Introduction. Therapy of patients with acute ST-elevation myocardial infarction and massive coronary thrombosis (TTG 3) is a far from solved problem of modern medicine, since often in such patients immediate stent implantation is associated with the development of myocardial hypoperfusion, reducing the long-term prognosis of life.

Aim. To evaluate short-term and long-term efficacy and safety of delayed and immediate coronary artery stenting techniques in patients with acute ST-elevation myocardial infarction and massive coronary thrombosis.

Material and methods. Comparative study in parallel groups, a total of 153 patients with ST-elevation myocardial infarction and massive coronary thrombosis (TTG 3), 75 patients in the delayed coronary artery stenting group, 78 patients in the immediate coronary artery stenting group. In the immediate coronary artery stenting group, percutaneous coronary intervention was performed in one stage with stent implantation, in the delayed coronary artery stenting group; percutaneous coronary intervention was performed in two stages: the first was achieving TIMI-3 blood flow using a minimally invasive mechanical strategy, the second was control coronary angiography 5-6 days and the decision on the implantation of the stent. The primary endpoint is: the rate of achieving optimal myocardial perfusion according to angiography, the secondary combined endpoint is the rate of major adverse cardiovascular events.

Results. In the hospital period, optimal reperfusion (TIMI-3 and MBG 2-3) after the primary procedure was achieved in 88% in the delayed coronary artery stenting group and 69.2% of immediate coronary artery stenting with an advantage in the delayed coronary artery stenting group (p=0.005). Of the 75 patients in the delayed coronary artery stenting group, 38 patients (51%) did not receive a stent in the delayed period due to the insignificance of stenosis on the control coronary angiography. There was no significant difference in the incidence of major adverse cardiovascular events between the groups. In the long-term period, the median follow-up period was 47 months. The frequency of major adverse cardiovascular events was 13.3% in the delayed coronary artery stenting group and 23.1% in the immediate coronary artery stenting group, with a trend towards the advantage in the delayed coronary artery stenting group (p=0.1). Overall mortality (9.3% vs. 11.7%), recurrent myocardial infarction (2.6% vs. 5.1%), target vessel revascularization rate (1.3% vs. 6.4%) were without significant benefit. between subgroups.

Conclusion. In patients with ST-elevation myocardial infarction and massive coronary thrombosis, the use of delayed coronary artery stenting gives an advantage in achieving myocardial perfusion after the procedure, and demonstrates a tendency to reduce adverse cardiovascular events in the long-term period.
Condition of the problem of organ transplantation in the USSR in 1970–1971 and ways to solve it (Yu.M. Lopukhin, A.G. Lapchinsky, V.P. Demikhov)
Authors: Glyantsev S. P.
Published: December 2023

Aim. The article examines and analyzes the state of the problem of organ transplantation in the USSR in the early 1970s and ways to solve it with the participation of three prominent transplantologists of the Soviet Union – Yu.M. Lopukhin, A.G. Lapchinsky and V.P. Demikhov, as well as some world achievements in this field.

Material and methods. Available printed works on the history of Russian and world transplantology in the 1970s, the analysis of which was carried out by historical-genetic and comparative-analytical methods.

Results. Developed by Yu.M. Lopukhin together with leading surgeons and immunologists of the country the Program of scientific research on the problem of transplantation of organs and tissues included three main areas: clinical problems of transplantation of organs and body parts (limbs), including ensuring the viability of organs and tissues outside the body, the ways to overcome biological incompatibility, and also the moral and ethical issues of transplantation, and donation issues. It is shown that the methods of overcoming biological incompatibility in organ and tissue allotransplantations, which had been used for many years by A.G. Lapchinsky and V.P. Demikhov (exchange transfusion of blood between organisms of different species, cross circulation between individuals of the same species), no longer corresponded to the state of medical science, which was represented by Yu.M. Lopukhin. However, scientists who had world-class priorities for the duration of survival of experimental animals with a transplanted limb (A.G. Lapchinsky) and an additional heart and lung transplanted into the chest (V.P. Demikhov) could help in the implementation of some provisions of the Lopukhin’s Program. The preservation of organs and tissues before transplantation in a state of suspended animation was studied by A.G. Lapchinsky, and V.P. Demikhov worked at developing the methods for the extracorporeal connection of organs to the body of an intermediate host and using portable artificial hearts to maintain the vital activity of a cadaveric heart before transplantation.

