Authors: Çamlibel Osman , Ayata Ümit , Peker Hüseyin
Published: December 2024

Calcium lignosulfonate (CLS) (C20H24CaO10S2) is widely used in various industries today, including wood, construction, food, agriculture, and textiles. It has been noted that there are currently few studies on the addition of CLS chemicals to various fiberboards. This study was designed to explore the outcomes of the interaction between CLS and the boards, with the aim of expanding the potential applications of this chemical. In this study, we incorporated CLS at varying percentages (6%, 8%, and 10%) as an adhesive additive in high-density fiberboard (HDF) produced using urea-formaldehyde (UF) resin in a laboratory setting. We assessed its impact on several physical properties [thickness swelling (TS), density, and water absorption (WA)] and mechanical properties [modulus of rupture (MOR), internal bond strength (IB), modulus of elasticity (MOE), and surface soundness (SS)]. A control group was established using prepared boards, allowing for a comparison of results between boards made with and without CLS additives. According to the results of a multivariate analysis of variance, the CLS percentage showed no significant effect on density, MOE, and SS. However, it significantly influenced TS, WA, IB, and MOR, resulting in reductions of 4-12% for SS, 6-12% for MOR, and 2-22% for IB, while increasing TS by 20-130%, WA by 25-84%, and MOE by 1-3%. It was observed that the use of CLS in the study led to differing results in the tests conducted on the produced HDF materials.

Authors: González R. Lourdes , Merino G. Consuelo , Códova B. Teresa , López N. Mercedes
Published: December 2024

Persistent Covid (PC) represents a post-infectious complication of SARS-CoV-2 infection, characterized by symptoms that persist for more than 12 weeks after the acute phase. These symptoms, which include chronic fatigue, respiratory distress, cognitive dysfunction, and other multisystem effects, significantly impact the quality of life of the affected individuals. The underlying pathophysiological mechanisms are complex and not yet fully understood, although studies have suggested a multifactorial origin. Proposed factors include viral persistence, immune dysfunction, autoimmunity, endothelial dysfunction, coagulation disturbances, and gut dysbiosis. The identification of these mechanisms could facilitate the development of diagnostic and therapeutic strategies, opening new perspectives for the effective management of persistent Covid. The diagnosis of PC is complex due to the diversity of symptoms and the lack of specific biomarkers. At present, therapeutic approaches focus primarily on symptomatic relief, but further research is required to fully elucidate the mechanisms underlying PC and to develop targeted interventions. This review synthesizes current evidence on the pathophysiological mechanisms of persistent Covid-19, highlighting recent advances and identifying key areas for future research.

Published: December 2024

Persistent COVID (PC) is the term used to describe a multisystemic and multifactorial entity, which follows acute SARS-CoV-2 infection. Symptoms must persist for three months or more to define this disorder. The clinical manifestations are variable and nonspecific, but have a great impact on the quality of life of patients. Neuropsychiatric symptoms are commonly reported in CP, mostly chronic fatigue, cognitive disorders, attention disorders, among others. The pathophysiological mechanisms are not fully known, but the most described are hypoxia related neuronal damage, microvascular lesions, a persistent proinflammatory state, activation of latent viral infections, and alteration of the blood-brain barrier. There are no specific complementary tests to confirm the diagnosis of CP. There is also no specific treatment to date and most therapies are aimed at relieving symptoms and improving quality of life. This article provides a comprehensive bibliographic review of the most common neuropsychiatric manifestations of CP, including its probable pathophysiological mechanisms and the therapies proposed to date.
Corazón resiliente: una aproximación a la afección cardiaca en Covid prolongado

Published: December 2024

The post-Covid-19 pandemic period has raised several questions regarding the new conditions associated with SARS-CoV-2 infection, one of which is the so-called long Covid. Among its characteristics, cardiac involvement stands out as a central element of this new pathology. From a pathophysiological perspective, there are different mechanisms through which this condition could be triggered, either directly due to the subacute inflammation of the initial hyperinflammatory disease, or indirectly, associated with the activation of autoimmune mechanisms. Clinical manifestations encompass a spectrum of symptoms and signs associated with major cardiological syndromes, such as palpitations, dyspnea, dizziness, or angina. Each of these symptoms reflects the involvement of different cardiac structures, grouped into manifestations of the conduction system, heart failure, cardiomyopathy, pericarditis, and acute or chronic coronary heart disease, respectively. To date, the existing literature on the diagnosis, treatment, and prognosis of these different conditions is limited, based on the identification of predictors derived mainly from retrospective observational studies. Similarly, recommendations are grounded in the extrapolation of previous knowledge in the field. We pose the question of whether prolonged Covid will be considered a new

Through this study, we seek to delve into the consequences that Long Covid had in the affective and emotional field of people with this condition, their knowledge about the changes that it entails, and how they perceive their daily lives regarding the repercussions they present. A qualitative, post-positivist, ethnographic research methodology will be used to achieve this. A sociodemographic file was implemented as a data collection technique, and in-depth interviews were conducted. A sociodemographic file was applied as a data collection technique, and in-depth interviews were conducted. According to the inclusion criteria, this study included six people chosen through the snowball technique. In terms of data analysis, interview transcripts were made, coded and categorized concerning the social representations shared by participants. This was followed by a second analysis using the outputs and inputs of Callista Roy’s nursing model. Ultimately, three main categories were obtained: the affective field, where feelings and emotions such as sadness, fear, and concern, among others, stand out; the cognitive field, including the patient’s knowledge about this syndrome, in which it becomes evident the little information available, and the representation field, that describes the significant changes it has meant for them in their daily lives.

