Reimagining sustainable education in Africa through decolonial pathways and indigenous knowledge systems

Despite the growing recognition of Indigenous Knowledge Systems (IKS) as vital for the sustainability of education in Africa, the majority of education systems across the continent still embody colonial epistemologies that marginalise local knowledge traditions. Existing literatu...

Adsorption of hazardous Acid Violet 17 on Vachellia nilotica biochar: experimental and statistical physics modelling

Abstract Inadequate management of chemical industrial effluents necessitates the development of high-capacity, sustainable wastewater treatment technologies. This study investigates the adsorptive removal of hazardous Acid Violet 17 (AV17) dye using a novel biochar derived from V...

On (N1)-Tuple Riccati Stability+

In this paper, we introduce the notion of tuple Riccati stability, which extends the classical concept of Riccati stability from a pair of matrices to an arbitrary finite collection of matrices. We establish an equivalent linear matrix inequality characterization and investigate...

The Effect of ESG Controversies on Corporate Financial Performance: Evidence from US Listed Firms

This study examines the association between environmental, social and governance (ESG) controversies and the subsequent financial performance of firms listed in the United States and whether the information environment of the firm conditions this association. Most of the literatu...

Circular Economy Readiness and Sustainable Value Creation: A Moderated Mediation Model of Green Intellectual Capital and Environmental Uncertainty

ABSTRACT This paper examines the relationship between circular economy readiness (CER) and sustainable value creation (SVC), as well as the mediation between CER‐SVC by green intellectual capital (GIC) and the moderation between CER‐SVC by environmental uncertainty (EU) in the co...

Heat and mass transfer analysis in magneto-electroosmotic Oldroyd 8-constant fluid flow through a serpentine passage: a comparative FDM-CSCM analysis under convective and soret effects

In this draft, an analysis is carried out for Hall currents and variable transport characteristics in an electro-osmotically driven flow inside a serpentine wavy channel. The Oldroyd 8-constant model, along with heat and mass transfer, is taken into account. Assuming a low zeta p...

Oncology nurse navigator core competencies and patient satisfaction

Oncology nurse navigators (ONNs) are increasingly recognized for their vital role in improving the quality of cancer care by supporting patients throughout their treatment journey. In Egypt, nurse navigation implementation remains limited, and empirical evidence examining the rel...

Holistically benchmarked optimization-assisted green spectrophotometric–chemometric approach for simultaneous determination of piroxicam and venlafaxine in pharmaceutical formulations and spiked human plasma

The recent clinical introduction of the piroxicam (PIR) and venlafaxine hydrochloride (VEN) combination has highlighted the need for analytical methodologies capable of simultaneously quantifying both drugs while minimizing the environmental burden of routine pharmaceutical analy...

Green-Synthesized CuO Nanoparticles from Pomegranate Peel for Dual Electrochemical Detection and Adsorptive Removal of Tetracycline

Green nanomaterials have attracted considerable attention for environmental monitoring due to their sustainability and multifunctional properties. In this study, copper oxide nanoparticles were synthesized using pomegranate peel (pp) extract (CuO@PP) as a reducing and stabilizing...

A dynamic explainable AI framework for real-time intrusion detection and automated alert prioritization in security operation centers

Abstract Security Operation Center (SOC) analysts face 50–100 security alerts per hour, leading to cognitive fatigue and delayed incident response. Existing intrusion detection systems (IDS) suffer from high false-positive rates and opaque black-box architectures that erode analy...

The Impact of Preexisting Cardiac Implantable Electronic Devices on the Safety of Transcatheter Tricuspid Valve Interventions: A Systematic Review and Meta-Analysis

Background: Tricuspid regurgitation (TR) increases mortality but remains undertreated due to high surgical risks. Transcatheter tricuspid valve interventions (TTVI) offer safer alternatives, improving functional status and quality of life. However, many candidates for TTVI have t...

Algorithm-based approach to the management of rhino-maxillary mucormycosis: part II of a two-part study

Rhino-maxillary mucormycosis (RMM) is an aggressive, life-threatening fungal infection associated with substantial morbidity and mortality. While early diagnosis is universally advocated, robust quantitative evidence delineating how defined diagnostic delays influence objective c...

Generalized lateral, rocking, and coupling stiffness equations for offshore wind turbine monopiles in clay

Harnessing wind energy from deep waters presents unique challenges for foundation design. These challenges arise from the potential for high bending moments and lateral loads, which must be managed while adhering to strict rocking limitations and natural frequency requirements. T...
