in order to study the effects of a superabsorbent polymer on yield and yield components of dry land wheat cultivars, a field experiment was carried out in factorial arrangement using randomized complete block design with four replications on research field in khomein city, during 2010-2011 cropping season. the experimental factors included three dry land cultivars called azar2, sardari, rasad a...

Moire interferometry is employed to study toughening in medium to large grain size nominally pure alumina. The fracture scale length, which is characterized by the grain size of the alumina, is systematically varied from 35 to 102 p,m. R curves are derived from bulk mode I compliance calculations for the differing grain sizes and from the near tip moire fringes. The level of material toughening...

due to cereal are affected by drought stress in their lifetime. in order to study gene action of bread wheat under drought stress condition, a generation mean analysis was performed using f1, f2 and f3 generations derived from roushan and kavir. generation mean analysis was performed based on joint scaling test. genetic parameters including additive effect (d), dominance effect (h), additive×ad...

We have identified a new defect at the intersection between grain boundaries and surfaces in Au using atomic resolution transmission electron microscopy. At the junction line of 90 degrees <110> tilt grain boundaries of (110)-(001) orientation with the free surface, a small segment of the grain boundary, about 1 nm in length, dissociates into a triangular region with a chevronlike stacking diso...

in order to study of variation and relationships between morphological traits with yield and its components in three grain sorghum cultivars (kimia, sepideh and payam) and nine promising lines (mgs1-mgs9) received from seed and plant improvement institute, an experiment was conducted as randomized complete block design with four replications in birjand agricultural research station, in two grow...

In West Bengal, it is most promising to tender early maturing high yielding varieties of rice since they can fulfil their life cycle successfully within short period of persisting cool temperature. The objective of this present investigation was to identify these high yielding early maturing genotypes of rice having quality characters and higher performance in grain yield. A study was conducted...

The thermal conductivity reduction due to grain boundary scattering is widely interpreted using a scattering length assumed equal to the grain size and independent of the phonon frequency (gray). To assess these assumptions and decouple the contributions of porosity and grain size, five samples of undoped nanocrystalline silicon have been measured with average grain sizes ranging from 550 to 64...
