ABSTRACT
The ITER bolometer diagnostic is planned to have 550 lines of sight (LOS) distributed all over the vessel. 240 channels are provided by cameras mounted in two upper ports and in one equatorial port. This paper describes the current status of the system level design of the port cameras and the solutions proposed on how to implement all required camera components while meeting a multitude of competing requirements. Sensor holders, support structures, and different apertures depending on the camera type (pinhole or collimator), cable connectors, ceramic track plates, and many mineral insulated cables have to be integrated within a restricted space envelope to guarantee functionality. The design of the internal electrical interfaces and the external mechanical mountings will be described as well. Using the example of an upper port camera with 60 LOS, the assembly of the camera components is explained and two currently discussed architecture options for the remote handling maintenance scheme in the hot cell are compared.
ABSTRACT
UNLABELLED: The data of 596 electro-hydrothermal coagulations in nonvariceal acute gastrointestinal bleeding were retrospectively evaluated and the results were compared to a previous period in which the endoscopic hemostasis was not regularly applied. Initial hemostasis was achieved in 96.1%, the rebleeding rate was 20.5%, perforation occurred in 0.5%. Comparing the two period the need of urgent surgery decreased from 9.2% to 3.4% (p < 0.05) and the mortality from 25.4% to 12% (p < 0.01). CONCLUSION: The electro-hydro-thermal coagulation is a safe and effective method in the treatment of nonvariceal gastrointestinal bleeding.

The authors present the use of ROMICRO set (originally developed for mini laparotomy) for thoracic and lumbar sympathectomy. They review 3 thoracic and 2 lumbar sympathectomy operations that had good effects and uneventful recoveries. The advantage of the method is that no special instruments are needed and it can be done as a conventional operation.
