Electron Beam-assisted Synthesists, Structure and Luminescent Properties Porous Ceramics of MgAl2O4 and MgAlGaO4 Doped with Europium
Authors: Polisadova E.F. , Tran N.D.
Published: January 2025

Porous ceramics of MgAl2O4 (MAS) and MgAlGaO4 (MAGS) doped with europium were synthesized by ra- diation method. Radiation synthesis was performed with high efficiency within less than 1 s using radiation energy and mixture materials with no additives or any other materials used to promote synthesis. The synthe- sis method using a high-energy electron beam makes it possible to obtain refractory materials with high productivity, flexibly control the technological conditions of the process, and, accordingly, synthesize materi- als with desired properties. The structural properties of synthesized porous ceramics were investigated by X- ray diffraction (XRD-7000S diffractometer, Shimadzu), SEM. Results have shown that, the synthesized MAS have cubic structure and are in crystalline spinel MgAl2O4, while the synthesized double spinel MAGS con- tains two main phase components, MgAl2O4 and MgGa2O4. To study the luminescence properties of MAS and MAGS synthesized spinel doped with europium, photoluminescence measurements were performed. The photoluminescence spectrum of excitation of Eu3+ ions in spinel was monitored at λem = 615 nm (5D0→7F2). The PLE shows the f→f transition in the configuration of Eu3+ ions (at 393 nm (7F0→5L6), 463 nm (7F0→5D2)). The excitation band at 330 nm and 260 nm is characteristic of the charge transition between Eu3+ and O2- ions. The photoluminescence spectrum of the samples under excitation at 260 nm was studied. In the PL spectrum of spinel samples, the emission of Eu3+ ions are clearly visible. In the structure of the band with a maximum of 615, a peak is visible at 590 nm, characterized by the 5D0 → 7F1 transition. In the PL spectrum of samples, a weak spectral band appears with a maximum at 535 nm, characteristic of the emission of Eu3+ ions with the 5D1-7F1 transition. It is shown that the efficiency of radiation synthesis depends on the granulometric composition of the initial oxide powders.
Final ion formation and energy reemission upon a cascade decay of single vacancies in the K and L electron shells of atomic platinum

Published: January 2025

Cascade decay of single vacancies in 1s, 2s, 2p1/2, and 2p3/2 subshells of an isolated platinum atom are simu- lated by the method of construction and analysis of the cascade decay trees. The yields of final ions and the spectra of cascade electrons and photons are calculated. Mean charges of the final ions formed as a result of the cascade decays of 1s, 2s, 2p1/2, and 2p3/2 vacancies in the platinum atom are 7.75, 9.82, 7.80, and 7.95, re- spectively. The energies stored in final cascade ions, and the energies reemitted with cascade electrons and photons are calculated for the decays of each initial inner-shell vacancy. In the case of decay of vacancies in the 2s, 2p1/2, and 2p3/2 subshells, most of the energy initially acquired by the atom during the creation of an initial inner-shell vacancy is re-emitted by Auger and Coster–Kronig cascade electrons. In the case of 1s va- cancy decay, most of the energy is carried away by cascade photons, predominantly KL. The prospects of us- ing platinum-based agents as radiosensitizers in photon activation therapy of cancer are discussed.

Published: January 2025

The knowledge that is always being developed is knowledge about mathematics. Mathematics is a science that can train a person's thinking and logical abilities. Apart from that, research also focuses on other research in everyday life, especially the science of problem solving. Mathematics education is about connecting, designing, and creative learning. Sometimes studying mathematics in class can feel scary compared to other subjects, especially when it involves shapes. Abstract shapes have three-dimensional geometric concepts such as cubes, blocks, pyramids, prisms, cylinders and balls which are not easily understood with explanations or two-dimensional drawings. To overcome this problem, teachers should use teaching methods that increase students' conceptual understanding and make learning problem-based (PBL). The subject of this research is class VI of SD IT Uswatun Hasanah Padang Jaya. There are 29 students. The results of the research showed that 82.86% of students felt happy, so it was concluded that the use of PBL in mathematics education made students motivated in learning, especially class VI Bilal SD IT Uswatun Hasanah Padang Jaya.

