Efficient Finite Groups Arising in the Study of Relative Asphericity

Creator:: Bogley, William A. and Williams, Gerald
Abstract:: We study a class of two-generator two-relator groups, denoted J[subscript n](m, k), that arise in the study of relative asphericity as groups satisfying a transitional curvature condition. Particular instances of these groups occur in the literature as finite groups of intriguing orders. Here we find infinite families of non-elementary virtually...

The Effect of Flowrate on Trapping in a Two-phase System as it Relates to CO₂ Sequestration

Creator:: Williams, Kristal A.
Abstract:: This research examines the independent and combined effects of drainage and imbibition flowrate on nonwetting phase capillary trapping in a two-phase, porous medium system. A uniform system of cubic arrangement and non-uniform systems of both cubic and rhombohedral arrangements were examined in order to analyze and compare the nonwetting phase...

Evaluating the impacts of a classroom-based citizen science project on nature connectedness, science identity, and knowledge of curricular material

Creator:: Williams, Katherine A.
Abstract:: Environmental education programs seek to foster an appreciation for the natural world while introducing students to scientific thinking. Citizen science engages non-scientists in the systematic collection and analysis of data. The Betts Forest Landscape Ecology Lab combines both goals by inviting teachers in Corvallis, Oregon, and surrounding areas to participate...

The Development of Astronomy in the United States Prior to 1900

Creator:: Harburg, William A.
Abstract:: From the earliest English colonization to the present day, there has been interest in astronomy in this country. The purpose of this thesis is to show how the science of astronomy developed in America from the earliest observations by educated colonists using imported instruments and publishing in European journals, to...

Restoration of Tillamook Bay : Project Planning

Creator:: Hevlin, William A.
Abstract:: The objective of this project is the production of a Tillamook Bay restoration plan which is designed to revitalize the bay's biological productivity and thereby stimulate economic opportunity in the region. A selected planning team will assess the cumulative impacts on the bay from accelerated sedimentation. The team will develop...

Multiyear Advanced Very High Resolution Radiometer observations of summertime stratocumulus collocated with aerosols in the northeastern Atlantic

Creator:: Matheson, Mark A., Coakley, James A., and Tahnk, William R.
Abstract:: Advanced Very High Resolution Radiometer (AVHRR) 4-km data were collected over the northeast Atlantic for May–August 1995–1999. Aerosol optical depth at 0.55 μm was retrieved in pixels identified as being cloud-free ocean. In pixels identified as containing clouds from single-layered, low-level cloud systems over oceans, the following cloud properties were...

Measurement of Condensed Water Content in Liquid and Ice Clouds Using an Airborne Counterflow Virtual Impactor

Creator:: Twohy, Cynthia, Schanot, Allen J., and Cooper, William A.
Abstract:: Condensed water content (CWC) measured using a counterflow virtual impactor (CVI) with a Lyman-α hygrometer downstream is compared with that measured by other airborne instruments (a hot-wire probe, a PMS FSSP, and a PMS 2D-C). Results indicate that the CVI system provides a reliable measurement of CWC in both liquid-...

Morning-to-Afternoon Evolution of Marine Stratus Polluted by Underlying Ships: Implications for the Relative Lifetimes of Polluted and Unpolluted Clouds

Creator:: Christensen, Matthew W., Coakley, James A., Jr., and Tahnk, William R.
Abstract:: Ship tracks appearing in both the morning and afternoon Moderate Resolution Imaging Spectroradiometer (MODIS) imagery for the Pacific Ocean off the west coast of the United States were used to study the morning-to-afternoon evolution of marine stratus polluted by underlying ships and nearby uncontaminated stratus. Analyzed 925-hPa winds were used...

Reference Gene Selection for Quantitative PCR Studies in Sheep Neutrophils

Creator:: Vorachek, William R., Hugejiletu, Bobe, Gerd, and Hall, Jean A.
Abstract:: Reference genes are essential for studying mRNA expression with quantitative PCR (qPCR). We investigated 11 potential neutrophil reference genes (RPL19, GAPDH, ACTB, B2M, HPRT, G6PD, TFRC, PGK1, YWHAZ, SDHA and GYPC) for sheep under disease conditions of foot rot (FR) and with or without Se supplementation. Initial screening was based...

Aerosol optical depths and direct radiative forcing for INDOEX derived from AVHRR: Theory

Creator:: Coakley, James A., Jr., Tahnk, William R., Jayaraman, A., Quinn, Patricia K., Devaux, Claude, and Tanré, Didier
Abstract:: A scheme is presented for retrieving aerosol properties for ocean regions from reflected sunlight at both the visible and near infrared wavelengths measured by the NOAA advanced very high resolution radiometer (AVHRR). For the Indian Ocean Experiment (INDOEX), aerosols were presumed to be a mixture of a continental haze that...
