A Reexamination of the role of poly-L-glutamic acid on duration of fertility in the chicken

Creator:: Al-Aghbari, Abdulwali M.
Abstract:: Dekalb XL Single Comb White Leghorn pullets were immunized against poly-L-glutamic acid (PGA) complexed with methylated bovine serum albumin (MBSA) at 9 weeks of age. Pullets immunized against MBSA as well as non-immunized pullets served as controls. At 18 weeks of age, pullets were moved from a floor pen into...

Percussive-welded p-n junctions in silicon

Creator:: Tao, David Ming-Shih
Abstract:: This thesis investigates a way to fabricate P-N junctions by percussive welding. The theoretical basis of percussive welding, design considerations of the apparatus used, and the electrical characteristics of the junctions were the main objectives of this investigation. P-type silicon wafers and gold wire doped with arsenic as a N-type...

Analysis of cytochrome P-450 isozymes from rat liver and studies on the mechanism of induction

Creator:: Williams, David Edward
Abstract:: In order to determine the total number of cytochrome P-450 isozymes present in a given species following various treatments, mature male rats (Sprague-Dawley) were injected intraperitoneally with the classic mixed-function oxidase inducers phenobarbital (PB), pregnenolone- 16a-carbonitrile (PCN), 3-methylcholanthrene (3-MC), or the appropriate control vehicle. Hepatic microsomes were solubilized and P-450...

Multiscale habitat electivity and movement patterns by adult spring chinook salmon in seven river basins of northeast Oregon

Creator:: Price, David M.
Abstract:: I examined habitat electivity and movement patterns of adult spring chinook salmon at microhabitat and channel unit spatial scales, and seasonal to annual temporal scales in seven streams in the Grande Ronde, John Day, and Imnaha basins. The objective was to compare habitat use and availability among streams, channel units,...

Detection of dwarf mistletoe in young-growth ponderosa pine from color aerial photography

Creator:: Hann, David W.
Abstract:: The purpose of this study was to determine if infection levels of dwarf mistletoe on ponderosa pine could be detected with color aerial photography. The photography was taken in early September using Kodak Ektachrome Infrared Aero and Ektachrome Aero films at scales of 1/4000, 1/2000, and 1/1000. Ground truth consisted...

Zinc-phosphorus relationships in five plant species

Creator:: Henning, Stanley John
Abstract:: The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses...

The relationships between zinc, iron, and phosphorus in sweet corn

Creator:: Hay, James Ronald
Abstract:: The relationships between zinc, iron, and phosphorus in sweet corn were investigated under field and greenhouse conditions. The soils used in this study (both acid and calcareous) were low in available zinc and phosphorus. The experiments received standard, uniform rates of nitrogen potassium, magnesium, and sulphur. Corn was used as...

Overcoming the obstacles of effective photogrammetric mensuration

Creator:: Farnsworth, Blake Templeton
Abstract:: This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography. This report on the pursuit of...
