An experimental investigation of transition pool boiling

Creator:: Aoki, Tadao
Abstract:: The heat-transfer phenomena studied in this work were associated with pool boiling from a flat horizontal surface facing upward with the bulk liquid at its saturation temperature. The analysis of boiling sound and the investigation of the transition boiling mechanism constituted the essence of the present study. The distinctively large...

Description and classification of the forests of the upper Illinois River drainage of Southwestern Oregon

Creator:: Atzet, Thomas
Abstract:: The purpose of this study was to develope a plant community classification within the Siskiyou mountains, a small range within the Klamath geological province well known for its geologic and floristic diversity. Forest land managers have expressed the need for identification of basic Land classes that will aid in the...

The influence of increased base saturation and the chloride ion on Fragaria ananassa, Bailey

Creator:: Lyons, Calvin G.
Abstract:: Research was carried out to determine the influence of increasing the percentage base saturation of the soil on the yield of the commercial strawberry. It was found that the effect of increasing the bases in the soils was directly related to the original percentage base saturation. When this original value...

Carbon and energy exchange of semi-arid ecosystems with heterogeneous canopy structure

Creator:: Anthoni, Peter M.
Abstract:: Carbon and energy fluxes were measured with the eddy covariance technique above two semi-arid ecosystems, ponderosa pine and juniper/sagebrush, located in central Oregon. The two ecosystems have low LAI and a very open canopy structure. The energy closure was ~70-80% at both ecosystems, equivalent to an imbalance of 150-250 W...

Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

Some factors controlling the establishment and distribution of Quercus agrifolia Nee and Q. engelmannii Greene in certain southern California oak woodlands

Creator:: Snow, Gerald Eldon
Abstract:: The structure of two oak woodland types in the Santa Rosa region of the Santa Ana Mountains of southern California has been described by Zuill (1967). One type called the grass oak woodland (GOW) is composed mainly of Q. engelmannii on hills and slopes. The other type called the dense...

Factors affecting bird counts and their influence on density estimates

Creator:: McCracken, Marti L.
Abstract:: Variable area surveys are used in large geographic regions to estimate the density of birds distributed over a region. If some birds go undetected, a measure of the effective area surveyed, the amount of area occupied by the birds detected, is needed. The effective area surveyed is determined by observational,...

Ecological relationships between cervid herbivory and understory vegetation in old-growth Sitka spruce-western hemlock forests in western Washington

Creator:: Happe, Patricia Jenkins
Abstract:: The relationships between black-tailed deer (Odocoileus hemionus columbianus) and Roosevelt elk (Cervus elaphus roosevelti) herbivory and understory vegetation in unmanaged forests in Olympic National Park were studied from 1985 - 1989. From 1985 to 1986 I studied the impact of cervid exclusion on shrub, fern, and forb forage quality, tannin...

Pasteurella multocida infection in turkeys : pathogenesis and immunity

Creator:: Tsuji, Masayoshi
Abstract:: Pathogenesis and immunity involved in fowl cholera were studied with the turkey, one of the most susceptible natural hosts. The causative agent, Pasteurella multocida, was analyzed in terms of its virulence and immunogenic factors, using a highly virulent, encapsulated strain P-1059. Protective immunity was induced by lipopolysaccharide (LPS)- protein complex...
