“Removing the nail from the coffin'' outcomes of intramedullary nailing of femur fractures: a comparison of anterograde- and retrograde nails
… population. In the past, intramedullary femur nails were primarily performed utilising the anterograde approach (AFN). Recently, the retrograde approach (RFN) has become an attractive alternative option. The retrograde approach requires no traction table during surgery, a viable solution where, …

Relationships between MIBANT bend angles and selected material properties of pallet fasteners
… Static yield strength values for pallet nails were found to values (p > 0.0001 be linearly related to the dynamic 2 and R² = 0.950) and hence MIBANT bend angles. Static yield strength values were also related to MIBANT bend angles (p > 0.209 and R² = 0.896) for staples. The Vickers …

Evaluation of improved stevedore pallet
… of two designs assembled with four different nails. Special consideration was given to Brazilian situations in the light of the interest of the author in the industrial potential of Brazil. The pallets of improved design had their top and bottom leading-edge deckboards backed up by follow-up …

Experimental analysis of king-post truss with semi-rigid joints
… plywood gusset plates using helically threaded nails to form roof trusses has been widely developed in recent years. Actually, the nailed member has proven to be extremely strong and stiff, but it is not perfectly rigid. The effect of non-rigidity of joints in resisting bending and thrust are …

Ornamenting Fingernails and Roads: Beautification and the Embodiment of Authenticity in Post-War Eastern Sri Lanka
… everyday exchanges from how women ornament their nails to how communities beautify their open—and sometimes contested—spaces. I draw on my ethnographic data from Eastern Sri Lanka and explore ‘color’ as negotiated through personal and public ornaments and notions of beauty with a material culture …
