The flow model of single phase flow in the elbow of the vertical tubular leacher was studied by using NaCl solution tracing and microcomputer sampling.
Nasal cannulae are now aailable with a separate tube that can be attached to the sampling probe from a capnograph, thereby allowing for end-tidal CO2 monitoring.
The distribution of the heavy mental elements (HMEs) in eluvial horizons, illuvial horizons and parent material horizons of 26 agricultural soil profiles in Hainan Island was studied.
