Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...

Phage 34 transduces some R factors to Proteus mirabilis strain 13. These transductants can transmit the R factor by conjugation. Transduction frequencies vary from I x I ~-~/plaque-forming unit (p.f.u.) adsorbed (higher than .chromosomal marker transduction) to 5 x Io-8/p.f.u. adsorbed. Transduced drug resistance markers of other R factors were detected only in the presence of resident$factors ...

Objective: The Self-Compassion Scale (SCS) which originally developed by Neff (2003a) is based on the assumption that the self-compassion comprised by self-kindness/self-judgment, common humanity/perceived isolation, and mindfulness/over-identification. This research was aimed to confirm the six-factor structure of SCS. Methods: 265 university students entered the research to assess the psyc...

RESTRICTION in Escherichia coli limits the acceptance of genetic elements such as bacteriophage, sex-factor, and donated bacterial chromosome. These extrinsic genetic elements carry a specificity determined by their last host. When the specificity differs from that of the new potential host, the genetic element is restricted by the new host cell. Restriction is manifest by low efficiency of pla...