O trabalho disserta a respeito da aplicação de um jogo pedagógico no ensino de Química como instrumento avaliativo do processo de aprendizagem dos estudantes, tendo como objetivo analisar a utilização do jogo pedagógico no ensino de Química como método avaliativo das aprendizagens dos estudantes. Contamos com 33 participantes, sendo estes estudantes do 3º Ano do Ensino Médio de Rede Pública. A pesquisa se configura como um estudo de caso do tipo explicativo de abordagem qualitativa, na qual, permeou responder o seguinte questionamento “De que maneira os Jogos Pedagógicos podem ser utilizados como instrumentos avaliativos no ensino de Química?”. A elaboração da prática realizada com os estudantes foi baseada nas cinco etapas do Percurso Metodológico Lúdico proposto por Nascimento (2022). Para a primeira etapa utilizamos de questionários para identificar os conhecimentos prévios dos estudantes, nos possibilitando identificar um déficit acerca do conhecimento deles sobre os conceitos de Química Orgânica. Identificadas as dificuldades, então iniciamos a segunda etapa, nesta foi realizada uma explanação dos conceitos que os estudantes demonstraram maior dificuldade, desta forma, conseguimos diminuir as lacunas no conhecimento acerca dos conteúdos. Nas etapas três e quatro, onde houve o registro da vivência do jogo, este foi analisado de acordo com os critérios propostos por Christie (1991) onde foi possível comprovar sua relevância e para analisar a vivência foram utilizados os corolários presentes na Teoria dos Construtos Pessoais (TCP) de Kelly (1963) e as Gerações da Avaliação de Guba e Lincoln (1989). Na quinta etapa houve o diálogo com os estudantes a respeito da prática. Durante a execução da prática podemos notar o quanto as atividades lúdicas auxiliam no aprendizado, visto a dedicação e aceitação que houve por parte dos estudantes, entretanto, é notório a escassez dessas práticas em sala de aula, portanto, ressaltamos a importância de incorporar jogos pedagógicos em estratégias de ensino e avaliação, pois estes podem fornecer uma maneira mais eficaz e envolvente de melhorar o aprendizado dos estudantes.
DENOTATION, CONNOTATION, AND MYTH THROUGH VERBAL AND NON-VERBAL SIGNS ON REPRESENTATION OF IDENTITY IN THE BIG SIX PREMIERE LEAGUE CLUB LOGOS
Authors: Arif Lutfi Rohmani  , Suyatman Ujang , Sakinah R. Myrna Nur
Published: January 2025

This study investigates the verbal and non-verbal elements within the logos of the "Big Six" Premier League clubs, aiming to uncover their denotative, connotative, and mythological meanings, and how these aspects represent identity. Using a qualitative descriptive approach based on Roland Barthes' semiotic framework, the research draws data from official club websites and documented literature. The analysis reveals that logos embody club identities through denotation, connotation, and myth, reflecting the historical, cultural, and social values associated with the clubs and their respective cities. Key components such as colors, symbols, and text, which are distinctive to each logo, play a significant role. This study contributes to the fields of cultural studies, semiotics, sports branding, and identity representation in visual communication and design. By exploring the semiotic depth of football logos, it bridges cultural semiotics and sports branding, uncovering often-overlooked narratives and enhancing both academic and fan perspectives on logo symbolism.
INTEGRATION OF ERROR CORRECTION MODEL IN TESTING THE INTERACTION EFFECT OF CREDIT GROWTH AND BANKING RISK MANAGEMENT IN INDONESIA
Authors: Wahyuni Adinda , Giriati Giriati , Wendy Wendy , Mustaruddin Mustaruddin , Mustika Uray Ndaru
Published: January 2025

This study explores the impact of market risk, operational risk, liquidity risk, and solvency risk, while also investigating the moderating effect of credit growth on bank performance. The Error Correction Model-Eagle Granger (ECM-EG) methodology was applied to data from 2014 to 2023. Findings indicate that, in the short term, market and operational risks significantly impact bank performance. In the long term, only solvency risk does not significantly affect bank performance. Additionally, credit growth moderates the relationship between market and liquidity risks and bank performance in the short term, while in the long term, it only moderates the relationship between market risk and bank performance. Our empirical findings demonstrate that effective risk management enhances bank performance. This research provides valuable insights for policymakers, researchers, and academics in fostering a conducive environment for corporate activities.
COMPARING PROCESS PERFORMANCE OF BIOLOGICAL AERATED FILTERS IN DIFFERENT SCHEMES FOR ADVANCED WASTEWATER TREATMENT
Authors: Vatralova Albena
Published: January 2025

