Inquiry focuses on the land use, mobility, technological organization, and raw material procurement of the aboriginal inhabitants of the area. Archaeological data presented here are augmented...
Force data for a flapping foil energy harvester with active leading edge motion operating in the low reduced frequency range is collected to determine how leading edge motion affects energy harvesting performance. The foil pivots about the midchord and operates in the low reduced frequency range of 0.06, 0.08, and...
This dissertation serves a threefold purpose: 1. identify the principles, practices and assumptions implicated in an academic theory of social justice; 2. continue moving towards articulating a theory of social justice judgment and decision making; and 3. develop a model of social justice judgment and decision making that will assist...

The frequency of aphid transmission of cucumber mosaic virus
from diseased plants at different times after inoculation was determined.
A cycle of infectious virus was found. Primary leaves
of lima bean plants were inoculated mechanically when the first trifoliate
leaf appeared and were kept at different temperatures. At
24° C...
The undermining of bridge foundations can lead to either costly repairs or a bridge
collapse. These foundations must be designed to counter the effects of scour. Current
practice does not allow for accurate estimates of scour in erodible rock. Scour in rock can be related to geotechnical and hydraulic properties....
