Counting grain mounts; number percentage vs. number frequency

Journal of Sedimentary Research, 1969
ABSTRACT Quantitative mineralogical analysis of grain mounts results in either a number percentage or a number frequency. The number percentage is obtained when all the grains on the slide or all the grains in representative portions of the slide are counted. The number percentage is solely a function of the numerical abundance of the mineral grains in

The number of contiguous neighbors of grains in polycrystalline materials

Journal of Applied Physics, 1993
The stochastic field approach to grain growth in polycrystalline materials permits to combine the stochastic element of the process with physical mechanisms causing grain growth without violating volume conservation, connectivity, and continuity. However, a stochastic field analysis requires knowledge of the number of nearest neighbors of the grains ...

Reynolds number in restricted movement of mineral grains

Soviet Mining Science, 1974
The authors determine the conditions of similarity for restricted motion of grains in a stream at constant velocity which are common with the conditions for free motion governed by the similarity rule of Reynolds. In the Reynolds number for restricted conditions, the characteristic parameter should be a linear quantity characterizing the thickness of ...

Gene Network of Grain Size and Number in Rice

2018
Grain size and number are two key components determining rice yield. As both phenotypes are characterized by quantitative traits, grain size and number are predominantly and tightly controlled by genetic factors. Several quantitative trait loci (QTLs) responsible for grain size and number have been molecularly identified and characterized.
