The effects of multiple pathogens on amphibians in the Pacific Northwest

Creator:: Romansic, John M.
Abstract:: The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

Blood Processing Technologies for Cryopreserved Transfusion Products and Extracorporeal Treatment Applications

Creator:: Lahmann, John M.
Abstract:: There is a significant need for technological advancement in blood processing. New technologies in rapid processing of frozen blood products could significantly improve management of the blood supply chain in the United States by enabling on-demand use of frozen blood products that can be stored for 10 years instead of...

Development of Amorphous Metal Thin Films for Thermal Inkjet Printing and Microelectronics

Creator:: McGlone, John M.
Abstract:: Due to a lack of grain boundaries, an amorphous metal thin film (AMTF) possesses advantageous mechanical properties and enhanced chemical stability that is potentially useful for thermal inkjet (TIJ) printing applications. The use of an AMTF as a TIJ resistor or cavitation plate could lead to a thinner TIJ cavitation...

Phenotypic variation in diploid and tetraploid populations of Claytonia perfoliata (s.l.) (Portulacaceae)

Creator:: Miller, John M.
Abstract:: Meiotic chromosome counts from 200 populations of Claytonia (Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based on three morphologically different, chemically distinct, and geographically defined diploids. The basic chromosome number is x=6. Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid mature basal leaves ranges southeastward from...

The evolution of south Atlantic hot spot systems : an integrated geochronological and geochemical investigation

Creator:: O'Connor, John M.
Resource Type:: Dissertation

The cross-equatorial structure of tropical instability waves in sea surface height

Creator:: Lyman, John M.
Abstract:: A linearized model with two vertical modes has been developed to understand observed characteristics of monthly variability in the Equatorial Pacific from TOPEX/POSEIDON measurements of Sea Surface Height (SSH). The 2-mode model is obtained from an equatorial beta plane model that has been linearized about a geostrophically balanced mean flow...

The pectines of scorpions : analysis of structure and function

Creator:: Melville, John M.
Abstract:: This is a neuroanatomical and ethological study of the pectines, the primary chemosensory organs of scorpions (Arachnida: Scorpiones). The pectines are paired, ventromedial appendages that brush the substrate as the scorpion walks. This comb-like organ consists of a supportive spine and an array of teeth. Each tooth supports hundreds of...

An examination of relationships between hunting participation, family relations, and adolescent self-concept

Creator:: Baas, John M.
Abstract:: Recreation benefits are improved personal and social conditions which are thought to occur as a result of recreation participation. If these improved conditions can be adequately identified and measured, then they can be applied to recreation policy and planning decisions. Little research has been done on recreation benefits. Much of...

Stream channel response to peak flows in a fifth-order mountain watershed

Creator:: Faustini, John M.
Abstract:: This investigation explored how the magnitude, style, and frequency of channel adjustments vary spatially and over time within a 5th-order mountain watershed. Historical data sets, including repeated cross section surveys spanning up to 20 years at five sites on 2nd to 5th-order channels and streamflow records spanning up to 50...
