Utilization of the Zebrafish Model for Investigating Nitrated Polycyclic Aromatic Hydrocarbon Developmental Toxicity

Creator:: Chlebowski, Anna C.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are among the most widely known and studied environmental contaminants, originating from a range of natural and anthropogenic sources. PAHs are known to occur in the environment as complex mixtures, containing both unsubstituted PAHs, as well as a range of PAH derivatives. Among the less-studied of...

Abstract:: Fecal glucocorticoid metabolites (FGMs) are commonly used as indicators of an animal’s stress response in behavioral and eco-physiological studies. Stress in wild animals represents an immediate measure of the physiological response to changes in the environment, and, potentially, a prospective assessment of the animal’s health and well-being. In wild mammals,...

Patch dynamics of desert fishes in the arid wetlands of western Utah

Creator:: Sáenz, Jessica
Abstract:: The conservation of declining desert fish species requires the identification of relations between fish population dynamics and their environments. Dynamic occupancy modeling, an approach that requires less information than traditional mark-recapture studies, may help identify important factors affecting population processes and aid desert fish conservation and restoration efforts. I used...

Patient radiation exposure variability and minimization in mobile, C-arm fluoroscopy

Creator:: Van Wieren, Robert T.
Abstract:: BACKGROUND: The frequency of C-arm fluoroscopy procedures is increasing and it has become prudent to increase the awareness of patient radiation exposure to minimize patient risk. There is a strong potential for variability in patient exposure levels and a need for minimizing unnecessary exposure. The variability in C-arm fluoroscopy can...

Road user understanding of shared lane pavement markings (sharrows) case study - Corvallis, OR

Creator:: Cosma, Ioana
Abstract:: This thesis focuses on shared use lane facilities and road user understanding. Shared use lanes (sharrows) are a common solution for road facilities that are too narrow to accommodate a full bicycle lane and where the local jurisdiction wants to reduce dooring crashes. In recent years, engineers have focused on...

Atmospheric Radon Modeling for Aerial Measurements

Creator:: Owensby, Brittany N.
Abstract:: The Ariel Measuring System (AMS) is a national asset in responding to radiological or nuclear events. The AMS operates out of several aerial platforms, such as the BK-117 helicopter and the P3 Long Range Tracker, under many equipment configurations. Measurements can be telemetered real time to reach back for evaluation...

An analysis of the viability of ranked set sample methodologies based on the evaluation of Dyess AFB B-47 crash site radiological contamination survey data and theoretical modifications

Creator:: Miller, Vivien J.
Abstract:: Since Ranked Set Sampling (RSS) was proposed in 1952 by G.A. McIntyre, it has been the subject of many statistical investigations and a large number of field studies. Throughout these studies RSS has been proven to provide a better estimate of population the mean and variance than Simple Random Sampling...
