Authors: Almohammad-albakkar M. , Al-Deewan Hayder A. O. , Al-Wadi Wadi M.
Published: May 2024

Over centuries, natural phenomena have claimed a large number of lives and caused large amounts of damage. However, they were the reason for the development of knowledge and science. In engineering, there is no doubt that earthquakes were the driving force behind many design philosophies and advanced technologies. In this regard, steel plate shear walls (SPSWs) represent one of the technologies employed in both new constructions and existing structures to bolster lateral load resistance. In addition to its high elastic stiffness and strength, SPSWs often experience significant pinching during their hysteretic response unless heavily stiffened. Thus, numerous investigations have been performed recently to enhance the seismic behavior of SPSWs during severe ground shaking. The shear walls of steel plates have been studied in various ways, including stiffened and unstiffened steel plates, low yield strength steel plates, SPSWs perforated with circular holes or vertical slits, steel walls with stiffened and unstiffened openings. A stiffened SPSW panel dissipates significantly more energy than an unstiffened panel, as well as exhibiting a ductile and stable behavior. In view of its high elongation, the SPSW with low yield point has the best damping capacity. It has been demonstrated that steel walls perforated with circular holes have improved energy dissipation, in addition to allowing utilities to pass through their openings. Vertical slits on steel plate shear walls produce an exceptionally full hysteresis loop with improved performances. Slit steel walls (SSWs) can sustain a drift of over 3% while experiencing minimal hysteresis degradation. Additionally, a frame with a SSW can endure up to 6% drift without significant damage, surpassing expected ductility levels of a special moment frame, particularly with efficient slit geometry.

Authors: Rafi Al Mahmud
Published: April 2024

The COVID-19 pandemic forced several Bangladeshi private universities to move from in-person to online classes. This paradigm shift has facilitated a unique window of opportunities to harness the untapped potentials of e-learning practices in Bangladesh. However, it has posed a myriad of coping challenges for Bangladeshi students. This exploratory research was conducted to identify the seized learning opportunities along with the critical challenges experienced by the students while learning from online classes at a private university of Bangladesh. This research adopted a mixed methodology of combining both qualitative and quantitative approach for holistic insights. Quantitative data was collected through an online questionnaire survey on a representative and diverse sample size of 745 participants from ten different departments. Semi-structured in-depth interviews consisting of closed and open-ended questions were conducted on 20 respondents for in-depth findings. Primary findings demonstrate the underutilized potential of online classes such as adaptive personal learning, peer learning, gasification, collaborative problem solving, synchronized and synchronized communications etc. The primary challenges include inadequate infrastructural arrangements, lack of uniform and coherent guidelines, non-existence of incentives, limited access to devices, interrupted internet connectivity, poor speed of internet, high data price, limited or no prior orientation to online learning tools and techniques, tedious online class schedule, increased summative and formative tests, fatigue from overusing virtual platforms and physiological issues such as eye-strain, back pain, headache, dizziness from prolonged online classes, absence of face-to-face socialization etc. Based on these findings, this study recommends a few pragmatic strategies to harness the untapped opportunities of online learning and further ensure the viability and sustainability of online education in Bangladesh.

