Objective Revision ACL reconstruction is becoming more frequent because of a 10% rate of re-ruptures and insufficiencies. Currently, computed tomography (CT) represents the gold standard in detecting and measuring the tunnels of the initial ACL reconstruction. The purpose of this study was to compare measurement results of CT and thin-sliced MRI sequences, which were modified to a high soft tissue-bone...
During recent years, technological innovations, especially increasing demand on green technologies, resulted in manifold applications using rare earths which lead to a steep increase in their demand. The high demand and the expected supply shortages, additionally triggered by Chinese export restrictions, lead to a significant increase in rare earth prices. This is also triggered by the fact that currently...
Especially in the Mediterranean region water is a scarce resource and new approaches to water supply need to be focused. An important contribution can be realised by greywater recycling in decentralised structures. This paper describes the results of a technical feasibility study to treat greywater with membrane technology in view of its reuse for applications which do not require potable water quality...
