The high-grade steel being used in Iter is good enough to deal with the plasma and the radiation from the relatively small amounts of power (500MW) that will be produced there for a few minutes at a time, but commercial power plants will need much hardier materials in order to deal with the result of a plasma producing three or four times that much power, day in, day out.
By a "world of shadows," Eddington meant that material reality is no longer the hardy stuff we once thought it to be.
Seal cracks with caulk or another hardy, impenetrable material.
These are hardy, sometimes rough materials, and many of them feel anything but luxurious.
It may not have the glamour of silk or the soft touch of cashmere, but the material uniting designers at the spring/summer 2015 men's fashion catwalk shows is made of hardier stuff.
The scientists' surprising finding, which was published Wednesday in the journal PLOS One, suggests that genetic material is hardier than previously thought and may have the potential to stow away on robotic landers bound for other worlds, or within meteors, the report said.
Natural Resource Conservation Service (NRCS) Plant Material Centers throughout the Western USA developed hardy and prolific varieties of commonly seeded grasses, especially cool-season perennial grasses such as wheatgrasses.
To increase the effect of our analyses we filtered the data for minor allele frequency, Hardy-Weinberg equilibrium deviation, and failure rate (see section Materials and methods).
STRUCTURE is widely used for identifying population subdivision, but it was developed for natural outcrossing populations and has the assumption of Hardy-Weinberg equilibrium which is violated by most breeding materials, including inbred lines.
Subtropical foliage makes up most of the plant material, and alongside tough Trachycarpus fortunei are less hardy palms, among them the date palm Phoenix canariensis and the blue-leaved Butia capitata.
