Experimental and Numerical Analysis of SMC Compression Molding in Confined Regions—A Comparison of Simulation Approaches

The compression molding process of sheet molding compound (SMC) is an economical manufacturing process for lightweight parts. However, molding defects, such as fiber matrix separation, and fiber re-orientation, may develop during the molding process in confined regions, such as ribs and bosses. Hence, the mechanical properties of the composite depend on the local fiber architecture. Consequently, this work compares the predictive capabilities of tensor-based and directly modeled process simulation approaches regarding compression force, fiber volume content and fiber orientation on the example of honeycomb structures molded from SMC. The results are validated by micro-computed tomography and thermal gravimetric analysis. The fiber orientation in the honeycomb varies between individual samples because a sheet molding compound is macroscopically heterogeneous and thus the fiber architecture is strongly influenced by random events. Tensor-based fiber orientation models can not reliably predict fiber volume content and fiber orientation in the part’s thickness direction if there is a lack of scale separation. Therefore, directly modeled process simulations should be preferred in cases in which fiber length and mold dimensions prohibit scale separation. The prediction of fiber volume content is a difficult task and no simulation can predict the severity of fiber matrix separation precisely in all cases.
The Role Of Job Satisfaction Mediation Variables On The Performance

The hospitality industry is facing a series of formidable challenges today. Some of these are relatively new, such as the rise in digital commerce, the increasing influence of mobile and social media, and the general decline in brand loyalty. In today's globalization challenges such as growing market opportunities, pressure on shareholders for short term results, continued lack of guest trust, and lack of talented employees. This research was conducted with a sample of 347 budget hotel employees from several budget hotel groups in the Jakarta area. The quantitative research method using SEM with the SmartPLS 3.0 tool used in this study aims to predict path analysis between constructs. Job satisfaction is also an important factor in hotel budgets because several factors that affect employee performance have a significant influence if mediated by job satisfaction. Leaders in the hospitality industry can increase employee job satisfaction by providing different motivators for employees at work and therefore managers should also pay more attention to job aspects related to job satisfaction
Is Dual Mobility Total Hip Arthroplasty Surgery More Aggressive than Hemiarthroplasty when Treating Femoral Neck Fracture in the Elderly? A Multicentric Retrospective Study on 302 Hips

Introduction Bipolar hemiarthroplasty (BHA) and total hip arthroplasty (THA) are validated treatments for displaced femoral neck fractures (DFNFs). BHA seldomly needs conversion to THA, but the latter has higher dislocation rate in FNFs. Dual Mobility THA offers a reduced dislocation rate and eliminates the risk of conversion. This study looks for differences between BHA and DMTHA in terms of surgical time, blood loss and transfusion, dislocation rate, mortality, and thromboembolic events. Material and Methods All patients were ≥75yo. Recorded data included use of anticoagulant/antiplatelet drugs, ASA, operative time, intra-operative complications, pre/post-operative hemoglobin values, transfusions, hospitalization time, DVT/PE, glomerular filtration rate, Charlson Comorbidity Index (CCI), dislocation at 60 days, and mortality at 30 days and 6 months. A secondary analysis compared the subgroups in different age range (75–85 and ≥ 86yo). Results In the cohort of 302 DFNF (93 BHA and 209 DMTHA) differences in mean age, CCI, and ASA score were significant. Once divided by age, the subgroups resulted comparable in terms of age and CCI, with no significant difference. A significant difference in surgical times showed DMTHA being an average 12 minutes longer than BHA. Significant was the ΔHB in the DMTHA subgroup which resulted lower compared to the BHA one. Difference in mean number of post-operative transfusion were not statistically significant. Conclusions From our data, DMTHA did not lead to an increase in mortality, morbidity, bleeding, or dislocation rate when compared to BHA and could be considered as treatment of choice for DFNFs especially in healthy and active patients.
Impact of Tax Incentives on Foreign Direct Investment Flow in Nigeria

© 2022 The Authors. This article is licensed under a Creative Commons Attribution 4.0 License Abstract. The growing pace of the globalisation process has triggered economic development, especially among developing nations. One of the immediate responses to this phenomenon is the increasing trend of Foreign Direct Investment flows among countries driven by some factors. This paper aimed at determining the impact of tax incentives (tax holiday and custom duty exemption) on Foreign Direct Investment inflow into Nigeria over the period 2008-2018. Using secondary data obtained from the Nigerian Investment Promotion Commission, Central Bank of Nigeria and Nigerian Customs Service, Driscoll-Kraay Standard Errors regression analysis was used via STATA version 14 to test the research hypothesis. The study's findings revealed that tax incentive has a positive and significant impact on Foreign Direct Investment inflow. Specifically, tax holiday has significant positive effect on FDI at 5% level of significance (β=0.1578; t=3.99; p<0.05) while custom duties exemption reported significant positive effect on FDI at 1% level of significance (β=0.2436; t=5.61; p<0.01). It is recommended that the government maintain and strengthen its policies on tax holidays and customs duties exemption to improve Foreign Direct Investment inflow, thereby developing the national economy.
Asthma with Fixed Airflow Obstruction: From Fixed to Personalized Approach

