The article reveals the specifics of criminal liability for intentional destruction or damage to someone else's property provided for in Article 194 of the Criminal Code of Ukraine. The problematic issues of the composition of the criminal offense of intentional destruction or damage to someone else's property are analyzed, the difference between this composition and the intentional destruction or damage to property that has special features (objects of the electric power industry, nature reserve fund, archaeological heritage, weapons, military supplies, official documents, military property, etc.). Intentional destruction or damage to someone else's property, which has special features to be qualified according to the special norms provided for by articles: 113, 1941, 252, 258, 292, 298, 338, 357, 360, 378, 399, 411, 437, 433, 438 of the Criminal Code, is proposed. of Ukraine. On the basis of the analysis of judicial practice, it was proposed that in the case of using an explosive device, for the intentional destruction or damage of someone else's property, such actions of the perpetrator must be additionally qualified under Part 1 of Art. 263 of the Criminal Code of Ukraine. The imperfection of the provisions of the current criminal legislation in terms of the formulation of the qualifying signs of intentional destruction or damage to property was revealed. It has been established that the current legislation of Ukraine on criminal responsibility does not include the concept of a generally dangerous method, arson, explosion, the content of the death of people, serious consequences is not disclosed. The concept of a generally dangerous method and its varieties is proposed. The concept of a generally dangerous method and its varieties is proposed. A generally dangerous method of intentional destruction or damage to property is a method that causes property, non-property, physical damage to an individual or legal entity or creates a real danger of causing such damage to two or more people. In order to avoid unnecessary differentiation of criminal law norms, it is proposed to exclude from the Criminal Code of Ukraine articles 347, 3471, 352, and part 2 of Art. 194 of the Criminal Code of Ukraine to add the sign of intentional destruction or damage to someone else's property in connection with the person's performance of official powers or professional duties.

The study delves deeply into the historical contexts of the countries involved, examining how the idea of cultural heritage and its protection under international law has changed through the years and in various social, economic, and political climates. When preserving cultural assets under public international law, we also consider the humanitarian aspect of this phenomenon. The study examines whether people and groups limit a state's power to act beyond limitations imposed by other states and international organizations. This research further examines the role of international human rights laws in this setting, the preservation of the individual's connection to cultural products, and whether or not an individual becomes a significant player in international law. The study's findings provide conclusive evidence of the pivotal catalytic role that UNESCO and similar international organizations play in the worldwide preservation of cultural heritage. UNESCO is the principal venue for monitoring whether or not states are adhering to international protection principles. Whether or not UNESCO can be effective without ratification processes for cultural preservation has to be investigated more deeply. The study's findings indicate that protecting cultural assets involves a wide range of aspects, including the rights and responsibilities of governments and the rights of cultures. In addition, our research suggests that the ever-evolving international legal system can improve its framework, which is relevant to preserving cultural treasures. [ABSTRACT FROM AUTHOR]

- Abstract
Experimental results for the long-term full-scale climatic testing of aviation polysulfide and VITEF-1B, VGM-L, VIKSINT U-20-99, and VGF-2M polysiloxane grade sealing materials are presented. The testing have been carried out under open conditions of humid tropical climate characterizing Wanning (Hainan Island, China) and moderately warm climate characterizing Gelendzhik. In order to analyze the reasons for decreasing elasticity and strength, the results of similar testing under the conditions of Moscow, Florida, Arizona, and Vietnam have been used. It is shown that under the influence of radiation, destruction and cross-linking reactions occur that lead to the change in the elasticity of the studied materials. [ABSTRACT FROM AUTHOR]

The results of the studies devoted to the consequences of the Kakhovka dam destruction and the empting of the Kakhovske reservoir are presented. The water regime of the lower reaches of the Dnipro River was studied, in particular, the water temperature. The remote sensing data on spatial features of water temperature are given. Significant changes in water temperature are shown both in the lower reaches of the Dnipro River and in the former Kakhovske reservoir. In the first days after the destruction of the dam, due to the mixing, the surface water temperature at the mouth of the Dnipro River dropped significantly. Then the water temperature in the lower reaches of the river approached to that one observed before the destruction. In turn, the former Kakhovske reservoir became a network of river branches and lakes that cannot be compared with the former reservoir. The Dniprovske Reservoir, located upstream, affects the water temperature of this territory, especially the largest branch. [ABSTRACT FROM AUTHOR]

