Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Development and Recovery of Stress‐Induced Elastic Anisotropy During Cyclic Loading Experiment on Westerly Granite

open access: yesGeophysical Research Letters, 2018
In the upper crust, where brittle deformation mechanisms dominate, the development of crack networks subject to anisotropic stress fields generates stress‐induced elastic anisotropy.

THE KAISER EFFECT OF GRANITE CAUSED BY VARIOUS LOADING METHODS

open access: yesDoboku Gakkai Ronbunshu, 1985
In order to know the Kaiser effect of AE (Acoustic Emission) in triaxial directions of a rock mass, the Kaiser effect of AE in the granite specimens were investigated by applying the compressive pre-stresses of various intensities repeatedly on the respective directions to the specimens.From the testing results, it was found that the pre-compressed ...

Self‐ and Caregiver‐Reported Choice‐Making in Autistic Adults: Development and Validation of the AASPIRE–Choices and Decisions Scale

open access: yesAutism Research, EarlyView.
ABSTRACT Self‐determination has been assessed as an internal psychological construct. External factors may also affect self‐determination, but opportunities to make choices and decisions remain understudied. We developed and evaluated the AASPIRE‐Choices and Decisions Scale (AASPIRE‐CDS), a new measure of autistic adults' opportunities to make choices ...

Mechanical Behaviour of Rock Samples with Burst Liability Under Different Pre-Cycling Thresholds

open access: yesApplied Sciences
To study the influence of the main roof period pressure on the instability mechanism of rock pillars with burst liability, the composite loading mode of “pre-cycling loading + continuous loading with a constant rate” was used to conduct compression ...

Blood pressure effects of SGLT2 inhibitors and GLP‐1 receptor agonists: Mechanisms, trial evidence and Real‐world data

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.

Crack evolution and Kaiser effect in red sandstone from cold regions under synergistic freeze–thaw and cyclic loading

open access: yesInternational Journal of Mining Science and Technology
The progressive deterioration of rock slopes in cold regions, driven by seasonal freeze–thaw (F-T) cycles and repeated mining-induced disturbances, poses a significant threat to the long-term stability of engineering infrastructure.

The epistemic ceiling: Veteran practitioners' perspectives on primary qualification entry standards for teaching secondary mathematics in Scotland

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper presents an exploratory analysis of contemporary curricular and professional qualification policies in the Scottish education system, focusing on minimum qualification thresholds for mathematics teaching. The study examines how veteran secondary mathematics practitioners perceive the structural and pedagogical implications of using ...

Acoustic Emission Monitoring of Industrial Facilities under Static and Cyclic Loading

open access: yesApplied Sciences, 2018
Acoustic emission (AE) testing is traditionally carried out on non-operating objects. Such requirement is associated both with the Kaiser effect, leading to the necessity for exceeding the test load above the working one and with a high level of noise ...
