As far as Iran is concerned in arid and semi-arid region and amount of water is limited, improvement of water consuming is very important. One of the ways for storing water is to use superabsorbent polymer. So, this research compared normal and deficit irrigation methods by considering the effects of stockosorb (0.1% and 0.3% by volume) and zeolite (10 weight% and 15 weight%) in two sandy soils...

The thermal conductivity of sunflower seed was determined as a function of moisture content, bulk density and temperature which varies from 0.1 to 30.48% (w.b.) and 437.14 to 352.5 kg/m and 22 to 46°C, 3 respectively. The slope of the linear portion ( T versus ln(t)) method was used to analyze the line source heating data for thermal conductivity determination. Bulk density of sunflower seeds f...

this study was conducted to investigate some moisture-dependent engineering properties of russian olive fruit including fruit dimensions, one thousand seed mass, surface area, sphericity, bulk and true density, angle of sliding and static friction coefficient against different surfaces. the physical properties of russian olive fruit were evaluated as a function of moisture content in the range ...

Soil physical properties have an important role on vegetation growththrough affecting the development of root system. The aim of this study was toinvestigate the trampling effect of livestock grazing on soil physical properties andvegetation cover changes. The experiment was conducted on three range conditionsites (Reference, Key and Critical area) with ten frequencies in HosseinabadeKudistan i...

Characteristics of relaxed density profile and conformation of polymer chains are studied by a Monte Carlo simulation on a discrete lattice in three dimensions using different segmental (kink-jump K, crank-shaft C, reptation R) dynamics. Three distinct density regimes, substrate, bulk, and interface, are identified. With the KC segmental dynamics we find that the substrate coverage grows with a...
