Assessing the applicability of a special model of plutonium behavior in presence of chelates in cases of wound intake of industrial compounds of plutonium in the FSUE Mayak PA workers

Радиационная гигиена
In cases of intake of higher levels of plutonium, a chelate diethylenetriaminepentaacetic acid is used to enhance the elimination and reduce deposition rate in the organs of major deposit in the form of calcium compound Ca-DTPA (pentacinum). To interpret

Talc‐Tempered Pottery From Bala Hissar, Kabul: An Analytical Study

Archaeometry, EarlyView.
ABSTRACT Potsherds of cooking ware excavated at Bala Hissar archaeological site in Kabul were studied using X‐ray fluorescence (XRF), scanning electron microscope‐energy dispersive X‐ray spectrometry (SEM‐EDS), Raman spectroscopy, X‐ray powder diffraction (XRPD), thermogravimetric analysis (TGA) and optical microscopy.

Palaeoglaciations in the Polar and Subpolar Ural Mountains

Boreas, EarlyView.
The Ural Mountains form a major physiographic boundary between the East European Plain and West Siberia, both repeatedly glaciated during the Pleistocene by the Barents–Kara ice sheet. Although the present‐day topography reflects significant glacial modification, the extent, chronology and interaction of mountain glaciers with the Barents–Kara ice ...

Comparative analysis of inductively coupled plasma mass spectrometry and alpha spectrometry methods to measure plutonium activity in biosubstrates

Радиационная гигиена
Currently, the most common methods to measure the activity of transuranium elements in biological samples are alpha radiometry and alpha spectrometry. Of these, alpha spectrometry is the most sensitive and selective method.

Morphometric analysis of cirques in central Siberia's western Putorana Plateau: a proxy for palaeoclimate

Boreas, EarlyView.
A detailed morphometric analysis of 200 cirques across the western Putorana Plateau, central Siberia, was undertaken to investigate cirque development, reconstruct glaciers and infer palaeoclimatic conditions. Cirques are amphitheatre‐shaped landforms with mean length and widths of 936 and 1000 m, respectively, indicating a mature glacial landscape ...

Areas of high risk for mammalian biodiversity and nature's contributions to people under global warming

Conservation Science and Practice, EarlyView.
Climate change has reached unprecedented levels, causing frequent extreme events like droughts and fires. These changes are driving a sharp rise in extinction risk for mammals and threatening key Nature's Contributions to People (NCP) such as clean water, air quality, and climate regulation.

Climatic, biogeographic and ecological factors influence the spatial patterns of odd‐ and even‐year dominance in biennial European butterflies and burnet moths

Ecological Entomology, EarlyView.
250,000 observations of 7 annual, 11 biennial and 4 flexible lepidoptera species in the Alps and over 150,000 observations of 5 biennial species from Scandinavia were analysed. Maps show distinct patterns of different species that fly predominantly in odd or even years in the researched areas.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space

Journal of Regional Science, EarlyView.
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...