Experimental results are presented from the performance of downflow biological aerated filters (BAF) in two technological schemes for advanced treatment of primary settled municipal wastewaters. In the first scheme two BAF with granular (Column 1) and crushed (Column 2) expanded clay media operate in parallel for oxidation of organic carbon compounds and ammonium nitrogen (biological nitrification). In the second scheme, Column 1 operates as a submerged anoxic biofilm reactor, which serves for the reduction of oxidized nitrogen (denitrification) in the recirculated nitrified effluent from Column 2. BOD5 and COD are not affected significantly from the changed purification scheme and the effect on these parameters is very high in both cases. In terms of inorganic nitrogen forms, the nitrification-denitrification system achieves more than twice the pollutant reduction compared to the nitrification-only scheme. At the same time, the increase in the total construction volume of the two-stage system would be less than twice due to the greater purification capacity of the anoxic reactor. This makes the two-stage scheme more economically efficient per unit volume of facilities.

Management of acute respiratory infections (ARIs) is a critical global health priority, as they continue to be the leading cause of morbidity
and mortality worldwide. With the advancement and promotion of novel products and tactics for preventing respiratory infections caused
by significant pathogens such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza, respiratory syncytial virus,
and pneumococcus, there is increasing evidence that interactions among these and other respiratory viruses and pneumococci can occur,
influencing colonization patterns and disease predisposition. This review examines the mechanisms involved in viral and bacterial coinfections
and how these interactions manifest in various respiratory infections in humans. Since infections resulting from viral-bacterial interactions
can aggravate the progression of the disease and complicate undiagnosed secondary infections, effective treatment tactics are crucial for
prevention. Immunotropic drugs play a key role in the treatment and prevention of acute respiratory infections by enhancing and bolstering
the body's immune response to intercept infectious pathogens.

Chronic hepatitis C remains a leading cause of liver cirrhosis and hepatocellular carcinoma. For the healthcare system, identifying new
serological prognostic markers for cirrhosis is a pressing need.
This article aims to present literature data on potential biomarkers of fibrosis, liver cirrhosis, and hepatocellular carcinoma. PD-L1 protein
regulates and modulates immune responses, preventing the onset of autoimmune processes. In chronic hepatitis C, it inhibits T-cell activity,
disrupting immune response production, and participates in fibroblast activation. FGF19 regulates bile acid metabolism, protein biosynthesis,
glucose, and glycogen metabolism. In liver cirrhosis development, dysregulation of FGF19 and its receptor affects the proliferation, migration,
and survival of hepatic cells. Data on the potential use of FGF19 as a biomarker for hepatocellular carcinoma are shown. TGF-β1 regulates
cell growth and differentiation, angiogenesis, and extracellular matrix formation. Most cells involved in fibrogenesis are controlled by TGF-β
Unlike other biomarkers discussed in the article, the level of this protein decreases as liver diseases progress from acute damage through
inflammation to fibrosis and cirrhosis. Continued study is needed to identify additional prognostic biomarkers for the risk of liver cirrhosis
development.

Acute bowel infections (ABIs) continue to represent a significant public health challenge. Predominantly, diarrheagenic viruses such as rotavirus
and norovirus constitute the primary etiological agents in current clinical settings. Nevertheless, bacterial pathogens, including Salmonella,
Campylobacter, Escherichia, Shigella, and Yersinia, remain significant contributors to bowel infections. The management of bacterial bowel
infections necessitates the implementation of antibacterial therapy. Absolute indications for the initiation of such therapy include infections
like dysentery, amebiasis, typhoid fever, and cholera. Antibiotics should also be used for bacterial ("invasive") ABIs that present with symptoms
of colitis (notably including hemorrhagic colitis), and in severe or systemic instances of the disease, regardless of the patient's age or underlying
conditions. Patients classified as high-risk also require antibiotic intervention regardless of age. Rifaximin has been identified as an effective
therapeutic agent in treating bacterial ABIs, demonstrating efficacy in clinical research. The importance of a balanced method in prescribing
antibacterial therapy, aligned with clinical guidelines, is underscored in the face of escalating antibiotic resistance among pathogens.

