Summary: This review summarizes the research conducted so far on cement-based composites reinforced with waste paper-based cellulose fibres, focusing on their composition, mechanical properties, and durability characteristics. The properties of the raw materials significantly affect the formation of the cement composite binders. Silica and magnesium compounds have positive effects on the setting of the cement composite when combined with waste paper cellulose fibres. The dispersion of fibres in the matrix is crucial for developing composites with well-balanced mechanical properties using waste paper cellulose fibres. Water quantity plays a role in improving fibre dispersion, but higher porosity and voids affect the strength properties beyond an optimum water-to-cement ratio.

Summary: This article proposes a new correlation to estimate the convective heat transfer coefficient inside the evaporation chamber of a single slope solar still with a low humidity level. Existing models neglect the effect of vapour pressure and fail to accurately predict the convection in higher water temperatures or in unsaturated humidity levels. The new correlation, based on a theoretical approach and experimental data, shows improved accuracy in predicting daily water yield under different humidity levels and aspect ratios.

Summary: Recycled glass is a sustainable alternative to sand in concrete, but the alkali-silica reaction (ASR) poses challenges for its widespread adoption. This study investigates the long-term ASR expansion of mortar containing glass through experimental and numerical analyses. Experimental results show that the size fraction of 1.18-2.36 mm caused the highest ASR expansion, while sizes smaller than 0.6-1.18 mm were found to be innocuous. The validated numerical model accurately predicts ASR expansion and reveals that internal damage becomes more homogeneous with increasing content of reactive aggregate.

Summary: The revolution of immobilization material has evolved from traditional plaster to modern synthetic casting tape since 3000 BCE, driven by the search for superior casting material with excellent properties in mechanics, load-bearing, non-toxicity, healing rates, patient satisfaction, and eco-friendliness. Traditional plaster remains a popular choice due to skin conformability, low cost, and availability, while synthetic material can cause complications such as compartment syndrome and deep vein thrombosis. This paper provides a comprehensive review on immobilization techniques, existing materials, and associated complications, aiming to assist medical practitioners and researchers in improving and selecting casting materials.

Summary: This study compares different scenarios for processing waste photovoltaic panels at the end of their life in Australia, including landfill, traditional recycling, full-recovery, and modified full-recovery. Environmental and financial analyses were conducted using simplified methods. The results show that landfill is no longer the cheapest option due to increasing waste levies and landfill bans, and recovering more waste through full-recovery has the potential to save costs. The study also found that modified full-recovery has environmental benefits and focusing on reclaiming solar-grade silicon can generate higher revenue compared to traditional full-recovery.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.
