Recycling Quarry Dust as a Supplementary Cementitious Material for Cemented Paste Backfill

Quarry dust (QD) landfill causes environmental issues that cannot be ignored. In this study, we systematically explore its potential application as a supplementary cementitious material (SCM) in cemented paste backfill (CPB), revealing the activated mechanism of modified QD (MQD) and exploring the hydration process and workability of CPB containing QD/MQD. The experimental results show tha...

The Impact of Social Media Disorder, Family Functioning, and Community Social Disorder on Adolescents’ Psychological Distress: The Mediating Role of Intolerance to Uncertainty

Background/Objectives: Adolescent levels of psychological distress are strongly influenced by community, individual, social, and family factors. Family functioning, social media use, and community disorder have shown high predictive value for psychological distress during this critical stage of development. However, these relationships are not always direct and are often mediated by indivi...

Efficiency of Modular Bridge Configurations: A Study on the Structural Stability and Capacity of Single- and Double-Story Modular Bridges

This study investigates the structural performance and load-bearing capacity of single- and double-story modular bridge configurations using both experimental testing and finite element analysis. A full-scale field test was conducted on a 45.7 m double-story bridge subjected to truck loading at ten distinct positions along the span. Midspan deflections and axial strains of key members were...

Conservation of Giant Honey Bee (Apis dorsata F.) for Honey and Beeswax Production and Sustainable Pollination Services

During the past quarter-century, the natural populations of giant honey bees (Apis dorsata) have declined markedly. The loss of nesting sources is one of the many reasons for its decline. This has threatened the pollination services of several agricultural and wild plants in areas of its natural habitat. To sustain pollination services in the natural habitat of this honey bee, conservation...

Laser-Induced Liquid-Phase Boron Doping of 4H-SiC

4H-silicon carbide (4H-SiC) is a cornerstone for next-generation optoelectronic and power devices owing to its unparalleled thermal, electrical, and optical properties. However, its chemical inertness and low dopant diffusivity for most dopants have historically impeded effective doping. This study unveils a transformative laser-assisted boron doping technique for n-type 4H-SiC, employing ...

Wastewater Treatment Using a Combination of Pumpkin seed Waste After Extraction of Essential Oils (Bio-Coagulant) and Ferric Chloride (Chemical Coagulant): Optimization and Modeling Using a Box–Behnken Design

The wastewater treatment involves various techniques at different technological levels. Treatment takes place in several stages, of which coagulation and flocculation are the most important. Most suspended solids are indeed eliminated during this stage by the addition of a coagulant. In this research, bio-coagulant was extracted from pumpkin seed (PS) waste after extraction of the essentia...
