Authors: Hassan Naser Abed , Ahmed Hassan Ali , Mohammed Akram Khalaf 
Published: January 2024

Large areas of soil in Iraq are formed up of gypsum soil. As a result, understanding the habits of this soil and its treatment approach is critical, because its current solution is to replace gypsum soil before beginning any building activity. This study used gypsum soil from Tikrit City, which has a gypsum concentration that is around 38%, and the goal of the study is to illustrate the impact of the polymer on the gypsum soil parameters. Simultaneously, researchers are investigating the beneficial effects of polymers on the behavior of gypsum soil. The percentages of the polymer additive (5%, 7.5%, 10%, 12.5%, and 15%) were weight percentages, while the soil tests were chemical, physical, and engineering. When the percentage of additive was increased from 0% to 15%, Soil engineering characteristics enhanced the collapse of the from 5.11 to 1.21, cohesion improved from (28.98 KN/m2) to (51.16 KN/m2), and angles of internal friction decreased from 33.190 to 38.850.

Published: January 2024

Purpose: Compare certain steps of strawberry jam processing, energy consumption, waste generation, as well as indicators of jam quality obtained through industrial and homemade methods.

Method/design/approach: The jams were prepared in the fruit and vegetable laboratory as well as in the pilot plant. The bottling process involved hot sealing in glass jars with metal lids. After sealing, the jars were inverted, cooled, and stored at -18 °C until analysis. The ingredients used included high methoxyl pectin, citric acid, sucrose, and fresh acidic lemon juice. The analysis included the use of various chemicals such as methanol, sodium acetate, potassium chloride, hydrochloric acid, NaOH, ascorbic acid, dihydrated oxalic acid, and 2,6-dichloroindophenol.

Results and conclusion: The study examined industrial, semi-industrial, and homemade jams, highlighting changes in color parameters and losses of anthocyanins and ascorbic acid over time. Homemade jams exhibited greater variations in both color and processing. Strawberry pre-processing and water consumption differed between industrial and homemade productions, with a higher disposal rate observed in industrial production. The yield of industrial jams remained consistently above 90%, whereas homemade jams showed variations. Energy consumption was higher in homemade jams, making the industrial process more energy-efficient. Industrial vacuum processing provided advantages such as lower temperatures, reduced sensible heat, and minimized chemical changes, but it necessitated more expensive and maintenance-intensive equipment.

Originality/value: In contemporary discourse, there has been substantial censure directed towards industrialized foods in recent years, with a considerable portion lacking a rigorous scientific foundation. This study contributes by presenting findings that facilitate the discernment of advantages stemming from both industrial and artisanal processes, contingent upon the availability of requisite technical knowledge.

Published: January 2024

Na região semiárida do nordeste brasileiro ocorre a extração ilegal da biomassa florestal. A Paraíba tem um grande potencial, sua vegetação e recursos madeireiros desenvolve um importante papel na economia regional, com a produção de lenha e carvão, além da produção animal. Embora esses aspectos sejam importantes para a economia, promovem a supressão da cobertura vegetal, e de forma associada com a intensificação dos fatores climáticos tem proporcionado grandes mudanças no semiárido paraibano, a exemplo do que ocorre no município de Cabaceiras. Nesse sentido, o objetivo deste estudo foi realizar uma análise da cobertura vegetal com um recorte do município de Cabaceiras, para identificar a situação atual e as mudanças ocorridas no período de 2009 a 2019, utilizando diferentes índices de vegetação. Para a realização do trabalho, foram adquiridas imagens da série LANDSAT para os anos de 2009 e 2019, disponibilizadas gratuitamente pelo UnitedStates Geological Survey (USGS). O software utilizado para o processamento das imagens foi o QGIS, versão 3.4.13. Com relação aos índices, foram selecionados os demais larga aplicabilidade, incluindo o Índice de Vegetação da Razão Simples (SRI), o Índice de Vegetação da Diferença Normalizada (NDVI), e o Índice de Vegetação Ajustado para o Solo (SAVI). Os resultados evidenciam a eficiência do uso do sensoriamento remoto para análise da cobertura vegetal. É possível verificar que existe regeneração em alguns pontos, porém também mostra uma grande transformação de áreas de vegetação, levando ao aumento de vegetações de baixa densidade em detrimento das de alta e média densidade no período de 2009 a 2019, com destaque especial para a região central do município de Cabaceiras. Esse resultado sugere que os órgãos ambientais por mais que estejam atentos para executar algum tipo de controle sobre a supressão da vegetação de caatinga, ainda assim é uma ação insuficiente, visto que se verificou em boa parte do município a diminuição da cobertura vegetal. Isso sugere a atenção tem sido dada para áreas específicas e a exploração da caatinga tem ocorrido em todo o município, aumentando a fragmentação florestal. Esse resultado é um alerta para a dificuldade de fiscalização, quando a exploração é realizada em pequenas áreas de forma difusa e sem planejamento em todo o município.
Analytical calculations of fifth-order electromagnetic corrections to the anomalous magnetic moment of leptons within the Mellin-Barnes representation
Authors: Solovtsova O. P. , Lashkevich V. I. , Kaptari L. P 
Published: January 2024

