Bark chemicals from Shasta red fir as stiffening agents for corrugating medium

Creator:: Oregon Forest Research Center
Abstract:: In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective. Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...

Online preconcentration ICP-MS analysis of rare earth elements in seawater

Creator:: Hathorne, Ed C., Haley, Brian, Stichel, Torben, Grasse, Patricia, Zieringer, Moritz, and Frank, Martin
Abstract:: The rare earth elements (REEs) with their systematically varying properties are powerful tracers of continental inputs, particle scavenging intensity and the oxidation state of seawater. However, their generally low (similar to pmol/kg) concentrations in seawater and fractionation potential during chemical treatment makes them difficult to measure. Here we report a...

Measuring Combine Facilitated Transport of Italian Ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] Seed During Wheat Harvest and Preventing the Distribution of Italian Ryegrass Seed During Harvest by Removal or Destruction of Chaff

Creator:: Roerig, Kyle C.
Abstract:: Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] resistant to multiple herbicide sites of action continues to limit winter wheat production in western Oregon. In addition to impacting wheat production, multiple resistant Italian ryegrass may threaten the market for annual ryegrass seed for cover crops if wheat fields with...

Sources and input mechanisms of hafnium and neodymium in surface waters of the Atlantic sector of the Southern Ocean

Creator:: Stichel, Torben, Frank, Martin, Rickli, Jorg, Hathorne, Ed C., Haley, Brian A., Jeandel, Catherine, and Pradoux, Catherine
Abstract:: Radiogenic isotopes of hafnium (Hf) and neodymium (Nd) are powerful tracers for water mass transport and trace metal cycling in the present and past oceans. However, due to the scarcity of available data the processes governing their distribution are not well understood. Here we present the first combined dissolved Hf...

A study to determine the need for mathematics inservice training for untrained and trained teachers in K-7 rural schools in Manicaland, Zimbabwe

Creator:: Makande, Tendekai Don
Abstract:: The purpose of this study was to determine the need for mathematics inservice training for untrained and trained teachers in K-7 rural schools in Manicaland, Zimbabwe. The auxiliary teachers do not have any professional preparation before entry into the teaching profession. The study sought to determine the mathematics areas needed...

Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

A model for identifying evaluation procedures that have a positive influence on teacher attitude

Creator:: Jones, Sheridan Davis
Abstract:: Teachers and administrators spend many hours of work reviewing the State of Oregon Guidelines and drafting district guidelines in an attempt to make the process of evaluation positive and productive. Most districts agree the primary purpose of evaluation should be for the improvement of instruction. The amended state law, ORS...
