Al-Ḥasan al-Yūsī (d. 1102/1691) on Books, Knowledge Acquisition, and Manuscript Correction in the Seventeenth-Century Maghrib
Authors: Kraneiß Natalie
Published: December 2024

This article examines the practices of textual transmission and correction adopted by seventeenth-century Maghribī scholars, focusing on al-Ḥasan al-Yūsī (d. 1102/1691) and his comprehensive manual al-Qānūn fī aḥkām al-ʿilm wa-aḥkām al-ʿālim wa-aḥkām al-mutaʿallim (The Canon on the Principles of Knowledge and the Rules for the Scholar and the Student). In this work, al-Yūsī reflects on the importance of books in the acquisition and transmission of knowledge, outlines the conditions under which it is permissible to extract knowledge directly from books and argues for the application of strategies of textual criticism developed by ḥadīth scholars. This study examines al-Yūsī’s views on these practices and the role they played in rural Sufi lodges in the Western Maghrib. Examples from the library of the Sufi brotherhood Nāṣiriyya in Tamgrūt, with which al-Yūsī was closely associated, illustrate how these theoretical principles were put into practice. By shedding light on these practices, the article contributes to our understanding of scholarly methods in early modern Islamic intellectual history.
Intersemiotic Translations of Greek Popular Films in the Film Industry and Media
Authors: Kourdis Evangelos
Published: December 2024

This paper examines cultural texts and their place in the Greek semiosphere. More particularly, it delves into intersemiotic translations or adaptations or remakes of masterpieces of, the so-called, Golden Age of Greek cinema, which are deeply engraved in the Greek collective cultural memory. These cultural texts assume yet further value many decades after they were created, through three semiotic choices involving a translational dimension: their colourisation, their cinematic adaptation, and their amateur remakes hosted on social media and other internet sites. Assuming that the original texts are located at the centre of the Greek semiosphere, this study aims to show whether these new texts, the metatexts, are placed next to their originals or whether they coexist along the periphery or near the borders of the Greek semiosphere, an element that will determine the extent to which they will be accepted by contemporary Greeks. The study shows that the popularity of new cultural texts, which belong to the comedy genre, is increasing due to the desire of film audiences to participate through these intersemiotic translations (metatexts) in the popularity of the original cultural texts (prototexts) that are considered cultural myths.
“A Literature of Frustration and Failure”: The Anxiety of Indianness in the Making of Sindhi Literature as an Indian Literature
Authors: Wadhwa Soni
Published: December 2024

Studies of Partition frequently turn to literature to understand how displacement processes, among other things, impact aesthetics and representation. This article takes a broader view of aesthetics as representation: it demonstrates how turning to the literary archive of a moment and a community gives rise to questions about the politics of individual texts and literary historiography. Centered on Sindhi literature produced in India after Partition, it shows that examining the literary productivity of the community needs to involve questions of literature as political survival. It focuses on the earliest essays from the Sindhi literary scene in India (published in the Sahitya Akademi journal Indian Literature). The article argues that these essays register anxiety about the survival of a language trying to come into being in an already existing and complicated language-nation relationship. It unpacks three registers of anxiety visible in the literary archive to broaden the scope of the conversations around the Sindhi language and its literature.

The Spotted Litter Skink, Sphenomorphus maculatus, initially described by Edward Blyth in 1854, lacks a taxonomic reference point, as the holotype was reported lost by 1868. A preliminary molecular phylogenetic analysis revealed indications of cryptic diversity within S. maculatus across its range in Northeast India. We aimed to pinpoint the precise type locality, concluding that it corresponds to the peripheral forested regions surrounding Guwahati, India. To establish a robust taxonomic foundation for future investigations, we designate a neotype under the provisions of the ICZN Code (Article 75). We also provide a comprehensive redescription of the neotype. This analysis and redescription were based on recently collected specimens from the identified type locality, and approximate areas based on the movements of Col. Jenkins, who was the original collector of the holotype. Genetic data from six loci of the neotype and from the other specimens were deposited in GenBank, contributing valuable information for future reference.

