Authors: Victor Alvianoes Guterez Hose  , Mohammad Saifur Rohman  , Dian Nugrahenny
Published: December 2024

Cardiac fibrosis, marked by excessive collagen accumulation and tissue remodelling, is a key factor in heart dysfunction across various cardiovascular conditions. With limited effective treatments currently available, there is growing interest in exploring natural therapies like green tea and green coffee for their potential antifibrotic properties. Both beverages contain bioactive compounds, such as catechins and caffeic acid, known for their antioxidant, anti-inflammatory, and cardioprotective effects. Green tea has been shown to reduce oxidative stress, lower fibrosis-related markers, and limit collagen deposition in heart tissue. Similarly, caffeic acid from coffee has demonstrated the ability to block fibrosis-driving pathways, such as TGF-β1 signalling, and support cardiac recovery following myocardial infarction. Moreover, the combined use of green tea and decaffeinated green coffee has been found to improve metabolic health by influencing cardiac insulin pathways, which could help mitigate fibrosis in metabolic syndrome models. This review consolidates recent evidence on the mechanisms and benefits of green tea and green coffee in addressing cardiac fibrosis. It highlights their potential as accessible, non-invasive treatment options and underscores the need for further studies to confirm their therapeutic applications in clinical settings.

Published: December 2024

Background: Efforts to manage AAT can be done in several ways, namely by using active and passive methods. For active management is by adding certain chemicals such as lime or alum so that a reaction occurs to control pH and TSS levels. This is related to the actual problems of the research area due to the pH that does not meet the quality standards for coal mining wastewater. The low pH parameters in the research area are a problem in the mining environment, if the content of mining wastewater that has an acidic pH is not neutralized and then directly discharged into the river body causes environmental pollution such as, disruption of aquatic biota that cannot live with an acidic pH and also has an impact on river water which will later be used by the local community for daily activities.
Method: The research methodology is divided into 3 stages, namely: pre-field stage, field stage, and studio or post-field stage. Titration testing on each water sample with quicklime Titration testing to determine the optimum dose using initial measurement data obtained from the field. The dose used starts from 0.1 gr/L to neutral pH according to Environmental Quality Standards. Dosage determination is carried out in the Laboratory owned by PT Antareja Mahada Makmur site Perkasa Inakakerta using a jar test tool. Furthermore, the first data analysis carried out was to analyze rainfall data. From the results of actual flow rate measurements carried out at the inlet of the sedimentation pond and pH measurements in each compartment, the process of determining the amount of efficient quicklime dose for water quality management in the sedimentation pond was carried out.
Results: The initial pH test results averaged 3.86. After the titration test, the final pH averaged 7.45. The results of testing several dose ranges obtained for the initial pH of 3.86 were 0.05 gr/L. Why did the researchers only use one initial pH value because it was the average result of daily measurements carried out for 10 days. To change the optimum dose from a laboratory scale to a field scale is to multiply the optimum dose by the hourly discharge entering the settling pond 81W.
Conclusion : Several efforts have been made by PT Antareja Mahada Makmur, one of which is stabilization using the lime addition method on coal mining wastewater.

An Analysis of Lexical Cohesion Found in "Red" Song Lyrics
Authors: Putirulan Mauren Mauritsya , Cahya Rahmat Adi , Latuihamallo Cindy Itamar
Published: December 2024

This study examines patterns of lexical cohesion in Taylor Swift's song "RED" through systematic discourse analysis. Following Halliday and Hasan's (1976) framework for lexical cohesion, supplemented by contemporary approaches to discourse analysis, we analyzed how various cohesive devices contribute to the song's narrative structure and emotional impact. Our qualitative analysis identified three primary types of lexical cohesion: repetition (56.3%), antonymy (25%), and synonymy (18.7%). The findings demonstrate sophisticated use of repetition patterns, particularly in emotional expressions using gerund forms, creating parallel structures that emphasize emotional progression. The study identifies a complex system of color-based cohesion, with color terms serving both referential and symbolic functions throughout the narrative. Strategic placement of antonymic pairs creates emotional dimensionality, while the use of near-synonymy allows for nuanced emotional expression. These findings contribute to our understanding of how contemporary songwriters use linguistic devices to create emotional impact and maintain narrative coherence. The research advances both theoretical understanding of lexical cohesion and practical insights into effective songwriting techniques, while suggesting new approaches to analyzing popular music lyrics. The study's limitations, including its focus on a single text, suggest directions for future research examining these patterns across a broader corpus of contemporary songwriting.

