in order to study the realationship between genetic diversity and different characteristics associated with grain yield in barley, 28 genotypes of barley cultivars contain seven cultivars and 21 hybrids were evaluated in randomized complete block (rcb) design with three replications. cultivars were valfajr, makuei, kavir, rayhan, gorgan, nusrat and nimroz. this study was carried out in research...

Primary requirements of wireless multimedia handheld computers are high-performance, flexibility, energy-efficiency and low costs. A compromise for these contradicting requirements can be found in a heterogeneous SoC. Besides conventional architectures such a SoC contains domain specific coarse grain reconfigurable processors and fine-grain reconfigurable entities. The MONTIUM is a prototype of...

Feeding grain whole to cattle generally results in a lower digestibility than that obtained with processed grain. If this problem could be overcome, feeding with whole grain would reduce processing costs, and the slower rate of starch digestion in the rumen could improve fibre digestion with potential beneficial effects on intake and animal production. Two strategies are available to increase t...

quantifying morphological characteristics of body shape in fishes can help their correct identification as well as understanding of evolutionary history of their different populations. hence, this study was aimed to compare the morphological characteristics of different population of tuini fish (capoeta damascina) in inland-water of iran using geometic morphometrics method (gm). in total 373 sp...

Superplastic structural ceramics (Y-TZP, A1203, Si3N4, and their composites) that can withstand biaxial stretching to large strains have been developed recently. Microstructural design of these ceramics first requires an ultrafine grain size that is stable against coarsening during sintering and deformation. A low sintering temperature is a necessary, but not a sufficient, condition for achievi...

Hydraulic conductivity is commonly estimated from grain size characteristics of unconsolidated sediments. We present an extensive set of air-permeability and grain size measurements from a heterogeneous aquifer. These data are unique in that the hydraulic conductivity measurements are made on undisturbed in-situ sediment and, like the grain size measurements, have a small sample volume size (<1...

Unlike maize and wheat, where artificial selection is associated with an almost uniform increase in seed or grain size, domesticated rice exhibits dramatic phenotypic diversity for grain size and shape. Here we clone and characterize GS3, an evolutionarily important gene controlling grain size in rice. We show that GS3 is highly expressed in young panicles in both short- and long-grained variet...

abstract in order to investigate the effects of different irrigation regimes on yield and yield components of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad. six irrigation regimes including i1= full irrigation, i2= irrigation at branching, i3= irrigation at flowering, i4= irrigation at pod formation, i5= irrigation at seed filling stage, and i6=...
