Machine learning and Weibull-based reliability analysis of impact-resistant geopolymer concrete with construction demolition waste and natural fibers

This study presents a novel impact-resistant geopolymer concrete (GPC) incorporating construction and demolition waste powder, brick waste powder, slag, recycled concrete aggregates (RCA), and natural fibers (banana, jute, and pineapple) to simultaneously enhance its mechanical p...

Modeling Sustainable Natural Resource Consumption and Its Impact on Economic Growth: An Empirical Study of Africa and Asia

ABSTRACT The utilization of natural resources plays a crucial role in economic development and enhancing social welfare. This study aims to empirically explore the effect of natural resource rents on economic growth to test whether natural resources are a curse or a blessing for...

Sustainability as a driver of customer choice: evidence from SMEs in Oman

Purpose This study investigates the impact of sustainability practices on customer choice in the context of small and medium-sized enterprises (SMEs) in Oman. It further examines the roles of customer trust and subjective norm in explaining how sustainability practices influence...

Improved Soft Rough Set Covering Model for Wireless Indoor Localization: Modeling and Accuracy Analysis

Indoor localization based on Received Signal Strength (RSS) fingerprinting remains a prominent paradigm owing to its economic viability and seamless integration with existing wireless infrastructure. Nevertheless, positioning accuracy is frequently compromised by spatiotemporal e...

PVA-based hydrogels for chronic wound healing: a systematic review of mechanical, structural, chemical, and biological performance

Abstract Polyvinyl alcohol (PVA)-based hydrogels are promising chronic wound dressings owing to their tunable structure, biocompatibility, and capacity to carry bioactive agents. Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline, t...

A Secured Parallel Multi-Broker MQTT Framework with Chaos-Enhanced Hybrid Encryption for Repetition-Resistant IoT Security

The proliferation of IoT deployments has exposed critical vulnerabilities in MQTT-based systems, particularly ciphertext-repetition leakage in telemetry encryption, where identical plaintext blocks under a fixed key—common for static sensor readings—collapse ciphertext entropy an...

The nexus of sustainability: investigating energy transition, green technological innovations, and financial development in mitigating carbon emissions in BRICS

Purpose From the perspective of global environmental stability, the BRICS’ position as the world's leading carbon emitter poses a serious threat. Therefore, it is essential to develop a distinct model that enables policymakers to formulate robust mitigation strategies and support...

The purpose of this study is to examine factors that impact the sustainability of the organizations in the engineering, electrical and information technology in Jordan and examine the moderating role of digital leadership. The data of 396 leaders were collected and analyzed using...

The Impact of Leadership Styles on Turnover Intention: Perceived Supervisor Support as A Mediator in The Jordanian Public Universities

The present study aims to investigate the effect of authentic, inclusive, strategic, and laissez-faire styles of leadership on turnover intention among academic staff in public universities in Jordan, through the mechanism of Perceived Supervisor Support (PSS). A total of 367 res...

Advanced Strategies for Comfort and Mechanical Performance of 3D-Printed Concrete Wall Structures: A State-of-the-Art Review

3D-printed structures are an important direction in green construction, but layer-wise deposition forms interlayer interfaces that strongly influence the axial compressive performance of printed walls. This paper reviews interlayer bonding, anisotropy, strengthening strategies, a...

A review of object detection methods: lightweight and energy-efficient detectors

Object detection means finding and naming objects inside an image or a video. Today, making these models lightweight and energy-efficient is very important. This is because we want to run them on small devices like smartphones, drones, and smart cameras that have limited battery...

PerspectiveReview on Ammonia and Methanol: The Next-GenerationMarine Fuel for the Shipping Industry

Abstract The shipping industry is one of the leading contributors to greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has set ambitious targets under its 2023 GHG strategy, including reducing the carbon intensity by 40% by 2030 and achieving net-zero...

Parental Awareness and Readiness in Supporting Phonics Learning among Lower Primary ESL Pupils: A Conceptual Framework for Home Literacy Support

HRMARS - Early literacy development is crucial for learners’ academic success, especially during the lower primary years when reading skills are formed. Phonics instruction is a key part of early literacy, aiding children in decoding and recognising words. While schools offer for...

Valorization of slag and banana leaf ash in five natural fiber-reinforced sustainable cementitious composites: early age mechanical and microstructural insights

Portland cement is highly energy-consuming, and its CO 2 emissions raise environmental concerns in the construction sector. This has prompted the desire for sustainable additional cementitious materials, such as slag and banana leaf ash (BLA). Nevertheless, the current literature...
