How interference between the North Atlantic Oscillation and the tropical Indo‐Pacific convection modulates wave trains along the subtropical jet: Impacts on the Asian winter climate

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in

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 ...

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

Scaling relationships between Haversian canal‐to‐secondary osteon and midshaft femur cortical‐to‐total area in a human autopsy sample

Journal of Anatomy, EarlyView.
We report that femoral cortical thickness was strongly and negatively associated with secondary osteon porosity in an Australian autopsy sample, indicating that thicker cortices contained less porous secondary osteons. This allometric relationship held for the whole sample, males and sedentary well‐nourished individuals, but not for females or other ...

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.
