An analysis of the slackpulling forces encountered in manual thinning carriages

Creator:: Iff, Ronald H.
Abstract:: The popularity of gravity-return skyline logging systems is now increasing in the Western United States. Simplicity seems to be the basis for their success. While two drum yarders are most commonly used, ·some systems, such as the Wyssen, use only a single drum for yarding. Carriages commonly used with these...

Evaporative heat loss of the upper Middle Fork of the John Day River, northeastern Oregon

Creator:: Benner, David A.
Abstract:: Evaporation was studied along the Middle Fork of the John Day River in northeastern Oregon. Evaporation pans and various meteorological sensors recorded data at nine sites during the summer of 1998; measurements were made at each site over a 3-4 day period. A Dalton-type evaporation model was produced using water...

The economics of western juniper management on ranches located in the John Day Ecological Province of north-central Oregon

Creator:: Aldrich, Gwendolyn A.
Abstract:: Western juniper (Juniperus occidentalis Hook) is a species of juniper native to arid regions of the Pacific Northwest. The western juniper tree has a number of competitive strategies that, in conjunction with an almost complete removal of fire from the ecosystem, have resulted in a significant expansion of its population...

John Turberville Needham (1713-1781) and eighteenth century theories of generation

Creator:: Benson, Keith Rodney
Abstract:: There were two viable theories of generation, preformation and epigenesis, existing in the Seventeenth and Eighteenth Centuries. Due to their irreconcilable nature, they were often at loggerheads during this time interval. The status of these generation theories can be effectively understood in terms of Thomas Kuhn's conception of preparadigm science....

Shallow aquifer characteristics adjacent to the upper Middle Fork John Day River, eastern Oregon

Creator:: Hopson, Richard G.
Abstract:: Subsurface inputs into lotic systems are a primary mechanism for cooling streams with high ambient water temperatures. Objectives of this study include: 1) to determine the effectiveness of Forward Looking Infrared (FLIR) thermal imagery to detect shallow aquifers, 2) to characterize certain physical, spatial, and temporal characteristics of the fluvial,...

Determination of mode of death of John Day Merycoidodontidae (Oreodontidae) by populaton age structure analysis

Creator:: Brown, Melinda Elaine
Abstract:: Volcanic activity during the Tertiary has long been held responsible for the deaths and subsequent fossilization of the vertebrate populations of the John Day region in Oregon. Oreodonts as plains or savannah dwelling ruminant herbivores, were likely to have been subject to potential exposure throughout their lifetime to volcanic debris...

Narrative frames and the works of John Coltrane

Creator:: Duncan, James Bryan
Abstract:: In Culture and Imperialism, Said illustrates that we have no "autonomous cultural forms," but rather "impure" ones that are the products of historically "discrepant experiences." American culture has an interesting relationship with the history of imperialism. The Europeans that settled the U.S. imported slave labor to assist in the growth...

The influence of forest management on headwater stream amphibians at multiple spatial scales

Creator:: Stoddard, Margo A.
Abstract:: To effectively manage for biodiversity at broad, ecosystem scales, the influences of habitat structure at multiple spatial scales on vertebrate species must be understood. There are few studies on the broad-scale habitat requirements of stream amphibians despite their importance in streams in forest ecosystems in the Pacific Northwest (PNW) as...

Comparison of skyline carriages for smallwood harvesting

Creator:: Balcom, John Charles
Abstract:: Three skyline carriage types are analyzed on the basis of their operating characteristics and limitations. Their effect on productivity is expressed as cubic feet per hour yarded to the landing. These carriage types, tested as part of Oregon State University's School of Forestry Smallwood Harvesting Research Program represent those which...
