COVID-19-Related Pulmonary Embolism: Incidence, Characteristics, and Risk Factors

Introduction: The 2020 world pandemic caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was initially reported in December 2019 in Wuhan, China, which has since then spread globally. Several studies on patients with coronavirus disease 2019 (COVID-19) describe a high risk of pulmonary embolism (PE). The majority of PEs in patients with COVID-19 were in the segmental arteries. Therefore, this study aims to determine the rate of PE in patients with COVID-19 at King Abdulaziz Medical City in Jeddah, Saudi Arabia. Other risk factors of PE were taken into consideration. Patients and Methods: This study is a single-center, retrospective, cross-sectional study that used a non-probability consecutive sampling technique to select the patients. The local institutional review boards approved the study protocol. Overall, 91 consecutive patients who were older than 18 years of age and who had a computerized tomography (CT) pulmonary angiography were included in this study. Results: Ninety-one patients met the inclusion and exclusion criteria, of whom 46 (50.5%) were females and 45 (49.5%) were males. The study population’s age ranged from 19 to 87 with a mean age of 59 ± 15 years. PE was documented in 11 patients (12.1%). Seventy-three patients underwent CT scan angiography during COVID-19 manifestation, while 18 patients had it after recovering from COVID-19. Out of the 11 patients with PE, eight were diagnosed with PE while being COVID-19 positive, and three were diagnosed with PE after recovery from COVID-19. Conclusion: Several potential clinical implications can be concluded for this study. Firstly, effective evaluation of the risk of PE in patients with COVID-19 is based on clinical findings such as chest pain, hemoptysis, lower limb edema, and, most significantly, shortness of breath. Secondly, measuring D-dimer remains an effective test for ruling out PE in patients with COVID-19 as in patients without COVID-19.
Preliminary design and fast prototyping of an Autonomous Underwater Vehicle propulsion system

The Mechatronics and Dynamic Modelling Laboratory of the Department of Industrial Engineering, University of Florence, as a partner of THESAURUS (Italian acronym for ‘TecnicHe per l’Esplorazione Sottomarina Archeologica mediante l’Utilizzo di Robot aUtonomi in Sciami’) project, has developed an innovative low-cost, multirole autonomous underwater vehicle, called Tifone. This article deals with the adopted methodologies for the autonomous underwater vehicle design: in particular, the main focus of this study is related to its propulsion system. According to the expected performances and requirements of THESAURUS project, the vehicle has to maintain good autonomy and efficiency (typical features of an autonomous underwater vehicle), with high manoeuvrability and hovering capabilities, which are more common of remotely operated vehicles. Moreover, cooperative underwater exploration and surveillance involve the use of a swarm of vehicles. In particular, the optimization of costs versus benefits is achieved through the design of a fleet of three multirole vehicles. Each autonomous underwater vehicle has five controlled degrees of freedom, thanks to four thrusters and two propellers: in this article, the preliminary design criteria concerning the vehicle and the design and testing of its actuation system are described.
Computational Investigations of a pH-Induced Structural Transition in a CTAB Solution with Toluic Acid

In this work, molecular dynamics simulations were performed to study the pH-induced structural transitions for a CTAB/p-toluic acid solution. Spherical and cylindrical micelles were obtained for aqueous surfactants at pH 2 and 7, respectively, which agrees well with the experimental observations. The structural properties of two different micelles were analyzed through the density distributions of components and the molecular orientations of CTA+ and toluic acid inside the micelles. It was found that the bonding interactions between CTA+ and toluic in spherical and cylindrical micelles are very different. Almost all the ionized toluic acid (PTA−) in the solution at pH 7 was solubilized into the micelles, and it was located in the CTA+ headgroups region. Additionally, the bonding between surfactant CTA+ and PTA− was very tight due to the electrostatic interactions. The PTA− that penetrated into the micelles effectively screened the electrostatic repulsion among the cationic headgroups, which is considered to be crucial for maintaining the cylindrical micellar shape. As the pH decreased, the carboxyl groups were protonated. The hydration ability of neutral carboxyl groups weakened, resulting in deeper penetration into the micelles. Meanwhile, their bonding interactions with surfactant headgroups also weakened. Accompanied by the strengthen of electrostatic repulsion among the positive headgroups, the cylindrical micelle was broken into spherical micelles. Our work provided an atomic-level insights into the mechanism of pH-induced structural transitions of a CTAB/p-toluic solution, which is expected to be useful for further understanding the aggregate behavior of mixed cationic surfactants and aromatic acids.
Impact of Evaluation of Different Irrigation Methods with Sensor System on Water Consumptive Use and Water Use Efficiency for Maize Yield

