In the contemporary landscape of scientific inquiry, the study and assessment of risk factors for chronic liver diseases have expanded substantially. This surge in research is driven by the heightened prevalence of common risk factors and the consequential socio-economic impact of chronic liver diseases. Beyond their medical implications, these diseases pose significant economic challenges. Recent scientific investigations affirm that chronic hepatitis (CH) and liver cirrhosis (LC) are predominantly shaped by identifiable risk factors. In this article, synthesizes current research, providing compelling evidence that underscores the societal importance of chronic liver diseases and their association with risk factors. The prevalence of these diseases and their directly linked risk factors is notably high in diverse populations. Moreover, the economic implications of chronic liver diseases extend beyond healthcare, highlighting the need for a multidimensional approach in understanding and addressing these health challenges. As the scientific community unravels the multifaceted nature of chronic liver diseases, this review contributes to the growing body of evidence supporting the assertion that a comprehensive understanding of risk factors is crucial. Furthermore, the abstract advocates for an integrated approach, exploring the intersectionality between risk factors for liver diseases and the critical issue of food safety. By recognizing and addressing this complex interplay, policymakers, healthcare professionals, and researchers can develop targeted interventions that encompass both medical and socio-economic dimensions, fostering a more resilient and healthier society.

Authors: Darian Leonid , Obraztsov Roman , Nikitin Oleg
Published: December 2023

In 2019 a portable diagnostic X-ray system was developed and tested for the inspection of high-voltage equipment (HVE). The system operates based on discrete radiography and is referred by the authors as the first generation X-ray system. As a result of critical analysis of the first generation system, it was further proposed to create a second generation mobile scanning system for HVE digital radiography which is for the first time applied in the power engineering. A physical and mathematical model was developed to establish the relationship between the energy spectrum of the source X-ray radiation and the contribution of this radiation to the image generation during HVE radiography. Using this model, the authors assess the efficiency of the unique X-ray machine used in the first generation X-ray system.

The main technical requirements for the second generation X-ray system, implementing digital scanning radiography, for examining HVE in operation are given.

Authors: Popov Alexander , Butin Kirill , Rodionov Andrey
Published: December 2023

The development of wide area measurement system (WAMS) expands the analysis capabilities of the Unified power system based on computational processing of synchronized phasor measurements (SPM). The analysis of low-frequency oscillations (LFO) in the power system is one of the most relevant applications of WAMS data. The task of locating the source of forced LFO in real-time is highlighted. Due to the increasing complexity and heterogeneity of real power systems, a definitive solution to this problem does not currently exist. However, there are SPM data analysis methods that provide a high probability of identifying the source of oscillations. Informative representation of measurement signals, intermediate, and final LFO analysis results can serve as the basis for decision support tools for operational dispatch personnel. Direct visualization of raw data and computed parameters, such as a set of time function graphs, is inefficient due to the large volume. Therefore, compact high-level representations are in demand. This paper proposes some approaches to visualizing SPM data, computed LFO parameters, and the results of applying various oscillation source detection methods. The presented data visualization methods have been implemented by the authors in a LFO analysis software system.

Authors: Koshelev Valery , Chekmareva Natalia , Romanyuk Maria , Sukharnikova Maria
Published: December 2023

Reindeer husbandry is the main activity of the indigenous peoples of the North, which largely determines the way of life of the local population in the Arctic zone of Russia. For several decades, the industry has been permanently degrading due to technological backwardness. The purpose of the study is to assess the feasibility and effectiveness of transferring reindeer husbandry from traditional grazing technologies to fence keeping technology, as well as organizing the slaughter and processing of reindeer products directly in the places where reindeer are kept. The object of the study was a pilot project implemented by a farmer’s cooperative in the “Omolon Tundra” of the Chukotka Autonomous District. The project consists of several closely interconnected components: the transfer of reindeer husbandry to fence keeping, the introduction of slaughter technologies, primary and deep processing of products. Since the components can be implemented all together within a single project or separately from each other, the study was conducted for three options. Option No. 1 (only switching to fence keeping) does not allow the projected investment and operating costs to be recouped within the project’s estimated period and has an overall negative effect. Option No. 2, which involves not only rearing reindeer, but also primary processing of products, ensures that all costs incurred are covered by the end of the calculation period and even generates a positive net effect. The highest efficiency is achieved when implementing option No. 3, which, in addition to the first two, includes deep processing of reindeer meat. Thus, the effect increases as processing deepens and reindeer herders receive higher added value. The results of the pilot project may become the subject of widespread dissemination in the Arctic zone of Russia.

