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....

The effect of soil acidity and lime placement on root growth and yield of winter wheat and alfalfa

Creator:

Kauffman, Marvin Dean

Abstract:

The application of lime to an acid Nekia soil significantly increased the yield of winter wheat and alfalfa in a field experiment. Crop yields maximized when the lime was partially mixed into the surface four inches of the soil. Thorough mixing of the lime into the surface six inches of...
