Size of active data set: When the active data set is small, the database can buffer most of it in memory. As your active data set grows, your database needs to load more disk blocks because in-memory buffers are not large enough to contain enough of the active disk blocks. Access pat...
According to this process, the semiconductor quantum dots are prepared by dissolving a material containing a Group II metal (e.g., Zn, Cd, or Hg) and a material containing a Group VI element (e.g., S, Se, or Te), as precursors, in first and second dispersant solutions, respectively,...
