BACKGROUND Osteoconductive additives are used in resorbable interference screws for anterior cruciate ligament (ACL) reconstruction to improve graft incorporation and mitigate adverse effects. There are no published studies that compare biological performances of bioresorbable and biocomposite screws without artifacts due to different follow-up times and intrinsic patient characteristics. PUR...

This paper presents results of micromagnetic simulations of magnetization switching driven by spin-polarized current in magnetic tunnel junctions. For the studied structures, and for all the simulated currents, the switching occurs via nucleation process. A complete study of how a misalignment of the applied field and nonidealities in the shape of the sample affect the switching behavior has al...

The tunnel is one of the most important components in modern underground engineering. Due to long and narrow shape constraints, it very easily results large-scale fire explosion when deflagration caused by accidents vehicles that transport dangerous goods tunnel. Previously, studies on damage lining high-temperature impacts these kinds disasters were often limited a discussion only influencing ...

We report the current-voltage behavior for nanoscale point contacts to Si(111) obtained in ultrahigh vacuum using scanning tunneling microscopy. Epitaxial CoSi(2) islands provide single-crystal contacts with well-defined size and shape. The zero bias conductance is found to be independent of the island size (10(2)-10(4) nm(2)) and shape, but varies strongly with the surface Fermi level position...

Structural instability caused by self exciting aerodynamic forces (flutter) can be used as an effective input source for small scale energy harvesters. The self exciting aerodynamic force exerted on a T-shape cantilever causes periodic vibration, which can be converted into electric power through an electromagnetic transducer. Due to the complexities inherent in the fluid-structure interaction ...

The effects of varying the angle of wind velocity and axis of a cylindrical icing object around all of the three mutually perpendicular axes are studied experimentally. The mass, shape and profile of ice accretion obtained in a horizontal icing wind tunnel are investigated as functions of cylinder inclination. The icing object is exposed to two types of aerosol cloud, which are created by diffe...

this presentation will cover, appearance of normal nerve versus tendon; anisotropy (advantage and disadvantage); special case carpal tunnel; tendinopathy; nerve impingement; special case cubital tunnel.

Tunnel Broker model, as defined in RFC3053, is a solution to the automation of IPv6 address assignment and IPv6 over IPv4 tunnel management. Tunnel server selection and fault tolerance are two big problems for a Tunnel Broker system. Anycast makes it possible to solve the tunnel server selection problem and improve the system’s fault tolerance. This paper proposes an architecture of the Tunnel ...
