastern Europe selected in the study.
Mining tourism as a guarantee of sustainable development of industrial regions (on the example of Kryvyi Rih region)

Published: November 2023

Abstract
Sustainable tourism is fundamentally about preserving and enhancing natural, historical, or cultural heritage, as well as promoting activities related to local identity and history. For mining regions, one of the ways to diversify their economies on a sustainable basis is to develop the tourism sector. The development of niche forms of tourism, which are fully focused on the resources of the industrial area, helps to supplement and diversify the tourist offer in these regions, including industrial tourism and one of its areas - mining tourism. The objective of the study is to reveal the importance of sustainable development for an old industrial region, using Kryvyi Rih as an example, by intensifying tourism activities that would maximize the social, economic, cultural, and environmental benefits of tourism. The research is based on the dialectical method of cognition and a systematic approach. The research was carried out on the basis of parallel use of theoretical (comparative analysis, abstraction, specification and generalization) and empirical methods (expeditionary methods, observations, the method of field visual inspections, content analysis, etc.) As a result of the study, approaches to the concept of “mining tourism” were structured, and the key objects of interest of consumers of this tourist destination were identified. Global trends in the transformation of industrial areas for the needs of mining tourism were analyzed. The information on mining facilities in Kryvyi Rih is systematized and their suitability for the tourism sector is diagnosed. Based on the diagnostics, the use of various mining facilities in thematic tour programs is proposed, which is confirmed by the results of practical tourism activities.
Assessment of military destruction in Ukraine and its consequences using remote sensing

Published: November 2023

Abstract
The article raises the problem of using Earth remote sensing data to collect evidence of damages caused by the military actions of the Russian army in Ukraine. The core data set obtained by deciphering aerial photographs reflects the general current and operational situation in the affected area, reducing the subjectivity and uncertainty of damage characteristics on the ground. Earth remote sensing data visualize visible damage to the environment, which can be recognized and assessed using images of different spectral bands with appropriate resolution. Among the damage caused to the environment as a result of hostilities, according to the Earth remote sensing data, it is possible to study: degradation of land resources, destruction of natural ecosystems by fires, destruction of structures (buildings) and structures. Satellite images with a very high resolution (≤ 1 m) make it possible to quantify the degree of damage to the soil surface due to shell explosions: the amount of metal fragments and chemicals that have entered the soil, damage to the biological cover, etc. Images with a resolution of less than 30 meters in the short-wave infrared (SWIR) range allow to depict the devastating effects of forest and steppe fires caused by military actions. Using two different time frames, one before the fire and one after, will ensure the accuracy, objectivity and reliability of the evidence collected. These very high resolution Earth remote sensing images are used to investigate the destruction of structures (buildings) and constructions. The analysis of satellite images guarantees the diagnosis of the condition of the building in three degrees of destruction: completely destroyed, partially destroyed or not destroyed. In order to ensure the storage, quick search, analysis and visualization of all useful information obtained from the data of Earth remote sensing, it is necessary to use geoinformation systems.The proposed methodology for assessing military destruction is characterized by simplicity, accuracy and versatility, and does not require the use of expensive equipment.

The problem of rational use of mineral resources and mining waste in the context of sustainable development of regions
Authors: Syvyj M J , Ivanov Y A , Panteleeva N B , Varakuta O M 
Published: November 2023

Abstract
Efficient use and protection of the subsoil is a part of rational nature management in the mineral base of Ukrainian regions and Ukraine as a whole. The components for the rational use of the subsoil include a comprehensive development of mineral deposits, a comprehensive use of mineral raw materials and mining waste, optimization of the structure of mining production and mineral raw materials consumption. The rational use of mineral resources in the modern interpretation of this issue extends to all stages of their development, including the issue of waste disposal. A huge amount of mining waste has been accumulated in administrative regions of Ukraine, and the issue of their disposal has gone beyond just an economic and ecological problem and has acquired a significant socio-demographic significance. Environmental problems have become particularly acute due to the accumulation of toxic waste, among which the most dangerous are heavy metals, petroleum products and acid tars. For the sustainable development of Ukraine, it is necessary not only to develop new reserves of natural raw materials, but also technogenic minerals accumulated in more than 1,600 man-made deposits and objects. The further development of the mineral base requires, at the state level, an urgent solution to problems that hinder the development and ecological rehabilitation on the ground of rational use.

