Ecology and Morphology of Early Animals: An Analysis of the Problematic Genus Sphenothallus from the Lower Cambrian Shuijingtuo and Niutitang Formations in South China
(Virginia Tech, 2009-08-19)
New specimens of the problematic group Sphenothallus have been recovered from the early Cambrian Shuijingtuo and Niutitang Formations in South China. The two sites from the Shuijingtuo Formation were collected from Yanjiahe ...
motus et re-creation: Movement and re-creation on accotink creek
(Virginia Tech, 2011-06-24)
Speed has long been equated with "progress". The Romans' paved roads begot much of this concept, allowing faster travel that improved communication, commerce, and enabled control over vast territories. Additionally paved ...
The Effects of Trained Facilitation of Learning-Oriented Feedback on Learner Engagement, Performance, Self-Efficacy, and Enjoyment
(Virginia Tech, 2003-08-29)
The level of learner engagement, performance, self-efficacy, and enjoyment on a knot-tying task by college students who received positive verbal and non-verbal learning-oriented feedback by trained facilitators was examined. ...
The role of dispersal networks in structuring biotic communities: A tale of streams and metacommunity theory
(Virginia Tech, 2016-06-01)
Identifying the processes and mechanisms that govern communities of organisms is the main goal of community ecology. Locally operating mechanisms such as environmental filtering, in which the environment determines what ...
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 ...
