PURPOSE The use of graft tissue fixation using bioabsorbable interference screws (BISs) in anterior cruciate ligament (ACL) reconstruction offers various advantages, but limited pullout strength. Therefore, additional tibial fixation is essential for aggressive rehabilitation. We hypothesized that additional graft tissue fixation using bioabsorbable suture anchors (BSA) would provide sufficient...

We present measurements of the stress response of packings formed from a wide range of particle shapes. Besides spheres these include convex shapes such as the Platonic solids, truncated tetrahedra, and triangular bipyramids, as well as more complex, non-convex geometries such as hexapods with various arm lengths, dolos, and tetrahedral frames. All particles were 3D-printed in hard resin. Well-...

The present paper introduces a comprehensive model capable of describing the behavior of granular materials under cyclic loading. Its main thrust is the introduction of the “Chicago” law in a continuum approach to account for the ratcheting effects. It also emphasizes the rate-dependency as a dissipative mechanism which acts independently or jointly with the ratcheting effect. Non-associated pl...

Muscle and bone share numerous signaling pathways in the regulation of bone and muscle mass. However, of some crucial bone mass regulatory factors, such as RANKL, it is not known whether they are expressed in muscle, or whether they have an effect on muscle physiology. In addition, for some factors that are expressed in muscle and bone alike, i.e. COX-2, BMPs, Wnt signaling proteins, it is know...

Large-scale model tests were established at a scale of 1/5 using 7 m deep tank with cross-sectional dimension 5 × 4 m, to study the vibration response characteristics ballastless track, embankment, and X-section piled raft foundation under cyclic axial load, including displacement, velocity, dynamic soil, pile stress. Cyclic loading can be achieved by controlling frequency cycles through servo ...

• Experimental investigation of full-scale SRG jacketed columns under seismic loading. Alternative jackets were used differing in textile density and number layers. jacketing modified poor response from brittle bar buckling to flexural. Sufficient displacement ductility & low strength degradation observed up 5% drift. The effectiveness steel-reinforced grout (SRG) improving the structural perfo...

Although segmental tunnel linings are often used for seismic areas, the influence of segment joints on the segmental lining behavior under seismic loading has not been thoroughly considered in the literature. This paper presents the results of a numerical study investigating the effects of the rotational, axial, and radial joint stiffness of the longitudinal joints on the structural force...
