WebParticle size is a notion introduced for comparing dimensions of solid particles ( flecks ), liquid particles ( droplets ), or gaseous particles ( bubbles ). The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size ).

WebThe patented Terrasaw cuts a neat smooth-sided trench approx. 40-45 mm wide and up to 700 mm deep, depending on the model of trenching bar used. The offset transfer case positions the digging bar centrally, providing excellent ergonomic weight balance and maneuverability. The Terrasaw features a heavy duty trenching chain equipped with ... WebThe topsoil properties soil bulk density (BD), soil cohesion (Coh), soil penetration resistance (PR), soil organic matter content (SOM), mean weight diameter (MWD), and straw decomposition rate (SDR) were measured to explain the seasonal variation in Dc.
WebThe following variables were evaluated: root and shoot dry mass, leaf area, tissue P content and morphological parameters of the root system as total length, surface area, volume and root diameter in R2. At the end of the cycle (R8) the number and mass of grains produced in each plant and the weight of a thousand grains were evaluated.