Conclusions. Pioneers of experimental transplantology in the USSR A.G. Lapchinsky and V.P. Demikhov, who began their research in the 1940s, still could have solved many issues of transplanting organs and body parts by the 1970s. But in presented in 1971 Program on the problem of organ and tissue transplantation, prepared under the guidance of Yu.M. Lopukhin, the emphasis was placed on immunological studies, while experimental surgeons played a minor role in it.

Published: December 2023

Este artigo caracteriza-se por ser um estudo bibliográfico, amparado no método Materialista Histórico Dialético elaborado por Marx, nas formulações de Vygotsky e na Teoria Histórico Cultural. Tem como objetivo analisar as dificuldades do acesso à educação escolar para a classe trabalhadora durante a pandemia do Coronavírus, bem como, demonstrar as impressões resultantes dessa análise. Com vistas a alcançar o objetivo proposto, o trabalho, está organizado em duas partes: Inicialmente, buscamos entender como é o acesso à educação escolar e a aquisição de conhecimentos na sociedade capitalista. Posteriormente analisamos sobre como têm sido a educação escolar para crianças e jovens de classe trabalhadora durante a pandemia. Na sociedade capitalista, onde o acesso aos conhecimentos escolares são fragmentado para a maioria das pessoas, durante a pandemia, com o fechamento das escolas públicas para conter a disseminação do vírus da Covid-19, muitas crianças e jovens de classe trabalhadora não tiveram acesso a muitos conhecimentos escolares, pois a maioria das famílias tiveram limitações econômicas o que influenciou na aquisição de equipamentos eletrônicos e pacotes de internet para acessar as aulas que passaram a ser realizadas remotamente. Fatores que limitaram a aprendizagem e o desenvolvimento dos estudantes da classe trabalhadora, assim como, a interação social. Ante ao exposto, percebemos a importância da educação escolar pública realizada de maneira presencial, na garantia da aquisição dos conhecimentos básicos, visto que o acesso à educação pública é um direito e, apresenta-se aos trabalhadores como possibilidade de formação crítica.
Autodefinição, consciência política e ética social:
Authors: Almeida Ceila Sales de
Published: December 2023

As mulheres negras, dentro do processo de epistemicídio colonial, foram excluídas e invisibilizadas, enquanto produtoras de epistemologias e saberes, especialmente, no universo acadêmica-científico. Mas, mesmo diante das opressões interseccionais impostas pelas ideologias racistas e patriarcais, elas construíram um pensamento específico, coletivo, político, voltado a superação das negações de direitos e opressões, a partir da autodefinição e empoderamento coletivo. No Brasil, o pensamento feminista negro atuou, desde o início da dominação colonial, construindo resistências, teorias e lutas. A partir desse contexto, o presente artigo tem como problema principal analisar as categorias do pensamento feminista negro, autodefinição e empoderamento, a partir do legado intelectual e ativismos de Lélia Gonzales. Como objetivo específicos, aborda o pensamento feminista negro, as categorias analíticas teóricas de autodefinição e empoderamento, e seus reflexos na trajetória do feminismo negro no Brasil, e por fim, a trajetória de vida e pensamento de Lélia Gonzales. A metodologia utilizada é a pesquisa bibliográfica qualitativa, afrorreferenciada. Trata-se de um tema com relevância teórica e social, uma vez que, apresenta um pensamento acadêmico-científico em um viés decolonial, bem como, fundamentos para a construção de práticas antirracistas e antissexistas.
Injustiças epistêmicas

