Authors: Lai Ruijun , Cheng Furong , Ye Tiancheng
Published: November 2024

Background: Myocardial ischemia is one of the most common postoperative complications in Cardiac surgery. Calcium channel blockers and nitroglycerin have some degree of protection against myocardial ischemia and are widely used in cardiac surgery. To compare the effects of calcium channel blockers and nitroglycerin on blood pressure, heart rate, and myocardial protection, a meta-analysis was conducted. Methods: The PubMed (Medline), Embase, and Cochrane Library databases were systematically searched, with the search period from database creation to April 2024. The study type was randomized controlled trial (RCT), and the comparisons were made between calcium channel blockers and nitroglycerin for myocardial protection during the perioperative period of cardiac surgery. Continuous variables were evaluated using the combined weighted mean difference (WMD) and 95% confidence interval (CI) or the risk ratio (RR) and 95% confidence interval. Results: A total of six randomized controlled trials (RCTs) were included, with a total of 608 patients. There was no statistically significant difference in postoperative systolic blood pressure between the two groups (WMD = 2.66, 95% CI: - 1.70 - 7.02, P = 0.23; heterogeneity test: P = 0.002, I2 = 70%). There was a statistically significant difference in postoperative heart rate (WMD = -2.53, 95% CI: -4.71 - -0.36, P = 0.02; heterogeneity test: P = 0.05, I2 = 52%). There was no statistically significant difference in the incidence of myocardial ischemia between the two groups (RR = 1.13, 95% CI: 0.88 - 1.45, P = 0.33; heterogeneity test: P = 0.96, I2 = 0%). Conclusion: The meta-analysis suggests that calcium channel blockers and nitroglycerin do not have a significant difference in their effects on myocardial protection, but the nitroglycerin group has a higher heart rate.

Authors: Song Wenxi , Tong Anqi , Chen Siyuan
Published: November 2024

The sex ratio of lampreys is subject to fluctuations influenced by external environmental factors, and alterations in this ratio may exert a significant impact on the stability of the surrounding ecosystem. To assess the position of lampreys within the food chain and comprehend the consequences of sex ratio variations on other species and ecological balance, this passage constructed an ecosystem dynamics model, a sex ratio variation model, and a logistic model. Additionally, this passage integrated food chain action factors and environmental variables for comprehensive analysis. The findings indicate that sex ratio fluctuations in lampreys have profound implications for their reproduction rate, population density, genetic diversity, and the overall stability of the ecosystem. If one sex significantly outnumbers the other, competition will increase and reproductive rates may decline. Resources can be overused, affecting the population as a whole. If the proportion of males in lampreys increases, the number of species they prey on May decrease, affecting the balance of the food chain. If the number of a particular sex is significantly too high or too low, it can lead to a reduction in genetic diversity, thereby increasing the genetic risk to the population. Our research contributes to a better understanding of the process of lampreys sex ratio change and provides a systematic analytical framework for predicting ecosystem dynamics, which can maintain ecosystem stability and improve the sustainable management and protection of the natural environment.
Study on the Influence of Lightweight Mechanical Structure on UAV Dynamic Response Characteristics and Control Strategy Optimization
Authors: Lu Shihao
Published: November 2024

In this paper, the influence of lightweight mechanical structure on the dynamic response characteristics and control strategy optimization of UAVS is deeply studied. With the wide application and rapid development of UAV technology, lightweight design has become one of the key technologies to improve the performance of UAV. Through the use of high-strength lightweight materials, structural optimization and advanced manufacturing processes, the weight of the UAV has been significantly reduced, thereby improving its load ratio, range and maneuverability. However, lightweight design also brings challenges such as reduced structural stiffness and increased vibration, and these changes have a profound impact on the dynamic response characteristics of UAVs. In order to comprehensively analyze the mechanism of the influence of lightweight mechanical structure on the dynamic response characteristics of UAVs, this paper firstly summarizes the key factors of lightweight design from three aspects: material selection, structure optimization and manufacturing process, and discusses how these factors affect the natural frequency, damping ratio, vibration mode and other key dynamic parameters of UAVs. Then, through theoretical analysis, the specific reasons for the change of UAV dynamic response characteristics caused by lightweight design are revealed, including vibration intensification and stability reduction. In order to deal with these challenges, on the one hand, an active vibration control system should be introduced to effectively suppress the vibration of UAVs during flight and improve flight stability through real-time monitoring and feedback control. On the other hand, adaptive control algorithm is needed to dynamically adjust control parameters according to the real-time flight status and environmental changes of the UAV, so as to improve the adaptability and robustness of the control system. The research results of this paper not only provide theoretical basis and practical guidance for the lightweight design of UAVs, but also provide new ideas and methods for the future development of UAVS technology.

