In this paper, the effect of Equal Channel Angular Pressing (ECAP) process on the structure and mechanical properties of AM30 magnesium alloy was studied. The results showed a considerable effect of ECAP process on creating an ultrafine grain size structure. Scanning Electron Microscope indicated that the grain size dropped from 20.4 µm in the extruded form to 7.2 µm in the first pass and 3.9 µ...

In order to study the relationships between grain yield and its components of Aegilops cylindrica, 48 accessions of this plant species was studied in an experimental augmented design based on randomized complete block designwith4 replications under normal and drought stress conditions in the Agricultural Research Station of Ilam University. The results of correlation analysis between the traits...

Abstract In order to determine the best water production function (CWPF) for predicting grain yield of a soybean crop four models were evaluated. The four functions evaluated were Jensen (1968), Minhas et al (1974) and modified Stewart et al (1977) and modified Bras and Corodova (1981) models. Field experiments were carried out for evaluation of the models. The grain yields simulated by the c...
