AbstractThis research aims to analyze how the synergy between family, school, and community education can strengthen the understanding and practice of religious moderation and the supporting factors, forms, and effects of this synergy. The research was conducted at Sindang Jati, Rejang Lebong, Bengkulu using qualitative methods and a phenomenological approach. The data collection technique used snowball sampling for interviews, accompanied by observation and documentation. The data were analyzed with a phenomenological model through epoch and ideation. The research results show that close collaboration between education received in the family, at school, and in society can significantly improve understanding and practice of religious moderation. These findings confirm that the synergy between these three components provides a large positive impact, in line with the social theory proposed by Parson and Brofenbrenner. Factors such as shared goals, effective communication (associative interaction), parental involvement, school commitment, and community trust and roles are essential in strengthening this synergy. In line with Murphy's law, the synergy of the three educational centers minimizes opportunities for immoderate attitudes and actions to grow.AbstrakTujuan penelitian ini untuk menganalisis bagaimana sinergisitas antara pendidikan keluarga, sekolah, dan masyarakat dapat menguatkan pemahaman dan praktik moderasi beragama, faktor-faktor pendukung, bentuk dan pengaruh sinergisitas tersebut.

Authors: Castejon-Ramirez Sandra , Pennington John , Beene Hayley , Hysmith Nicholas , Ost Shelley
Published: December 2023

Since the Monkeypox virus outbreak erupted in May 2022, infection has been reported across all ages. Few cases exist in the medical literature about Monkeypox infection in neonates, and little is known about its clinical manifestations, disease course, or side effects of available antiviral agents in this age group. In this report, we describe the case of a 10-day-old neonate from the southern United States who presented with fevers and generalized papulopustular rash. She was treated empirically as a febrile neonate but mpox infection was suspected early because of the characteristic exanthem and its similarity to her mother’s rash that she had developed a few days before the patient’s presentation. Oral tecovirimat was initiated on the third day of admission and mpox was later confirmed by polymerase chain reaction analysis. The patient tolerated oral tecovirimat well and experienced a favorable outcome without lasting effects of infection.

Published: December 2023

Introduction. The paradoxicality of which lies in the fact that with a lack of official institutional trust of the population in the authorities, it flows into informal, criminal and semi-criminal social spheres, into corrupt social ties and groups, and into the informal economy, shadow employment. The purpose of the article is to conduct a sociological theoretical and methodological analysis of the paradoxical forms of institutional social trust in Russian society in the form of corrupt and shadow economic ties.

Materials and Methods. Empirical data on the shadow labor market in the Russian Federation were obtained in the course of mass and expert surveys conducted in 2021 in 10 regions of the Russian Federation and 2 megacities. In the course of preparing this publication, general scientific, logical methods were used, structural-functional, sociocultural, anthroposociocultural, projective approaches in modern sociology, the method of sociological imagination, the methodology of analysis and the formation of “we-groups”.

Results. In the course of the authors’ research, it was found that such negative social phenomena as domestic and business corruption, shadow (informal) employment are a paradoxical form of expression of institutional trust in society. The paradox of the sociological correlation of corruption and shadow employment with institutional trust only at first glance seems illogical and contrary to sound scientific understanding. As a result of the analysis, the authors have revealed that with a lack of basic institutional trust of the Russian population in state and municipal authorities, social trust flows into informal, semi-criminal and criminal spheres. It has been proved that corruption and informal employment as forms of social practice become forms of expression of specific political trust based on strong social ties (blood related, kindred, friendly) in Russian regions. The authors’ team determined that corruption and informal employment are becoming a type of informal social self-organization of society, which close the gap between the political communications of the elite and the expectations of civil society.