Published: December 2023

Partindo de uma abordagem indutiva sustentada na metodologia de histórias de vida inspirada na Escola de Chicago e no seu uso de métodos antropológicos para estudar populações urbanas, com particular destaque para Robert Park e Ernest W. Burgess e potenciadas no contexto académico português por Elsa Lechner, este artigo apresenta uma reflexão crítica sobre injustiças epistêmicas e formas de lutar contra estas no cotidiano das mulheres afrodescendentes da área metropolitana de Lisboa. Para tanto, o artigo está organizado em três partes complementares: na primeira, será apresentada uma conceituação introdutória de injustiça epistêmica a partir de várias perspectivas teóricas feministas e descoloniais. A segunda parte explora três eixos de análise relevantes para a desvalorização do conhecimento produzido pela diáspora feminina negra. A terceira parte, usando estudos de caso baseados nas histórias de vida das mulheres afrodescendentes em Portugal, oferece exemplos concretos de estratégias de resistência epistemológica e política contra os efeitos adversos da injustiça epistêmica, particularmente no que diz respeito à questão racial e sexual. Em suas observações finais, a pesquisa conclui que a injustiça epistêmica condiciona a formação de processos de subjetividade. Apesar disso, as vozes de grupos estruturalmente racializados e discriminados, como o caso das mulheres afrodescendentes, podem ser potenciadas por meio de práticas de resistência política por elas desenvolvidas. Essas práticas permitem que essas mulheres se reapropriem de suas vidas e da liberdade de se definir a si mesmas.
Desafios latinoamericanos e as esperanças do bem viver
Authors: Fernandes Bruno , Peres Isabela Kojin , Benetton Lorena Gebara
Published: December 2023

Crises múltiplas e interligadas marcam os tempos atuais, colocando em xeque o projeto da modernidade, tornando cada vez mais urgente realizar o que Boaventura de Sousa Santos chama de transição paradigmática que é tanto epistemológica quanto societal. O Bem Viver que é uma perspectiva ancestral dos povos originários, tem despontado na América Latina como uma alternativa sistêmica capaz de inspirar a construção de outros mundos possíveis. Entre os desafios para sua realização estão o modelo desenvolvimentista extrativista, a racionalidade instrumental e a concentração de poder que são fruto da colonialidade que se perpetua até hoje. O risco é que o Bem viver, assim como outras propostas, seja cooptado e desvirtuado pelo projeto da modernidade. Por isso, é preciso determinar sobre qual Bem Viver se está falando e quais suas características fundamentais, ainda que não exista um único caminho. A partir de uma perspectiva multirreferencial e da análise crítica de experiências que já estão sendo realizadas em outros campos, o presente ensaio propõe três pontos considerados estruturantes para o Bem Viver: i) uma nova racionalidade ambiental com base na ecologia de saberes, como “amefricanidade”, ii) um sistema econômico e produtivo não extrativista/pós-extrativista, e iii) modelos organizativos descentralizados territorialmente.
Jogos lúdicos

Published: December 2023

Os estigmas enfrentados pelos familiares dos encarcerados podem ser considerados graves problemas atuais. Neste contexto, as crianças são as mais vulneráveis, pois dependem emocional e economicamente de seus pais. As crianças, cujos pais estão aprisionados, vivenciam uma variedade de consequências negativas, principalmente em termos de sua saúde emocional e de seu bem-estar. Portanto, trabalhar com um grupo de crianças estigmatizadas devido ao aprisionamento de um de seus pais ou de ambos e buscar novas alternativas para a melhoria da capacidade de resiliência e autoestima dos filhos dos apenados foi o estímulo para este trabalho. Para tanto, foram utilizados os conhecimentos e métodos do Design de Inovações Sociais como alternativa para a solução desse complexo desafio. Assim, o objetivo foi desenvolver oficinas de jogos, brinquedos e brincadeiras lúdicas, utilizá-las junto aos filhos de encarcerados e avaliar seu desempenho. Tratou-se de uma pesquisa de cunho quanti-qualitativa que envolveu, através da pesquisa de campo, um grupo de crianças cujos pais estavam encarcerados na Associação de Proteção e Assistência aos Condenados (APAC) na cidade de Itaúna-MG/Brasil. Constatou-se que a aplicação dessas oficinas lúdicas se apresentou positivamente como uma “solução inovadora” tanto para o acolhimento e a assistência às crianças filhas e filhos dos apenados bem como para seus pais e mães. Entendeu-se que tais oficinas não são por si só a única solução ou a solução perfeita, mas que foram adequadas para: criar um espaço descontraído e mais agradável dentro do presídio para as crianças frequentadoras daquele árido espaço.

