Post-Pyrogenic Successions in Oak-Korean Pine Forests with Schisandra chinensis and Corylus mandshurica in Sikhote-Alin
Authors: Prokhorenko N. B. , Komarova T. A. , Glushkoc S. G.
Published: September 2024

This article discusses the results of long-term stationary studies of the formation and development of oak-cedar pine forests with magnolia berry and hazel growing in the Southern and Middle Sikhote-Alin. Considered here are the peculiarities of stands decline, seed-based reforestation, as well as the tree species growth and development courses during the process of reforestation successions in areas with different intensity of fire exposure. Following persistent ground fires, the stands decline is most intensive in the first 5 years, with decay rates and the number of surviving trees varying in different types of burnt areas. The most active seed-based reforestation occurs on post-fire sites mainly during the first 2 years, with birch, aspen and other early stage species predominating. The rate of annual growth of the young generation of trees is the most intensive on plots significantly damaged by fire, in serial species (birch, aspen, Maak’s bird cherry, etc.) they are an order of magnitude higher than in climax broadleaved and coniferous species. Determination of dominance indices, equally dependent on the numbers of undergrowth, thin and large trees, showed that during reforestation successions after both rapid and persistent lowland fires, the phytocenotic importance dynamics in Korean pine, Mongolian oak and other forest forming species has its own peculiarities.
Influence of the Periodicity of Ground Fires in Middle-Аged Pine Forests on the Combustible Materials Stocks
Authors: Sobachkin R. S. , Kovaleva N. M.
Published: September 2024

Significant areas of forest are annually exposed to fires in the Krasnoyarsk Territory. Fires transform forest areas and change the stocks and structure of combustible materials. Information on the dynamics of forest fuel accumulation can serve as a basis for managing the pyrogenic resistance of forest areas. The purpose of the research is to assess the impact of early spring ground fires of different frequencies on the structure and stocks of combustible materials in forests. Experimental fires were carried out in middle-aged mixed-grass-green-moss pine forests in the forest-steppe zone of the Krasnoyarsk Territory. Experimental fires were simulated with different periodicities (annual, with an interval of 2–3 years and a singular one). Regardless of periodicity, the experimental fires led to an increase of combustible materials stocks in 2–3 years after fires. Repeated burnings reduced the stocks of combustible materials close to pre-fire values. The structure of combustible materials has changed, which has led to a decrease in potential flammability of pine forests. The proportion of needles and bark in litter has decreased, and the proportion of cones has increased. Fires led to a redistribution of deadwood classes towards larger diameters. During the research period (2014–2018), the largest reserve of forest fuel loads was noted on the plot with triennial fires (68.2 t ha–1).

B12 deficiency: vital aspects and valid clinical applicability of succinate containing cyanocobalamin
Authors: Evglevsky A. A. , Shuklin S. I.
Published: September 2024

The aim of the research is to review the vital pathological processes in B12 insufficiency and the clinical justification for the use of succinate to potentiate the biological activity of cyanocobalamin. It has been shown that one of the possible reasons for the low clinical efficacy of cyanocobalamin is energy deficiency. The energy deficit is caused by a malfunction of the energy metabolism occurring in conditions of low oxygen supply. In the course of clinical studies, it was found that the double injection of succinate containing cyanocobalamin to cows in the highest possible single doses provided rapid normalization of the reserve alkalinity index and ketone bodies. This effect indicated a qualitative improvement in the processes of energy metabolism occurring in the liver. This was also indicated by a decrease in the physiological values of protein and transamination enzymes AlAT and AsAT. On the contrary, the use of pharmacopoeial cyanocobalamin had no significant effect. Thus, there is every reason to believe that the inclusion of sodium succinate in cyanocobalamin is justified, since it allows to qualitatively improve the biological activity of the drug.

