The strain state COFFEE FILTER BASKET in 3D space is usually expressed by the conventional method of combining three linear and shear strains.Due to the obvious differences between the first two strains, it is necessary to uncover their properties when describing deformation, studying yield and failure, and developing test apparatus or equipment.Th
Hidden Effects of Seed Quality Breeding on Germination in Oilseed Rape (Brassica napus L.)
Intense selection for specific seed qualities in winter oilseed rape breeding has had an inadvertent negative influence on seed germination performance.In a panel of 215 diverse winter oilseed rape varieties spanning over 50 years of breeding progress in winter-type rapeseed, we found that low seed erucic acid content and reduced seed glucosinolate
Ocean Observations Required to Minimize Uncertainty in Global Tsunami Forecasts, Warnings, and Emergency Response
It is possible that no catastrophe has mobilized the global ocean science and coastal emergency management communities more than the 2004 Indian Ocean tsunami.Though the Pacific tsunami threat was recognized, and a warning system had been in place since 1965, there was no warning system in the Indian Ocean, and almost 230,000 people perished.More b
Generation of a bunched positron beam extracted nonadiabatically from a buffer-gas trap and focused in a free field region
Advanced spectroscopy experiments and new physics experiments with positronium atoms in vacuum will benefit from positronium production in an environment free of magnetic and electrostatic fields.Here, we present a novel scheme for generating a bunched positron beam.The positron bunches are prebunched before extraction from a buffer-gas trap, nonad
