[Psychoneurotische person in der Zahnarztlicher praxis]

Autori žele upozoriti na problem psihoneurotičnih pacijenata, koji se javljaju u sve većem broju tražeći stomatološku zaštitu, kao i na način postupanja s njima. Zalažu se za stručni pristup psihoneurotičnom pacijentu, koji bi bez sumnje olakšao rad stomatologa.The authors wish to emphasize the problem of the growing number of psychoneurotic pationts who are appearying for stomatological treatment and the manner or methods for their acceptance. They are interceding for professional approach towards psychoneurotic patients which would undoubtedly be of great help to dental surgeons.Die Autoren wollen die Problematik der psychoneurotischen Patienten, die in immer grosserer Zahl stomatologischen Schutz suchen, hervorheben und gleichzeitig auf die entsprechende Behandlungsweise hinweisen. Sie treten fur eine fachmannische Zuwendung zum psychoneurotischen Patienten ein, was die Arbeit des Stomatologen ohne Zweifel erleichtert

3D-Hydrogen Analysis of Ferromagnetic Microstructures in Proton Irradiated Graphite

Recently, magnetic order in highly oriented pyrolytic graphite (HOPG) induced by proton broad- and microbeam irradiation was discovered. Theoretical models propose that hydrogen could play a major role in the magnetism mechanism. We analysed the hydrogen distribution of pristine as well as irradiated HOPG samples, which were implanted to micrometer-sized spots as well as extended areas with various doses of 2.25 MeV protons at the Leipzig microprobe LIPSION. For this we used the sensitive 3D hydrogen microscopy system at the Munich microprobe SNAKE. The background hydrogen level in pristine HOPG is determined to be less than 0.3 at-ppm. About 4.8e15 H-atoms/cm^2 are observed in the near-surface region (4 um depth resolution). The depth profiles of the implants show hydrogen located within a confined peak at the end of range, in agreement with SRIM Monte Carlo simulations, and no evidence of diffusion broadening along the c-axis. At sample with microspots, up to 40 at-% of the implanted hydrogen is not detected, providing support for lateral hydrogen diffusion.Comment: accepted for publication in Nucl. Instr. and Met
