Red Fox Optimization-Based Estimation Algorithms for Splitting Tensile Strength of Basalt Fiber Reinforced Concrete

Journal of Applied Science and Engineering
To address the limited availability of literature on the splitting tensile strength (STS) of basalt fiber reinforced concrete (BFRC), it is necessary to create and evaluate approaches for predicting STS.

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, EarlyView.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Sequestration of CO2 by concrete and natural minerals - current status, future potential, and additional benefits

Circular Agricultural Systems
Concrete structures are some of the largest constructions in human civilization. Their manufacture releases CO2 into atmosphere, which is partially readsorbed by standing structures, and further release occurs when they are demolished.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
