From July 16 to 20, 2007, international partners in a trans- Atlantic workshop series on coastal mapping and informatics, held a workshop on the campus of Oregon State University entitled “Coastal Atlas Interoperability.” The workshop engaged 27 participants from 6 countries, representing 17 organizations and multiple areas of scientific and...
Soybeans were grown in hydroponic solutions and in perlite to
devise procedures to measure plant mineral accumulation and
solution depletion over time. Electron emission spectrometry and
micro-Kjeldahl-autoanalyzer analytic techniques were used to
monitor mineral content of individual plants and their corresponding
solutions. An automated computer assisted system of converting
raw...
This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...
Five nutritional aspects of 'Valencia' orange production in Agadir, Morocco
during 1989-1991 were evaluated: 1) the effect of N and K on yield and fruit
quality, 2) leaf sampling time and diagnostic approaches to optimize mineral
nutrition, 3) mass and mineral partitioning within individual trees, 4) K-Rb
relationships, and 5)...
Most conventional approaches to rating turf color for different turf varieties grown
under similar conditions or for the same variety grown under different cultural conditions
employ a visual subjective rating. By digitizing remotely sensed images acquired by use
of a helium filled blimp and a Canon EOS camera, we were...
The dynamics of N was studied in field grown Comice/Provence
quince BA29 pears in Medford, Oregon. Total tree biomass, N content,
and ¹⁵N evaluations suggest that young pears require little N (48 kg
N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was
remobilized into new...
Malheur County is located in the southeast corner of Oregon and consists of about 64 million acres of which 260,000 acres is irrigated. Groundwater contamination has been found in a 115,000 acre area in Northeastern Malheur County. The main source of the groundwater contamination is agricultural practices. The overall objective...
A portion of this study was initiated to provide the
basis for implementing a chill unit accumulation procedure
in Yemen. Most continuous or daily minimum, maximum
temperature models severely underestimated chilling units,
and slight modifications offered little improvement for the
complex models. Only the Crossa Raynaud formula approximated
generally accepted...
The feasibility of using a post harvest sampling time for
fruit testing in Anjou pears was evaluated. The goal was to
determine if a simple and rapid analysis of fruit tissues could be
useful in identifying potentially weak fruit that could be
marketed before the onset of the storage disorder...
Three thinning levels were applied to
twenty-five-year-old D'Anjou pear trees in a completely
randomized design with five single-tree replicates on June 2,
1985. Samples of wood, shoot leaves, shoot twigs, spur
leaves, spur twigs and fruits were taken every month during
the season of growth for mineral analysis. Sampling an...
This study evaluates Beufil's Diagnosis and
Recommendation Integrated System (DRIS) on hazelnuts.
Although sufficiency ranges are currently the main
approach for fertilizer recommendations in Oregon, DRIS
enhanced nutritional interpretations, and might alter
recommendations. Reference values (DRIS norms) were
developed using 15 years of published and unpublished
field data. DRIS indices...
Two experiments were conducted to evaluate the effects of forage quality and supplemental undegradable intake protein (UIP) level on intake, digestibility, and performance of beef cattle. In Exp. 1, five ruminally cannulated steers (BW = 456 ± 6 kg) were used in a 6 x 5 incomplete Latin square with...
Proxy Pipe is designed to be a bus in the transport layer of the communication between the two different processes. Its major function is to transfer bytes. When the client process tries to send a command to the server process, it will talk to a proxy as if it were...
People will spend a large amount of their lifetime indoors where the air is filled with both indoor and outdoor allergens. Exposure to allergens can have a range of effects on the health of building occupants. Textiles make up a vast majority of the surfaces, such as draperies, sofas, pillows,...
The structuring of canopy arthropod communities was reviewed and investigated in relation to tree species diversity and its component factors, interspersion of different species and density of each tree species. Fifteen treatments of Douglas-fir (Pseudotsuga menziesii) and red alder (Alnus rubra) (various densities and proportions of each) were randomly assigned...
The inherent and apparent optical properties of different ocean regimes are the basis for all optical remote sensing of the ocean. Ecological information derived from remote sensors therefore relies on having a detailed understanding of how particulate backscattering and absorption contribute to the bulk optical signal. The absorption
characteristics of...
