The specific contribution of the proximal and distal nerve stumps across an 8 mm gap within silicone chamber regeneration models was studied. For this, proximal and distal (Group A), distal and distal (Group B) and proximal and proximal (Group C) nerve stumps were placed in opposite ends of silicone chambers. In all the groups, a tissue cable forms between the nerve stumps, demonstrating that, ...

High-voltage silicone rubber composite insulators are widely used for outdoor insulation in power transmission lines. Silicone rubber, which is as a housing material, gradually degrades with long-term use the field. Therefore, to accurately determine lifetime of insulators, it essential evaluate this degradation. This paper describes results depth profiling, shows change chemical composition ca...
