Authors: Khairnasova Alina
Published: October 2024

ulcerative colitis is a complex disease that results from a complex interaction of genetic predisposition, environmental factors, which leads to dysregulation of the immune system, chronic intestinal inflammation with damage to the mucous membrane. Systemic chronic inflammation can cause the development of arterial hypertension, thereby complicating the course of the primary disease. However, the cause-and-effect relationship between these diseases is not fully understood. Early detection of high blood pressure in patients with ulcerative colitis, a multidisciplinary approach to diagnosis makes it possible to achieve optimal treatment results in a timely manner and prevent the occurrence of intestinal complications. The aim of this study was to provide a comprehensive review of diagnostic procedures such as colonoscopy, inflammatory biomarkers (faecal calprotectin, faecal lactoferrin, serum zonulin), and to study the features of the colon structure in ultrasound diagnostics in patients with ulcerative colitis and concomitant hypertension. The data from PubMed and Ukrainian scientific sources on the comorbidity of these diseases, the possibility of using non-invasive diagnostic methods to assess the condition of the intestine in patients with ulcerative colitis and arterial hypertension were analysed. The literature review includes 50 scientific sources. The main focus is on the pathophysiological relationships of diseases, peculiarities of non-invasive diagnosis of ulcerative colitis during follow-up and early detection of arterial hypertension, which makes it possible to prevent complications in ulcerative colitis. Given the literature review, it can be concluded that the problem of timely diagnosis of hypertension in patients with ulcerative colitis is relevant today. For a rational approach to the management of patients with ulcerative colitis and concomitant hypertension, it is necessary to carry out a set of diagnostic procedures, including outpatient blood pressure measurement, ultrasound examination of the intestinal wall, and the use of non-invasive inflammatory biomarkers.

Long-term liver deportalisation in stable and time prolonged prehepatic portal hypertension model affects expression of hypoxia, angiogenesis, apoptosis, and autophagy markers in the young rats’ liver
Authors: Godik Oleg
Published: October 2024

prehepatic portal hypertension in children cause severe and life-threatening complications, that highlights the need in in-depth investigations of pathogenetic mechanisms, which contribute to prehepatic portal hypertension-associated liver pathology. In developed stable experimental prehepatic portal hypertension model in adolescent rat males we aimed to assess the expression levels of the key molecular markers of hypoxia, angiogenesis, autophagy, and apoptosis in the liver tissue after 6-month deportalization. Partial portal vein ligation was performed in 4-week old male rats. After 6-months tissue samples from PHP-model, sham operated and control animals were studied by western blot to identify protein levels of markers related to prehepatic portal hypertension -induced liver injury. Partial portal vein occlusion upregulated hypoxia inducible factor -1α (by 4.67 folds vs. control, p<0.001) and vascular endothelial growth factor protein expression levels (by 2.33 folds vs. control, p<0.001) suggesting chronic hypoxia development. Abnormally high levels of angiostatin isoforms were found (by 9.88 folds vs. control, p<0.001) to signify angiogenesis dysregulation. Significant caspase-3 (23.4-fold increase vs. control, p<0.001) overexpression is executive phase of apoptotic cell death evidence. Dramatic LC3 level expression indicates existence of crosstalk between autophagy and apoptosis that contribute to fibrotic changes. Hypoxia-induced events, impaired angiogenesis regulation, enhanced autophagy and apoptosis are contributing factors of prehepatic portal hypertension -induced liver injury. A better understanding of subtle molecular mechanisms of this pathology may pave the way for innovative treatment options.
Breaking the Illusion (破相) of Local Realism: Bridging Classical and Quantum Physics Through the Lens of Buddhist Doctrine
Authors: Leong David
Published: October 2024

This paper examines the concept of 破相 (_pòxiàng_), which in Buddhist philosophy refers to the deconstruction of appearances or forms, and this paper uses it as a theoretical framework to bridge the gap between classical and quantum physics. Classical physics presents a deterministic, well-defined reality where objects exist with fixed properties independent of observation. However, quantum mechanics challenges this view, revealing a probabilistic, fluid, and deeply interconnected reality with the observer’s perspective. The Buddhist doctrine of _pòxiàng_, which involves recognizing the illusory nature of fixed forms and appearances, provides a powerful philosophical lens through which the principles of quantum physics—such as superposition, entanglement, and the observer effect—can be interpreted.