Semianalytical pancake models published in the literature are considered, in which it is assumed that a low-strength, fragmented body, like a liquid, expands during flight in the atmosphere and, while maintaining a certain simple shape and increasing the cross-sectional area, decelerates at much higher altitudes than a strong body. Individual models differ in the rate of increase in the transverse size of the body. For comparison with the models, hydrodynamic simulations of falls of liquid bodies with a diameter of 40 m in the Earth's atmosphere were carried out without taking into account ablation. Such bodies, before they begin to slow down significantly, break up into fragments. Unlike simple models, while the body remains coherent, it can take on very distorted shapes. Comparison of pancake models with the results of hydrodynamic modeling allows us to determine the most suitable models for assessing the behavior of asteroids in the atmosphere and evaluate the assumptions embedded in them. In hydrodynamic modeling taking into account ablation, as shown by the results published in other works, complete evaporation of the body can first occur and, only then, the braking of the vapor jet. In pancake models, complete evaporation means the disappearance of mass and a complete stop of motion. The theoretical basis of these models needs to be revised. [ABSTRACT FROM AUTHOR]

- Abstract
The destruction of inactive medical records is an important aspect inining patient confidentiality and ensuring compliance with regulatory requirements. Although important, many hospitals find it difficult to implement this process effectively. The research is aimed at identifying the factors that caused the failure to carry out the destruction of inactive medical records in hospitals. A mixed method approach is used, combining methods of collecting and analysing qualitative and quantitative data. A survey was conducted among hospital staff members, and semi-structured interviews were conducted with hospital administrators and medical record staff. Research results show that policies and procedures are less clear, training is inadequate, and resources are insufficient.is a major factor inhibiting the implementation of the destruction of inactive medical records as well as indicating that several factors contributed to the failure to destroy inactive health records documents, among others: (1) hospital management does not understand or is unaware of the importance of document destruction; (2) human resources and budget constraints; (3) lack of standard operational procedures for destruction documents; and (4) lack of synchronization and coordination between the medical records unit and other related units. One suggestion that can be given is increased management commitment, the development of standard operational procedures, and the provision of adequate resources to support procedures for the destruction of medical records that are no longer used in hospitals. The findings of this study highlighted the need for hospitals to develop and implement effective policies and procedures for the destruction of inactive medical records, provide adequate training to staff members, and allocate adequate resources to ensure compliance with regulatory requirements.

This article aims to trace the Taliban's motives behind the deliberate destruction of cultural heritage in Swat while also looking into the local's reaction and their relationship with cultural heritage after the conflict. The Taliban insurgents deliberately defaced and dynamited the second largest seated statue of Lord Buddha after Bamiyan in Afghanistan and bomb-damaged Swat Museum. The findings are the outcomes of in-depth interviews and FGDs conducted with locals, key informants from the community, local journalists, NGO representatives, archeologists, and Swat Museum officials. This study demonstrates that the Taliban iconoclastic acts were motivated by their "conflict goal" – the introduction and imposition of Sharia Law in the region. The "specific targeting" of the seated statue of Lord Buddha and the bomb-damaged Swat Museum are considered the principal identifiers of differences, and instrumental in "signalling" strength and commitment to the resisting actors. The polarity in explanations among the locals indicates that the Taliban tactfully manipulated the equivocal understanding of idolatry in Islam. After the conflict, apart from the realization of ownership and pride among the locals, the utmost concerns for them are the protection of cultural heritage and the construction of a religious counter-narrative on the status of idols and statues in Islam.

ENVIRONMENTAL crimes ,CRIME ,NATURE conservation ,NATURE reserves ,ENVIRONMENTAL law - Abstract
The article is devoted to the study of the elements of the objective side of unqualified intentional destruction or damage of territories taken under state protection and objects of the nature reserve fund. Analysis of this element of the composition of the criminal offense provided for in Part 1 of Art. 252 of the Criminal Code of Ukraine, has been carried out, while taking into account the achievements of criminal and environmental law sciences, provisions of regulatory legislation and materials of court practice. The dominant approach is supported, within which the territories protected by the state and the objects of the nature reserve fund are recognized as the subject, and not the place of the commission of the analyzed criminal offense against the environment. Emphasis is placed on the blanket disposition of Part 1 of Art. 252 of the Criminal Code of Ukraine and the need to specify the charges based on this circumstance. The meaning of the concepts of destruction and damage of the territories taken under the protection of the state and objects of the nature reserve fund is revealed; the differences between these concepts are clarified; it is shown how in court practice the elements of a socially dangerous act, indicated in part 1 of Article 252 of the Criminal Code of Ukraine are interpreted alternatively. A scientific proposal has been made to differentiate (in order to improve Article 252 of the Criminal Code of Ukraine) criminal liability for violation of the regime of territories and objects of the nature reserve fund, as well as other key territories of the ecological network of Ukraine, as a result of which the reduction or loss of their special environmental protection has been made, was subjected to critical analysis. At the same time, the perspective of revealing the content of the socially dangerous consequences of the tort under consideration by referring to the concepts of reduction or loss by specific territories (objects) of their special environmental value was noted. The expediency of clarifying part 2 of Art. 252 of the Criminal Code of Ukraine, by taking into account the fact that the destruction or damage of territories and objects, especially those protected by the state, may take the form of inaction, has been pointed out.