Discussion and Conclusion. Corruption and the informal economy are becoming a paradoxical form of manifestation of situational, horizontal, institutional trust based on strong (blood related, kindred, friendly) ties, on the social ties of “we-groups”, on the atomism of the Russian regional society. This research can be practically used by sociologists, lawyers, criminologists, social psychologists, law enforcement officers of the Russian Federation.
Evaluating the impact of structure parameters on the acoustic performance of an exhaust muffler with shells
Authors: Mosa Ali I. , Putra Azma , Mahmood Hussein A.
Published: December 2023

Recently, environmental noise has arisen from various sources, such as those from exhaust mufflers of combustion engines found in cars, trucks, or power generators, which produce significant noise during their operation. Controlling the radiated noise from these mufflers is a major factor in improving acoustic comfort and minimizing the impact on the surrounding communities. Numerous research has been presented for this reason by modification of the internal structure of the exhaust muffler. The main objective of this work is to reduce the noise level emitted from exhaust mufflers. This can be achieved by adjusting structure parameters to attenuate the surrounding environment's radiated noise. Analysis of pressure-wave propagation has been done by building 3D models using COMSOL Multiphysics software. Different entities were conducted to investigate the influence of muffler shells and plate thicknesses on acoustic performance through the frequency domain to obtain better attenuation. SPL over a frequency band is presented, describing how the sound intensity varies at different frequencies within a given bandwidth. The results showed that increasing the muffler shell thickness improved the TL; this particularly causes a double value at a range above 1.2 kHz, where there are two distinct peaks at 1.3 kHz and 2.8 kHz. Additionally, it was found that increasing the muffler plate thickness reduces the TL whole range and moves the curve peak to higher frequencies.
This is because the pressure pulses that stimulate the shell plates would exert a more distinct influence on plates characterized by a reduced thickness, and the muffler structure thickness is correlated with its increased stiffness, resulting in an elevation of the frequency for this eigenmode

Published: December 2023

The object of this study is the relationship between the structural and technological parameters of feeders for loose materials and the characteristics of particle flows at their outlet, namely: productivity and the magnitude of pulsations. The existing designs of this type of equipment were analyzed, and the most common methods for simulating their operation were determined. A structure of a tubular-comb feeder has been proposed, the performance of which is compared with the well-known screw feeder. Computer models of both structures were built based on the discrete element method. The simulation was carried out in the EDEM 2017 software environment. It was established that the resulting models take into account the discrete nature of the movement of loose materials and allow conducting research taking into account the physical and mechanical properties of individual particles.
An experimental bench was fabricated for experimental verification of the modes of operation of the tubular-comb feeder. The performance of this type of feeder was determined for two pipe rotation speeds (6 and 10 rad/s). The amount of material flow pulsations in the outlet nozzle was also determined. The correspondence of the results of calculations based on the computer model to the real process was confirmed. The current study was carried out the steady modes of operation.
It was established that with equal overall dimensions and speeds of rotation of the working bodies, the productivity of the screw feeder is 5...5.2 times greater than that of the tubular-comb feeder. But the latter provides 7.3...16.4 times smaller magnitude of pulsations of the flow of loose material. This makes it possible to reduce the heterogeneity of mixtures, especially in the case of using such feeders as part of continuous mixing systems.
The results make it possible to analyze the operation of bulk material feeders and reduce their design time

Authors: Pylypenko Ihor , Kovalchuk Iryna , Tsyba Mykola
Published: December 2023

The object of research is granular composites based on zirconium-iron alginates and laponite. The task of research is to determine the influence of the Zr:Fe ratio on the structure of granular composites and efficiency of uranium (VI) removal from aqueous solutions. The influence of the zirconium and iron ratio on the parameters of the material's pore structure has been established, particularly on the change in the content of micropores within the matrix. The specific surface area of the materials ranges from 86 to 112 m²/g. The sorption properties of the composites regarding uranium (VI) have been investigated. The impact of the charge of surface groups and the form of uranium (VI) presence in sulfate solutions on their sorption characteristics has been demonstrated. The maximum adsorption capacity reaches 265.1 µmol/g at pH 6. It is shown that an elevated electrolyte content positively affects the efficiency of uranium (VI) removal in neutral and alkaline medium. It has been established that structural changes in the materials occur due to the intensive interaction of iron ions and alginate molecules, resulting in the formation of a dense gel-like structure. The mechanism of uranium (VI) removal is associated with the formation of surface complexes in the presence of electrolytes. The synthesized granulated composites exhibit improved removal efficiency of uranium (VI) under conditions of high mineralization of solutions, making them attractive for potential use as sorbents. The obtained results can be utilized in the development of effective methods for purifying water environments from uranium (VI) in high mineralization conditions, which is a relevant issue in the field of nuclear energy and the removal of radioactive substances from water systems

