    Notes:
    Experimental evidence is given for transient enhanced diffusion of boron (B) in ion-implanted silicon carbide (SiC). The implanted B is diffusing several μm into the samples when annealed at 1600 and 1700 °C for 10 min, but the in-diffused tails remain unaffected when the annealing times are increased to 30 min at the same temperatures. A lower limit of the effective B diffusivity at 1600 °C is determined to 7×10−12 cm2/s, which is 160 times larger than the equilibrium B diffusivity given in the literature. © 2000 American Institute of Physics.

    Notes:
    Heavily Al-doped 4H–SiC structures have been prepared by vapor phase epitaxy. Subsequent anneals have been carried out in an Ar atmosphere in a rf-heated furnace between 1500 °C and 2000 °C for 0.5 to 3 h. Secondary ion mass spectrometry has been utilized to obtain Al concentration versus depth as well as lateral distributions (ion images). Transmission electron microscopy (TEM) has been employed to study the crystallinity and determine phase composition after heat treatment. A solubility limit of ∼2×1020 Al/cm3 (1900 °C) is extracted. Three-dimensional ion images show that the Al distribution does not remain homogeneous in layers heat treated at 1700 °C or above when the Al concentration exceeds 2×1020 cm−3. Al-containing precipitates are identified by energy-filtered TEM. © 2001 American Institute of Physics.

    [Auszug] Fig. 1 Vaccume expection value of the Higgs field plotted against the expansion parameter of a "standard" universe. In order to illustrate our ideas, we consider a 'proto-type gauge theory' of the Salam-Ward-Weinberg variety (with gauge group SU(2)LEFrU(l)RIGHT) in a curved space with prescribed ...

    Description / Table of Contents:
    Summary One of the most important methods of treating mandibular dysfunction is the provision of occlusal splints. In this article a new appliance for the treatment of this condition is presented for the first time — the so-called “Bioblock”. The most important elements of this appliance are derived from an insight into orthodontics with present day knowledge of mandibular dysfunction, especially displacement of the disc. After a description of the appliance the indications and clinical usage are discussed. Finally, clinical experience with the appliance is described on the basis of three case studies.
    Abstract:
    Résumé L'utilisation d'une gouttière de surélévation occlusale est une des méthodes les plus courantes dans le traitement des dysfonctions mandibulaires. Dans cet article on présente un nouvel appareil: le «Biobloc». Les éléments principaux de l'appareil combinent le point de vue orthodontique avec les connaissances actuelles des troubles fonctionnels mandibulaires, spécialement les déplacement du ménisque articulaire. Après une description de l'appareil, on commente les indications et les applications cliniques et on présente trois exemples pour décrire les résultats cliniques.
    Notes:
    Zusammenfassung Bei der konservativen Behandlung mandibulärer Dysfunktionen ist eine der wesentlichsten zahnärztlichen Maßnahmen die Eingliederung einer okklusalen Schiene. Es wird eine neue Behandlungsapparatur, der sogenannte Bioblock, vorgestellt. Die wesentlichen Konstruktionselemente verbinden kieferorthopädisches Gedankengut mit der heutigen Kenntnis der mandibulären Funktionsstörung, besonders der Diskusverlagerung. Nach der Konstruktionsbeschreibung des Gerätes werden die Indikation und die klinische Handhabung erläutert. Anhand von drei Fallbeispielen wird die klinische Wirkung beschrieben.

    Description / Table of Contents:
    Summary Generally, the occlusal relationship is clinically examined together with models mounted in an articulator. To examine the reproducibility of the two methods, the occlusion of ten individuals was analysed twice in the space of one week. It has been shown that there is a deviation in both methods. On the whole tooth contact in an articulator is moreoften reproducible than in the mouth. Concerning the measurements of slide in centric both methods revealed an equal degree of consistency. When testing individuals, the degree of disturbances are classified byHelkimo's index, and it has been demonstrated that the findings of the clinical analysis often show a higher degree of reproducibility than in the articulator.
    Abstract:
    Résumé En général, on étudie la situation occlusale clinique dans la bouche des patients et sur le modèle dans l'articulateur. Afin de pouvoir étudier la reproductibilité de ces deux méthodes, on a analysé deux fois chacune d'elles chez dix patients dans un intervalle d'au moins une semaine. On a constaté alors, que certaines divergences se présentent dans chacune de ces deux méthodes. Dans l'ensemble, les contacts des dents se laissent plus souvent reproduire dans l'articulateur que dans la bouche. En ce qui concerne la mensuration du glissement centrique, les méthodes se ressemblent. Par contre, si on classe les essais selon le degré des dysocclusions, il semble alors que le résultat d'après l'analyse clinique se laisse reproduire plus souvent que celui dans l'articulateur.
    Notes:
    Zusammenfassung Allgemein werden okklusale Verhältnisse klinisch im Mund des Patienten und am Modell im Artikulator studiert. Um die Repoduzierbarkeit beider Verfahren zu untersuchen, wurde die Okklusion bei zehn Probanden im Mindestabstand von einer Woche jeweils doppelt analysiert. Dabei zeigte sich, daß gewisse Abweichungen bei beiden Methoden auftreten. Insgesamt lassen sich Zahnkontakte im Artikulator häufiger reproduzieren als im Mund. In bezug auf Messungen des zentrischen Gleitens gleichen sich die Verfahren. Werden jedoch die Probanden entsprechend dem okklusalen Störungsgrad klassifiziert, dann scheint sich der Befund nach der klinischen Analyse öfter reproduzieren zu lassen als der im Artikulator ermittelte.