Published: December 2023

Identification of anthocyanidins was carried out in five samples of anthocyanins obtained under different extraction conditions. It has been shown that anthocyanins are most fully extracted from black currant by an aqueous solution at temperatures of 70°С for 30 minutes and 100°C for 5 minutes, treatment in an ultrasonic bath for 30 minutes and in an ultrasonic homogenizer for 15 minutes. Eight anthocyanidins were identified in the samples of anthocyanins isolated by various methods. The most common were five anthocyanidins - these are cyanidin-3-glucoside, cyanidin-3-rutinoside, delphinidin-3-glucoside, delphinidin-3-rutinoside, petunidine-3-rutinoside. They were identified in all samples of anthocyanins. The proportion of the presence of one or another anthocyanidin in the studied samples depended on the method of isolation of anthocyanins. A more complete release of anthocyanidins is facilitated by the extraction of anthocyanins from blackcurrant berries at temperatures of 70°С for 30 minutes and 100°C for 5 minutes and extraction in an ultrasonic homogenizer at 25°C for 15 minutes. Under these conditions, all eight anthocyanidins are released. Based on this, a technology of the production of anthocyanin dye from berry raw materials was proposed. Developed colorant is a red liquid with a pronounced smell of black currant and a sour taste. Anthocyanin dye has an active acidity (pH) of 3.0, contains 2.99 mg/cm3 of anthocyanins in its composition and has antiradical activity.
The influence of toxic substances in the environment on the activity of antioxidant enzymes in the tissues of Ceratophyllum demersum and Egeria densa
Authors: Makurina Olga , Goryacheva Marina , Lutsay Vladimir , Kropova Yulia
Published: December 2023

In the context of a gradual increase in anthropogenic environmental pollution, detailed environmental studies become relevant. It is very important in this regard to monitor the qualitative and quantitative aspects of the influence of the pollution process on various biological objects that receive the influence of substances entering the environment. Of great practical interest are the toxic effects of technogenic discharges on various hydrobionts and the main mechanisms of their development in macrophyte plants. In this regard, this work studied the influence of heavy metal ions, cationic synthetic surfactants and their combinations on the activity of the main antioxidant enzymes in tissues of Ceratophyllum demersum and Egeria densa. To do this, an experiment was conducted to assess changes in the freshwater macrophytes Ceratophyllum demersum and Egeria densa. The dynamics of the activity of antioxidant enzymes: peroxidase, polyphenol oxidase, ascorbate oxidase and catalase were studied. Their activity was assessed basally and in response to chemical stressors (100 µmol/l lead ions, 1% solution of cationic synthetic surfactants) individually and in combination with different exposures to toxic substances. The identified features of enzymatic activity in the tissues of aquatic macrophytes indicate different levels and power of their antioxidant protection. It becomes clear that the activity of antioxidant enzymes when plants are exposed to certain types of pollutants and their combinations is determined by the chemical nature of the pollutant, the mechanism of its action on the plant organism, the duration of exposure and the localization of these enzymes in cell compartments.

Published: December 2023

The composition and morphology of the n-Al2O3 transition oxide layer at the Al-CdTe interface and the n-MoO3 oxide layer at the CdTe–Mo interface were studied in this work. The Schottky barrier was formed by depositing a polycrystalline p-CdTe layer by a gas-transport reaction in a hydrogen flow onto a Mo substrate. The Schottky barrier was obtained by vacuum deposition of an Al metal layer on the p-CdTe surface. X-ray diffraction phase analysis of the Al–p-CdTe–Mo structure made it possible to establish the real structure, which has the real structure of Al– Al2O3–p-CdTe–MoO3. Based on a scanning electron microscope (SEM), the composition of the Al-p-CdTe structure was studied, where Al is 1.7% Wt, Te is 52.3% Wt, and Cd is 46.0% Wt. The current-voltage characteristics of the Al-CdTe-Mo Schottky barrier in the forward and reverse directions have been studied. The influence of the MoO3 compound layer, which is a wide-gap semiconductor with an n-type orthorhombic structure with a band gap Eg = 2.68 eV, has been revealed. Based on the current-voltage characteristics of the structure, the n-MoO3 layer is determined by smoothing the barrier between the metal and the semiconductor, which affects the mechanism of charge transfer in the structure. The MoO3 compound is a source of electron injection, which is formed during the growth of p-CdTe between the layers of the Mo substrate and the CdTe polycrystalline film. For all samples in the spectral range 190÷900 nm, the absorption edge of Al2O3 films is not observed, which indicates a larger band gap of the oxide Eg ≥ 6.5 eV.

Published: December 2023

The relevance of the research lies in the use of a flexible working body in the form of a cable as part of a soil-cultivating ripping-separating machine. It has been experimentally proven that a flexible working body in the form of a cable as part of an experimental machine provides a more rational redistribution of agronomically valuable soil lumps along the depth of the cultivated layer. When tilling the soil to a depth of 0.03 m, an additional leveling of the soil surface occurs. The combined working body allows for a single pass of the unit to provide high quality tillage and effective control of weed growth. The destruction of dicotyledonous weeds by a machine with an additional flexible working body exceeded the result by 13% obtained without using a flexible working body.

