Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)

X-Ray Spectrometry, EarlyView.
ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Depth‐resolved X‐ray residual stress analysis on samples with cylindrically shaped surface topography

Journal of Applied Crystallography, EarlyView.
Modifications of the fundamental equation of X‐ray stress analysis are proposed that allow correction of the hoop and longitudinal stresses obtained from sin2ψ measurements on samples featuring an inhomogeneous surface topography. The formalism is verified by angle‐ and energy‐dispersive measurements performed on a ferritic steel sample with ...

Enhancing microstructural fidelity in near‐field high‐energy diffraction microscopy reconstruction with Noise2Void denoising

Journal of Applied Crystallography, EarlyView.
A self‐supervised deep learning model, Noise2Void (N2V), denoises near‐field high‐energy diffraction microscopy diffraction images without requiring unobtainable clean data. These images allow for lower segmentation thresholds and detection of smaller and weaker diffraction peaks, which are often discarded or overlooked with conventional image ...

Elliptical neutron‐focusing supermirrors with Ni–P‐plated Al–Si alloy substrates for multi‐incident‐angle neutron reflectometry

Journal of Applied Crystallography, EarlyView.
Multi‐incident‐angle neutron reflectometry is realized using elliptical metallic supermirrors for dual‐beam focusing. This approach presents new opportunities for efficient interface analysis.This study introduces a novel approach for multi‐incident‐angle neutron reflectometry utilizing metallic elliptical supermirrors to enable the simultaneous ...

State of the Field: Royal Studies and Court Studies

History, EarlyView.
Abstract Monarchy, as the world's oldest and most enduring form of political organization, is an area that has attracted the attention of scholars from a range of disciplines. Two connected and complementary fields embody this interdisciplinary study of monarchy and monarchies: royal studies, which takes an all‐encompassing approach to monarchy, and ...
