Published: December 2023

A numerical method for determining the settlement and stress-strain state (SSS) of high earth dam of the Charvak hydroelectric power plant is developed based on the finite element method (FEM). The results were compared with the available data from long-term field observations and with records of continuous geodetic monitoring of the dam behavior based on processed space radar images obtained from the Sentinel-1 satellite. To conduct calculations, OJSC Gidroproekt of the Republic of Uzbekistan provided the structural and piecewise non-homogeneous physical and mechanical characteristics of soil of the structure body. The results of calculations of vertical displacements, normal stresses, and pore pressure were compared with field observation data for the section in which the corresponding control and measuring equipment was installed. A cause-and-effect relationship was identified between the water level in the reservoir and the deformation of the dam. The difference between the theoretical results obtained and field observations was up to 10%. A comparison of the results obtained using the finite element analysis calculations (taking into account the level of water filling in the reservoir) with the actually measured deformations of the dam during the filling of the reservoir, and with processed space monitoring data depending on the time of year, showed a good agreement between the measured and calculated displacements.

Published: December 2023

Depending on the development in technology, consumer expectations are also changing. Depending on the changing demands and needs, both the consumers and the virtual environment quickly go to meet these situations. As smart phones make our lives easier, by using mobile internet as a part of the shopping process, the concept of time and space allows the consumer to purchase and access every song, product and service. This mobile shopping is done through mobile applications on phones, thanks to the internet. The brand, which offers great convenience in the decision-making of the consumer in the shopping process, is also perceptually dependent on the consumer's awareness of the brand. The brand, which includes all of the marketing mix activities and makes the business different, shows the power of its awareness as long as it exists in the mind of the consumer. The aim of this study is to examine the effect of consumers using mobile internet on the awareness of a brand. For this purpose, the factors affecting the brand awareness of consumers shopping via mobile internet in Ankara have been comprehensively discussed. The hypotheses created as a result of a comprehensive review of the literature were tried to be examined with the Anova test and regression analysis. The questionnaire form, which was created on the Google form with five-point Likert type scale questions, was applied to consumers who made mobile shopping on the internet. As a result of the analysis of the models, scales and hypotheses used, it was concluded that consumers know their brands and shop according to their awareness.

Using magnetron-ion sputtering, a layer of metallic molybdenum 1–2 μm thick was deposited on the surface of a silicon single crystal grown by the Czochralski method in an atmosphere of an inert argon gas at ambient temperature. According to the results of the experiment, pure Mo layers 2 μm thick deposited by magnetron reactive sputtering from a highly pure metal molybdenum target onto a cold silicon wafer substrate with a thickness of 1.5 mm. They have simultaneously high conductivity and transparency only in the case when a strictly defined deposition rate of molybdenum metal corresponds to a given partial pressure of argon in the volume. The sputtered targets are disks 40 mm in diameter with a thickness of 3-4 mm. The technological cycle of product processing includes the stage of target cleaning. Sputtering of a metal Mo target in pure argon Ar without the addition of oxygen promotes the formation of opaque metal films with very good conductivity. X-ray diffraction analysis of silicon monocrystals with a Mo metal-coated surface revealed compounds Mo3Si and MoSi0.65 in the molybdenum-silicon system. Silicon silicide MoSi2 was found to undergo an allotropic transformation in the temperature range 1850 ÷ 1900 °C, and the low- temperature variety α-MoSi2 has a tetragonal structure. The high- temperature form of β-MoSi2 has a hexagonal structure. The results of the study with an atomic scanning microscope showed that the chains of silicon atoms, connecting with Mo atoms, form zigzags passing through the prisms of the Mo structure along parallel X and Y axes.

Published: December 2023

At present, due to the gradual reduction of glaciation area in high mountainous areas around the world, there is an active transformation of landscapes freed from ice. Namely, the number of glacial moraine-dammed lakes is increasing. Such lakes are often unstable, rapidly changing their morphometric characteristics, which require observation. It is also known that recently there have been more frequent cases of catastrophic outbursts of such lakes and flooding of the territories below. Populations living in such areas are exposed to significant and often uncontrollable risks. One of such lakes, representing a potential threat of breaching, is the Upper Akkol Lake, located on the slope of the South Chuysky Ridge in South-Eastern Altai (Russia, Altai Republic). In this article, we assessed the potential damage from a possible lake outburst, and the information was communicated to local administrations in order to take timely measures to minimize damage or avoid a catastrophe.

