Authors: n Sidar , Aydemir Selim , zmen Murat , lc Oktay
Published: January 2025

Aim: Ischemia with non-obstructive coronary artery disease (INOCA) is when there is myocardial ischemia without occlusive coronary artery disease. Over time, this could result in a reduced quality of life, frequent hospital visits, and a higher risk of cardiovascular-related deaths. Diagnosis, management, and prognosis of INOCA pose challenges. Lactate-albumin ratio (LAR) has been associated with mortality from many cardiovascular diseases. The study examined the link between LAR and mortality in patients with INOCA.
Material and Method: The study began by analyzing the data of 987 patients who visited our center between 2017 and 2023 and were diagnosed with myocardial perfusion imaging with single photon emission computed tomography (MPI-SPECT) showing ischemia. We included 279 patients in the study after applying the exclusion criteria. Medical histories, laboratory parameters, and patient death information were recorded.
Results: The mean follow-up time was 205±47 days. Mortality occurred in 5% of patients (14 patients). Patients were divided into two groups: mortality and non-mortality. While LAR was 0.65 ± 0.26 in the non-mortality group, it was 1.05 ± 0.32 in the mortality group, demonstrating a statistically meaningful dissimilarity between the two groups (p=0.017). Cox regression analysis was conducted to determine mortality predictors. Age and LAR emerged as independent predictors of mortality in INOCA patients (p=0.03 and p=0.005, respectively). We utilized Receiver Operating Characteristic (ROC) analysis to consider the effectiveness of LAR in predicting mortality. As a result of the examination, the area under the curve (AUC) was determined as 0.689 (0.519-858), the cut-off was 0.656, the sensitivity was 57.1%, and the specificity was 52.8% (p=0.017)
Conclusion: Our study found that LAR performs as an independent predictor of mortality in patients with INOCA.

Background and Aims:
Osteoarthritis (OA) is the most common degenerative disease of the knee joint and can cause severe disability. Successful preventive methods depend on a high level of awareness among the general population. Therefore, the current study investigates the awareness about the knee OA among the general population in the Hail region of Saudi Arabia.

Methods:
A cross-sectional study was carried out in the Hail region of Saudi Arabia. A total of 268 participants were included in the final survey analysis. A 36-item, self-administered questionnaire was used to collect data to measure the knowledge level of the participants regarding OA of the knee. Descriptive analysis, an unpaired sample t-test, and one-way analysis of variance (ANOVA) were con¬ducted. Multiple linear regression was used to investigate the demographic variable associated with the total knowledge level.

Results:
Of 268 participants, 61.2 % had a high level of knowledge about OA of the knee. The regression analysis revealed that being female was associated with a higher total knowledge level and that being unemployed was associated with a lower total knowledge level.

Conclusions:
The present study revealed that people have a satisfactory level of knowledge about knee OA in general. However, further research is needed to increase awareness in the subdomain through awareness campaigns.
Knowledge and attitude among adolescent boys of age group 13-17 years regarding menstruation in urban Jabalpur, Madhya Pradesh: A study of Central India
Authors: Jayamohan Anusree , Tomar Shashi
Published: January 2025

Background and Aims:
In India, menstruation is considered a “women’s” problem because the majority of studies on the subject only include girls and women. This discussion excludes adolescent boys, which obscures the fact that menstruation is a social epidemiological phenomenon with persistent gender differences. To encourage boys to contribute significantly to women’s health, study on their menstrual knowledge, attitudes, and experiences, including socioeconomic aspects, must be conducted. This must be addressed if gender inequalities in adolescent health are to be reduced. Hence the current study is undertaken to investigate the knowledge and attitudes of school-aged adolescent boys in urban Jabalpur toward menstruation, taking into account factors like as family structure, societal behaviours, and cultural influences.

Methods:
Cross-sectional research of 100 males aged 13 to 17 years from Jabalpur, Madhya Pradesh, was carried out using the multistage random sample approach.

