    Description / Table of Contents: Résumé Les arthroplasties représentent le tiers des 508 interventions pour métastases des membres réalisées dans notre service pendant 28 ans. Il s'agit le plus souvent d'arthroplasties de hanche et, en comparaison des autres méthodes utilisées auparavant, elles nous ont convaincu de leur supériorité : elles permettent d'enlever la masse tumorale, la douleur disparaît dans environ 3/4 des cas et leur immédiate solidité permet une récupération fonctionnelle rapide et de bonne qualité chez plus de 80 % des patients opérés. Les meilleurs résultats sont obtenus avec la mégaprothèse de hanche qui donne, dans la cadre de cette chirurgie de confort, le plus l'illusion de la guérison totale.
    Notes: Abstract Arthroplasties represent one third of the 508 operations done for bony metastases of the limbs in our department over a 28-year period. They are mainly proximal femoral and in comparison to former methods convince us of their superiority. They remove the tumour, 3 out of 4 patients obtained pain relief and the immediate fixation allows a rapid resumption of good quality function in more than 80% of patients. The best results are obtained with massive total hip prostheses which, within the context of such palliative surgery, gives the best illusion of total cure.

    Description / Table of Contents: Résumé A la lumière de 40 observations d'ostéosynthèses de la diaphyse humérale par voie interne, les auteurs en présentent les difficultés et les complications. Il s'agissait de 30 fractures récentes, de 4 pseudarthroses et de 6 métastases. Sept complications neurologiques sont à mettre au passif de la voie d'abord, ainsi que 2 blessures peropératoires de l'artère humérale. Pour eux les indications de cette voie doivent être restrictives et se limiter aux fractures récentes du tiers inférieur sans paralysie radiale associée.
    Notes: Abstract The authors present the problems and complications of the medial approach to the humeral diaphysis. They treated 30 fresh fractures, 4 nonunions and 6 metastases by this route. There were 7 neurological complications and two injuries of the brachial artery. They conclude that the medial approach to the humeral diaphysis must be reserved for fractures of the lower third without a primary radial palsy.

    Description / Table of Contents: Abstract Изомеризация н-гексана на Pt/NH4NaY описывается следующей реакционной схемой. Величины k1, k2 и kc линейно увеличиваются с увеличением степени обмена аммонийной группы в цеолите, а значительных изменений в селективности не наблюдалось. В течение активации Al частично удаляется из решетки с образованием HAlNaY.
    Notes: Abstract Isomerization of n-hexane over Pt/NH4NaY follows the reaction scheme k1, k2, kc linearly increase with increasing ammonia exchange degree in the zeolite and no significant changes in selectivity occur. During activation Al is partially removed from the lattice framework with the formation of HAlNaY.

    Radiotelemetric assessment of diel cycles in euthermic body temperature and torpor in a free-ranging small mammal inhabiting man-made nest sites (1983)
    Springer

    Topics: Biology
    Notes: Summary Five free-ranging white-footed mice, peromyscus leucopus, known to inhabit man-made nest boxes were captured during winter, surgically-implanted with temperature-sensitive radiotelemeters, and released at the site of capture. The body temperatures of mice which voluntarily inhabited nest boxes were monitored from a remote location with an AM receiver on 17 days. All five mice were able to maintain stable euthermic body temperatures (approximately 35–37°C during the day; 37–39°C at night) during exposure to subfreezing ambient temperatures. Two body temperature profiles of daily torpor were obtained from one animal. On both occasions, the mouse entered torpor approximately 2 hours before sunrise, maintained a minimum body temperature of 18°C, and was fully aroused by 1500h. The influence of thermoregulation (during euthermia and torpor) on energy expenditure and survival in free-ranging mice is discussed.

    Description / Table of Contents: Preparation and Properties of Aluminium Hydroxide. I. Boehmite from Aluminium Nitrate and AmmoniaThe physical-chemical properties of mainly boehmite containing aluminium hydroxide are studied which were made by continuous precipitation from aluminium nitrate solution with ammonia liquor using technical raw materials and test conditions being very similar to those applied in production. The influence of the precipitation conditions (pH value, temperature, concentration and residence time in the precipitation solution) on the composition, structure and texture of the precipitation products is investigated and information about their effect on the filtration behaviour are given.In the case of a continuous precipitation it is possible to obtain phase-pure boehmite being relatively well crystallised. The crystallinity and dispersity of the precipitated hydroxide determine their filterability and the cavity structure.
    Notes: Es werden die physikalisch-chemischen Eigenschaften von vorwiegend Böhmit enthaltenden Aluminiumaquoxiden untersucht, die durch kontinuierliches Fällen aus Aluminiumnitratlösung mit Ammoniakwasser unter Verwendung technischer Rohstoffe und bei produktionsnaher Versuchsführung hergestellt wurden. Der Einfluß der Fällbedingungen (pH-Wert, Temperatur, Konzentration und Verweilzeit in der Fällsuspension) auf die chemische Zusammensetzung, Struktur und Textur der Fällprodukte wird erforscht und über deren Auswirkung auf das Filtrationsverhalten berichtet. Im Unterschied zur diskontinuierlichen Arbeitsweise kann bei kontinuierlichem Fällen bereits nach kurzen Verweilzeiten phasenreiner, relativ gut kristalliner Böhmit erhalten werden, dessen Filtrierbarkeit mit den morphologischen Eigenschaften der Niederschläge variiert.

    Description / Table of Contents: Studies on Oxide Catalysts. XXX. Characterization of the Me2+ Localization in Zeolites CaNaY, MgNaY, and CaMgNaYData for exchange of the cations Ca2+, Mg2+, as well as Ca2+ and Mg2+ into the zeolite NaY have been determined. From this it was concluded on the localization of Me2+ cations in hydrated samples.The adsorption of ammonia in the temperature region of 420 to 670 K, the determination of the heats of immersion in water and nitromethane and the Me2+ —CO-interaction indicated by IR spectroscopy yielded informations on the localization of cations in dehydrated samples.The results show that cations Ca2+ more selectively than cations Mg2+ occupy positions in the small cages. In the case of the competitive cation exchange this fact causes a site directed distribution of cations in zeolite cages.
    Notes: Unter Verwendung von Ioneaustauschdaten für den Eintausch von Mg2+-, Ca2+- sowie Mg2+- und Ca2+-Ionen in NaY-Zeolithe werden Aussagen zur Lokalisierung der Kationen im hydratisierten Zustand der Proben getroffen.Die Ammoniakadsorption im Bereich von 420 bis 670 K, die Ermittlung der Immersionswärmen in Wasser und Nitromethan und die IR-spektroskopisch indizierte Me2+ -Co-Wechselwirkung liefern Informationen über die Kationenlokalisierung in den dehydratisierten Proben.Die Ergebnisse zeigen, daß Ca2+-Kationen selektiver als Mg2+-Kationen Positionen des kleinen Hohlraumsystems besetzen. Beim konkurrierenden Ionenaustausch wirkt sich die selektive Besetzung von Positionen des kleinen Hohlraumsystems mit Ca2+-Kationen dirigierend auf die Verteilung der Kationen im Zeolith aus.