There is a need to obtain information on the current state of their properties when reintroducing fallow soils into arable land. The aim of the research was to study fertility indicators of grey forest soils (Luvic Greyzemic Phaeozems) The research area was located in the city of Tara, Omsk region (south of Western Siberia). A field survey of soils and vegetation cover was carried out in plots with different age of fallow land with the establishment of the value of the above ground mass. The results of the research showed that the fallow area with age of less than 10 years is represented by a thick grey forest soil, with age of 10-20 years - by a medium thick grey forest soil. The value of air-dry aboveground mass of plants varied from 1.01 to 1.01 2.58 t/ha. High density, low porosity, and aeration porosity were found in soils throughout the profile. The humus content and reserves in soils are low and average; its distribution in profiles is markedly decreasing. Reaction of soil medium is acidic (рН=4.4-4.8). The sum of exchangeable cations in humus horizons is elevated and high. In composition of cations calcium prevails (71.5-74.9 %) with magnesium share - 22.4-26.9 % and insignificant content of sodium (1.6-2.5 %). The surveyed soils can be reintroduced to arable land. However, it is necessary to provide measures to reduce acidity, improve organic matter balance, reduce density, and increase porosity of upper and subsoil horizons.

Reproduction of soil fertility in adaptive landscape farming systems of the foothill zone of the RNO-Alania
Authors: Mamiev Dmitry
Published: December 2023

Modern intensification of agriculture has significantly speeded up the processes of land destruction and loss of its fertility. This has led to the deterioration in the agroecological situation, boost in the potential fertility of land, and a significant decrease in yields and quality of agricultural products. The purpose of our research was the rational use of land, while compacting the link of the grain crop rotation. The studies were carried out in the foothill zone of the Republic of North Ossetia – Alania, on leached chernozems, in the subzone of sufficient moisture. In the experiments, oats were sown in pure form, mixed with peas, as well as a variant of a pea-oat-sunflower mixture, with harvesting terms for green fodder, grain haylage and grain. Today pea-oat-sunflower mixture, unlike corn for silage, is a resource-saving, low-cost and multicomponent mixture. After harvesting these crops, the crop rotation is compacted by buckwheat crops for grain. With such a sparing use of land resources, the high self-cleaning ability of these mixtures and buckwheat reduces the cost and increases the productivity of arable land. An increase in soil fertility is achieved by introducing green manure crops (winter and spring rapeseed, oilseed radish, white mustard, winter rye, etc.), which, when plowing, improve the soil structure (structural coefficient up to 3), boost the humus content in the soil by 0.02 – 0.05%, neutralize the acidity of the soil environment (up to pH = 5.5 – 6,7), clean the soil from excess nitrates, heavy metals, pesticide residues, etc., and enhance the yield by 15-20%.

Published: December 2023

This research is focused on the development of a recipe composition for meat soufflé enriched with "Iodselen" bioactive additive. The objects of the study were as follows: experimental samples of meat soufflé, obtained according to 3 recipe options with different ratios of the main raw materials, wt.%: quail meat from 80.0 to 90.0, rendered quail fat from 10 to 20. By way of comparison, a meat product has been chosen, the recipe of which is described in patent No. 2726428. As a part of the research, the choice of components of the recipe composition of meat soufflé has been scientifically substantiated, and its quality has been assessed according to organoleptic, physicochemical and microbiological indicators. During the tasting assessment, it has been found that the meat soufflé is characterized by high quality indicators. The highest score has been obtained by sample according to option 3 (5.0 points), in which meat and rendered fat are presented in the following ratio of 85.0:15.0 wt.%. The highest protein content has been measured to be in the meat soufflé according to option 4 which is 28.7%, while the amount of fat in the product obtained according to option 2 was 10.4%, which is 14.7% and 26.6% more than in samples 3 and 4. This is directly related to the introduction of different amounts of basic raw materials into the recipe. It has been found that sample 2 is possessed by the highest energy value of 252.8 kcal (1.058.4 kJ), to the recipe of which 80.0 wt.% of raw meat and 20.0 wt.% of rendered fat were added. However, according to organoleptic assessment, sample 3 is more balanced. The functional orientation of the developed meat product has been proven, so the introduction of 0.06% of “Iodselen” into the soufflé satisfies the body’s daily need for iodine, which is 150 mcg/day, and selenium, which is 55 mcg/day for women and 70 mcg/day for men, for adults (over 18 years old).

