• 2013:31 Aesthetic ultrasound devices – current state of knowledge and suggested measurement set-up for characterization of exposure

  This report concerns the ultrasound devices used for the aesthetic purposes of body contouring and fat reduction (ablation of adipose tissue). Such devices have recently become more frequent on the Swedish ... Swedish market. These ultrasound devices are currently not medically regulated in Sweden and little is known about their safety and potentially harmful exposure when using them. This report aims to provide...

• 2013:01 Validation of Weld Residual Stress Modeling in the NRC International Round Robin Study

  Weld residual stresses (WRS) have a large influence on the behavior of cracks growing under normal operation loads and on the leakage flow from a through-wall crack. Accurate prediction on weld residual ... when cracks in weld joints are detected. During the latest years, there has been a strong development in both analytical procedures to numerically determine WRS and experimental measurements of WRS. The USNRC...

• 2013:07 Corrosion of copper in distilled water without molecular oxygen and the detection of produced hydrogen

  In this report, results are presented for copper which has been exposed to pure anoxic water in the temperature interval of 21 °C to 55 °C up to a total of 19 000 hours. Characterisations of copper surfaces ... been performed ex-situ, meaning after termination of the experiment and exposing the specimen to normal atmospheric environment. Ideally characterisation of surfaces should have been performed with the...
