Life history of the Obscure Root Weevil, Sciopithes obscurus (Horn), on rhododendron

Creator:: Bell, Harry Thomas
Abstract:: The life history of the Obscure Root Weevil, Sciopithes obscurus (Horn), on Rhododendron was studied at four sites in the Willamette Valley. This research was conducted in an effort to provide information necessary to develop adequate methods to control this Curculionid pest on Rhododendron in the Willamette Valley. Five larval...

Design and evaluation of a foundation model testing device

Creator:: Kelly, Patrick Bryan
Abstract:: Model testing has proven to be an effective tool in the study of soil-structure systems. While primarily used in research work, this method of evaluation is also applicable to the solution of many types of complex design problems. Because of its workability and relatively simple characteristics, sand is the most...

Consolidation characteristics of sand-clay mixtures

Creator:: Anderson, Donald G. (Donald Gordon)
Abstract:: Combinations of cohesive and cohesionless soils are often encountered when evaluating the engineering properties of soils. The stress-volume characteristics of the mixed soil are found to vary according to the proportion of each component. If the cohesive soil composes more than a certain fraction of the material, the magnitude of...

Test method to determine the degree of asphalt stripping from aggregates

Creator:: Boudreau, Richard L.
Abstract:: Moisture damage has long been recognized as one of the most critical factors influencing the performance of asphalt concrete (AC) pavements. This moistureinduced damage occurs from either the physical separation of the asphalt film from the aggregate or the softening of the asphalt binder within the AC mixture in the...

Needs Assessment for Future US Pear Rootstock Research Directions Based on the Current State of Pear Production and Rootstock Research

Creator:: Elkins, Rachel B., Bell, Richard, and Einhorn, Todd
Abstract:: The area devoted to pear production in the United States (U.S.) is declining due to lack of precocity and high cost of production. The U.S. pear industry currently lacks "modern" orchard systems characterized by compact trees that produce early, high yields of large, high quality fruit. Tall, shaded canopies are...

A preliminary investigation into the use of the tarif system and three tree selection methods for obtaining Douglas-fir stand and stock tables from large-scale aerial photography

Creator:: McCadden, Richard Jay
Abstract:: As a preliminary step toward the establishment of a 70 mm. aerial photo timber inventory system capable of generating accurate stand tables, stock tables, and gross volume estimates, this project focuses on the development of a system which (1) eliminates the need to measure tree height on the photos through...