Authors: Subtelnyy Roman , Zhuravskyi Yevhenii , Dzinyak Bohdan
Published: December 2023

The object of research is the production of C9 hydrocarbon resins by oligomerization of oil refining by-products.
In the technology of hydrocarbon resins by free radical oligomerization, there is a disadvantage in the use of high temperatures and a long reaction time. The resulting products have a dark color, which limits their use in paints and varnishes.
The technology of hydrocarbon resins, which consists in the suspension oligomerization of hydrocarbons of the C9 fraction in an aqueous medium, at low temperatures and stirring, was studied.
N-substituted amino peroxides, which are characterized by a low temperature of use, were used as initiators. The raw materials used were C9 fractions of liquid gasoline pyrolysis products with an unsaturated compound content of 54.7 %.
The optimal conditions were established: temperature – 364 K, time – 180 min, Re=10120, initiator concentration – 0.064 mol/l, the share of C9 fraction in the reaction mixture – 25 %. Under these conditions, a light hydrocarbon resin with a color index of 20 mg I2/100 ml and a softening point of 352 K was obtained.
The use of amino peroxide initiators allows for the suspension oligomerization of the hydrocarbon fraction C9 at low temperatures (303–353 K) and within a short reaction time (180 min). This oligomerization technology makes it easy to remove excess heat and maintain isothermal conditions in the reaction zone. This prevents the development of side oxidation reactions that cause darkening of the product.
The research results make it possible to improve the process of oligomerization of the hydrocarbon fraction using new initiators and obtain light-colored hydrocarbon resins. This will reduce energy costs for production and improve the characteristics of hydrocarbon resins

Published: December 2023

The object of this study is a class B fire, which is extinguished with sprayed water. The subject of the study is the characteristics of class B fires when they are extinguished with sprayed water. Diffusion burning of a flammable liquid is considered as such a fire, and its extinguishing is carried out by cooling the flame. Heat and oxygen balance equations are used to build a mathematical model describing the fire extinguishing process. The components of the heat balance equation are the power of heat during heat release due to the chemical reaction of liquid combustion and the power of heat dissipated to the environment. The second component takes into account heat removal due to radiation, convection, and evaporation. The component of removed heat due to evaporation takes into account the Sreznevsky constant. The mathematical model that describes the process of extinguishing a class B fire is built in the class of models belonging to differential equations with constant coefficients. Analytical expressions were obtained for these static and dynamic coefficients, which include thermophysical, kinematic, and geometric parameters of the flame and fire extinguishing agent. To determine these characteristics, the constructed mathematical fire model was transformed using the integral Laplace transform. The dynamic characteristics of the fire were obtained in the time domain – the transient function of the fire, and in the frequency domain – the amplitude-frequency and phase-frequency characteristics of the fire. It is shown that the parameters of these dynamic characteristics should be determined experimentally. Experimental methods for determining parameters of dynamic fire characteristics have been devised. The presence of dynamic characteristics of class B fire makes it possible to spread the proven methods of the theory of control systems to design effective fire extinguishing systems
Exploring the power of heterogeneous UAV swarms through reinforcement learning
Authors: Albrekht Yosyp , Pysarenko Andrii
Published: December 2023