Saadaoui, Hayet
- Abstract
This paper experimentally analyzes the effect of incidental emotions on destructive tendencies of the entrepreneurially self-efficacious. Subjects experience an emotion induction procedure that involves a visual stimulus triggering a negative or positive emotion. At this point, they participate in the joy-of-destruction mini-game in which two players simultaneously decide whether they have to reduce the other player's payoff at their own cost. The results show that entrepreneurial self-efficacy could be related to more destructive behavior. Such behavior increases when individuals experience a positive emotional state. These results contribute to the growing literature on the potential downsides of high self-efficacy in entrepreneurial contexts and underscore the importance of considering the role of emotions in shaping economic decision-making.

This article examines the conditions for the formation of the hydroecological regime of the Ivankov Reservoir according to data from complex hydrological, hydrochemical, and hydrobiological surveys carried out in August 2020−2022. The differences in hydroecological characteristics are associated with the peculiarities of weather conditions in the summer seasons. Despite the significant flow of the reservoir, in its bottom layer during prolonged hot weather, the formation of oxygen-free conditions is possible, affecting exchange processes with the bottom, hydrobionts, and methane emissions. The increased bioturbation of bottom sediments (BSs) by benthos under oxygen deficiency activates metabolic processes at the water–BSs boundary, including the release of methane. A strong "bloom" of the reservoir, characteristic of hot weather conditions in 2022, led to a reduction in the specific flux of methane from the surface due to its oxidation with an excess of oxygen in the surface layer.

- Abstract
The aging of a series of aviation fiberglass and carbon fiber reinforced plastics based on epoxy binders after three years of exposure in different climatic zones was studied in terms of changes in compressive and bending strength limits. It has been shown that the destruction of the surface layer of exposed samples reduces the accuracy of measuring their thickness and significantly increases the scatter of the measured parameters. The variation coefficients of strength indicators and fracture loads are compared for the studied materials. [ABSTRACT FROM AUTHOR]

This study investigates the effectiveness of ultrasonic (US) treatment in removing and mineralizing surfactants in wastewater. It examines the complex mechanisms and variables (acoustic conditions, solution temperature, initial dose, etc.) that affect sonolytic processes. The effect of water matrix components (such as salts and the presence of secondary pollutants) on process performance is thoroughly investigated. Various treatments are analyzed through a detailed comparison of synergistic hybridization processes. The study also provides a comprehensive review of current environmental applications and explores potential directions for surfactant degradation using ultrasound. Insightful information is presented to advance sustainable wastewater treatment techniques. The literature review clearly reveals the promising future of sonotreatment for degrading various surfactants under different conditions. The use of multifrequency mechanisms and the integration of other advanced oxidation processes (AOPs) with the US process have significantly enhanced the energy efficiency of the sonochemical system. Additionally, the results highlight the need to focus on developing new sonoreactor designs, identifying degradation intermediates, and hybridizing the sonochemical system under innovative operating conditions.

The article shows the possibility of intensifying the process of producing microcrystalline cellulose via pregrinding of fibrous semi-finished products before hydrolysis. The technological factors determining the grinding of fibrous materials have been considered. The efficiency of the microcrystalline cellulose production process is influenced by the choice of its production technology. For grinding, a semi-industrial disc mill with a tacking with rectilinear and curvilinear knives has been used. Multiphysics models of the flow of fibrous mass in the grinding zone of a disc mill with different knife tacking patterns have been constructed. The morphological properties of the fiber have been measured on the Morfi Neo automatic fiber analyzer after grinding to 65 °SR. The nature of the change in the properties of bleached sulfate hardwood and softwood cellulose has been analyzed. It has been found that it is identical for all degrees of grinding, but the quantitative characteristics change to the greatest extent when grinding softwood cellulose using a tacking with rectilinear knives: the weighted average length of fibers decreases by 17 %, the width – by 14 %; the content of broken fibers increases by 22 %, the content of fines along the length – by 67 % and the fibrillation index – by 1.9 times. A comparative analysis of the values of the degree of polymerization depending on the knife tacking pattern has been carried out. The conditions for producing microcrystalline cellulose after grinding the fibrous mass in a semi-industrial disc mill, depending on the degree of grinding, have been determined. It has been shown that with an increase in the degree of grinding of the fibrous mass from 15 to 65 °SR, the degree of polymerization of microcrystalline cellulose decreases from 272 to 120, the concentration of hydrochloric acid – from 2.5 to 1.5 N and the duration of hydrolysis – from 120 to 90 min. The developed method for producing microcrystalline cellulose makes it possible to reduce the cost of chemical treatment of the fibrous mass (acid concentration, treatment duration and hydrolysis temperature) by 1.5 times.

