Degradation and Decay of Rocks: Linking Wetting–Drying and Slake Durability Tests for Climate-Sensitive Maintenance

Geotechnics
Soft and weak rocks present challenges for construction activities in various environments. Their genetic origin, geological and tectonic evolution, and exposure to atmospheric conditions control their weathering and degradation over time.

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

Archaeometry, Volume 68, Issue 3, Page 421-433, June 2026.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

Severity of Betel Quid Use Disorders (BUD) Among Adult Indian Betel Quid Chewers

Oral Diseases, Volume 32, Issue 6, Page 1544-1555, June 2026.
ABSTRACT Objective Oral cancer is a major public health problem in India, with the highest number of cases and deaths in the world, and Betel Quid (BQ) chewing is responsible for almost 50% of cases. BQ Use Disorder (BUD) prevalence and severity have never been investigated among Indian BQ chewers.

Observations from large-scale triaxial compression tests at jointed slaking rock masses [PDF]

EPJ Web of Conferences
Triaxial compression tests are commonly used to characterise strength and deformation behaviour of rock to determine parameters for engineering design and modelling. For triaxial tests, intact specimens are usually selected to determine parameters of the

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Application of geological strength index for characterization of weathering-induced failures

Građevinar, 2018
This study investigates weathering induced failures of the heterogeneous fissile rock mass consisting of sandstone and shale. Discontinuity data was collected and the geological strength index (GSI) value was determined immediately after excavation based

Simple soil health management indices to evaluate row crop management

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Numerical expression of agronomic practices will improve the communication and scientific evaluation of soil health management systems. The development of simple indices computed from management data to evaluate effects on soil health could improve communication with on‐farm and off‐farm stakeholders about practice adoption.