We investigate the explicit, analytical expressions for the fifth-order electromagnetic corrections in the fine structure constant α to the anomalous magnetic moment of leptons aL (L = e, μ, τ) from diagrams with insertions of the vacuum polarization operator consisting of pure lepton loops. Our approach is based on the consecutive application of dispersion relations for the polarization operator and the Mellin – Barnes transform for the propagators of massive particles. Exact analytical expressions for the corrections to aL from vacuum polarization by four identical loops are obtained. Asymptotic expansions are found in the limit of both small and large values of the lepton mass ratio (r = mℓ /mL), r≪ 1 and r→∞ The resulting expansions are compared with the corresponding expressions given in the literature.
Unconditionally monotone and globally stable difference schemes for the Fisher equation
Authors: Matus P. P. , Pylak D. 
Published: January 2024

In this paper, we construct and study unconditionally monotone and globally stable difference schemes for the Fisher equation. It has been shown that constructed schemes inherit the stability property of the exact solution: 0 ≤ u(x, t) ≤ 1, (x, t) ∈ QT = {(x, t) : 0 ≤ x ≤ l, 0 ≤ t < +∞} for a given input data of the problem. The unconditional monotonicity of the difference schemes is proved and the a priori estimate is obtained in the uniform norm for the difference solution. The stable behavior of the difference solution in the nonlinear case takes place under slightly more stringent constraints on the input data: 0,5 ≤ u0 (x), µ1(t), µ2(t) ≤ 1.
The scientific recommendations on the organization of state intervention regulation in the agricultural sector at the present stage
Authors: Panasyuga N. P. 
Published: January 2024

State intervention regulation is a variable system, the effectiveness of which depends on the priorities of the state’s active intervention in the functioning of the market, in conjugation of the interests of market counterparties. They, in turn, follow from the current situation and strategic development objectives. When preparing the article, we proceeded from the fact that it is practically impossible to develop a universal scheme of intervention impact. This conclusion is confirmed, among other things, by studying the scientific literature – the recommendations of the authors have many distinctive features both in terms of the range of issues under consideration (commodity and price interventions, correction of export-import operations, state support, stimulation of scientific and technological progress, etc.), and specific conclusions attached to them. It is necessary to take into account many factors, the role of each of which individually is different in its significance, direction, strength and duration of impact, and in the aggregate forms unique combinations, the nature of the influence of which is very diverse.In this regard, the paper gives recommendations in relation to the current situation, which takes into account integration processes, resource opportunities, and the potential for growth in demand for food on the world market. We took into account the developments of both Belarusian and foreign scientists, taking into account changes in the demographic situation, the unfavorable political background of trade with unfriendly countries, their results are critically rethought, on the basis of this, a complete author’s system of recommendations on key areas of state economic interventions in the agroindustrial complex is presented.

