Published: June 2024

Несмотря на более высокий уровень урожайности при интенсивном возделывании, дополнительные затраты на обработку почвы, удобрения и пестициды окупаются только в годы с усиленным развитием патогенов, поэтому биологизированные технологии будут экономически более выгодны и экологически безопасны. Интенсивную обработку почвы проводят и применяют химические средства защиты растений в зависимости от результатов почвенной и растительной диагностики, биологических особенностей сорта и при превышении экономических и экологических порогов вредоносности. При этом использование природоподобных технологий связано не только с удорожанием энергоносителей, но и со значительной потерей плодородных свойств почвы из-за необоснованного применения химических препаратов. Применение такого рода технологий возможно при более полном и эффективном использовании генетического потенциала современных сортов сельскохозяйственных культур, созданных без участия ГМО, почвенно-климатических ресурсов и соответствующем уровне материальных и других затрат.

Землепользование на рациональной основе строится на принципе эффективного использования пашни: выбор оптимальной системы обработки агрочерноземов; соблюдение научно обоснованных технологий выращивания зерновых культур; интенсивное использование систем удобрений. Объектами исследования являлись почвенные разрезы на пробных площадях пашни южной группы районов Красноярского края. Общая площадь сельскохозяйственных угодий составляет 1037,3 тыс. га, в том числе пашни — 549,6 тыс. га. Черноземы (оподзоленные, выщелоченные, обыкновенные, южные) занимают 83,2 %. Агрочерноземы — черноземы, используемые человеком в аграрной деятельности, которая приводит к изменению их природных свойств. Общие физические свойства агрочерноземов (подзолистых, выщелоченных, обыкновенных) зависят от их особенностей и проявления закономерностей: удельный и объемный вес увеличиваются вниз по профилю с уменьшением органической части в почве. Объемный вес выщелоченных и обыкновенных черноземов, по сравнению с оподзоленными, увеличивается медленнее из-за проявления процесса иллювиирования. Наблюдается высокая максимальная гигроскопичность (11,0 – 11,9 %) в горизонте Ap и устойчивая зависимость между физическими свойствами почв и их структурно-агрегатным составом, которая является одним из факторов, определяющих их плодородие.

Integrating Focal Vulnerability into Trust Research
Authors: Hamm Joseph A. , Möllering Guido , Darcy Kathleen
Published: June 2024

Trust—most often defined as the trustor’s willingness to accept vulnerability—matters across almost every facet of modern life. Significant bodies of research have been devoted to understanding the nature and dynamics of the construct, but much less work has directly considered the vulnerability at the core of its definition. The current article addresses this gap, elucidating the concept of focal vulnerability as the portion of the trustor’s individualized, total potential for experiencing harm that is perceived, relational, and contemporaneous with their assessment of trust. We then position this concept as the vulnerability that a trustor is, by definition, willing to accept. Following work in other literatures, we consider the dynamics of focal vulnerability by exploring the systematic ways in which it is likely to vary. We then argue that this variability can be meaningfully captured by assessing the extent to which the trustor experiences felt vulnerability, an aversive recognition of their potential for experiencing harm. We conclude by exploring the implications of this argument and outline several untested assumptions that are ripe for future research.
Warung Kopi dan Santri; Religion in Secularcapes
Authors: Faiz Muhammad Muqronul , Hadziq Abdulloh
Published: June 2024