The problem of obtaining estimates of the strength and resource characteristics of critical engineering infrastructure facilities under operational multiparametric nonstationary thermomechanical impacts is considered. The basic degradation mechanisms in structural materials (metals, alloys) under these influences are identified. The methodology of resource assessment of responsible engineering facilities based on end-to-end modeling of the entire life cycle of the object is substantiated. End-to-end modeling forms a set of computational experiments of different levels of complexity, each of which has its own characteristic features and semantics. From the perspective of the mechanics of the degraded continuum, a mathematical model of the damaged medium has been developed, in which the processes of thermoplasticity and damage accumulation are generated by thermal fatigue. The model describes the effects of cyclic thermoplastic deformation; kinetics of damage accumulation; conditions of macroscopic destruction of the material. The model postulates the representation of the yield surface and the principle of gradiency of the velocity vector of plastic deformations at the loading point. A variant of the thermoplasticity equations describes the main effects in proportional and disproportionate modes. The thermoplasticity model is constructed as a system of “nested” models and contains the forms of equations of the theory of plastic flow under small deformations: various variants of isotropic hardening (ideally plastic material with a constant flow surface, linear isotropic hardening, variant of isotropic nonlinear hardening), various cases of kinematic hardening (linear kinematic hardening, the case of purely nonlinear kinematic hardening) and the general case of translational isotropic hardening. The kinetics of fatigue damage accumulation is described by introducing a scalar damage parameter and based on the energy principles of taking into account the main effects of the damage accumulation process for arbitrary complex loading modes. The condition of reaching the critical damage value is used as a criterion for macroscopic destruction. The relationship between the components of the model is carried out by introducing effective stresses. The paper presents a numerical analysis of the thermal fatigue life of a compact sample with stress concentrators simulating the operation of parts in the nozzle box of a steam turbine of a nuclear power plant. During the analysis, the characteristic features of thermal fatigue in the details of power equipment were studied. It is shown that the end-to-end modeling technology can be effectively used to assess the resource characteristics of power equipment parts under operational loading conditions.

Experimental studies were conducted to refine the theoretical provisions concerning the mechanism and kinetics of penetration for a metal melt consisting of destructive reagents, such as gallium, indium, tin, and zinc (destructive composition), along the grain boundaries in unstressed metal samples. It was experimentally confirmed that the penetration rate of the destructive composition was limited by processes at the liquid phase front, including dissolution of intergranular boundary areas, recrystallization to form solid solution crystals, and opening of new crack areas under the pressure of growing crystals. The experimental findings indicated a significant decrease in the strength of aluminum alloys resulting from the effect of the destructive composition. Analytical dependences and corresponding empirical coefficients characterizing the effects of the destructive composition on structural aluminum alloy elements under tensile loads were derived. These empirical coefficients enable the determination of conditions under which aluminum alloy structures fail under the influence of destructive compounds, considering the tensile stresses. The effect of the destructive alloy on the onset of fatigue damage and the durability of aluminum alloy structures under asymmetric cyclic stresses was examined. Significant reduction in the fatigue strength of aluminum structures under the influence of the destructive composition was experimentally confirmed. [ABSTRACT FROM AUTHOR]

The Ukrainian city of Kharkiv has witnessed terrible destruction during the war with Russia. Many of its inhabitants have fallen victim to enemy shelling. Hundreds of objects and many urban areas turned into ruins. However, the destroyed private houses, high-rises, and even entire neighbourhoods in Kharkiv demonstrate that architecture lives even when it has been involuntarily abandoned, isn't used, and isn't experienced sensually, but is a part of complex systems of things, feelings, and communities. This work focuses on how damaged urban objects and places are being mourned, and how and where new ecological landscapes are being created. To answer these questions, the author went to the damaged places in Kharkiv (the city centre, residential areas, markets, memorials, and the subway) as a clean-up volunteer. Data collection was carried out from April to June 2022. The collected data are considered in the optics of posthumanism, with equal attention to the fragments of concrete, brick walls, broken glass, people and shell craters. [ABSTRACT FROM AUTHOR]

