INTRODUCTION Milligan-Morgan and Ferguson haemorrhoidectomy has been the gold standard treatment for symptomatic haemorrhoids for many years. However, escisional techniques are associated with a significant morbidity rate. In recent years, diverse techniques have been described in an attempt to decrease these complications. The guided transanal haemorrhoidal dearterialization THD) doppler is on...

To achieve maximum possible power factor and by keeping total harmonic distortion (THD) within the acceptable limit. A new control algorithm of shunt active power filter under distorted grid voltage and unbalanced supply conditions is proposed. A new control algorithm renders the optimal compromise between harmonic free (HF) and unity power factor (UPF) by keeping the total harmonic distortion ...

Pulse contour methods (PCM) for the measurements of cardiac output (CO) are gaining popularity in intensive care settings but their reliability during hemodynamic instability has been questioned. Pressure-recording-analytical-method (PRAM) is a newly developed uncalibrated hemodynamic monitor and its capability in measuring CO during hemodynamic instability is still under investigation. Dobutam...

Repetitive control (RC) scheme presents an attractive solution to achieve excellent steady-state tracking error and low total harmonic distortion (THD) for periodic signals. RC can produce extremely large gains at fundamental and each harmonic frequency of reference signal to achieve all harmonics suppression. However, a DC-AC inverter always has uneven THD distribution, e.g. THD concentrates a...

PURPOSE The purpose of this research was to identify promiscuous T-helper cell determinants (THd) from carcinoembryonic antigen (CEA) to be used to prime T-cell help for cancer therapy. CEA was selected because this antigen is expressed in an important variety of carcinomas. EXPERIMENTAL DESIGN Potential promiscuous THd from CEA were predicted using available computer algorithms. Predicted pe...

The voltage source inverter (VSI) and current voltage source inverter (CSI) are widely used in industrial application. But the traditional VSIs and CSIs have one common problem: can’t boost or buck the voltage come from battery, which make them impossible to be used alone in Hybrid Electric Vehicle (HEV/EV) motor drive application, other issue is the traditional inverter need to add the dead-ba...
