Are Radio Sources And Gamma Ray Bursts Luminal Booms?, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

The softening of a Gamma Ray Burst (GRB) afterglow bears remarkable similarities to the frequency evolution in a sonic boom. Atthe front end of the sonic boom cone, the frequency is infinite, much like a GRB. Inside the cone, the frequencyrapidly decreases to infrasonic ranges and the sound source appears at two places at the same time,mimicking the double-lobed radio sources. Although a “luminal” boom violates the Lorentz invarianceand is therefore forbidden, it is tempting to work out the details and compare them with existing data. This temptation is further enhanced by the observed superluminality in the celestial objects associated …

Mechanical Fatigue In A Magnetically Levitated Axial Blood Pump, Amy Slevar

Theses

This research investigated some of the mechanical fatigue associated with the use of a rotary pump as a left ventricular assist device, LVAD, for long term therapy (>20 years). In this magnetically levitated axial pump, we identified one feature most susceptible to mechanical stress and fatigue. the thin-sectioned inducer blade is made of titanium and is the first point of contact between the housing and impeller should the levitation system momentarily lose control. !e inducer blade is also long and thin and will experience both normal and bending loads when contacted by the impeller. The incidence of contact and …

Trivalent Vaccine Against Botulinum Toxin Serotypes A, B, And E That Can Be Administered By The Mucosal Route, Easwaran Ravichandran, Fetweh H. Al-Saleem, Denise M. Ancharski, Mohammad D. Elias, Ajay K. Singh, Mohammad Shamim, Yujing Gong, Lance L. Simpson

Department of Medicine Faculty Papers

Most reports dealing with vaccines against botulinum toxin have focused on the injection route of administration. This is unfortunate, because a mucosal vaccine is likely to be more efficacious for patients and pose fewer risks to health care workers and to the environment. Therefore, efforts were made to generate a mucosal vaccine that provides protection against the botulinum serotypes that typically cause human illness (serotypes A, B, and E). This work demonstrated that carboxy-terminal peptides derived from each of the three serotypes were able to bind to and penetrate human epithelial barriers in vitro, and there was no cross inhibition …

Development Of Cursor-On-Target Control For Semi-Autonomous Unmanned Aircraft Systems, Joshua D. Crouse

Theses and Dissertations

The research presented in this thesis focuses on developing, demonstrating, and evaluating the concept of a Cursor-on-Target control system for semi-autonomous unmanned aircraft systems. The Department of Defense has mapped out a strategy in which unmanned aircraft systems will increasingly replace piloted aircraft. During most phases of flight autonomous unmanned aircraft control reduces operator workload, however, real-time information exchange often requires an operator to relay decision changes to the unmanned aircraft. The goal of this research is to develop a preliminary Cursor-on-Target control system to enable the operator to guide the unmanned aircraft with minimal workload during high task phases …

Systems Metaphysics: A Bridge From Science To Religion [Presentation], Martin Zwick

Complex Systems Faculty Publications and Presentations

'Systems theory' is familiar to many as the scientific enterprise that includes the study of chaos, networks, and complex adaptive systems. It is less widely appreciated that the systems research program offers a world view that transcends the individual scientific disciplines. We do not live, as some argue, in a post-metaphysical age, but rather at a time when a new metaphysics is being constructed. This metaphysics is scientific and derives from graph theory, information theory, non-linear dynamics, decision theory, game theory, generalized evolution, and other transdisciplinary theories. These 'systems' theories focus on form and process, independent of materiality; they are …

Sod Webworms, Erin W. Hodgson, Alan H. Roe

All Current Publications

The term “sod webworm” refers to an insect complex of more than twenty different grass-infesting species. Adult sod webworms are pyralid moths, but are more commonly referred to as “snout moths” because their mouthparts are projected forward (Fig. 1). Sod webworms are distributed through the U.S., and at least seven different species occur in Utah (Table 1).

Cranberry Girdler, Erin W. Hodgson, Alan H. Roe

All Current Publications

Cranberry girdler, Chrysoteuchia topiaria, can be found throughout the U.S., but is particularly damaging to turfgrass seed production areas in the Pacific Northwest. This insect was first detected in northern and northeastern Utah during the early 1980’s. Larvae prefer cool-season grasses, such as Kentucky bluegrass, bentgrass and fine-leaf fescues. In addition to causing significant damage to turfgrass, it is recorded as a pest of other grasses, cranberry, Douglas fir, and true firs.

Neural Defects And Cardiac Arrhythmia In Fish Larvae Following Embryonic Exposure To 2,2',4,4'-Tetrabromodiphenyl Ether (Pbde 47), Sean C. Lema, Irvin R. Schultz, Nathaniel L. Scholz, John P. Incardona, Penny Swanson

Biological Sciences

Polybrominated diphenyl ethers (PBDEs) are added to plastics, polyurethane foam, and textiles as a flame retardant. While PBDEs play a key role in reducing loss of human life and property from fires, these flame retardants have become pervasive organic contaminants in the environment and in the tissues of fish, birds, marine mammals, and humans. Levels of PBDEs in wildlife and humans continue to rise, raising concerns about potential ecological and health risks associated with exposure to these chemicals. Nevertheless, there is little currently known about the toxicological effects of PBDE exposure. Here, we examined the developmental toxicity of the PBDE …

In Vitro Feasibility Testing Of Floating Light-Activated Minroelectrical Stimulators, Ammar Riad Abdo

Theses

One of the major challenges of neural stimulation is the mechanical stress and resulting trauma induced on the implanted electrodes by the constant movement of the interconnects. A potential way of eliminating interconnects is to use floating micro-stimulators that can be activated through optical means. As a method of energy transfer to the micro-stimulator, we propose to use a laser beam at near infrared (NIR) wavelengths.

There are two main objectives in this project to test the feasibility of the main approach; investigate the charge injection capacity of titanium nitride (TiN) and iridium oxide (IrOx) as potential contact materials, and …
