Pasture renovation with herbicide suppression of weeds and no-till seeding of orchardgrass

Creator:: Fitzsimmons, James P.
Abstract:: No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...

Photoperiod and the timing of pupping in the Pacific harbor seal (Phoca vitulina richardsi) with notes on reproduction in northern fur seals and Dall porpoises

Creator:: Temte, Jonathan L.
Abstract:: Birth and pupping season records of Pacific harbor seals (Phoca vitulina richardsi) were used in an analysis of photoperiod effect on the timing of birth in this species. Dates and latitudes of births were converted into photoperiods using a photoperiod equation. Sequential dates from parturition were converted into photoperiods and...

Factors influencing metribuzin use in strip-planted wheat

Creator:: Zeghida, Ali
Abstract:: Equipment for strip-till planting is under development in wheat-fallow rotations in the Columbia Basin of Oregon. This involves the absence of tillage during the fallow season. At planting time, the strip-till planter creates a narrow band into which the wheat seed is placed. The area between the rows is undisturbed...

Industry-scientist cooperative research : application to the West Coast groundfish fishery

Creator:: Harms, John
Abstract:: Declining harvest levels, static agency research budgets, and increasing tension among scientists, managers, and industry members are the legacy of the present research and management institutions in the West Coast groundfish fishery. Cooperative research, the active participation of the commercial fishing industry in scientific research, is receiving increased attention as...

"The Island" Research Natural Area : a vegetation study with time and location comparisons

Creator:: Fox, M. Anne, 1939-
Abstract:: The purpose of this study was to document vegetation on "The Island", a Research Natural Area at the confluence of the Crooked River and the Deschutes River in central Oregon's Juniperus occidentalis Zone and to compare the results with an earlier study reported in 1964 from 1960-'61 data. Present-day comparisons...

Factors influencing enzymatic browning of ripening bananas

Creator:: Weaver, Connie Marie
Abstract:: Activity of polyphenol oxidase, concentration of 3, 4- dihydroxyphenylethylamine (dopamine), and concentration of ascorbic acid in the pulp of bananas as they ripened were measured and relationships between these factors and both the extent of browning and the susceptibility to discoloration of the fruit during a 30-minute holding period were...

Prediction of Initial Mixing for Municipal Ocean Discharges

Creator:: Teeter, Allan M. and Baumgartner, D. J.
Abstract:: The purpose of this report is to present procedures by which applicants and reviewers can calculate initial dilution and describe the zone of initial dilution surrounding the discharge site. These calculations would be required under regulations proposed by the U.S. Environmental Protection Agency on April 25, 1978 (1) implementing section...

A graphic user interface for monophonic music analysis

Creator:: Matos G., Soraya J.
Abstract:: A Graphic User Interface is developed to determine the existence of a particular sequence of piano notes within a monophonic sound waveform. Such waveforms are recorded within the Graphic User Interface and then passed to the monophonic analysis engine. The first phase of analysis segments the PCM sound data to...