The object of research is heterogeneous and homogeneous swarms of unmanned aerial vehicles (UAVs). The primary focus of this study is the comparison between heterogeneous and homogeneous UAV swarms, examining their performance in a simulated environment designed using the Python Gym library. The research involves implementing reinforcement learning algorithms, specifically the Proximal Policy Optimization (PPO), to train and evaluate the swarms.
The central issue addressed by this research is to determine which type of UAV swarm – heterogeneous or homogeneous – exhibits better performance in a defined task. The chosen task involves searching for groups of objects in an unknown area, emphasizing the ability of the swarm to adapt and efficiently locate objects in dynamic environments.
The obtained results reveal an advantage for heterogeneous UAV swarms over their homogeneous counterparts. The heterogeneous swarm has a steeper learning curve and achieves higher rewards in fewer episodes during the training phase. The key finding indicates that the varied skill set within the heterogeneous swarm allows for quicker adaptation to changing environmental conditions. The superior performance of the heterogeneous swarm is attributed to the diversity of capabilities among its UAV agents, enabling them to leverage their individual strengths to achieve better overall performance in the given task.
The practical application of these results is contingent upon the task requirements and environmental conditions. In scenarios where tasks demand diverse skills and adaptability to changing conditions, heterogeneous UAV swarms are recommended. The results suggest their efficacy in applications such as search and rescue operations, environmental monitoring, and other dynamic tasks.
In conclusion, this research provides valuable insights into optimizing UAV swarm composition for specific tasks. The results contribute both theoretically and practically by highlighting the advantages of heterogeneity in swarm capabilities.

Published: December 2023

Purpose – This article compared machine learning algorithms in the context of satisfaction with democracy in Brazil. The models were trained with data from the Latinobarómetro survey, a private non-profit institution.
Theoretical foundation – The Support Vector Classifier (SVC), Random Forest (RF), and Artificial Neural Networks (ANN) classification techniques were described, followed by evaluation metrics, such as accuracy, precision, recall, f1-score and the area under a receiver operating characteristic (auc-roc).
Methodology – The data set was cleaned and the questionnaire was reduced to variables related to the local democracy index (IDL). Then, attribute transformations were performed, hyperparameters were analyzed and subsets with different class balances were created to evaluate the performance of the classifiers in different scenarios. Also, the attributes that most contributed to satisfaction with democracy were analyzed.
Results – The best classifier was RF for the class of those dissatisfied with democracy, however, the ANN and SVC techniques obtained better results in the class of satisfied individuals. Evaluating the most important attributes for satisfaction with democracy, it was identified that they are related to the country's economic situation and political and governmental issues.
Research implications – The models created were mainly able to identify people dissatisfied with democracy. The most important variables in this context were economy performance, government, political positioning, and democracy. This indicates directions for future studies and enables the development of strategies to change the perception of dissatisfied individuals.

Authors: Morozov V. N. , Luzin V. I.
Published: December 2023

Aim: to study the histological structure and histomorphometric parameters of the thyroid gland in rats in the period after the completion of the 60-day administration of tartrazine and the creation of a through defect in the tibiae.

Material and methods. One hundred and fifty white male rats were divided into five groups: groups T1 and T2 - 60 days of exposure to tartrazine at a dosage of 750 and 1500 mg/kg; group K+D – 60-day administration of saline solution and infliction of a defect in the tibiae; groups T1+D and T2+D – 60-day exposure to tartrazine at a dosage of 750 and 1500 mg/kg and causing a defect in the tibia. The histological structure and histomorphometric parameters of the thyroid gland were studied on days 3, 10, 15, 24 and 45.

Results. In the T1+D and T2+D groups, mainly small follicles, lined with cuboidal shaped cells, and in some of them - a flat or columnar shaped cells were detected in the center of the gland from days 3 to 15. Many thyrocytes had a vacuolated cytoplasm and an intensely stained nucleus. The heterogeneous colloid partially filled or was practically absent in the follicles cavity, anemia of the capillaries between them was determined. Singly areas of the organ parenchyma with a significant accumulation of lymphocytes were detected. Histomorphometric study showed a decrease in the internal diameter of the follicles, lumen-epithelial index and nucleo-cytoplasmic ratio and the raise in the height of the follicular epithelium and the area of the cytoplasm of follicular cells.

