A microprobe study of metalliferous sediment components

Creator:: Eklund, William Alan
Abstract:: Examination of polished sections of manganese micronodules from metalliferous sediments from the Bauer Deep reveals sequences of ferromanganese deposition which are consistent for micronodules from a single sediment sample and imply a common depositional history for members of such assemblages. The relatively simple 'stratigraphy' of manganese micronodules, as compared to...

Age, chemistry, and tectonic significance of Easter and Sala y Gomez Islands

Creator:: Clark, James Gregory, 1948-
Abstract:: Easter Island and Sala y Gomez are part of the Sala y Gomez Ridge, a broad band of high topography and scattered seamounts extending ESE from the East Pacific Rise. It has been proposed that the Sala y Gomez Ridge results from the movement of the Nazca Plate over a...

Characteristics of Typhlodromus americanus Chant and Yoshida-Shaul (Acari: phytoseiidae) as a biological control agent of Oligonychus ununguis (Jacobi) (Acari: tetranychidae)

Creator:: Horton, Rene N.
Abstract:: The life history, temperature, humidity, and feeding requirements of the phytoseiid predator mite, Typhlodromus americanus Chant and Yoshida-Shaul were tested in the laboratory. Occurance of the mite in the field during different times of the year was investigated as well. Effects of temperature and humidity on egg hatch, the feeding...

The relationship between population and residential property taxes in Oregon

Creator:: Buchanan, Shepard C.
Abstract:: The relationship between population and residential property taxes is not well understood. This study is an attempt to discern the relationship. The basic questions examined are: How does population affect tax bills? What are the short-run and long-run relationships between population and taxes? What reasons lie behind the answers to...

The manganese-enriched sediments of the Blanco Trough : evidence for hydrothermal activity in a fracture zone

Creator:: Selk, Bruce W.
Abstract:: The Blanco Trough, a deep depression located in the Blanco Fracture Zone near the intersection with the Juan de Fuca Ridge, contains unusual manganese-enriched layered sediments. Due to the Blanco Trough's bathymetric isolation and confinement, and its location in a tectonically active zone, three hypotheses concerning the origin and cause...

Transmission efficiency and life table parameters of western flower thrips, Frankliniella occidentalis (Pergande) exposed to tomato spotted wilt virus-impatiens serotype

Creator:: Sether, Diane M.
Abstract:: Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint, initially observed in a research greenhouse (Corvallis, OR), included stunting and downward curling of leaves accompanied by bronzing, and occasionally tip necrosis. Young leaves appeared either symptomless, deformed, or...

Distribution of Oligonychus (Oligonychus) ununguis (Jacobi) (Acari: Tetranychidae) and predator mite species (Acair: Phytoseiidae) on field-grown Douglas-fir (Pseudotsuga menziesii [Mirb] Franco) Christmas trees

Creator:: Calkin, James D.
Abstract:: The shake and wash technique (samples placed in a jar with alcohol added and shaken to remove the mites) was effective in removing 100% of the predator mites, and adult spruce spider mites from Douglas-fir foliage and 98% of the spruce spider mite nymphs. Eighty-eight percent of the spruce spider...

Selenium measurement in ground water and biological material by instrumental neutron activation analysis

Creator:: Yousef, Samir
Abstract:: The utilization of ⁷⁷ [superscript m] Se, half life 17.5 s, and ⁷⁵ Se, half life 119.8 d, for quantification of trace amounts of Se in well water and biological materials by means of instrumental neutron activation analysis (INAA) is described.

An investigation of radioactively contaminated wastewater reclamation plant biosolids

Creator:: Brannan, C. Thomas
Abstract:: Within the last 15 years, wastewater treatment plants have increasingly begun to find radioactive isotopes incorporated in biosolids. Regulations concerning the disposal of radioactive material via sanitary sewer systems were in place since the early 1960's and recently were further restricted. However, the updated regulations would not have prevented certain...
