    Notes: Abstract Two types of intravenous nitroglycerin (NTG) perfusion sets were studied using laboratory techniques. A known concentration of NTG was placed in each of these sets, and an evaluation was made as to the dose of NTG actually received by the patient after passage of the NTG solution through the sets. Set number one consisted of a glass container and polyvinyl chloride (PVC) tubing. After passage through this set, there was a rapid and significant decrease in the NTG concentration, i.e. the dose actually received by the patient is less than the dose theoretically administered. Set number two consisted of a polypropylene syringe and polyethylene tubing. After passage through this set, there was no significant change in the NTG concentration, i.e. the patient receives the full theoretical dose.

    Notes: Abstract A new isotope152Tm (T 1/2=5.2±0.6 s) and a new isomeric state in150Ho (T 1/2=88±15 s) were observed with the on-line isotope separator ISOCELE II at Orsay. The decay of152Tm is similar to the one of the high spin state (9+) in150Ho. The new150Ho isomer, probably with a low spin (2 or 3), decays mainly to the 2+ level in150Dy.

    Notes: Abstract Tantalum 164 to 167, Zirconium 82 to 84 and Strontium 78 have been selectively observed at the ISOCELE-2 on-line mass separator (1) in the TaF4 +, ZrF3 + and SrF+ compound form. New isotopes have been identified:165Ta (31.0±1.5 s),164Ta (13.7±0.6 s),82Zr, (32±5 s) and78Sr (2.5±0.3 mn).

    Notes: Abstract By a systematic on-line cesium mass separation fromA=122 toA=132 and subsequent gamma and electron decay spectroscopy at very low energy, new isomers have been precisely identified:122m Cs (T 1/2=0.36±0.02 s),124m Cs (T 1/2=6.3±0.2 s) and130m Cs (T 1/2=3.46±0.06 min). Detailed level schemes are given for both124m Cs and130m Cs. Comparison of excited levels known in the odd-odd nuclei of the same region shows that more experimental informations are needed to propose a clear and realistic picture of the nuclear states structure.

    Description / Table of Contents: Résumé On dérive l'Equation générale des champs de tension d'une pointe de fissure dans un corps anisotrope par une approximation de variable complexe. On a dévini et évalué les facteurs d' intensité de tension qui permettent la représentation concise des conditions pour l'extension d'une fissure, directement des fonctions de tension. On donne quelques solutions de problèmes à valeur limite en forme implicite et on les discute en correspondance avec les solutions analogues pour corps isotropes. On a trouvé qu'une singularité de tension élastique de l'ordre de r −1/2 (où r est la distance radiale depuis le front de la fissure) est toujours présente à la pointe d'une fissure dans un corps rectilinéairement anisotrope. Ce résultat et quelques considérations additionelles des champs de tension de la pointe d' une fissure impliquent la possibilité d'étendre les applications courantes de théories de mécanisme de fracture à la représentation de conditions de fracture de corps anisotropes avec des imperfections en forme de fissures.
    Abstract: Zusammenfassung Die aligemeinen Gleichungen für Spannungsfelder an der Spitze eines Risses in anisotropischen Körpern werden näherungsweise unter Benützung einer komplexen Variabele abgeleitet. Die Spannungsintensitätsfaktoren, die eine kurzgefasste Darstellung der Bedingungen für Rissausbreitung gestatten, werden definiert and unmittelbar aus Spannungsfunktionen bestimmt. Einige individuellen Lösungen von Grenzwert-Problemen werden in geschlossener Form gegeben and bezüglich ihrer analogen Lösungen für isotrope Körper diskutiert. Es ergibt sick, dass eine elastische Spannungssingularität der Ordnung r −1/2 an der Spitze eines Risses in einem Körper mit rectilinearischer Anisotropie immer da ist. (r ist die Radiusabstand von der Rissfront). Dieses Ergebnis, und einige weiteren Betrachtungen der Spannungsfelder an der Rissspitze weisen darauf hin, dass es möglich ist, die geläufigen Methoden der Bruchmechanik für die Darstellung von Bruchbedingungen anisotropischer Körper mit rissartigen Fehlern zu erweitern.
    Notes: Abstract The general equations for crack-tip stress fields in anisotropic bodies are derived making use of a complex variable approach. The stress-intensity-factors, which permit concise representation of the conditions for crack extension, are defined and are evaluated directly from stress functions. Some individual boundary value problem solutions are given in closed form and discussed with reference to their companion solutions for isotropic bodies. It is found that an elastic stress singularity of the order r −1/2 is always present at the crack tip in a body with rectilinear anisotropy (r being the radial distance from the crack front). This result and some additional consideration of the crack-tip stress fields imply that it is possible to extend current fracture mechanics methods to the representation of fracture conditions for anisotropic bodies with cracklike imperfections.