Authors: Bueno Gessica de Brito , Santos Christian Fausto Moraes dos , Silva Filho Wellington Bernardelli
Published: December 2024

O objetivo do presente artigo é realizar uma análise comparativa entre duas fontes documentais, o Erário Mineral (1735) do cirurgião Luís Gomes Ferreira e “Da natureza da mulher” do físico grego Hipócrates. A intenção é apontar como o uso de elementos e substâncias medicinais do século XVIII, para o tratamento de disfunções uterinas, estava inserido dentro da tradição médica Hipocrático-Galênico. A metodologia utilizada nessa pesquisa é a descritiva e a explicativa. Em nossa conclusão aferimos que a partir da receita da triaga brasílica citada por Ferreira, foi identificado quatro elementos que eram usados para essas disfunções. Ao passo que é situado a semelhança entre o uso deles e as substituições que o cirurgião realiza, na alteração das antigas receitas, devido ao novo contexto e flora disponível no Novo Mundo. Esses elementos são: a arruda, o vinho, a butua e a purga de rom (rum). Por fim, concluímos que médicas portuguesas ainda reproduziam e promoviam a circulação de saberes medicinais para as doenças femininas com base na Teoria Hipocrático-Galênico.
A Química nos primórdios de Belo Horizonte: Sujeitos e Instituições Pioneiras na Capital Mineira
Authors: Silva Rodrigo Régis Campos , Barbosa Luiz Cláudio de Almeida , Filgueiras Carlos Alberto Lombardi
Published: December 2024

Neste artigo são abordadas as primeiras atividades relacionadas ao desenvolvimento de uma Química empírica e suas diversas aplicações nos anos iniciais de Belo Horizonte, mencionando os seus protagonistas e instituições. Buscou-se construir uma compreensão do percurso e desenvolvimento dessas técnicas nos primórdios da cidade, que desde a sua inauguração, em 1897, já detinha o status de capital de Minas Gerais. A análise historiográfica abrange desde os tempos de Curral del Rei, arraial escolhido como a localidade para sediar a nova capital em 1893, até o ano de 1912, quando o químico alemão Alfred Schaeffer se consolidou como a principal referência da Química na cidade, dirigindo o Laboratório de Análises Químicas do Estado. Foram utilizadas as mais variadas fontes para escrever esta trajetória: os relatórios da Comissão de Estudo das Localidades para a Nova Capital e da Comissão Construtora da Nova Capital, relatórios dos primeiros prefeitos, além de anuários, almanaques e periódicos da época. Por meio das análises químicas das águas da localidade, confirmou-se sua qualidade para sediar a futura capital. Nos primeiros anos de uma Belo Horizonte recém-inaugurada, formulações farmacêuticas diversas começaram a ser produzidas, diminuindo a necessidade de importação dos produtos congêneres, o mesmo acontecendo com alimentos e materiais de higiene pessoal. A partir de 1911, com a chegada de Alfred Schaeffer e a montagem de um laboratório com equipamentos trazidos da Alemanha, começaram as análises químicas de diversas amostras, como águas minerais e de abastecimento, leite e minérios.