Palm oil is widely consumed in Côte d'Ivoire and is accused of causing hypercholesterolemia, which justifies the evaluation of the impact of its consumption on the increase in total cholesterol in Ivorian people. This was a prospective cross-sectional analytical study involving 2862 palm oil consumers over a 11-month period. The study was carried out in the health districts of Côte d'Ivoire and in the medical biochemistry laboratory from medical Teaching School. The majority of subjects in this study consumed palm oil i.e. 98.8% of the 2862 surveyed. A lipid profile was performed: total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol in these subjects. Female are predominant (51.1%) and the mean age was 39.75 ± 14.31 years. Palm oil consumption was reported by 82.9% of individuals with hypercholesterolemia and 85.0% of those without hypercholesterolemia, showing no significant difference (p = 0.720) They had a mean total cholesterol level of 1.8±0.5 g/L and an atherogenicity index of 4.3±1.6. However, there was no significant correlation with the quantity of palm oil consumed. In this dataset, palm oil consumption does not appear to be a significant predictor of hypercholesterolemia in the Ivorian population. Overall, although no statistically significant association was found between palm oil consumption and hypercholesterolemia, it is essential to consider other potential factors that may affect cholesterol levels. Given its beneficial biochemical properties and various health benefits, regular consumption of this oil should still be encouraged.

Published: December 2024

A collapse of bee colonies, for the first time in Morocco, of unknown origin, was announced on January 21, 2022 by the National Office for Food Safety (ONSSA). Causes were mentioned such as the unprecedented drought affecting the country and climate change as well as the use of pesticides and the appearance of new hive parasites and viruses. Colony collapse disorder (CCD) has been reported in several parts of the world, including Europe, Canada and Asia. Due to the agro-economic and ecological interest of the bee in the pollination of fruit trees and various seasonal and annual crops, the condition is considered alarming. Hence the need for an integrated control program that uses various monitoring measures and a set of mechanical, physical, biological and chemical control methods against hive pests. A census of the observation and countermeasures of Morocco and at the level of the world in the face of this problem was carried out. Viral diseases (Dicistroviridae in the United States) or parasites (in Spain, the fungus Nosema cerenae, varroa destructor in Canada, Varroa, itself vector of the virus), livestock management problems (transhumance and inbreeding) and the use of pesticides (the Gaucho, banned on sunflower since 1999 in France) remain the most studied causes. Surveillance and vigilance networks for beekeepers whose objective is to continuously inform the beekeeping sector of the general state of health of bees (mortality, theft of hives, invasions by other insects and parasites, etc.) everywhere in the world are essential. The ApiVigi® network is an example.
Yield Components and Yield of Common Bean (Phaseolus vulgaris L.) Varieties as Influenced by Rates of Phosphorus at Yabello, Southern Oromia, Ethiopia
Authors: Olika Gutema , Ayana Demisachow , Daba Nano
Published: December 2024

Common bean is one of the economically most important legume crops grown in Ethiopia. One of the main factors limiting the productivity of common beans in the southern region of Oromia is poor soil fertility. The study was carried out to determine the effect of phosphorus fertilizer rates on common bean growth and production as well as to pinpoint commercially viable treatments that can increase common bean productivity. Three common bean varieties (Hawasa dume, Ado, and Batu) and five phosphorus levels (0, 23, 46, 69, and 92 kg P ha-1) were arranged in a factorial combination design with three replications in an RCBD. The study's findings indicated that the main effects of common bean varieties and phosphorus application rates were considerably influenced days to 50% flowering, days to maturity, plant height, and number of primary branches per plant. However, only the primary effect of P rates had a substantial effect on the harvest index. On the other hand, the interaction effect of phosphorus fertilizer rates and common bean varieties had a significant impact on the number of seeds per pod, number of pods per plant, total number of nodules per plant, total number of effective nodules per plant, hundred seed weight, grain yield, and aboveground biomass yield. The Hawasa dume variety, at 69 kg P ha-1, had the highest seed yield (2777.10 kg ha-1), whereas the Batu variety, without P application, had the lowest seed yield (1,718.73 kg ha-1). Additionally, correlation analysis demonstrated a positive and substantial relationship between seed yield and the majority of yield-related traits. The application of phosphorus fertilizer at 46 kg P ha-1 resulted in the maximum net benefit (120,856 ETB ha-1) and MRR (1144.44 %) according to economic analysis. According to this study, applying phosphorus fertilizer may help promote high nodulation, yield, and growth of common beans. Thus, it can be said that for common production in the Yabello district, the application of phosphorus fertilizer at 46 kg Pha-1 is advised. To get a final suggestion, it is advisable to repeat the experiment throughout several seasons and places, as it was only carried out for one season at a single location.
Calculation of the Initial 53Mn/55Mn in Calcium-Aluminum Rich Inclusions in the Solar Wind Implantation Model
Authors: Bricker Glynn
Published: December 2024

