Wheat hardness by near infrared (NIR) spectroscopy: New insights by Marena Manley The determination of wheat hardness by the evaluation of whole wheat grain would be of considerable value to the UK Milling Industry. Until now, accurate whole wheat grain hardness predictions by NlR spectroscopy have only been reported for North American wheats. By the evaluation of selected samples of UK and Nor...

The effect of the microstructure on the electromigration failure development is analyzed. We investigate the influence of the statistical distribution of copper grain sizes on the electromigration time to failure distribution. Also, the effect of the microstructure on the formation and development of an electromigration-induced void is studied by simulation and the results are compared with exp...

In the short crack regime of the fatigue process, grain boundaries in steels are barriers against crack growth. In this paper, we use: (1) a method involving crack density; and (2) a method of dimensional analysis, to evaluate the effects of grain size and grain-boundary resistance on short crack behaviour and fatigue life. The results show that the fatigue life increases with a decrease in gra...

in order to study the effect of compost and salinity stress on seedling growth and generative traits of wheat (sivand cultivar) a pot experiment was conducted based on complete randomized design arranged in factorial with six replications at the research greenhouse, faculty of agriculture, mashhad branch, islamic azad university, mashhad, iran, during in cropping season 2013-2014. factors were ...

The dynamic nanomechanical characteristics of Cu films with different grain boundaries under nanoindentation and scratch conditions were studied by molecular dynamics (MD) simulations. The type of grain boundary is the main factor in the control of the substrate atoms with respect to the size of dislocations since the existence of the grain boundary itself restricts the movement associated with...

20 hulless barley lines were assessed by grain yield and other agronomic traits in 2006 and 2007 in the research station of the university of tabriz, iran. the experiments in each year were carried out as randomized complete block design with four replications. the genotypes were significantly different for most of the studied traits. this indicated the existence of large genetic variation in t...

in this study, the effect of grain size on nitrogen diffusion into ck45 has been investigated. in order to obtain different grain sizes, samples were annealed and normalized at various temperatures and durations.the grain size was determined with clemex vision software. then, the specimens were exposed to dc plasma nitriding treatment and again analyzed by optical microscope ,scanning electron ...

Grain boundaries have a major effect on the physical properties of two-dimensional layered materials. Therefore, it is important to develop simple, fast and sensitive characterization methods to visualize grain boundaries. Conventional Raman and photoluminescence methods have been used for detecting grain boundaries; however, these techniques are better suited for detection of grain boundaries ...
