    Notes: Zusammenfassung Es wird gezeigt, dass kristallines Phytohaemagglutanin (PHA) oder Rohextrakt aus PHA enthaltenden Zuckerbohnen (Phaseolus vulgaris) das Wachstum vonRhizobium dadurch beeinflusst, dass die Lagphase der Wachstumskurve verkürzt, die logarithmische Phase aber verlängert wird. Die PHA-Wirkung ist deutlicher bei denRhizobium-Linien, die in den Wurzelknöllchen des Wirts an PHA nicht adaptiert sind.

    Notes: [Auszug] Singh2'3 developed a method for the culture of small free-living amoebae; this enabled him to obtain without any difficulty all stages of nuclear division in nine species of amoebae. The amoebae were grown on thin films of non-nutrient agar on slides. They were then fixed according to normal ...

    Notes: [Auszug] Samples of different grades of muscovite were obtained from the Bihar, Madras and Rajasthan regions?the three main mica-producing states of India. The samples were thoroughly cleaned with benzene (B.D.H.) and stored in a desiccator for 24 h before any optical measurements were undertaken. ...

    Notes: [Auszug] ALTHOUGH the fishes, birds and mammals of Kashmir are well documented, there has been no analysis of the general fauna of Kashmir and the specification of its Palaearctic elements. The fauna has not only been inadequately explored, but the reports of collections are scattered in different ...

    Notes: It was shown that the shape of the scattering pattern is not only related to the shape but also to the face-orientation of the lamellar scattering units, and an actual observation of its characteristic shape depends on the amount and dispersion of their spiral angle. The following results were obtained: (1) For observing a cross-pattern, the critical spiral angles corresponding to minimum and maximum dispersions are 7.5° and 30° respectively, whereas in an actual fiber, coir, the critical angle is about 16.75°. (2) The jute pattern changes from a uniformly narrow to a triangular shape on disorientation and reverts to the former on reorientation. The corresponding changes in ramie are from a triangular to a uniformly wide and then to a uniformly narrow shape. Both native and disoriented cottons give weak, fan-shaped scattering superimposed on a more intense elliptical pattern. The pattern given by reoriented cotton is roughly a narrow streak. Delignified jute gives a somewhat shaving-brush-shaped pattern which changes to a uniformly wide streak on alkali treatment. (3) The extent of scattering decreases on swelling and increases on stretching in jute, ramie, and cotton, but decreases in stretched coir.

    Notes: It was shown that the realization of a straight log I-h2 curve may be a coincidence depending on the relative influence of heterogeneity of distribution and non-independent scattering, and a concave log I-h2 curve can represent a nonhomogeneous system amenable to Shull and Roess's method of analysis. The results indicate: (1) The I-h curve for a jute holo-cellulose film has a maximum, and that for a ramie film an inflexion point, each superimposed on a background of gradually declining intensity, and in either case the singularity is accentuated and shifted to a region of larger angle on alkali-treatment. (2) The log I-h2 plots for untreated, alkali-treated and stretched jute fibers give straight sections in the low-angle, and convex, concave, and straight sections, respectively, in the high-angle region. An interesting feature of the results for ramie is the realization of a straight logarithmic curve on mercerization. The curves for alkali-treated and stretched Fortisan fibers have also each of them two discernible linear parts, indicative of two groups of scatterers. (3) An evaluation of the log I-log h2 curves by Shull and Roess's method leads to figures for the diameters of the scattering elements in ramie comparable to those estimated from the corresponding log I-h2 plots.
