A preliminary aerodynamic and thermodynamic analysis of a supersonic propeller driven by an electric motor is performed. The aimed at determining whether such system feasible further more detailed investigation warranted. Recent progress in energy storage motors, as well high temperature lightweight materials, has opened up the design space for large number applications. Electrically powered fl...

  The management of soft tissue defects in tibial fractures is essential for limb preservation. Current techniques are not without complications and may lead to poor functional outcomes. A salvage method is described using three illustrative cases whereby a combination of flaps and antibiotic-impregnated polymethylmethacrylate beads are employed to fill the bony defect, fight the infection, and...

e welcome the interest of Drs. Rapezzi and colleagues in our rticle (1). We did not discuss radionuclide imaging of amyloid ith tracers developed for bone scintigraphy because few data are vailable and because of constraints of space. Bone scintigraphy in myloidosis has been evaluated systematically only in very small eries (2), and there is no evidence as yet for a specific molecular nteractio...

Marijuana has been proposed as treatment for a widening spectrum of medical conditions. Marijuana is a substance with many properties that may be applicable to the management of amyotrophic lateral sclerosis (ALS). These include analgesia, muscle relaxation, bronchodilation, saliva reduction, appetite stimulation, and sleep induction. In addition, marijuana has now been shown to have strong ant...

A 33-year-old Malay lady presented to us with 1-month history of globus sensation in the throat. Clinically, she had a 3cmx2cmx1cm sessile soft mass arising from the right tongue base and was treated as hypertrophied lingual tonsil. Biopsy of the mass was done when the patient developed bleeding and was reported as diffuse non-Hodgkin's B-cell lymphoma. Globus sensation is a common complaint in...
