MATHEMATICAL MODELING OF THE STRENGTH PROPERTIES OF LESSES BY THE METHOD OF CORRELATION-REGRESSION ANALYSIS
Authors: Tarasenko Elena
Published: April 2024

The strength properties of subsiding loess soils are considered in the mathematical modeling of their compaction by deep explosions. Soil compaction is carried out in order to eliminate their subsidence properties. Correlation and regression analyzes of the dependences of strength on the physical characteristics of loess were carried out, using the soils of the North Caucasus as an example. The correlation dependence of the specific cohesion and the angle of internal friction on the physical characteristics of the subsidence soil is established. Correlation coefficients were obtained for various indices of moisture content and loess density. The studies were carried out before and after soil compaction in this way. Both positive and negative correlations between the studied characteristics of subsiding loess soil were recorded. With an increase in moisture, a high correlation was observed with the strength characteristics of the soil before and after its compaction by deep explosions. The equations of regression of specific cohesion and the angle of internal friction on soil moisture and density are constructed. The reliability coefficients of approximation of theoretical regression equations and experimental data demonstrate high values. The regression equations of specific adhesion and the angle of internal friction on soil moisture showed that the values of strength characteristics increase with decreasing values of soil moisture. The regression dependence of the specific cohesion and the angle of internal friction on the density of subsidence loess has been studied. It has been established that an increase in the values of strength characteristics was recorded with an increase in the density of loess soil before and after its compaction by deep explosions. The constructed regression equations make it possible to predict the strength characteristics of loess at the stage of designing the bases and foundations of construction objects.
New Challenges and Prospects of the Eurasian Economic Commission as a Negotiating Platform
Authors: Koktysh Kirill E. , Renard-Koktysh Anna V.
Published: April 2024

The study is devoted to the cognitive analysis of the current state of the Eurasian Economic Commission, which is the main institution of integration of the economies of the Western Eurasia. Deconstruction of the European principle of the “four freedoms” that was laid down in the basis of the EAEU allows authors to conclude that further implementation of the latter will lead to the reproduction of the EU’s weaknesses that have become obvious today. Moreover, it will lead to internal conflicts, primarily between corporations, which will be mainly Russian, and the member states. The predictable result will be a decrease in the functionality of the Eurasian Union, which has already taken noticeable forms. It produces the obvious risks of turning of this important negotiating platform into an artifact that does not meet the challenges that arose with the beginning of Russia’s Special military operation. The authors see a way out in «balancing» the principle of «four freedoms», which de facto leads to redistribution of resources in favor of corporations, with the principle of security. The extrapolation of latter to the economic sphere can allow not only to strengthen the regulatory role of states, but also to move to the creation of a production circuit within the Eurasian Economic Union based on the common system of division of labor. In their theoretical constructions, the authors appeal to the successful experience of China, which managed to introduce a system of moral and ethical restrictions for business, and thereby managed to make profitable a «long» investment focused not on the consumption of an individual, but on the prosperity of society as a whole.
The view on the Situation in Afghanistan in the Chinese Media within China’s National Security
Authors: Dolokhova Anastasia D. , Soboleva Elena D.
Published: April 2024