A Depressão Pós-Parto (DPP) é uma condição clínica de âmbito complexo que se manifesta como um distúrbio mental. Esta condição é caracterizada por uma profunda tristeza, um sentimento de incapacidade e uma falta de esperança que ocorre logo após o parto. A DPP é influenciada por uma variedade de fatores de risco. Estes incluem a história pregressa da mãe, fatores socioeconômicos e culturais, e condições relacionadas ao pré-natal, parto e puerpério. A história pregressa pode incluir experiências de vida da mãe, como traumas ou estresse, que podem aumentar a probabilidade de desenvolver DPP. Fatores socioeconômicos, como a falta de apoio social ou financeiro, também podem contribuir para o desenvolvimento da DPP. Além disso, condições relacionadas ao pré-natal, parto e puerpério, como complicações durante o parto ou problemas de saúde do bebê, podem aumentar o risco de DPP. Para entender melhor a DPP e seus fatores de risco, foi realizada uma pesquisa em várias bases de dados. Esta pesquisa incluiu artigos nos idiomas português e inglês, publicados a partir do ano de 2014. Todos os estudos selecionados foram lidos na íntegra para garantir uma compreensão completa dos resultados. A pesquisa destacou a relevância de vários fatores de risco para a DPP. Em particular, os fatores relacionados à mãe foram identificados como contribuintes significativos para o desenvolvimento da DPP. Estes podem incluir a saúde mental da mãe antes do parto, a experiência do parto e o apoio social disponível para a mãe após o parto. Além disso, a pesquisa também destacou os impactos econômicos e sociais da DPP no sistema de saúde. A DPP pode resultar em custos significativos para o sistema de saúde, incluindo o custo do tratamento médico para a mãe e o impacto a longo prazo na saúde e no desenvolvimento da criança. Além disso, a DPP pode ter um impacto social significativo, incluindo o estigma associado à doença e o impacto na família da mãe. Em resumo, a DPP é uma condição complexa que é influenciada por uma variedade de fatores de risco. A compreensão desses fatores é essencial para o desenvolvimento de estratégias eficazes de prevenção e tratamento. Além disso, é importante reconhecer os impactos econômicos e sociais da DPP e trabalhar para minimizá-los. Isso pode incluir a provisão de apoio adequado para as mães e suas famílias, bem como a educação do público sobre a DPP para reduzir o estigma associado à doença.

INTRODUÇÃO: Barodontalgia é a exacerbação de uma condição oral subclínica pré-existente, caracterizada por dor intensa, aguda e localizada, quando o paciente é submetido a alterações da pressão atmosférica. Essas mudanças podem ocorrer durante voos, mergulhos ou em câmaras hiperbáricas. O objetivo deste trabalho é dissertar sobre o papel do cirurgião-dentista frente ao tratamento e diagnóstico da barodontalgia. METODOLOGIA: Trata-se de uma revisão de literatura integrativa. Foram utilizados 07 artigos publicados nas bases de dados PubMed e LILACS, utilizando os descritores “pressão atmosférica”, “barodontalgia”, “dor no dente” e “odontologia” e suas respectivas traduções para a língua inglesa e espanhola. Os critérios de inclusão foram artigos em língua inglesa, portuguesa e espanhola, publicados nos últimos 10 anos. Os critérios de exclusão foram teses, dissertações, trabalhos de conclusão de curso e anais. RESULTADO E DISCUSSÃO: A prevenção da barodontalgia envolve uma avaliação cuidadosa da saúde bucal antes de atividades que envolvam variações de pressão. Presença de cáries, restaurações insatisfatórias, dentes com indicação de exodontia e indicação de tratamento endodôntico podem desencadear eventos de barodontalgia. O diagnóstico preciso da barodontalgia é fundamental para identificar a causa subjacente da dor e exige relato da história clínica detalhada associada a exames radiográficos. O tratamento preventivo inclui avaliações periódicas, tratamento restaurador de dentes cariados, remoção de restaurações insatisfatórias e eliminação das causas da inflamação dentária de um modo geral. O cirurgião-dentista deve orientar o paciente em relação ao tempo que deve esperar antes de ser submetido à alteração de pressão após procedimentos odontológicos. CONCLUSÃO: O cirurgião-dentista deve conhecer as causas e o manejo de pacientes com barodontalgia, bem como estar preparado para o uso de medidas preventivas e curativas, a fim de reduzir a incidência e a gravidade desta condição.

A differentiated approach to the diagnosis of overweight and obesity in children based on bioimpedance analysis of body composition
Authors: Palamarchuk Olga S. , Leshko Myroslav M. , Klushyn Vladyslav O. , Feketa Volodymyr P.
Published: May 2024

