A qualitative Design and optimization of CIGS-based Solar Cells with SnS Back Surface Field: A plan for achieving 21.83 % efficiency.

Conventional Copper Indium Gallium Di Selenide (CIGS)-based solar cells are more efficient than second-generation technology based on hydrogenated amorphous silicon (a-Si: H) or cadmium telluride (CdTe). So, herein the photovoltaic (PV) performance of CIGS-based solar cells has been investigated numerically using SCAPS-1D solar simulator with different buffer layer and less expensive tin sulfide (SnS) back-surface field (BSF). At first, three buffer layer such as cadmium sulfide (CdS), zinc selenide (ZnSe) and indium-doped zinc sulfide ZnS:In have been simulated with CIGS absorber without BSF due to optimized and non-toxic buffer.

COVID-19 and Anemia: What Do We Know So Far?

On 11 March 2020, the World Health Organization (WHO) declared the novel SARS-CoV-2 virus responsible for causing COVID-19, a global pandemic. The virus primarily targets the respiratory system but can also affect other systems, notably causing hematological pathologies. Anemia, a common hematologic disorder, is characterized by the reduced oxygen-carrying capacity of red blood cells.

Prevalence of Dry Eye Disease Among Medical Students and Its Association with Sleep Habits, Use of Electronic Devices and Caffeine Consumption: A Cross-Sectional Questionnaire.

The prevalence rate among medical students is an important issue to consider. This study investigates the relationship between caffeine consumption, sleeping habits, use of electronic devices, and DED among a convenient sample of medical students in Jordan.

Effects of ABO blood groups and RH-factor on COVID-19 transmission, course and outcome: A review.

ABO and Rh blood grouping systems are two of the non-modifiable risk factors that play an important role in the susceptibility, severity and outcomes of COVID-19 infection. This review explores these associations all over the world, in an attempt to conclude a clear idea for future reference in clinical practice. In the present review, a link has been drawn between blood groups and COVID-19 transmission, course and prognosis, as literature suggests that blood group O plays a protective role against the infection, while blood group A exhibits a higher risk of exacerbation.

Face masks, along with other preventive measures, can help slow the spread of COVID-19. Despite the positive effect of the mask in combating the virus, it has some negative effects on the human body that must be followed up on and reduced. In this study, we discuss the impact of wearing face masks on the eye and the common issues associated with using them.

Ocular manifestations of recent viral pandemics: A literature review.

Viral pandemics often take the world by storm, urging the medical community to prioritize the most evident systemic manifestations, often causing ocular manifestations to go unnoticed. This literature review highlights the ocular complications of the Monkeypox, SARS-CoV-2, MERS, Ebola, H1N1, and Zika viruses as the most recent viral pandemics. Research into the effects of these pandemics began immediately.

Is wearing a face mask associated with symptomatic dry eye disease among medical students during the COVID-19 era? An online survey.

Background: Coronavirus disease 2019 has necessitate the routine use of masks worldwide. This study assessed the relationship between wearing a facemask and dry eye disease (DED) among a sample of medical students in Jordan.

Methods: This cross-sectional online survey enrolled medical students from all medical schools in Jordan.

Artificial Intelligence in Medicine: A Multinational Multi-Center Survey on the Medical and Dental Students' Perception.

The emerging field of artificial intelligence (AI) will probably affect the practice for the next generation of doctors. However, the students' views on AI have not been largely investigated. An anonymous electronic survey on AI was designed for medical and dental students to explore: (1) sources of information about AI, (2) AI applications and concerns, (3) AI status as a topic in medicine, and (4) students' feelings and attitudes.

Conjunctivitis as the only sign and symptom of COVID-19: A case report and review of literature.

Similar to several viruses, coronaviruses can affect the eye and cause conjunctivitis. In addition to ocular involvement, it causes systemic manifestations, mainly respiratory symptoms. However, conjunctivitis as the only sign and symptom of coronavirus disease 2019 (COVID-19) is a rare presentation.

