An interactive computer graphics system applied to the life sciences

Creator:: Watson, Charles Ross
Abstract:: Graph production by computer requires a blending of human effort in scale selection with computer precision in datum point placement. Existing techniques are designed primarily for computer scientists; the average scientific investigator, educator, or businessman tends to avoid them for one or more of the following reasons: expense, complexity, or...

The NRF2-controlled Antioxidant Response, Alternative Forages, and Selenium supplementation for Improving Ruminant Productivity and Health

Creator:: Ford, Hunter
Abstract:: Oxidative dysfunction can affect dairy animals during periods of heightened stress, particularly during the transition from pregnancy to lactation and during diseases, such as intramammary infection (IMI), and can contribute to increased inflammation, immune dysfunction, and cell death. As such, methods for ameliorating oxidative stress and restoring redox regulation may...

The effect of a near-maximal effort one-hour run on preferred and optimal stride rate and vertical stiffness

Creator:: Hunter, Iain
Abstract:: Experienced runners naturally optimize stride rate in a manner that minimizes oxygen uptake at given running speeds. However, as runners become fatigued, preferred stride rate often decreases. Whether such changes with fatigue occur in parallel with changes in optimal stride rate is unknown. This study's focus was on determining whether...

The influence of canopy structure and epiphytes on the hydrology of Douglas-fir forests

Creator:: Pypker, Thomas G.
Abstract:: Canopy structure has a significant impact on the canopy hydrology of Douglas-fir forests in the Pacific Northwest (PNW). Whole canopy rainfall interception was measured for young Douglas-fir forest and compared to an old-growth Douglas-fir forest. The old-growth forest had significantly greater canopy water storage capacity (5) and direct throughfall fraction...

Size-related variation in tree growth and physiology

Creator:: McDowell, Nate G.
Abstract:: The goal of this dissertation was to improve our understanding of age-related constraints on aboveground production of forest trees. Previous research suggesting that carbon uptake of old trees is hydraulically constrained by tree size was used as the springboard for this research. Three specific working hypotheses were investigated: 1) compensation...

Cryopreservation of Shoot Tips: Antioxidant Investigations with Rubus and Protocols for Mentha and Vaccinium

Creator:: Uchendu, Esther Eyiuche
Abstract:: Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...

The performance of drivers with physical limitations at T-intersections

Creator:: Hunter-Zaworski, Katharine M.
Abstract:: The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

Evaluation of Rubus seed characteristics: seed coat morphology, anatomy, germination requirements and dormancy breaking

Creator:: Wada, Sugae
Abstract:: Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...

The Role of Facilitation for Maintaining Key Processes of Sagebrush-steppe Plant Populations in a Changing Climate

Creator:: Weisgerber, Elizabeth K.
Abstract:: Drought events have been shown to impact species distributions and are predicted to increase in frequency as the climate changes. As this occurs, ecologists predict species distributions will shift dependent upon species ability to track climate. These shifts in species distribution are expected to be particularly acute in arid and...

A qualitative study designed to explore some factors that white educators need to teach black students effectively

Creator:: Henry, Calvin Oscar Leon
Abstract:: The purpose of this study was to explore some of the factors White educators need to teach Black students effectively. It examined what role the race of the teachers may play in Black students' academic success and whether White teachers are able and willing to meet the educational needs of...