Aim: The current study introduces a novel diagnostic algorithm employing bioimpedance analysis to comprehensively evaluate body composition in children, assessing fat content, skeletal muscle content, and fat distribution.
Materials and Methods: Bioelectrical impedance measurements were obtained using the TANITA MC-780 MA analyzer. Indicators such as body weight, BMI, total fat content, absolute limb muscle mass, skeletal muscle strength, and waist-to-hip ratio (WHR) were assessed. A sample of 101 children aged 9 to 14 were studied using the proposed algorithm, refining BMI-based classifications.
Results: The algorithm comprises three steps, categorizing children based on fat content, presence of sarcopenia, and central fat distribution. It identified diverse somatotypes within the groups classified by BMI. Notably, it revealed prognostically unfavorable somatotypes, such as sarcopenic obesity with central fat distribution, highlighting potential health risks. Current BMI-centric diagnoses may misclassify cardiometabolic risks, making early detection challenging. The algorithm enables a detailed evaluation, unmasking metabolically unfavorable conditions like sarcopenic obesity. The incorporation of functional tests, such as a standardized hand-grip test, enhances diagnostic accuracy. The proposed WHR indicator for characterizing fat distribution provides a practical method for determining somatotypes in children.
Conclusions: This comprehensive algorithm offers an alternative to BMI-based classifications, enabling early detection of obesity and associated risks. Further validation through large-scale epidemiological studies is essential to establish correlations between somatotypes and cardiometabolic risks, fostering a more nuanced and individualized approach to pediatric obesity management.

Published: May 2024

Aim: To showcase a rare retinal lesion and the results of contemporary diagnostic and treatment of interferon-induced retinopathy.
Materials and Methods: We describe a case of a 36-year-old patient with interferon-induced retinopathy, with hepatitis C, that received prolonged interferon treatment. Clinical signs, examination and combined laser and pharmacologic treatment were showcased in the study.
Results: As a result of pharmacologic and laser treatment, the patient’s visual acuity increased from 0.1 to 1.0 through the duration of 3 months after treatment. The patients` condition remained stable under dynamic observation.
Conclusions: Because interferon-induced retinopathy is a rare occurrence in routine ophthalmologic practice, combined laser therapy can be used for treatment of preretinal hemorrhage, which leads to improvement of visual functions and stabilization of the retinal processes. This case is an addition to the few described cases of interferon-induced retinopathy.

Published: May 2024

The increase in demand for technology usage has influenced many sectors, including education. However, teachers’ and students’ perceptions have a great impact on the effectiveness of technology-enhanced teaching and learning. Therefore, the purpose of this study was to assess teachers’ and students’ perceptions of the use of technology-enhanced teaching and learning and find out if there was an association between teachers’ and students’ demographic characteristics and their perceptions of technology use in teaching and learning. A cross-sectional design was used to gather information from the field. Secondary school teachers and students in Dodoma City constituted the study population. 83 teachers and 393 students from 10 secondary schools were selected purposefully. The self-administered questionnaire was used to gather data from both categories (teachers and students). The data was analyzed by using percentages and statistical tests, including Chi-square goodness of fit and one-way ANOVA, to determine the association and relationship between teachers’ and students’ perceptions in relation to the selected demographic characteristics. The study found that teachers and students have positive perceptions of the use of technology in teaching and learning in public secondary schools. Furthermore, it was found that the education level of teachers, the class of students, and the age of teachers influenced the perceptions of the use of technology in teaching and learning. The study recommended that the government should ensure pieces of training for teachers, motivation, and a conducive environment for the use of technology in teaching and learning in secondary schools.

Authors: - Ch. Surya Kalyani , - D.S.L. Manikanteswari
Published: May 2024

There are millions of different types of mushrooms that grow all over the planet, but only one type is edible. Understanding how to differentiate between edible and dangerous mushrooms is an expertise that takes experience. Therefore, it's crucial to classify toxic and edible mushrooms. In addition to employing fungi's physical characteristics, machine learning (ML) techniques may be employed as well to distinguish between poisonous and edible mushrooms. Models will be developed to classify edible and deadly mushrooms based on features from the Mushroom collection and various distinct machine-learning algorithms. The results of this study were examined, and it was determined if the mushrooms were edible or dangerous by considering the physical characteristics of the mushrooms.

Published: April 2024

Bei der Erarbeitung einer "Gesamtkonzeption Lehrerbildung" durch die Erziehungsdirektion Bern stützen sich die Ueberlegungen zur künftigen Gestaltung der Lehrerbildung unter anderem auf Informationen über die Rekrutierung und Selektion von Lehrkräften. In diesem Zusammenhang wurden die Autoren beauftragt, wichtige Literatur zum Thema zu sichten und auszuwerten. Ferner wurden im Kt. Bern eigene Untersuchungen über die Rekrutierung und Auslese der Primarlehrer durchgeführt. Der folgende Text ist eine Kurzfassung der Berichterstattung über die Ergebnisse dieser Recherchen (ausführlicher Bericht: SLONGO/OBERLI/HEDINGER 1988). In der kritischen Diskussion der Ergebnisse wird darauf hingewiesen, dass der Literatur nur wenig konkrete Hinweise darauf zu entnehmen sind, wie die Auslese von Lehrkräften sinnvollerweise vorzunehmen sei.
Erfahrungen mit einer Kombination von Microteachin, Reflective Teaching und Unterrichtsbeobachtung.
Authors: Kramis Jo
Published: April 2024