Soil setup has a significant contribution to the performance of jacked piles in natural clays with structure characteristics. In this paper, a series of model pile tests are conducted to investigate the pile setup in structured clays, focusing on the influence of soil structure on time-dependent pile response. Three artificially structured clays are prepared as model soils to avoid the sampling challenge of undisturbed clays. The model tests are capable of modeling pile response through installation, equalization, and loading, and hence the initial structure and stress-induced structure degradation of clays, as well as the following thixotropic effect and reconsolidation of disturbed clays, can be adequately incorporated. Meanwhile, the behaviors of the piles and pile–soil interface are constantly monitored by the measurement system during and after pile installation. The results demonstrate that by increasing the cement content of structured clays from 0 to 4%, the penetration resistance is almost doubled, and the pore water pressure (PWP) and radial stress of the pile–soil interface located 20 cm from the pile toe increase by 1.27 and 1.38 times, respectively. A higher cement content in model soils leads to a quicker dissipation of excess pore water pressure (EPWP) due to the presence of a larger void structure and a smaller zone of damage caused by pile driving in structured clays. The growth rate of the ultimate bearing capacity of piles increases sharply with the cement content. The normal stress of the interface first decreases slightly and then grows dramatically with the mobilized shear stress during static loading tests. [ABSTRACT FROM AUTHOR]

The collision of drops of water and elastic liquids with a thin cylinder (fiber) has been studied. Aqueous solutions of polymers were used as elastic liquids, which simulated the rheological behavior of oral fluid—the main carrier of infections by airborne drops. Water as a Newtonian fluid was investigated to identify the elastic effects when comparing the collisions of Newtonian and non-Newtonian fluids—water and polymer solutions. The flight path of the drop and the cylinder axis are mutually perpendicular. Attention is focused on the difference between the collisions of water drops and drops of elastic liquids. In the experiments, the diameter of the drop was 3 mm, and the diameter of the horizontal stainless-steel cylinders was 0.4 and 0.8 mm. Drops were formed by the slow flow of liquid from a vertical stainless-steel capillary with an outer diameter of 0.8 mm, from which the drops were periodically separated under the influence of gravity. The velocity of the drop before the collision was determined by the distance between the end of the capillary and the target (cylinder); in the experiments, this distance was 5, 10, and 20 mm. The velocities of falling drops before impact were estimated in the range of 0.2–0.5 m/s. The collision process was monitored using high-speed video recording methods with frame rates of 240 and 960 Hz. Water and aqueous solutions of polyacrylamide with a molecular weight of 11 million and concentrations of 100 and 1000 ppm were used as test liquids. Experiments have shown that, depending on the height of the drop and the concentration of the polymer, various drop collision scenarios are possible: (1) short-term rebound of the drop from an obstacle, (2) braking and stopping the drop on the obstacle, (3) flow of the drop around a cylindrical obstacle while maintaining continuity and continuing free flight, (4) disintegration of the drop into two secondary drops, each with its own history of subsequent flight.

After the gas drainage borehole is formed in the coal seam, its stress deformation process is a creep process without the influence of mining. By arranging boreholes on coal samples and carrying out creep loading test of porous coal through rock mechanics testing machine, the creep process of boreholes in actual coal seams is simulated. The results show that the creep loading test results of drilled coal are quite different from those of conventional loading. Creep loading produces large deformation due to rheological and aging characteristics. Compared with non-porous coal, the yield of drilled coal occurs earlier and the yield platform is wider during creep loading. Also, the larger the borehole diameter, the deeper the borehole depth, and the lower the peak stress. The up dip angle is easier to destroy than the down dip angle. Compared with hard coal, soft coal produces greater deformation under smaller peak stress. The research results have guiding significance for drilling gas drainage in the soft coal seam.

This paper presents the results of frequent observations of the intensity of production processes in the surface water layer in the Krasnovidovo pool of the Mozhaysk Reservoir from June 17, 2018 to September 26, 2018. Measurements were carried out using an automatic production meter developed by A.V. Goncharov, a system of water temperature recorders, subaquatic illumination, photosynthetically active radiation (PAR), and meteorological characteristics. No statistically significant relationship between gross production and the main predictors determining its value have been recorded throughout the measurement period, while its relationships with water temperature and illumination proved to be statistically significant for the period with no limitation of biogenic elements and for the autumn cooling period. According to the results, an important factor determining the amount of gross production is dynamic mixing. [ABSTRACT FROM AUTHOR]

- Abstract
The recent earthquake in the Kahramanmaraş region on 06.02.2023 in Turkey and Syria had a magnitude of Mw 7.8, its intensity in some areas of Turkey reached XI points on the modified Mercalli scale. The earthquake caused catastrophic consequences, leading to the death of more than 52,800 people, as well as numerous destructions of infrastructure. The article analyzes the consequences of the appearance in the seismogram of an earthquake of an unusually strong delta pulse, associated with the arrival of a horizontally polarized S-wave. The issues of creating seismic protection systems against high-intensity delta-shaped pulses are discussed. [ABSTRACT FROM AUTHOR]

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder that is commonly diagnosed in women of reproductive age. The reported incidents of PCOS are drastically increasing every year worldwide, however, the etiology of PCOS is still not fully comprehended. A traditional herb such as Nigella sativa (NS) is being consumed as an alternative to modern medications to manage the signs of PCOS. The effectiveness of NS against PCOS signs and symptoms is being widely published, but studies focusing on its effect on ovarian dysregulations are limited. Hence, this review was written to provide an updated summary of NS and the ovaries of PCOS subjects. This review gathered publications from studies conducted in an in vivo and clinical trial settings and is anticipated to be a reference for future research involving NS and PCOS subjects.

