In order to understand the atmospheric branch of the earth's
hydrologic cycle on the global scale, an atmospheric moisture balance
is diagnostically analyzed from the January and July data of the OSU
atmospheric general circulation model, which has been integrated for
thirty-nine months of simulation with seasonally-varying sea-surface
temperature and...
The behavior of different parameterizations of mixed layer physics when used in an oceanic general circulation model (OGCM) having coarse resolution of the upper ocean is examined. The method of parameterization is expected to have an important effect on the resulting sea surface temperature, and hence affect the model's overall...
Two Oregon reservoirs contaminated by different mercury
sources were compared for mercury distribution in sediment and
bioaccumulation by fish. The average mercury concentration in
the sediment of Cottage Grove reservoir (0.67 ± 0.05 μg/g dry
wt) was higher than for Dorena Reservoir (0.12 ± 0.01 μg/g dry
wt). Sediment mercury...
The evolutionary relationship between Frankia and actinorhizal plants was evaluated
by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL
nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from
nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia
strains. Although the branching order...
The Gd3+ ion has been used to induce quantum splitting in luminescent
materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum
splitting results from a two-step CRET between Gd3+ and Nd3+, first involving a
transition 6G→6I on Gd3+ and an excitation within the 4f3 configuration of Nd3+
followed by...
Recently there has been a large amount of research into basic human movement as a baseline for robotic motion. Robotic grasping is a challenging problem for a number of reasons. One of which is that it is difficult to accurately know the interaction between the hand and the object, especially...
As CMOS processes keep scaling down devices, the maximum operating frequencies of CMOS devices increase, and hence circuits can process very wide band signals. Moreover, the small physical dimensions of transistors allow the placing of many more blocks into a single chip, including highly accurate analog blocks and complicated digital...
The contributions of Korean immigrant-owned fashion companies (KIOFCs) are increasing in the U.S. fashion industry. This study explored more deeply how KIOFCs can obtain competitiveness in the fiercely competitive fashion market. Specifically, this study 1) described the prominent characteristics of KIOFCs in the Los Angeles area, 2) investigated the multidimensional...
Academic achievement of adolescent children is directly associated with their success in adulthood. Little is known, however, regarding how adolescents in immigrant families academically grow over time and what factors influence the trajectories. Drawing on the National Educational Longitudinal Survey 1988 (NELS: 88), this study aimed to: 1) identify the...
