    Notes: In an earlier communication by the authors it was shown that the stack height distribution in a raw carbon black followed an exponential law. Extension of these studies to a heat-treated (2000°C) black showed that the exponential law is still valid when stacking is extensive. The exponential law and the effect of heat-treatment are explained by the existence in blacks of extensive stratification rather than the presence of short stacks of small layers. Evidently heat-treatment results in annealing of the strata to yield uniform layer domains and more ordered stacking. Simple expressions are derived for calculating the profiles of the 00l reflections and the coefficient of the exponent.

    Notes: Abstract During the past two decades, the information explosion has led to a demand for systems of storing and retrieving information in every branch of science and technology. A number of the larger abstracting services are already experimenting with systems covering so great an area that the use of a computer is essential. Since, however, the, field of rheology is relatively small a simple classification and retrieval system is being developed, for use inRheology Abstracts, based upon ordinary 132-hole edge-punched cards. The first half of the system deals with the rheology of fluids and is already in use; it is described in detail in a recent paper (1). The second half, dealing with the rheology of solids, is still being developed. In the fluids system, holes are punched to indicate the following essential features of a paper: general nature; language; type of fluid; rheological properties; type of flow; boundary conditions; important variables and effects; theoretical treatment; type of apparatus; industrial processes involved. As a result two simple hand operations will serve to retrieve, for example, all the papers concerned with turbulent flow of suspensions, or with fracture in polymer melts. Additional operations lead to a narrower, more precise, retrieval. At present the classifying is being done by abstractors. It is hoped that authors will become familiar with the system and will make a practice of classifying their own papers; this would lead to more accurate classification and to the benefit of all concerned.

    Notes: Résumé Deux types de liaisons ont lieu quand des ions d'aluminium réagissent avec les parois cellulaires isolées deStraphylococcus aureus espèce 893. La première interaction a comme résultat la formation d'un complexe stable qui affecte des groupes occupant le mur de la cellule avec un pK a ∼ 5. On suppose l'existence d'un composant de surface constitué par de la protéine combinée à de l'acide teichoique. La deuxième liaison consiste en ions interchangeables dans la couche mobile de cations recouvrant la paroi.

    Description / Table of Contents: Zusammenfassung Bronchialasthma bei Studenten der Universität Minnesota wurde bezüglich der Empfindlichkeit gegen Getreidesamen mit Kontrollgruppen untersucht, um den Einfluss der in der Luft befindlichen Pollen durch nahe gelegene Getreidefelder zu finden. Unter verhältnismässig hohen Konzentrationen wurde beobachtet,dass gegen Getreidesamen empfindliche Studenten doppelt so viele Asthmaanfälle hatten, wie die Kontrollgruppe, die keine signifikante Änderung zeigte. Eine Verbindung von Windrichtung und relativ hohen Staubkonzentrationen mit Asthmaanfällen ergab eine Korrelation von höherer Signifikanz in der sensiblen Gruppe. Weitere Zuordnungen zeigten, dass diese Beziehung nur wenig durch Änderungen von Jahreszeit und Temperatur beeinflusst wird. Es wurde auch beobachtet, dass die Relative Feuchte die Empfindlichkeit gegen Pollen bei entsprechend sensibilisierten Studenten beeinflussen kann. In der Kontrollgruppe zeigten Wetterparameter keine Beziehung zum Asthma.
    Abstract: Resume On a étudié les accès d'asthme bronchial provoqués par les polluants de l'atmosphère provenant d'entreprises travaillant les céréales et situées dans le voisinage du l'Université du Minnesota. Pour ce faire,on s'est servi d'étudiants de la dite Université sensibles aux poussières de céréales d'une part et d'un groupe de contrôle d'autre part. Dans des conditions de poussière relativement forte,on a observé que les étudiants sensibles aux poussières de céréales présentaient une fréquence double d'accès d'asthme alors que le groupe de contrôle n'était pas touché de façon significative. En utilisant une conbinaison des facteurs direction du vent et forte poussière d'une part, accès d'asthme d'autre part,on obtient une corrélation plus significative dans le groupe des gens sensibles.Des combinaisons multiples indiquent que cette corrélation n'est que peu influencée par la saison ou des changements de température. On a aussi remarqué que les conditions d'humidité relative peuvent influencer de façon significative la sensibilité effective aux poussières des étudiants du premier groupe. Quant au groupe de contrôle, on n'a pas trouvé de relation entre les accès d'asthme et les paramètres météorologiques.
    Notes: Abstract Student bronchial asthma at the University of Minnesota was studied in grain sensitive and in control groups to find the influence of air pollutants from nearby grain installations on this problem.Under relatively high dust conditions it was observed that grain sensitive students had a two-fold increase in asthma attacks while the controls showed no significant changes. A combined association of wind direction and relatively high dust conditions with asthma gave a correlation of higher significance in the grain sensitive group. Multiple associations indicated that this relationship is only weakly affected by seasonal and temperature changes. It was also observed that relative humidity conditions may significantly influence the effectiveness of the dust exposure in sensitive students. Weather parameters showed no association with asthma in the control group.
