Growth data compiled in this study were collected by using
pigs farrowed during the fall, 1963 and spring, 1964 farrowing seasons
of the Oregon State University swine herd. Thirty-seven trios
of light-, medium- and heavy-birth-weight suckling pigs were used to
determine the effect of birth weight on subsequent rate of...
Understanding magmatic processes occurring at depth in magmatic systems is fundamental for a more complete understanding of the variations sampled in lavas erupted from these systems on the Earth's surface. This thesis presents the results of detailed trace element analyses of plagioclase and clinopyroxene phenocrysts measured by laser ablation-inductively coupled...
The purpose of this study was to find what effect temperature
and immunization has on the phagocytic activity of fish leukocytes
against certain disease causing bacteria. Also proposed was the
isolation and characterization of a leukocytolytic factor produced by
one of these bacteria, Aeromonas salmonicida.
Investigations revealed that temperature had...
China’s global influence in the realm of science and technology (S&T) has increased dramatically in recent times. China and the United States are now each other’s main partner in scientific collaboration. As a major research university, OSU is one of the institutions with a large stake in this international collaboration....
Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...