The withdrawal of US troops and the rapid takeover of Kabul by the Taliban (recognized as a terrorist organization and banned in the Russian Federation) in Afghanistan in 2021 shocked the world community. Even though the PRC actively opposes international terrorism, which the Taliban movement (recognized as a terrorist organization and banned in the Russian Federation) is accused of supporting, it has become one of the few countries that have begun to cooperate with the new Afghan regime. In the light of these events, China’s view of the situation in Afghanistan is puzzling, in particular, we are interested in how these events are reported in Chinese press. In this paper, first, we trace the evolution of the PRC’s official position on Afghanistan, and then, using frame analysis, analyze the coverage of the events of 2021 in the PRC by focusing on three authoritative newspapers, Chinese language versions of “People’s Daily”, “Global Times”, and “The Paper”. Our study demonstrates that the Chinese press supports China’s foreign policy in general and its policy in Afghanistan in particular. Stability in Afghanistan and cooperation with the Taliban (recognized as a terrorist organization and banned in the Russian Federation) on issues of Uighur separatism are important for China’s national security. In the Chinese media, the Taliban (recognized as a terrorist organization and banned in the Russian Federation) are not presented as accomplices of terrorism, which China is fighting within the framework of the Shanghai Cooperation Organization but are described as representatives of the Afghan people who aim to restore the security and stability in the country. When discussing the Taliban (recognized as a terrorist organization and banned in the Russian Federation) takeover in the Chinese media, the focus is often not on the crimes of the new regime - repression, abuse of power, restriction of rights, but on shortcoming of the US policy. The latter reflects an important discursive practice in the Chinese media, “othering” the United States.
Central Asia: Region’s Potential and New Challenges
Authors: Zhiltsov Sergey S.
Published: April 2024

Traditionally, Central Asia is associated with a favorable geographical location and significant natural resources. These factors are of interests for the West, Russia, and China in the region. Meanwhile, the potential of Central Asian countries leaves many questions unanswered, as they face many regional challenges. The aim of the study is to identify the geopolitical and economic potential of the Central Asian countries, as well as to identify the challenges that the states have faced in recent years. A special attention is paid to the water and energy issue, which remains the most pressing problem for the whole region. In the conclusion, the author identified two of them: the persistence of economic difficulties in the development of Central Asian countries, which to a certain extent act as economic competitors, as well as the increased influence of extra- regional actors on the countries of the region.

Humanitarian import substitution: Some results and current tasks of the Russian social science
Authors: Khagurov T. A.
Published: April 2024

The relevance of the issues under consideration is determined by the recent fundamental social-political transformations associated with the exacerbation of a complex set of cultural, civilizational and, thus, intellectual contradictions between Russia and the West. These contradictions force both the Russian society and the Russian social science to reconsider the results of the last thirty years and to predict future scenarios, including intellectual ones. The article summarizes some results of the development of the Russian social science in the post-Soviet period and discusses (at least invites to a discussion) the possible contours of its further development according to the new logic of social processes. The article considers both the achievements of the Russian social-humanitarian thought in the post-Soviet period and its problems, primarily the loss of intellectual independence due to the uncritical borrowing and dogmatization of many Western intellectual models, some of which were created to understand a different social-cultural reality, and others were initially an intellectual weapon against the USSR (Russia). The author proposes the concept of “humanitarian import substitution” as a possible guideline for further development, which should be implemented on the principle of avoiding extremes: on the one hand, uncritical denial of the generally significant achievements of the Western social science and humanities; on the other hand, dogmatization of the ideas of Russian social scientists. The author considers as a resource for such “substitution” the largely untapped analytical and explanatory potential of the Russian literary tradition that can become a theoretical-methodological basis for many social and humanitarian models and concepts.
The state in search of intellectual resources: The image of scientist in the perception of Russians
Authors: Lavrov I. A. , Kryshtanovskaya O. V. , Samokhina M. V.
Published: April 2024

