Perturbed angular correlation (PAC) spectra of fully yttria-stabilized (cubic) zirconia with Y₂0₃ contents of 35.4 wt. %, 27.8 wt. %, and 16.9 wt. %, respectively, were measured using the isotope ¹⁸¹Ta as probe nucleus. PAC spectra in cubic zirconia are characterized by a wide frequency distribution due to contributions of...
High impact loading activities such as jumping, performed during childhood is advocated as one preventive method for increasing peak bone mass. Thus, we conducted a randomized intervention to examine the effect of high impact loading on bone mass in 34 pre-pubescent boys and girl over a seven month period. Participants...
Methane is a flammable gas that is the main component of natural gas. It is a highly potent greenhouse gas, and accounts for about 20% of greenhouse gas emissions. Methane is routinely flared in many industrial processes without harnessing any of its energy. The environmental impact and wasted energy potential...
To examine the potential for exercise to build bone mass during growth, objectives of this dissertation included: 1) determine the effects of 7 months of jumping followed by 7 months of detraining on hip and spine bone mass in the prepubertal children; 2) determine variables that best predict bone mineral...
Hemp (Cannabis sativa L.) is a versatile crop with a wide range of pharmaceutical, commercial, and industrial uses. There is a lack of research and published studies on the ideal storage conditions and their effects on seed quality for hemp. Understanding ideal hemp seed storage conditions would reduce unnecessary seed...
A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...
Recently, an interest in supplementation of vitamin D to improve aspects of health, especially in human fertility, has emerged. However, supplementation of Vitamin D above the minimum required levels to prevent deficiency has yet to be explored in cattle despite evidence for vitamin D receptors in reproductive tissues. The objective...
Cutaneous melanoma remains the deadliest form of skin cancer arising from malignant transformation of pigment-producing melanocytes, with a diagnosis of metastasis indicating a median survival rate of less than a year. Solar ultraviolet (UV) radiation, especially childhood sun exposure, is an important etiological risk factor of melanoma. This DNA damage...