Aus Donald Trumps Wiederwahl lassen sich fünf Lehren ziehen, die es zu begreifen gilt: Dass es möglich ist, eine Demokratie demokratisch durch Wahlen abzuschaffen; dass Trump gewählt wurde, nicht obwohl, sondern weil seine Kampagne an die bösartigsten Elemente der amerikanischen Geschichte und Gesellschaft anknüpfte; dass es ihm gelang, Wähler der unteren Klassen mit den Verfechtern eines rücksichtslosen Marktradikalismus zusammenzuspannen; dass dabei die Manipulation von Emotionen eine von der akademischen Linken oft unterschätze Rolle spielte; dass mit der Allianz Trump/Musk Protagonisten einer neuen Stufe kapitalistischer Modernisierung an die Macht gekommen sind.
Vitamin D, Calcium to Magnesium, and the Gut Microbiome
Authors: Chambers Patrick
Published: January 2025

The gut microbiome has been the subject of increasing interest as integral to our health. Few realize that the enormous benefits of vitamin D (VD) and magnesium (Mg) are highly dependent on a healthy gut microbiome. Short chain fatty acids, especially butyrate, reflect not only a healthy gut microbiome but also VD status. Suboptimal VD, Mg, or butyrate translates to some degree of gut dysbiosis and vice versa. Mg dependent secondary bile acids, indoles, and tryptophan, all microbial metabolites and longevity agents, are also discussed. Mg is indispensable to not only the synthesis of the active form of VD but also that of 7-dehydrocholesterol (7-DHC) from acetate. 7-DHC is the substrate for solar conversion to D3. The steadily increasing Ca:Mg in the Western diet and its troubling impact on parathormone (PTH) is discussed. Gut dysbiosis further complicates this. A model addressing the seemingly contradictory reports regarding calcium, magnesium, and VD efficacy among disparate groups is presented. Biochemical and physiologic interlinkages are legion and most remain hidden. This limited mini review exposes insight into the tight linkage between 25(OH) D3 and Ca:Mg, facilitated by the gut microbiome. A model incorporating the physiologically discordant but reinforcing effects on this linkage based on genes, culture, socioeconomic status, and diet is proposed.

Exploring Indonesian Female Viewers’ Identity Projection in Thai BL Series
Authors: Masrina Dwi
Published: January 2025

Thai boys’ love (BL) series portray male-male romance relationship with females as their primary target audiences, though the series tend to avoid depicting women. In the series, both male characters known as seme (dominant) and uke (submissive) possess a mixture of masculine and feminine traits. Using their gaze, women have freedom to choose their gaze’s position weather as seme or uke. This article explores how Indonesian women especially Thai boys’ love series fans, perceive their gender identity when given the freedom to engage with Thai boys’ love series. Through an investigation using qualitative survey, this article shows Thai BL series fans, especially Indonesian females tend to pick their gaze as uke, a male submissive character with more feminine features than the seme one, a male dominant character with more masculine trait. However, there are some fans who stand in seme position. Each preference is caused by two main factors: their own gender and how they behave in their love relationship.

Published: January 2025

The phenomenon of the presence of the effeminate in Yogyakarta has begun to become a common sight. This effeminate community consists of a group of students who have similar preferences and characteristics to the nature and appearance of women. The aim of this research is to provide an overview and information regarding the communication patterns formed by members of the effeminate student community so that they can adapt in the community environment. This research uses qualitative methodology with a phenomenological approach to understand the subjective experiences and perceptions of community members. Data was collected through in-depth interviews and participant observation, then analyzed using qualitative descriptive analysis. The research results show that the effeminate community is divided into 2 levels, namely level 1 and level 2 which have gay sexuality. The process of community communication patterns is different at each level to deal with social stigma and create a safe space for themselves. Communication patterns in effeminate communities involve the use of special language and symbols. Thus, this research provides new information in the form of the composition of communication patterns adopted by the effeminate student community at each level, including their barriers to communication which are influenced by environmental and internal factors.

