PURPOSE The purpose of this study was to evaluate the level of contaminants on, as well as the quality of, reprocessed shaver blades. METHODS We assessed 7 new shaver blades and 27 shaver blades that had been reprocessed with mechanical cleaning, functional testing, and sterilization with ethylene oxide. A spectrophotometer measured the amount of nucleic acid and protein. The blade quality wa...

one of the most problems that limits use of turbomachines at high speed applications is cavitation. cavitation can damage casing and blades of turbopump, also can make unstability in system. inducer that was installed in front of main impeller can improve cavitation characteristic of system and increase static pressure just before entrance of centrifugal pump. specially in fuel feed system of l...

The effect of the geometrical parameter of blades on heat transfer co-efficient were experimentally studied for agitated vessels using coal slurry in coal gasification. The intensity of hear transfer during mixing of fluids depends on the type of the stirrer, the design of the vessel and conditions of the process. The type and size of the stirrer, as well as its location in the vessel, also aff...

Out of the total wind turbine failure events, blade damage accounts for a substantial part, with some studies estimating it at around 23%. Current operation and maintenance (O&M) practices typically make use of corrective type maintenance as the basic approach, implying high costs for repair and replacement activities as well as large revenue losses, mainly in the case of offshore wind farms. T...

Introduction: Traditionally, DTI data is acquired with EPI because of its short imaging time. However, EPI-based DTI suffers from eddy-current and magnetic field inhomogeneity-related artifacts. Turboprop is characterized by low sensitivity to eddy-current and B0 effects, and is gaining popularity in DTI studies of the brain. In EPI-based DTI, it has been shown that, measuring diffusion weighte...
