ABSTRACT Technological analysis of the late Holocene component of the stone artefact assemblage recovered from the Kings Table rockshelter in the Blue Mountains, west of Sydney, provides the basis for an assessment of the site's role in broader late Holocene settlement‐subsistence systems. Drawing on Kuhn's widely employed “provisioning model”, as well

Amination of Polymeric Braid Structures to Improve Tendon Healing: An Experimental Comparison
Poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA) are polymers useful in tendon repair, though with minimal success. There is a need to improve such scaffolds' design and physical–chemical nature. The work concerns functionalization of PET/PLA braids to incorporate amine groups in the braids' surface, improve cell adhesion, and ...