Nach Ansicht verschiedener Lehrerbildner/innen sind die traditionellen Formen der Lehrerbildung nur bedingt geeignet, Lehrer/innen auf ihre künftigen Aufgaben im Klassenzimmer vorzubereiten. Verschiedene Lehrerbildungsstätten sind deshalb dazu übergegangen, die traditionellen Lehrveranstaltungen für Lehrer/innen durch Lehrertrainings (z.B. Microteaching, Reflective Teaching,...) zu ergänzen. Bringen solche Lehrertrainings tatsächlich das, was man von ihnen erwartet? Sind sie nachweislich wirksame Formen der Lehrerbildung? Lohnt es sich, traditionelle Lehrveranstaltungen für Lehrer/innen durch Lehrertrainings zu ergänzen? Wie könnte ein solches wirksames Lehrertraining aussehen?

Authors: Valderrama Penago Johanna Ximena , Sánchez Burbano Nathalia Andrea , Morales Rubio Luis Jorge
Published: April 2024

Introducción: la enfermedad por coronavirus 2019 (COVID-19) es la causante de la pandemia declarada desde marzo de 2020. Se ha demostrado el efecto neurotrópico del virus en estudios experimentales y en reportes de caso; sin embargo, pocos reportes de caso evalúan la neuropatía laríngea. Objetivo: describir la frecuencia de neuropatía laríngea en pacientes que han cursado con infección por SARS-CoV-2 atendidos en el Servicio de Otorrinolaringología-Laringología del Hospital Militar Central. Métodos: Se desarrolló un estudio observacional, descriptivo tipo serie de casos en los pacientes con neuropatía laríngea posterior a infección por SARS-CoV-2 que fueron manejados por el Servicio de Otorrinolaringología-Laringología desde el inicio de la pandemia. La recolección de datos se realizó a partir de la revisión de historias clínicas. Resultados: se presentan 20 pacientes con hallazgo de neuropatía laríngea posterior a infección por SARS-CoV-2, con un promedio de 53,9 ± 17,7 años, siendo el 55 % de sexo masculino. La aparición de parálisis o paresia de pliegues vocales se presentó en el 80 % de los pacientes con requerimiento de intubación endotraqueal (IET) durante la infección, y es más frecuente la parálisis bilateral de pliegues vocales seguidos de la parálisis unilateral. Conclusiones: la infección por SARS-CoV-2 genera una serie de afectaciones laríngeas, entre las que destaca la neuropatía. Pese a que sus mecanismos fisiopatológicos no están del todo explicados, diversos reportes de la literatura datan del compromiso de diversos pares craneales y del papel neurotrópico del virus.

Authors: Asensi Díaz Montserrat , Schilling Borghesi Andreas , Aguado del Hoyo Alejandra , Hernando Cuñado Mónica
Published: April 2024

Introducción: la hipoacusia de transmisión es la causa más común de pérdida de audición en la infancia. Dentro de sus posibles causas, la otitis media serosa (OMS) es la etiología más frecuente. Sin embargo, existen otras etiologías que pueden causarla. Caso: Presentamos tres casos de pacientes en seguimiento por hipoacusia de conducción con OMS asociada a otras patologías. Discusión: a pesar de ser mucho menos frecuente, las malformaciones congénitas del oído medio, así como el bulbo yugular alto, suponen una causa de hipoacusia conductiva en la infancia. Para lograr su diagnóstico se debe realizar una correcta anamnesis, otoscopia, audiometría, timpanometría y acumetría. Como pruebas complementarias, la tomografía computarizada y la resonancia magnética son de elección, y en ocasiones es necesaria la exploración quirúrgica. Conclusión: es importante realizar un correcto diagnóstico diferencial de la hipoacusia conductiva, teniendo en cuenta que es posible la coexistencia de varias causas en un mismo paciente.