Authors: Ye Xingyu
Published: November 2024

Real estate is an important industry in the national economy and plays an immeasurable role in the national and social life. However, with the rapid development of the real estate industry, in the real estate trading market, the situation of Yin-Yang contracts in the sale and purchase of second-hand houses continues to appear. The reason is that the government does not supervise the sale and purchase of the second-hand house, and the buyers and sellers in the transaction to reduce tax or defraud loans and other behaviors endanger the healthy development of real estate, resulting in major losses in national tax revenue. This paper aims to discuss how to solve the problem of Yin-Yang contracts through government supervision in practice, mainly including the legal effect of Yin-Yang contracts and tax evasion in the second-hand house transaction, and finally, through the continuous improvement of the government's supervision in the second-hand housing trading market to cope with and solve the problem of Yin and Yang contracts in the second-hand Housing trading market.

Authors: Wu Yiming
Published: November 2024

This paper focuses on the comparison of various numerical solutions for Initial Value Problem(IVP) and Boundary Value Problem(BVP) in differential equations. The practical problem is solved by comparing each numerical method solution. In the part of IVP problem, this paper established an Susceptible Infectious  Recovered Model (SIR) to measure the disease situation in India during the new coronavirus period of 2020-2021, and calculated the corresponding parameters through machine learning genetic algorithm(GA). The differential equations are solved by using first and second-order Taylor expansions(TM), Euler(EM), improved Euler(ME), Runge-Kutta 2(RK2), optional Runge-Kutta(RK2*), and Runge-Kutta 4(RK4) methods. Then, based on the model, the situation of the novel coronavirus epidemic in the next year is predicted; In the part of BVP problem, this paper establishes a linear spring model(LSM) to measure the displacement of elastomer under the force distribution, that is, the force density, by using a simulation algorithm(SA) to expand a small amount of measurement data, and by using machine learning algorithm linear regression(LR) to calculate the spring stiffness coefficient. Numerical solutions are calculated by using forward, center and backward finite difference method(FDM), Galerkin method in variational method(VGLM), collocation method(CM) and Galerkin method in finite element method(FEM), and mean square error(MSE) is used to evaluate the model. Finally, the analytical solutions especially Laplace Transformation(LT) of the two models are given to compare the numerical solutions.

Microfluidic Synthesis of Metal-Organic and Covalent Organic Frameworks: Techniques and Benefits
Authors: Pan Yankai
Published: November 2024

Microfluidic technology represents a significant advancement in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), offering rapid and continuous production with precise control over reaction conditions. Traditional methods for synthesizing these materials, such as hydrothermal and solvothermal techniques, often require several hours or days and can result in inconsistent particle sizes and crystallinity. In contrast, microfluidic approaches could enable faster synthesis, enhance crystallinity, and make particle size uniform within minutes. This technology could prevent channel clogging and improve mas, and heat transfer efficiency enabled the successful production of hierarchical structures and core-shell composites with superior stability and catalytic properties. Examples like the synthesis of HKUST-1, MOF-5, IRMOF-3, UiO-66, and advanced COF fibers demonstrate the versatility and scalability of microfluidic systems. These advancements suggest that microfluidic synthesis not only streamlines the production process but also opens new possibilities for scalable industrial applications, paving the way for innovative uses in catalysis, gas storage, and sensing.
Specchio Post-Moderno di Dorian Gray nell’era digitale
Authors: Guercio Laura
Published: November 2024

