Abrasive Wear Assessment of X70 Steel and Polyurethane Coupons on a Modified Dry/Sand Rubber Wheel Apparatus
DownloadFall 2013
An experimental study was conducted to assess the scratching abrasion in dry and wet environments on X-70 steel and five different types of titanium carbide particulate polyurethane composites (PU). A testing apparatus was constructed based on the dry sand rubber wheel test method standardized by...

Three-Dimensional Bookstein Shape Coordinates and Functional Morphology of Passive Suspension Feeding in Composita (Brachiopoda, Athyridida)
DownloadSpring 2014
The effects of shell morphology on passive fluid circulation are examined in Late Mississippian through Late Pennsylvanian Composita (Brachiopoda, Athyridida) from Texas, Kentucky, and Iowa. The first three-dimensional derivation of Bookstein shape coordinates is given in association with an...