Studies indicate that short-lived radionuclides (SLRs), including 53Mn, were incorporated into Calcium-Aluminum Rich inclusions (CAIs) in ancient undisturbed primitive meteorites at the time the solar system was forming. In this study, the potential incorporation of 53Mn into CAIs in accordance with the Solar Wind Implantation Model (SWIM) is investigated. In the SWIM model, radiogenic nuclei are made through solar energetic particle (SEP) nuclear reactions with target material in the proto-stellar atmospheres of proto-stars are whilst the proto-stars are in the accretion phase. The newly produced daughter nuclei are subsequently trapped in the magnetic field lines associated with the proto-stars. The radiogenic nuclei are then funneled into the X-region, and some fraction of these nascent nuclei are implanted into refractory matter which accretes towards the proto-star. Production rates daughter nuclei scale with ancient X-ray luminosities, which have been measured to be 100,000 times contemporary levels in T Tauri stars, yielding daughter nuclei produced at ~105 over contemporary levels. From the ancient enhanced SEP fluxes and refractory mass inflow rate found in the SWIM, we found the initial 53Mn/55Mn isotopic ratio ranged from 4 x 10-5 to 6 x 10-4, when taking into account spectral flare variability.

Published: December 2024

Anxiety, specifically in situations involving speaking, is characterized as a type of fear that manifests through observable symptoms. Public Speaking Anxiety is a prevalent issue among students during classroom presentations, affecting their confidence and performance. Despite its significance, there remains a lack of comprehensive understanding regarding the specific factors that contribute to this form of anxiety in educational settings. From these observations, it's apparent that not all individuals possess the same speaking and presentation skills. While some may excel as confident speakers, others might experience speaking anxiety, especially when addressing large audiences or during classroom presentations. Hence, the researcher intends to assess the factors contributing to students' public speaking anxiety specifically during classroom presentations. The objectives of this study are to assess to the major contributing factors for student speaking anxiety in classroom presentation. This study was conducted in Bonga University, particularly in college of educational and behavioral sciences in 4th year psychology students.

Published: December 2024

Although finger millet is grown extensively in Ethiopia, the national average yield is much less than the crop's genetic potential. This is due to a lack of stable, high-yielding, and disease-tolerant finger millet varieties. Thus, the current study was conducted to find stable, high-yielding, and disease-tolerant genotypes for increasing production. A randomized complete block design was used to evaluate twelve finger millet genotypes under a regional variety trial at Mechara and Habro for three consecutive years (2017 to 2019) against standard checks (Maba, Addis01, and Axum). The tested genotypes were brought from the Melkasa Agricultural Research Center. Further, some of these genotypes were collected from different areas of Oromia and the remaining were introduced from Kenya including Ikulule through Melkasa Agricultural Research Center. At the multi-environment evaluation, the yield advantage of the new variety is 18% higher than the best-performed standard check Maba (5.8tha-1). Additionally, the GGE biplot analysis showed that the Ikulule variety is high-yielding across locations and years. Also at the variety verification trial, the overall mean grain yield of (Ikulule) at on station and farmers' fields is 3.81 t tha-1 whereas the standard check kumusa is 2.91 tha-1. The new variety is not only high-yield but also resistant to blast rust and shoot flies relative to standard check. As a result, this new variety of Ikulule was released for the west Hararghe zone districts and similar agroecologies.