The results of determining the optimal form of thread filling on the technological equipment of the light and textile industry using the computer module of the program for determining the tension of technological processes are given. The computer module of the program for determining the intensity of technological processes, using the recursion algorithm, allows you to determine the optimal form of filling the thread for obstacles in the form of a vertical straight line, a circle and a rectangle. These geometric images reflect real guides and working bodies of technological equipment.
The development of new technological processes in the light and textile industries and the improvement of existing ones is based on the optimization of thread tension in the working area. An increase in the amount of tension leads to thread breaks, and a decrease in its value leads to a violation of technological processes, a deterioration in the quality of manufactured products and, as a result, also leads to breaks in raw materials. Thus, the optimization of the thread tension in the working area allows you to maximally exclude thread breaks, increase the productivity of the technological equipment and the quality of the manufactured products. When processing raw materials on the technological equipment of the light and textile industry, the thread tension gradually increases from the exit zone from the packaging to the working zone. The increase in tension is due to the contact of the thread with the guiding and working bodies of the technological equipment of the light and textile industry. Due to the frictional forces in the contact zone, the thread tension increases after the guiding and working bodies of the technological equipment. The magnitude of the friction force is affected by the angle of coverage of the thread of the guide. The form of filling the thread on the technological equipment is a broken line. The guiding and working bodies of the technological equipment are located at the breaking points. Optimizing the filling form consists in minimizing the total angle of coverage of the guide thread. Graph theory and specialized software must be used to solve the complex task of optimizing the thread filling form on technological equipment.
The magnitude of the frictional force in the zone of contact with the guiding and working bodies of the technological equipment of the light and textile industry depends on the tension of the thread in front of the guide, the radius of curvature of the guide surface, the angle of coverage by the thread of the guide, guide material and thread, speed of thread movement.

The paper presents the results of modeling the process of energy consumption in public, residential, and commercial buildings as a result of the use of various sources of thermal energy. Buildings with such energy sources as: a) a low-temperature gas boiler with a capacity of up to 120 kW for the needs of heat supply of a residential building and freon air conditioning systems for the needs of cooling the building; b) a gas condensing boiler with a thermal capacity of up to 120 kW with a temperature regime of 55/45°C for heat supply and freon air conditioning systems for cooling; c) reversible heat pumping unit of the “ground-water” type with a temperature regime of 35/28°C for the needs of the heating and cooling system and a reversible heat pumping machine with a regime of 55/45°C for the needs of hot water supply; d) a reversible air-to-air heat pump for heating and cooling systems and electric boilers for hot water supply; e) a biomass solid fuel boiler with manual fuel loading with a heat output of more than 100 kW for heat supply and freon systems for cooling; f) a fuel pellet boiler with automatic mechanized fuel loading with a heat output of more than 100 kW for building heating and cooling and freon systems for cooling; g) centralized heating system of the building. The results of calculations of the specific primary energy consumption and specific greenhouse gas emissions for each of the above heat sources are presented. It is established that biomass boilers have the lowest values of primary energy consumption and specific greenhouse gas emissions. The lowest efficiency is achieved by a district heating system with a centralized energy source. The modeling was conducted for the climatic conditions of Vinnytsia. At the same time, the disadvantage of using solid fuel boilers is the limitation of their use in densely populated areas, which is explained by the complexity of flue gas cleaning and regular biomass supply. Therefore, it has been determined that the most efficient source of thermal energy for buildings of various types to achieve the standardized energy efficiency indicators is a ground-to-water heat pump system. This installation, along with providing buildings with thermal energy, allows for cooling in the warm season, operating in reverse mode.

This article explores the application of smart contracts in inheritance matters within the contemporary digital realm. The first part analyzes the complexities and traditional processes of inheritance in Ukraine, identifying various forms of inheritance based on testamentary and intestate succession laws. The subsequent sections highlight the advantages of utilizing smart contracts, emphasizing transparency, automation, and cost-effectiveness in managing inheritance. Additionally, the article discusses legal considerations and underscores the importance of ensuring the reliability of smart contracts. Overall, smart contracts represent an innovative approach to managing inheritance, offering new opportunities for efficient, transparent, and trustworthy asset distribution among heirs in decentralized systems. For the first time, the use of a smart contract in the blockchain was proposed to solve the problem of succession, which opens the way to new opportunities in the field of inheritance and management of inherited assets. They provide transparency, automation, and cost-effectiveness, making them an attractive tool for continuity in decentralized computing systems. Therefore, smart contracts represent an innovative approach to the management of inherited property, which creates new opportunities for efficient, transparent and trustful distribution of property between heirs. In addition, they can ensure the security and inviolability of the rights of the heirs, since all the terms of the inheritance distribution are fixed in the code of the contract, which cannot be changed, which excludes the possibility of its manipulation by any party. Thanks to blockchain technology, smart contracts can also provide security and necessary documentation to enforce inheritance rights to property, while avoiding the shortcomings of traditional inheritance management systems.

