Researchers investigated the effectiveness of using internal screw fixation via the C1 and C2 pedicle in cases of old odontoid fractures and found the method provided an effective and safe surgical ...

NEW YORK — Results presented at the American Shoulder and Elbow Surgeons Annual Meeting showed button fixation had a significantly greater risk of recurrent shoulder dislocation but lower reoperation ...

(Nanowerk News) Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows ...

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University recently discovered a helicoidal-shaped ...

FOR a lesion that appears to be so simple, complete acromioclavicular dislocation can be one of the least satisfactory of traumatic injuries to treat. It is rarely difficult to reduce the dislocation ...

where b is the Burgers vector and D is the inter-dislocation spacing. · For the tilt boundary shown, the dislocations are straight edge type. For a pure twist boundary, an array of screw dislocations ...

Two-dimensional (2D) materials, such as graphene, have numerous practical applications in areas that include electronics in transistors, sensors and detectors; as battery and fuel cell electrodes; and ...

In metal alloys, behavior at the atomic scale affects the material's properties. However, the number of possible alloys is astronomical. Scientists developed a theoretical model that allows him to ...

In this paper, we consider dislocations in the framework of first as well as second gradient theory of elasticity. Using the Fourier transform, rigorous analytical solutions of the two-dimensional ...

Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes. Dr. Edwin L. Thomas, professor in the ...