The interaction between coffee shops and Muslims has led to studies on history, philology, symbolic interaction, and pluralism. Although research on coffee shops and Muslims has emerged, there is still no one who looks at it from the perspective of religioscapes. This study aims to examine the interaction of santri in public spaces and how the impact is caused from the perspective of religioscapes. This research uses Spradley's ethnographic method, intending to analyze the phenomenon of santribehavior in coffee shops in detail. Researchers become part (live in) so that they can elaborate on the various meanings of ways of thinking and behaving in understanding human clumps. Claudia Seise's concept of Religioscapes is used as an analytical method in describing the religious state of santri in Warung Kopi Yogyakarta. This research shows that religious practices that occur in secular places, including the recitation of shalawat burdah and the recitation of yellow books on the themes of fiqh, nahwu, and tasawwufthat are routinely carried out by santri, can influence other individuals, especially from non-santri, resulting in religion in secularcapes. Coffee shops as places that are initially neutral/secular become spaces for certain religious practices, which we call religion in secularscapes. This research implies that santri can form new religious spaces, or new religioscapes in secular places, where neutral spaces become sacred and religioscapes of this model do not have the main authority, but have diffuse authority.
ASSESSMENT OF THE INFLUENCE OF MINING-GEOLOGY AND MINING-TECHNICAL FACTORS ON THE STABILITY OF MINING WORKS
Authors: Nosach Oleksandr , Petrenko Andriі , Isaienkov Oleksandr , Kipko Oleksandr
Published: June 2024

Purpose. Analysis of the impact of mining-geological and mining-technical factors on the stability of excavation site products.

Methods. Analysis of studies of the state of the geotechnical system “massif-mining-protection structure” analytically, in laboratory and production conditions.

Results. The analysis of the factors affecting the stability of the excavation workings showed that the mining factors associated with the parameters of the workings (width of the workings, shape of the cross-section of the workings, the scheme of erection of support anchors, type of permanent support of the workings) come to the fore: the speed of the face movement and the parameters of the workings protection. The effect of a high speed of face advancement on the mechanism of bearing pressure on the edge part of the massif can be compared to the rolling of a massive sea wave, wide at the foot but with a lower crest height. At a high speed of its movement, there is no pronounced area or “peak” of additional loads. Among the mining and geological factors, the tectonic structure of the deposit, the depth of development and, as a result, the stress state of the rock mass are of great importance. The physical and mechanical properties of rocks are of subordinate importance, with the influence of layering, fracturing and water cut being particularly noticeable. The relationship between the convergence of side rocks in the working faces and the speed of the face advancement is periodic. The minimum displacement values are observed when the number of coal mining cycles per day is a multiple of three. It can be assumed that this pattern is due to the influence of tidal fluctuations and coincides with even harmonics.

Scientific novelty. Based on the analysis, it was found that when addressing the issue of increasing the stability of excavation workings, it is necessary, first of all, to pay attention to mining factors (width of the workings, shape of the cross-section of the workings, scheme of erection of support anchors,) the speed of advancement of the cleaning face, parameters of the protective elements of the workings at the face-strip junction, and link them to mining and geological conditions, especially the tectonic structure of the deposit and the depth of its development.

Practical implication. When determining the parameters of the geomechanical system “massif-mining-protection structure”, it is necessary to take into account the parameters of the production, the speed of the cleaning pit, the protection parameters of the production with the cohesive tectonic structure of the deposit, the depth of development and the physical and mechanical properties of the rocks.

APPLICATION OF COMBINATORY OPTIMISATION METHODS FOR DESIGN OF MINING PRODUCTION PROCESSES WITH LIMITED RESOURCES
Authors: Khorolskyi Andrii
Published: June 2024

Purpose. To develop a new approach to the design of mining production processes with limited resources.

Methods. Combinatorial optimisation methods were used to develop a new approach. The problem of designing technological processes can be solved by interpreting the problem “knapsack problem” with a private solution “backpack 0-1”. Dynamic programming algorithms are used to find the optimal solution.

Findings. A new approach to the design of mining production management processes with limited resources has been developed. If the target goal is to obtain the maximum effect at minimum costs, then the direct run method is used. If there are restrictions on bandwidth, energy characteristics, specific cost, then the reverse run method is used. In the final part of the study, the proposed approach was verified. The task consisted in the development of recommendations regarding the choice of the structure of the technological chain of the cleaning pit under the given technological and mining-geological development parameters. The amount of specific production cost was imposed as a limitation. As a result of solving the design problem by the reverse run method, recommendations for replacing the cleaning equipment were developed. This made it possible to ensure the specified level of productivity and reduce the unit cost by 10.6%. The use of combinatorial optimisation methods made it possible to obtain an optimal solution in the field of given parameters.