The article analyses the aspect of the influence of colonial policy on the destruction of national cultural identity, in particular, on the destruction of traditional religious objects. The problem is traced on the example of the colonisation of Algeria by France, which resulted in the purposeful destruction and reconstruction of historical mosques, on the example of the colonisation of Ukraine by the Russian Empire, which prohibited the construction of churches in the Ukrainian style, and later by the Soviet Union, and on the example of the modern Russian-Ukrainian war, when Russia deliberately destroys all religious buildings, even those subordinate to the Russian-backed Church. Religious buildings, as the legacy of a given nation's material culture, should be placed under conservation, as they are treasure to all of humanity. Examples of such positive thinking do exist. The study is complemented by the photofixation of the destruction of temples during the Russian-Ukrainian war, taken directly in the combat zone. The purpose of the study is to analyse the negative effects of colonial policy on the preservation of the national identity of religious objects and to propose ways to overcome them.

The article is devoted to the current topic of the destructive impact of wars on the state of historical and cultural heritage. The vulnerability of architectural monuments to the chaos of war was evidenced by the recent events of the war in Ukraine. The thesis of the article is illustrated by examples of the destruction of specific objects in Chernigov. As any war comes to an end and the question of reconstruction and restoration of the destroyed is raised, the experience of rebuilding the Old Town in Warsaw, which officially introduced a new direction in the restoration activity -- restitution, is analysed, and the fate of museum collections in Slovakia is also analysed. The presented good conservation practices and their results in the reconstruction of Warsaw's historical monuments can be used in the development of detailed action plans for the reconstruction of objects related to the national heritage of Ukraine. It also seems expedient to use the principles of urban logistics when analysing and designing, and then implementing the assumptions of the operation of reconstructed historic cities.

OXALIC acid ,WASTE treatment ,WASTE management ,DECONTAMINATION (From gases, chemicals, etc.) ,MANUFACTURING processes ,HYDROGEN peroxide ,ENVIRONMENTAL risk - Abstract
Oxalic acid is encountered within industrial processes, spanning from the nuclear sector to various chemical applications. The persistence and potential environmental risks associated with this compound underscore the need for effective management strategies. This article presents an overview of different approaches for the destruction of oxalic acid. The study explores an array of degradation methodologies and delves into the mechanistic insights of these techniques. Significant attention is channeled towards the nuclear industry, wherein oxalic acid arises as a byproduct of decontamination and waste management activities. An integral aspect of decommissioning efforts involves addressing this secondary waste-form of oxalic acid. This becomes imperative due to the potential release of oxalic acid into waste streams, where its accommodation is problematic, and its capacity to solubilize and transport heavy metals like Pu is a concern. To address this, a two-tiered classification is introduced: high concentration and low concentration scenarios. The study investigates various parameters, including the addition of nitric acid or hydrogen peroxide, in the presence of metallic ions, notably Mn
2+ and Fe2+ . These metallic ions are common components of effluents from metallic waste treatment. Additionally, the impact of UV light on degradation is explored. Investigations reveal that at high concentrations and with the influence of hydrogen peroxide, the presence of metallic cations accelerates the rate of destruction, demonstrating a direct correlation. This acceleration is further enhanced by exposure to UV light. At low concentrations, similar effects of metallic cations are observed upon heating the solution to 80°C. The rate of destruction increases proportionally with hydrogen peroxide concentration, with an optimal oxalic acid to hydrogen peroxide ratio of 1:100. Interestingly, a low-power UV light exerted no discernible effects on the destruction rate; heating alone proved sufficient. In essence, regardless of concentration, the degradation of oxalic acid with hydrogen peroxide experiences acceleration in the presence of metallic ions such as Mn2+ and Fe2+ .

