Copper deficiency and Mo-induced Cu deficiency are nutrition
problems of ruminant livestock in the Burns and Klamath Falls area
of Oregon. Chemical analysis of plant and soil samples was used to
survey Cu and Mo levels in forage in these areas. The objectives
were to assess the possibility of animal...
Field-plot experiments and pot culture techniques were used to
investigate reported Cu deficiency in certain Oregon organic soils.
Field experiments were established in 1973 and 1974 on an acid peat
soil and two alkaline muck soils near Klamath Falls, The effect of
rates of from 0 to 45 kg Cu/ha...
Large amounts of energy are wasted when conditioned air in buildings is exhausted to meet ventilation requirements. There are several technologies to recover some of this energy, including the recent development of membrane based energy recovery ventilators (ERVs). ERVs exchange sensible heat and moisture between incoming fresh and outgoing exhaust...
This investigation was designed to determine whether or not the nonverbal behaviors of junior high and secondary school science students could be systematically analyzed. It was further determine what relationship exists between the nonverbal behaviors of students and their attitude. The hypotheses investigated were as follows: H₁: A valid and...
A simplified model of the combined particle convective and
radiative components of heat transfer between large-particle gas-fluidized
beds and immersed surfaces was developed. This analytical
model was based on the single particle formulation of Adams and Welty
[4,9], with the added assumptions of one-dimensional heat conduction
in the particle and...
The transcriptional promoter sequences for the Rhizobium meliloti
nitrogen fixation genes nifA and nifB were cloned to a β-galactosidase gene
fusion plasmid vector and transferred by homologous recombination to a
specialized transducing phage. The promoter fusions were then transduced
to a recombination deficient strain of Escherichia coli as single-copy
lysogens...
Biological, serological, and molecular characteristics
of the P4 pathotype of pea seedborne mosaic potyvirus
(PSbMV) were investigated. The characterization allowed P4
to be differentiated from other pathotypes of the same
virus.
P4 was distinguished from P1 on the basis of host
symptomatology. It induced varied, but often distinctive
symptoms in...
The accomplishments presented in this thesis are the development of three models
for simulation of space charge generation in the phosphor layer of alternating current
thin-film electroluminescent (ACTFEL) devices and the results from simulation
of these models. First, a single sheet charge model is developed and simulated.
The single sheet...
