[Proximal avulsion of the rectus femoris muscle].

Background: Injuries of the thigh muscles are among the most frequent sports injuries. For example, in soccer they represent nearly 30% of all injuries. The rectus femoris muscle is particularly exposed to injury due to its anatomical features.

[Proximal avulsion of the tendon of the rectus femoris muscle : Case description and literature review].

Injuries of the thigh muscles are among the most common sports injuries. In soccer they represent nearly 30% of all injuries. The rectus femoris muscle in particular is often exposed to injuries due to its anatomical features.

Multicolor emission from intermediate band semiconductor ZnOSe.

Photoluminescence and photomodulated reflectivity measurements of ZnOSe alloys are used to demonstrate a splitting of the valence band due to the band anticrossing interaction between localized Se states and the extended valence band states of the host ZnO matrix. A strong multiband emission associated with optical transitions from the conduction band to lower E and upper E valence subbands has been observed at room temperature. The composition dependence of the optical transition energies is well explained by the electronic band structure calculated using the kp method combined with the band anticrossing model.

Direct Measurements of Fermi Level Pinning at the Surface of Intrinsically n-Type InGaAs Nanowires.

Surface effects strongly dominate the intrinsic properties of semiconductor nanowires (NWs), an observation that is commonly attributed to the presence of surface states and their modification of the electronic band structure. Although the effects of the exposed, bare NW surface have been widely studied with respect to charge carrier transport and optical properties, the underlying electronic band structure, Fermi level pinning, and surface band bending profiles are not well explored. Here, we directly and quantitatively assess the Fermi level pinning at the surfaces of composition-tunable, intrinsically n-type InGaAs NWs, as one of the prominent, technologically most relevant NW systems, by using correlated photoluminescence (PL) and X-ray photoemission spectroscopy (XPS).

Long-term outcome of chevron-osteotomy in juvenile hallux valgus.

The long-term outcome of juvenile hallux valgus treated by a modified Austin procedure was investigated. The clinical (subjective, AOFA Scores) and radiological outcome (hallux valgus angles, intermetatarsal angles, position of the sesamoid bones and metatarsal index of 15 feet in 12 patients, aged 14 years and 2 months (SD +/- 1 year 10 months) were assessed pre- and postoperatively and after 7 years and 3 months (SD +/- 3 years). A significant improvement of the hallux valgus angle and of the intermetatarsal angle was obtained, persisting until final follow-up.
