Soil samples and soil clods were collected from ten potato fields
in Eastern Oregon. An index of grain size distribution was sought that
would correlate well with compacted soil bulk density. The Hazen
coefficient of uniformity was best related to bulk density. The
limitations of various indices and their relationship...
The response of sweet corn (Zea mays L. var. rugosa cultivar
Jubilee) to 12 populations and four nitrogen rates was studied in a
field experiment. Populations ranged from 43, 904 to 329,800
plants/ha with nitrogen levels ranging from 0 to 224 Kg/ha. A systematic
spacing design was used. Plant height,...
The genus Lichnanthe Burmeister contains eight extant and one
fossil species which are strictly nearctic in distribution. The
subfamily Glaphyrinae, however, is distributed nearly world-wide.
Five species were previously described and three are described as
new herein. All eight extant species are described in detail herein,
synonomies are made current,...
The teliospore of Tilletia caries germinates to produce a promycelium
with a whorl of primary sporidia at its tip. The time between
emergence of the promycelium and the development of primary sporidia
averaged 2.3 h. Fusion between compatible sporidia occurred within
an additional 3.8 h. Primary sporidia appeared to be...
Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...
Feasibility of ohmic heating to overcome gel-weakening in Pacific whiting surimi
was investigated. An ohmic heating apparatus was developed using two rhodium-coated
stainless steel electrodes inside a polyvinyl chloride (PVC) tube, a variable transformer,
and voltage and current transducers. Rapid heating associated with the ohmic process
quickly inactivated endogenous proteinase(s),...
This dissertation studies the development of the design procedures for Steel Slit Panel Frame (SSPF). The (SSPF) system is a seismic force-resisting system (SFRS) with ductile behavior and good energy dissipation up to 5\% to 7\% lateral drift that acting as seismic fuses. The current design guidelines provided valuable information...
