Non-noble Metal Oxide Catalysts for CO Oxidation in Humid and Sulfur-Containing Streams: From Activity Competition to Stability Challenges

The efficient removal of carbon monoxide from industrial and vehicular emissions has become a pressing practical challenge, driven by tightening emission standards and growing concerns over ambient air quality. Noble metal catalysts, despite their excellent low-temperature activi...

Prioritising Content for Continuing Education in Non-Invasive Ventilation Care: A Needs Assessment Survey of Intensive Care Unit Nurses

Background: The success of non-invasive ventilation (NIV) depends on bedside nursing judgement, yet nurses report insufficient preparation, and educational content is usually decided before the competencies nurses most need are identified. Objectives: To prioritise NIV competenci...

Platinum Group Metal Recovery from End-of-Life Ammonia Oxidation Catalysts in Oxidative Chloride Media

Platinum group metals (PGMs) are critical raw materials, and their sustainable recovery from secondary sources supports supply security and a circular economy. End-of-life ammonia oxidation catalysts are considered attractive feedstocks due to their high PGM content. A systematic...

Integration of Renewable Energy Sources into Saudi Smart Grids: Challenges, Optimization Strategies and Future Opportunities

Saudi Arabia is making the shift from a centrally controlled electricity system that is based on hydrocarbons to one that is digitally coordinated, in which large-scale solar and wind power, distributed energy resources, storage systems, flexible demand, and power-electronic inte...

A Comprehensive Review on the Antimicrobial Culture Susceptibility Patterns and Intravenous-to-Oral Conversion of Antibiotics

Abstract Antimicrobial resistance is a major challenge in managing bacterial infections, emphasizing appropriate antibiotic selection, culture-directed therapy, and antimicrobial stewardship. This review summarizes antimicrobial culture and susceptibility patterns and examines th...

Cell-free RNA in spent embryo medium for non-invasive assessment of preimplantation embryo quality: a review

Embryo quality assessment of preimplantation was a key step that affects the treatment outcomes of assisted reproductive technology (ART). Conventional morphological grading and time-lapse imaging (TLI) were widely used in clinical embryo selection. However, these methods mainly...

Comparative Toxicity of Antifouling Paint Particle Suspensions and Dissolved Leachates in the Marine Copepod Tigriopus japonicus

Antifouling paint particles (APPs), generated by coating degradation and ship-maintenance activities, are an emerging but poorly characterized source of marine pollution. APPs can release particle-associated and dissolved toxicants, yet their relative contributions to toxicity re...

Is IT Science and Technology (S&T)?

This study examines whether Information Technology (IT) is Science and Technology (S&T) by tracing the formation of IT and its academic and institutional development. IT emerged from information processing and computing and developed into an independent computing discipline amid...

Navigating sustainable performance: the interplay between green dynamic capability, supply chain management, and stakeholder integration

Purpose This study examines the mediating role of green supply chain management practices in the relationship between green dynamic capability and both financial and environmental performance in small and medium-sized enterprises (SMEs) in Ghana, considering different levels of s...

Effects of Traditional Chinese Medicine for Prevention and Management of Dry Eye Disease: A Systematic Review, Network Meta-Analysis and Meta-Regression of Randomized Controlled Trials

Dry eye disease (DED) is a prevalent ocular surface disorder with diverse clinical presentations, yet the comparative efficacy of various Traditional Chinese Medicine (TCM) formulations remains unclear. This systematic review and network meta-analysis evaluated the comparative ef...

A dual-cubic proof of the four-point hyperbolic Atiyah conjecture

The hyperbolic Atiyah conjecture assigns a binary form of degree n-1 to each point of an n-point configuration in hyperbolic three-space and asserts that the resulting forms are linearly independent. We give a complete geometric proof for four points. Starting from Malkoun's dual...

Comparative study of pattern making via single, dual-stage wax injection molding, and additive manufacturing for investment casting of stainless-steel manifold product

Pattern making is a critical stage in investment casting for producing complex components. This study evaluates a novel dual-stage wax injection moulding method against the conventional single-stage process and an additive manufacturing approach. A complex stainless steel automot...

Household cooking fuel choices and their health-economic implications in Eastern Uttar Pradesh: a comprehensive review

The various socioeconomic, cultural, demographic, and infrastructure elements that influence household cooking fuel preferences in Eastern Uttar Pradesh (EUP), India, are examined in this review of the research. Although policy initiatives such as the Pradhan Mantri Ujjwala Yojan...

Calcyon: Design and Validation of an AI-Based Chatbot Framework Integrating Computational Thinking and Self-Regulated Learning in University Calculus Learning

Background The integration of artificial intelligence (AI) into mathematics education has advanced rapidly; however, systematic AI-based chatbot frameworks that integrate computational thinking (CT) and self-regulated learning (SRL) scaffolding within university calculus remain l...

Household selection in the absence of a sampling frame in community-based surveys – comparing satellite image-based approaches for a survey on snakebite envenoming in rural Malawi

Abstract Background Household-level survey data are essential for assessing population health, but creating sampling frames remains challenging in rural areas without administrative data. In preparation for a large community-based snakebite survey, we compared satellite-based met...

Adults with congenital heart disease: the growing impact of acquired cardiovascular risk factors on late mortality.

BACKGROUND AND AIMS: With improved survival, adults with congenital heart disease (ACHD) increasingly face acquired cardiovascular risk factors; however, their impact on late mortality remains incompletely defined. This study aimed to evaluate the contribution of acquired cardiov...

Dicer-independent miR-451a is upregulated in periodontitis and potentiates inflammation by impairing macrophage polarization and SOCS activity