Bu bağlamda sanayileşmede çevre dostu üretim uygulamaları desteklenmelidir. Türkiye’de ayrıca büyük şehirlerde çarpık kentleşme problemine çözüm sağlayacak uygulamalar yapılmalıdır.
Article 2 of Double Taxation Agreements and the Fate of Digital Service Taxes
Authors: Kara Mustafa Cemil
Published: April 2024

Article 2 of double taxation agreements (DTAs) is intended to ensure covered taxes under a DTA. Article 2 is significant since the legal protection provided by DTAs is limited only to the scope of DTAs. However, the wording of Article 2 may lead to confusion and uncertainty for taxpayers in terms of taxes within the scope of DTAs. In recent years, there has been a widespread trend of excluding digital service taxes (DSTs) from DTAs due to the lack of a global consensus on a common solution. This has refocused attention on Article 2. The fact that there is a scarcity of research on Article 2 raises concerns about what will happen if different types of taxes emerge over time. In this article, some important points and Türkiye’s approach related to Article 2 and Türkiye’s DST law which sometimes causes ambiguities and uncertainties for taxpayers were highlighted. This article also aimed to enhance a common understanding of the logic of the term "taxes covered." The research employed the descriptive research method, primarily utilizing the OECD Model Tax Convention (MTC) and its commentary, as well as prominent academic studies in the field and the Turkish DST law.

Cholinergic anti-inflammatory pathway confers protective effects in septic shock rats
Authors: Shen Yuchao , Cui Ying
Published: April 2024

Background: Septic shock can lead to multiple organ dysfunction. The cholinergic anti-inflammatory pathway is known to prevent organ damage from infection by modulating the inflammatory response. However, the modulatory capacity of cholinergic anti-inflammatory pathways in septic shock remains unclear.
Methods: Cecal ligation and puncture (CLP) was used to establish a rat model of septic shock. Bilateral cervical vagal nerve isolation, dual cervical vagotomy, and vagus nerve stimulation (VNS) were used to inhibit or activate cholinergic anti-inflammatory pathways. Tacrine and α-bungarotoxin groups were used to mimic the activation and shutdown of cholinergic anti-inflammatory pathways. The survival status, hemodynamic indicators, inflammatory cytokine content, and inflammatory response of liver and kidney tissues of the rats were detected.
Results: Dual cervical vagotomy significantly exacerbated the hepatic (p < 0.05) and renal (p < 0.05) impairment in septic shock rats relative to the sham-operated group. Tacrine, a cholinergic potentiator, significantly alleviated liver (p < 0.05) and kidney (p < 0.05) damage in septic shock rats. Dual cervical vagotomy significantly promoted the expression of pro-inflammatory factors caused by septic shock in rat liver and kidney tissues (p < 0.05), while Tacrine treatment inhibited the increase of inflammatory factors (p < 0.05).
Conclusions: Activation of the cholinergic anti-inflammatory pathway exerts protective effects on multiple organ dysfunction caused by septic shock. The cholinergic enhancer, Tacrine, and VNS effectively ameliorated liver and kidney damage, improved hemodynamic indicators, and enhanced survival rates in septic shock rats.

Land conflict poses a significant challenge to sustainable development and peace in many districts, including the Qardho district of Puntland state, Somalia. This paper explores the root causes, effects, and potential solutions to land conflict in the Qardho district. The study was guided by three objectives, which included, A) To assess the root causes of land conflict in the Qardho district, B) To investigate the effects of land conflict in the Qardho district, and C) To propose possible solutions to the land conflict in the Qardho district. A total of 399 interviews and ten key informant interviews were conducted to gather insights from various stakeholders, including local council members, land brokers, court judiciaries, and community groups. Quantitative and qualitative research designs were both used in this study. Significant demographic characteristics of the research respondents indicate that 51.88% were male and 48.12% were female. This data presents the distribution of respondents across different age groups. The majority of respondents (61.15%) fall within the age range of 31 to 40 years, indicating a significant presence of individuals in this demographic category. Additionally, a substantial proportion of respondents (15.54%) belong to the 21-30 age group. The remaining respondents are distributed across older age categories, with 10.78% aged 51-60 years, 7.52% above 60 years, and a smaller proportion (5.01%) falling within the 41-50 age range. Overall, the data reflects a diverse age composition among the respondents, with a notable concentration in the 31-40 age group. The findings reveal that private land ownership, lack of a land registration system, weak institutional capacity, and ineffective regulations are among the primary causes of land conflict in Qardho. These conflicts manifest in various adverse effects, including mistrust among communities, clan conflicts, hindrance to investment and development, and exacerbation of natural disasters' impacts. Respondents proposed several solutions to address land conflict, such as implementing a land registration system, strengthening government institutions, utilizing geographical information systems, and fostering cooperation between local government and courts. These findings provide valuable insights for policymakers, local authorities, and stakeholders to develop effective strategies for resolving land conflicts and promoting sustainable development in the Qardho district and similar contexts