L’articolo intende illustrare la rilevanza contemporanea della sindrome di Dorian Gray nell’era digitale, dove l’idealizzazione dell’individuo e della comunità si intreccia con la cultura della cancellazione e la ricerca ossessiva di potere, prestigio e controllo. La tesi avanzata suggerisce che, senza escludere altre cause di natura economica, giuridica e politica, alla radice degli attuali disordini sociali, inclusi quelli di natura internazionale, vi sia un aumento dell’esasperazione narcisistica individuale, causata dalla mancanza di controllo, anche normativo, sulla dimensione digitale, i cui ritmi superano notevolmente le capacità umane di reazione. La tesi esplora tre dimensioni principali: la costruzione di un sé perfetto nel contesto digitale, la formazione di una comunità conforme a valori predefiniti tramite la cultura della cancellazione e, infine, l’analisi della ricerca ossessiva di prestigio e potere da parte degli attori statali. Esiste uno sviluppo consequenziale di questi tre aspetti, i quali sono interconnessi tra loro attraverso il filo conduttore di una moderna interpretazione della sindrome di Dorian Gray che si manifesta grazie all’acceleratore del digitale a ritmi non paralleli a quelli del mondo fisico. In altre parole, e questo è il punto che l’articolo intende analizzare, si tratta di capire se l’idealizzazione dell’io online, e i suoi effetti conseguenti a livello culturale, sociale e geopolitico, trovino un confronto paritario con i ritmi di reazione del mondo fisico. Oppure se quest’ultimo, con le sue regolamentazioni normative del secondo dopoguerra, sia ormai superato.

Published: November 2024

برامج تدريب المعلمين في تعليم اللغات عمومًا تهدف إلى مساعدة الطلاب الذين يدرسون ليصبحوا معلمين للغات أو حتى المعلمين غير المتمرسين على تطوير أسلوب تدريس أفضل. عادةً ما تنطوي مثل هذه البرامج على مراقبة المشاركين أثناء تدريسهم من قبل خبراء. سيقوم الخبراء في وقت لاحق بتوجيه المتدربين لتحقيق الهدف المذكور أعلاه من خلال تسجيل الملاحظات والتعليق فيما بعد على مزايا وعيوب الدرس أو على أداء المتدرب الذي يتم مراقبته بشكل عام. في الواقع، يجب على معلمي اللغات التخرج من مراكز تدريب المعلمين المكرسة فقط لتدريب المعلمين. ومع ذلك، في بعض البلدان، مثل البلد المشار إليه هنا - ليبيا، يتخرج معلمو اللغات من أقسام اللغة في كليات العلوم الإنسانية أو كليات التربية في الجامعات، وأحيانًا حتى من كليات الآداب والعلوم. نظرًا لعدم تخصص هذه الكليات في تدريب المعلمين، يكون النتيجة مشكوك فيها.
أصول الحكم عند عبد الحميد بن باديس
Authors: يونس عمر علي
Published: November 2024

تتناول هذه المقالة أصول الحكم عند عبد الحميد بن باديس، الزعيم الجزائري والمفكر الإسلامي في النصف الأول من القرن العشرين. يُعتبر بن باديس مصلحًا ورجلًا سياسيًا، وكان يعتمد في رؤيته على قيم دينية وعقائدية. حاول بن باديس تقديم دستور للأمة الجزائرية، يثبت فيه عدم مشروعية الحكم الفرنسي في الجزائر، مستندًا إلى خطاب الخليفة الأول أبي بكر الصديق. رأى بن باديس أن الحكم في الإسلام يجب أن يكون بموافقة الأمة، وأن الشعب هو الذي يمتلك الحق والسلطة في الولاية والعزل. كما أكد على حق شعوب الأمة في مراقبة ومحاسبة الحكام وعزلهم إذا استبدوا بظلمهم. يشترط بن باديس الكفاءة والقدرة في الحكم بدلاً من الخيرة المطلقة. يتأثر بن باديس بنظرة عبد الرحمن الكواكبي للاستبداد، حيث يرى أن الحكام الظالمين سبب تخلف الأمة، ويعز على أهل العلم مقاومة المستبدين وتعليم الجاهلين. يؤكد بن باديس أن الأمة لا تحكم إلا بالقانون الذي وضعته لنفسها، وأن الحكام ليسوا سوى منفذين لإرادة الأمة. يتأكد بن باديس من أهمية المبادئ الإسلامية في العدل والإنصاف، ويسعى لإحياء هذه المبادئ من خلال التفاعل مع مبادئ الثورة الفرنسية. على الرغم من عدم مشروعية الحكم الفرنسي في الجزائر، لم يكن بن باديس يستبعد العمل السياسي الداعي إلى الحقوق والتحرر والاستقلال. كان بن باديس أول من حدد فكرة الوطن الجزائري، وسعى لتحقيق الاستقلال والتحرر.

Background: Controlling blood glucose levels is crucial for optimizing outcomes in critically ill patients. While the sliding-scale insulin regimen is common, the efficacy of basal-bolus insulin therapy, using insulin glargine and insulin aspart, is less explored in critical care settings.

