this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

Bulk Ag2S is a plastic inorganic semiconductor at room temperature. It exhibits compressive strain greater than 50%, which highly different from brittle conventional counterparts, such as silicon. Here, we present the experimental investigation of deformation behavior in using situ neutron diffraction during and elevated temperatures. At temperature, lattice partitioning among hkl-orientated gr...

it is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (dcr). however, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. in general, multi-directional defor...

We have investigated the partitioning of solutes at crystal defects in intergranular Cr-rich M2B borides after creep 850°C/185MPa and annealing 850°C for approximately 3000 h a polycrystalline nickel-based superalloy. Borides were found to coarsen both cases, with being thickest (800–1100 nm), compared annealed absence an external applied load (400–600 nm). Transmission electron microscopy reve...

this study was carried out to determine some mechanical properties of barley seed including deformation, rapture force, rapture energy and toughness as a function of moisture content (10.5%, 12.5%, 14.5% , 16.5%, db), loading rate (5, 15, 25, 35 mm.min-1) and grain size (small, medium, large). tests were performed at 7 replications by the means of a factorial base plot experiment. the results s...

deformation length is one of the most important parameters in cold roll-forming process, which plays a fundamental role in determining the inter-distance between the stations and rate of deformation. deformation length was first introduced by bhattacharyya. he also obtained a closed-form relation for this length in roll-forming of symmetric channel section. in this paper, deformation length in ...

To study the viscosity of bridgmanite and ferropericlase aggregate, uniaxial compression deformation experiments on pre-synthesized post-spinel phase two-layered samples were conducted under top lower mantle pressure 1773 K utilizing DT-Cup apparatus. Up to strain 0.25 ± 0.05, observed comparable suggests dominates bulk without localization in periclase. The microstructures deformed show eviden...

background: sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. this study was carried out for assessing co, ni, and zn in sediment samples of mighan wetland using geo-accumulation index in 2013. methods:the sediment samples were taken from 11 stations. the samples were subjected to bulk digest...
