Description and life history of Cardicola alseae sp.n. (Trematoda : Sanguinicolidae)

Creator:: Meade, Thomas Gerald
Abstract:: Cardicola alseae is a blood dwelling trematode found in the fishes Salmo clarki henshawi and Salmo gairdneri gairdneri. Eggs which were ovoid in shape and non-operculate left the adult and passed to the gill capillaries of the secondary lamellae. The miracidium was ovoid, 0.070 mm. long by 0.052 mm. wide,...

Mass-flow control system utilizing flow-feedback for gas chromatography

Creator:: Dodo, Gerald Haruo
Abstract:: A unique mass-flow control system for the carrier gas in gas chromatography is described and evaluated. Carrier gas flow is controlled by a flow sensor, feedback electronics, a flow-control valve and a microcomputer. The flow-rate is monitored by a mass-flow meter by this system and the flow is adjusted in...

Statistical quality control applied to asphalt concrete

Creator:: Coghlan, Gerald Thomas
Abstract:: The purpose of this study was to investigate an application of statistical concepts to quality control of highway construction. The application was presented qualitatively and demonstrated quantitatively by an investigation of asphalt content in asphalt concrete. For the example, an Oregon State Highway Project was sampled and tested. The average...

A comparative karyotype analysis of pseudotsuga menziesii [Mirb.] Franco and Pseudotsuga wilsoniana [Hayata]

Creator:: Thomas, Gerald Evan
Abstract:: Karyotype analyses have been madeon only two on the six recognized species in the genus Pseudotsuga, Douglas-fir (P. menziesii) and bigcone Douglas-fir (P. macrocarpa). In this study, a comparison was made between the karyotypes of Douglas-fir and Formosan Douglas-fir (P. wiloniana). The basic chromosome number of the Formosan Douglas-fir was...

The role of soil-water depletion and plant-moisture stress in soil classification and cambial activity of Douglas-fir

Creator:: Thomas, Byron R.
Abstract:: Relationships between soil-water stress and plant-moisture stress were studied with respect to soil classification and cambial activity in Douglas-fir. The study sites were forested with Douglas-fir and located in McDonald Forest and near Marys Peak in the Oregon Coast Range. Soil-water depletion was followed by the use of gypsum blocks...

Nitrogen recovery from simulated sand-filter effluent by grass

Creator:: Hall, Thomas David
Abstract:: The effluent from on-site sewage disposal systems has been found to be a source of nitrates (NO ₃⁻ ) in groundwater. Vegetation has the ability to remove some of the nitrogen (N) from sewage effluent as the solution moves through the soil around a disposal trench, before it reaches groundwater....

Population dynamics of coastal cutthroat trout in an experimental stream

Creator:: Nickelson, Thomas E.
Abstract:: Population dynamics of coastal cutthroat trout were studied in a controlled-flow section of Berry Creek, Oregon, from August 1972 to August 1973. All trout except the underyearlings were tagged to allow movement, survival and weight change of individual trout to be monitored. Fifty-eight percent of the tagged trout which were...

The computer, the computer user group, and the civil engineer

Creator:: Cunningham, Gerald Robert
Abstract:: An attempt to determine the relationship between the computer, the computer program exchange organization and today's practicing civil engineer has just been completed. A questionnaire was used to obtain information and opinions from 850 selected practicing civil engineers. Based on those questionnaires reaching their addresses, a return rate of 81.7...