Under global challenges, the Russian state looks for ways to develop the national intellectual potential as a guarantee of technological sovereignty and country’s competitiveness. National research universities are supported, grant mechanisms for research activities are implemented, and programs for attracting and promoting young scientists are adopted. However, some objective indicators show persistent problems in the academic sphere: the number of research staff declines; “brain drain” continues; the number of graduate students and people who defended the thesis is not enough to solve the key problems of the state. The article considers social representations of the prestige of the scientific profession and the image of the scientist as factors that have a negative impact on human resources in the academic field. The research consisted of two stages: 1) 21 focus groups in 7 large Russian cities to identify the prestige of the scientific profession among three generations; 2) 207 interviews with students of Moscow universities (as the main source of personnel for scientific activities) to get a more detailed understanding of the image of the scientist. According to the results of the study, none of three Russian generations consider the profession of the scientist prestigious (inferior to politicians, businessmen, artists, bloggers, and IT specialists). The youth feel social injustice more acutely: they note the exceptional importance of scientists for national development, outstanding intelligence and complexity of this profession, but consider scientists an undervalued and low-income group. The image of the scientist is extremely distanced from the youth and is not an attractive vector of social mobility. One of the key reasons for the current situation is the absence of scientists in the Russian information space. Neither on television, nor in cinema or on social networks the image of the scientist is attractive to younger generations. If efforts are not made to eliminate this contradiction, the shortage of personnel in science will worsen, which would jeopardize the implementation of Russia’s national development plan.
The emergence of synergistic complexities in Russia: A request for new university courses
Authors: Kravchenko S. A
Published: April 2024

The article explains the request for new approaches in the higher education as determined by the emergence of the “order out of chaos” (I. Prigogine) in the form of synergistic complexities. Their underestimation during perestroika and liberal reforms led to the crisis in the educational system and society. Until now, these actual issues have not been sufficiently represented in the educational programs of universities: students need synergistic knowledge that connects the achievements of social sciences, humanities and natural sciences and allows to analyze the nature of complex, non-linearly realities and manage them. The author considers the following synergistic realities: social-techno/digital-natural hybrids, complex spaces and time, interference risks and hybrid vulnerabilities, complex social identity, complexities of social consciousness, good and evil, scientific knowledge and education. To analyze the nature of synergistic realities, the author suggests a theoretical-methodological combination of three meta-paradigms: the theory of synergetics, which includes social-humanitarian and natural-scientific knowledge; theories that study the mutual influence of global and national-local factors; theories of nonlinear development and metamorphization. The author makes conclusions about the need for interdisciplinary and post-disciplinary courses for the study of synergistically complex realities, focusing on the Russian cultural specifics, which would allow to equip students with knowledge about complex causality; to form a creative personality with a set of cultural and professional competencies necessary for the preservation and reproduction of the Russian synergistic complexities with their national-cultural specifics; to develop a humanistic worldview and a socially responsible attitude towards society, macroand micro-worlds of nature and technological innovation, thus, contributing to the sovereign development of the country.
Ejemplo versus peligro: Modernidad/reivindicación en Facundo, Bases, Iniciativa de la América y Nuestra América. Una mirada desde el globocentrismo y la colonialidad (Latinoamérica, siglo XIX)
Authors: Guerin Boggle Brandom
Published: April 2024

El presente artículo analiza, desde una perspectiva ligada al globocentrismo y la colonialidad, la pugna del pensamiento latinoamericano entre las corrientes modernizadora e identitaria a partir del análisis de cuatro obras: Facundo, de Domingo Sarmiento; Bases, de Juan Bautista Alberdi; Iniciativa de la América, de Francisco Bilbao; y Nuestra América, de José Martí. De las dos primeras, clásicas del pensamiento modernizador, se rescata el ferviente occidentalismo, la alabanza al modelo anglosajón de desarrollo y sus argumentos para validar o adecuar su inserción en el continente. De las dos últimas se examina la advertencia frente al riesgo de avance noratlántico, la poca cognición de aquello en la sociedad latinoamericana, y las soluciones o cambios que permitirían la reivindicación continental. Sostenemos que la distinción entre ambas tendencias radica en el aliento de un modelo anglosajón globocéntrico en América amparado en fundamentos propios de la colonialidad del poder/saber por parte de los civilizatorios, en contraparte al peligro para la libertad y soberanía que ven en aquello los identitarios, a la par de una poca conciencia en la sociedad americana ante el problema que motiva la necesidad de sensibilizarles.
Genome-wide mapping, allelic fingerprinting, and haplotypes validation provide insights into the genetic control of carbon dioxide responsiveness in rice

