Injuries to the acromioclavicular (AC) joint are common, particularly in the young and active population. Approximately 9% of all shoulder girdle injuries involve the AC joint, and AC joint dislocations represent approximately 8% of all joint dislocations throughout the body. AC joint injuries are graded as type I through type VI according to the Rockwood classification. Type I and II injuries ...

High-voltage insulators are one of the devices widely used in power systems, and their pros cons directly related to safe stable operation system. The large-tonnage UHV insulator AC withstand voltage detection method is restricted by conditions at engineering site, efficiency low difficult implement. research on detecting zero-value using high-voltage pulses development portable great significa...

Mammalian heart has been reported to express AC isozymes (types V and VI) that are inhibited by < microM [Ca2+]; avian heart has been reported to express adenylyl cyclase activity that is inhibited by < microM [Ca2]. We have used reverse transcription polymerase chain reaction (RT-PCR) to determine that type V and VI AC mRNAs are present in freshly isolated ventricular myocytes. Subsequent RNas...

In high speed electrical machines, one of the main challenges that can be faced is frequency losses in machine windings due to both skin and proximity effects. This paper studies effect using different types magnet wires on AC winding electric machines. Using finite element modelling (FEM), conductors are subdivided into multiple strands calculate each conductor layer. Aiming at loss minimizati...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...
