to introduce a new rice cultivar with high grain yield and desirable cooking characteristics for the warm regions of kohgilouyeh-ve-boyrahmad province, 203 lines of rice originated form irri breeding program were evaluated in preliminary and advanced yield trials from 1993 to 2000 in choram agricultural research station. in each year, data were recorded from different agronomical and morpho-phy...

Austenitic stainless steels offer good property combinations for structural component applications in demanding and aggressive environments, including nuclear power plants, where irradiation assisted degradation failures have been reported [1]. Enhanced irradiation tolerance has been reported for materials containing a high density of internal interfaces that act as point defect annihilation or...

The objectives of this study were to determine the nature (aeolian vs. alluvial) and origin of sandy sediments in southwestern Iran (Khuzestan province) were collected in two transects across (NW-SE directions) and perpendicular to the Karkheh River, by using grain sized distribution characteristics, and the mineralogy and micro-texture of quartz grains of forty-five surface samples (0-30cm) at...

the effect of ferrite grain size on the fatigue and tensile properties of dual phase steels with a 0.25 volumefraction of martensite (vm) under different heat treatments was investigated. the heat treatments werehomogenized at 1200 oc along with several subsequent normalizations at 910 oc, resulting in differentmicrostructures and mechanical properties. after heat treatment, the obtained steels...
