Evaluation and use of a soil mineralizable nitrogen test to determine the fertilizer nitrogen needs of winter wheat grown in western Oregon

Creator:: Baloch, Dost M.
Abstract:: The assessment of optimum nitrogen (N) fertilizer need for winter wheat (Triticum aestivum L.) is important for economic and environmental sustainability. A comprehensive understanding of fertilizer N requirement depends on estimation of the quantity of N needed by the crop versus that supplied by soil. The objectives of this study...

Sulfobromophthalein disposition in rainbow trout (Salmo gairdneri) as influenced by carbon tetrachloride intoxication

Creator:: Gingerich, William H.
Abstract:: Clinical methods to diagnose specific organ dysfunction have not been evaluated in fishes. To determine if an accepted clinical test of mammalian liver function could be applied to fishes, the hepatic disposition of the organic anion sulfobromophthalein (BSP) was studied in rainbow trout (Salmo gairdneri) treated with a model hepatotoxicant....

A comparison of the effect of computer-assisted-instruction and same-age peer-tutoring on math achievement of fourth grade students

Creator:: Pflug, Elizabeth A.
Abstract:: A pretest-posttest design was used to compare the effectiveness of computer-assisted-instruction (CAI) drill and practice with the effectiveness of same-age peer-tutor drill and practice on promoting mastery of multiplication facts. The subjects were students from three, fourth grade classes in the Reedville School District of Aloha, Oregon. Two fourth grade...

A comparison of the effect of oral versus written lesson closure on the achievement of seventh and eighth grade students in social studies

Creator:: Rife, Carol Lee
Abstract:: This was an experimental study which compared two different instructional methods, oral lesson closure versus written lesson closure, on the achievement of 156 junior high school students in social studies. This study was composed of two duplicate experiments. Experiment I was conducted with 71 seventh grade social studies students at...

William Keith Brooks (1848-1908) : a case study in morphology and the development of American biology

Creator:: Benson, Keith Rodney
Abstract:: The major historical studies that have examined American biology have emphasized the development of experimental biology at the end of the nineteenth century. In this characterization, the descriptive branch of biology has often been treated as less than important and, in several cases, as a hindrance in the application of...

Motivational orientations as perceived deterrents to participation among low-literate adults seeking literacy referral services

Creator:: Stanley, Sandra Tierney
Abstract:: This investigation identified perceptions of deterrents to participation in adult literacy programs from among a low- literate non-participating adult population residing in the greater Portland, Oregon metropolitan area. While previous investigators have identified deterrents to participation among other subgroups of the population, such investigations have focused on those currently, or...

Genetic diversity in coastal cutthroat trout and Dolly Varden in Prince William Sound, Alaska

Creator:: Griswold, Kitty E.
Abstract:: Genetic diversity of two salmonid species, Dolly Varden (Salvelinus malma) and coastal cutthroat trout (Oncorhynchus clarki clarki) in Prince William Sound, Alaska were examined at multiple spatial scales with three molecular markers. Pleistocene glaciers covered what is now Prince William Sound 8,000- 12,000 years ago and both species colonized the...

A Computational Method for Building Spherical Pictures and Theoretic Results from Explicit Constructions

Creator:: Merzenich, Matthias C.
Abstract:: Let H be a cyclically-presented group on n generators with a single defining relator. Attempts have been made to classify such groups by their order, their status as a 3-manifold group, and the asphericity status of their presentations. For groups with a defining relator of length 3 these classifications are...
