The relationship of exchange acidity and exchangeable aluminum in limed and unlimed profile samples of soil from western Oregon to the yield and chemical composition of alfalfa

Creator:

Janghorbani, Morteza

Abstract:

Acidity distribution within any given soil profile is dependent on mineralogical make-up of the parent material as well as environmental conditions prevalent during the weathering history of the soil. An experiment was designed to study the distribution pattern of exchange acidity, exchangeable aluminum, exchangeable manganese and pH of six acid...

Application of piezoelectric quartz crystal as partition detector : development of a digital transducer

Creator:

Janghorbani, Morteza

Abstract:

AT-cut piezoelectric quartz crystals coated with low vapor pressure materials are evaluated as digital transducers in completely digital detection systems for monitoring gas streams. Mathematical relations describing the detectors are developed and tested. Specific application is made to monitoring gaseous sulfur compounds commonly found in stack effluents of pulp mills....