Grain production technology in the USSR with minimal use of pesticides
Authors: Mezentsev Sergei
Published: December 2023

The article examines the technological chain of grain production in the USSR with minimal use of pesticides. It was formed and improved throughout the existence of the USSR. Its components were: removal of organic fertilizers to the fields - deep plowing - sowing - treatment of fields and crops with pesticides - harvesting - cleaning and drying - grain storage. The article describes each of these elements in detail, using illustrations for clarity. The article examines the treatment of fields and crops with pesticides as a key element of this chain. If a necessary condition for the implementation of this technological chain was the increase in the number of livestock, as a result of which organic fertilizers were formed in large quantities, then the development of agricultural machinery and the production of pesticides was sufficient. The article emphasizes that the use of pesticides was limited. Many pesticides were banned completely, while others were used in small quantities and within certain periods. The main reasons for such restrictive measures, due to the social system of the USSR, were the production of high-quality bread products for the population and animal feed and the preservation of the environment.

The results of the study are of scientific and practical interest for organizing effective forest management and forest management. Currently, a significant share of clear-cutting occurs in the so-called pioneer development areas (for example, Leshukonsky district of the Arkhangelsk region). In these areas, the approach to forest management must be meaningful and scientifically based in order to prevent deforestation of the areas. Effective use of forests is required by optimizing cutting regimes and parameters, which will allow for intensive forestry with the cultivation of high-quality coniferous wood, ensuring a balance between deforestation and their reproduction with economically valuable species. The goal of the work is to improve the system of forestry activities in the forests of the taiga zone. The basis for the development of assessment indicators for the purpose of felling, their classification in the system of forest use and development, was the scientifically based results of many years of research at stationary objects. For each of the stationary objects, silvicultural requirements and indicators (criteria) were established and developed for the purpose of felling in plantations of different structure, structure, and origin. The status of felling in the classification and in the system of forest use has been established. The results are necessary for the development of forestry development programs in the Russian Federation as part of the implementation of the concept of intensive use and reproduction of forests.

Published: December 2023

The change in capillary moisture capacity of gray forest soil was analyzed at various levels of oil and diesel fuel contamination (50, 150 and 300 ml/kg), as well as as a result of reagent treatment of contaminated soil samples using the nonionic surfactant Tween-80. The concentration of Tween-80 in the wash solutions was 1, 5 and 10 g/L. The ratio of the system components was: 100 g of soil: 400 ml of water: 100 ml of washing solution. Treatment of oil-contaminated soil with washing solutions was carried out for 1 hour with continuous stirring (60 rpm) and a temperature of 20 °C. Contamination of gray forest soils with oil and diesel fuel has led to a decrease in capillary moisture capacity. Thus, the moisture capacity indicator moved from the category “best” (40-50% according to the classification of Kaczynski, 1965) to “satisfactory” (25-30%) or “unsatisfactory” (less than 25%). After washing oil-contaminated soils with surfactant solutions, the values of capillary moisture capacity were restored from the level of “unsatisfactory” to “good” or “best”, although they remained somewhat lower than the level of the parameter of the original (uncontaminated) soil. The results obtained demonstrated an improvement in the studied and so important (in terms of yield) agrophysical parameter of oil-contaminated soil after its treatment with Tween-80. This confirms the prospects of using reagent treatment of oil-contaminated soils using this nonionic surfactant. At the indicated ratio soil: aqueous phase : washing solution, and the contamination level is up to 150 ml/kg (oil) and 300 ml/kg (diesel fuel), the optimal concentration for washing contaminated soil is 5 g/l Tween-80. When reclaiming soils contaminated with oil at a concentration of 300 ml/kg, it is recommended to increase the concentration of surfactants in washing solutions to 10 g/l.

Nanotechnology is one of the emerging areas of scientific interest with numerous applications. In this research, surface modified silicon dioxide nanoparticules have been developed from low molecular weight chitosan by dip-coating technique for the batch treatment of dairy wastewater. The processing parameters of wastewater pH, mixing duration, agitation speed and quantity of nanoparticles are varied, and the treatment efficiency was established by measuring the total dissolved solids (TDS), turbidity, chemical oxygen demand (COD), total suspended solids (TSS), and dissolved oxygen (DO). Dynamic light scattering (DLS), scanning electron microscopy (SEM), energy dispersive X-Ray analysis (EDX), and fourier transform infrared spectrocopy (FTIR) are employed as characterization techniques. The DLS analysis showed the average diameter of the nanoparticles as 320 nm and the EDX analysis confirmed the elemental composition of the silicon dioxide nanoparticles. The functional groups are identified by FTIR. The optimum values for the best treatment conditions are established as pH 3.0, 60 minutes contact time, 100 rpm agitation speed and a nanoparticle dosage of 0.6 g. The batch expérimental study démontrâtes that the surface modified silicon dioxide nanoparticles could efficiently remove the polluants from the dairy wastewater in an environmentally friendly and cost effective method.
Berufliche Sozialisation wider Willen!?

