Objectives This study investigates the effects of Artificial Intelligence (AI)-assisted teaching on student outcomes in Grade 11 Advanced Physics at the Applied Technology School (ATS) in the United Arab Emirates (UAE). The project is in line with UAE’s strategic vision for Smart Learning Education aimed at discerning whether AI-assisted teaching is an effective teaching method relative to traditional teaching by teachers in enhancing student performance. Methods A quasi-experiment using a pre-test and post-test control group design was used to compare AI-supported learning to traditional teaching, as per the Physics curriculum standards of the School. The AI-supported teaching included adaptive scaffolding, feedback, and inquiry-based guiding, whereas the traditional teaching adhered to a standard lecture-based teaching methodology. The pre-test comparisons between groups were established using means (AI group = 72.2%, Traditional group = 71.7%). Results Results of the post-test showed a pronounced performance benefit for students in the AI-assisted learning group (Mean = 18.00) than those in the traditional learning group (Mean = 14.25). The calculated value of the size of the effect (Cohen’s d = 1.21) showed a large result, which is useful in estimating its effectiveness in learning concepts in upper secondary Physics classes using AI-enabled feedback tools. Conclusions AI-assisted learning supported strong pedagogical values in this UAE secondary Physics learning environment, raising levels of achievement as well as fostering increased learning regularity. This study is placed in context by the state of current K-12 learning in STEM-related topics, reflecting upon opportunities as well as challenges in this area, focusing accordingly upon an implementation-aimed integration of teachers’ support in future-ready educational approaches in Gulf-based science-education institutions.

Sulfur concrete (SC), recognized for its sustainability and chemical resistance, faces limitations in mechanical strength and thermal durability. This study investigates the enhancement of SC through the incorporation of biomass-derived activated carbon (BAC) from corn husk and cob, substituting 1 %, 3 %, 5 %, and 7 % of carbide lime by weight. The BAC, characterized by high porosity (91 % carbon content in cob-derived BAC, 74.5 % in husk-derived) and a 100–200 µm particle size, was synthesized via pyrolysis at 400°C. Mechanical testing revealed a 23.9 % increase in compressive strength at 7 % BAC replacement, achieving 52 MPa, outperforming prior SC formulations (25–43 MPa). SEM/EDX analyses confirmed BAC’s role in densifying the microstructure, reducing voids, and improving sulfur-aggregate adhesion. Durability assessments under 12 wet/dry cycles demonstrated enhanced resistance to moisture-induced degradation, with BAC-modified SC exhibiting negligible cracking and < 2 % mass fluctuation. The integration of agricultural waste-derived BAC not only elevates SC’s structural performance but also aligns with circular economy principles by repurposing industrial by-products (sulfur from ADNOC) and agricultural residues. These findings position BAC-SC as a viable, high-performance alternative to conventional concrete in harsh environments, offering quantifiable advancements in sustainability and resilience. • A sustainable method integrates biomass-derived activated carbon (BAC) into concrete, promoting eco-friendly construction. • Fine aggregate is partially replaced with BAC and carbide lime to study strength and durability. • Adding BAC to sulfur concrete boosts compressive strength by 23.9 %, enhancing its load-bearing performance significantly. • BAC addition improves sulfur concrete durability by reducing corrosion and cracking from thermal expansion and contraction.

Background: Mesentric Panniculitis an inflammatory condition that usually present with vague abdominal symptoms such as pain and diarrhea. The ambiguity of the symptoms makes the diagnosis of MP a challenge. Case Report: a twenty five years old lady presented to the emergency room with vague abdominal complaints including pain and loss of appetite along with fever for the last two days. Workup for acute appendicitis was done including a CT scan which showed possible radiological signs of Mesentric Panniculitis.