Originality. The scientific novelty of the work consists in establishing regularities in the formation of the efficiency of mineral deposit development processes. For the first time, combinatorial optimization methods were used to design the processes that accompany the development of mineral deposits, and the scope of their application was determined, as well as a number of dynamic programming tasks and algorithms were formalised: backtracking, spanning tree.

Practical implication. Verification of the developed approach was carried out in relation to the design of mining production processes with limited resources. The obtained approach makes it possible to find optimal solutions under the constraints set at the design stage. As limitations can be: throughput capacity of the transport chain, energy characteristics of technological processes accompanying mining, specific cost of mining, etc. The design problem can be solved in a direct order – if the objective function is to maximise the parameter, or in the opposite way – if there are restrictions.
ASSESSMENT OF STABILITY OF PREPARATORY MINE WORKINGS WITH CAST STRIP PROTECTION
Authors: Chepiga Daria , Hnatiuk Vitalii , Pidhurna Olha
Published: June 2024

Purpose. To assess the stability of the preparatory mine workings with the method of protection with cast strips in order to ensure safe working conditions in the mining areas of the coal mine.

Method. A comprehensive approach was used in the research, which included the analysis and generalisation of theoretical and experimental research on this problem, a mine experiment in the conditions of the Pokrovske Mining and Metallurgical Mining and Processing Plant, and the processing of experimental data.

The results. As a result of the conducted research, an assessment of the stability of the preparatory mine work with the method of cast strip protection was established. Deformation processes in the coal massif around the preparatory production were considered during its unloading under the conditions of the static load of the protective structure. The analysis of the change in the increase in displacement of the roof indicates that the security structure is deformed under loading by external forces. As the cleaning hole moves, when the length of the preparatory work increases, the displacement of the side rocks on the contour increases. Depending on the position of the cleaning hole, the cross-section of the preparatory work is reduced due to the effect on the fastening of the pressure of the loaded rocks.

It was established that within the limits of the deformation resource of the cast strip, when its relative deformation is within 0≤ε≤0.3, the loss of the cross-sectional area of ​​the preparatory work does not exceed 15%, which ensures safe working conditions for miners at the excavation site. In conditions where the relative deformation of the security structure increases (0.35≤ε≤0.65), there is a loss of the load-bearing capacity of the security structure, which is accompanied by an increase in the displacement of the roof on the contour (more than 40 mm) and deformation of the fastening. At the same time, the loss of the cross-sectional area of ​​the product is more than 40-42% and the level of the threat of roof collapse is approaching a critical state.

Scientific novelty. A type of functional dependence has been established between the change in the relative deformation ε of the protective structure, which is under static load in the coal massif, and the cross-sectional area S (m2) of the preparatory work, according to which its condition is evaluated according to the length of the excavation site.

Practical meaning. The use of cast strips for the protection of preparatory mine workings allows ensuring their operational condition within the limits of the deformation resource of protective structures.

Keywords: preparatory work, operating condition, side rocks, protective structures, roof displacement, deformation, work safety.

Authors: Yavorska Olena , Ikonnikov Maksym , Lantukh Dmytro , Sushko Nadia , Sosuliev Yehor
Published: June 2024

Purpose. To assess the occupational risk of a lone worker.

Methodology. To assess the occupational hazard risks of lone workers, the BOWTIE method was used in accordance with the requirements of DSTU EN IEC 31010:2022 “Risk Management – Risk Assessment Methods”, which allows describing and analysing the options for the development of hazard risks from the beginning of the identification of hazardous factors that increase the probability of a hazardous event to the severity of the consequences, combining the fault tree and the event tree in a graphical form.