Results:
Menstruation was met with a mixture of wonder and embarrassment. Many people were uninformed and lacked proper understanding. Out of 100 males, 48% had good knowledge and 27% had a good attitude toward menstruation. The majority of the children got their information from schools (45%) followed by their parents or their peer group (39%). Most schools do not provide adequate sex education. Boys who have sisters or female acquaintances have more awareness and a positive attitude toward menstruation.

Conclusions:
The study emphasizes the importance of considering not only individual factors but also social dy¬namics when analysing knowledge, attitudes, and personal group scores. These findings contribute to a more comprehensive understanding of the factors influencing individuals within a social context for improving Indian boys’ understanding and beliefs about menstruation and their menstruation-related experiences.

Authors: Almuzaini Hanan , Shahat Khaled , Almuzaini Sara , Hafiz Badr , Alreefi Nora , Hawalh Reham
Published: January 2025

Background and Aims:
The Universal Newborn Hearing Screening (UNHS) program in Saudi Arabia has proven instrumental in curbing the burden of neonatal hearing loss in the country. Recent studies from Saudi Arabia have shown a high rate of neonatal hearing loss and follow up default, along with poor awareness among parents, in the Madina region of the country. The study aimed to investigate the prevalence and causes of neonatal hearing loss and follow-up default, among newborns screened at the Children and Maternity Hospital in Madina, Saudi Arabia.

Methods:
All 500 neonates who were born at the hospital from January 2021 to January 2022, and underwent UNHS were included. Prevalence and causes were expressed as descriptive statistics. A chi-square test was used to correlate clinical risk factors with the occurrence of neonatal hearing loss. A P value <0.05 was considered statistically significant.

Results:
The prevalence of neonatal hearing loss was 1.2%, with 17.8% follow-up default. Exposure to ototoxic drugs, low birth weight, craniofacial anomalies, neonatal intensive care unit admission, maternal age >30 years, and hereditary risk showed a statistically significant correlation with neonatal hearing loss. Transportation difficulties (33.7%), lack of education (28.7%) and poor economic condition (21.8%) were the top causes of follow-up default.

Conclusions:
The study reiterates the dire need to raise awareness among parents of newborns regarding the detrimental effects of neonatal hearing loss, the importance of the UNHS program and the necessity for complete follow-up. A wider and more efficient network of screening and referral centers is needed. Research studies conducted at individual institutions can help identify and address the inadequacies of the UNHS program at a grassroots level.

Self-Induced Cauliflower Ears: A Case Report of an Unusual Cause
Authors: Alshehri Ali
Published: January 2025

Cauliflower deformity of the ear is commonly presented due to blunt trauma to the auricle. The common forms of blunt trauma are sports (boxing, wrestling, and martial arts), motor vehicle accidents, especially without wearing protective helmets, and child/adolescent abuse. Self-injurious behavior, particularly in individuals with certain psychological or developmental disorders, can indeed lead to a cauliflower ear if the person repeatedly hits, punches, or otherwise injures their ears. This type of behavior can cause trauma similar to what is seen in contact sports. Over time, repeated injury could result in the same kind of damage. Here, the author reports a case of an unusual cause of this deformity which is habitual play as a self-induced trauma. A 32-year-old clerk officer male patient presented with both deformed ears. The deformity of the left ear was worse than the right one. The patient has no fluctuation or other inflammatory signs during the examination. His medical, psychological, and dermatological history was free. The patient used to play with his ears to enjoy his friends for 2 to 3 years. His management is a triad of behavioral therapy, reassurance, and topical steroids. We present this unusual cause of cauliflower deformity of both ears which is the first case published in the literature up to our knowledge.
Lignin degradation dynamics in boreal forest soils : influence of chemical composition and nitrogen on lignin degradation
Authors: Thirunavukkarasu Aswin
Published: January 2025

