Obesity is a complex multifactorial disease resulting from excessive energy intake compared to energy expenditure. The excess energy is mostly stored as fat in enlarged adipocytes, but some lipids may infiltrate other organs such as the liver to form ectopic fat. Adipose tissue and ectopic fat produce and secrete a...
Thermodynamical and dynamical aspects of tropical cloud
clusters are studied using data from the GARP Atlantic Tropical
Experiment (GATE). The data set used in this study is a
three-dimensional gridded set of upper-air analyses constructed by
Ooyama and Chu (Hurricane Research Division, AOML/NOAA and
SSEC-University of Wisconsin) for wind data...
The grain milling industry has undergone substantial change during the past several decades in technical as well as industry structure. This study seeks to determine how industry performance, as reflected in productivity growth, has varied since the 1950's. Productivity growth is represented primarily by its dual rate, the percentage reduction...
A three-year investigation was conducted during 1980-1982 to
evaluate the potential of using herded sheep as a silvicultural tool
to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations
of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest
in May soon after bud break. Averaged over the 2 years of grazing,...
Early studies on the biosynthesis of Sarubicin A, 1, had suggested the
intermediacy of the novel aromatic amino acid 6-hydroxyanthranilic acid,
17. To investigate the biosynthetic steps beyond 17, [¹³C-¹⁵N carboxamide]
6-hydroxyanthranilamide, 27a, was synthesized, and fed to fermentations
of Streptomyces helicus. Incorporation of 27a into 1 provided suggestive
evidence...
Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...
This dissertation consists of four studies of Populus and Eucalyptus biotechnology and genomic science: 1) induction of floral sterility by tapetal expression of the ribonuclease Barnase in Populus; 2) CRISPR Cas9-mediated gene editing targeting LEAFY (LFY) and AGAMOUS (AG) homologs in Populus; 3) induction of floral sterility by CRISPR Cas9...
The relationship between the outgoing long-wave radiation (OLR) field
over the tropical Pacific and wintertime monthly precipitation for the
western U. S. is investigated, using the mid-latitude upper-air circulation
as an intermediary. Principal components (PC's) of the 500mb monthly
averaged height field over the NE Pacific and western North America...
Natural uranium samples were irradiated in-core for 7 seconds using the pneumatic rabbit system within the TRIGA Mark II Reactor at Oregon State University, and then used to generate a gamma-ray spectrum with a high purity germanium (HPGe) detector. The irradiated sample was simulated in Monte Carlo N-Particle (MCNP), a...
