genotypes of iranian zel sheep for calpastatin(cast) locus were determined by polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) and polymerase chain reaction-single strand conformation polymorphism (pcr-sscp) methods and for calpain(capn) locus by pcr-sscp. blood samples were collected from 200 purebred zel sheep of zel breeding station located in golestan province i...

in this research, the microstructural of low molecular weight 1,2-polybutadiene (1,2-pbd) was conducted by 1h and 13c nuclear magnetic resonance spectroscopy (nmr) to determine the isomeric contents of 1,4-cis, 1,4-trans and 1,2-vinyl in 1,2-pbd polymer structures. number average molecular weight for low molecular weight 1,2-pbd was measured by nmr techniques and the results were compared with ...

The order-order transition temperature (T(OOT)) in blends of poly(styrene-b-isoprene-b-styrene) (S-I-S) triblock copolymer and polyisoprene (PI) homopolymer was investigated by using synchrotron small-angle X-ray scattering (SAXS). Pure triblock copolymer undergoes an order-order transition (OOT) from hexagonally ordered cylinder (HEX) to body centered cubic (BCC) phases. In order to investigat...