Rol de la alteración del eje microbiota-intestino-hígado en la enfermedad hepática esteatósica asociada a disfunción metabólica
Authors: Ortiz-López Nicolás , Acevedo Maximiliano , Vergara Tamara , Aleman F. Larissa , Poniachik T. Jaime , Beltran M. Caroll J.
Published: December 2024

Metabolic dysfunction-associated steatotic liver disease (MASLD) is one of the leading causes of liver morbidity worldwide, including conditions such as hepatocellular carcinoma and the need for liver transplantation, with a particularly high prevalence in Latin America. The pathogenesis of MASLD is multifactorial, involving both genetic and environmental factors, including dysfunction of the gut-liver axis. The mechanisms involved in the progression of liver disease to cirrhosis are not yet fully understood. Recently, the intestinal microbiota has been recognized as playing a crucial role in disease progression by modulating systemic and hepatic inflammatory responses. In MASLD patients, microbial dysbiosis contributes to intestinal barrier dysfunction, increasing intestinal permeability and facilitating the translocation of microbial products to the liver, thereby exacerbating inflammation and hepatic damage. Additionally, alterations in bile acid levels and microbial metabolites further reinforce this pathological cycle. Therapeutic strategies aimed at restoring microbial balance—such as fecal microbiota transplantation, probiotics, prebiotics, and synbiotics—have shown promising results in modulating the microbiota-gut-liver axis and slowing MASLD progression. Further studies are needed to fully understand their impact on the pathophysiology of MASLD and to strengthen their integration into current therapeutic protocols for this disease.

Published: December 2024

Nitrogen Use Efficiency (NUE) is a key characteristic for sustainable agriculture to increase crop yield in parallel with reducing negative environmental impacts. Inm-Integrated Nutrient Management: Integrated nutrient management is an approach that integrates both organic and inorganic sources of nutrients & improves the productivity of crops and crop sustainability. Controlled release or stabilized nitrogen fertilizers better match plant needs with nutrient supply and reduce losses. Crop rotation and diversification approaches are used to improve NUE by maintaining soil fertility, pest management, and enhancing crop productivity. Organic amendments are essential in enhancing soil health and can serve as drivers of carbon sequestration as well as facilitate optimized nutrient cycling. There are challenges associated with NUE optimization, regardless of the sophistication of technology. The mentioned requirements are a better linkage between crop and livestock systems, development of more reliable NUE indicators, and adjusting precision farming for the sustainability. The path forward should concentrate on strategies that are innovative like improved crop sequences and sensor-based fertility management systems as well as an intensification which is sustainable. This group of problems required a high level of efficiency in nitrogen use as well as a decent performance of crops and mitigation of environmental degradation. Such holistic approaches combine the agronomic, genetic, and technologic dimensions into a long-term effort to conquer the exigencies of feeding the world’s population without adversely affecting ecosystem health.
Rural Electrification – A step towards Sustainable Development
Authors: Sirguroh Momina
Published: December 2024

The diverse landscapes, climates and social structures across India’s numerous regions, encompassing approximately 0.586 million villages present a spectrum of economic prospects rooted in leveraging local resources carefully. Sustainable development relies on the prudent utilization of these resources. Among various resources energy stands out as a very crucial for the sustainable development of rural areas. Rural electrification plays a pivotal role in fostering sustainable development in India by facilitating economic growth and social progress. Despite efforts, only 44% of rural households have access to electricity. The Rajiv Gandhi Grameen Vidyutikaran Yojana (RGGVY), a national renewable energy scheme, aims to address this gap outlined in the National Common Minimum Programme (NCMP). While significant investments have been made in physical infrastructure, the focus has been on development rather than effective management. Ensuring reliable 24/7 power supply to essential facilities is crucial. The success of initiative like RGGVY hinges on empowering State Electricity Boards (SEBs) to enforce regulations and ensure reliable service delivery, especially during peak demand hours in rural areas. This paper delves into the significance and challenges of rural electrification, exploring technical solutions and viable strategies to empower policymakers in utilizing electrical energy effectively.

