    Description / Table of Contents: Zusammenfassung Ein für die Routine brauchbares Laserskalpell konnte bisher aus technischen Gründen noch nicht entwickelt werden. Die Koagulation von Schnittflächen parenchymatöser Organe und die Verschorfung blutender Ulcers zeigte im Tierexperiment gute Ergebnisse. Es wird die Möglichkeit der Vaporisation von Melanomen, Verödung von Hämangiomen und Varicen sowie der Verschweißung von Knochen angesprochen. Außerdem wird über die räumliche Darstellung von Röntgenbildern und die Überwachung von Stoffwechselvorgiingen in der Intensivpflege durch die Laser-Absorptions-Spektroskopie berichtet.
    Notes: Summary For technical reasons it has hitherto not been possible to develop a laser scalpel suitable for routine surgery. In animal experiments good results have been obtained with the coagulation of incisions in parenchymatous organs and in the searing of ulcers. The possibilities of vapourizing melanomas, coagulating haemangiomas and varicose veins, and fusing bones are touched on. In addition, the three-dimensional projection of X-ray pictures and the application of laser absorption spectroscopy to the monitoring of metabolic processes in intensive care are reported.

    Notes: Abstract We consider the spin-averaged nucleon forward Compton scattering amplitude in heavy baryon chiral perturbation theory including all terms to order $$\mathcal{O}(q^4 )$$ . The chiral prediction for the spin-averaged forward Compton scattering amplitude is in good agreement with the data for photon energiesω≦110 MeV. We also evaluate the nucleon electric and magnetic Compton polarizabilities to this order and discuss the uncertainties of the various counter terms entering the chiral expansion of these quantities.
