Sensitive Grain-Size Components of Last Glacial Loess on Chinese Loess Plateau and Their Response to East Asian Winter Monsoon

Atmosphere, 2023
Chinese loess provides the most detailed terrestrial records of paleoclimate changes. We employed the grain-size components of aeolian sediments to reconstruct the history of the East Asian winter monsoon (EAWM) on the Chinese Loess Plateau (CLP).

Grain size reduction strategies on Eurofer

Nuclear Materials and Energy, 2018
One of the options currently taken into account for the realization of the first DEMO reactor is the “water-cooled blanket”. This option implies a minimum irradiation temperature for the blanket material in the range of 280–350 °C.

Identification of QTLs for grain size and characterization of the beneficial alleles of grain size genes in large grain rice variety BL129

Journal of Integrative Agriculture, 2016
Grain size is one of the most important agronomic components of grain yield. Grain length, width and thickness are controlled by multiple quantitative trait loci (QTLs).