Consumption of plant-derived prebiotics can help reduce the body’s susceptibility to chronic fatigue syndrome, psycho-emotional stress, and the negative effects of increased physical and cognitive overloads. Inulin, a polysaccharide obtained from chicory roots, has beneficial effects on the intestinal microflora. It seems promising to combine inulin with functional ingredients from spinach leaves and quinoa grains. Spinach leaves contain biologically active substances such as carotenoids, phenolic compounds and flavonoids. Quinoa grains contain protein (12.9%), with a high content of lysine and methionine, are rich in fiber, minerals, more than 20 phenolic compounds have been identified in their composition, tannins, saponins, sterols, phytic acid and ecdysteroids are present in small quantities. The aim of this study was to evaluate the effectiveness and safety of the prophylactic administration of the developed complexes to the diet of experimental male Wistar rats. The experiment was carried out during 14 days. Consumption of spinach leaves extract and a complex of spinach extract with inulin by animals decreased the concentration of corticosterone in the blood while simultaneously increasing the content of prostaglandin E2. Consumption of quinoa grain extract and a complex of quinoa extract with inulin significantly reduced only blood corticosterone levels. The beneficial effects of the developed complexes with inulin on the intestinal microbiota have been shown.

In the article we provide examples of the essence of accumulation in the body of gossypol in sheep. The influence due to the accumulation of gossypol in the digestive tract has been revealed. The characteristics of poisoning with meal and husks when feeding sheep are given, and methods for the prevention of diseases caused by gassypol are described. There is still a need to obtain high-quality astrakhan skins, which are obtained after fattening sheep. During fattening, significant mortality is often observed with the diagnosis of gossypol toxicosis and to date, gossypol poisoning has not been fully studied. Purpose of the study: The research was carried out in a special complex for fattening astrakhan sheep and obtaining astrakhan sheep in the Samarkand region of Uzbekistan. To study pathomorphological changes in fattening Karakul sheep with gossypolotoxicosis.

The study showed that fertility at the first artificial insemination (AI) is 9% higher if the voluntary waiting period (VWP) is 80 days compared to 60 days. However, in the second IO, the level of fertilization in both cases remains the same and is 44%.Thus, the period of voluntary waiting for 80 days of milking provides 80% of the pregnant in our herd on the 150th day of milking, which is an excellent indicator.

The purpose of this work was to evaluate the possibility of increasing the CO2 sequestration of hemp in the conditions of urban growth in central Russia by introducing non-traditional fertilizers from agricultural waste. For this, an experiment was carried out on the cultivation of industrial hemp, including the application of fertilizers (biochar, compost, a mixture of biochar and compost). Morphometric indicators, biomass, and chlorophyll content were measured. The absence of a significant effect of fertilizers on morphological (the length of the ground part, the length of the root, biomass) and physiological (chlorophyll content) characteristics was established. Based on the data of the “Register of Green Spaces”, the area of green spaces in Kazan was determined, which can be occupied by hemp (landscaping along roads, sanitary protection zones) – 630.8 hectares. It has been established that it is most expedient to plant hemp using biochar, since this method allows additional carbon sequestration and reduces CO2 emissions from transport by up to 4% per growing season.CO2 is a greenhouse gas with a minimal Global Warming Potential (GWP), however, its contribution to climate change is high due to the large mass of emissions. At the same time, at the moment there are technologies for capturing CO2. However, there is not enough information in the literature about the use of supersequestrator plants such as industrial hemp (Cannabis sativa L., 1753) in large cities to reduce the carbon footprint, and there is practically no data on how sequestration can be increased through the use of various fertilizers, for example biochar.

Sollen Patienten nach gewaltsamen Übergriffen angezeigt werden?
Authors: Menzel Susanne , Brieger Peter
Published: December 2023

Aggressive Handlungen gegenüber Mitpatienten, Mitarbeitenden oder Besuchern durch Patienten sind ein Teil des Alltags akutpsychiatrischer Kliniken; nicht immer lassen sie sich verhindern. In manchen Fällen werden dabei Menschen verletzt, Klinikeinrichtung zerstört. Wie sind solche Ereignisse im Nachhinein zu bewerten? Wie kann eine angemessene Reaktion aussehen? Der Wunsch nach Normalisierung im Umgang mit psychisch kranken Menschen führt auch zur Frage der Eigenverantwortung für Verhalten, durch das Mitmenschen geschädigt oder gefährdet werden. Sollen Menschen, die als Patienten in der Obhut einer Klinik stehen, nach einem solchen Verhalten angezeigt werden? Wodurch ist eine solche Strafanzeige motiviert, wem dient sie, wem kann sie nützen, wem schaden? Der Artikel referiert die Überlegungen und Erwägungen aus einem Workshop zwischen Mitarbeitenden einer Klinik. Erste Anregungen zur Bewusstmachung des Spannungsfelds und zur Erarbeitung von Verhaltensempfehlungen für Kliniken werden formuliert.