Published: April 2024

Plant density significantly impacts photosynthesis, canopy structure,
crop growth, and yield, thereby shaping the [CO ]
fertilization effect and intricate physiological interactions in rice.
An association panel of 171 rice genotypes was evaluated for
physiological and yield-related traits, including the cumulative
response index, under both normal planting density (NPD) and low
planting density (LPD) conditions. LPD, serving as a proxy for elevated
atmospheric [CO ], significantly increased all
trait values, except for harvest index, compared to NPD. For the
genome-wide association study, 386,817 high-quality SNPs were
considered, employing both single-locus and multi-locus models, which
collectively identified 172 QTNs, including 12 QTNs associated with at
least two different traits under NPD or LPD conditions. A significant
r­elationship between the percentage of favorable alleles in the
genotypes and their performance under NPD and LPD conditions was
observed. Potential haplotypes were validated using genotypes with
contrasting [CO ] responses, grown under LPD and
Free-Air CO Enrichment facility. These findings can
enable efforts to selectively breed genotypes with favorable alleles
and/or superior haplotypes for enhancing [CO ]
responsiveness in rice. Climate smart rice varieties, with increased
[CO ] responsiveness, have the potential to
simultaneously enhance grain yield and quality while mitigating losses
induced by high night temperatures.
Comprehensive profiling of the whole plant volatilome in Arabidopsis : Exposing dynamic tissue-specific VOC fingerprints linked to the plant’s adaptation to its environment.

Published: April 2024

Elaborate intra- and interkingdom communication systems have evolved in
plants, where volatile organic compounds (VOCs) are integral signalling
molecules. An investigation into the intricate realm of plant VOCs was
undertaken in this study, confirming known and exposing new roles of
VOCs in the complex mechanisms employed by plants to adapt to their
environment and regulate development accordingly. An untargeted analysis
of VOC data from seven distinct Arabidopsis tissues acquired
using the high throughput, sensitive technique known as Headspace Solid
Phase Micro-Extraction Gas Chromatography coupled with Mass Spectrometry
(HS-SPME-GC/MS) was deployed to explore the whole plant volatilome.
Improved analytical pipelines enabled new analyses of Arabidopsis
datasets revealing an exceptionally dynamic plant volatilome consisting
of 197 emitted VOCs, with 114 being detected in Arabidopsis and
ten in planta for the first time, thereby expanding the
repertoire of detectable VOCs, and quantifiable VAs. A high degree of
tissue-unicity among VOCs emerges, offering unique chemical fingerprints
for flowers, roots, leaves, siliques, and seeds. This work not only
enhances our understanding of plant development and stress tolerance but
also holds promise for leveraging the plant volatilome to improve
agricultural practices and crop production.

Published: April 2024

Diabetes mellitus (DM), a chronic metabolic disorder associated with
hyperglycemia and other complications, is one of the five priority non
communicable diseases of global interest with unprecedented rise in
developing countries. Whereas, the current treatment with insulin and
oral hypoglycemic agents is aimed at managing the hyperglycemia and
associated complications, there is need to explore other critical
pathways in the pathogenesis of DM that can act as potential drug
targets with better treatment outcomes. This study comprehensively
explains the role of cellular and molecular elements, like
hyperglycemia-induced oxidative stress, endothelial dysfunction, and
Nuclear Factor Kappa B (NF-κB)’s involvement in inflammation and immune
regulation, in the onset of DM. With bioactive compounds from natural
products gaining popularity as novel drug molecules due to their diverse
pharmacological actions, the study also extensively explores the
prospective therapeutic benefits of curcumin (CUR), a bioactive compound
known for its antioxidant, anti-inflammatory, and hypoglycemic
properties, in addressing diabetic complications, predominantly via the
modulation of the NF-κB pathway. The findings reveal that CUR
administration effectively lowered blood glucose elevation, reinstated
diminished serum insulin levels, and enhanced body weight in
Streptozotocin -induced diabetic rats. CUR exerts its beneficial effects
in management of diabetic complications through regulation of signaling
pathways, such as CaMKII, PPAR-γ, NF-κB, and TGF-β1. Moreover, CUR
reversed the heightened expression of inflammatory cytokines (TNF-α,
IL-1β, IL-6) and chemokines like MCP-1 in diabetic specimens,
vindicating its anti-inflammatory potency in counteracting
hyperglycemia-induced alterations. CUR diminishes oxidative stress,
avert structural kidney damage linked to diabetic nephropathy, and
suppress NF-κB activity. Furthermore, CUR exhibited a protective effect
against diabetic cardiomyopathy, lung injury, and diabetic
gastroparesis. Conclusively, the study posits that CUR could potentially
offer therapeutic benefits in relieving diabetic complications through
its influence on the NF-κB pathway.

