Techniques for measuring changes in the packing state and cone resistance of soil after the passage of wheels and tracks


, : Techniques for measuring changes in the packing state and cone resistance of soil after the passage of wheels and tracks. Journal of Soil Science 24(3): 311-323

A gamma-ray transmission system was used with automatically controlled scanning in a 2 X 2 cm grid in soil sections of 1.08 m length by 0.3 m depth, employing a scintillator/photomultiplier detector assembly with stabilized pulse-height analysis and magnetic tape recording.

A novel chiral open-framework structural hexanary chalcogenoborate, (K(3)I)[SmB(12)(GaS(4))(3)] (1), was obtained by a facile approach using boron as the reducing reagent; it shows weak SHG-activity and is transparent in the mid-IR region.
