Research into the factors of transfering radionuclides from soil to the components of fruit trees / Radionuklidų pernašos faktorių iš dirvožemio į vaismedžių sandus tyrimas

Mokslas: Lietuvos Ateitis, 2011
The study reveals the factors of transferring radionuclides 137Cs, 40K and 232Th from soil under fruit trees to the components of fruit trees. Three fruit trees growing in two different places were chosen.

Measurement of neutron-induced fission cross sections of 232Th from 1 to 300 MeV at CSNS Back-n

Physics Letters B, 2023
232Th/233U fuel cycle is an alternate candidate for future nuclear energy. Neutron-induced fission cross section of 232Th is one of the important nuclear data if using thorium as the fuel in the future.

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

Geological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Effects of Transition Metals (TM = Nb, Ta, and Zr) on Thermodynamic and Electronic Properties of Advanced (Th1−xTMx)C (x = 0.1 and 0.2) Fuels: A First‐Principles Study

Materials Genome Engineering Advances, EarlyView.
First‐principles study reveals Zr‐doped ThC maintains superior thermal conductivity and rigidity; Ta‐doping induces structural softening, whereas Nb enhances covalent bonding. These atomic‐scale insights guide the design of advanced thorium‐based nuclear fuels with tailored thermomechanical properties.

U–Th isotopic microanalysis of zircon reference materials and KBSI working standards

Journal of Analytical Science and Technology, 2018
Background The 238U–230Th disequilibrium dating of the mineral zircon (ZrSiO4) provides an efficient tool for investigating the time scales of Quaternary magmatic processes.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.
