Recreation experience management zones for whitewater boating in the Lower Deschutes River Canyon

Creator:: Lowney, David W.
Abstract:: Rapid increases in the recreational use of the Lower Deschutes River Canyon threaten the quality and diversity of downriver recreational experiences. The concept of recreation experience management is discussed and recreation experience management zones for whitewater boating are delineated and described.

Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...

Effect of late foliar applications of urea on protein, hardness, and yield of winter wheat cultivars (Triticum aestivum L.)

Creator:: Altman, David W.
Abstract:: The response of cultivars of winter wheat to foliar applications of urea was examined for grain protein content, yield, and kernel hardness. The objectives of this study were to measure the effect of urea on these three traits in diverse environments and to explain how potential responses could occur by...

Castle Rocks : a late miocene eruptive center at the north end of Green Ridge, Jefferson County, Oregon

Creator:: Wendland, David W.
Abstract:: Castle Rocks is 12 miles east of Mt. Jefferson, in the central Cascades of Oregon. The area contains volcanic rocks ranging from mid-Miocene to Holocene in age. These rocks record alternating periods of tholeiitic and calc-alkaline volcanism. The oldest rocks in the area range from basaltic andesite lava flows to...

Current-feedthrough cancellation technique for current-mode T/H circuits

Creator:: Young, David Y. W.
Abstract:: In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

Breeding habitat of harlequin ducks in Prince William Sound, Alaska

Creator:: Crowley, David W.
Abstract:: Breeding habitat of Harlequin ducks (Histrionicus histrionicus) was studied in eastern Prince William Sound, Alaska, during 1991 - 1993. Streams in Prince William Sound were surveyed for Harlequin ducks and monitored with mist nets. Physical characteristics of 24 Harlequin breeding streams were compared to those of 24 streams not used...

Digital clocks based upon dual side band suppressed carrier modulation

Creator:: Arnett, David W.
Abstract:: A method and apparatus are presented for generating suppressed carrier digital clock signals. These clock signals have the advantage of being broad band in nature and thus exhibiting lower power spectral density. Structures or systems utilizing such clock signals would be less likely to create electromagnetic noise of sufficient intensity...

Subsurface structural evolution along the northern Whittier fault zone of the eastern Los Angeles basin, Southern California

Creator:: Herzog, David W.
Abstract:: The Whittier fault forms the central part of a fault system extending from the East Montebello fault at Whittier Narrows to the Elsinore fault, which is traced as far as the Mexican border. The Whittier fault forms a restraining bend in this fault system, resulting in uplift of the Puente...
