Reliability of gas turbine power plant is related to the blade normal operation. In this paper, a new on-line condition monitoring method has been presented to evaluate two important factors affecting the turbine blades that are the tip clearance and tip deformation. A K band’s microwave sensor has been simulated and optimized in CST Microwave Studio software. Scattering parameters of the near...

hepatitis c virus (hcv) has chronically infected million peoples worldwide. spontaneous viral clearance occurs in 25% of affected patients.  the standard regimen to treat hcv infection is the combination of pegylated interferon and ribavirin.

Railway tunnel clearance is directly related to the safe operation of trains and upgrading of freight capacity. As more and more railway are put into operation and the operation is continuously becoming faster, the railway tunnel clearance inspection should be more precise and efficient. In view of the problems existing in traditional tunnel clearance inspection methods, such as low density, sl...

A physiologically based pharmacokinetic (PBPK) modeling approach was used to assess the prediction accuracy of propofol hepatic and extrahepatic metabolic clearance and to address previously reported underprediction of in vivo clearance based on static in vitro–in vivo extrapolation methods. The predictive capacity of propofol intrinsic clearance data (CLint) obtained in human hepatocytes and l...

Nasal and tracheobronchial mucociliary clearance have been compared in 10 healthy subjects. Nasal clearance was measured by monitoring the rate of removal of 2 microns diameter Teflon particles, labelled with 99mTc, which had been placed in the anterior part of the nose. Tracheobronchial clearance was measured with an objective radioaerosol technique, 5 microns diameter polystyrene particles be...

Small rotor clearance is today a vital prerequisite for an efficient screw compressor. The clearance will increase compressor leakage, and thereby minimize both the volumetric and adiabatic efficiency. But, the inter-lobe clearance is necessary for compressor running. Therefore, a mathematical apparatus to quantify the inter-lobe clearance is precondition of taking a reasonable inter-lobe clear...

This study was performed to clarify alterations in lamotrigine (LTG) clearance during pregnancy and childbirth. Fourteen women on LTG monotherapy had LTG concentration samples obtained before conception and monthly. LTG apparent clearance, weight-adjusted relative clearance, and percentages of baseline clearance significantly differed between preconception baseline and each trimester and betwee...

Mucociliary clearance was measured in four patients with chronic autonomic failure and normal ventilatory function using a method of scanning the clearance of inhaled polystyrene particles tagged with 99mTc. Previous surgical and experimental evidence has suggested that autonomic denervation might be expected to impair clearance. However, the four patients in this study showed no significant di...