Authors: Dotsenko N A , Gorbenko O A , Batsurovska I V 
Published: November 2023

Abstract
The article presents the investigation of constructive and technological parameters of an energy-efficient screw oil press. It is outlined the principle of operation of an energy-efficient screw oil press. The construction of the oil press is improved by the steam atomizer that is installed in the receiving hopper under the rifled rollers for moisture-thermal treatment with steam, which is completed with the heat exchanger, heating element, expansion tank and hydro group. Also, a steam generator connected to a steam atomizer which is embodied into the receiving hopper. It was analyzed the influence of the optimization criteria (oil yield, energy consumption and press productivity) on the efficiency of the technological process. These optimization criteria depend on the main independent factors: the length of the reception and preparation chamber, the material (sunflower pulp) moisture; the heating temperature, the screw rotation speed, the linear speed of movement of screw shaft turns. The optimal constructive and technological parameters of energy-efficient screw oil press are considered. The energy-efficient screw oil press refers to the equipment of the oil enterprises of small productivity and due to its design, it allows to use a simple technological scheme of oil pressing and to reduce the amount of energy and resources spent on the technological process in the context of use in sustainable food systems.

Published: November 2023

Abstract
Using GIS technologies, the article analyzes, systematizes, and processes, the data obtained in the process of geodetic monitoring of man-made territories and objects, which will make it possible to analyze the existing state of the object and provide an opportunity to determine critical spatial deviations that can lead to irreversible processes of destruction of buildings and structures. This provides an opportunity to prevent processes that can lead to large-scale disasters, as well as determines the adoption of timely measures to prevent the destruction of structures and predict emergencies.
Determination of the thermal stress state for the composite brake pad of a wagon at operational loads
Authors: Panchenko S V , Vatulia G L , Lovska A O , Ravlyuk V G 
Published: November 2023

Abstract
The article provides the results of determining the thermal stress state of the composite brake pad of a wagon. The research is made by means of computer simulation with the finite element method using the SolidWorks Simulation options. The design diagram of the pad includes not only the horizontal loads due to its pressing to the rolling surface of the wheel and the friction force, but also the temperature impact taken equal to 400°C. Since the composite material of the pad is fragile, the Mohr–Coulomb criterion is used as a calculation criterion. It has been found that the maximum stresses occur in the upper part of the pad in the contact area between the back plate and the side plate and do not exceed the permissible values. The article presents the results of the calculation of the thermal stress state of the pad with dual wedge-shaped wear. The study includes the actual parameters of the pad wear determined during operational research. The results of the calculation show that the maximum stresses occur in the back plate of the pad and exceed the permissible values by 19.8%. This is explained by the fact that the useful area of the pad decreases, and therefore its loading increases. The research conducted proves the negative impact of dual wedge-shaped wear on the braking efficiency and the strength of the brake pad. This requires development of measures for eliminating this wear.

Published: November 2023

Abstract
Methods for studying brain function and disease heavily rely on in vivo animal models, ex-vivo tissue slices, and 2D cell culture platforms. These methods all have limitations that significantly impact the clinical translatability of results. Consequently, models able to better recapitulate some aspects of in vivo human brain are needed as additional preclinical tools. In this context, 3D hydrogel-based in vitro models of the brain are considered promising tools. To create a 3D brain-on-a-chip model, a hydrogel capable of sustaining neuronal maturation over extended culture periods is required. Among biopolymeric hydrogels, chitosan-β-glycerophosphate (CHITO-β-GP) thermogels have demonstrated their versatility and applicability in the biomedical field over the years. In this study, we investigated the ability of this thermogel to encapsulate neuronal cells and support the functional maturation of a 3D neuronal network in long-term cultures. To the best of our knowledge, we demonstrated for the first time that CHITO-β-GP thermogel possesses optimal characteristics for promoting neuronal growth and the development of an electrophysiologically functional neuronal network derived from both primary rat neurons and neurons differentiated from human induced pluripotent stem cells (h-iPSCs) co-cultured with astrocytes. Specifically, two different formulations were firstly characterized by rheological, mechanical and injectability tests. Primary nervous cells and neurons differentiated from h-iPSCs were embedded into the two thermogel formulations. The 3D cultures were then deeply characterized by immunocytochemistry, confocal microscopy, and electrophysiological recordings, employing both 2D and 3D micro-electrode arrays. The thermogels supported the long-term culture of neuronal networks for up to 100 d. In conclusion, CHITO-β-GP thermogels exhibit excellent mechanical properties, stability over time under culture conditions, and bioactivity toward nervous cells. Therefore, they are excellent candidates as artificial extracellular matrices in brain-on-a-chip models, with applications in neurodegenerative disease modeling, drug screening, and neurotoxicity evaluation.

