Abstract:
... It is well-known that the use of high-speed burring devices with irrigation used in bone surgery produces aerosols, and can toss tissue particles into space. The aim of this study was to assess the spatial vertical contamination in the sterile operation field while using a high-speed cutting device at various locations.A fresh porcine knee was resected for 10 min with a high-speed burring device. ...

Abstract:
... Drip irrigation is an efficient and safe system for reusing wastewater in agriculture. Since emitter clogging is its main limitation, filtration is needed for preventing it. Media filters are commonly used when irrigation water has a high particle load. However, particle removal through a media bed in media filters used in drip irrigation systems has not been widely studied mainly due to experimen ...