Soil organic matter (SOM) is a critical component of the global carbon cycle, storing more organic carbon than the atmosphere and global vegetation combined. Plant-derived organic inputs are the primary carbon source for SOM formation, which arises through the microbial decomposition processes. Among these inputs, lignin, a complex biopolymer abundant in plant biomass, is often considered a key contributor to SOM due to its resistance to degradation. However, the influence of lignin’s moieties on SOM stability remains poorly understood. In this thesis, I have investigated the lignin decomposition and its contribution to SOM formation using Aspen wood (Populus tremula) genotypes with varying lignin content and composition as model substrates. Laboratory incubations (Paper I-II) and field experiments (Paper III), coupled with advanced two-dimensional Nuclear Magnetic Resonance (2D NMR) spectroscopy, were systematically employed to characterize the degradation of lignin moieties. In Paper I, lignin content did not affect overall decomposition, with approximately 60% mass loss across substrates. While the lignin decomposed at a similar rate to carbohydrates, oxidized syringyl units exhibited resistance to degradation compared to other lignin monomers. Paper II demonstrated that nitrogen addition altered fungal community structure, suppressing the ligninolytic fungus Renatobasidium notabile and increasing fungal diversity. This shift enhanced the degradation of more resistant lignin moieties, such as guaiacyl units and their linkages. Paper III demonstrated that lignin composition, rather than content, is crucial in early-stage decomposition across pine and spruce forest stands. Long-term nitrogen fertilization enhanced mass loss but selectively degraded syringyl units and their linkages. These findings highlight that lignin composition and microbial community dynamics regulate decomposition rather than lignin content alone. This emphasizes the need to focus on microbial and compositional factors to better understand SOM dynamics and carbon cycling.
Virus yellows of sugar beet – exploring pathogen diversity and host resistance : groundwork for resistance breeding
Authors: Puthanveed Vinitha
Published: January 2025

Sugar beet (Beta vulgaris ssp. vulgaris) is a crop primarily cultivated in temperate regions of the world for its high content of sucrose stored in the tap root, which is processed to obtain sugar. The yielding capacity of the crop is threatened by several biotic stresses with virus yellows (VY) being among the viral diseases causing significant yield losses. In Europe, VY is caused by beet mild yellowing virus (BMYV), beet chlorosis virus (BChV) and beet yellows virus (BYV). The main vectors for these viruses are the green peach aphid and the black bean aphid. Insecttransmitted diseases are on rise due to climate change and pose a large threat. We explored the diversity of viruses causing VY in Swedish sugar beet and the incidence of turnip yellows virus (TuYV) in oilseed rape with samples collected from different parts of Sweden in the year 2019. The analyses revealed mixed infections of BMYV and BChV in most of the sugar beet samples and two samples had a triple infection together with TuYV. The survey in oilseed rape revealed a high TuYV incidence with an average infection rate of 75% in the counties of Skåne, Kalmar and Östergötland. With the ban of neonicotinoid chemicals used for managing aphid vectors, there is a greater need for developing resistant or tolerant cultivars as a sustainable alternative. In this study, our aim was also to gain more insights into BMYV – host interactions using transcriptomics and a BMYV-resistant genotype of wild beet in comparison to a susceptible genotype of sugar beet. Virus quantification by RT-qPCR revealed that the wild beet was partially resistant. In the susceptible genotype, a large number of genes were differentially expressed as a response to BMYV infection, while the transcriptomic response of resistant plants was weaker. In the resistant genotype, the differentially expressed genes included seven significantly upregulated genes, which encoded proteins involved in protein processing in the endoplasmic reticulum (ER). This could be one of the mechanisms contributing to the ability of the wild beet genotype to manage ER stress induced by BMYV infection and to reduce the virus level. To identify genomic regions associated with symptom development and BMYV titre, QTLseq and QTL mapping were carried out using F2, S1 and S2 populations of wild beet × sugar beet. These Virus yellows of sugar beet – exploring pathogen diversity and host resistance: Groundwork for resistance breeding studies showed that not a single gene was responsible for the responses to BMYV and reduced virus titre, but rather that these traits are governed by multiple loci with minor effects. One significant QTL was identified on chromosome 1 that was linked to reduced virus titre in leaves and explaining 16.7% variation in the trait. Overall, these results would lay a strong foundation for resistance breeding against VY disease in sugar beet.