This research explores the environmental impact of baby formula production and its influence on breastfeeding rates, particularly in Asia. It highlights the role of the Breastfeeding Mother Community on Facebook in raising awareness among mothers, despite a lack of content on the environmental drawbacks of formula milk. The study aims to assess community members’ knowledge of these impacts and its effect on their behavior. Using the TPB theory, it investigates the link between environmental knowledge and perceived behavioral control. The research uses a quantitative approach, using questionnaires, with a sample of 400 respondents from the community. This research employs various data analysis techniques, including descriptive analysis, normality test, simple linear regression analysis, hypothesis testing, and the coefficient of determination test. The findings reveal that the knowledge of the Breastfeeding Mother Community members on Facebook about the environmental impact of formula milk production influences their perceived behavioral control by 28.2%. The remaining percentage is influenced by variables not covered in this research. However, the results indicate no significant influence, as evidenced by the calculated T value being greater than the T table (-4.742 1.965), leading to the rejection of H1 and acceptance of H0.

Published: January 2025

This research aims to understand the parasocial relationship between the virtual community of K-Pop fans and perceptions of presidential candidate Anies Baswedan through the social media platform X. The method used is netnography, which involves observation, downloading, and analyzing uploads on social media. Six procedural netnography movements are applied: initiation, investigation, immersion, interaction, integration, and incarnation. This research uses humanistic phenomenological, existential discourse, hermeneutic interpretation approaches, and thematic interpretation methods to explore themes that emerge from the data inductively. The research results show that parasocial relationships between the K-Pop fan community and Anies Baswedan can be formed and maintained through social media platforms such as @aniesbubble on X/Twitter. This supports the theory that mass and social media are important in forming parasocial relationships without requiring physical meetings. The findings show that interaction through social media content can create strong emotional bonds between fans and public figures. These findings indicate that the fandom phenomenon is not only limited to popular culture, but can also appear in a political context, and that support for Anies Baswedan via social media can impact people's political opinions.

The discussion of self-identity becomes even more unique and interesting when a Muslim Baduy citizen still uses the Baduy identity to show their identity, one of which is through social media. Social media functions as a means for users to place themselves in the framework they want, easily establish relationships, increase insight, form, express and display their identity. Identity is a picture of the cultural, social, relational, and individual self. The purpose of this study is to examine how Muslim Baduy citizens construct their identities on Instagram social media. This study uses a qualitative approach with a case study method. Through data collection techniques through interviews conducted with Muslim Baduy citizens who have used Instagram social media. The results of the study show that the self-identity shown by Muslim Baduy citizens on social media is generally like ordinary citizens. The Baduy identity that is attached to them cannot be easily removed, even though their lives are modern. The existence of social media is used to provide an explanation that they want to be known as Muslims only, no longer called Baduy Mualaf.

A company is developing a strategy for product introduction to a crowded audience. An effective promotional method involves endorsements by prominent figures such as celebrities and community leaders. The company utilizes its service, branded as Shipper, to deliver products. Pair Gram and a currently trending YouTuber serve as endorsers for the product. The endorsers in question are Fiki Naki and Dayana. However, disputes arose between the endorsers, leading to misunderstandings in the digital realm. This conflict resulted in many followers expressing dissatisfaction and unfollowing Dayana's account. The objective of the study is to analyze digital advertising's impact on brand credibility and consumer response to Shipper's products using ethnographic methods. The methodology involves detailed observation of social media data from Instagram, particularly the comment sections on Fiki Naki's endorsement content. The study's findings indicate that the brand credibility associated with Fiki Naki and Dayana received negative feedback from their followers in the comments. Followers perceived the endorsed products as inauthentic, viewing the videos as mere entertainment rather than genuine endorsements. The findings highlight two key concepts, consumer understanding of endorsement activities and the professionalism inherent in endorsement collaborations.

