BACKGROUND Tendinopathy is a common clinical pathology, with mixed treatment results, especially when chronic. In this study, we examine the effects of an ultrasonic debridement modality in a rabbit tendinopathy model. We asked four questions: (1) Was it possible to create and visualize with ultrasound a tendinopathy lesion in a rabbit Achilles tendon? (2) Was it possible to guide a 19-gauge ul...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...

Removal of natural organic matter (NOMs) from actual water is a major challenge in the context worldwide pollution resources. The removal humic acids system combining biochar adsorption and ultrasonic persulfate oxidation was studied this paper. effects addition, concentration initial pH were investigated. A high rate up to 92.5% achieved for combined biochar/ultrasonic/persulfate system, versu...