This paper deals with the existence of weak solutions of the system that
describes the two-phase two-component fluid flow in porous media. Both
two-phase and possible one-phase flow regions are taken into account.
Our research is based on a global pressure, introduced in3, an
artificial variable that allows us to decouple the original equations.
We introduce another variable that does not have physical meaning in
one-phase region and name it capillary pseudo-pressure. By using these
two variables we rewrite system’s equations in a fully equivalent form.
This allows us to derive an existence result for weak solutions in more
tractable way compared to15.

Background: Diabetes Mellitus (DM) and Hypertension (HTN)
constitutes a huge burden for low-income countries, so a screening
program for identifying those at risk or at the early stages can be
beneficial. The aim of the study is to screen Albaraha residents for DM
and high blood pressure. Methods: A cross sectional community
based study, which was conducted at Albaraha locality. A screening
campaign was carried out for DM and HTN. A snowball sampling method was
used. Blood pressure of > 130/90 was regarded as HTN and a
Fasting blood glucose of > 126 mg/dl with a positive risk
factor was considered to be DM. An interview was conducted to asses for
risk factors. The collected data were entered into an Excel form,
processed then analyzed using Statistical Package for Social Science

Published: April 2024

This study aims to verify the effects of interpersonal relationships and social support factors on the life satisfaction of elderly people over 65 years old divided into three age groups while using Carstensen & Charles' Social Emotional Selection Theory as a foundation. Data from the 8th year supplementary survey of the National Retirement Security Panel (KReIS) were used, and the data of 1,117 elderly people aged 65 years of age or older who were living alone were extracted and analyzed. First, there were differences in educational background, number of children, economic activity, and average monthly income among the examined age groups. Interpersonal relationships, social support factors, and life satisfaction were also all found to differ between the three age groups. Second, it was confirmed that higher social support factors were associated with higher life satisfaction in all age groups. This study is meaningful in that it analyzed the effects of interpersonal relationships and social support factors on life satisfaction according to the characteristics of each age group of elderly people living alone, and based on these results, this study suggested practical intervention measures for social welfare as well as follow-up studies that should be conducted to improve life satisfaction among elderly people living alone
An update on apple chlorotic leaf spot virus status of sweet cherry in Bulgaria
Authors: Borisova Aneliya
Published: April 2024

The sweet cherry (Prunus avium L.) is one of the most important stone fruit
species in Bulgaria. The cherry is susceptible to many viruses. To gain a
better insight into the phyto-virologic status of sweet cherry, a survey for
the presence of apple chlorotic leaf spot virus (ACLSV), cherry leafroll
virus (CLRVR) and raspberry ringspot virus (RpRSV), in addition to
ilarviruses, was carried out in 32 commercial and 6 collection orchards in
ten regions of Bulgaria between 2017 and 2022. A total of 1503 sweet cherry
samples were collected from symptomatic and symptomless trees. These samples
were tested by cocktail ELISA for ACLSV and DAS-ELISA for CLRVR, RpRSV ?nd
additionally for prune dwarf virus (PDV) and prunus necrotic ringspot virus
(PNRSV) to detect mixed infections. Of the three viruses studied, only ACLSV
was detected in commercial and collection sweet cherry orchards in all
regions with intensive cherry cultivation in Bulgaria, in addition to
ilarviruses. The extent of ACLSV virus infection was 8.8%. Single ACLSV
infection was the most common, affecting 79.6% of infected sweet cherry
trees, followed by ACLSV and PDV (14.4%) and least frequently by ACLSV and
PNRSV (6.0%). The presence of ACLSV in orchards of different ages, including
?young? orchards, indicates that virus-free propagation material must be
used when establishing new orchards to prevent the spread of pathogens with
the planting material.