The integration of domain-specific knowledge into medical image classification systems presents a promising approach to enhance the accuracy and interpretability of diagnostic models, particularly in the field of medical imaging. This study aimed to evaluate the efficacy of incorporating domain knowledge into multi-strategic classification algorithms for medical images, with a focus on magnetic resonance imaging (MRI) of the brain. This was a comparative, explorative study utilizing a newly developed multi-strategic classification framework that integrates medical domain knowledge into the classification process. The dataset comprised MRI scans of the brain, collected from three different medical institutions, totaling 320 images, which were annotated by expert radiologists. The framework employed basic classifiers, where each classifier was trained on examples incorrectly classified by another, fostering a collaborative learning environment. Performance was compared against traditional single-strategy classification methods. The integrated multi-strategic classification model demonstrated superior performance, achieving higher sensitivity, specificity, and accuracy with 98 %, 97 %, and 96 %, respectively. Furthermore, the model significantly improved the interpretability of diagnostic predictions, aligning closely with expert radiologists' assessments. The incorporation of domain-specific knowledge into the classification of medical images significantly enhances both the accuracy and the interpretability of the results. The multi-strategic approach allows for a more robust and nuanced understanding of complex medical images, such as MRI scans of the brain, potentially leading to improved diagnostic processes and outcomes in clinical settings. Future research should focus on expanding the types of medical images analyzed and further refining the integration techniques to encompass a broader spectrum of domain knowledge.

Покращення функціональних показників машин, механізмів та обладнання, яке набуло значного розповсюдження в сучасному машинобудуванні можливе за рахунок удосконалення операцій фінішної обробки. Одним з головних показників, котрий забезпечить підвищення функціонування гідравлічних машин та паливної системи двигунів внутрішнього згорання є якість виготовлення деталей їх керуючої апаратури. Показниками якості в даному випадку виступають шорсткість поверхні та наявність макронерівностей. Забезпечення обумовлених показників якості в процесі обробки отворів на фінішних етапах залежить від хонінгування отворів. Впливати на отримання обумовлених показників якості можливо за рахунок гнучкості процесу хонінгування отворів.
Гнучкість процесу хонінгування отворів полягає у можливості варіювання показників обробки в залежності від наявних геометричних відхилень. Одним із головних недоліків існуючого процесу хонінгування отворів є конструкція традиційних хонінгувальних головок, які базуються на основі розтискного клину, за рахунок котрого здійснюється регулювання радіального розміру та створення питомого тиску на поверхню, що оброблюється. Також необхідно враховувати той фактор, що процес регулювання радіального розміру відбувається в зоні малих переміщень, що передбачає функціонування обумовленого розтискного клину традиційної хонінгувальної головки в межах переходу від статичного до кінетичного тертя. В статті запропонована конструкція хонінгувальної головки, котра передбачає перехід від тертя ковзання до тертя кочення із забезпеченням умов самогальмування розтискного клину для утворення питомого тиску на поверхню, що оброблюється.
В результаті проведених досліджень наведено порівняння функціонування традиційної хонінгувальної головки та кульково-клинового хону в умовах динаміки. Отримані перехідні та логарифмічно-частотні характеристики свідчать про зменшення впливу дії сил тертя на процес регулювання радіального розміру в процесі обробки. Обумовлені зміни стали можливі за рахунок переходу від тертя ковзання до тертя кочення