Asthma is generally characterized by variable symptoms such as dyspnea and wheezing and variable airflow obstruction. This review focuses on a subset of patients suffering from asthma with persistent airflow limitation that is not fully reversible (asthma with fixed airflow obstruction, FAO). The pathophysiology, the risk factors and the clinical outcomes associated with FAO are presented, as well as the distinct clinical entity of severe asthma and its inflammatory subtypes (T2 and non-T2). The current strategies for the treatment of these endotypes and treatment of the distinct Asthma/COPD overlap (ACO) phenotype are described. Management and medical interventions in FAO and/or ACO patients demand a holistic approach, which is not yet clearly established in guidelines worldwide. Finally, a treatment algorithm that includes FAO/ACO management based on pharmacological and non-pharmacological treatment, guideline-based management for specific co-morbidities, and modification of the risk factors is proposed.
Predatory journals and publishers: Characteristics and impact of academic spam to researchers in educational sciences

This study focuses on the phenomenon of presumed predatory scientific publications in the field of Educational Sciences, and the utilization of email by editors to request manuscripts. It examined, using content analysis methods, 210 emails received by three professors of the field of Education, at a Spanish university with different research profiles over a period of 3 months. Through analysis of the unsolicited emails a total of 139 journals and 37 publishers were identified and examined using: (a) the two main predatory journal inventories (Beall's list and Cabells' Predatory Reports), and (b) six of the major scientific bibliographic databases. The publishers and their websites were also analyzed, as well as the basic aspects of the emails' content. The majority of the unsolicited emails were from predatory journals or publishers and half of the article requests did not match the field of the recipient. In addition, it is relevant to note that more than half of the domains of predatory publishers analysed have untrustworthy security levels. The data provided relevant information on the phenomenon of predation in scientific publications in the field of Education and, most importantly, provided evidence for developing training and preventive strategies to tackle it.
THE ROLE OF RESILIENCE AND READINESS FOR CHANGE ON STUDENTS’ INTEREST IN LEARNING: E-LEARNING IMPLEMENTATION DURING COVID-19

COVID-19 affects the learning system at university. This study aims to determine the relationship between resilience and readiness for changes on students’ interest to learn in Faculty of Psychology, Universitas Diponegoro, Indonesia, under the implementation of e-learning system during the COVID-19 pandemic. The subjects in this study were 190 Students (M = 37, F = 153). The sampling technique used was cluster random sampling. The instruments used were the CD-RISC (16 items; α = .886), readiness for change questionnare (28 items; α = .919), and interest in leaning questionnare (14 items; α = .882). The multiple regression analysis show that there was a positive and significant correlation between resilience and interest in learning (r = .555; p < .001), and a positive and significant correlation between readiness for change and interest in learning (r = .580; p < .001). Furthermore, resilience and readiness for change together can predict students’ interest in learning during e-learning implementation (r = .675, p < .001), R = . 456, F = 78,294; p < . 001). Resilience and readiness for change effectively contributed 45.6% to predicting students’ interest in learning. These results suggest that students have resilience and readiness for change so that their interest in learning remains high despite having to face uncertain situation.
A situational analysis of clinical refraction services in the capital city of the Maldives

Background: Uncorrected refractive error is a leading cause of visual impairment globally. This study aimed to determine the current state of clinical refraction services and barriers to service provision in the capital city of the Maldives. Methods: This cross-sectional, descriptive-analytical study used a purposive sampling technique. The list of facilities providing refraction services in the city of Malé was compiled through a desk review and finalized after verification by personnel from the Ministry of Health. The availability of human resources and infrastructure was measured using a pre-coded questionnaire that also listed barriers to service provision, followed by on-site observations and subsequent data analysis. Results: Three clinical ophthalmology departments within hospitals, two ophthalmology hospitals, and nine primary eye care centers were selected for this study. The private sector (n = 12, 85.7%) was the primary provider of refractive error services. All facilities possessed the essential equipment required for refraction. Only optometrists and ophthalmologists conducted refraction. Contact lens assessment and low vision services were not available at any facility. The number of refractions conducted in Malé annually was 145,392. Human resources and management-related factors were the major barriers to the provision of clinical refraction services (n = 21, 44.7%). Conclusions: Accessibility to refractive error management and low vision services is needed in Malé to meet current population needs. Existing resources, including humans and equipment, require augmentation regarding service provision and enhancement. Knowledge of these barriers could lead to the upscaling of refraction services in Malé, Maldives by health policy makers.
Board meetings and bank performance in Africa

