    Notes: The practical importance of tungsten monocarbide prompted an investigation into its wear mechanism. Initial studies on ball-milled tungsten carbide powders revealed considerable plastic deformation, coupled with a reduction in crystallite size. Deformation stacking faults, involving slip on the basal plane, were observed. The work was extended to sintered blocks, tool tips and single crystals. Studies on the worn surfaces of these revealed plastic deformation that extended to a depth of a few microns below the surface. The plastic deformation is an important factor in the wear of tungsten carbide.

    Description / Table of Contents: Résumé On décrit une nouvelle méthode à calculer la pureté des substances organiques non polymères à l'aide de la courbe enregistrée sur un “Differential-Scanning Calorimètre”Perkin-Elmer. Au lieu d'utiliser seulement la partie initiale du pic, on se sert du tracé complet. On attribue une valeur numérique définie à la perte d'énergie, précédemment déterminé e par approximations successives. Un seul enregistrement sur le DSC permet d'obtenir des valeurs significatives de la pureté, avec des échantillons à 95–99.9 %. On montre que cette nouvelle méthode fournit des résultats plus exacts et moins ambigus que celle des fabricants
    Abstract: Zusammenfassung Es wird über eine neue Methode zur Ermittlung der Reinheit von organischen, nicht-polymeren Stoffen mit Hilfe einer durch ein Differential-Scanning Calorimeter Perkin-Elmer gezeichneten Kurve berichtet. Die Methode beruht auf der Verwendung der vollen Kurve und gibt für den Energieverlust definitive numerische Werte. Verläßliche Reinheitswerte von Proben von 95 bis zu 99.9 % Reinheit können durch eine einzige Kurve erhalten werden. Die neue Methode gibt sicherere und eindeutigere Ergebnisse als die von den Geräterzeugern vorgeschlagene.
    Notes: Abstract This paper presents a new method for the calculation of the purity of organic, non-polymeric samples using the recorder trace from a Differential Scanning Calorimeter (DSC), Perkin-Elmer Corp. The entire DSC recorder trace is employed rather than only the initial portion of the curve. The previous trial and error choice of energy lost by the DSC trace has been replaced by a definite numerical value. Meaningful purity values have been obtained from a single DSC trace on samples of from 95 to 99.9% purity. This new method has been demonstrated to provide more accurate and less ambiguous results than the manufacturer's procedure.

    Notes: Summary Morphological aspects of centriole replication as displayed in tracheal epithelial cells of 15 to 19-day-old chick embryos during ciliogenesis were examined by electron microscopy. It was found that centriole replication and development take place in a finely fibrous region around the two mature centrioles of the diplosome. Procentrioles in early stages of development are observed in clusters. The core of each cluster is occupied by one or more cylindrical structures which gradually disappear as the procentrioles mature. Some of the procentriolar clusters are attached directly to the walls of the diplosomal centrioles by the cylindrical cores. This observation suggests that all of the clusters may form initially in close association with the diplosomal centrioles. The earliest recognizable procentrioles are short, cylindrical structures that have no microtubules. Later microtubules appear, first as singlets, then doublets and finally as triplets. The singlet becomes the innermost microtubule of the triplet. Following the assembly of the nine triplets, the procentrioles separate from the clusters, elongate to their mature length and acquire rootlets, ciliary vesicles and cilia. The observation that all the procentrioles in each cell are in the same stage of development indicates that all the centrioles or presumptive basal bodies required by this cell are produced at the same time.