Research results. An assessment of the occupational risks of a lone worker was carried out, taking into account the impact of hazardous factors on increasing the likelihood of a dangerous event, including organisational, psychosocial, technical and ergonomic factors that emphasise the peculiarities of his or her work. The author analyses the current labour protection legislation on the regulation of the work of a lone worker, which made it possible to identify the relevant restrictions on briefings and the transfer of the relevant production task. As an example, the author establishes that the level of occupational risk of a security guard is unacceptable due to the significant impact of psychosocial and ergonomic hazards. The article provides recommendations for the development of occupational safety programmes for lone workers, which include mandatory questioning, risk assessment, analysis of the causes of existing dangerous events, and provision of a system for monitoring the performance of work by lone workers.

Scientific novelty. The relationship between the risk of danger and dangerous factors that are characteristic of the work of a lone worker, which allows identifying the weaknesses of professional activity, is established.

Practical significance. An algorithm for assessing occupational risks has been adapted to analyse the hazards that affect the production activities of a lone worker and general recommendations have been developed to reduce the likelihood of a dangerous event – injury to a lone worker – by introducing a work monitoring system.
USE OF THERMOCATALYTIC SENSORS IN SYSTEMS FOR MONITORING WORKING CONDITIONS AT OIL AND FUEL FACILITIES
Authors: Holinko Vasyl , Zabelina Valentyna
Published: June 2024

Purpose. To substantiate the possibility of using thermocatalytic sensors in systems for monitoring working conditions to control the content of gasoline vapours in the air of the working area of oil and fuel facilities.

Research methods. The paper applies analytical methods for studying the processes occurring in thermocatalytic sensors, which are based on the basic provisions of electrical engineering and the theory of heat and mass transfer, evaluation and generalisation of research results.

Results. The use of thermocatalytic sensors in systems for monitoring working conditions to control the content of gasoline vapours in the air of the working area of oil and fuel complex facilities is substantiated. It is shown that the sensitivity of thermocatalytic gas analyzers, which is necessary to control the content of gasoline vapours within the maximum permissible concentrations (MPC), can be ensured by selecting the sensor power mode with voltage stabilisation on the comparative element, carrying out periodic automatic checking and correcting zero readings of gas analyzers.

Originality. It consists in the use of a method of feeding a thermocatalytic sensor with voltage stabilization on a comparative sensing element, which ensures a stable temperature regime of thermoelements, and improving the method of monitoring and correcting zero readings of thermocatalytic gas analyzers by reducing the sensor supply voltage to the value at which the oxidation reaction of gasoline vapours does not occur on the working thermoelement of the sensor, which consists in the calculated determination of the zero displacement of the measuring bridge in the operating mode of the sensor power supply and taking into account the value of this displacement when determining the current value of the gasoline vapour content.

Practical value. The proposed solutions to increase the sensitivity of gas analyzers create conditions for the use of relatively simple, stable and cheap thermocatalytic sensors in the systems for monitoring working conditions to control the content of gasoline vapours in the air of the working area of oil and fuel complex facilities, which creates the prerequisites for the introduction of modern information technologies in the field of health and safety of workers.

INCREASING THE EFFICIENCY OF SUPPLYING COMMUNITIES WITH WATER RESOURCES THROUGH THERMOSTABILIZATION OF OPEN WATERS
Authors: Kostenko Viktor , Tavrel Maryna , Bohomaz Olha
Published: June 2024

Purpose. Increasing the efficiency of providing communities with thermostabilised water by using an airlift aerator in open water bodies.

Method. Theoretical analysis of the advantages and disadvantages of the currently existing methods and means of water purification, modelling using the demo version of the ANCIS program, using the finite element method, the temperature dynamics of the water column in the hot period of the year and when using a water aeration and thermostabilization installation.

