Sorting seed potatoes

, : Sorting seed potatoes. Mekhanizatsiya i Elektrifikatsiya Sotsialisticheskogo Sel' skogo Khozyaistva (4): 48-49

Since spool type potato sorters tend to cause damage to the tubers, trials were conducted with a converging endless belt type of machine with a range of grading clearances from 10 to 61 mm, a length of the stepped arrays of belts from 200 to 1200 mm, belts speeds of 0.083 - 0.72 m/s and inclinations of 0 - 10 deg. Performance was evaluated from the grading precision and the distance travelled by the trash before it was separated.

Both p53 and Mdmx are ubiquitinated and degraded by the same E3 ligase Mdm2; interestingly, however, while p53 is rapidly degraded by Mdm2, Mdmx is a stable protein in most cancer cells. Thus, the mechanism by which Mdmx is degraded by Mdm2 needs...
