This book examines and evaluates the performance of four standard chisel plough tines: heavy duty, double heart, double heart with wings and duck foot, which were connected with a rigid shank. Experiments were conducted in a soil bin filled with sandy loamy soil, and the experimental factors included varying operation conditions (speed and depth) and their dependency upon a draft force and their components (horizontal and vertical force), specific force (force per unit area), specific ...

Multi-channel analysis of surface wave is a non-destructive seiemic test that measures shear wave velocities of soil. This in situ test is a simpler, faster, efficient and low cost method compared to other previous seismic method that only uses two receivers. The methods is applied in this study used 24 vertical receivers or geophones of 4.5 Hz to record the propagation of surface waves. Furthemore, the seismic data records are transformed to construct ...
