Clay mineralogy and related chemical properties of soils formed on Mazama pumice

Creator:

Chichester, Frederick Wesley

Abstract:

A sequence of soil profiles was sampled along a climate-vegetation transect on the dated Mazama pumice fall in central Oregon. The <2 μ size fraction from each sample was characterized with respect to the relative significance of amorphous and crystalline components, and the individual minerals of the latter group were...

Computer-aided majority logic design

Creator:

Schiele, Roy Louis

Abstract:

The emergence of the three-input majority gate as a practical element for logical design has demanded a useful method of design using these elements. In order to facilitate the use of this gate, a digital computer program is presented to implement the design procedure. Utilizing the truth table of a...

The effect of selected insecticides upon biochemical oxidation

Creator:

Norris, Francis Warren, Jr.

Abstract:

A study to determine the effect of certain synthetic organic insecticides on the Biochemical Oxygen Demand (BOD) Test was performed. BOD tests on a standard glucose-glutamic acid substrate were conducted while in the presence of dieldrin, dichlorodiphenyltrichloroethane (DDT), or diazinon. From the BOD data, the following parameters were obtained: 1....