Published: December 2023

O artigo investiga traços dissonantes presentes em Instruções Normativas dedicadas a gerir os procedimentos do PRONAC, editadas pelo Executivo federal no período pós-impeachment, que impactou fortemente na condução da gestão federal de cultura. Foram mobilizados um acervo de fontes comunicacionais, como discursos públicos, reportagens e mensagens em redes sociais e documentos jurídico-político, principalmente os instrumentos infralegais, que tiveram o uso intensificado para superar “barreiras” de disputas legislativas. Apontamos também contradições entre a performance discursiva e a formulação das normas, sobretudo na última Instrução analisada, de 2022.
Como pesquisadores em avaliação de impactos e licenciamento ambiental analisam a participação da sociedade afetada nos empreendimentos sujeitos ao estudo de impacto ambiental no Brasil?
Authors: Pizella Denise Gallo , Santim Jaqueline Bruna
Published: December 2023

O artigo teve como objetivo investigar a percepção de pesquisadores da área de Avaliação de Impactos Ambientais sobre como os processos de participação da sociedade se encontram no Brasil. A metodologia consistiu no envio de questionários ao público alvo, além da revisão da literatura sobre o tema. Como principais resultados, os participantes da pesquisa consideraram que a participação da sociedade é possibilitada em momentos tardios das tomadas de decisão sobre empreendimentos licenciados com Estudos de Impactos Ambientais, por meio de audiências públicas que não propiciam a intervenção social de todas as partes interessadas. Deste modo, indicaram uma abertura de canais participativos em diversos momentos do licenciamento ambiental destes empreendimentos, de modo a propiciar que a sociedade civil afetada ou interessada traga seus anseios e demandas ao longo do processo, tanto na elaboração do estudo ambiental e no acompanhamento das eventuais licenças concedidas.
Por uma Intelectualidade Afrodiásporica
Authors: Pereira Rosana da Silva
Published: December 2023

Neste artigo apresento reflexões sobre os atravessamentos da produção intelectual de mulheres negras e do feminismo negro brasileiro. Tendo a emancipação como ponto crucial para mudanças na teoria crítica social, inicialmente destaco contribuições epistemológicas acerca do pensamento feminista negro em uma perspectiva transnacional, compreendendo-as como importantes para a sustentação de uma teoria social insurgente. Para fomentar a discussão sobre a intelectualidade de mulheres negras atravessadas pelo feminismo negro trazemos a luz as contribuições de intelectuais negras estadunidenses e brasileiras. Por fim, destacamos a caracterização do que chamo de epistemologias emancipatórias em convergência com a crítica à política de centralização do conhecimento e apagamento da memória.
O silenciamento da Beata Maria de Araújo na construção de sentidos em torno do milagre da hóstia em Juazeiro do Norte - CE
Authors: Torres Geovane Gesteira Sales , Oliveira Bárbara Almeida , Leite Maria Laís dos Santos
Published: December 2023

Este trabalho tem como tema a construção de sentidos conferidos à Beata Maria de Araújo na atualidade, em virtude do seu protagonismo no “milagre da hóstia” em Juazeiro do Norte-CE, no ano de 1889. Objetiva-se analisar as práticas discursivas expressas em leis e notícias jornalísticas acerca da Beata Maria de Araújo no contexto atual de Juazeiro do Norte-CE; e identificar de que modo os marcadores sociais da diferença operaram para o apagamento dessa personagem na memória e historiografia do território. Para essa finalidade, adota-se uma revisão narrativa da literatura pertinente ao campo de estudos da história social, além de análises em documentos de domínio público (legislações municipais e estaduais, além de textos jornalísticos) concernentes à religiosa. Os dados revelam que embora sejam consideráveis os avanços históricos em torno da edificação de uma memória social que reconheça o protagonismo da religiosa na construção histórica e mística de Juazeiro do Norte, os locais simbólicos ocupados por ela ainda estão em planos secundários. Isso é um produto histórico advindo da atuação de agentes como a Igreja Católica que silenciou, em vida e após a morte, a religiosa em questão. Entende-se que isso se deu, especialmente, pelo cruzamento de opressões vivenciadas pela beata em virtude dos marcadores sociais da diferença gênero, raça e classe.

