The purpose of this study was to determine the optimal thread shape for an experimental cylinder implant. Twelve three-dimensional finite element models with an implant of different thread shape were created: 1mm, 2mm, and 3mm square designs (S-1, S-2, and S-3); 90, 60, and 30 V-shaped designs (V-1, V-2, and V-3); 45, 30, and 15 buttress designs (B-1, B-2, and B-3); 45, 30, and 15 reverse buttr...
Objective To compare the obstetric outcomes of cesarean section in women who had a history of four or more previous cesarean sections with those who had a history of two or three previous cesarean sections. Methods Total 1318 women who underwent repeat cesarean section between January 2013 and January 2016 were retrospectively reviewed. Of these, 244 (18.5%) had previously had four or more ce...
there have been some experimental tests on hollow curved-steel struts with thin-walled square sections, in order to investigate their general behavior, particularly their capacity for bearing differing loads. one set of square tubes are cold-formed into segments of circular arcs with curvature radii, equal to 4000 mm. different lengths of curved struts are fabricated so as to cover a practical ...
In the nonlinear theory of isotropic elastic materials, there are relations between force-like quantities and deformation-like quantities which are independent of material properties. Such relations have been called "universal" relations [1]. The best known example is that of Rivlin for simple shear [2]. It relates components of normal and shear stress and the amount of shear. Another important...