Aim: Extracellular vesicles (EVs) have gained significant attention for their diagnostic and therapeutic potential in various diseases, including liver disorders. This study focuses on optimizing the isolation and characterization of small EVs from plasma and serum samples in patients with liver diseases, aiming to advance our understanding and potential clinical applications of EVs. Methods: Blood samples were collected from patients with end-stage liver disease (ESLD) enlisted in the TransplantLines Cohort and Biobank Study, and healthy donors. We employed differential ultracentrifugation (DUC) to evaluate three distinct protocols: a 3-step DUC, a washing step omitted [samples without washing (WW)], and a contaminant-depleted plasma (CDP) protocol. RNA isolation methodologies were compared, involving the use of TRI-reagent or the commercial AllPrep DNA/RNA kit. Further insights into EV composition were obtained through proteomic analyses, comparing samples subjected to traditional cell lysis (L) with those processed without lysis (NL). Results: We successfully isolated EVs from both plasma and serum samples as confirmed by the presence of specific EV markers, including CD9, CD63, CD81, and tumor susceptibility gene 101 (TSG-101). While some contaminants remained, such as albumin and lipoproteins, the protocol selected to continue EVs analysis was the 3-step protocol. Transmission electron microscopy (TEM) and nanotracking analysis (NTA) further confirmed EVs presence. RNA extraction was achieved using TRI-reagent, but not with the commercial kit highlighting the importance of selecting an appropriate method for RNA isolation. Finally, proteomics analysis showed that lysed samples were significantly more enriched in proteins compared to non-lysed samples, although protein variability was still present in both groups. Conclusions: Optimizing EV isolation techniques is essential for harnessing their potential in liver disease diagnosis and therapy. Further refinement of purification methods, a deep characterization of our cohort and understanding the variability and cargo within EVs will be crucial for future biomarker discovery and therapeutic applications in liver-related diseases.

Acute poisoning from a variety of substances is common in every part of the world. The sooner the initial resuscitation, decontamination, and use of specific antidotes, the better the outcome. The main objective of this study was to describe the clinical profile and outcome of poisoning cases admitted to SKIMS Medical college, a tertiary care hospital located in central part of Jammu and Kashmir India. Descriptive cross sectional evaluations were conducted on all cases that were admitted to the hospital’s emergency room over a period of one year from March 2022 to February 2023. The following parameters were examined using data taken from hospital medical records: socioeconomic factors, substances consumed, routes of intake, clinical symptomatology and severity of poisoning.300 patients were included in the study with different poisonings of which 35% were males and 65% were females. The most common form of poisoning was due to pesticides followed by rodenticides and opioid intoxication respectively. Majority of the patients had suicidal intent followed by accidental ingestion reported mainly in children. Few patient required intensive care admissions rest all were managed in general ward depicting mild severity of poisoning in majority of the patients. Three patients were brought dead to hospital secondary to opoid overdose and one patient died in hospital who had pesticide ingestion complicated by ventilator associated pneumonia. The less mortality in this study was likely due to mild severity of poisoning, early gut lavage and easy access to hospital. The effects of poisoning on the human body are negative regardless of the agents or method used and this has an impact on the treatment and outcome. Due consideration must be given to clinical, toxicological and epidemiological profiles. Therefore precise and prompt diagnosis, adequate treatment and effective preventative efforts are required. This study highlighted the importance of awareness and for the establishment of poison information centre for the better management and prevention of all poisoning cases.
