    Notes: The paper reports an analysis of the characteristics of those new projects that are killed, that is, terminated before commercialisation. Such projects constitute the majority of new product projects. The authors' aim was to learn from the differences between ‘kills’ and those that are commercialised. The latter may, of course, turn out to be successes or failures.Their sample consisted of 250 new projects of which 123 were ultimately successful, 80 failed and 47 were kills. Two hypotheses were tested: that kills and failures had similar characteristics and that kills differed from successes in the way that failures differed from successes. Four groups of multidimensional project characteristics were measured: product advantage, market attractiveness, competitive situation, and synergy/familiarity.The results showed that neither hypothesis was generally supported, The patterns of characteristics observed were complex but were unravelled through a computer model simulating how managers perform the evaluation process. It showed that the results could be explained on the basis that errors could be made in evaluation. For example, it is difficult to evaluate product advantage. Surprisingly, competitive situation is not a discriminator between successes, failures and kills but managers treat it as if it were. Some characteristics are perceived by managers to be negative although they are, in fact, favourable to project success.The authors claim that these results should lead to better allocation of R&D resources among proposed projects.

    Notes: The research seeks to identify different types or dimensions of new product success and the specific determinants of these different success types. Based on a sample of 125 companies, including 123 new product successes and 80 failures, three independent dimensions of success were found: financial performance, opportunity windows and market share. The determinants of success differ for the three performance dimensions. Managerial implications are discussed.

    Notes: Summary The perilymph density of the sc. tympani, sc. vestibuli and the density of liquor cerebrospinalis in guinea-pigs are measured by determination from mass and volume of the fluid column in a glass capillary tube. For the density of perilymph in sc. vest. a value of ϱ = 1.010 g cm−3, in sc. tymp. a value of ϱ = 1.019 g cm−3, and for liquor a value of ϱ = 1.017 g cm−3 was obtained.

    Description / Table of Contents: Summary In tropical cyclones the air near the ground flows towards the centre, in the middle troposphere it flows outwards. The inflow is governed by the friction on the surface of the sea, the outflow takes place in a field of dynamical moist-indifferent equilibrium. If a typhoon is to be developed, there must first be a dynamical instability. This occurs only under special conditions which cannot easily be met. For the fully developed typhoon a number of laws are stated by means of the principles of momentum and energy which explain the most important phenomena — eye of the storm, zone of the storm, cloud screen, etc. — and allow the calculation of their mutual ratio of magnitude. According to these laws the model of a typhoon is designed.
    Abstract: Résumé Dans les cyclones tropicaux l'air des couches inférieures s'écoule vers le centre, celui de la troposphère moyenne vers l'extérieur. L'apport est dominé par le frottement à la surface de la mer; le flux expulsé a lieu dans un champ d'indifférence pseudolabile au point de vue dynamique. Pour qu'un typhon prenne naissance il faut qu'il y ait au préalable de la labilité dynamique, laquelle n'apparaît que dans des conditions toutes particulières, difficiles à remplir. Dans le cas du typhon bien développé on se sert des théorèmes de l'impulsion et de l'énergie pour établir une série de lois qui permettent d'expliquer les principaux phénomènes (oeil de la tempête, région à vents violents, panache nuageux, etc.) et de calculer leurs ordres de grandeur respectifs. L'auteur propose un modèle de typhon conçu d'après ces lois.
    Notes: Zusammenfassung Bei den tropischen Zyklonen strömt die Luft in den bodennahen Schichten zum Zentrum, in der mittleren Troposphäre wieder nach außen. Der Zustrom wird durch die Reibung an der Meeresoberfläche beherrscht, der Abstrom erfolgt in einem Feld dynamischer Feuchtindifferenz. Wenn ein Taifun neu entstehen soll, muß anfangs eine dynamische Labilität vorhanden sein. Eine solche tritt nur unter ganz speziellen, schwer zu erfüllenden Bedingungen auf. Für den ausgereiften Taifun werden mit Hilfe der Impuls- und Energiesätze eine Reihe Gesetze aufgestellt, die die wichtigsten Erscheinungen — Auge des Sturms, Sturmzone, Wolkenschirm usw. —erklären und ihr gegenseitiges Größenverhältnis zu berechnen gestatten. Nach diesen Gesetzen wird das Modell eines Taifuns entworfen.

    Description / Table of Contents: Zusammenfassung In den als Operationspräparate vorliegenden Rachenmandeln wird nach nassem, saurem Aufachluß photometrisch der Gesamteisengehalt bestimmt und aus diesem durch Abzug des getrennt ermittelten Hämoglobineisens der Gewebseisengehalt in Milligramm-Prozent ermittelt. Zur Beurteilung der Affinität der Rachenmandel zum Eisen und zur Feststellung der notwendigen exogen zuzuführenden Eisenmenge zur Erhöhung der Gewebseisenkonzentration der Rachenmandel warden Gruppen von gleichaltrigen zur Adenotomie vorgesehenen Kindern vor der Operation mit Eisenpräparaten prämediziert. Die kurzzeitige orale Zufuhr von Eisen in Form von Vitaferro-Tropfen und Vitaferro-Dragees ergab keine Auswirkung auf den Gewebseisenspiegel der Rachenmandel. Erst die mehrwöehentliche Behandlung mit Ursoferran 30, i.m. injiziert, ergab einen signifikanten Anstieg der Gewebseisenkonzentration der Rachenmandel.
    Notes: Summary In specimen taken from naso-pharyngeal tonsils removed by surgery the total amount of iron was photometrically evaluated after humid, acid decomposition. From this, the content of tissue iron in mg-% was found by substracting the separately measured haemoglobin iron. In order to judge the affinity of the naso-pharyngeal tonsil towards administered iron and to determine its amount and kind of application, different groups of children of the same age received iron before surgery. Short-time oral application of iron (Vitaferro-drops and Vitaferro-dragées) had no effect on the tissue iron level of the naso-pharyngeal tonsil. Only when Ursoferran-30 had been injected i.m. over several weeks, a significant rise of iron concentration in the tissue of the naso-pharyngeal tonsil was observed.