A Day in Our Life
Authors: Enright Tim 
Published: November 2023

Abstract
At the westernmost tip of Europe lies the island of the Great Blasket. Virtually unknown before this century, it produced a rich and extraordinary flowering of literature that was to make it famous throughout the world. Among its most famous authors was Tomás O'Crohan, the `Islandman', and this book, by his son, is something of an epilogue to his works. Packed with colourful characters and robust Irish humour, it tells of the dying days of the Gaelic-speaking Blasket community, and of its repatriation to West Kerry after the Second World War. Blending nostalgia with sharp observations on mainland life, this is an irresistible memoir of a remarkable way of life.
Psychopharmacological aspects of nicotine
Authors: Warburton David M 
Published: November 2023

Abstract
Any author who writes about the psychopharmacology of nicotine faces a dilemma. If the review is restricted to studies in which nicotine alone has been used, the chapter will be very short. If the review is extended to include the effects of cigarette smoking on behaviour, then the question arises of whether the effects described are due to nicotine alone or whether they are the consequence of some other smoke constituent. Given that there are well over 2000 compounds besides nicotine in cigarette smoke, that possibility can never be ruled out. However, nicotine is pharmacologically the most potent agent in cigarette smoke at smoking-doses, and carbon monoxide has little or no psychological effects at smoking-doses (Guillerm et al. 1978). Consequently, this chapter includes studies of smoking as well as those using nicotine itself, and it discusses evidence of the extent to which nicotine was the essential agent in the behavioural changes.
The emergence of pioneering public health education programmes in the United States
Authors: Viseltear Arthur J 
Published: November 2023

Abstract
This enterprise, when fully understood, must command the liberal sympathy of those who aim to make their generosity fruitful in substantial and enduring public good. William Barton Rogers Schools of public health were established in the United States as a result of a confluence of factors making themselves felt as early as the mid nineteenth century. Such factors included the changing nature of higher education, the development of commerce and industry, the rise to prominence of the science of bacteriology, and the urbanization of the nation-all coupled with a pervasive spirit of utility and a desire to be, in a word, useful. This chapter will explore each line, leading to the establishment of five public health institutions: the Massachusetts Institute of Technology, the joint programme of Harvard and the Massachusetts Institute of Technology, Yale, University of Michigan, and University of Pennsylvania.
Spinal cord stimulation in spasticity and bladder dysfunction
Authors: Illis L S 
Published: November 2023

Abstract
The original use of spinal cord stimulation was for intractable pain and was subsequently used to modify abnormal motor control and bladder dysfunction. Most groups report a relatively modest improvement, but an improvement, in features which were previously intractable and resistant to conventional treatment. Perhaps even more important than clinical effects is the change in ideas about the nature of ‘fixed’ neurological deficit. However, the mechanism of action of spinal cord stimulation is unknown, double-blind studies are impossible to carry out, and not all studies have attempted to use objective measures. As a result the technique is still not widely accepted.
Recreational drugs and sexuality
Authors: Huws Rhodri 
Published: November 2023

Abstract
For centuries people of most cultures have used drugs for recreation. The sought-for effect is either a change in consciousness, altered interactions with other people, or in some cases improved sexual performance. In Old Testament days, Rachael exchanged her marital rights for her sister Leah’s mandrakes, which were presumed to be an aphrodisiac (Genesis 30, 14-17).
Pharmacotherapy for sexual dysfunction: current status
Authors: Riley Alan J 
Published: November 2023

Abstract
Throughout the ages, man of all cultures has sought drugs to modify his sexual performance and an enormous number of preparations of vegetable, animal, and mineral origin have been extolled to have aphrodisiac properties. Even today, vast sums of money are spent on alleged aphrodisiacs, the majority of which are at best ineffective and at worse toxic. In the past there has been very little research effort directed at finding drugs to treat sexual dysfunction and, with few exceptions, most of the drugs that are now used for this purpose were originally developed for other indications. Indeed in the United Kingdom today no drug has been licensed by the Department of Health specifically for the treatment of sexual dysfunction although the butyrophenone, benperidol, is registered for the control of deviant and antisocial behaviour and the anti-androgen, cyproterone acetate, is licensed for severe hypersexuality and sexual deviance in the male.
Modulation of Cardiac Calcium Sensitivity
Authors: Lee John A , Allen David G 
Published: November 2023

Abstract
The devlopment of calcium sensitizers represents the first major innovation in the treatment of heart failure for over 200 years. Unlike other drugs in this area, they do not increase the intracellular calcium concentration and do not have the side effects associated with that mechanism of action. These drugs offer an exciting alternative approach to the treatment of heart failure, and this volume provides an authoritative overview of the physiology, biochemistry, and clinical issues involved. It will be of particular interest to all those concerned with the treatment of heart failure.
