    Nature 196 (1962), S. 493-493 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] These facts suggest that spores in pycnidia may be less important than has previously been supposed, and tharfc seedlings become infected by parts of the fungi which are not carried superficially on the seed. We have obtained the following evidence in support of this hypothesis: (a) A considerable ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE absorption spectra of polyatomic molecules are usually so complicated that an analysis of their rotational fine structure seems impossible. We have therefore tried if the magnetic rotation spectra which are obtained by putting the absorbing gas in a magnetic field between crossed ...

    Notes: [Auszug] THE Raman spectrum of heavy water has been obtained by 2536 excitation of 8 c.c. of 18 per cent heavy water in a quartz tube 35 cm. in length in contact with a quartz mercury vacuum tube. Two Raman bands were obtained with an intensity ratio of one to four, the new one having a mean wavelength ...

    Notes: [Auszug] A CASE of globular or ball lightning was reported to me at East Hampton last summer, and I had an opportunity of questioning an eye-witness and investigating the premises. This account has value only for comparison with other cases, and I presume someone is making a collection of reports of ...

    Notes: [Auszug] A COMMUNICATION by Venkatesachar and Sibaiya appeared in NATURE for Nov. 30, 1929, in which the opinion was expressed that some of the faint nebulous lines of the mercury arc were in reality Raman lines of mercury excited by the more powerful radiations. This did not seem to me very ...

    Notes: [Auszug] Filtrates from cultures on a synthetic medium containing sucrose, potassium nitrate and mineral salts had little protopectinase activity, little or no pectinesterase activity, were relatively non-toxic to parenchyma cells and caused little vascular browning. Cotton shoots placed in these solutions ...

    Notes: [Auszug] Oysters are able to seal off the perforations made by Urosalpinx ciherea Say. Dr. D. A. Hancock has kindly directed my attention to his observations2. He thinks the falling temperatures might have caused the oyster drills to abandon the attack. Oysters perforated with a hand drill completely sealed ...
