    A syndrome of multiple gastrointestinal atresias with intraluminal calcification (1979)
    Springer
    Pediatric radiology 8 (1979), S. 227-231

    Notes: Abstract An infant with multiple gastrointestinal atresias from the stomach to the rectum is reported and the literature concerning this syndrome is reviewed. The syndrome has been reported, to date, exclusively in infants born to families with a French-Canadian background. The radiological hallmark of this syndrome is extensive calcification of intraluminal content between the areas of atresia which appears as rounded or oval homogeneous radiopacities on abdominal radiographs. Inheritance is thought to be autosomal recessive and the etiology is uncertain. All previously reported cases have died. The significance of biliary gas, seen in postoperative films, is discussed.

    On the time required for reference count management in retention block-structured languages. Part 2 (1978)
    Springer
    International journal of parallel programming 7 (1978), S. 91-119 
    Details
    ISSN: 1573-7640
    Keywords: Block-structured languages ; retention vs. deletion ; contour model ; stack model ; reference counts ; lifetime checks ; time estimates

    Topics: Computer Science
    Notes: Abstract In this paper, two implementations of generalized block-structured languages are presented and compared for time requirements. One implementation, the Lifetime Stack Model, implements the deletion strategy with lifetime checks; the other, the Partial Reference Count Contour Machine, implements the retention strategy. For a large subset of the lifetime well-stacking programs, those that run correctly on the first model, the two models are shown to require nearly the same order of magnitude of time. The use of full label values is shown to have a detrimental effect on the time efficiency of the latter model. Part 1, in Volume 7, Number 1, of this journal, gives a general description of the machines, some of their definitions, and proof of the results. Part 2, in this issue, serves as an appendix to Part 1 and contains most of the formal definitions of the machines.

    Time required for reference count management in retention block-structured languages. Part 1 (1978)

    Notes: Abstract In this paper, two implementations of generalized block-structured languages are presented and their time requirements compared. One implementation, the lifetime stack model (LSM), implements the deletion strategy with lifetime checks; the other, the partial reference count contour machine (PRCCM), implements the retention strategy. For a large subset of the lifetime well-stacking programs, which are precisely those that run correctly on the first model, the two models are shown to require nearly the same order of magnitude of time. The use of full-label values is shown to have a detrimental effect on the time efficiency of the latter model. Part 1, in this issue, gives a general description of the machines and part of their definitions, and proves the results. Part 2, in the next issue, serving as an appendix to Part 1, contains most of the formal definitions of the machines.

    Über Zuordnungsprobleme von 13C-Signalen in den NMR-Spektren von Benzheteroazolen (1979)

    Description / Table of Contents: Carbon-13 chemical shifts of several benzimidazole- and benzoxazole derivatives have been measured. The signals of the homonuclear carbon atoms in unsymmetrical benzoheteroazoles can be assigned with the aid of additivity parameters. The structures of compounds obtained from the reaction of benzimidazoline- and benzoxazoline-2-thione with aryl cyanates were elucidated.
    Notes: Für verschiedene Benzimidazol- und Benzoxazolderivate wurden die chemischen Verschiebungen im 13C-NMR-Spektrum bestimmt. Mit Hilfe von Additivitätsparametern lassen sich die 13C-Signale der Benzokohlenstoffatome in unsymmetrischen Benzheteroazolen bestimmen. Die Struktur der Reaktionsprodukte aus Benzimidazolin- und Benzoxazolin-thion-(2) und Arylcyanaten werden abgeleitet.