Conclusion. Sixty-day administration of tartrazine to rats and artificial traumatic bone injury leads, in comparison with the data of control groups, to a more pronounced change in the histological picture and morphometric data of the thyroid gland. The intensity and duration of changes are dosedependent: in the T1+D group, most of the qualitative and quantitative changes are smoothed out by 45 days, and in the T2+D group, many of them remain, and the body does not adapt to them.

Hasil menunjukkan bahwa surfaktan kationik, terutama pada konsentrasi tinggi 20-50 mM, memiliki efisiensi desorpsi yang lebih tinggi dibandingkan HCl, dengan efisiensi mencapai 80-90%. Mekanisme ini dikaitkan dengan kemampuan surfaktan kationik untuk membentuk misel ketika konsentrasinya melebihi nilai konsentrasi kritis misel (KKM) atau pada konsentrasi tinggi, yang memfasilitasi pertukaran ion dengan Cs pada permukaan MMTK10/Cs. Namun, tidak ada perbedaan signifikan dalam efisiensi desorpsi Cs antara BDAB dan DTAB, meskipun struktur hidrofilik BDAB lebih besar. Hal ini berbeda dengan penelitian sebelumnya pada montmorillonit lainnya dimana semakin besar struktur hidrofilik surfaktan yang digunakan, semakin besar interlayer montmorillonit terbuka akibat masuknya surfaktan besar itu pada interlayer sehingga mendorong desorpsi Cs dengan jumlah yang lebih besar. Akan tetapi pada penelitian ini tidak adanya perbedaan efisiensi desorpsi Cs dari kedua surfaktan lebih disebabkan karena struktur clay MMTK10 itu sendiri yang tidak memiliki kemampuan pengembangan atau pembesaran interlayer, akibat perlakuan suhu saat produksinya sebelum dijual kepasaran. Selain itu, kesamaan panjang rantai ekor hidrofobik antara BDAB dan DTAB berkontribusi pada kesamaan hasil desorpsi Cs dari kedua surfaktan tersebut. Kesimpulannya, sifat dan struktur surfaktan kationik mempengaruhi proses desorpsi Cs, tetapi karakteristik spesifik dari montmorillonit atau clay yang digunakan juga berperan penting dalam mekanisme desorpsi ini.Kata kunci: Desorpsi Cs, surfaktan kationik, interlayer montmorillonit.

El objetivo de esta investigación reside en analizar las competencias relacionadas con procesos contables, control interno y conocimientos generales en el ámbito de los contadores que operan en entidades religiosas en países interamericanos. A su vez, se busca identificar posibles diferencias en la medida que tienen y aplican estas competencias en los campos de procesos contables y control interno. Esta investigación se enmarca en una metodología cuantitativa correlacional que se enfoca en analizar diferencias. El grupo de participantes en este estudio consistió en un total de 90 contadores provenientes de entidades religiosas en países interamericanos. A través de un análisis de diferencias en las medias, se evaluaron las competencias individuales y la perspectiva global de la formación. Los resultados obtenidos reflejan que, en lo referente a las competencias generales de la licenciatura, no se manifestaron diferencias significativas (Z=-1.275, p=.202 y r=.134). Sin embargo, al abordar los procesos contables, se identificaron diferencias significativas (Z=-4.115, p<.001) caracterizadas por un  tamaño del efecto mediano (r=.433). Asimismo, al enfocarse en las competencias de control interno, se evidenciaron diferencias de menor magnitud (Z= -2.810, p=.005) en concreto en el ámbito de control interno, con un tamaño del efecto considerado pequeño (r=.296).