This article offers an examination of the Japanese postwar writer Takeda Taijun's concept of destruction (metsubō) and his view of the sekai, or "world," as a theoretical tool against Japanese imperialism, and potentially also for a transnational history. It first examines Takeda's wartime book-length essay entitled Sima Qian: The World of Shiji (Shiba Sen: Shiki no sekai, 1943) to highlight Takeda's conceptualization of space (kūkan) that anchors his figuration of the sekai. According to Takeda's reading of Shiji, the structure of the sekai suggests a world without a hegemonic center that could survive its fate of destruction, which is considered by many Takeda scholars to be a prophesy of the bankruptcy of Japanese imperialism. It then points out the focus on the totality of the sekai in Takeda's Sima Qian, in which the writer looks at history only from a retrospective standpoint and as a bystander. After the first section follows a reading of Takeda's short story 'Judgment' ('Shinpan,' 1947) and his last work Shanghai Firefly (Shanhai no hotaru, 1976), in which this article not only observes the trajectory of the evolution of Takeda's concept of the sekai as an absolute continuity that feeds on the absolute destruction of its parts, but also recognizes how Takeda's concern of the individual in the sekai has been developed over the years. Finally, it discusses how a transnational history might be possible based on a scrutiny and critique of Takeda's concept of the sekai. [ABSTRACT FROM AUTHOR]

In this work, the process of decomposition of 2,4-dichlorophenol (2,4-DCP) vapor under the influence of atmospheric pressure DBD in oxygen was studied. The studies were carried out in two modes: with a catalyst (natural vermiculite doped with zirconium) and without it. A number of basic characteristics of the catalyst were assessed. The rates and effective rate constants of sorption processes, as well as decomposition processes in plasma and plasma-catalytic systems, were determined. Based on these data, the energy efficiency of the decomposition process was calculated. The data obtained suggested that the initial stage of decomposition is the reaction of interaction of electrons with pollutant molecules. The catalyst has been shown to speed up the decomposition process, increase energy efficiency and the conversion of 2,4-DCP to CO
2 molecules, and prevent the formation of condensed products on the reactor walls. The work estimates the carbon and chlorine balances before and after treatment, which reach a maximum of 99 and 60%, respectively. It was also shown that the catalyst retains its activity for at least 7 h of continuous operation. [ABSTRACT FROM AUTHOR]- Published

The verb שׁמד is a prominent verb of destruction that appears throughout the Hebrew Bible (HB). It is well represented in both Dtn-Dtr and the Prophetic Books. Many verses related to the conquest of Canaan and the exile feature this verb. Relevant scholarly literature also indicates that some elements of its meaning and usage remain obscure. All this makes it worthy of investigation. The last few decades have seen a rise in the utilisation of cognitive linguistics (CL) for the exegesis of the HB. A review of scholarly literature did not identify any robust attempt at utilising CL to gain insight into the meaning of שׁמד. In this study, frame semantics (FS) along with several other CL methodologies are used to gain greater insight into the semantic force of שׁמד in the HB. Three major discoveries were made. (1) While there usually are severe fatalities, all-encompassing fatality (i.e. annihilation) is not at the semantic core of שׁמד. Rather, decimation is the idea. (2) The destruction envisaged by שׁמד is conceptualised as removal from a location, whether dispossession or extermination. (3) Some insight was gained into the obscurity of when שׁמד takes במות as an object. Intradisciplinary and/or interdisciplinary implications: This study traverses the fields of CL, Semitics, Biblical Studies, and Biblical Theology. It utilises CL to gain greater insight into a Hebrew verb. This insight enabled more accurate exegesis of the HB. These exegetical findings have implications for Biblical Theology, especially divine judgement and the conquest of Canaan.

The new method of time-averaged speckle images and the well-known method of speckle-field interference studied the development of plastic deformations occurring during multicycle fatigue of structural steel. The correctness of strain determination by the new method is evaluated by comparing the data obtained by the two methods. Two optical systems including laser modules with different wavelengths were investigated. The proposed optical system allows to determine the components Δuy, Δuz of the relative displacement vector of two surface points located at a distance (measurement base) Δs = 66 μm. The known scheme makes it possible to describe deformations by the traditional method on the base of 470 μm. The object of study was a flat specimen made of 09Г2С steel with two side notches. Fatigue tests were carried out on a resonance-type machine at different cycle amplitudes. It is shown that at all cycle amplitudes the development of plastic deformations occurs by the mechanism of cyclic creep. There is a good correlation between the data obtained by two different speckle methods. At the same time, the strain estimated by the new method is in some cases an order of magnitude higher than the strain calculated by the known method. Obviously, this is due to the existence of local smallsized (of the order of 101 μm) strain areas which cannot be measured by conventional methods. The ultimate tensile strain Δuy/Δs calculated by the new method is of the order of 10–1, which coincides with the similar strain occurring in tensile testing of standard specimens. The results obtained by the new method justify the need of developing sensors and nondestructive testing devices of a new generation, allowing to estimate the time to fatigue crack initiation by the rate of change of physical quantities and by their limit values.

