Energy storage both electrical and thermal is a rapidly emerging field of interest toward the development of more sustainable energy systems. The inherent inefficiencies associate with electrical storage can be partially overcome when thermal storage that collects and storage the waste thermal energy for alternative uses is integrated. Consequently, thermal energy storage systems are an enabling technology...
Aim: To investigate and compare two specific methods of Ilizarov wire tensioning and hold.Method: This study utilised the vertical Hounsfield test machine H25KS, a stress/strain device with a load-cell linked to a computer program. Firstly, the department's present mechanical tensioners were assessed. Secondly, the method of twisting the three designs of wire holding bolts to achieve wire tension,...
The purpose of this study was to establish the optimal fixation of tensioned wires to the frame construct in the Ilizarov system. The usual torque to which the fixation bolts were tightened in clinical practice was established by serial testing of orthopaedic surgeons' work in our unit.The force required to produce wire slippage from the different types of wire fixation bolts, tightened to a predetermined...
A study of 20 doctors in their first or second postgraduate year highlighted deficiencies in their knowledge of the nerve supply of the hand and forearm. The children’s game rock–paper–scissors (Figs. 1–3Fig. 1Rock: the pronated fist, median nerve.Fig. 2(a, b) Paper: the extended wrist and hand, radial nerve.Fig. 3Scissors: the ulnar nerve.) can be used as a simple aide-memoir for the nerve supply...