By examining the groundbreaking work of physicists John Clauser, Alain Aspect, and Anton Zeilinger, who shared the 2022 Nobel Prize in Physics, this analysis demonstrates how their experimental confirmations of quantum entanglement and violations of Bell inequalities not only challenge classical notions of locality and determinism but also resonate deeply with Buddhist metaphysical insights. This interdisciplinary study argues that Buddhist ideas about illusions and the impermanence of forms correspond to the quantum state’s inherent uncertainty and non-fixed nature. This paper suggests a deeper, more integrated understanding of reality by exploring how classical physics’ rigid view of reality is ‘deconstructed’ at the quantum level, similar to the Buddhist recognition of form as an illusion. The research contributes to scientific and philosophical discourses by highlighting how the impermanence and illusion of fixed forms in Buddhist doctrine can be seen as metaphors for the collapse of the quantum wave function into a definite state upon observation.
Organised Crime from the Middle East and the Czech Republic
Authors: Nožina Miroslav
Published: October 2024

Organised crime (OC) from the Middle East, sometimes called 'Arab Organised Crime', does not attract as much attention as Chinese, Italian or Russian OC. However, especially in the context of illegal migration, illegal trade in drugs and terrorism, it is going to be a very significant security issue. The Czech Republic has become one of the crossroads of Arab organised crime in Europe. Many ethnic Arabs permanently lived in the former Czechoslovakia before 1989 because of the former communist regime's good relations with the Arab countries. Some of these persons holding Czech citizenships created cells of Arab OC groups which have penetrated the CR since the beginning of the 1990s. The Arabs are engaged in marijuana and hashish smuggling from Northern Africa and Central Asia-and in the last 2 to 3 years in the heroin trade as well. They are active in the weapons trade, illegal migration and financial fraud. The Czech Arab underworld has contacts with fundamentalist and terrorist organisations such as the Algerian FIS, GIA, Palestinian Liberation Front, Hezbollah and Al Fatah. Increasing activity was registered in connection with the start of Radio Free Europe's broadcast from the CR to Iran and Iraq. The article defines the role of the CR in the Arab international criminal networks, estimates future trends in the development of the Czech criminal underworld and the impact of the Arab OC activities on the Czech economy and society.

Для защиты материалов от абразивной коррозии можно использовать различные методы термического напыления для нанесения покрытий, такие как порошковое напыление газовым пламенем, плазменное напыление, напыление и плавление, высокоскоростное кислородно-газовое напыление и детонационное напыление. Термическое напыление является одним из наиболее эффективных методов защиты материала от износа и коррозии, тем самым увеличивая срок службы материала. В данной статье представлено изменение поверхности покрытий на основе Ni-Cr-Al методом импульсной плазменной обработки с использованием плазменного генератора. Покрытия были получены методом детонационного напыления (DS), после чего прошли импульсную плазменную обработку (PPT). Изучены изменения структурно-фазового состояния покрытий под воздействием плазменного потока. В работе использовались сканирующая электронная микроскопия (SEM), рентгеновская энергодисперсионная спектроскопия (EDX), рентгеноструктурный анализ (XRD), характеристика шероховатости поверхности, испытания на твердость и трибологические испытания для комплексного анализа изменений характеристик детонационных Ni-Cr-Al покрытий. Показано, что модификация поверхности покрытий импульсной плазменной обработкой приводит к увеличению износостойкости их поверхностного слоя за счет уменьшение коэффициента трения и увеличение микротвердости. Согласно результатам рентгеновского фазового анализа, улучшение трибомеханических свойств полученных поверхностей связано с увеличением содержания фаз CrNi3, NiAl и NiCr в обработанных покрытиях.

