China's price-support policy has led to a sharp expansion in grain output: it now holds about 40% of global inventory.
The gradual introduction of mechanical combines and, in America, the expansion of grain production across the Great Plains after the Civil War were quickly making German wheat, oats, barley, and rye uncompetitive both at home and in the London commodity markets.
It is normally considered that the thermal expansion of grain boundary was enhanced in comparison with that of crystallite due to their excess volume for bulk NC materials [15, 23].
Issues such as thermal expansion, stress relaxation, grain growth, and oxidation can be critical in order to have a working bottom electrode.
The salt expansion of coarse grain soil with and without salt concentration layer is designed to compare their difference in laboratory.
Two-stage length changes of UFG Al were observed which are explained by counteracting effects of expansion due to grain boundary segregation of Ga and contraction due to precipitation and recrystallization.
The DEM specimen is created using the radius expansion method with grain size distribution similar to that of the backfill material.
Even so, expansion in commodity grain- and oil-based biofuels is nearing its economic, ecological, and political ceiling – regardless of which side of the debate the food vs. fuel evidence settles.
Thus, drought can have large effects on common bean growth either during early establishment, vegetative expansion, flowering, or grain filling (Rao 2001).
The expansin gene TC418521, a potential target of miR1137, was highly abundant during early grain expansion but later repressed, implying that levels of expansin are a possible factor in determining grain size [ 45].