Results. In this publication, the authors consider increasing the efficiency of providing communities with water resources of appropriate quality through thermal stabilisation and aeration of water. The paper provides an overview of the main methods of water purification and analyses their purification efficiency. Based on the analysis, the most effective and economical method is water aeration. Aeration makes it possible to mix water layers with a higher temperature with cooler layers, thereby reducing the average temperature of the water. Also, a similar method allows you to additionally saturate the water with oxygen, preventing the excessive formation of cyanobacteria and the death of beneficial hydrobionts of reservoirs. To reflect the effect of turbulent mixing of water masses by an aerator, simulation was carried out using the demo version of the ANCIS program using the finite element method, which consists in finding the solution of integral and differential equations in partial derivatives. The simulation results showed that the thermocline is destroyed during the mixing of water masses and the water temperature cools from 25оC to 22оC. Such a temperature slows down the excessive formation of unwanted hydrobionts and ensures the free dissolution of oxygen in the water. In practical use, in natural surface reservoirs, it is proposed to use several patented airlift-aerator units. This development is effective for low-water reservoirs, mixes water layers with different temperatures, and additionally saturates with oxygen.

Scientific novelty. The justification of the feasibility of using thermostabilization installations in surface reservoirs for the possibility of providing urban communities with high-quality water resources was carried out, the process of thermocline destruction by forced mixing of water masses was simulated.

Practical significance. On the basis of simulated data, using the demo version of the ANCIS program, it is possible to evaluate the effectiveness of the proposed method of thermostabilization of water for the needs of communities with little water supply.

Key words: thermostabilised water, thermocline, water resources, airlift aerator, open reservoirs.

Waterfall Method In Designing A Web-Based Waste Payment Information System (Case Study: Calincing Bukit Valley Housing Rt04/Rw008)
Authors: Agus Heri Yunial
Published: June 2024

Valley Bukit Calincing Housing Exchange RT. 04 RW. 08 Bogor City is a housing complex that requires every resident to pay monthly waste fees. Payment of waste fees is payment of waste fees made by the treasurer who visits residents' homes to collect by giving a payment card to each resident and recording it again in the ledger. For reports, we still use Microsoft Excel. Because payment recording still uses Microsoft Excel, files on the laptop or PC can be lost or even accidentally deleted. Meanwhile, if it is recorded in a book, the book could be damaged/lost. The method that will be applied for this research is using Waterfall which has sequential stages starting from analysis, design, coding, testing and supporting stages, but in this research it only reaches the testing stage. Meanwhile, for the system development method using the OOAD method, a web-based application was created which is the right choice to simplify the treasurer's work in managing and managing waste fee payments. With this system, it can make it easier for residents to pay waste fees on time and reduce residents who like to pay past due dates because they are always reminded via email notifications sent by the treasurer so that the treasurer does not need to come to residents' homes to collect the waste fees. And with this waste fee payment information system, it makes it easier to manage the treasurer's waste fee payment reports.

Authors: Gokarneshan N.
Published: June 2024

Traditional wound dressings require frequent replacement, are prone to bacterial growth and cause a lot of environmental pollution. Therefore, biodegradable and antibacterial dressings are eagerly desired. In this paper, gelatin/ZnO fibers were first prepared by side-by-side electrospinning for potential wound dressing materials. The morphology, composition, cytotoxicity and antibacterial activity were characterized by using Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), particle size analyzer (DLS), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), thermogravimetry (TGA) and Incucyte™ Zoom system. The results show that ZnO particles are uniformly dispersed on the surface of gelatin fibers and have no cytotoxicity. In addition, the gelatin/ZnO fibers exhibit excellent antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) with a significant reduction of bacteria to more than 90%. Therefore, such a biodegradable, nontoxic and antibacterial fiber has excellent application prospects in wound dressing.