Abstract This study examines the relationship between a board meeting and banks performance in Africa. This paper provides insight on this question after taking into account the endogeneity of the relationship between board meetings and performance. Specifically, we use the GMM technique and a sample of 635 banks from 48 countries in Africa between 2000 to 2016 to test our hypothesis and found that more board meetings, averagely 6, reduce banks’ performance in sub-Sahara Africa. In the Northern Africa context, with an average board meeting of 7.68, however, we document a positive and significant association between a board meeting and bank performance. Our result suggests that fewer board meeting enhances the shareholder value of Banks in Sub-Sahara Africa but not their counterparts in North Africa. Our paper provides insights to policymakers responsible for improving the governance mechanisms in African banks.
Solving the Max-3-Cut Problem with Coherent Networks

Many computational problems are intractable through classical computing and, as Moore’s law is drawing to a halt, demand for finding alternative methods in tackling these problems is growing. Here, we realize a liquid light machine for the NP-hard max-3-cut problem based on a network of synchronized exciton-polariton condensates. We overcome the binary limitation of the decision variables in Ising machines using the continuous-phase degrees of freedom of a coherent network of polariton condensates. The condensate network dynamical transients provide optically-fast annealing of the XY Hamiltonian. We apply the Goemans and Williamson random hyperplane technique, discretizing the XY ground state spin configuration to serve as ternary decision variables for an approximate optimal solution to the max-3-cut problem. Applications of the presented coherent network are investigated in image-segmentation tasks and in circuit design.
Identification of Risk Factors for Coronary Artery Disease in Asymptomatic Patients with Type 2 Diabetes Mellitus

Background: Patients with diabetes mellitus (DM) are a high-risk group for coronary artery disease (CAD). In the present study, we investigated predictive factors to identify patients at high risk of CAD among asymptomatic patients with type 2 DM based on coronary computed tomographic angiography (CCTA) findings. Methods: A single-center prospective study was performed on 452 consecutive patients with type 2 DM who were provided with a weekly hospital-based diabetes education program between 3 October 2015, and 31 March 2020. A total of 161 consecutive asymptomatic patients (male/female: 111/50, age: 57.3 ± 9.3 years) with type 2 DM without any known CAD underwent CCTA. Based on conventional coronary risk factors and non-invasive examination, i.e., measurement of intima-media thickness, subcutaneous and visceral fat area, a stress electrocardiogram test, and the Agatston score, patients with obstructive CAD, CT-verified high-risk plaques (CT-HRP), and optimal revascularization within 90 days were evaluated. Results: Current smoking (OR, 4.069; 95% C.I., 1.578–10.493, p = 0.0037) and the Agatston score ≥100 (OR, 18.034; 95% C.I., 6.337–51.324, p = 0.0001) were independent predictive factors for obstructive CAD, while current smoking (OR, 5.013; 95% C.I., 1.683–14.931, p = 0.0038) was an independent predictive factor for CT-HRP. Furthermore, insulin treatment (OR, 5.677; 95% C.I., 1.223–26.349, p = 0.0266) was the only predictive factor that correlated with optimal revascularization within 90 days. Conclusions: In asymptomatic patients with type 2 DM, current smoking, an Agatston score ≥100, and insulin treatment were independent predictive factors of patients being at high-risk for CAD. However, non-invasive examinations except for Agatston score were not independent predictors of patients being at high risk of CAD.
Nursing practices associated with diagnosis of malnutrition in children under 5 years in West Rand District primary healthcare facilities

Background: Despite improvement in child health outcomes, undernutrition in children aged under five years continues to be a major public health problem, contributing to childhood morbidity and mortality. Objectives: The aim was to determine the knowledge and practice patterns used in the identification of malnutrition by nurses at PHC facilities. The attendance rates and the impact of in-house paediatric courses were also examined. Design: An observational, descriptive, cross-sectional study was undertaken from June to September 2018. Setting: The study was conducted at 36 primary healthcare clinics in the West Rand Health District Council Area, Gauteng, South Africa. Subjects: All nurses working with children aged under five years in the study clinics. Results: The response rate was 94% (49) with a mean age of 42.5 years (±9.7) with the majority (98%) being females. Nearly two-thirds (61%) of the participants had good knowledge, 33% had excellent knowledge and 6% had poor knowledge. The mean knowledge score was 20.3 (8–27, SD). The practice categories indicated that two-thirds of the participants (61%) displayed poor practices, and 21% had good practices whilst only 18% displayed best practices. The mean practice score was 4.5 (1.75, SD). There was no association between attendance at courses, knowledge scores and practice patterns. Conclusion: Most participants had good or excellent knowledge around issues of malnutrition. There was poor attendance on courses and there was no association between knowledge and attendance on the courses. More than 60% of the nurses had poor practice patterns and there was no association between knowledge, attendance on courses and practice patterns.
The Impact of SARS-CoV-2 Primary Vaccination in a Cohort of Patients Hospitalized for Acute COVID-19 during Delta Variant Predominance