Powder metallurgy (P/M) is a typical process for producing metal parts and metal matrix composites by employing powder-form materials. The main challenge to the economic viability of P/M components is the expense of die-making, especially when producing small quantities of parts. Pressure-less sintering is a promising approach in P/M, with the potential for efficient and cost-effective manufacturing through the use of customised dies produced through 3D printing. This study examines the wear characteristics of pressure-less sintered copper pins produced in 3D-printed clay moulds. The research focuses on Pin-On-Disk wear testing and microhardness to assess the component quality and to understand the wear rate of these pins under different loading conditions, viz. sliding velocities and applied load.
Moreover, the study aims to demonstrate the effectiveness of the combination of pressure-less sintering through 3D Printed clay moulds highlighting its potential for producing durable copper pins. Through a comprehensive investigation into the wear performance of components synthesized by the integration of pressure-less sintering and 3D printing technologies, known as Additive Manufacturing. Based on experimental investigation it has been observed that sliding speed and applied force have a direct impact on wear rate. In particular, the applied load has a major influence on the wear rate in pin-on-disc wear tests for the same sliding distance.

The hobbies are now very important components of our lives, and model railroading is one of them. Nowadays, the realism and detailing of both model trains and scenery become more and more important. The medium-sized and big sized railway stations of the extended digital model railway systems are the most difficult to replicate, firstly because of their uniqueness (dimensions, shapes, buildings, trackwork, signals etc), then because of the multiple light boards that display the current time (using analog or digital format), the train numbers, routes, arrivals and departures, announcements, advertising etc. For a long time, these important miniature items were completely static and very rarely illuminated, but now, with the occurrence of the new LED lighting technologies, this is about to change. The authors have designed and made some digital microcontroller-driven modules with OLED miniature panels that are able to successfully replicate the above-mentioned dynamic and fully-functional light panels, which can operate either standalone or driven by the DCC signal of the present model railway system. The results are promising and yield a lot of opportunities for future development. The authors have already written a series of papers about improving other aspects of analog and digital model railroading, such as intelligent boosters, sensors, controllers, signal quality detectors, automation devices etc.

Laser surface texturing (LST) technology improves the surface morphology and characteristics of materials by modifying their texture and roughness. The different behaviors during wettability test, depending on the texture pattern and number of passes suggest a complex dependence on the surface microstructure and the dynamics of surface energy change. Laser texturing significantly alters the coefficient of friction (COF) and wear behavior of the materials analyzed in this study PA6.6 and PA6.6 reinforced with glass microspheres. The increase in surface roughness after texturization is the main factor driving the higher COF values. Textured patterns have a functional role in the accumulation of wear debris, which contributes to the improvement of the wear behavior of textured surfaces. All tests showed a weight increase after degradation, suggesting incomplete degradation or chemical reactions with the test environment. The studied materials can be used in industrial applications such as functional coatings, components in the filtration industry, wear parts in the mechanical industry.

Under the general name of are understood the constructions composed of pipes, joining parts and their accessories, with which auxiliary constructions are executed that serve to execute the final ones, after which they are dismantled and the material is stored until a new use. The consecrated material for these constructions was wood. Along with the advance taken by the final civil and industrial constructions, the need to replace wood with metal material appeared. The use of metal brought a series of advantages and the achievements with the help of metallic materials proved remarkable. At the moment, the basic elements of these constructions are mild steel pipes, assembled with joints pieces and removable accessories, thus constituting a metal structure that can be used in the most varied forms. In this way, unlike the definitive metal constructions in which the sections of the constituent elements each correspond exactly to the effort it must withstand, at the temporary constructions the problem is solved by an easy-to-manipulate material, with elements that can be changed between them. Within the frame of this work, it is wanted to address two aspects, namely: the general behavior of a temporary auxiliary construction made of steel pipes (scaffold type) under the action of functional loads; the analysis of a joining element from the scaffold componency, an element that allows the assembly of two pipes in orthogonal directions. The approach to the two aspects mentioned was possible using tools made available by a specialized software of finite element analysis namely Femap.
Explore the Role of Synergy Agglomeration between Producer Services and Manufacturing Industry on Carbon Productivity
Authors: Wu Qing , Cao Xueqin
Published: January 2025