Authors:   Joldasbekov, Institute of Mechanics and Engineering, Jomartov A.A.
Published: October 2024

A prototype of a suspended point cable parallel robot with a control interface and three translational degrees of freedom was designed and manufactured. The prototype of a point cable parallel robot consists of a metal frame in the shape of a rectangular parallelepiped; winches with servo motors are located near the base of each vertical post, designed for winding (or winding) cables. The other ends of the cables passing through the pulleys are connected to the working body. The direction of rotation, as well as the rotation speed of winches with servomotors, are set by a control unit that has three translational degrees of freedom. Four force sensors were used to determine the tension in the cables of the suspended point cable parallel robot. The force sensors are connected to the ZET 058 strain gauge measuring system, which, together with the ZETLAB TENZO software, allows you to collect information in real time through four channels simultaneously. Experimental studies of a prototype of a suspended point-cable parallel robot were carried out by drawing a circle trajectory with an end-effector. It has been established that the deviation of the trajectory from an ideal circle occurs as a result of tension fluctuations in the cables. Experimental graphs of the tension in the cables were obtained using force sensors connected to the ZET 058 strain gauge measuring system. It was established that in order to increase the accuracy of the operation of the suspended point cable parallel robot, constant monitoring of the tension of its cables is necessary.

The article is devoted to the development of a device for the production of pressed granules. Granular feed is considered as a promising product for animal husbandry due to their high nutritional value. The description of the feed granulator as the basis for the production of pellets from fodder crops is given. One of the key elements of the granulator is a matrix, which is a steel part with many holes through which the nutrient mass is passed under pressure during granulation. The matrices are divided into planar and annular. Granulators by design are also divided into roller, drum, disc, blade, vibrating and rotary-centrifugal. Granulators can also be domestic and industrial, which differ from each other in different overall dimensions and performance. To date, the production of granulators is carried out at some plants in Russia. Based on the message of the President of the Republic of Kazakhstan, it follows that Kazakhstan needs to establish its own production of equipment for processing raw materials of the agro-industrial complex, including feed pellets. In the course of our research, we have developed a feed granulator. The design of the developed granulator will reduce peak loads on the working bodies, increase reliability, and improve the feed mixture supply to the area of operation of the working bodies. The granulator consists of a base (housing), shafts, an unloading blade, a die, a washer, a screw with an internal hexagon, a spring lock washer, a nut, a screw with an internal hexagon, bearings, a lock washer, a prismatic key, a ring, a screw, a roller and a distribution blade. The developed feed granulator has a simple design and compact appearance. Its design will allow the production of granular feed of good quality and optimal consistency.

The paper presents the findings of a study investigating the properties of sprayed coatings with subsequent electrothermally treated within the context of the Ministry of Internal Affairs of the Republic of Kazakhstan grant project AR19680421. This study considers the peculiarities of electric current flow through the sprayed coating or pre-formed powder layer. The properties of 40X13 steel coatings obtained by hypersonic metallization followed by electrothermosilic treatment are investigated. A method for obtaining a wear-resistant coating is proposed, including the formation of a jet of sprayed particles of two metal wires melted in an electric arc, their deposition as a layer on a pre-prepared surface of the part and subsequent electrothermosilic treatment of the layer. It is proposed to choose martensitic steel as the material of one wire, nickel–chromium or iron-chromium alloy with high electrical resistivity as the material of the other, and the diameter of the wire made of this alloy should be determined depending on the diameter of the steel wire.