Objective: This study investigates the efficacy and safety of basal-bolus insulin therapy compared to sliding-scale insulin in managing hyperglycemia in critically ill patients in a medical intensive care unit (ICU).

Methods: The BASal-Bolus Insulin Therapy in Critically Ill Patients (BASIC) trial is a single-center, open-label randomized controlled trial at Srinagarind Hospital, Thailand. The study will enroll adult critically ill patients admitted to the medical ICU with capillary blood glucose (CBG) levels between 180 and 400 mg/dL. Participants will be randomized (1:1) to receive either basal-bolus insulin therapy or sliding-scale insulin (control). The primary endpoint is the percentage of CBG within the target range of 140–180 mg/dL. The secondary outcomes include daily mean CBG levels, glucose variability index, 28-day mortality, length of stay in the ICU, incidence of nosocomial infections, ventilator-free days within 28 days, and occurrences of hypoglycemia.

Hypothesis: Basal-bolus insulin regimen has a higher efficacy in glycemic control compared to a sliding-scale regimen in critically ill medical patients.

Discussion: Evidence regarding the effectiveness of the basal-bolus insulin regimen in critically ill patients is limited, with most existing studies focusing on non-critically ill populations. This study addresses this gap by comparing the basal-bolus approach to the conventional sliding-scale insulin regimen. This trial aims to provide valuable insights into optimizing glycemic control in critically ill patients, potentially leading to improved clinical outcomes.

Setiap individu memiliki role mode yang berbeda dalam belajar, seorang guru memiliki peran penting dalam mengenali dan memahami karakteristik gaya belajar siswanya. Tujuan pada penelitian ini untuk medeskripsikan pemahaman guru tentang gaya belajar siswa dan profil pembelajaran guru dalam memfasilitasi gaya belajar siswa di SDN 018 Pematang Manggis. Jenis penelitian ini merupakan penelitian kualitatif dengan pendekatan naturalistic inquiry. Hasil penelitian menunjukkan bahwa guru wali kelas I, II, IV dan V di SDN 018 Pematang Manggis secara teoritis sudah memahami gaya belajar siswa. Profil pembelajaran yang guru lakukan dalam mefasilitasi gaya belajar siswa sudah cukup baik, strategi penyampaian materi telah dipersiapkan sedemikian rupa demi kelancaran pembelajaran, namun masih perlu meningkatkan penggunaan metode belajar yang lebih bervasiasi dan penyediaan media pembelajaran yang relevan. Kendala guru dalam memfasilitasi gaya belajar siswa yaitu kesulitan memfasilitasi siswa dengan gaya belajar auditori, jarang menggunakan proyektor saat mengajar dan belum tentu semua siswa mampu memahami materi pelajaran. Adapun upaya yang dilakukan guru untuk memfasilitasi gaya belajar siswa yaitu disiplin waktu, memantau kemajuan belajar siswa, memastikan semua siswa mendapatkan kesempatan belajar yang sama, menjalin kerjasama antara siswa, guru dan ortu serta memperluas wawasan.

Objective: This study aimed to investigate the impact of thioacetamide (TAA) on the structure and function of the testes and assess the therapeutic effects of Curcuma longa (Cl) against TAA-induced toxicity in rats.
Materials and Methods: Thirty-two male albino rats weighing 180–200 gm and aged 11–12 weeks were randomly separated into four groups. The control group was given normal saline, the Cl group was orally administered Cl (500 mg/kg/day), the TAA group received intraperitoneal TAA (200 mg/kg body weight, three times/week), and the Cl with TAA group received Cl orally two hours before TAA administration. After 8 weeks, all rats were anesthetized, and body and testis weights were recorded. Morphological and histological assessments as well as biochemical analyses were conducted.
Results: The study revealed a significant decrease in both body and testis weights in the TAA group, accompanied by a substantial increase in luteinizing hormone (LH), follicle-stimulating hor¬mone (FSH), and malondialdehyde (MDA) levels. Testosterone (T) and glutathione (GSH) were significantly decreased in the TAA-treated group compared to the control. Conversely, the Cl-treated group exhibited a substantial decrease in LH, FSH, and MDA levels while showing a significant increase in T and GSH.
Conclusion: Cl has been found to have a potential therapeutic role in mitigating TAA-induced testicular damage by acting as an antioxidant. This is supported by a significant decrease in oxi¬dative stress markers and supporting hormonal levels. Further research is needed to understand the underlying mechanisms and explore the clinical applicability of Cl in preventing and treating testicular toxicity.

