Synthesis of substituted cyclooctatetraenide dianions ; Cycloheptadienyl complexes of the ḏ- and f̲-transistion elements ; Reactions of cyclohexanone with metal vapors

Creator:: Miller, Jeffrey Templeton
Abstract:: I. Lithium alkyl and aryl monosubstituted cyclooctatetraenide dianions (Li₂ C₈H₇-R; R = methyl, n- butyl, sec- butyl, tert- butyl, phenyl and benzyl) were synthesized by the reaction of the appropriate organolithium reagent with cyclooctatetraene in diethyl ether or tetrahydrofuran. The reaction occurred cleanly and with good yield of lithium monosubstituted...

A three-trophic-level perspective on factors influencing herbivore abundance on collard

Creator:: McIver, James D.
Abstract:: The influence of natural enemies and plant apparency in determining the abundance of the cabbage aphid Brevicoryne brassicae L. and the imported cabbageworm Pieris rapae L. was examined on collards grown in a collard monoculture and in a collard-alfalfa biculture. This design was used to examine the factors affecting collardherbivore...

The root insect-- black-stain root disease association in Douglas-fir : vector relationships and implications for forest management

Creator:: Witcosky, Jeffrey John
Abstract:: Verticicladiella wageneri Kendrick is a vascular wilt pathogen of conifers, causing a black staining of colonized sapwood of roots and lower stem. In Douglas-fir, V. wageneri is intimately associated with insects. Hylastes nigrinus, Pissodes fasciatus, and Steremnuis carinatus are commonly associated with diseased hosts, carry inoculum of V. wageneri in...

Distribution and Ecological roles of arthropods in dead woody materials of ponderosa pine forests, northern California

Creator:: Lemieux, Jeffrey P.
Abstract:: This dissertation describes arthropod responses to and effects on decay processes in ponderosa pine, a dominant forest canopy tree in northern California. We used both descriptive and experimental field techniques to establish how arthropod assemblages depend on and are important to the disintegration of woody structures in forests of this...

Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

Characterization of Fungal Communities in Selected Wood Species by Field Exposure Tests

Creator:: Torres-Andrade, Paola A.
Abstract:: Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...

Knowledge Appropriation and Inventive Productivity

Creator:: Choi, Yohan
Abstract:: Innovation is critical for firm growth and survival. Thus, how much value firms create and capture from their innovative activities has been an interest of scholars. This dissertation explores three important questions on this topic to which extant literature has paid little attention. First, I examine how the external threat...

Effects of biocide treatment on durability and fungal colonization of teak, western redcedar, and redwood

Creator:: Cabrera Orozco, Yohanna
Abstract:: Treating durable, second-growth or plantation-grown material with supplemental chemicals could improve durability while enhancing the uniformity of the products. To test this hypothesis, the effect of two candidate biocide treatments on the durability of teak, redwood, and western redcedar was assessed in a ground proximity field test established in Hawaii....

Evaluating Biochar for the Sustainable Treatment of Heavy Metals in Stormwater: Characteristics, Mechanisms, and Barriers

Creator:: Burch, Sarah
Abstract:: Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...
