In this thesis we investigate the extension of certain theorems
of additive number theory to three algebraic systems. A generalization
of a theorem by Cauchy and Davenport on the cardinality of the
sum of two sets of residue classes is given. We obtain and compare
estimates for the order of...
The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...
The inheritance of ten characteristics of sweet corn was studied
by quantitative genetic analysis. Characters studied were tassel
date, silk date, plant height, ear height, shank length, husk extension,
tip blanking, number of kernel rows, ear length, and weight of the
first ear.
Diallel crosses were made between seven inbred...
To examine the influence of forest management on wildlife immunity, the innate immune system of wild deer mice (Peromyscus maniculatus) inhabiting forest plots of different management intensities in the Oregon coast range was measured by bactericidal assay. Bactericidal activity was compared across three management levels, including 40-50 year old forest...

In her 2016 article “Beyond Rights as Recognition, Black Twitter and Posthuman Coalitional Possibilities,” Pritha Prasad argues that the hashtag, one of the decade’s most omnipresent features of digital communication, functions as “a performative composing medium that not only demands relationality” and “call[s] for the recognition of both the Black...
A comparative study was made of Pinus ponderosa Laws, and
Arceuthobium campylopodum Engelm. f . campylopodum to determine
(1) whether or not the parasite or parasitized tissues accumulate
abnormal concentrations of minerals, (2) whether or not there
was evidence of a blockage of mineral translocation in the phloem
because of...
For data following a balanced mixed Anova model, the standard Anova method typically leads to exact F tests of the usual hypotheses about fixed effects. However, for most unbalanced designs with most hypotheses, the Anova method does not produce exact tests, and approximate methods are needed. One approach to approximate...
The purpose of the present study has been the specification
and measurement of the characteristics of the intraseasonal demand
for fresh Bartlett pears. In particular, the study has focused
attention on a particular producing area, the Rogue River Valley
of Oregon.
The intraseasonal analysis for fresh Bartlett pears was
performed...
Treated wood commodities disposed of in landfills contain chemicals that can migrate into the environment. Wood treatments such as ammoniacal copper zinc arsenate (ACZA) contain heavy metals which prevent the biological degradation of wood. These metals can migrate out of treated wood into soil or groundwater, posing environmental hazards. This...
