Blast-related lower extremity trauma presents many challenges in its management that are not frequently experienced in high-energy civilian trauma. Because many of the blasts experienced in the current conflicts are ground based, the foot and ankle have sustained considerable severity and extent of injury because of the proximity of the blast. The high functional demands required of active serv...

At high frequency, the winding losses of power transformer due to skin and proximity effects becomes a significant component in the loss calculation of the transformer efficiency. This paper examines the winding losses associated with these effects for planar-type low-profile transformers that are suitable for high frequency high density soft switching power supply application. The transformer ...

An asymmetric Mannich reaction of phenylacetate thioesters and sulfonylimines using cinchona alkaloid-based amino (thio)urea catalysts is reported that employs proximity-assisted soft enolization. This approach to enolization is based on the cooperative action of a carbonyl-activating hydrogen bonding (thio)urea moiety and an amine base contained within a single catalytic entity to facilitate i...

We consider a low T_{c} metallic superconductor weakly coupled to the soft fluctuations associated with proximity to a nematic quantum critical point (NQCP). We show that (1) a BCS-Eliashberg treatment remains valid outside of a parametrically narrow interval about the NQCP, (2) the symmetry of the superconducting state (d wave, s wave, p wave) is typically determined by the noncritical interac...

Reconstruction of large soft tissue defects of the medial canthal area represents a challenge, because of the thin skin, concave contour, and proximity to important nearby structures. Tension-free closure is important in avoiding distortion of the eyelid and nasal ala. Skin graft closure is not aesthetically appealing, and there are limitations in the use of local tissues for reconstruction. We...

The manipulability index is used to quantify manipulators velocity transmission capabilities or the dexterity of robot. The index is a measure of manipulating ability of robotic mechanisms in positioning and orienting the end effectors. The index allows to quantify the proximity of the robot to a singularity, which is ideal for identifying paths of welding with continuous and soft movements at ...

BACKGROUND A 55 year old gentleman presented with tardy posterior interosseous nerve palsy associated with radial head fracture. CASE PRESENTATION The patient developed symptoms of wrist drop 24 hours after the injury whilst awaiting surgery for his Mason III radial head fracture. EMG studies confirmed the presence of a posterior interosseous nerve lesion. Open exploration revealed oedematous...

We report on mid-infrared observations of the compact stellar cluster located in the proximity of SGR 1900+14, and the radio/X-ray position of this soft-gamma repeater. Observations were performed in May and June of 2001 when the bursting source was in an active state. At the known radio and X-ray position of the SGR we did not detect transient mid-IR activity, although the observations were pe...

Hemangiomas are benign vascular tumors which represent a rapid growth pattern followed by the involution phase. Generally, they are located in the soft tissues and are usually diagnosed in the first decade of life. Hemangiomas are mostly asymptomatic and rarely affect jaw bones. Mandible is affected more often than maxilla. If there is no complication present, treatment may not be necessary. Tr...

Conventional nonsurgical endodontic treatment has a high degree of clinical success, but in certain cases surgical intervention becomes necessary. This is the case report of a patient presenting with bilaterally separate periapical lesions in the maxillary anterior region. One lesion was managed by periapical surgery using a novel and safe method of separating the soft tissue mass of the periap...
