Biotribology: The Effect of Lubricant and Load on Articular Cartilage Wear and Friction
… presents a biotribological study on cartilage wear and friction, using a system of cartilage-on-stainless steel. This study is a part of the ongoing biotribology research by Dr. Furey at the Virginia Polytechnic Institute and State University. Two loads (65 N and 20 N) and three lubricants …

The Chipped Stone Tool Industries of Blackman Eddy, Belize
… Eddy using technological, attribute, and use-wear analysis. The data collected for this study were examined to see what types of raw materials were used in tool production, what types of tools were produced, how they were produced, and what they were used for during the Middle Preclassic, Late …

The fate of neonate calves. A discussion of the bovine infant health implications of dairying in antiquity, using archaeozoological studies of six Orcadian contexts.
… developmental stages in molariform teeth; tooth-wear methodologies are imprecise at this stage before wear commences. Known-age modern bovine foetal and neonate material are collected as a control assemblage for method development (n=73); six Neolithic to Norse era assemblages from Orkney are …

A COMPUTATIONAL APPROACH TO FRETTING WEAR PREDICTION IN TOTAL HIP REPLACEMENTS
… of contact geometry for a given application. “Wear” is one of a number of mechanical failures that can occur in mechanical coupling design. “Fretting wear” occurs where surfaces in contact are subjected to oscillating load and very small relative motion over a period of time. Fretting has been …

Late Classic and Epiclassic obsidian procurement and consumption in the southeastern Toluca Valley, Central Highland Mexico
… These artifacts were studied using an attribute analysis, chemical sourcing techniques, and use-wear analysis in order to address questions regarding changes in obsidian acquisition and consumption brought about by the demise of the city of Teotihuacan during the Late Classic. However, due to the …

Dental occlusal form and function in Equus capensis: evaluating a controvertible taxonomic status
… overall occlusal dental form. Finally, meso wear analysis was used to evaluate dental function. Analyses of dental occlusal enamel form were able to distinguish E. capensis teeth from those of equids in the comparative sample on the basis of size, but not shape. This result is telling since …