Práticas socioambientais na produção sustentável da Associação das Mulheres Extrativistas Sementes Araguari (Amapá)
Authors: Costa Célia Souza da
Published: December 2023

Este artigo discorre sobre os objetivos do desenvolvimento sustentável em consonância com a prática da produção sustentável das mulheres extrativistas do rio Araguari. Elas são conhecidas como sementeiras do Araguari e produzem biocosméticos a partir da andiroba, copaíba, pracaxi e de outras sementes que são coletadas na Floresta Nacional do Amapá (FLONA) que também é uma Floresta Estadual (FLOTA). Esse território está localizado no estado do Amapá. Os biocosméticos produzidos são pomadas, velas e sabonetes que geram renda para cerca de 80 mulheres extrativistas e suas famílias. Antes, as mulheres e suas famílias tinham como a única alternativa de renda o trabalho ilegal em um garimpo que foi fechado em 2007. Os objetivos deste artigo é discutir como as mulheres extrativistas conseguem por meio da produção sustentável atingir os objetivos do desenvolvimento sustentável e analisar as práticas socioambientais realizadas por essas mulheres. O método utilizado é a pesquisa qualitativa com a abordagem exploratória.  Os resultados apontam que há uma preocupação das famílias que são lideradas por essas mulheres extrativistas em garantir uma melhoria de qualidade de vida com o proveito dos recursos naturais por meio da produção sustentável que gera fonte de renda ao mesmo tempo que cuida da floresta e todos os seres que habitam nela.
desnudamento como busca da cura na escrita do presente de Pedro Juan Gutiérrez
Authors: Mendes Daniel
Published: December 2023

Neste artigo buscamos analisar a obra Trilogia suja de Havana (1998), do escritor cubano Pedro Juan Gutiérrez (1950-), a partir da noção narrativa de “desnudamento” como busca da cura pelo autor-narrador-personagem. A referida obra é concebida aqui como uma escrita do presente, que dialoga com uma série de outras categorias referentes à literatura contemporânea, dentre as quais: escrita do eu e dos outros, escrita autobiográfica, autoficção, escrita do trauma e escrita terapêutica, literatura de testemunho, entre outras. Ao adotarmos outras proposições crítico-teóricas para uma releitura sobre esta obra, objetivamos com isso a ruptura com leituras hegemônicas distanciadas que a lograram ao exotismo – logo, trata-se aqui de uma releitura anti-exótica; fundamentando, dessa forma, chaves de leituras analíticas mais pertinentes para uma compreensão qualificada sobre a mesma. Dentre os resultados obtidos mais relevantes, evidenciamos a trilogia de Gutiérrez como vinculada ao “pacto ambíguo” por situar-se justamente nos interstícios narrativos entre o chamado romance moderno (ficção) e a autobiografia (realidade).

SERIES TERMINATION OF SINGLE-ENDED LVCMOS SIGNALS
Authors:   Lviv Politecnic National University, Seheda Oleh , Nazarkevych Ihor ,   Lviv Politecnic National University
Published: December 2023

For synchronous signals with fast edges traces on printed circuit boards are transmission lines, not just conductor connections. If the length of the PCB trace exceeds certain values, it is necessary to match its impedance with the signal source and/or receiver. Impedance mismatches would bring signal reflections from the source to the receiver and back through the trans- mission line. Such reflection or distortion of the signal is called "echo" or "ringing". It is shown in emissions and irregularities of the waveform, especially the rise and fall edge. In this article, practical guidelines for sequential termination of one-way signals are considered that would resolve such effects. The simulations were done for LVCMOS signals [1].