Vaccine breakthrough SARS-CoV-2 infections necessitating hospitalization have emerged as a relevant problem with longer time interval since vaccination and the predominance of the Delta variant. The aim of this study was to evaluate the association between primary vaccination with four SARS-CoV-2 vaccines authorized for use in the European Union—BNT162b2, ChAdOx-1S, mRNA-1273 or Ad.26. COV2.S—and progression to critically severe disease (mechanical ventilation or death) and duration of hospitalization among adult patients with PCR-confirmed acute COVID-19 hospitalized during the Delta variant predominance (October–November 2021) in Slovenia. Among the 529 enrolled patients hospitalized with COVID-19 (median age, 65 years; 58.2% men), 175 (33.1%) were fully vaccinated at the time of symptom onset. Compared with 345 unvaccinated patients, fully vaccinated patients with breakthrough infections were older, more often immunocompromised, and had higher Charlson comorbidity index scores. After adjusting for sex, age, and comorbidities, fully vaccinated patients had lower odds for progressing to critically severe disease and were discharged from the hospital earlier than unvaccinated patients. Vaccination against SARS-CoV-2 remains an extremely effective intervention to alleviate morbidity and mortality in COVID-19 patients.
Effects of KinesioÂ® Tape vs Rigid Tape on Shoulder Muscle Strength in Healthy Tennis Players

Background: Many athletic trainers and therapists use taping to improve the performance of their athletes however, there is limited research on how and which taping techniques influence the athletesâ€™ performance. Objective: The purpose of this study was to determine the effects of applying KinesioÂ® tape (KT) and rigid tape on shoulder isokinetic muscle strength of healthy tennis players. Methods: Forty five male tennis players (age: 24 Â± 6, weight: 75.38 Â± 11.43kg, height: 177.05 Â± 7.19cm) were recruited. Shoulder isokinetic muscle strength was measured with an isokinetic dynamometer before and 30 minutes after taping in three groups: with KT, with rigid tape and no tape. Results: The results revealed that the mean peak torque in KT group was significantly higher than rigid tape and control group except external rotation at 60â—¦/s. Power with KT was significantly higher than rigid tape and control tape for all conditions but there was no significant difference between the rigid and control group (P<0.05). Conclusions: The results imply that for increasing the isokinetic muscle strength in athletes and as a result enhancing the athletic performance, facilitatory Kinesio taping is a more effective option rather than rigid taping. KEY WORDS: Isokinetic Dynamometer, Peak torque, Average Power, Muscle function

More than a Bubble: Extracellular Vesicle microRNAs in Head and Neck Squamous Cell Carcinoma

Simple Summary Head and neck squamous cell carcinoma (HNSCC) is an aggressive and lethal disease. Despite diagnostic and therapeutic advances, the overall survival of patients with advanced HNSCC remains poor. Recently, microRNAs in extracellular vesicles (EV-miRNAs) have been proposed as essential regulatory molecules involved in HNSCC. EV-miRNAs may serve as disease biomarkers and represent a novel therapeutic target. This review summarizes the current understanding of the role of EV-miRNAs in HNSCC as well as their potential future clinical applications. Abstract MicroRNAs (miRNAs) are a class of small non-coding RNA molecules that play a pivotal regulatory role in a broad variety of biological processes. Dysregulation of miRNAs is associated with several human diseases, particularly cancer. Extracellular vesicles (EVs) are crucial components in intercellular communication. As part of the cargo of EVs, miRNAs are involved in EV-mediated cell-to-cell interactions, including promotion or suppression of tumor development. The knowledge on the molecular mechanisms and clinical importance of EV-miRNAs in head and neck squamous cell carcinoma (HNSCC) has rapidly grown over the past years. In the present review, the current understanding regarding the effect of EV-miRNAs on HNSCC tumorigenesis is summarized, which includes effects on tumor proliferation, angiogenesis, invasion and metastasis, the tumor microenvironment, immune modulation, and treatment resistance. EV-miRNA-based biomarkers in liquid biopsies such as blood and saliva may open up new possibilities for employing EV-miRNAs for screening and early diagnostics as well as disease monitoring. Future perspectives include the promise of EV-miRNAs as a novel therapeutic target.
