AIM Burr-hole craniostomy is the most efficient and safe choice for surgical drainage of chronic subdural hematoma (CSDH). Although the twist-drill drainage is also relatively safe and time-saving, it carries the risk of inadequate drainage, brain penetration and hematoma formation. Our modified technique helps in avoiding bleeding and brain penetration. MATERIAL AND METHODS T...

Abstract With the continuous expansion of scale power grid in China, traditional line inspection method has been difficult to meet requirements future system, research and application robot become inevitable.Line instead manual inspection, not only can avoid unnecessary dangers, but also complete insulation repair work, efficiency is high [1-2]. This project by 10 kv overhead insulated package ...

PURPOSE Metallic implants may cause serious tissue heating during magnetic resonance (MR) imaging. This heating occurs due to the induced currents caused by the radio-frequency (RF) field. Much work has been done to date to understand the relationship between the RF field and the induced currents. Most of these studies, however, were based purely on experimental or numerical methods. This study...

Power electronic modules are widely used in various industries such as aerospace, railway, automotive, alternative energy generation and distribution application for conversion and control of electrical power. An insulated gate bipolar transistor (IGBT) is a power module that is wildly used in various electric products such as power supplies, DC/DC converters and uninterruptible power systems. ...

To enable stating a final common sensor design of purely textile, measuring wound pads for the monitoring surgically provided wounds with regard to tissue temperature, moisture release and stretching (as indicators most prominent healing disruptions bacterial inflammation, bleeding/seroma discharge, haematoma/seroma formation), aim this investigation was identify quantify possible variables pra...

Due to the constant changes of environment and load, insulated-gate bipolar transistor (IGBT) module is subjected a large amount junction temperature (Tj) fluctuations, which often leads damage bond wires. The monitoring parameters IGBTs are coupled with Tj, increases difficulty IGBTs’ health status online. In this paper, based on collector current (Ic) collector-emitter on-state voltage (Vce_o...

UNLABELLED During mechanical preparation of the post space, the root canal filling may be twisted or vibrated, depending on several factors associated with the preparation technique and quality of filling. OBJECTIVE The purpose of this study was to investigate the effect of immediate and delayed post space preparation on the integrity of the apical seal. MATERIAL AND METHODS Sixty-four extr...
