We present a 55-year-old male who presented with painful non-healing ulcers on the lower lip and scrotum associated with productive cough, fever, anorexia and dysuria. Erythrocyte sedimentation rate was raised, sputum was positive for acid fast bacilli. Chest X-ray was suggestive of pulmonary tuberculosis. A prostate biopsy was also suggestive of(More)

This paper presents a boost converter along with a flyback converter. The Zero Voltage Switching (ZVS) technique is used to achieve soft switching. A bidirectional boost converter is connected with an output module as a Parallel Input Serial Output configuration. The flyback converter with Voltage Doubler Rectifier (VDR) acts as an output module. This(More)
The Dynamic Voltage Restorer (DVR) provides an advanced and economical solution for both voltage sag and swell problems. The voltage-restoration process involves real-power injection into the distribution system. The Interline DVR (IDVR) proposed in this paper provides a way to compensate the voltage deviation caused in a feeder. The IDVR consists of(More)
Residual metal impurities were exploited as reactants in the functionalization of the surface of single-walled carbon nanotubes (SWCNT) with nickel hexacyanoferrate (NiHCF) by simple electrochemical cycling in ferricyanide solutions. This facile in situ electrochemical modification process provides intimate contact between NiHCF and SWCNTs that improves the(More)