This paper, based on the provincial data of China from 2012 to 2022, employs a two-way fixed panel model to empirically study the impact effect and transmission mechanism of the collaborative agglomeration of manufacturing and producer services on regional carbon productivity. The study finds that: the collaborative agglomeration of manufacturing and producer services can significantly enhance regional carbon productivity, with a clear function of energy saving, carbon reduction, and efficiency improvement. Non-linear impact analysis reveals that the relationship between the two presents a distinct "U" shape, with the promotional effect strengthening after passing the inflection point. Heterogeneity analysis shows that regions at different levels of manufacturing agglomeration and producer services agglomeration exhibit varying degrees and significance of impact on carbon productivity from the enhancement of the two industries' collaborative agglomeration, and the inflection points where the effect strengthens are also inconsistent. The analysis of transmission mechanisms reveals that the collaborative agglomeration of the two industries can always influence carbon productivity by promoting the optimization of factor structure, industry scale expansion, and technological progress, while the impact on industrial structure optimization and technological efficiency optimization presents a "U" shape, characterized by long-term and dynamic nature.

Published: January 2025

To address the issues of discontinuous contact lines and sharp points on the tips of the gears in the cycloidal-involute rotor end profile of existing twin-screw vacuum pumps, a fully smooth rotor profile for twin-screw vacuum pumps is proposed. A concentric arc meshing model and a tip elliptical arc correction model are established, and the rotor profile equation is derived. Three-dimensional modeling is completed along with dynamic interference analysis. Furthermore, a comparative analysis of the rotor's geometric characteristics is conducted, focusing on aspects such as the leakage triangle and area utilization rate. The research results indicate that after the correction of the concentric arc meshing model, the area of the leakage triangle is reduced to 51.1% of that before correction, and the effective area utilization rate of the rotor end face is significantly improved.

It is undeniable fact that an analytical and enlightening deliberations of translation in the last decade have focused on questions of ideology; certainly, a productive academic dialogue about various facets of the ideology is going on at various levels. The ideology in translation is a subject discussed by many translation scholars talking about culture, gender, etc. but not often talking about the ideological background of the translators while dealing with the religious text like the Holy Quran. Translation of the meaning of the Holy Quran as one of the religious books must be faithful and loyal to the original text for transferring the intended message of the source text without intervention of the translator’s ideology by adopting addition or manipulation or any other translation strategies so that the intended message of the source text of the Holy Quran may be transferred to the readers of the target text accurately without any ambiguity. This study examines the English translation of the meanings of the Holy Qur’an by George Sale who has Christian ideological background, and Muhammad Abdullah Yusuf who has Muslim ideological background. The research investigates the intervention of the religions ideological factor in translating the meanings of the Holy Quran. Some Quranic verses have been selected for analytical study to explore and examine to what extent the ideology of the translators having different ideological background effects on translation of the Quranic text.

We derive topological and geometrical properties of cusped connected orientable $3$-manifolds obtained by face pairings of the nonregular cube, which are reducible to two-generator fundamental groups. Besides the polyhedral schemata, we derive geometric presentations of the fundamental group, which correspond to spines of the manifolds. Then, we provide simple surgery descriptions of the considered cube manifolds.