In the context of the COVID-19 pandemic, medical workers (MW) turned out to be the most vulnerable category of the population at risk of developing psychoemotional disorders.
The study aims to establish the characteristics of the state of the psychoemotional sphere in doctors of surgical specialties of COVID-hospitals, multidisciplinary hospitals (MDH) during the COVID-19 pandemic, as well as outpatient clinics (OPC).
We have examined the following groups of doctors: group 1 consisted of doctors of surgical specialties working in COVID‑hospital (n=61); group 2 consisted of doctors of surgical specialties working in a multidisciplinary hospital (n=58); group 3 consisted of doctors of surgical specialties working in the outpatient clinic (n=55); group 4 — the control group included employees of engineering, technical and economic specialties not related to work in medical organizations (n=190). The authors have evaluated the professional burnout syndrome using a questionnaire on the assessment of professional burnout "Maslach Burnout".
The work of doctors of surgical specialties during the COVID-19 pandemic is associated with the impact on medical workers of a number of specific risk factors associated with the provision of medical care to infected patients, as well as with significant changes in work, regarding aspects related to organization, safety, which contribute to increased levels of anxiety, professional burnout, stress.
The work of doctors of surgical specialties during the pandemic of the new coronavirus infection COVID-19, compared with doctors of multidisciplinary hospitals and outpatient doctors, is associated with an increase in the level of occupational stress, the level of professional burnout. It is necessary to continue research on the emotional state of medical personnel in order to timely carry out preventive treatment to preserve the health of medical workers.

Published: January 2024

Introduction. The annual increase in air temperature is one of the reasons for the occurrence of large-scale destructive fires throughout the world. The consequences of the negative impact of air pollution during forest fires on the respiratory and cardiovascular systems have been widely and well studied. At the same time, insufficient attention is paid to the influence of forest fire smoke on the functioning of the central nervous system.
The study aims to study the morphofunctional state of the central nervous system of white male rats under prolonged exposure to forest fire smoke.
Materials and methods. The study was conducted on 60 outbred white mature male rats weighing 200–220 grams. Animals in the experimental group (n=30) were exposed to daily smoke inhalation for 4 weeks, 4 hours a day, 5 days a week. Rats in the control group (n=30) were supplied with clean air into the chamber. The examination of animals exposed to smoke was carried out in two stages. At the first stage, the morphofunctional state of experimental animals was assessed 24 hours after the end of exposure. At the second stage — 60 days after exposure (long-term period). The examination included an analysis of indicators of the central nervous system: histology and morphometry of the brain.
Results. Analysis of the results of the studied indicators indicates a decrease in motor and exploratory activity in animals exposed to smoke, as well as impairment of the ability to navigate and spatial memory. In the tissue structure of the sensorimotor cerebral cortex, multiple foci of neuronophagia, an increase in the number of degeneratively changed neurons, the formation of glial nodules and expansion of perivascular spaces were found. At the same time, the results of the examination in the long-term period indicated the absence of complete restoration of the identified violations.
Conclusions. The results of experimental modeling revealed cause-and-effect relationships between exposure to forest fire smoke and disturbances in the morphofunctional state of the central nervous system.
Limitations. The study is limited to studying the effects of prolonged 4 weeks, 5 days a week, 4 hours a day, exposure to wildfire smoke on outbred male white rats.
Ethics. The study was conducted in compliance with the rules of humane treatment of animals in accordance with the Helsinki Association of the World Medical Association for the Humane Treatment of Animals (edition – October 2008) in accordance with the requirements of applicability to the protection of vertebrate animals or in another scientific research (ETS). No. 123), Directive 2010/63/EC of the European Parliament and of the Council of the European Union of September 22, 2010, on the protection of animals used for scientific purposes. Permission was obtained from the Local Ethics Committee of the Federal State Budgetary Scientific Institution VSIMEI to conduct experiments (protocol No. 32/19 dated May 10, 2019).