The rotor is a key element of high-speed mechanisms that are widely used in various industries, such as laboratory centrifuges used to separate mixtures of different fractions, gas turbines, industrial compressors, engines, and others. The main requirement for such mechanisms is reliability and safety during operation. To ensure the above requirements, it is necessary to determine the stress-strain state of the most loaded structural elements of the system and the dynamic characteristics. This paper presents an analysis of the stress-strain state of a rotor system using the example of a Pico21 laboratory centrifuge. The Ansys and KISSsoft software packages were used for 3D modelling of the finite element model. The system consists of a flexible shaft with a rotor, the rotor mass was changed during the simulation and supports, the role of which is performed by bearings. A comparative analysis of the obtained results of the stress-strain state is presented, which further makes it possible to carry out appropriate calculations taking into account stress concentrators to determine the durability and lifetime of high-speed mechanisms. The stresses are determined according to the von Mises and Tresca criteria. The paper also presents the results of the calculation and analyses the natural frequencies of the rotor system. Further studies, it is planned to determine the natural frequencies of vibration, taking into account gyroscopic effects, which are necessary to determine the resonant frequencies and zones of stable operation of the system.

Published: December 2023

Energy-efficient technologies are an important aspect of the development of mechanical engineering. Therefore, the creation of highly efficient vibration technological equipment is an urgent task. There are discrete-continuous inter-resonance vibration machines that have high values of dynamic amplification of oscillations. Rectangular plates or rods are used as the reactive mass of such vibrating machines. However, the rectangular shape of the plate may not be the optimal shape for achieving maximum energy efficiency. To conduct experimental studies of alternative plates with a variable cross-section to determine the optimal shape of the reactive mass of the vibration machine. Methodology. The selection of alternative options of plates with a variable cross-section, which would satisfy the necessary conditions of fastening and the value of the natural frequency of oscillations, was carried out. Experimental studies were carried out on a sample of an inter-resonance vibrating table. The value of the power supply voltage at which loads of different masses were separated from the working body of the vibrating table for each of the plate samples was compared. Findings (results) and originality (novelty). For the first time, experimental studies of the energy efficiency of inter-resonance vibration machines with plates with a variable cross-section installed as a reactive mass were conducted. It was found that the rhomboid shape of the plate is optimal when using it as a continuous section in a vibration machine with an electromagnetic drive. It was determined that the use of diamond-shaped plates as the reactive mass of the vibrating machine can improve the energy efficiency of the inter-resonance vibrating equipment. For further analysis of plates with a variable cross-section as a reactive mass of an inter-resonance vibration machine, it is necessary to calculate and compare their lumped inertia-stiffness parameters.

The results of modelling and investigation of external and internal gear-cutting processes using the power skiving method are presented. The principles of constructing a geometric model of undistorted chip formation are described, based on parameters from which cutting forces are calculated. It is found that, under identical conditions, the cutting force is three times greater when internal gears are cut than when external gears are cut. The influence of this force on the machining error is determined by the gear pitch parameter. It is shown that the most rational way to reduce the machining error is to reduce the cutting force by reducing the axial feed rather than by increasing the number of passes.
OPTIMIZATION OF OLIGONUCLEOTIDES CHARACTERISTICS WITH TOPSIS
Authors:   Department of Chemistry and Biochemistry, Department of Physics, Concordia University, Javanbakht Taraneh
Published: December 2023

This paper focused on a new application of the TOPSIS method for the prediction and optimization of the oligonucleotides characteristics. This method has been used for these purposes as it has shown its efficacy for these analyses. This is the first time that it has been applied to the investigation of these biomolecules. The hypothesis in this paper was that the characteristics of these biomaterials would be optimized according to their structural differences. The obtained results showed that the stabilization of oligonucleotides would affect their ranking with TOPSIS when the stability of these biomolecules increased against enzymes in their structure. In other words, the oligonucleotides with less enzymatic degradation were ranked better with this method. This study showed the first application of this algorithm for the prediction and optimization of the oligonucleotides’ characteristics. The results in this work revealed that the ranks of candidates depended on their distances from their ideal solutions. This showed that TOPSIS could be used as an appropriate method in the optimization of oligonucleotides as the rankings with this method would coincide with the data that concern the stability of these biomolecules against enzymatic degradation. The results of this work could be applied for the preparation of novel materials with applications in science and engineering.