The sensor system is one of the modern and important methods of irrigation management in arid and semi-arid areas, which is water as the limiting factor for crop production. The study was applied for 2016 and 2017 seasons out in Al-Yousifya, 15 km Southwest of Baghdad. A study was conducted to evaluate coefficient uniformity, uniformity distribution and application efficiency for furrow, surface drip and subsurface drip irrigation methods and it was (98, 97 and 89)% and (97, 96 and 88)% for 2016 and 2017 seasons; respectively. And control the volumetric moisture content according to the rhizosphere depth for depths of 10, 20 and 30 cm by means of the sensor system. The results indicated that the height consumptive water use of furrow 707.91 and 689.69 mm∙season and the lowest for subsurface drip with emitter deep at 20 cm 313.93 and 293.50 mm∙season for 2016 and 2017 seasons; respectively. As well, the highest value of water use efficiency for subsurface in drip irrigation at a depth of 20 cm, was 2.71 and 2.99 kg∙m and the lowest value for furrow irrigation was 1.12 and 1.20 kg∙m for the 2016 and 2017 seasons; respectively.
Prevalence of alopecia and its contributing factors among primary healthcare attendees in the Jazan region, Saudi Arabia

Background: Alopecia is a common health condition that can be associated with social and psychological consequences. Aims: This study aims to estimate the prevalence of hair loss and its associated risk factors among primary healthcare center (PHC) attendees in the Jazan region. Methods: This investigation was a cross-sectional study conducted in the Jazan region of southwest Saudi Arabia. A total of 23 PHCs were randomly selected from five governorates in the region. Data were collected via interviewing PHCs attendees and were asked about their demographic characteristics, presence of hair loss, and among attendees who confirmed having hair loss, they were further asked about associated clinical features, healthcare-seeking behavior, and factors that might contribute to the development of their condition. Results: A total of 729 participants consented to be involved in this study. The number of respondents who reported having hair loss was 483, representing 66.3% of the whole sample. Gender appears to have the highest level of variability, with the majority of participants reporting hair loss being female (P < 0.001). The most frequently reported type of hair loss was telogen effluvium, followed by androgenic alopecia. A total of 185 respondents reported taking medications to treat their hair loss, of whom 108 (58.3%) did not seek any medical advice to identify the cause of their condition. Limitations: The main weakness of this investigation is related to relying on a reported presence of hair loss without having it confirmed with a clinical diagnosis. Conclusion: A minority of participants who reported suffering from hair loss were further evaluated by healthcare professionals to learn the cause of their hair loss. This may indicate the presence of poor hair care and the probability of a higher risk of hair loss requiring the development of suitable preventive strategies.
Introduction to weather derivatives

The weather is one of the factors that may have an impact on the countries' economies. There are two main hedging ways against unexpected weather conditions: weather derivatives and weather insurances. During the last two decades, companies started to use weather derivatives against weather issues, especially in the energy and agriculture sectors. Starting from weather derivatives' first launch, their transaction volumes at the exchange and over‐the‐counter markets have increased. In addition to the increasing dependency of the economies on the weather, providing the weather derivative contracts with a reasonable premium amount is another reason which helps to have this positive trend. Since weather derivatives have similar parameters and rules with classical financial derivatives, it is possible to use the same pricing approaches for financial and weather derivatives. Monte–Carlo simulation, based on random number generation, is one of the existing methods of pricing derivative contracts. A difference between simulated values and really occurred data is the base point of the expected payoff or price of the contract. The current article introduces weather derivatives and shows two different approaches to their pricing, where one of them requires deeper statistical analysis. Adding the statistical analysis into the consideration, defining the relation between each data value, helps to provide better estimation and less volatility. Having less volatility can provide more accurate estimations and reasonable prices that are affordable and desired by the companies.
Serum Biomarkers in Carotid Artery Disease