Recent small trials involved limited number of patients shown an increased risk of Venous thromboembolism in HIV patients, pulmonary thromboembolism being one of them. Patients with HIV infected and thromboembolism may have a typical clinical presentation mimicking common cold such as fever, cough and dyspnea. We describe case report of patients with symptom mimicking pneumonia who presented with acute pulmonary embolism and treated then subsequently diagnosed as having HIV infection.
Radiation-induced eye impairments
Authors: Hristov Nikolai
Published: June 2024

The problem of the impact of ionizing radiation on eye structures is one of the most important and topical in radiobiology. Knowledge of tissue radiosensitivity and induced tissue changes in the eye is essential for understanding the nature of radiation damage and the behavior of medical professionals. In this publication, the early and late determined radiation-induced impairments of the eye are presented as a result of radiotherapy or radiation incidents. The risk factors determining post-irradiation eye reactions, pathophysiological mechanisms, clinical picture, diagnosis, prevention, and new approaches in therapy are presented. We found that the typically found radiation-induced eye impairments are those of the eyelids – dermatosis and madarosis, conjunctiva – acute conjunctivitis, varied damage to the lacrimal apparatus, cornea – edema and ulceration, iris – rarely inflammation or neovascularization, sclera – rarely atrophy or necrosis, eye lens – cataract, retina – characteristic retinopathy, and optical nerve – rarely neuropathy. We provide the current consensus on prevention and treatment protocols in radiation-induced eye impairments, though most suggested treatment so far should qualify as experimental.

The Role of Decreased Expression of Glucocorticoid Receptors in the Development of Itsenko-Cushing Syndrome
Authors: V. Pechersky. Alexander
Published: June 2024

Background: Itsenko-Cushing syndrome is caused by unregulated excessive cortisol incretion by the adrenal cortex. The causes of increased stimulation of cortisol incretion by the adrenal cortex, leading to hyperplasia and tumors (adenoma and cancer) of the adrenal cortex, as well as to adenoma of the pituitary gland itself, remain unclear to date. Materials and Methods: 6 patients with adrenal Itsenko-Cushing syndrome with adrenal cortex adenoma were under observation. The age of the patients ranged from 24 to 87 years. The patients underwent removal of the adrenal gland on the affected side. The control group consisted of 6 individuals who underwent surgical treatment of varicocele and hernias of various localization. In patients of the main group and control group, with their consent, a small fragment of skin from the edge of the surgical wound was taken for examination, which were fixed in a 10% formalin solution. Results: The presence of adrenal Itsenko-Cushing syndrome in patients of the main group was confirmed by laboratory and instrumental studies, as well as characteristic clinical manifestations. The average Histochemical score of the expression of glucocorticoid receptors (GR) of the skin in patients of the main group with Itsenko-Cushing adrenal syndrome was 2.7 times less than the same value in the control group. Conclusions: A decrease in the formation or absence of glucocorticoid receptors (congenital or acquired) blocks the negative feedback of cortisol suppression of corticoliberin production by the hypothalamus and ACTH-pituitary gland. The resulting excessive incretion of corticoliberin becomes the main link in pathogenesis of pituitary adenoma formation, and an excessive incretion of ACTH leads to the formation of cortical hyperplasia and tumors (adenomas, cancers) of the adrenal cortex. Unregulated excessive cortisol production by hyperplastic adrenal tissues or benign/malignant adrenal tumors leads to overcoming resistance to glucocorticoids and, according to the principle of negative feedback, suppresses the production of corticoliberin by the hypothalamus and ACTH-pituitary gland. As a result, the pituitary form of Itsenko-Cushing syndrome turns into an adrenal form with an unregulated increase in cortisol levels and a decrease in ACTH levels. Transfusion of the mononuclear fraction of peripheral blood obtained from healthy donors, which allows the pluripotent stem cells contained in it to partially replace the altered cells of all tissues of patients, is a promising method of treating patients with Itsenko-Cushing syndrome due to a hereditary decrease in the expression of glucocorticoid receptors.