Authors: Sadigova Tora
Published: December 2024

Background: The cardiotoxic effects of anti-tumor therapies represent a critical concern in oncology, as they compromise patient survival and quality of life by inducing cardiovascular diseases. With an increasing number of cancer patients undergoing treatments such as chemotherapy and radiation, the incidence of cardiotoxicity has surged. These adverse effects underscore the necessity of early detection, risk stratification, and preventive strategies tailored to mitigate cardiotoxicity and improve patient outcomes. Objective: This meta-analysis aims to systematically evaluate the effectiveness of various interventions designed to prevent or reduce cardiotoxicity associated with anti-tumor therapies. By synthesizing evidence from existing studies, we seek to identify the most effective measures, providing a comprehensive overview of the current landscape in cardioprotective strategies. Methods: We conducted a comprehensive literature search, including peer-reviewed studies that investigated preventive strategies for cardiotoxicity in patients undergoing anti-tumor therapy. Inclusion criteria were studies evaluating pharmacological and non-pharmacological interventions and their effects on cardiac function and patient outcomes. Data were extracted and analyzed to assess the impact of interventions on cardiotoxicity incidence, cardiac biomarkers, and clinical endpoints. Main Findings: Our analysis demonstrates a range of effective cardioprotective interventions, particularly focusing on beta-blockers, ACE inhibitors, and lifestyle modifications. Beta-blockers were found to reduce the incidence of left ventricular dysfunction, while ACE inhibitors showed promise in improving cardiac biomarkers. Additionally, lifestyle interventions, including exercise and dietary modifications, contributed to overall cardiovascular health, though further research is needed to define optimal protocols. Conclusion: Preventive strategies play a pivotal role in managing cardiotoxicity in cancer patients undergoing anti-tumor therapies. Pharmacological interventions, especially beta-blockers and ACE inhibitors, show significant potential in mitigating cardiac damage, while lifestyle interventions offer supplementary benefits. Our findings underscore the importance of an integrative approach, combining pharmacological and lifestyle modifications to protect cardiac function.

Authors: Vashishtha Shwet
Published: December 2024

Proficiency testing (PT) plays a vital role in the plywood manufacturing industry, acting as a quality assurance tool to maintain high standards in product consistency and reliability. This study evaluates the effectiveness of PT in identifying and addressing quality issues within plywood production, focusing on three main objectives: assessing PT’s role in uncovering quality problems, analyzing root causes, and proposing targeted solutions for process improvement. The research involved eight laboratories evaluating the Modulus of Rupture (MoR) and Modulus of Elasticity (MoE) of plywood samples, with results statistically analyzed to measure inter-laboratory consistency and identify performance gaps. To ensure reliable testing, the PT samples were prepared in line with IS 303:1989 standards, emphasizing homogeneity and stability. Statistical analyses revealed variability among laboratories, highlighting areas for improvement in material handling and testing protocols. The study found that PT is instrumental for the industry, not only in identifying discrepancies but also in fostering a culture of continuous quality enhancement. Recommendations for improvement include refining the adhesive application, optimizing pressing parameters, ensuring accurate layer alignment, and implementing thorough end-of-line inspections. Quality control measures such as random sampling, supplier audits, and traceability systems are also recommended to maintain consistency. The study advocates for comprehensive employee training and cross-functional collaboration across production, quality assurance, and R&D teams to enhance overall product quality. By addressing critical process variables and leveraging PT as a benchmarking tool, plywood manufacturers can meet regulatory standards and customer expectations. This research underscores the importance of PT in delivering actionable insights for improving product quality and reliability, ultimately supporting the industry’s growth and commitment to safe, high-quality plywood products.
Experimental and Numerical Investigation of Buckling Behaviour in Q690 High-Strength Steel Tubes Under Combined Axial Compression and Bending Loads
Authors: Rajib Shek , Chen Lei
Published: December 2024

