Ancient Chinese music bells can be traced back to the Shang dynasty (1600–1100 B.C.). In addition to their significance in history and metallurgy, they provide much insight into the design of musical instruments in the early years and continue to make important contribution to acoustics due to their unique acoustical properties and rich physical mechanisms. These music bells differ from carillo...

Introduction There are no established doctrines for treating Bells facial nerve paralysis (Bell's palsy), as there are still controversies in relation to the etiology of the disease. According to available sources 75% of all patients experience minor damage to the myelin sheath, thus usually recovering spontaneously and with no particular treatment.

Infections, immunologic and genetic factors have been suggested to play roles in the aetio-pathogenesis of the disease. Herpes Simplex virus has been demonstrated in the geniculate ganglion by using molecular techniques supported by r...

It is proposed that by using computing analysis software and 3D fabrication techniques, low cost plastic trumpet bells could be produced for different music genres by altering their timbres. These may be attached to the trumpet in a similar manner to that of a tuning bell trumpet. The novel bells are designed to eliminate or enhance particular harmonics to change their brightness by altering th...
