A comparison of vegetation suppression and sod-seeding methods using perennial ryegrass in renovation of non-irrigated permament pastures in western Oregon

Creator:: Neumeister, John H.
Abstract:: Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...

A spatial analysis of factors influencing farmland conversion in the Bangkok metropolitan area, Thailand

Creator:: Nathalang, Santita
Abstract:: Agricultural land conversion is a complex process that involves a matrix of decisions and decision-makers. This study examines the nature and relative significance of spatial factors that influence the decisions of farmers who either sell farmland to developers for urban use or retain it for agricultural use. The conceptual model...

Analysis of hydrology and erosion in small, paired watersheds in a juniper-sagebrush area of central Oregon

Creator:: Fisher, Michael, (Michael Patrick), 1966-
Abstract:: Current research indicates that the expansion of western juniper can inhibit soil water retention, storage and prolonged releases from watersheds. This phenomenon is of great importance in eastern Oregon, as western juniper is encroaching into sagebrush/grass communities with a correlated reduction in herbaceous ground cover, resulting in reduced infiltration rates...

Carbonation perception : lexicon development and time-intensity studies

Creator:: Harper, Steven James
Abstract:: A lexicon describing the sensory perception of carbonated water was developed. Temporal aspects and differing ingestion conditions were investigated for Bite and Burn sensation using time-intensity (T-I). Four CO₂ levels (0, 1.7, 2.8, and 4.6 volumes) at 3°C and 10°C were tested. Trained panelists used a 16-pt category scale for...

Development of a methodology for containership load planning

Creator:: Cho, Doug Woon
Abstract:: Ship turnaround time at a marine containerport is an important measure of the port's efficiency and attractiveness. Both the speed and quality of load planning affect the length of turnaround time considerably. Past attempts at computerizing the load planning function have been unsatisfactory and have not reflected the port's objective...

Diet selection by conditioned and unconditioned goats in the sagebrush steppe of Eastern Oregon

Creator:: Richman, Lesley M.
Abstract:: This research examined the diets of angora goats on a sagebrush bunchgrass rangeland. Research objectives were to 1) determine the effects of a positive conditioning method on both mature and immature angora goats; and 2) to quantify plant selection and provide preliminary information as to the potential for using goats...

Distribution center performance assessment

Creator:: Kuo, Chun-Ho, 1969-
Abstract:: The objective of this research is to assess the performance measurement systems currently used in today's distribution centers. A comprehensive investigation of distribution centers' performance measurement system is completed. Three major research phases are included in this study. An overview of distribution centers, including background, components, functions, and material handling...

Effects of host resistance on Mycosphaerella graminicola populations

Creator:: Cowger, Christina
Abstract:: Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...
