The hydrogen isotope (2H/1H) ratio of lipids from phytoplankton is a powerful new tool for reconstructing hydroclimate variations in the geologic past from marine and lacustrine sediments. Water 2H/1H changes are reflected in lipid 2H/1H changes with R2 > 0.99, and salinity variations have been shown to cause about a 1‰ change in lipid δ2H values per unit (ppt) change in salinity. Less understo...

In the 2019 C38 Deuterium-Deuterium campaign at JET several different ITER-relevant materials and dosimetry foils were irradiated in a specially designed long-term irradiation station located inside vacuum vessel with purpose of testing activation ITER by fusion neutrons. The samples exposed to neutron fluence 1.9E14 n/cm 2 during discharges performed experimental over period 5 months. Gamma ra...

The purpose of the study is to identify socio-psychological challenges that influence distance learning education performance be recognized and evaluated in COVID-19 pandemic situation develop planning utilization strategy for smooth high-quality online uninterrupted teaching environment future. A systematic random sampling survey method used collect information from 100 respondents on a ten-po...

Divertor monitoring pulses (DiMPle) have been run in JET from the C35 campaign onwards. They provide an opportunity to study impurity contamination of plasma when it is limited by different surfaces within machine, as well longer term behaviour impurities. In these discharges first on outer wall, then inner wall and, subsequently, X-point configuration strike point positioned horizontal tile 5 ...

The alkenone paleothermometer, U37K′, has been used to estimate past sea surface temperatures (SST) for nearly forty years. Despite its popularity, U37K′ is conventionally limited water between 5 and 28.5 °C. At both low high temperature ranges [0–8; >24 °C], displays nonlinear behavior significant scattering, leading major uncertainties in reconstructed SSTs. With data from 171 sediments acros...