Carotid artery disease is considered a major cause of strokes and there is a need for early disease detection and management. Although imaging techniques have been developed for the diagnosis of carotid artery disease and different imaging-based markers have been proposed for the characterization of atherosclerotic plaques, there is still need for a definition of high-risk plaques in asymptomatic patients who may benefit from surgical intervention. Measurement of circulating biomarkers is a promising method to assist in patient-specific disease management, but the lack of robust clinical evidence limits their use as a standard of care. The purpose of this review paper is to present circulating biomarkers related to carotid artery diagnosis and prognosis, which are mainly provided by statistical-based clinical studies. The result of our investigation showed that typical well-established inflammatory biomarkers and biomarkers related to patient lipid profiles are associated with carotid artery disease. In addition to this, more specialized types of biomarkers, such as endothelial and cell adhesion, matrix degrading, and metabolic biomarkers seem to be associated with different carotid artery disease outputs, assisting vascular specialists in selecting patients at high risk for stroke and in need of intervention.
External workload intensity in cricket fast bowlers across maximal and submaximal intensities: Modifying PlayerLoad and IMU location

ABSTRACT Workload is a commonly accepted risk factor for injury among fast bowlers, however many methods exist to characterise workload. Recently, automated intensity-sensitive measures like PlayerLoad have been used to improve the estimation of workload in fast bowlers. The purpose of this study was to determine whether similar variables could be extracted from a single inertial measurement unit (IMU) that highly correlate with intensity, according to release speed. Eight elite and pre-elite bowlers participated in the study, with each bowler bowling one over each at 60%, 80% and 100% intensity and repeating this across two sessions (36 balls per participant). IMUs were placed on the upper-back and non-bowling wrist and maximum PlayerLoad from each delivery (PLmax) was compared to the accumulated value across each delivery (PLacc). The strongest correlation with release speed was with PLacc from the non-bowling wrist (R = 0.74), followed by PLacc from the upper-back (R = 0.65) and PLmax from the upper back (R = 0.60). Consequently, an improved estimation of the intensity at which bowlers are working at could be gained by examining accumulated PlayerLoad values from an IMU on the non-bowling wrist.
Sources of Power: How People Make Decisions

Anyone who watches the television news has seen images of firefighters rescuing people from burning buildings and paramedics treating bombing victims. How do these individuals make the split-second decisions that save lives? Most studies of decision making, based on artificial tasks assigned in laboratory settings, view people as biased and unskilled. Gary Klein is one of the developers of the naturalistic decision-making approach, which views people as inherently skilled and experienced. Since 1985, Klein has conducted fieldwork to find out how people tackle challenges in difficult, nonroutine situations. Sources of Power is based on observations of humans acting under such real-life constraints as time pressure, high stakes, personal responsibility, and shifting conditions. In addition to providing information that can be used by professionals in management, psychology, engineering, and other fields, the book presents an overview of the research approach of naturalistic decision making and expands our knowledge of the strengths people bring to difficult tasks.

Analysis of Factors Affecting Post-Stroke Fatigue: An Observational, Cross-Sectional, Retrospective Chart Review Study

Post-stroke fatigue (PSF) is one of the most common emotional and mood disorders in stroke survivors. Several studies have suggested associations between PSF and various factors. However, they describe conflicting results. Therefore, this study aimed to evaluate the factors affecting PSF. We retrospectively reviewed the medical records of 178 hospitalized stroke patients. The collected data were compared between the PSF and control groups. To evaluate the association between factors and PSF, regression analysis was conducted. A total of 96 patients (53.9%) were assigned to the PSF group, and 82 patients were assigned to the control group. Age, neurological deficits, cognitive dysfunction, degree of depression, hs-CRP, and ESR differed significantly between the two groups. For both types of stroke, multiple linear regression analyses showed that degree of depression and degree of inflammation were significantly associated with PSF. Through subgroup analysis, multiple linear regression analyses showed that the degree of depression in ischemic and hemorrhagic stroke and the platelet-to-lymphocyte ratio in hemorrhagic stroke had a significant association with PSF. In conclusion, post-stroke depression and degree of inflammation could be clinically significant predictors of PSF in all types of stroke patients. However, larger, prospective studies are required to obtain more concrete results.
Sustainable construction: principles and a framework for attainment

The evolution of the concept of sustainable development is used as a basis for advancing understanding of sustainable construction. Principles of sustainable construction are developed and divided into four 'pillars' - social, economic, biophysical and technical - with a set of over-arching, process-oriented principles, to be used as a checklist in practice. A multi-stage framework is proposed which requires the application of Environmental Assessment and Environmental Management Systems for construction projects.
Developing an Interactive University Orientation App: Potential Users' Feedback

