let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

Distal biceps ruptures are uncommon injuries that comprise approximately 3% of all biceps pathology. This injury is most commonly seen in 40- to 60-year-old men, and the mechanism of injury involves a forceful extension movement to a flexed elbow. Without surgical intervention, patients are left with measurable weakness in elbow flexion and supination as well as a cosmetic deformity that often ...

A transverse skin incision 2 cm distal to the elbow skin crease was made and the lateral antebrachial cutaneous nerve was protected. In acute cases the the retracted biceps tendon and the tendon tract were readily identified. With the elbow in full extension and supination, the radial tuberosity was exposed. A cortical window to accommodate the tendon was made with a burr. A drill was advanced ...
