Investigation of synthetic rope end connections and terminations in timber harvesting applications

Creator:: Hartter, Joel N.
Abstract:: Steel wire rope is the accepted standard in logging. It is strong, durable, stiff, and dependable in the logger's arsenal. However, steel wire rope has several disadvantages: its strength to weight ratio is low; it is difficult and time-consuming to splice; and used wire ropes contain jaggers. Ultra-high molecular weight...

Short-term relationship of timber management and Pacific giant salamander populations, and the response of larval stream amphibian to predators under differing sediment levels

Creator:: Leuthold, Niels C.
Abstract:: In the Pacific Northwest, multiple studies have found negative effects of timber harvest on stream amphibians, but the results have been highly variable and region-specific. In this collection of studies, I examined the short term effect of timber harvest using a field study, and used lab work to examine a...

Optimal irrigation management : a framework, model, and application for optimizing irrigation when supplies are limited

Creator:: Hillyer, Charles C.
Abstract:: Many regions in North America are experiencing water shortages, and these conditions are expected to worsen. The next generation of irrigation scheduling applications must therefore be capable of providing operational advice in support of deficit irrigation strategies. However, the theoretical, technical, and practical challenges associated with deficit irrigation scheduling are...

Improving soil water determination in spatially variable field using fiber optic technology and Bayesian decision theory

Creator:: Sayde, Chadi
Abstract:: Achieving and maintaining sustainability in irrigated agriculture production in the era of rapidly increasing stress on our natural resources require, among other essential actions, optimum control and management of the applied water. Thus, a significant upgrade of the currently available soil water monitoring technologies is needed. The primary goal of...

Mycobacterium tuberculosis Selective Adenosine Kinase Nucleoside Polymers for Inhalation Therapy

Creator:: Snow, Erika
Abstract:: Respiratory illnesses caused by both viral and bacterial infection are serious issues for global healthcare providers. With the emergence of new, drug-resistant forms of these diseases, innovative drugs and treatment therapies are needed. M tuberculosis is an infection that affects a large portion of the world’s population each year. Aerosol...

Structural geology of the Mount Polley Cu-Au district, south-central British Columbia

Creator:: Wafforn, Stephanie R.
Abstract:: The Mount Polley copper-gold deposit is one of a series of porphyry copper deposits that occur in a belt of accreted Mesozoic age island arc terranes in the Canadian Cordillera. The deposit comprises three breccia-hosted Cu-Au ore zones that are associated with a series of monzodiorite to monzonite intrusions emplaced...

Petrology and geochemistry of the Emigrant Pass volcanics, Nevada : implications for a magmatic-hydrothermal origin of the Carlin gold deposits

Creator:: Johnson, Curtis L.
Abstract:: The Emigrant Pass volcanics (EPV) are a 38.3 to 36.4 Ma calc-alkaline volcanic center that erupted andesite and dacite, and a late series of felsic dikes along the south flank of the Carlin gold district in north-central Nevada. The EPV includes dacite and rhyolite porphyry dikes indistinguishable from porphyry dikes...

Loggers and logging equipment for wildland firefighting

Creator:: Bielecki, Christopher Scott
Abstract:: The three most expensive wildland fire suppression seasons have occurred since 2000, each exceeding $1 billion. Many problems and issues have been highlighted including the grounding of the federal air tanker fleet, training problems with private contractors, overspending, poor management strategies, negative public pefceptions, and the inability to utilize the...

Aerial forest operations : mineral amendment project

Creator:: Cornell, Jennie L.
Abstract:: A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...

Applications for synthetic rope in logging

Creator:: Leonard, Jared M.
Abstract:: Steel wire rope is used for many logging applications. This material has served the logging industry well in terms of strength, durability, and longevity; Steel wire rope is difficult to use because of properties that make it stiff, heavy; and unyielding. These same properties cause fatigue, exhaustion, and may contribute...