Currently, maintaining agricultural machinery in a constant working condition is an urgent task. Studies carried out to study the state of the problem in the conditions of agricultural enterprises of the Republic of Kazakhstan have shown that the lack of centralized repair and restoration bases and production facilities has a negative impact on the quality organization of agricultural machinery. Because of this, it is impossible to carry out repair and restoration work in a timely and high-quality manner, as well as technical maintenance of agricultural machinery and equipment. To solve this problem, it is proposed to use АM technologies in the repair and manufacture of parts of agricultural machinery and machines. To this end, the existing methods of additive technology were investigated. An experimental study was conducted on the manufacture of a «shaft-gear» part using a Stratasys F170 3D printer in the laboratory of the Department of «Technological Machines and Equipment» of the Kazakh Agrotechnical Research University named after S. Seifullin. The results showed that the time of 3D printing directly depends not only on the size of the model, but also on the density and shape of the filling, as well as on the thickness of the printing layer. It was found that an increase in the thickness of the layer has a twofold effect on the 3D printing process - it has a positive effect on reducing the printing time, but it has a negative effect on the rigidity of the printed sample.

In the 21st century, the concept of sustainable development has become a key foundation for humanity's future growth. The sustainability strategy is now broadly understood and influences all aspects of life, including education. Global threats to civilization, including economic, demographic, military-political, environmental, and socio-cultural processes, present significant challenges in socialization and adaptation for the younger generation. It is no longer possible to address these issues without the comprehensive and extensive use of preventive development mechanisms. Undoubtedly, one such crucial mechanism is the sphere of education, particularly the architecture of schools. Therefore, architecture, as a key resource in education, must evolve to a new level. The research's relevance lies in the need to apply new architectural and urban planning principles in designing modern schools that ensure an ecologically comfortable and sustainable educational environment. The study analyzes the creation of sustainable school architecture, using the Bali Green School in Indonesia as a positive example of successful implementation. To thoroughly explore the research topic, the authors utilize insights from natural, human, and social sciences, including ecology, psychology, philosophy, pedagogy, and microbiology. The study identifies five key principles: integrating architecture with nature, architectural identity, permaculture, openness in educational spaces, and environmental well-being.
The effect of the track plan on the damage to rails by contact fatigue crambling

Published: October 2024

An analysis of foreign and domestic experience in improving traffic safety while extending the service life of rails and improving their interaction with the wheels of rolling stock shows that the working conditions of rails are much more difficult in curved sections of the track, especially in the outer thread, due to the intense impact of the ridges of the wheels of rolling stock on the lateral working One of the reasons for the formation of contact fatigue stains on the lateral working surface of the rail head is the presence of tangential stresses that occur in the absence of perpendicular pressure of the wheel on the rail head. In addition, the movement of the wheels on the rails is accompanied by slippage, which appears due to the taper of the wheels and the occurrence of the wheel crest on the rail head. A typical case of the wheel crest running over the rail head is the movement of the crew along curved sections of the track. In this case, the guide axle runs over one of the wheels on the rail head. As a result, there is a transverse slip of the wheel on the rolling surface and friction forces between the wheel and the rail are appropriately oriented to the axes. These processes, enhanced by an increase in dynamic action, cause more intense damage to the rail heads by defects 11 in the curves, while defects mostly appear on the outer rail thread.
Explosive Ordnance Detection in Areas Designated for Mining

Nowadays, mining is becoming increasingly valued, as mines of various types provide a large part of the raw materials needed for construction. In order to ensure a continuous supply of extraction and raw materials, new areas need to be identified and opened up. However, some of these new areas may contain security risks such as explosive remnants of war. If we look back to the events of the World War II, there was perhaps no area in Europe that was not affected by the preparation or execution of some act of war. The warring parties deployed a full arsenal of weapons, some of which still pose a threat today. The various types of bombs, mines, projectiles and grenades were only partially operational. Explosive devices that were simply left behind or unexploded were buried beneath the surface, and continue to pose a growing threat to this day (almost eight decades later). The dismantling and disposal of the left-behind and often very poorly recovered explosive devices has been ongoing ever since. The problems of finding explosive devices and munitions tend to occur in areas where there has been no previous investment, construction or earthworks.