Gewaltanteile psychiatrischer Arbeit sind, gänzlich werteneutral betrachtet, eine Tatsache. Nichtsdestotrotz scheint ein Tabuisierungsprozess eine eingehende Bearbeitung dieser zu verhindern, was verschiedene negative Konsequenzen für alle am Behandlungsprozess beteiligten Personen haben kann. Eine besondere Beachtung sollte dahingehend der Verletzlichkeit und Suggestibilität angehender Fachpersonen geschenkt werden. Eine systematische und frühzeitige Sensibilisierung und Bearbeitung in der schulischen und betrieblichen Ausbildung kann ein wichtiger Beitrag an eine zukünftig möglichst gewaltvermindernde psychiatrische Versorgung, ein positiv konnotiertes berufliches Selbstbild und eine erhöhte Arbeitszufriedenheit von angehenden Fachpersonen sein. Schulungen in Aggressions- und Deeskalationsmanagement könnten hierbei zukünftig eine noch gewichtigere Rolle einnehmen.
Handlungsspielräume, Teamkohärenz und Einstellungen zu prozeduralen Handlungsregeln in psychiatrischen Gefährdungssituationen
Authors: Debus Stephan , Meyer Hendrik
Published: December 2023

Handlungsregeln organisieren und synchronisieren die Abläufe aller Situationen in psychiatrischen Akutstationen. Das Forschungsprojekt „Simulation und Reduktion von Zwangsmaßnahmen in der Psychiatrie“ (SRZP) fokussiert sich auf die Analyse von psychiatrischen Gefährdungssituationen (PGS), d. h. auf jene wenigen Minuten, bevor und während Zwangsmaßnahmen angewendet werden. Die vorgestellte Methode der konstitutiven und regulativen Regeln vollzieht einen Perspektivwechsel von der personenzentrierten zur situationsbezogenen Analyse der Gewalt- und Zwangsvorkommnisse. Durch eine Informantenbefragung zur Einstellung (Zustimmung, Ablehnung) und zum Realitätsstatus (Geltung, keine Geltung) der Regeln wird gezeigt, wie verschiedene Handlungsspielräume (Orientierungsraum, Obligationsraum, Alternativraum und Ausschlussraum) in der Behandlungspraxis voneinander abgegrenzt werden können. Im Ergebnis dieser Studie: von allen interklinisch in PGS identifizierten Handlungsregeln (ni = 918) zeigen sich intraklinisch 61,4 % als gültig, aber 71,8 % finden Zustimmung. Die Diskrepanz wird durch ein ungeregeltes Entscheidungsvakuum erklärt, das die Teamkohärenz bedrohen könnte, wenn im Team die Einstellung vorherrscht, dass dieses Vakuum besser geregelt werden sollte. Die Studienlage, die einen gegenläufigen Zusammenhang zwischen steigender Teamkohärenz und Gewaltreduktion herstellt, bestätigt die vorgestellten Ergebnisse. Eine Anwendung der Ergebnisse besteht darin, die Diskrepanz gezielt für Deeskalationstraining und Teamsupervision zu nutzen, um den Reformstau in Richtung einer gewaltärmeren Psychiatrie abzubauen.

Published: December 2023

Objective:

Yixishu lotion (YXSL) originates from the summary of traditional Chinese medicine clinical experience and constantly improves in practice in clinical validation of the exact efficacy of traditional Chinese medicine prescription. To explore the mechanism of YXSL in treating vaginitis and the potential mechanisms based on network pharmacology and experimental verification.

Methods:

The active components and drug-related targets of YXSL were retrieved from the TCMSP (Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform) database, and the target was predicted by the UniProt database. Searching for genes related to ‘vaginitis’ disease in the GeneCards database, a total of 2581 drug targets were obtained. The interaction between proteins (PPI – protein–protein interaction) relationship was obtained by STRING database and visualized by Cytoscape software. Finally, the ‘Bioconductor’ installation package in R software was used to analyze the GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways of the target.