This paper investigates the buckling behavior of Q690 high-strength steel tubes under combined axial compression and bending loads through experimental testing and finite element analysis (FEA). A total of 27 full-scale specimens with varying slenderness ratios (λ) and diameter-to-thickness (D/t) ratios were tested to evaluate their load-bearing capacity, deformation characteristics, and failure modes. The experimental setup replicated real-world conditions, with constant axial loads applied alongside incremental bending moments until failure occurred. FEA models, developed using ABAQUS, incorporated geometric imperfections and material nonlinearities to simulate realistic structural behavior and predict critical buckling moments. The comparison between experimental and numerical results showed strong agreement, with deviations ranging from 5.6% to 7.9%, confirming the reliability of the simulations. The findings indicate that tubes with higher D/t ratios are more sensitive to imperfections, experiencing significant reductions in post-buckling moment capacity, while those with lower D/t ratios demonstrated greater resistance to buckling and maintained higher structural integrity. The transition between global and local buckling modes was effectively captured by both experimental and numerical approaches, validating the robustness of the models. This study emphasizes the importance of accounting for geometric imperfections and residual stresses in design practices to ensure the safety and reliability of high-strength steel structures under combined loading conditions. Additionally, the results underscore the effectiveness of advanced FEA tools in predicting structural behavior, providing valuable insights for improving design codes and practices. Future research is recommended to explore dynamic loading scenarios, such as wind or seismic effects, to further enhance the applicability of Q690 steel tubes in critical infrastructure projects.
The Impact of AI on Healthcare Jobs: Will Automation Replace Doctors
Authors: Sharma Manisha
Published: December 2024

The integration of artificial intelligence (AI) into healthcare has sparked considerable debate regarding its impact on the workforce, particularly concerning the roles of healthcare professionals such as doctors. This article explores the potential for AI-driven automation to replace certain medical tasks traditionally performed by physicians, as well as the broader implications for employment in the healthcare sector. While AI has demonstrated significant capabilities in areas like diagnostics, data analysis, and even surgical assistance, its role is largely seen as complementary rather than substitutive. Many experts argue that AI will enhance the efficiency and accuracy of medical practices rather than eliminate the need for human doctors. Moreover, the implementation of AI in healthcare is expected to create new roles focused on managing, interpreting, and improving AI systems, thereby shifting the nature of healthcare jobs rather than reducing their number. However, concerns about the potential for job displacement and the need for reskilling within the medical profession remain. This article concludes that while AI will inevitably alter the landscape of healthcare employment, it is unlikely to replace doctors entirely. Instead, it will transform the profession, requiring a new set of skills and a reimagining of the doctor-patient relationship.

Published: December 2024

Nowadays, one of the major problems facing large cities is the adaptation of energy needs with their rapid demographic growth. In most cases, there is a disconnect between the rapid demographic increases and the updating of energy needs. The major cities of the Republic of Guinea are confronted to a significant challenge due to insufficient energy supply for their sustainable development, and the urban commune of N’zérékoré is a clear example of this. The city is experiencing substantial rapid demographic growth, which requires a long-term assessment of its energy needs for its sustainable development. In this paper, a model for projecting energy demand over 10 years for the urban commune of N'zérékoré taking into account its demographic evolution was developed. An estimate of energy needs was made based on the projected population growth from 2024 to 2060. The results show that the urban commune's current energy consumption is estimated at 53.89 MW, or 38.8 GWh per month, while the projected energy demand for the same year amounts to 51.6 GWh. Population growth continuously drives a strong increase in energy demand, if production remains unchanged, by 2060 the commune’s energy need would reach 1,595.16 GWh, resulting in a deficit of 1,543.56 GWh.