O debate sobre a Educação Ambiental é pertinente para a sociedade atual, tornando-se fundamental para a sobrevivência humana, já que a gravidade das danosas consequências causadas ao meio ambiente pela ação irresponsável da sociedade, o avanço do capitalismo e a evolução a cada ano das indústrias que exploram cada vez mais a natureza agravam os problemas ambientais. O objetivo geral deste trabalho é identificar o que os alunos de licenciatura em Geografia, matriculados em 2023, no semestre 2022/2, pensam sobre Educação Ambiental, e como a Geografia contribui para essa questão. Para isso, analisou-se o Projeto Pedagógico de Curso - 2019 (PPC), averiguando quais matérias adentram ao assunto. Essa análise foi realizada por meio de questionário, dada a importância do estudo para os futuros profissionais da educação. A Educação Ambiental tem o enfoque de conscientizar os seres humanos sobre ações e conhecimentos relativos à relação sociedade e natureza. Esta pesquisa busca discutir a Educação Ambiental no ensino escolar em nível superior. Apesar de a Educação Ambiental ser legalmente instituída, percebe-se que não se mostra eficiente em minimizar os impactos ambientais causados pela sociedade do consumo.

O presente trabalho apresenta um relato de experiência de um projeto sobre educação ambiental realizado em uma escola do município de Araguaína – TO. Considerando a necessidade de fundamentar as práticas aplicadas, o objetivo é compreender o papel da interdisciplinaridade e a importância de integrar os princípios dos 3 R’s (reduzir, reutilizar e reciclar) no processo educativo, utilizando como suporte o livro didático. Busca-se, ainda, investigar de que forma os livros didáticos podem ser utilizados para alcançar as habilidades previstas nos documentos norteadores. A abordagem metodológica adotada foi qualitativa, por meio de pesquisas descritivas e bibliográficas. Inicialmente, foi realizada uma coleta de dados a partir de atividades desenvolvidas em sala de aula, com base nas sugestões apresentadas pelos livros didáticos. Em seguida, foi realizada uma pesquisa bibliográfica em livros e artigos científicos. Por fim, as atividades realizadas em sala, voltadas à educação ambiental, foram detalhadas. Os resultados demonstram que a interdisciplinaridade tem a finalidade de romper com a fragmentação dos saberes, e que a política dos 3 R’s pode ser aplicada ao cotidiano dos alunos de forma interdisciplinar. Quanto ao uso do livro didático, cabe ao professor fazer as adequações necessárias para alcançar as habilidades previstas, o que impõe a constatação de que através da interdisciplinaridade é possível conduzir os alunos a um saber mais contextualizado.

Este artigo apresenta a experiência do projeto de educomunicação intitulado EDUCA LAPA: Educação Conectada com Você, materializado por meio de um programa de rádio que propõe o uso das mídias na educação através da produção de conteúdos educativos, realizado pelo município de Bom Jesus da Lapa, BA.O projeto surgiu a partir da seguinte questão: como auxiliar os alunos durante a crise sanitária provocada pela COVID-19, garantindo o acesso à informação necessária sobre os conteúdos escolares desenvolvidos pela rede municipal de ensino? Assim, o objetivo foi socializar os conteúdos educativos desenvolvidos pela rede municipal de ensino e apoiar os alunos em seus estudos, promovendo a interação entre estudantes, pais, professores, gestores e a sociedade civil. As edições do programa eram elaboradas pela assessoria de comunicação da Secretaria Municipal de Educação (SEMED) em colaboração com as unidades de ensino, sendo transmitidas três dias por semana, com um desses dias destinado especificamente ao público da Educação de Jovens e Adultos (EJA). Essa experiência teve grande repercussão em toda a região, alcançando ampla audiência e engajando todos os segmentos da sociedade. Os resultados mostram que os estudantes jovens e adultos, ao participarem do programa como protagonistas dessa ação, obtiveram maior motivação para os estudos e, consequentemente, melhor rendimento na aprendizagem escolar. A comunicação tornou-se mais acessível e possibilitou o desenvolvimento de diversas habilidades, tanto que o projeto continuou com uma nova abordagem após o período pandêmico.