Crack growth resistance of ZrO2-(3-8) mol% Y2O3 ceramics was investigated. Young's modulus by the ultrasonic flaw detection method were determined. Vickers hardness and parameters of cracks after Vickers indentation were obtained. Based on the Young's modulus values, Vickers hardness, and parameters of cracks, the fracture toughness of the investigated ceramics was calculated using 9 different equations of the Vickers indentation method. A comparative analysis of the calculated fracture toughness values with those obtained by the single-edge notch beam method was carried out. It was found that choosing the optimal equation for calculating fracture toughness by the Vickers indentation method is quite difficult and requires comparison with the results of standardized tests. It was shown that to determine crack resistance characteristics of the yttria-stabilized zirconia ceramics, the use of only the Vickers indentation method without comparison with other methods of fracture mechanics is incorrect.

Evaluating the effects of wilting, mixing with timothy and silage additive application on red clover silage quality
Authors: Rinne Marketta , Franco Marcia , Manni Katariina , Huuskonen Arto
Published: December 2023

Red clover is typically produced as a mixed stand with grasses, which may lead to suboptimal fertilization and harvest time practices, resulting in poor survival of red clover. Further, unknown proportions of red clover in mixed swards complicate ration formulation for livestock. Thus, producing red clover as pure stands could offer benefits, but it may be difficult to ensile. The objective of the current study was to evaluate major management possibilities such as wilting, inclusion of timothy grass and different types of additives in optimizing the ensilage of red clover. Low DM silages were poorly preserved with high pH, elevated acetic acid concentrations and proportions of ammonia-N in total N, as well as depleted water-soluble carbohydrate levels. Moderate wilting clearly improved the fermentation quality of silages. Further, the use of formic acid-based additives improved the fermentation quality of the silages, the effect being more pronounced in the low than medium dry matter silages. The composition of red clover and timothy were rather similar regarding dry matter content and ensilability. This was probably the reason why clear benefits in silage quality from timothy inclusion could not be demonstrated.

Introduction. An expanding number of indications for PCI in patients with coronary heart disease and severe concomitant pathology are accompanied by a growing number of patients with chronic renal failure. Contrast-induced nephropathy (CIN) is recognized as a severe complication, aggravating the course of the underlying disease, and, moreover, reducing the life expectancy of the patients. Modern intravascular imaging technologies are widely implemented in real clinical practice of endovascular surgery. In the context of increasing number of PCI performed in patients with severe concomitant pathology, the IVUS-guidance will improve the quality of stenting, and, importantly, lessen the risks of CIN due to the reduction in contrast volume. Materials and methods. The paper presents a clinical case of IVUSguided stenting of the right coronary artery without contrast agent in a patient with chronic kidney disease and the following diagnosis: “Coronary heart disease. Effort angina, class III (dyspnea as anginal equivalent). Balloon angioplasty and stenting of circumflex artery and LAD. Hyperlipidemia 2a. Atherosclerosis of the aorta, brachiocephalic and coronary arteries. Stage 3 hypertension. Controlled Hypertension. Level IV CVD risk. Type 2 diabetes mellitus. Target glycated hemoglobin is less than 7.5%. Grade 2 obesity, exogenous-constitutional. Renal microlithiasis. CKD stage 4 (GFR 29 ml/min/1.73m2). Cerebrovascular disease. Chronic cerebral ischemia.” Results and discussion. In the described clinical case, a complete myocardial revascularization was achieved using IVUS-guidance and minimal amount of contrast agent in a patient with severe CKD. The advantage of minimally invasive endovascular interventions in a complex category of patients, demonstrated by the case, implies expanded possibilities for providing high-tech care to patients with significant limitations in the use of contrast agents due to severe CKD with a high risk of CIN. Conclusion. Today, an increasing number of X-ray operating rooms in Russia are equipped with intravascular technologies, ensuring their wider use. The skills and knowledge in using IVUS imply rare application of contrast agents, thereby lessening the risk of CKD and, as a consequence, improving the prognosis of patients with reduced renal function and high risk of CKD.
Effect of Remittances on Renewable Energy Consumption in India: Evidence from a Nonlinear Analysis
Authors: Chakraborty Debasis
Published: December 2023

