Die Endotrachealintubation hat sehr haufig eine Tubusfehlposition zur Folge. Daher ist eine rontgenologische Positionskontrolle des Endotrachealtubus nach jeder Intubation unbedingt notwendig. Jede Rotation und Flexion des Kopfes fuhrt zu einer Verschiebung des Tubus bis zu maximal 1,5 cm.
Background light in potential sites for the ANTARES undersea neutrino telescope
2000
The ANTARES collaboration has performed a series of {\em in situ} measurements to study the background light for a planned undersea neutrino telescope. Such background can be caused by $^{40}$K decays or by biological activity. We report on measurements at two sites in the Mediterranean Sea at depths of 2400~m and 2700~m, respectively. Three photomultiplier tubes were used to measure single counting rates and coincidence rates for pairs of tubes at various distances. The background rate is seen to consist of three components: a constant rate due to $^{40}$K decays, a continuum rate that varies on a time scale of several hours simultaneously over distances up to at least 40~m, and random bur…
