Internal damage vs. mechanical properties of microwave-dried wheat grain
drying moisture content damage index stress strain modulus of elasticity
2008/11/24
Grain of Almari winter wheat variety, with two levels of initial moisture content (20 and 25%), was microwave dried for different time periods from 2.5 to 25 min. The resultant internal cracks were d...
Soil mechanical properties of a partly-reloosened (split ploughsystem) and a conventionally-tilled overconsolidated gleyicluvisol derived from glacial till
soil mechanical properties mechanical loosening
2008/11/24
In the Eastern states of Germany, there are many arable soils which have been compacted and overconsolidated as a result of intensive wheeling. These require mechanical loosening in order to improve t...
