Abstract: The present invention relates to solid forms of (5S)-cyclopropyl-5-[3-[(3S)-4-(3,5-difluorophenyl)-3-methyl-piperazin-1-yl]-3 -oxo-propyl]imidazolidine-2,4-dione and to pharmaceutical preparations comprising them and methods of their manufacture, as well as the use of said solid forms or preparations for the prophylaxis and/or treatment of inflammatory conditions, muscular disease, fibrotic diseases, viral infection, and/or diseases involving degradation of cartilage and/or disruption of cartilage homeostasis, especially osteoarthritis.

Abstract: A sensor apparatus for detecting leakage current in a suspension-type insulator of an electrical power system is disclosed. The sensor apparatus includes a housing having a leakage current sensor contained therein, a door pivotally connected to the housing and adapted to move between an open position where a grounded end fitting of the insulator is received by the sensor apparatus and a closed position, and a clamping mechanism connected to the housing. The leakage current sensor is adapted to detect a leakage current along the insulator. The clamping mechanism is adapted to clamp the sensor apparatus to the grounded end fitting of the insulator.
