    Notes: Abstract It can be shown that the sequence of spontaneous movements in the active sleep of healthy neonates can be described as a Poisson process. This statistical model is the basis of the modelling of movement-related heart-rate reactions (MRHR) as a secondary process. Modelling these processes gives essential information about possible diagnostic parameters such as the mean frequency of classified movements in active sleep (AS), and characteristics of the course of MRHR. Optimisation of the reliability of interpreting power spectral parameters, analysis of longterm rhythms and designation of the physiological trends of neonatal heart rates can be attained if the results of time series analysis are compared with fitted simulations. Modifications and new techniques of data acquisition and processing are created by means of the computer model.

    Description / Table of Contents: Water cooling of hollow steel sections in buildings in case of fireSupporting hollow steel sections in building constructions can be water cooled. In case of fire, the water cooling must guarantee the supporting function of the steel sections for a definite period of time. Possible corrosion reactions are discussed for the normal service as well as for the case of fire. The parameters of interest are outlined and explained in detail with respect to testing. Cases of application are presented, and the corrosion resistance of the systems is described.
    Notes: Tragende Stahlkonstruktionen für Bauten können aus Hohlprofilen mit Wasserkühlung hergestellt werden. Während eines möglichen Brandfalles muß die Wasserkühlung eine möglichst langdauernde Funktion der tragenden Stahlkonstruktion gewährleisten. Für den Betriebs-und Brandfall werden mögliche Korrosionsreaktionen diskutiert und gezeigt, welche Punkte im einzelnen zu beachten und zu prüfen sind. Anwendungsbeispiele werden dargestellt und die Korrosionsbeständigkeit der Systeme erläutert.
