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...

The Expanding Ring Search is a useful technique for reducing the overhead of the broadcast storm problem when searching in multi-hop wireless network for Adaptive Trajectory Service. The algorithm searches successively larger areas to find the needed vehicle location information, trajectory service, and wireless network traffic condition. We propose expanding ring search with multi-hop cooperat...

Plants use sunlight for photosynthesis and, as a consequence, are exposed to the ultraviolet (UV) radiation that is present in sunlight. UV radiation is generally divided into three classes: UV-C, UV-6, and UV-A. The UV-C region of the UV spectrum includes wavelengths below 280 nm; these highly energetic wavelengths are effectively absorbed by ozone in the stratosphere and, thus, are not presen...

to evaluate the flour quality 10 flour plants were selected in iran, tehran province. two kinds of flour were sampled from each plant (flour with 87% extraction named straight-run- flour as well as patent flour). samples were analyzed for their moisture content, ash, maximum viscosity of dough, particle size, falling number and the amount of damaged starch, which was determined through maltose ...