Authors: Sousa Lia Gomes Pinto de , Lopes Maria Margaret , Bessa Karla Adriana Martins
Published: December 2024

A partir da experiência pioneira de três pesquisadoras do Instituto Oswaldo Cruz, que ingressaram na instituição no início da década de 1960, analisamos o impacto de suas trajetórias na formação de novas gerações de mulheres, atravessando os meados do século XX até a atualidade. O objetivo foi traçar a genealogia intelectual de Monika Barth, Anna Kohn e Delir Corrêa Gomes a fim de complexificar, pelo viés de gênero, nosso entendimento acerca da conformação das ciências biomédicas no Brasil. A investigação se utiliza das ferramentas de busca oferecidas pelas Plataformas Acácia e Lattes/CNPq, juntamente com o cruzamento de fontes arquivísticas e orais, combinando análise quantitativa e qualitativa. As “matriarcas” dessa genealogia inserem-se num contexto histórico em que novos agentes ingressam num cenário em transformação, caracterizado pela expansão de papéis sociais femininos e pelo aprofundamento da institucionalização científica em nosso país. Diplomadas em História Natural, atuaram em temas e técnicas emergentes e contribuíram para a qualificação profissional de quatro gerações de cientistas até os dias atuais, formando uma descendência majoritariamente feminina e multidisciplinar. Conclui-se com a percepção da participação ativa e fundamental de mulheres, ainda pouco visibilizadas em nossa historiografia, no processo de construção, expansão e reprodução institucional da ciência brasileira em diferentes especialidades, no passado e no presente. Por fim, lança questionamentos, a serem aprofundados, acerca das assimetrias e interseccionalidades que atravessam as relações profissionais entre grupos sociais distintos nas diferentes temporalidades.
Políticas ambientais na Nova República: um Ministério de Meio Ambiente no Brasil
Authors: Silveira Jéssica
Published: December 2024

Entre o final da década de 1980 e início da década de 1990 a política brasileira passou por um momento de instabilidade que refletiu na reorganização das políticas ambientais ao mesmo tempo em que foi ampliada a dimensão do debate sobre meio ambiente no Brasil e no mundo, envolvendo diversos setores como a gestão pública, parlamentares e a sociedade civil. Em 1981 foi criada a Política Nacional do Meio Ambiente, que nos seus primeiros dez anos de existência passou por diversas mudanças de caráter político, institucional e organizacional. A construção do Ministério do Meio Ambiente em 1992 se deu em meio a estas negociações, em um cenário de grande atenção mundial sobre a Amazônia no qual os governantes brasileiros buscaram demonstrar que o país se empenhava em construir uma política comprometida com a proteção da floresta. Este texto tem como objetivo discutir a relação entre a construção do Ministério do Meio Ambiente e os múltiplos interesses em torno do esforço pela implementação de acordos internacionais de cooperação em torno das políticas ambientais, sobretudo voltadas para a Amazônia, por intermédio desta primeira versão do Ministério do Meio Ambiente do Brasil.

Desde o final da década de 1980, a História das Ciências se estabeleceu como especialidade no meio acadêmico nacional, alcançando considerável institucionalização, que se constata pela sua inserção em programas strictu sensu da área de História, seja como linha de pesquisa, seja como eixo temático estruturante. Os trabalhos de Maria Amélia Dantes (2001) e Silvia Figueiroa (1997) buscaram pensar a produção científica no Brasil para além das noções de “atraso”, que resultavam de comparações com instituições de pesquisa europeias ou dos Estados Unidos, posicionadas como modelo de excelência. As autoras se alinham às modificações metodológicas nos estudos de História das Ciências ocorridas na década de 1980, que contestavam a perspectiva de que a produção de pesquisa e o cientista dispunham de uma posição isolada do contexto social, político e material de seu tempo (Pestre, 1996).

BIOSTRATIGRAPHIC CHARACTERISTICS OF THE “COSSACK MOUNTAIN” GEOLOGICAL SECTION (KHARKIV AREA): OLIGOCENE, ZMIIV FORMATION. ARTICLE 2
Authors: Shevchenko Tetiana V.
Published: December 2024