Abstract— The use of apps has become increasingly common in higher institutions and often linked with the needs of the current generation. This qualitative study investigates the perception of undergraduate students at a university in Malaysia as part of a need analysis to develop a university orientation app. Fifteen participants were interviewed and the findings suggest that the participants have a positive perception of having the app. The positive perception is mainly based on the needs to navigate around the campus where the apps will help to make the navigation easier and effective by serving as ‘one-stop information center’. In addition to the navigation purpose, the potential users request gamification elements to keep them interested in using the app. This paper concludes that an appealing orientation app for the students should expose them to the university surrounding and at the same time contain gamification elements.
Implementing a “convergent” framework of action against childhood malnutrition in urban informal settlements of Mumbai: Frontline perspectives

Context: The National Nutrition Mission (POSHAN Abhiyaan) intends to “converge” nutrition-related program components across sectors (nutrition, health, water, and sanitation). In this study, we have examined the perspectives of Anganwadi workers (AWWs), the frontline workers of the Integrated Child Development Services, on working in convergence with the public health sector. Methods: This exploratory qualitative study was done between June 2018 and June 2019 in two urban informal settlements in Mumbai. We conducted in-depth interviews with 26 AWWs and their supervisors, purposively sampled and diversified in terms of age, education, and years of experience. We used the software NVivo version 12 to aid analysis. Results: Most AWWs acknowledged that a convergent framework of action between “nutrition” and “health” was likely to be beneficial to the community. However, they also shared that cross-sector convergence was currently limited due to technical unfamiliarity with “health-sector” issues in the frontline, discomfort with data sharing, and lack of meaningful incentives for joint work. Broader organizational challenges such as poor infrastructure and lack of supervision, as well as challenges in the urban context (migration and cultural barriers) further hindered joint activities. Conclusions: The findings indicate that critical structural gaps in the urban setup of ICDS need to be addressed and AWWs need to be better familiarized with the changing roles expected from them under POSHAN Abhiyaan. To work better with the health sector, the work timings of AWWs need to be aligned with those of the health sector and meaningful financial incentives need to be put in place for cross-sector activities.
EMPLOYABILITY SKILLS OF TECHNICAL AND VOCATIONAL STUDENTS WITH HEARING IMPAIREMENTS: EMPLOYERS’ PERSPECTIVES

This study aims to explore the employers’ requirement for employability skills of the technical and vocational students who are hearing impaired. The research instrument used was adapted from the Secretary's Commission on Achieving Necessary Skills (SCANS) which consists of thirty nine items. The employability skills surveyed include basic skills, thinking skills, personal qualities, sourcing skills, information skills, interpersonal skills, system skills and technology skills. The instrument was distributed to 110 industry employers throughout Malaysia. However, only 23 (21%) employers returned the survey form. The majority of respondents are from service industry (78.2%) including the retail, food service, restaurants and hotel as well as the fashion designing industry. A high percentage of the respondents (65.2%) are Human Resource Manager who had one to five years of working experience. Based on the survey, the three top most highly rated skills are, personal qualities (M=4.37, SD=.39), basic skills (M=4.10, SD=.58) and interpersonal skills (M=4.07, SD=.47). Knowing the skills that employers demand from their hearing impaired employees, institutions can provide the appropriate training to prepare their hearing impaired graduates for future employment.
Preservice Chemistry Teachers’ Epistemic Beliefs After a Student-Centred Approach Training Programme

Recent studies in science education have recognized a possible link between teachers’ beliefs about scientific knowledge and its practice in the classroom. Therefore, it is essential to promote the evolution of the pre-service teachers’ initial beliefs about methodologies for the teaching of chemistry in accordance with the discipline foundations and current recommendations on science teaching. We present the implementation and evaluation of a sequence of activities with a student-centred teaching approach for the training of pre-service science secondary education teachers. Inquiry, modelling, argumentation, as well as game-based learning are examples of the methodologies used. The results show a change of orientation from the epistemic beliefs prior to the programme implementation and highlight significant differences with respect to the relevance given by the teachers to carrying out research activities. For future teachers to develop professional competence, it is necessary to offer them opportunities to experience alternative methodologies during their training.