Objective: This study aimed to assess the welfare conditions of broiler chickens in the live bird markets (LBMs) in Bangladesh.
Materials and Methods: A total of fifty broiler outlets were studied in 10 LBMs of Chattogram, Bangladesh. A total of 10 chickens were observed to check the welfare issues during slaughter from each outlet (N = 500). The data were collected using a structured questionnaire method through interviews of the vendors and observation of the lairage and slaughter practice.
Results: The study revealed that the stocking density was significantly higher in cage-type lairage than in floor-type (p < 0.05). The feeding and drinking areas for the chickens were significantly but negatively correlated to the stocking density. The duration between unloading of broiler chickens at LBMs and feeding or drinking could exceed 5 hours in 22% of outlets. The mortality was significantly higher in the bigger outlets than the smaller outlets (p < 0.05). During pre-slaughter han¬dling, the one-wing grasping method was practiced more in the bigger outlets (p < 0.05) whereas the feet grasping method was used more in the smaller outlets (p < 0.05). Moreover, the knives used to slaughter the chickens were not sharpened daily in 76% of outlets.
Conclusion: This study indicated that the broiler chickens in the LBMs of Chattogram had to face many stress episodes at different stages at their penultimate moments—from lairage to slaugh¬ter—which led to poor welfare conditions and exacerbated the suffering of chickens.

Published: November 2024

Citation management software (CMS), especially Mendeley, has been suggested for researchers to automatically manage bibliographic information thanks to its complementary version with significant space for data storage. However, little research has been conducted regarding the applicability of Mendeley to the academic writing of postgraduates, especially in Vietnam. This study examined postgraduates’ perspectives toward utilizing Mendeley in academic writing during their language master’s programs at a public university in Vietnam using a mixed method. Data was collected through pre- and post-survey questionnaires of 45 postgraduates majoring in foreign languages and in-depth interviews for a thorough investigation. The findings indicated that Mendeley enhanced the participants’ research productivity and quality, but technological issues and a lack of training limit its use. Also, the study recommended that the institution organize workshops, seminars, and fundamental training courses in Mendeley for postgraduates to use it efficiently.

Authors: Jumaah Noora Saleem
Published: November 2024

Deep learning research has actively focused on object detection due to its importance for applications such as image and video interpretation. Object detection is an important issue in computer vision and has close-related applications such as surveillance and autonomous vehicles. This paper explores the use of You Only Look Once (YOLO), a state-of-the-art deep learning framework, to detect objects in animal images. As we all know, the YOLO model is known for its high speed and high accuracy, and it has been applied to applications that require real-time processing. In order to optimize the YOLO model for correctly classifying among the images of animals in the presence of people and images of just animals who are happy, sad and excited, images of cats and dogs in three states were made to the pre-trained CNN. From the experimental data, it can be confirmed that there some improvements of using more accurate YOLO versions for recognizing animal emotions, making the accuracy from 70% to 96%. The model was able to achieve a mean Average Precision (mAP) of 91%. The results highlight that the model is well positioned to improve urban safety and security through a highly effective approach to animal detection.

Indonesia telah mengalami beberapa kali perubahan kurikulum. Kurikulum Merdeka lahir dari respon pemerintah terhadap kondisi pandemi Covid-19 di Indonesia. Kurikulum Merdeka memiliki sejumlah karakteristik yang berbeda dengan kurikulum 2013. Perbedaan paling mendasar adalah pada perubahan penggunaan istilah Kompetensi Inti (KI) dan Kompetensi Dasar (KD) menjadi Capaian Pembelajaran (CP). Penelitian ini bertujuan untuk menganalisis ruang lingkup materi dan kompetensi yang termuat dalam Capaian Pembelajaran pada Kurikulum Merdeka khususnya pada materi pelajaran Biologi fase E dan fase F. Penelitian ini adalah penelitian kualitatif deskriptif dengan melakukan komparasi antara KD pada kurikulum 2013 dengan CP pada kurikulum merdeka. Teknik pengumpulan data dilakukan melalui analisa kepustakaan. Hasil analisa menunjukkan bahwa kurikulum merdeka pada mata pelajaran biologi memiliki lingkup materi yang sangat singkat dan padat jika dibandingkan dengan kurikulum 2013. Materi esensial ini menuntut inovasi dan kreativitas guru untuk menjalankan proses pembelajaran. Perubahan lain yang ditemukan yaitu peningkatan level kognitif pada kurikulum merdeka mata pelajaran Biologi.
