The rate at which an initially pure field state goes into mixture is calculated for the single-mode laser under the detailed balance condition. It is shown that the field state similar to the coherent state originally suggested by M. O. Scully and W. E. Lamb, Jr. is selected as the most stable state among squeezed states, and that the speed of whole decoherence process is strongly dependent on ...

The genotypes for calpastatin (CAST) and calpain (CAPN) loci were determined by PCR-RFLP and PCRSSCPmethods. Blood samples were collected from 200 pure-bred Zel sheep from Shirang’s Zel sheep Breeding Station located in south-west of Golestan, Iran. Extraction of genomic DNA was performed based on the modified salting out method. Based on results, two investigated loci were polymorphic an...

George H. Shull, while working as a corn geneticist at the Cold Spring Harbor Laboratory from 1904 to 1915, observed that when two different pure-bred lines of corn were crossbred the resulting progeny exhibited physical traits superior to those of the parents (Glass, 2010). Shull described the offspring of pure-bred crosses as having increased heartiness, size, fruitfulness, speed of developme...

This article reports the first known study on the disposal of puppies in an Afro-Caribbean community. The study reported the fate of 2,427 puppies through 517 interviews with dog caregivers. The study reported that surviving puppies from "pure-bred" females were typically sold (60.1% of surviving puppies) whereas those from mongrel (potcakes) mothers were given away (48.4%). Pure-bred mothers p...