The flow of remittances is decisive in shaping India's economic and societal welfare. India is also one of the fastest-growing economies, and its energy demand has a determining impact on global energy consumption. Remittances are often seen as a crucial source of external finance for India and can play a decisive role in financing renewable energy generation projects. However, minimal exploration has been conducted on the issue of interrelationship between remittances and renewable energy consumption in India. The present study attempts to empirically test the impact of remittances on the level of consumption of renewable energy in India over the period 1990–2020, which, to the best of our knowledge, none of the previous studies has dealt with yet. The results of the nonlinear autoregressive distributed lag (NARDL) model show that a lagged negative shock of remittances positively and significantly impacts renewable energy consumption in India. The long-term result confirms that a negative shock of remittances significantly reduces renewable energy use. The reduction of remittances has a more significant impact than the increase of the same, implying the existence of an asymmetric impact of remittances over renewable energy consumption. One of the critical policy implications of these findings is that the government should promote policies that enhance the inflow of remittances as it would facilitate the use of renewable energy in India.

As a country with Muslim majority population, Indonesia is a potential market for the development of the Muslim fashion industry. However, this opportunity has not been utilized optimally due to the limited ability to understand customer needs and desires and the lack of Islamic small-business fashion knowledge in determining strategies that can be used to improve Marketing Performance (MP). Thus, this study aims to improve marketing performance in Islamic small business fashion by increasing marketing capability. Three dimensions of marketing capability were used in this study, namely marketing innovativeness (MI), market sensing capabilities (MSC), and Customer Relationship Management Capabilities (CRMC). Previous studies have shown that there are inconsistencies in findings that examine the relationship between marketing capability and marketing performance. Theoretically, marketing capability is a strategic tool for improving marketing performance, but practically the marketing capability dimensions do not always produce better marketing performance. Therefore, this study proposes a Religio-Centric Marketing Communication Strategy (RMCS) as a variable that mediates the relationship between marketing capability and marketing performance. RMCS is a new variable that was formed from the collaboration between marketing communication strategy and religio-centric concepts. RMCS is a marketing communication strategy that is carried out religiously when communicating with other parties. The population in this study are owners or managers of Islamic small business fashion in Indonesia. Data were obtained from questionnaires distributed to 310 selected respondents and then analysed by using Structural Equation Model (SEM) with AMOS. The results showed that MP can be increased through MSC, CRMC, and RMCS, but MI was apparently unable to increase MP. Meanwhile, optimizing RMCS can be done through MI, MSC, and CRMC. From these results, it can be concluded that the performance of Islamic small business fashion can be improved through marketing communication strategies in a religious manner when communicating with other parties.

Investors are integrating ESG factors into their decision-making processes in order to invest sustainably and gain competitive returns. The presence of risks from the recent past and the near future, as well as the occurrence of a rare, unforeseeable, and economically significant event known as a black swan event, hinder their ability to make sound investment decisions. In light of this matter, our study aims to develop a conceptual framework for the risk-return issue in ESG investments. The Southeast Asia region will be emphasised more due to its potential for future ESG investment growth and higher returns. Consequently, our investigation provides two possible frameworks to measure the relationship between ESG risks and ESG firms' stock returns in Southeast Asia. In the absence of ESG indices in the region, local ESG companies listed on stock markets have been suggested as a viable alternative.

Despite the rise of influencer marketing in creating brand engagement with customers on social media platforms, there exists limited understanding about the factors that contribute to brand engagement in self-concept (BESC) among social media followers. BESC is instrumental in increasing a brand’s perceived value and word of mouth. This study aims to investigate the influencer-based factor (perceived influence, alongside consumer centric factors (value co-creation and social media marketing [SMM] activities) as antecedents for BESC in the influencer marketing context. Furthermore, the study tests the moderating role of product involvement on these relationships. Responses were collected through a self-administered online questionnaire which yielded a sample of 202 social media users in Malaysia. Analysis through IBM SPSS demonstrated that value co-creation and SMM activities of influencer-endorsed brands are significant predictors of BESC, while perceived influence does not contribute to BESC. Furthermore, product involvement exerted a moderating effect on all three direct relationships of perceived influence, value co-creation, and SMM activities on BESC. The research framework contributes to a greater understanding of BESC antecedents and the role of product involvement in influencer marketing context. The higher the level of product involvement, the larger the propensity for followers to form BESC through recommendations of influencers. This study can be beneficial to marketing managers that are building their own influencer marketing campaigns through incorporating value co-creation and SMM activities in their brand engagement strategy.