6 Şubat 2023 tarihinde, Doğu Anadolu Fay Zonu (DAFZ) üzerinde Yaklaşık 9 saat ara ile meydana gelen depremler sonucunda çok sayıda can ve mal kayıpları yaşanmış, yollar, köprüler zarar görmüş farklı türde (heyelan, kaya düşmesi, çamur akması) binlerce kütle hareketi meydana gelmiştir. Hatay’ın Altınözü ilçesine bağlı Tepehan köyünde Neojen yaşlı kumtaşı, killi kireçtaşı, kiltaşı ve marnlardan oluşan birim içerisinde gelişen heyelan 12.000 metrekarelik bir alanı etkilerken, 180.000 metreküpten fazla bir malzeme deprem sırasında oluşan heyelanla yer değiştirmiştir. Bu kadar büyük bir kütlenin yer değiştirmesinde depremlerin büyüklüğü yanında insan faaliyetleri de etkili olmuştur. Heyelanın meydana geldiği sahada Drone ile enine ve boyuna %70 bindirmeli sütunlar oluşturacak şekilde dijital görüntüler çekilmiştir. Bu görüntüler Agisoft yazılımında işlenmiş 60cm x 60cm piksel çözünürlükte Dijital Yüzey Modeli (DSM) ve Orto fotolar üretilmiştir. Heyelanın farklı yerlerinden alınan toprak numuneleri analiz edilerek genel toprak özellikleri belirlenmeye çalışılmıştır. Tepehan heyelanı depremlerin kütle hareketlerini (heyelanları) tetiklediği gerçeğinin somut bir örneği olması dışında yerleşim alanlarının doğal tehlikelere karşı (kütle hareketleri) güvenli hale getirilmesinde heyelanların izlenmesi ve haritalanmasının önemini bir kez daha göstermiştir. Depremlerin etkileri değerlendirilirken kütle hareketleri de dikkate alınmalıdır. Bu şekilde daha gerçekçi bir değerlendirme yapılabilir ve koruyucu önlemler daha etkili bir şekilde alınabilir.

Bu çalışmada, Giresun ili Alucra ilçesi Aktepe köyüne bağlı Belençayırı mahallesi sınırları içerisindeki traverten köprüsü incelenmiştir. Çalışmanın amacı, Aktepe Traverten köprüsünün oluşumu, jeomorfolojik özellikleri ve jeoturizm potansiyelini ortaya koymaktır. Çalışma arazi ölçüm, gözlem ve laboratuvar analizlerine dayanmaktadır. Traverten köprüsü, Alucra Çayı’nın yan kollarından Hayran Deresi vadisinin orta çığırında oluşmuştur. Traverten köprüsünün oluşumunda sahanın tektonik, litolojik ve jeomorfolojik gelişiminin önemli etkisi vardır. Çalışma sahasında farklı dönemlere ait kayaç toplulukları bulunmaktadır. Ancak traverten köprüsünün oluşumunda Jura-Alt Kretase yaşlı volkanikler ile kireçtaşının önemli etkisi vardır. Bu litolojik yapı içerisinde vadisini açan Hayran deresi, ilerleyen süreçte morfolojik taban düzeyini belirleyerek üstteki kireçtaşı tabakasından yağışlar sonucu sızan suların vadiye doğru akarak yamaç kaynaklarının oluşmasına neden olmuştur. Bu kaynaklardan çıkan ve kalsiyum bikorbonat bakımından zengin bu sulardaki karbondioksit yüzeye çıktıktan sonra ortam şartlarına bağlı olarak sudan ayrılmış ve kalsiyum karbonat birikerek Aktepe travertenlerini oluşturmuştur. Süreç içerisinde traverten kütlesi vadinin tamamını batı yönünde ilerleyerek kapatmış ve traverten köprüsünü oluşturmuştur. Laboratuvar analizleri sonucunda yüzeyden alınan travertenin %59.31 CaCO3 ve %40.69 kil içerirken, köprü altında oluşan sarkıtın %95.96 CaCO3 ve %04.04 kil içerdiği tespit edilmiştir. jeoturizm potansiyelini belirlemek amacıyla GAM Modeli ve Sayısallaştırılmış SWOT analizi sahaya uygulanmıştır. Bu analizler sonucunda sahanın yüksek jeoturizm potansiyeline sahip olduğu tespit edilmiştir.