Published: April 2024

This paper was written to demonstrate the value of using nanofluids for cooling high power transformers while also providing current techniques for business and academia. A numerical analysis of the improvement caused by the cooling of a high voltage transformer using nanofluids has been done. A tank with a temperature source inside and a charge of mineral oil-barium titanate nanoparticles is used to study natural-convection. This study investigates the effects of variables on the thermal efficiency of the tank, including the thermal Rayleigh number and volume fraction. The results show that quenching varies with low and high Rayleigh thermal numbers and depends on the volume percentage of used nanoparticles. The effects were illustrated in thermal transfer rate representations as functions of the thermal Rayleigh number (Rat = 103 and 106) and the solid volume particle from the nanoparticles (0% ? ? < 10%). The findings showed that improving the solid volume particle of the nanoparticles by 10% causes the fluid being utilized to become more effectively conductive, which improves the rate of heat transfer by roughly 10% when compared to the case of the base fluid.

Published: April 2024

The temperature drop process of waxy crude-oil in an oil tank is an unsteady natural-convection process involving multi-substance coupling, multi-heat transfer coupling, phase transformation, solid-liquid interaction, rheological change, fluid-solid coupling and turbulence, and the heat transfer process is highly complicated. According to the influence of the phase change process of waxy crude-oil on the heat transfer process, based on the new three-phase partition method, the phase change heat transfer model of waxy crude-oil in an oil tank was established, and the finite volume method was used to carry out the equation discretization and solution. Through numerical simulation, the evolution laws of the temperature field, flow field, and growth of the condensate layer during the cooling process of oil in the tank were analyzed. The results had theoretical guidance and significance for the scientific design of the oil tank?s thermal insulation structure.

Published: April 2024

The chimney junction of solar chimney power plant was the main element coupled the solar collector to the chimney. It presents an important impact on the SCPP design, which is change the air-flow direction. The numerical code ANSYS Fluent was used in this study to investigate how the chimney Junction radius affected the local air-flow characteristics and the turbine site. Using test results from an experimental prototype constructed in Sfax, Tunisia, the numerical method was validated and verified. For four set-ups with various chimney connection radii, thermodynamic variables such as distributions of the total pressure, static temperature, static pressure, and magnitude velocity were examined. Also, the influence of these parameters on the air turbulence was analyzed through the transition zone. The results showed that the local air-flow characteristics and therefore, the SCPP efficiency were significantly impacted by changes in junction radius. Besides, the maximum velocity inside the chimney was varied and changes its location when the junction radius changed. These facts affect directly the overall turbine expenditure, which represented in terms of structure and power capacity.
Simulation study on effect of nozzle geometry on flameless combustion of non-preheated methane gas
Authors: Zhang Yazhu , Liu Congxi , Huang Zhuben , Huang Jun , Zhang Li , Li Kai
Published: April 2024

