    Connecting the dots between subjective norms, perceived ease of operational use, and intention towards shaping AI adoption strategies for talent acquisition across supply chains
    (October University for Modern Sciences and Arts MSA , Faculty of Management Sciences, 2025) Eman Hassan Rajab; Heba Mohamed Adel; Muhammad Salah Nafea3
    Abstract This study aims to conceptually and empirically investigate the role of subjective norms (SN) and perceived ease of operational use (PEU) in influencing the behavioral intention (BI) of human resources (HR) professionals to adopt artificial intelligence (AI) strategies for talent acquisition within the Egyptian banks and across their supply chains. This study applied a quantitative approach by surveying 100 HR professionals within various banks in Egypt through a snowball sampling technique. The hypotheses were subsequently tested using structural equation modeling (SEM). The results indicate that SN and PEU play a significant role in shaping the BI towards AI adoption among HR professionals in the Egyptian banking sector. The findings of this study produce several remarkable multidisciplinary practical implications for AI technology experts, strategic human resources leaders and operations and supply chain managers to develop effective strategies for AI adoption in the Egyptian banking sector and other similar industries and countries. Thereby, this multidisciplinary research contribution is resulted from the integration of the literature of technology adoption (i.e., AI adoption), human resources management (i.e., talent acquisition), and strategic, operations, and supply chain management (i.e., developing functional strategies encompassing the adoption of AI systems with an ease of operational use within organizations and across supply chains).

    Fluorinated graphene-modified biodentine: an in vitro study on its ion release, cell growth, differentiation potential, and compressive strength
    (BioMed Central Ltdw, 2025-10-31) Fagr Hassan Elmergawy; Iman Ahmed Fathy; Zeinab Mahmoud Abulwafa; Ghada Ahmed Elzayat; Heba Mahmoud Seif
    Objectives: This study evaluated Biodentine (BD) after modification with 2 wt% fluorinated graphene (FG). Methods: FG was prepared using the modified Hummers’ method, where sulfuric and phosphoric acids were added to fluorinated graphite and potassium permanganate. The mixture was heated, sifted, filtered, and centrifuged to obtain FG powder. Characterization was performed using XRD, FTIR, TEM, and SEM/EDX. PH was evaluated, And Ca And F ion release were assessed by inductively coupled plasma spectroscopy and ion chromatography, at days 1,14, And 28. Cell viability was performed using the MTT Assay on pulp stem cells, while ALP assay was evaluated by a spectrophotometer. Compressive strength was evaluated by a universal testing machine. Statistical analysis was performed on the data (p ≤ 0.05). Results: Graphene and C-F bonds of FG were confirmed in XRD and FTIR, while nanosheets were detected in TEM. SEM/EDX showed more surface roughness in modified BD-FG. pH And Ca ion release results showed significantly higher values at day 1 for modified BD-FG, with significantly higher cumulative Ca ion release. Cell viability results showed no significant difference between modified And unmodified Biodentine at days 1 And 7; however, modified BD-FG showed significantly lower values at day 3. No significant difference was observed between the two groups in ALP, while the BD-FG group showed significantly higher compressive strength. Conclusion: Incorporating 2 wt% FG into BD increases ion release, hydroxyapatite formation, and mechanical properties without compromising cell viability and differentiation. Clinical relevance: The addition of FG enhanced the bioactivity of Biodentine and improved its strength without showing cytotoxicity, making it a promising approach that needs further study.

