Perspectives of nursing among male pre-nursing students: a Q-methodology study

Nursing continues to face workforce shortages globally, and increasing the participation of men has been identified as one strategy for strengthening workforce capacity. In Saudi Arabia, efforts to expand and sustain the national nursing workforce have highlighted the importance...

Exploring the Link: A Study on Consanguinity and Orofacial Clefts

Objective To evaluate the association between parental consanguinity and cleft phenotype, family history, syndromic status, regional distribution, and sex-specific presentation among Saudi patients affected by cleft lip and/or palate (CL/P). Design Retrospective cross-sectional o...

Fundamental Insights Toward Efficient Hydrogen Storage: Materials Design Considerations in Nanostructured and Polymer–Hybrid Systems

Hydrogen is a promising alternative energy source as the world moves toward decarbonization by reducing reliance on traditional fossil fuels. This review encompasses a comprehensive study of emerging materials for hydrogen storage, beginning with the physical and thermodynamic pr...

3D assessment of the marginal and internal gap and fracture load of ceramic surveyed inlays designed for removable partial denture support: An in vitro comparative study

PURPOSE: To assess the internal and marginal gaps and the fracture load of different machinable ceramics for an inlay acting as a support for a removable partial denture. MATERIALS AND METHODS: Sixty extracted human teeth (first maxillary premolar) were collected (n = 10 for each...

Direct Graft Copolymerization of Cellulose Acetate Membrane with Bio-Based Itaconic Acid for Pollutant Removal from Wastewater

Cellulose acetate (CA) is a promising bio-derived membrane material for water treatment; however, its limited availability of active functional sites can restrict its affinity toward dissolved pollutants. In this study, a cellulose acetate membrane was fabricated by phase inversi...

Diagnostic Yield of Comprehensive Etiologic Evaluation in Young Adults with Ischemic Stroke: Toward a Phenotype-Driven Approach

Background/Objectives: Young-onset ischemic stroke shows substantial etiologic heterogeneity. However, the value and diagnostic yield of advanced cardiac and autoimmune evaluations in young adults remain uncertain. Methods: Patients aged 25–55 years admitted with acute ischemic s...

Association Between Mandibular Anterior Crowding and Gingival Recession Following Orthodontic Treatment: A Retrospective Cohort Study

Background/Objectives: Gingival recession frequently affects the anterior mandibular region. Anatomical features, such as thin buccal bone, narrow keratinized gingiva, and root proximity, increase susceptibility to periodontal disease. Recession can progress over time and may be...

Effects of Diffusion and Delays on the Dynamics of an HIV Infection Model

This paper investigates the effects of diffusion and two time delays on the dynamics of an HIV infection model in one-dimensional domain. The Galerkin method is employed to derived theoretical equations. A condition is established for identifying exact Hopf bifurcation points, fo...

Highly Stable and Scalable Quasi-Solid Blend Biopolymer Electrolytes for High-Performance Supercapacitor Applications

Abstract A biopolymer blend composed of alginic acid and carboxymethyl cellulose was identified as a uniform and stable host matrix (BP) for developing redox-activated polymer electrolytes. However, biopolymer-based electrolytes often face challenges related to stability and larg...

Influence of total occlusal convergence and auxiliary retentive features on regional marginal discrepancy in milled and 3D-printed short provisional crowns—an in-vitro study

This in-vitro study evaluated the influence of total occlusal convergence (TOC) (10°/20°) and auxiliary retentive features (ARF) (groove, proximal box) on regional marginal discrepancy in milled (CopraTemp PMMA) and 3D-printed (Asiga Dentatooth) short (3 mm) provisional crowns (P...

Sphenoid fungal rhinosinusitis across the disease spectrum: a case series of non-invasive fungal ball and fatal acute invasive fungal rhinosinusitis

Introduction: Sphenoid fungal rhinosinusitis is an uncommon but clinically important entity ranging from non-invasive fungal ball to rapidly fatal acute invasive fungal rhinosinusitis. Case presentation: We report two contrasting cases of sphenoid fungal disease. The first was a...

AERO-GUARD: A Post-Quantum Mutual Authentication Drone Protocol with Homomorphic Encryption for Secure Road Surveillance in Smart Cities

This paper presents AERO-GUARD, a formally verified drone authentication and road surveillance system that integrates Kyber post-quantum key encapsulation, physical unclonable functions (PUFs), decentralized IPFS-based identity storage, and blockchain-anchored audit logging. AERO...

Techno-Economic Assessment of PEM Electrolyzer Coupled with High-Concentration Photovoltaics in Saudi Arabia

Green hydrogen (H2) production is a pivotal element of Saudi Arabia’s Vision 2030. This study presents a comprehensive feasibility assessment of a high-efficiency H2 production system integrating a photovoltaic (PV) array and a high-concentration photovoltaic (HCPV) system with a...

Institutional support mechanisms associated with teacher empowerment and professional commitment among primary and secondary school teachers in urban schools in Mogadishu, Somalia

Teacher empowerment and professional commitment are important for supporting educational quality, particularly in fragile and post-conflict contexts where institutional support structures remain weak. Despite increasing attention to teacher retention challenges in developing coun...

The effect of high-fidelity simulation with live actors on nursing students’ communication self-efficacy: a pre-post intervention study

Effective communication is essential for safe and patient-centered care, particularly in intensive care units (ICUs), where interactions with critically ill patients and their families are emotionally demanding. Nursing students often lack confidence in such high-stakes communica...