In this paper, the effects of different burner configurations on the characteristics of flameless combustion were evaluated by comparing the temperature field, NOx, OH, and H2CO at different burner inlet velocity and angles through a combination of experimental and numerical simulations. The results show that increasing the burner inlet angle and gas velocity is imperative in achieving the flameless combustion, increasing the re-circulation rate in the furnace, making the temperature distribution in the furnace uniform, and reducing the emission of NOx at the end of the furnace. During the simulation of flameless combustion, it was found that OH radicals and H2CO radicals were well correlated with the reaction exothermic zone, and the Reynolds number was positively correlated with the re-circulation rate in the furnace. With the increase of Reynolds number, the entrainment rate of flue gas increases, and the combustion state is closer to flameless combustion. When re-circulation rate Kv >2, combustion becomes flameless. Through the summary analysis of the data, it can be found that there is a critical Reynolds number for the burner to achieve flameless combustion, and flameless combustion occurs only when the Reynolds number is greater than 1.0?104.

Published: April 2024

The main control room serves as a refuge for staff in a nuclear power plant in the event of an accident. To determine whether the control room can meet habitability requirements under accident conditions, this study utilized CFD methods to establish a habitability model of the main control room under such conditions. The changing trends of temperature and velocity near personnel were analyzed. The numerical results indicate that the building envelope significantly contributes to reducing the indoor temperature. The average wall temperature measured at 72 hours was 27?C, with an average temperature increase of 4?C. The highest average ambient temperature in the main control room occurred at 24 hours. At this time, the indoor ambient temperature reached approximately 34.62?C, with a temperature increase of 11.62?C, while the wind speed near the personnel remained below 0.2 m/s, meeting habitability requirements for personnel under extreme conditions.

Published: April 2024

Few studies have examined how EFL teachers, as language teacher educators, perceive their participation in a particular online professional learning community (PLC) despite the growing body of research on PLC in educational settings. The current study delved into the teacher professional development of EFL teachers in higher education settings. Semi-structured interviews were used to collect data and then narratively evaluated. The data were thematically analyzed. The results point to a few advantages teacher educators experience when participating in online PLC, which ultimately improves their competency in teacher professional development. The result brought to light that online PLC activities in Indonesia facilitated teacher educators' professional development in many aspects. Understanding the findings in the present study could motivate English teachers, be they in secondary or post-secondary education contexts, to always improve their pedagogical knowledge through PLC. Stories shared by the participants in this study inform pedagogical impacts for redesigning curricula that specialize in writing practice for PhD students.

Mathematics is one of the primary disciplines in education that can be used to measure students' abilities in learning and understanding scientific equations. This research explores the effectiveness of grouping methods in teaching mathematics at the high school level and its impact on students' scientific literacy. Using data analysis and descriptive methods, this study gathered responses from 60 high school mathematics teachers in Kurdistan who completed questionnaires on using grouping methods in teaching. The results show that all teachers found the grouping method to be an effective way to teach mathematics, improve student understanding, and facilitate student cooperation and critical thinking. The implications of this study include providing beneficial teaching methods for teachers and new insights into the practical and theoretical literature on group learning in mathematics. This research contributes to developing more effective mathematics teaching strategies in high schools, focusing on group learning approaches.
COMPARATIVE ANALYSIS OF THE EFFECTIVENESS OF USING HISTOLOGICAL AND PHYSICAL-OPTICAL METHODS OF INVESTIGATING OF THE TIME OF HEMORRHAGE FORMATION IN THE SUBSTANCE OF THE HUMAN BRAIN

