Typical power outputs of commercially available diode lasers are on the
order of 5 milliwatts. This thesis discusses the growth, processing and
fabrication of high power (lOO's of milliwatts) diode lasers. Devices were
grown by Molecular Beam Epitaxy (MBE) and by Metal Organic Chemical
Vapor Deposition (MOCVD). The MOCVD diode...
The 2014 Working Group on California Earthquake Probabilities
(WGCEP14) present the time-independent component of the Uniform California
Earthquake Rupture Forecast, Version 3 (UCERF3), which provides authoritative
estimates of the magnitude, location, and time-averaged frequency of potentially
damaging earthquakes in California. The primary achievements have been to relax
fault segmentation and...
The 2014 Working Group on California Earthquake Probabilities (WGCEP 2014) presents time-dependent earthquake probabilities for the third Uniform California Earthquake Rupture Forecast (UCERF3). Building on the UCERF3 time-independent model published previously, renewal models are utilized to represent elastic-rebound-implied probabilities. A new methodology has been developed that solves applicability issues in...
Numerous evergreen trees and shrubs contain labdane acids, including isocupressic acid, which can cause
late-term abortions in cattle. Recent research has shown that the bark from western juniper trees can
also cause late-term abortions in cattle. Additionally, ranchers have observed that cattle in western juniper-infested
rangelands tend to have decreased...
Triathlon is an endurance sport consisting of back-to-back swimming, cycling, and running. There are four popular distances: sprint (.75k m swim, 20km bike, 5km run), Olympic (1.5km swim, 40km bike, 10km run), half-ironman (1.9km swim, 90km bike, 21.1km run), and ironman (3.8km swim, 180km bike, 42.2km run). Even at the...
Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...
U.S. foreign policy during the period between World War II and the Vietnam War has been described as part of a “nation-‐building” or “liberal” grand strategy. This thesis contends that understanding U.S. efforts to influence the internal affairs of sovereign states through the spread of liberal values and institutions during...
1,4-Dioxane (dioxane) is a probable human carcinogen and is often found comingled with chlorinated aliphatic hydrocarbon (CAH) contamination since dioxane is used as a stabilizer in CAH solutions. Dioxane is miscible in water, has a low K[subscript ow], low H[subscript cc], and is highly recalcitrant in the environment. The presence...
Kentucky bluegrass (Poa pratensis L.) cultivars are known to differ quantitatively in their photothermal floral inductive requirements. The extent to which these requirements are met influences the potential for subsequent panicle exsertion. A better understanding of the inductive requirements as they vary among cultivars would aid in the selection and...
A facility developed using the OSU TRIGA pulsing capability and high speed motion photography has been used successfully for more than a decade to produce dynamic neutron radiographs of solid propellant combustion, two phase flow, and liquid streamflow. The existing imaging components have undergone little modification since the experiment's inception...
