Evaluation of the Prevalence, Perception, and Factors Associated with Obesity Among Pharmacy Students

Background: Obesity is a growing public health concern among university students and is influenced by lifestyle and behavioral factors. This study assessed the prevalence of being overweight and obesity and their associated lifestyle factors among pharmacy students. Methods: A cr...

LightZK: An Efficient GPU Acceleration Framework for Large-Scale Zero-Knowledge Proofs

Zero-Knowledge Proofs (ZKPs), particularly zk-SNARKs, have become a cornerstone for privacy-preserving protocols and blockchain scalability. However, the generation of proofs remains computationally prohibitive due to the immense overhead of underlying cryptographic primitives, n...

Integrating Landsat 8 remote sensing and machine learning for water quality assessment in a tropical river basin

Artisanal and small-scale gold mining (ASGM) has degraded river water quality in sub-Saharan Africa, while conventional monitoring remains constrained by cost and logistical challenges. This study integrates Landsat 8 OLI multispectral imagery with machine-learning regression to...

Green-synthesized gold nanoparticles from Omani pomegranate peel: Phytochemical characterization and antileishmanial activity

Omani pomegranate peel is a rich source of phenolic compounds with antioxidant and antimicrobial properties, making it a promising source of antiparasitic bioactive compounds. This study compared air-dried (PPE1) and oven-dried (PPE2) Omani pomegranate peel extracts, chemically s...

Integration of Quality Function Deployment and Monte Carlo Simulation for risk prioritization in a textile sector

Purpose Following the COVID-19 pandemic, the home-textile industry has experienced a decline in production orders, heightening competition and making it more difficult to maintain consistent customer satisfaction and operational performance. To address these challenges, this stud...

A simple reverse current blocking circuit

When the direction of system current is opposite to the normal operating direction, it is called reverse current. Causes include reverse battery connection, multiple power supply parallel connection, the car starting process, etc. For example, in a battery application, if the bat...

Prevalence of Delayed Healthcare Presentation and Associated Factors in Patients with Predominantly Mild Traumatic Brain Injury: A Systematic Review and Meta-Analysis

Background/Objectives: Traumatic brain injury (TBI) is a global burden and a leading cause of death and disability worldwide. Delayed healthcare presentation is significantly associated with poor outcomes. This systematic review and meta-analysis aim to estimate the prevalence of...

Sustainable development of lignin-based biodegradable coating from palm tree waste for aluminum foil applications

Abstract The environmental challenges presented by synthetic, non-biodegradable coatings used in aluminum packaging have accelerated the search for sustainable alternatives. This research aimed to develop and optimize biodegradable lignin-based coatings derived from Date Palm Emp...

From redox chemistry to device integration: next-generation supercapacitors engineered from metal telluride, sulfide, and selenide heterostructures with MXenes and MOFs comparison, progress, challenges, and prospects

Metal chalcogenides, including tellurides, sulfides, and selenides, have become promising materials for high-performance supercapacitors due to their redox activity, high theoretical capacity, and tunable structures. This review discusses challenges, architectural design, synthes...

Radiological Hazard Assessment of Naturally Occurring Radioactive Materials in the Hwange Mining Area, Zimbabwe: A Gamma Spectrometric Study

The Hwange Mining Area, located in the Mid-Zambezi Karoo Basin in northwestern Zimbabwe, is a major centre for coal mining, processing, and thermal power generation. This study evaluates the ecological and public health risks associated with these activities by characterising rad...

Effect of Omani Limestone Waste as a Reinforcing Agent on the Mechanical Properties of Scrap-Based Aluminum Matrix Composites

This paper analyzes the use of Omani limestone, collected from the mountain ranges of the Sultanate of Oman, a major global exporter of limestone, as a natural reinforcement to improve the mechanical properties of recycled aluminum alloys obtained from automotive engine cylinder...