The parameters of a high-current electron beam extracted from the self-focusing zone through a hole in the anode into a vacuum chamber are investigated. The beam parameters were determined from the measurement of the spatial distribution of destruction and glow arising in polymethyl methacrylate samples installed at different distances from the anode (electron beam autographs). The formation of two electron beams—a self-focused with a high energy density, propagating along the axis of the cone facing the base to the anode with an apex angle of ~7° and a high-energy beam of low density, propagating in a hollow truncated cone and surrounding self-focused, was found. The oscillograms of the current and the energy of the electron beams were measured. [ABSTRACT FROM AUTHOR]

Entrepreneurial action can be directed toward identifying, generating, and exploiting potential business opportunities that can cause harm to others. Over and above the "rules of the game" of the economic system, we theorize on destructive entrepreneurial actions that result from entrepreneurs' impaired regulation of their decision making. Specifically, we build on the entrepreneurial action literature and draw on regulation theories of goal attainment and moral disengagement to develop an impaired-regulation model of destructive entrepreneurial actions. This model contributes to the entrepreneurship literature by providing new insights into (a) why some entrepreneurs are more susceptible to engaging their ventures in destructive entrepreneurial actions, (b) everyday entrepreneurs (the "who") engaging in destructive entrepreneurial actions (i.e., the "how" and "why"), and (c) when and why some entrepreneurs respond to their destructive entrepreneurial actions by becoming repentant do-gooders while others grow into serial offenders.

Despite its form, the term damnatio memoriae was never utilized in antiquity. It is invoked in relation to the Roman world to denote a series of intricate attacks on the memory of vanquished adversaries. This encompasses various public and political actions such as the obliteration of statues and monuments, as well as the effacing of inscriptions. Numerous literary instances, however, indicate that it served not merely as a means of annulment and oblivion, but as a tool for vilifying an enemy, ensuring they were remembered in the most negative light possible. In such a process, the individual's name becomes deeply entwined. [ABSTRACT FROM AUTHOR]

This article starts from the discussion and reflection on contemporary scenographic production and its expanded practices to present the concept of an expanded scenography from the Global South, whose aesthetic, spatial, and language principles include different sociocultural epistemologies in diverse countries, in its various manifestations. Based on the concept of epistemologies of the South, presented by sociologist Boaventura de Souza Santos, I seek to approach a scenographic epistemology from the South, whose perspective is connected with a process of extraction and destruction, the street and unconventional spaces, environment, climate and the ritual, including examples from Latin America, Asia, and African continents.

Purpose. To establish influence regularity of sand, water and clay preparation conditions on vitability of frozen mixtures made from combinations of these components and to increase the castings quality in foundries, as well as to improve technologies for artificial freezing of soils for underground constructions. Methodology. In this research, sand, clay, and water are used. Ice quality is estimated visually after water freezing at -15 °C in glass tubes. Frozen mixtures’ vitability at -15 °C is studied on beam-type samples. As indicators of survivability, the time to 1 mm bending of samples on supports and the time to their destruction are accepted. The time is recorded with a stopwatch, the temperature with an alcohol thermometer, the mass with electronic scales and the deflection arrow with a clock-type indicator. Findings. The presence and amount of water-soluble impurities in rare water significantly influence the nature, size and distribution of gas bubbles in ice, as well as frozen sand-water mixtures vitability. Frozen mixtures’ survivability increases with water content in them increasing, and, for sand + water mixtures, survivability is maximum if ice has a homogeneous structure. Among mixtures with clays, the mixture with non-swollen kaolin clay has the greatest vitability. Regarding survivability, recommendations for manufacturing products from frozen foundry mixtures have been developed. Originality. For the first time, deformation change kinetics (bending arrows) under the influence of beam-type samples’ selfmass from mixtures of quartz sand and water and quartz sand, clay and water frozen at -15 °C, which have been previously prepared in different ways, have been investigated. Insights into the influence of various factors and ice quality on the vitability of frozen mixtures have been further developed. Practical value. The obtained results can be useful for expanding ideas about natural frozen soils’ behavior during their cyclic temperature changes, soils artificially frozen during mine shafts elaboration, escalators’ and junctions’ tunnels, etc. when constructing subways. In foundries, the developed recommendations will reduce technological losses and will improve casting quality made using frozen casting molds and cores from sand-water or sand-clay-water mixtures, castings’ patterns and their pouring systems from sand-water mixtures.

In this paper, we consider issues of the kinetic theory of strength and the effect of temperature and force factors on the damage accumulation in materials. Phenomenological models of the formation and propagation of defects structures determine the strength, anticorrosion, tribological properties of materials, and the nature manifestations of destruction processes during operation. The selection and verification of a material behavior model makes it possible to apply reasonably methods to improve their performance and protect against corrosion. [ABSTRACT FROM AUTHOR]