Impact of social media on public fear, adoption of precautionary behaviors, and compliance with health regulations during COVID-19 pandemic.

Social media has become an essential source of information during the coronavirus disease 2019 (COVID-19) pandemic. This study aims to understand social media's effect on the general public's fear, degree of adopting precautionary behaviors, and compliance with health authorities' regulations during the pandemic. A cross-sectional online survey was conducted in Jordan during the early period of COVID-19 pandemic.

Role of a Solution-Processed VO Hole Extracting Layer on the Performance of CuO-ZnO-Based Solar Cells.

In this research, a heterostructure of the CuO-ZnO-based solar cells has been fabricated using low-cost, earth-abundant, non-toxic metal oxides by a low-cost, low-temperature spin coating technique. The device based on CuO-ZnO without a hole transport layer (HTL) suffers from poor power conversion efficiency due to carrier recombination on the surface of CuO and bad ohmic contact between the metal electrode and the CuO absorber layer. The main focus of this research is to minimize the mentioned shortcomings by a novel idea of introducing a solution-processed vanadium pentoxide (VO) HTL in the heterostructure of the CuO-ZnO-based solar cells.

Occupational burnout and job satisfaction among physicians in times of COVID-19 crisis: a convergent parallel mixed-method study.

Background: Healthcare professionals including physicians were subjected to an increased workload during the COVID-19 crisis, leaving them exposed to significant physical and psychological distress. Therefore, our present study aimed to (i) assess the prevalence of burnout and levels of job satisfaction among physicians in Jordan, and (ii) explore physicians' opinions, experiences, and perceptions during the pandemic crisis.

Methods: This was a mixed-method study that utilized a structured web-based questionnaire and semi-structured individual interviews.

Solution-Processed Synthesis of Copper Oxide (Cu O) Thin Films for Efficient Photocatalytic Solar Water Splitting.

This article reports a solution-processed synthesis of copper oxide (Cu O) to be used as a potential photocathode for solar hydrogen production in the solar water-splitting system. Cu O thin films were synthesized through the reduction of copper iodide (CuI) thin films by sodium hydroxide (NaOH), which were deposited by the spin coating method from CuI solution in a polar aprotic solvent (acetonitrile). The phase and crystalline quality of the synthesized Cu O thin films prepared at various annealing temperatures were investigated using various techniques.

Effectiveness and safety of nasal mask versus binasal prongs for providing continuous positive airway pressure in preterm infants-A systematic review and meta-analysis.

Continuous positive airway pressure (CPAP) delivered via binasal prongs has been the cornerstone of respiratory management in preterm infants. Though effective, the use of binasal prongs is associated with nasal trauma, and CPAP failure. To overcome these issues, nasal masks are increasingly used to deliver CPAP in preterm infants.

A founder splice site mutation underlies glycogen storage disease type 3 in consanguineous Saudi families.

Background And Objectives: Glycogen storage disease type 3 (GSD III) is an autosomal recessive disorder caused by genetic mutations in the gene AGL. AGL encodes amylo-a-1, 6-glucosidase, 4-a-glucanotransferase, a glycogen debranching enzyme. GSD III is characterized by fasting hypoglycemia, hepatomegaly, growth retardation, progressive myopathy, and cardiomyopathy due to storage of abnormally structured glycogen in both skeletal and cardiac muscles and/or liver.

Investigation on light-addressable potentiometric sensor as a possible cell-semiconductor hybrid.

This article reports an investigation on light-addressable potentiometric sensor (LAPS) to be used as a possible biological cell-semiconductor hybrid that will enable us to make an interface between the physical and biological system. To increase the surface potential sensitivity, we used a LAPS structure with single insulator (SiO2) coated with poly-L-ornithine and laminin (PLOL) on Si. Efficient culturing of PC-12 and nerve cells of Lymnaea stagnalis on PLOL-coated Si3N4 and SiO2 was achieved.