The article analyses the peculiarities of the distribution of marine and terrestrial palynomorphs, changes in their composition along the section of the Oligocene Zmiiv Formation of the “Cossack Mountain” (Kharkiv area), which is suggested to be considered as a hypostratotypical section. The differences in the composition of the obtained macerates processed by different methods are described. Technical processing of samples is discussed. The article emphasises the importance of the study of microfacies obtained during palynological studies. The Zmiiv Formation is characterised by a rich complex of organic-walled microplankton (dinoflagellate cysts, green prasinophyte algae, acritarchs). A complex of Wetzeliella gochtii, W. symmetrica, W. articulata, Wetzeliella spp., Rhombodinium draco, Chiropteridium galea, Hystrichokolpoma sp. sensu Zaporozhets, 1998 allows to date it to the late Oligocene. The overlying siltstone sands of the Syvash Formation are characterised by a complex containing Homotryblium. Planktonic green algae (Tasmanites consinnus, Cymatiosphaera, Pediastrum), acritarchs (Ovoidites), remains of terrestrial plants (pollen, spores, plant detritus) are present throughout the “Cossack Mountain” geological section. The presence of foraminiferal fragments and mollusk detritus was noted. Two biostratigraphic units ranked as “beds with dinocysts” are identified in the “Cossack Mount” section: beds with Wetzeliella gochtii, Hystrichokolpoma sp. sensu Zaporozhets, 1998, Rhombodinium draco (Zmiiv sediments) and beds with small Homotryblium (Syvach sediments). Organіс-walled planktonic microfossils correlation between Zmiiv Formation and coeval marine sediments of Northwest Europe and Eastern Paratethys is provided. The article shows the difference between the conclusions on the age of Zmiiv sediments based on marine and terrestrial palynomorphs.

In particular, destroying of the landscape, its degradation as a result of uncontrolled salt karst development, contamination of surface and underground water, threaten the cross-border contamination of the Tisza River. Definition of risks and management decisions to minimize the effects emergency situation should be based on an analysis of its causes. In the article the results of the analysis of geological and exploration activities that accompanied the development of Solotvyno salt dome structure resources; compiled, structured and processed layered multiscale geological information. Hierarchical database has been created and used to develop elements of the Solotvyno structure integrated geological model first iteration (the model of the earth’s surface, structure and tectonic of salt dome, hydrogeological and technological component of the geological environment). Constructions were performed using GIS applications, designed, adapted and improved authors methodic. Solotvyno structure integrated digital geological model has been proposed as a tool for evaluation of geoecological state determination measures to restore equilibrium in the geological environment analysis and evaluation of project technical decisions on the use of salt resources. Analysis of the first iteration model indicates the absence of the modern geological information on the geological environment №t only for ensure the accuracy of model constructions for all Solotvyno salt dome structure, but also to determine the critical parameters of the geological environment. The complex of geological and exploration activities for new geological information and improve the reliability of constructions has been proposed.

Subsurface contamination with petroleum products is a world-scale environmental problem and one of the important directions of geo-ecological activity in Ukraine. This paper describes modern methods of remediation of the geological environment contaminated by petroleum products, their advantages and limitations, possibilities of application depending on hydrogeological conditions of a contaminated site and the purpose of remediation are considered. An example of the application of remediation technologies at the military unit site (Kyiv) contaminated with petroleum products is given. According to the geo-ecological survey of the contaminated area, an increase in the intensity of contamination was established, which can be caused by petroleum product spills and a decrease in the groundwater table, which leads to the release of an additional petroleum product volume. A modern system of subsurface remediation from oil contamination, which includes a set of pumping equipment for the extraction of petroleum products, a system for separating liquids and groundwater treatment, was established and tested.
Attribution of the Sené dynasty seating furniture based on author’s stamps: Experience and challenges
Authors: Bulgakova Alina Viacheslavovna
Published: December 2024

The study aims to determine the authorship of furniture from the ASG Large Collection of Fine Arts based on the analysis of author’s marks of representatives of the Sené dynasty. The study examines 18th-century Parisian ébéniste furniture from state collections, auctions, and galleries. The results of attributing eight Rococo and Neoclassical-era armchairs and two canapés from the ASG collection are presented. The study is novel in that it is the first one to publish photographs of Sené family marks on objects from the collection. The study reveals the SENE mark, which may be a late 19th-century mark. It was determined that nine pieces were made by prominent members of the Sené family, i.e., Claude I and Jean-Baptiste Claude, who worked for King Louis XVI. The furniture is marked with the author’s stamp, corresponding to the reference samples published in monographs by French experts, as well as on the websites of state museums and trade houses. The ébénistes used classic-style stamps with initials. One of the neoclassical canapés from the ASG collection has an unusual stamp without the master’s initials. Determining the author of this canape is difficult today, as three masters of the Sené family worked in the style of Louis XVI’s reign, and there is limited comparative material. During our research, we found only one set of furniture with a similar stamp, currently located in France in the gallery Antiquités Philippe Glédel. Experts consider this stamp to be apocryphal and doubt its authenticity.