La idea de texto desde las perspectivas de la lingüística del texto y de la teoría hermenéutica
Authors: López David E.
Published: December 2024

Esta investigación aborda la idea o noción del texto, ¿qué es un texto?, desde dos perspectivas: la de la lingüística del texto y la de la teoría hermenéutica, enfatizando las particularidades de cada una de ellas; pero orientándose por la teoría del texto desarrollada por la hermenéutica, que lo concibe de manera abierta y como portador de una autonomía semántica con relación a su autor, a sus primeros lectores y a su contexto original. Desde este enfoque, el artículo plantea preguntas que todo estudioso de textos literarios, filosóficos, históricos y teológicos debería responder: ¿es posible sostener que los significados de un texto son infinitos, acordes a quien los lea y a su contexto?, ¿son ilimitados los significados de un texto?, ¿son limitados los significados de un texto?, ¿puede hablarse de un significado verdadero o todos son igualmente válidos? En otros términos, ¿puede plantearse la idea de un significado predominante dentro de la multiplicidad y la pluralidad de significados? Todo esto replantea pero no resuelve un viejo problema de la antigua hermenéutica, y que se sigue manifestando en la nueva: el problema de la intentio auctoris, sensus auctoris o mens auctoris o, en otras palabras, el problema de si existe algo que podamos llamar el significado original que el autor haya dado a su escrito y, de existir, si éste se puede determinar con precisión; no obstante, el estudio se propone también el problema de la validez de las construcciones interpretativas del lector.

Os herbários são comumente relacionados à atividade de pesquisa, através da conservação de amostras de algas, plantas e fungos herborizados. Contudo, esse tipo de coleção biológica apresenta um grande potencial de integração dos campos de ensino, pesquisa e extensão. Deste modo, o projeto intitulado “Herbário do Setor Palotina: integrado à extensão na UFPR” foi concebido com o intuito de integrar a coleção de plantas e fungos herborizados da UFPR - Setor Palotina, denominada Herbário da Flora e dos Fungos do Oeste do Paraná - FFOP, às escolas da região, buscando fornecer materiais que auxiliassem no processo de ensino-aprendizagem da botânica, assim como desenvolver abordagens que pudessem contribuir para minimizar o desinteresse dos estudantes por essa área. Dessa forma, esse texto teve como objetivo elencar e analisar os resultados obtidos ao longo do primeiro ano de implementação do projeto. Através da interação dialógica foram desenvolvidas atividades como oficinas e visitas de escolas da região. Foram coletadas plantas no campus Palotina para o preparo de material didático bem como de materiais usados na feira anual “Vem pra UFPR”, evento este que oportunizou o contato com as escolas. Ao todo, 345 alunos participaram das ações desenvolvidas no herbário, e cerca de 2000 visitantes passaram pela Universidade durante a feira. Também foram confeccionados 48 materiais didáticos na forma de exsicatas para serem utilizados no âmbito escolar. Além de consolidar o herbário como um ambiente extensionista, o projeto também reafirma o compromisso com a comunidade escolar local ao suprir a demanda por materiais de ensino.

Bidirectional Deep Learning Model based on Attention Mechanism in English Cloze Tests
Authors: Yuan Haoshan
Published: December 2024

English cloze tests, as a common form of language assessment, aim to evaluate learners' comprehensive understanding of context, vocabulary, and grammar. However, the complex contextual relationships and long-distance dependencies within the questions pose significant challenges for machine learning models. Traditional rule-based or statistical methods struggle to effectively capture the intricate contextual information present in sentences. This study aims to develop a deep learning-based English cloze test answering system to enhance students' ability to tackle such questions. To address the limitations of traditional methods in handling complex contexts and long-distance dependencies, a model that combines bidirectional gated recurrent units (BiGRU) and attention mechanisms is proposed. This model is better equipped to capture the surrounding context of sentences and dynamically adjust attention to accurately predict the missing words. Additionally, integrating the embedding layer with BiGRU and attention mechanisms further improves model performance. Testing results based on the Children’s Book Test dataset are highly promising. Our model excels in key metrics such as accuracy, recall, F1 score, and Cohen's Kappa, achieving scores of 77.5%, 77.5%, 0.758, and 0.7649, respectively. Compared to traditional models, our approach demonstrates clear advantages in handling complex contexts and long sentences. This research provides new technical support for developing more intelligent English learning systems.
Comparative Analysis of Traditional and Hybrid Engines: Efficiency and Emissions
Authors: Zhao Yiming
Published: December 2024

As two dominant types of automotive engines, traditional internal combustion engines and hybrid engines hold significant market shares. This paper focuses on comparing the efficiency and emissions of these two engine types. The traditional engine, characterized by its crankshaft linkage structure, presents both its best feature and its biggest drawback. This structure leads to substantial efficiency losses and increased combustion time, resulting in lower overall efficiency and higher environmental pollution compared to hybrid engines. On the other hand, hybrid engines boast a more intelligent system, offering three distinct modes that can be selected based on the required power. This flexibility enables hybrid engines to conserve energy more effectively, thereby achieving higher efficiency. Regarding emissions, hybrid engines can switch between electric power and internal combustion depending on the situation, resulting in healthier emissions profiles. This paper aims to elucidate the operational differences and environmental impacts of traditional and hybrid engines, encouraging readers to form their own opinions on potential improvements for these technologies.
