The etiology of root rot and decline of English boxwood (Buxus sempervirens cv. surfruticosa L.)
(Virginia Polytechnic Institute and State University, 1975)
Analysis, finite element approximation, and computation of optimal and feedback flow control problems
(Virginia Tech, 1994-07-05)
The analysis, finite element approximation, and numerical simulation of some control problems associated with fluid flows are considered. First, we consider a coupled solid/fluid temperature control problem. This optimization ...
Understanding the Islamic conversion experience of two African American males: a case study approach to decision making toward transformational change
(Virginia Tech, 1996-05-04)
Islamic conversion among African Americans is a unique 20th-Century phenomenon. African Americans represent 42% of the total Muslim population in America. This research study describes the life experience and decision ...
An investigation of shear response of composite material systems
(Virginia Tech, 1994)
Theoretical and experimental studies of energy transfer dynamics in collisions of atomic and molecular species with model organic surfaces
(Virginia Tech, 2009-04-01)
A full understanding of chemical reaction dynamics at the gas/organic-surface interface requires knowledge of energy-transfer processes that happen during the initial gas/surface collision. We have examined the influence ...
Obstructive Sleep Apnea Risk in Abdominal Aortic Aneurysm Disease Patients: Associations with Physical Activity Status, Metabolic Syndrome, and Exercise Tolerance
(Virginia Tech, 2013-05-03)
Obstructive sleep apnea (OSA) is common in older U.S. adults and the prevalence is anticipated to rise in this age group along with obesity, a prominent risk factor for OSA. Recently, OSA was determined to be highly prevalent ...
Supporting Learning through Spatial Information Presentations in Virtual Environments
(Virginia Tech, 2013-06-11)
Though many researchers have suggested that 3D virtual environments (VEs) could provide advantages for conceptual learning, few studies have attempted to evaluate the validity of this claim. While many educational VEs share ...
Growth Factor and Extracellular Matrix Regulation of Heifer Mammary Development
(Virginia Tech, 2002-08-02)
The overall objective of this project was to investigate the role of locally derived growth factors and extracellular matrix proteins in regulating prepubertal heifer mammary development. In the first experiment, short-term ...
Essays on Rural-Urban Migration in China
(Virginia Tech, 2006-05-10)
Since the late 1980â s, China has experienced the worldâ s largest peacetime out-migration of its rural labor force to urban areas. The temporary nature of the labor migration complicates the control on this mobile ...
Identification and Characterization of Genes Involved in Regulation of Ascorbate Metabolic Pathway(s) in Arabidopsis thaliana
(Virginia Tech, 2007-02-01)
Vitamin C (ascorbic acid, AsA), an important primary metabolite of plants, functions as an antioxidant, an enzyme cofactor, and a cell-signaling modulator in a wide array of crucial physiological processes including ...
