The composites were prepared by diluting masterbatch (15 wt.% MWCNT) using a Haake mixer and then injection-molded into a dog-bone mold.
The work presented here adds to this experimental butchery database by using measurements of cut mark cross-section taken from bone surface molds to investigate how stone tool characteristics including flake versus core tool type, edge angle, and tool weight, influence cut mark width and depth, ultimately testing whether cut mark size is a useful indicator of tool identity.
Briefly, a small biopsy of substantia spongiosa osseum, which otherwise would have been discarded based on necessary bone for molding and re-contouring prior to insertion into the recipient site, was taken to further investigation under an Institutional Review Board-approved protocol after having obtained the parents' and the respective patient's written consent.
Each block containing bones was molded and cast to create an archive of the position of the bones as found in the field.
The collagen-cell solution was pipetted into custom-made dog-bone-shaped molds (3 mm thick), fabricated to be 15 mm in width at the grips with a 5-mm-wide × 10-mm-long gauge region, placed in petri dishes.
Moreover, PLA9 has the greatest desirability among the selected materials for bone screw injection molding.
After suture, the graft bone site was molded with a finger to shape appropriate forms (Fig. 1).
Found in Wyoming, this new skeleton from the Late Cretaceous Period is a product of traditional bone replication by molding and casting, as well as three-dimensional laser scanning and prototyping that fixes many inaccuracies in the original mount.
Mold bones on the wires using the plumbers epoxy putty.
We spread the doughy bone cement in a polytetrafluoroethylene mold after which the mold was compressed between two glass plates and covered with copier overhead film (MC 110, Océ, The Netherlands) to facilitate removal after hardening.
This material included tools, slivers and worked fragments of ivory and bone, glass ornaments, and molds.
