Flightfit: An Application Enabling Air Travelers To Do Stretches Onboard, Ninglin Jiang

Theses

Currently, with the development of economy and the improvement of people's living standards, more people would prefer traveling by air. However, sitting for extended periods of time on a long flight would be an uncomfortable joyless experience and it may have negative implications for health. A study from the World Health Organisation confirmed that the risk of developing venous thromboembolism (VTE) approximately doubles after travel lasting four hours or more. So carrying out some stretches frequently as well as standing up and moving around as often as possible under permitted conditions would help to improve blood circulation and relieve muscle …

Tone Reproduction In Virtual Reality, Antara Mishra

Theses

High dynamic range imaging has become very popular over the years in the field of computer graphics and games. The process of tone reproduction compresses the dynamic range of brightness in a scene to the lower range of display devices, thus making it an essential process in the graphics rendering pipeline. Various tone mapping operators have been tested for static viewing conditions. However, perceptual and temporal adaptation may vary for immersive viewing in a Virtual Reality environment. This thesis implements Ward et al. model (1994), Ward et al. model, Histogram Adjustment (1997) and Irawan, Ferwerda and Marschner model (2005) for …

Christian Theistic Anthropology, Anthony T. Vento

Doctoral Dissertations and Projects

At the present moment, which is prior to conducting any research, I am of the opinion that anthropology has been influenced by certain schools of thought, and each school’s definition establishes a trajectory which definitively determines the adherent’s worldview. The schools of anthropology which are prevalent in today’s world, in my estimation, are the evolutionist’s perspective, the hedonistic perspective, the rationalistic perspective, the dualistic perspective and the Christian perspective. I will seek to objectively and unbiasedly define each perspective’s understanding of man, then I will compare and contrast the main tenets of each school of thought, and finally, I will …

Hellhounds And Helpful Ghost Dogs: Conflicting Perceptions Of “Man’S Best Friend” Encoded In Supernatural Narrative, Kiersten Carr

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Black dogs are a type of spectral entity that, according to legend, have been haunting the British Isles for centuries. While the legends have many regional variations, the common feature remains a large black dog, often with eyes “large as saucers” or sometimes, flaming, who appears and then disappears, often without a trace. In many of the legends, the black dog is malevolent: assaulting travelers, frightening livestock to death, attacking other dogs, haunting graveyards and gibbets, and heralding death or disaster. In other versions, however, the black dog acts as a protector to those in need, warding off disaster with …

ZIKV and its close relatives, West Nile virus, Japanese encephalitis virus, dengue virus, and yellow fever virus are primarily transmitted by mosquitoes. Three ZIKVs were selected: MR-766 (Uganda, 1947), P6-740 (Malaysia, 1966), and PRVABC-59 (Puerto Rico, 2015), whose place of origin and time of isolation differ substantially. Stable, complementary DNA (cDNA) copies of the three ZIKV RNA genomes were cloned to examine the significance of viral and host genetic variations in directing ZIKV infection outcomes. Using …

Interactions Between Fire Severity And Forest Biota In The Central Sierra Nevada: Formation And Impact Of Small-Scale Fire Refugia And The Effect Of Fire On Forest Structure Predictive Of Fisher (Pekania Pennanti) Den Habitat, Erika M. Blomdahl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fire is a natural and essential component of forests in western North America. Fire maintains biodiversity through the creation of different habitat types, and regular fire rotations reduce the accumulation of woody fuels and thick understory plant densities that give rise to catastrophic fire. The practice of fire exclusion has altered western forests and increased the risk of widespread change under rising temperatures projected for the 21^st century. To manage for the reintroduction of fire it is critical that we understand the interactions between fire and forest biota in recently fire-suppressed forests.

In Chapter 2, I studied the formation …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In industry, antioxidants are added to prevent changes that affect quality due to oxidation, such as the development of off flavors, unacceptable odors and discoloration. New resources that are familiar to consumers and may work as antioxidants should be studied.

The changes in antioxidant activity were determined for four freeze-dried native wild berry powder species in Utah, including skunkbush (Rhus trilobata), chokecherry (Prunus virginiana), river hawthorn (Crataegus douglasii) and silver buffaloberry (Shepherdia argentea), during cold storage (-20 °C) for 6 months. The total antioxidant activity was stable in most of the berry …

Identification Of Sperm Chromatin Proteins As Candidate Markers Of Stallion Fertility, Chelsea C. Ketchum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During spermatogenesis, histones are largely replaced by transition proteins and protamines in normal stallions. Incomplete nucleoprotein exchange results in the abnormal retention of histones and transition proteins, which is an indicator of poor sperm quality. Equine nucleoprotein exchange has not previously been investigated in detail, so that equine sperm chromatin quality problems, which are often responsible for poor breeding performance of stallions, are not well understood. In order to characterize chromatin remodeling events in stallion spermatogenesis and to identify proteins indicative of sperm chromatin defects, such as excessive amounts of histones, we identified antibodies that recognize equine testis-specific proteins of …

Carbon Monoxide On Demand: Light-Induced Co Release Of Flavonols, Stacey N. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carbon monoxide (CO) is an extremely useful molecule with applications in industrial manufacturing, synthetic procedures as a C1 building block, and as a potential pharmaceutical to produce anti-inflammatory effects and vasodilation. However, the toxicity associated with CO has prevented its full utilization. In order to safely handle CO, compounds and molecules have been developed that act as storage materials for the gas. Ideal storage platforms only release CO upon stimulation via a trigger. Light activation is the most desirable trigger as it can be regulated in terms of the intensity and the wavelength of light used. The majority of light-induced …

The Macroinvertebrate And Fish Communities Of In-Stream Beaver Ponds In Northeastern Utah, Susan Washko

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Beavers were virtually extirpated from North America during the fur trade, but populations have since recovered. Dams built by recolonizing beaver alter stream habitat by forming deep, slow ponds within the streams. Such changes to the habitat is likely to have consequences for organisms such as macroinvertebrates and fish. The objective of this study was to identify the differences in the macroinvertebrate and trout community in beaver ponds and lotic (e.g. flowing reaches of a stream) reaches in tributaries to the Logan River in northeastern Utah. The macroinvertebrate community of beaver ponds had fewer species, fewer numbers, and lower biomass …