The purpose of the research is to comprehend the metamorphoses of the symbol image of Babylon and the winged expression "Tower of Babel" in M. Gorky's epic novel "The Life of Klim Samgin". The article examines the metamorphoses of images of Babylon and the Tower of Babel in the context of the narrative, analyzes associations, interpretations of the "Babylonian microtext" in the complex figurative system of the novel. The scientific novelty of the study lies in the fact that for the first time it interprets the meanings of the inclusion of the biblical expression "The Tower of Babel" in the novel "The Life of Klim Samgin", taking into account the results of the latest literary works of the 21st century devoted to the biblical text, in the light of the leitmotif "the sacrifice of Abraham" (E. R. Matevosyan). As a result of the research, it was found that in the context of the events, the writer used the catch phrase "Tower of Babel" in the episode "destruction of the artillery barracks" to translate the narrative into a "utopian discourse." In the socio-cultural situation depicted by the author at the turn of the 19th and 20th centuries, the symbol "Tower of Babel" reveals its meanings in contact with the theories of the Social Democrats (Kutuzov and his like-minded Marxists) who replaced the narodniks. The reader gets the meaning of this popular expression as the illusory nature of humanity's "utopian projects" and can predict the outcome of the plot, anticipating the logic of its development and the logic of the actions of the characters associated with the "Babylonian text".
Principles of andragogy in the aspect of teaching Russian as a foreign language in intensive training courses
Authors: Kolomeytseva Ekaterina Borisovna , Matveev Andrei Pavlovich
Published: December 2024

The article is devoted to the principles of andragogy as a developing part of general pedagogy in the context of teaching Russian as a foreign language (RFL). The purpose of the study is to determine the principles of andragogy that are most applicable in teaching RFL and to develop an effective lesson structure based on them. In the article, the authors compare the principles of teaching, select effective methods of working with adult learners in RFL lessons. The focus is on aspect-based teaching in intensive training courses for adult students, so the authors elaborate on the lesson plan, which is based on the principles of andragogy, and provide recommendations on aspect-based work with adult learners. Until now, the principles of andragogy have been considered as a whole in application to teaching foreign languages, including Russian linguistics, but the andragogical methods of work in aspect teaching have not been traced. Thus, the scientific novelty lies in the identification of effective andragogical techniques in the aspect teaching of RFL. As a result of the analysis of the andragogical concepts and principles of RFL teaching, the authors identify the most relevant teaching methods and develop an example of a practical lesson based on the principles of andragogical teaching.
Bilingualism and code-switching in the Moldovan variant of the Romanian language: The impact of the Russian language on the formation of ethno-linguistic identity of Moldovans
Authors: Malysheva Elizaveta Yurievna
Published: December 2024

The purpose of the study is to systematize the characteristic linguistic markers of bilingualism and code-switching that were formed under the influence of the Russian language in the Moldovan version of the Romanian language, as well as to determine their role in shaping the ethnolinguistic identity of Moldovans. The scientific novelty of the work lies in the identification of patterns and mechanisms of adaptation of Russian-speaking elements that form a new linguistic space in which Romanian and Russian linguistic units coexist, creating specific lexico-semantic and syntactic models. The article summarizes the historical, social and cultural prerequisites of centuries-old language contacts, leading to the integration of Russianisms, syntactic calculus and interlanguage interference. As a result of the study, it was found that bilingualism and code-switching not only expand the lexical and pragmatic range of the Moldovan version of the Romanian language, but also function as markers of the ethnolinguistic identity of Moldovans. They reflect the regional identity and cultural and historical specifics of the society living in a certain territory, contribute to strengthening group solidarity and differentiation from other Romanian-speaking regions.