Results:

In this study, by the method of network pharmacology, the key active components of YXSL were flavonoids such as quercetin, apigenin, kaempferol, luteolin, β-sitosterol; the main core proteins included MAPK14, TP53, FGF2, ESR1, MAPK3, MAPK1, VEGFA, JUN, IL-6, and the KEGG pathway was mainly involved in MAPK pathway, Th17 pathway, Malaria, TNF pathway, and other signaling pathways. Animal experiments showed that the clinical symptoms and vaginal tissue lesions of the YXSL group and the fluconazole group were improved, and the levels of TNF-α (tumor necrosis factor alpha), IL-6 (interleukin-6), MDA (malondialdehyde), SOD (superoxide dismutase), IL-4, and IFN-γ (interferon-γ) in vaginal tissue and serum were better than the model group.

Conclusion:

YXSL may achieve its therapeutic effect on vaginitis by reducing the inflammatory response, improving oxidative stress response, and improving body immunity, and it provides a theoretical basis for further research on its pharmacodynamic material basis and mechanism of action.
Facilitating conditions and institutional repository sustainability by librarians in public university libraries in Nigeria
Authors: Esse Ugwunwa , Haliso Yacob-
Published: December 2023

Purpose

This study aims to investigate the facilitating conditions (FCs) and how these FC affect institutional repository (IR) sustainability practices in public universities in Nigeria.

Design/methodology/approach

A survey research design was adopted in this study. The study population comprised 542 librarians from public universities that have IRs across Nigeria. A sample size of 230 librarians was determined using Taro Yamane’s formula. A multi-stage sampling technique was used to select the respondents in three stages, which were purposive, stratified and purposive sampling. A structured, validated questionnaire was used for data collection. Data were analyzed using descriptive and inferential (simple and multiple regression) statistics at a 5% level of significance.

Findings

The result revealed that the availability of FCs (ßeta = 0.459, t(211) = 7.719, p = 0.000) has a positive and significant influence on IR sustainability in public university libraries in Nigeria. The F-test (1, 223) value of 59.582 shows that there is sufficient evidence to substantiate the model’s usefulness in explaining IR sustainability. The R2 (0.211) indicates that 21.1% of the variation in IR sustainability is explained by the availability of FCs in public university libraries in Nigeria. The finding suggests that the availability of FCs is a vital predictor of IR sustainability in public university libraries in Nigeria. The result also depicts that out of the eight parameters that measure the availability of FCs, it was current awareness of IR that had a positive and significant influence on IR sustainability.

Originality/value

This study concluded that ICT skills and FCs are contributory factors to IR sustainability practices by librarians in public university libraries in Nigeria. It was recommended that university administrators formulate policies that promote the sustainability of IR and provide adequate funds to support IR sustainability. Furthermore, the library management in public university libraries in Nigeria should drive content recruitment and create awareness of the IRs among students and faculty to ensure continued use.
Shariah-compliant firms and earnings management: do continuation and ethnicity matter?
Authors: Khaw Karren Lee-Hwei , Al-Jaifi Hamdan Amer Ali , Zainudin Rozaimah
Published: December 2023

Purpose

This study aims to revisit the relationship between Shariah-compliant firms and earnings management. Specifically, the authors examine whether Shariah-certified firms have lower earnings management than non-Shariah-certified firms and how often a firm must hold its certification to observe considerably reduced earnings management. This study also explores how senior management ethnic dualism affects the association of Shariah certification and earnings management.

Design/methodology/approach

The authors analyze the hypothesized association between Shariah certification and earnings management using a panel regression model and several robustness tests, including the Heckman selection model. The sample consists of 547 nonfinancial firms listed on the Bursa Malaysia stock exchange, with 5,478 firm-year observations over the 2001–2016 sample period.

Findings

Shariah certification is found to mitigate earnings management, particularly for firms that consistently retain their Shariah status. The longer firms retain their Shariah certification continually, the lower the earnings management. Additionally, the results indicate that the negative impact of Shariah certification on earnings management is driven by ethnic duality when a specific ethnic group dominates the top management.

Research limitations/implications

Firms’ commitment to religious-based screening and continuation of certification plays a significant role in improving earnings quality. Firms are committed to abiding by the Shariah code of conduct instead of using the Shariah status for reputation purposes to attract investors.

Practical implications

For investors, the continuous compliance status is a crucial indicator of a firm’s commitment to comply with Shariah principles and to mitigate earnings management. Regarding policy implications, Shariah-compliance guidelines can constrain earnings manipulation, especially among firms lacking ethnic diversity.

Originality/value

The study shows that Shariah certification must be maintained consecutively to reduce earnings management. Shariah certification’s governance function is crucial in ethnically homogeneous firms, primarily when one ethnic group dominates the senior management.
