A kinetics-based enzyme-linked immunosorbent assay (KELA) for detection of serum IgG antibody against bovine respiratory syncytial virus (BRSV) was developed and optimized. Optimization factors tested included brand of microELISA plate, length of incubation periods at various temperatures, type of conjugate, purified versus precipitated antigen preparations, type of dilution buffer as...
The behavioral repertoire of the sea anemone, Anthopleura
xanthogrammica, was investigated to test for the occurrence of any
immediate response to various regions of the electromagnetic spectrum.
Monochromatic radiations in the visible and ultraviolet spectral
regions were produced by a 150-watt xenon lamp or a ZOO watt mercury
vapor lamp...
I studied the water relations traits, twig conductivity, C'3 isotopic composition,
and wood density of three conifer and five angiosperm species in western Oregon. This
study took place from spring 2002 to fall 2003 on four sites. Species were selected to
represent the diversity of drought tolerance of woody plants...
The primary purpose of this thesis is to determine the economic nature of low incomes on low-income farms in western Oregon. An economic model containing variables that contribute to family income is developed for farm operators in the study area. Regression analysis is used to determine the significant variables contributing...
A comparison was made of the d.c. conductivity of KCI:Pb²⁺
and KCl:PbO single crystals at temperatures greater than 325°C.
The energy of activation was 0.72 ev for all crystals. Lead concentration
was determined by chemical, optical and electrical methods. The
half band width of the UV absorption band at 273...
An experiment was conducted to determine the
suitability of a new variety of yellow pea (Pisum sativum
L., var. Miranda) as a feed ingredient in broiler breeder
diets. Two-hundred twenty-five I S A Vedette dwarf broiler
breeder pullets were fed either a corn-soy (CS) or corn-pea
(CP) diet from day...
Attempts to synthesize diboron tetrafluoride by the reduction of
boron trifluoride with alkali metal solutions in 1, 2-dimethoxyethane
proved to be unsuccessful. No diboron tetrahalide was found when
boron trifluoride, antimony trifluoride, or boron trichloride was
reacted with tetra-(dimethylamino)-diboron; although there appeared
to be some exchange between chloride and amine...