Important attention in forensic medical practice is given to the solution of issues that arise during the examination in thecase of traumatic brain injury (TBI), as this type of injury leads to high mortality and disability. Conducting an autopsy of thebody of the deceased, whose death occurred from a TBI, there are cases when the injury occurs as a result of a fall of a person who previously developed a cerebral infarction, and sometimes vice versa. In this case, it is important to accurately verify the primary cause of death, therefore, timely and objective determination of the time of formation of a hemorrhage in the human brain is necessary.The purpose and tasks of the research. To evaluate the possibility of detecting time of formation of a hemorrhage of traumatic and non-traumatic genesis by the generally accepted histological method and polarization phase microscopy, and to compare their eff ectiveness.Research materials and methods. For the study, human brain samples were selected from 140 deceased individuals whosedeaths occurred between 1 and 3 days after the onset of bleeding, according to medical records. As a control group, human brain samples were selected from 40 individuals who died of coronary heart disease. Light microscopy was performed by preliminary staining of histologic specimens according to the Perls method. Phase polarization tomography of the samples was performed using a Stokes polarimeter.Research results. Stained human brain preparations of the experimental and control groups were examined and analyzedand it was found that hemosiderin was not present in all experimental samples (only in 31 out of 40 samples were present). It was not possible to establish the corresponding time dependences of the age of the formation of hemorrhages, regardless of the genesis, since the random appearance of the pigment in the experimental samples is noted at diff erent time intervals. Analytical processing of the results of the statistical processing of the topographic structure of tomograms of the anisotropy of linear dichroism of the fi brillar networks of samples of the deceased from the experimental and control groups revealed a wider time range of sensitivity of this method to destructive changes in nervous tissue, in comparison with the polarimetric methods used in previous studies. As a result, there is an accelerated temporal decrease in the absolute values and the range of dispersion of the anisotropy of linear dichroism value with increasing time since the formation of hemorrhage.Conclusions. Polarization- phase microscopy has shown a signifi cant advantage in its use in comparison with the goldstandard – the Perls’ staining method for determining the time of hemorrhage formation in the human brain.

The purpose of this research is to find out how it is implemented as well as the success factors and inhibiting factors of the ZIS fundraising strategy through the use of the QRIS non-cash payment system at BAZNAS Banyumas Regency. The type of research used in this research is field research, which is descriptive qualitative. Data collection techniques used in this study are interviews, observation, and documentation. Data analysis used in this study includes data reduction, data presentation, conclusion, and verification. Test the validity of the data in this study using triangulation techniques. This research shows that BAZNAS Banyumas Regency in collecting ZIS funds through the QRIS non-cash paid system, applies four strategies, including 1) The segments and targets of QRIS muzakki are the millennial and z generations, 2) Prepare and provide competent human resources, 3) Building a communication system through social media and print media, 4) Develop and implement online zakat services through QRIS. In its implementation, the program attracts the convenience of transactions through QRIS, fosters a sense of empathy for donors with the mustahik distribution and utilization program, collaborates with BSI, provides good services in the form of zakat consultations, reports on the collection and distribution of ZIS funds to muzakki, proof of ZIS deposits, and pray for and thank you note. The success factors include online zakat services, utilizing social media and print media to promote ZIS payments through QRIS, and QRIS can be accessed 24 hours. The inhibiting factors are the lack of public awareness of paying ZIS, public understanding regarding digital technology, and the lack of special socialization of ZIS payments through QRIS.
Exercícios de leitura pessoal em livros escolares do Brasil e de Portugal
Authors: De Sá Ana Paula dos Santos , Leite Carlinda
Published: April 2024

O artigo analisa a frequência e o modo como a leitura pessoal é trabalhada no eixo literário de livros escolares do Brasil e de Portugal. O corpus foi constituído por 73 exercícios de compreensão textual pertencentes a dois manuais de Português do 4º ano da escolaridade básica, sendo um exemplar de cada país. A análise, fundamentada na técnica de análise de conteúdo, foi composta pelas etapas de mapeamento e de categorização das amostras, e seus resultados foram discutidos quantitativa e qualitativamente. Os resultados apontam que são pouco frequentes exercícios que solicitam a expressão da subjetividade. Em ambos os casos, são preponderantes atividades de viés pessoal centradas no gosto, na concordância/discordância e na emissão de opinião, sendo raramente propostas questões sobre a identificação/não identificação com o texto. O maior ponto de divergência entre o manual brasileiro e o português diz respeito ao lugar ocupado pelas perguntas pessoais na sequência didática, o que suscitou reflexões sobre as implicações de se promover a expressão da subjetividade antes e/ou após a leitura.