A desk collection agent in an e-commerce platform faces significant challenges in collecting PayLater installments from delinquent customers. This study aims to analyze how professional pressures and communication strategies in desk collection are employed to reduce uncertainty when dealing with PayLater customers who frequently evade their responsibilities. The study utilizes Uncertainty Reduction Theory to examine the psychological pressures and communication strategies used to alleviate uncertainty arising from customer reactions. A qualitative phenomenological approach is applied to collect data on PayLater arrears from the perspective of desk collection agents through in-depth interviews with six informants from three e-commerce platforms. The findings indicate that difficulties in contacting delinquent customers, despite adherence to company regulations and OJK (Financial Services Authority) guidelines, contribute to stress and anxiety due to the potential failure to meet daily targets. However, when desk collection agents employ non-procedural strategies, such as tracking through social media, Google Maps, and posing as field collectors, the success rate increases. Another challenge identified is the interaction with uncooperative customers, which often leads to the use of intimidatory strategies.

In recent decades, there has been an active construction of new buildings in Kazakhstan. The objects being built have a different play of volumes and shapes. Development activity dictates modern trends in the field of architectural and planning solutions of buildings. But not all trends are positive. The purpose of the article is to analyze the risks of the trend of triviality in modern architecture of Kazakhstan, in particular the trend of simplification of spatial solutions of buildings, as well as the influence of the developer on the development of triviality of architecture in general. In addition to the above, the study reflects the conditions and factors influencing the emergence of simple block forms in the volume of the structure of modern architecture in Kazakhstan. The study is based on the analysis of the emergence of triviality in the architecture of the USSR in the middle of the twentieth century, on a full-scale study of the modern architecture of residential buildings in Astana and modeling the formation of a three-dimensional solution of residential complexes. The results show that the process of triviality in the architecture of buildings is caused by the following factors: development activities, aggressive marketing and economic conditions.

The determination of the scope of application of additive technologies by the method of plasma surfacing in the manufacture of aircraft engines is determined by ensuring the mechanical and service properties of heat-resistant nickel and titanium alloys during the production of blanks, necessary for the operation and determination of the technological capabilities of this method. To determine the mechanical properties, 140×70×14 mm heat-resistant nickel alloys ЭП 648ВИ, ВЖ 98ВИ and titanium alloys ВТ6, ВТ20 were grown. After growing, all samples underwent heat treatment according to the technical conditions for each alloy. The mechanical properties for ЭП 648ВИ were determined on these samples (transverse direction: σВ=83.5 kgf/mm2; σ0.2= 63.5 kgf/mm2; δ= 11.2 %; ψ = 21.8 %; longitudinal direction: σB=87.5 kgf/mm2; σ0.2= 57.3 kgf/mm2; δ=21.8 %; ψ= 23.5 %), for ВЖ98 (transverse direction: σВ=83.5 kgf/mm2; σ0.2= 63.5 kgf/mm2; δ= 11.2 %; ψ= 21.8 %, longitudinal direction: σВ=87.5 kgf/mm2; σ0.2= 57.3 kgf/mm2; δ=21.8 %; ψ= 23.5 %), for ВТ6 (transverse direction: σВ=92.2 kgf/mm2 σ0.2= 84.8 kgf/mm2; δ= 17.2 %; ψ= 54.3 %; longitudinal direction: σВ=98.9 кгс/мм2; σ0.2= 91.0 кгс/мм2; δ=9.8 %; ψ= 22.5 %), for ВТ20 (transverse direction: σВ= 115 kgf/mm2; σ0.2= 108 kgf/mm2; δ=15 %; ψ=29.3 %; longitudinal direction: σВ=114 kgf/mm2; σ0.2= 103 kgf/mm2; δ= 14.0 %; ψ=37.6 %). The obtained properties of heat-resistant nickel and titanium alloys are not inferior to blanks obtained by casting and forging methods. The scope of application of additive technologies by the method of plasma surfacing in the manufacture of aircraft engines is defined. For heat-resistant nickel alloys, these are parts included in nozzle devices, heat pipes and combustion chambers. For titanium alloys, these are parts included in the body. From the technological possibilities, the plasma surfacing method is most rationally used when growing cylindrical and conical workpieces of parts with a diameter of 150 to 1500 mm. The technology of adaptive plasma cultivation has been introduced into serial production at JSC "Motor Sich". Currently, more than 20 different types of aircraft engine parts are being produced.