Published: December 2024

This study examines the profound impact of climate change on socio-economic conditions in Beledweyne District, Hirshabelle State, Somalia. Using a descriptive research design, data were gathered from 123 stakeholders, including community leaders, representatives from non-governmental organizations, and internally displaced persons, through semi-structured questionnaires. Data were collected using structured questionnaires and analyzed using Structural Equation Modeling (SEM) with SmartPLS software and Excel for Demographic characteristics. The reliability and validity of the measurement instruments were confirmed through metrics such as Cronbach's Alpha, composite reliability, and Average Variance Extracted (AVE). The findings reveal that climate change intensifies existing vulnerabilities, primarily through recurrent flooding and prolonged droughts, which diminish agricultural productivity, compromise critical infrastructure, and drive population displacement. Specifically, the results indicate substantial declines in crop yields and livestock production, extensive infrastructure damage including roads and community facilities—and rising migration as livelihoods erode. These shifts have deepened poverty, increased food insecurity, and strained social cohesion, highlighting an urgent need for targeted resilience strategies. This study provides valuable insights for policymakers and development practitioners, emphasizing the importance of climate-resilient infrastructure, adaptive agricultural practices, and robust social safety nets as mitigative measures against climate-induced socio-economic degradation. These findings offer a foundation for formulating strategic interventions to enhance resilience in Beledweyne and similarly vulnerable regions.

Methods: This study was a cross-sectional survey design, using convenience sampling method to survey women of childbearing age who were followed up in the postpartum outpatient clinic of a tertiary hospital from August 2023 to March 2024, and the survey instrument included a general information questionnaire, a questionnaire on the willingness to reproduce, and an impact of event scale- Revised, which was statistically analyzed using SPSS 27.0, and a binary logistic regression model was used to analyze the influencing factors of reproduction intention, and P<0.05 was taken as statistically different. Results: Reproduction intention of women of childbearing age accounted for 42.9%, and age, education, residence, and PTSD were independent influencing factors of reproduction intention of women of childbearing age. Conclusion: The research results show that age, education level, place of residence and PTSD are independent factors influencing women's willingness to have children again. The higher the level of PTSD, the lower the willingness to have children again. Therefore, attention should be paid to women's postpartum mental health problems, and more family and social support should be provided to improve their mental health status, so as to enhance the level of willingness to have children again.

Published: December 2024

In academic research, bias refers to a type of systematic error that can distort measurements and/or affect investigations and their results. Biases can be present in both quantitative and qualitative research. The common effect of biases is undermining the power of statistical tests, therefore findings induced to support H0 hypothesis. Corrections depend on nature of bias and aimed to recover magnitude of association. Corrections use analytical constructs therefore applied in data analysis stage. Considered in the paper is of novel type and tentatively named inertia bias. This bias is of directed uncertainty about true value of index. One can find it in the range of designs and measures. The essence is the exposure takes time to shift index to new equilibrium. The problem is that researcher usually unaware of time required for index to settle down at new equilibrium. Therefore one inevitably measures the transition states instead of equilibrium yielding different magnitudes of attenuated association. How to obtain measure equilibrium value is the focus of the paper. Given the dynamical setup I referred to first order nonlinear differential equations, in particular logistic differential equation that meats necessary prerequisites: it should be separable equation, it has to have stable state, solutions have to descend or ascend toward equilibrium with the tangency in time. This paper describes range of circumstances where researcher faces the problem along with suggested solution, calculus, and tested software.

Introduction: The Anterior Lateral thigh flap (ALT) free flap can be considered one of the reconstructive tools in lower leg and foot reconstruction. It has a long and reliable pedicle, and dissection is comparatively easy, which makes it extremely suitable as a free flap. This study aimed to evaluate the versatility of the flap in covering lower leg and foot defects. Methods: This was a prospective observational study conducted in the Department of Plastic Surgery, Rangpur Medical College Hospital, Rangpur, Bangladesh, from January 2023 to December 2023. In our study, we included 16 patients with defects in the lower leg and foot who received an ALT-free flap as a reconstructive treatment. We analyzed the preoperative, intraoperative, and postoperative variables of our respondents. Results: In this study, 16 patients (12 males and 4 females) with an average of 34.25 years old were included. Among them 13 were traumatic cases, 2 electrical burn wounds, and one oncologic case. Survival rates of the free flap were 87.5% (14) with two failure cases. There were no complications at the donor site. In this study, 75% (12) cases showed excellent outcomes where there were no signs, or symptoms of venous congestion or arterial insufficiency, no infection or dehiscence, and the donor site was primarily closed with good flap adhesion. Conclusion: This study shows that the ALT-free flap is a versatile flap that allows it to cover the defect successfully and ALT adaptation was satisfactory in terms of varied location and size.
Monitoring and Eliminating Pre-Analytic Laboratory Errors in an Acute Care Setup - A Case Study