У статті описано потенційні проблеми із здоров’ям які можуть виникнути у людей що регулярно використовують засоби віртуальної реальності, а також зведено проблеми які можуть завадити ефективності роботи оператора FPV дрона, який фактивно використовує віртуальну реальність за основу. Описано чинники виникнення проблем зі здоров’ям операторів, а також графік зниження ефективності працівника в залежності від ступеню дизорієнтації оператора дрона. З метою подолання проблем пов’язаних із тривалою роботою у FPV-шоломі під час роботи над задачаю скиду об’єкта з БПЛА запропоновано концепцію «зонінгу скиду БПЛА», що повинна дати можливість оператору БПЛА на перепочинок коли точно відомо що БПЛА може виконати задачу скиду без ризику для оточуючих. Концепція передбачає поділ «мапи» оперативної роботи БПЛА на 3 зони: автоматичного скиду, напівавтоматичного скиду, і також зона заборони скиду. Описано стратегії автоматизованого повернення БПЛА до оператора. Дана концепція спрямована на покращення виконання задачі завдяки більшому залученню ШІ до процесу управління БПЛА, коли оператор не має змоги здійснювати пряме управління, або управління з допомогою ШІ показує більш ефективний результат.

Traditional centralized information protection systems do not provide an adequate level of adaptability and efficiency in a dynamically changing threat environment. Multi-agent systems, having a distributed architecture and the possibility of autonomous decision-making, represent a promising direction for solving information security problems.
The novelty of the research lies in the development of a multi-agent information protection system with enhanced capabilities for vulnerability analysis and intrusion detection. Unlike existing solutions, the proposed system provides active analysis of threats, reduction of the number of false positives, adaptation to new types of attacks, and minimization of the impact on the target traffic of information flows.
In the proposed formal model and prototype of the agent-oriented attack modeling system (ASMA), distributed coordinated attacks on a computer network are considered as a sequence of joint actions of hacker agents, which are performed from different hosts. Hackers are supposed to coordinate their actions according to some common script. At each step of the attack scenario, they try to implement a specific private subgoal.
The developed agent-oriented attack modeling system (ASMA) allows simulating distributed coordinated attacks on computer networks. It is based on a hierarchy of grammars, each of which is interpreted as a finite automaton. The system takes into account both macro- and micro-levels of attack description, providing detailed simulation of each stage of the attack. The use of KQML for communication between agents and XML for describing the content of messages allows effective coordination of agents' actions and ensures realistic simulation of attacks.
VIBRATORY CONVEYOR FOR LOADING FOOD MIXTURE MIXER

The uniform supply of components to the mixing chamber is one of the main keys to the high-quality performance of this technological process. Currently, there is a lack of reliable feeders for mixers of food mixtures, especially of low productivity. This led to conducting analytical studies that make it possible to develop an effective design of the feeder, to determine the rational parameters of its work. As the analysis of the existing designs of feeders for loose materials showed, the problem of providing dosed supply of seeds or other particles in small volumes to the working chamber of the mixer can be solved by using oscillating conveyors, in which the transportation process is carried out due to high-frequency oscillations with a small amplitude. Depending on the operating modes, the material can move in the oscillating conveyor without detachment from the working surface (inertial conveyors) or with detachment (vibratory conveyors). Studies have shown that the most effective in terms of ensuring a stable material supply is the detachable mode of operation of bulk material feeders (vibratory type of feeders). In addition, this mode of operation helps to create a fluidized bed of material, which also increases the reliability of the feeders. The analysis of the movement of the seed along the oscillating plane made it possible to determine the influence of the main factors on the rational parameters that ensure a reliable dosed supply of the seed mass to the mixer of low productivity. The use of the proposed vibrating feeder scheme allows for the required performance, but significantly complicates the design of the food mixer. The conducted analytical and experimental studies made it possible to propose rational constructive and technological parameters of the feeder for the mixer of food mixtures of low productivity. It should be noted that when determining the nature of the movement of the seed mass along the oscillating plane, it is necessary to take into account the effect of the fluidized bed, which is the subject of additional research.