    Bridging tradition and innovation: a framework for implementing sustainable Design-Build Studios in Middle Eastern architectural education
    (Frontiers Media SA, 2025-10-21) Nermine Abdel Gelil Mohamed; May Adel Ebaid
    This paper develops and validates the first systematic framework for implementing Design-Build Studios (DBS) in Middle Eastern architectural education. It attempts to close the long-standing gap between theoretical knowledge and practice by aligning regional cultural, environmental, and educational needs with Western design-build precedents. The study follows a multi-stage mixed-methods approach combining the synthesis of systematic literature, framework development, and empirical validation through a detailed survey of 61 regional stakeholders distributed across Egypt, Gulf states, the Levant, Iran, and Turkey. The empirically validated framework sequences DBS implementation into three enabling modules (Curriculum, Studio, People) along three successive stages (Implementation, Operation, Maintenance) with clear integration of Heritage, Sustainability, and Innovation themes. Stakeholder validation records overwhelming regional acceptance (85.2% positive rating) and identifies critical implementation priorities: funding security (67.2% ranked as highest priority), resource availability (59.0%), and participant preparation (54.1%). Regional sustainability priorities are water scarcity (72.1%), affordable housing (68.9%), and heritage preservation (68.9%), which differentiate Middle Eastern requirements from Western precedents. The framework transforms from a conceptual, culturally-adaptive pedagogical model into an empirically-weighted readiness tool that allows systematic institutional assessment across five critical domains (30% funding and feasibility, 20% facilities and resources, 20% community and people, 15% curriculum integration, 15% maintenance and reflection), providing institutions with quantifiable assessment capabilities and prioritized implementation recommendations. This study forms the foundation of DBS implementation, an evidence-based practice where Middle Eastern architectural education can leverage global pedagogic innovations. These are systemically adapted to regional conditions via stakeholder engagement, cultural awareness, and equipping students for the future realities of sustainable and socially responsible architectural practice.

    Biochemical and histological evaluation of a novel Lactiplantibacillus plantarum strain as a promising probiotic therapy for treating IBD induced by acetic acids in rats
    (Springer Nature, 2025-10-16) Amira Abdeldaim; Ahmed Samir
    Inflammatory bowel disease (IBD) is a chronic gastrointestinal condition with significant impacts on quality of life. Current treatments, including anti-inflammatory drugs and immunosuppressants, often cause severe side effects, emphasizing the need for safer alternatives. Probiotics offer a promising therapeutic option due to their ability to modulate gut microbiota and reduce inflammation. This study evaluates the prophylactic and therapeutic potential of a novel Lactiplantibacillus plantarum C4 strain, isolated from milk, in an acetic acid-induced IBD rat model. Rats were divided into five groups, five animals each. Animal groups were negative control, positive control (induction only), and three treatment groups receiving sulfasalazine, a commercial probiotic, or the novel Lactiplantibacillus plantarum C4 strain. Efficacy was assessed through histological examination and biochemical analysis, including inflammatory biomarkers (IL-6, IL-1β, TNF-α) and oxidative stress markers (superoxide dismutase, catalase, and malondialdehyde). The novel Lactiplantibacillus plantarum strain demonstrated comparable effectiveness to sulfasalazine in mitigating histological damage, reducing inflammatory marker levels, and restoring antioxidant enzymes activity. These findings suggest that the novel Lactiplantibacillus plantarum C4 holds significant promise as a safe, effective and accessible therapeutic option for IBD.

    A Camouflage Fire Sprinkler Antenna for Indoor Sub-6 GHz 5G and WiFi Applications
    (IEEE, 2025-10-14) Ahmed Alieldin; Abdelrahman M. El-Akhdar; Angie R. Eldamak; A. M. Elelimy Abounemra; Mohammad Darwish
    This paper proposes a novel design of a camouflage antenna for sub- 6GHz5G and WiFi applications. The antenna structure typically implies the shape of a fire sprinkler to achieve sufficient camouflage so that it is less conspicuous to the users. The antenna achieves a fractional bandwidth of 20 % covering the frequency band from 2.25 GHz to 2.75 GHz with a return loss better than 10 dB(VSWR≤2). This broadband is achieved due to the structure flare angle, which contributes to forming the shape of the fire sprinkler. The antenna has a high stable gain of 9.5 dBi and half-power-beam widths of 70° and 65° at the Eplane and H-plane, respectively. These results along with the antenna shape make the proposed antenna a good candidate as a camouflage antenna for indoor sub- 6 GHz 5 G and WiFi applications.