Published: December 2024

Laboratory investigations are an integral part of patient management. The number and frequency of investigations are directly related to the clinical seriousness of a patient. Hence acute care setups observe a high volume as well as frequency of sampling for laboratory analyses. Many management plans are dependent on the results of these investigations. So, there is also pressure on the pathology laboratory to provide the results as early as possible. The whole process of lab investigation requires ordering an investigation, sending the requisition/system indenture, sampling, transporting sample to the lab, analysing, result approval and sending/uploading the report. Well-planned, tried, and tested standards/ protocols must be in place in order to eliminate the probability of errors in investigation reports. Laboratories must work according to some set specifications in order to process the samples in an error free manner. This paper will analyse the procedural steps, scope of errors and steps to identify, report as well as rectify the errors in the pre-analytical phase of laboratory investigations in a highly demanding and accident-prone acute care setup. The aim of this exercise is to improve the quality of lab reporting process with an objective to eliminate pre analytic laboratory errors.

Explore the effect of Snyder hope theory nursing combined with adaptive cognitive emotion regulation strategy on hope level, psychological elasticity, response and negative emotion regulation ability of cirrhotic patients with esophagogastric variceal bleeding. 120 patients with liver cirrhosis with esophagogastric variceal bleeding from January to December 2023 were randomly divided into observation group (n = 60) and control group (n = 60). The control group was given the strategy of adaptive cognitive emotion regulation. The observation group was given hope theory nursing combined with adaptive cognitive emotion regulation strategy. After nursing, the scores of Herth hope scale (C-HHI), psychological resilience scale (CD-RISC), face dimension, avoidance and surrender in the observation group were higher than those in the control group (P < 0.05, 0.05). The scores of negative emotion regulation scale (NMR-S) in the observation group were higher than those in the control group. Snyder hopes that theoretical nursing combined with adaptive cognitive emotion regulation strategy can improve the hope level of cirrhotic patients with esophagogastric variceal bleeding, improve their psychological resilience and coping style, and improve their negative emotion regulation ability.
Thermal Vacuum Synthesis: Physical Processes in Nanomaterial Production
Authors: Kutovyi Volodymyr
Published: December 2024

The thermovacuum process offers an efficient and cost-effective method for producing nanomaterials by ensuring the continuous flow of dispersed material inside a spiral heating element. This is achieved by introducing the material into the heating element's cavity along with air, forming a two-phase gas-solid particle system. The material moves upward through the heated space, where pressure gradually decreases. Experimental studies on materials like carbon, brown coal, and zirconium dioxide indicate specific conditions are necessary for the system's continuous operation. One key requirement is that the mass of solid particles should not exceed 1.0 to 1.2 grams per liter of air entering the heating element. This limit ensures that nanodispersed and finely dispersed particles can move freely, avoiding collisions and allowing faster-moving particles to overtake slower ones. These particles increase in velocity and temperature as they pass through the heating element, with changes in heat capacity and particle motion contributing to wave motion and pulsed heat loads. The velocity at which the material particles travel depends on the thermal radiation from the heater walls and the energy generated by local pulse steam explosions, which create shock waves. Higher explosion energy results in increased particle velocity, greater impact angles against the heater walls, and higher environmental temperatures. These conditions lead to accelerated electron, proton, and other charged particle flows, forming plasma clots and neutrino clouds. The nanoparticles take various forms, including nanotubes, fullerenes, thin films, and crystals, reaching velocities up to a thousand kilometers per second and heating temperatures of up to 17 million degrees during pulses. This process consistently subjects the material to force, heat, deformation, and ionization, expediting the creation of nanodispersed materials with enhanced physicochemical and mechanical properties. The thermovacuum process not only improves the efficiency of thermotechnological equipment but also reduces energy consumption, production time, and costs. The research findings support its use in the continuous and effective production of high-quality nanomaterials.
