Genome size reduction can trigger rapid …
Conclusions. Punctual reduction in genome size could cause rapid changes in key phenotypic traits that enhance invasive ability. Although the generality of genome size variation leading to phenotypic evolution and the specific genomic mechanisms involved are not known, change in genome size may constitute an important but previously under-appreciated mechanism of rapid evolutionary change that ...

The cost-effectiveness of class size reduction (CSR) was compared with the cost-effectiveness of rapid formative assessment, a promising alternative for raising student achievement.
CPE: Lesson 13. Principle of Size Reduction
The reduction ratio, defined as the relation between average size of feed and average size of product, can be used as an estimate of the performance of a comminution operation. The values for average size of feed and product depend on the method of measurement, but the true arithmetic mean, obtained from screen analyses on samples of the feed and product streams, is commonly used for …

The study of rapid evolution in invasive species has highlighted the fundamental role played by founder events, emergence of genetic novelties through recombination and rapid response to new selective pressures. However, whether rapid adaptation of
Introduction to Size Reduction of Bulk Solids | AIChE
Size reduction or comminution of bulk solids is a very common and important unit operation found across the process industries. Liberation of a key species (ores), improved stone activity or bioavailability (catalysts, pharmaceuticals, and energy storage materials), better product handling characteristics (pulverized coal), etc. are just a few of the reasons for using size reduction technology.
Rapid and Significant Reduction in Size of Pituitary ...
One possible explanation for this rapid response might be related to a rapid growth of this tumor cells, resulting of rapid response of radiation effect. Finally, we have assumed that some patients with nonfunctioning pituitary adenoma treated with radiation may show rapid and significant reduction in size …
