Genetic and morphological characteristics of an architectural mutant in common beans were studied. The mutant had shiny, dark green leaves, overlapping leaflets, short petioles and a reproductive terminal bud even though the line did not carry the fin gene. Branching was nearly absent resulting in a single stem vine. This...
In this thesis the critical parameters involved in the
dislodgement and deformation of microbubbles in laminar
channel flow, are determined and evaluated. Experimentally
the effects of surface tension, viscosity, fluid flow rate,
density, and bubble diameter on bubble dislodgement were
evaluated. A theoretical scale analysis was performed which
provided a...
Differences in primary production and periphyton and macroinvertebrate
biomass between pairs of constrained (valley floor width of less than twice the active
channel width) and unconstrained reaches were investigated in Elk River and four
tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled
from individual cobbles, and rocks were...
Bidirectional reflectance is a fundamental property
used for the analysis of radiative heat transfer. It is a
form of reflectivity in which the spectral and directional
dependencies of both the beam incident on a surface and the
beam reflected from the surface are specified.
A new system has been designed...
Monoclonal antibodies were developed against USDA
challenge strain of infectious laryngotracheitis virus (ILTV).
Indirect immunofluorescence test was used to detect antibodies
in supernatants of hybridomas. Hybridoma cells were developed
by fusing Sp 2/0 myeloma cells with spleen cells obtained from
mice immunized four times with partially purified USDA
challenge strain...
Staphylococcal tenosynovitis and osteomyelitis are world-wide problems of
broilers and broiler breeders caused by staphylococci. Pathogenesis of the disease is
ill defined. Avian heterophils are analogous to mammalian neutrophils but the
granules appear to be different.
The first chemotactic study was done on heterophils from chickens having
natural staphylococcal infection...
