    Description / Table of Contents: Zusammenfassung. Bei der total extraperitonealen endoskopischen Präparation der Leistenhernie (TEP) wird durch Aufblasen eines Ballons im supravesicalen Raum eine künstliche präperitoneale Höhle geschaffen. In einer Studie in vivo und an – gemäß den von Thiel 1992 entwickelten Techniken – spezialfixierten Leichnamen wurde untersucht, in welchem Lageverhältnis zum Ballon sich die Fascia transversalis befindet und was mit ihr beim Aufblasen des Ballons geschieht. In allen analysierten Fällen erwies sich die Fascie medial als adhärent am Peritoneum, lateral an der vorderen Bauchwand, so daß wir systematisch ein Zerreißen der Fascia transversalis längs der Plica umbilicalis lateralis, also der A. epigastrica inferior, beobachten konnten. Bei der TEP kann die Fascie allenfalls lateral der Arterie als Verstärkung der Hinterwand des Leistenkanals oder als Widerlager zum Fixieren vom Fremdmaterial (Netz) genutzt werden.
    Notes: Summary. During total extraperitoneal dissection of inguinal hernias, an artificial preperitoneal cavity is created in the supravesical space by using a balloon dissector. During the operative procedure in vivo and while examining cadavers specially fixated according to the method developed by Thiel in 1992, we investigated the position relative to the balloon the transversalis fascia could be found in and what happened to it during inflation of the balloon. In all cases, the fascia medial to the inferior epigastric arteries was adjacent to the peritoneum and lateral to the abdominal wall. We observed systematic tearing of the fascia along the lateral umbilical plica (inferior epigastric artery). These results suggested that the transversalis fascia could be used only laterally for reinforcement of the dorsal wall of the inguinal canal and/or the support of a mesh used to cover the inguinal floor.

    Notes: Abstract New methods for the detection of ECG and EOG artefacts in the EEG are introduced, which can also be used for the evaluation of the quality of the elimination procedure. These algorithms are based on the estimation of the power or coherence spectrum by means of FFT. The advantage of this method is that the EEG spectrum is monitored by the test algorithm. The spectrum will be plotted if no influence of the ECG and EOG can be found. On the other hand, if artefacts are detected the correction of the EEG time series will be carried out and the spectrum of the corrected EEG time series will be plotted after repeated monitoring by the test algorithm.

    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.
