    Notes: [Auszug] ALTHOUGH under difficult conditions, the work at the Netherlands Indies Rubber Research Institute at Buitenzorg (Java) was continued during the Japanese occupation. Since it will be a long time before the accumulated results of the years 1942-45 can be published in detail, some points of general ...

    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE word ‘cellulose’ possesses two connotations: in a technical sense it denotes products obtained by certain processes from vegetable material; in a chemical sense it is commonly used for a linear high-molecular polysaccharide composed solely of glucose residues linked by α 1-4 glucosidic ...

    Control of a Beam of Electrons by an Intersecting Electron Beam (1949)
    [s.l.] : Nature Publishing Group
    Nature 164 (1949), S. 276-277 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IF an electron is sent across a beam of electrons the chance is very small that it will pass a single electron of the beam so closely as to cause any deflexion of consequence from its original path. In a beam that has a current-density of 100 mA./cm.2 and a velocity of 100 ...

    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] SINCE early in 1944, when insecticidal products containing D.D.T. were first put on the market in Denmark, a great proportion of the available D.D.yf has been used for fly control on our farms. The commonest practice has been to spray the inside of cowsheds, pigsties, etc., with a water suspension ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] BAUMBACH1 derived in 1937 the electron densities in the solar corona from a compilation of many measurements of its surface brightness. His values for Ne have proved useful in many investigations of the physical state of the corona and the radio waves emitted by it. ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE widespread occurrence of lumpy skin disease1 in dairy herds of the Cape Peninsula offered suitable material for investigations on the etiology of this disease. Skin nodules or lymph gland excised under local anaesthesia from cases in the early stages of the disease as ...

    Total Emission Noise in Diodes (1947)

    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] C. N. SMYTH1 has shown that the space-charge between anode and cathode in the cut-off region of a diode gives rise to a large input conductance 1/R at ultra-high frequencies. He has also put forward arguments that the space-charge behaves as an additional source of noise at ...

    Notes: [Auszug] IT is a well-known fact that β-carotene is converted by mammals into vitamin A, which is stored in the liver. As vitamin A-acid is biologically active1, it seemed possible that this substance might also be converted into vitamin A. To investigate this question the following ...

    Total Emission Damping in Diodes (1947)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] A FEW months ago, C. N. Smyth1 published preliminary results on a new source of energy loss in space-charge-limited diodes at high frequencies. This energy loss was due to the space-charge between the electrodes, and hence it was called ‘total emission damping’; it is a transit ...

    Notes: [Auszug] Mr. Hawkes and Mr. Driver1 believe that the greatest single factor limiting the yield of Andean varieties under British conditions is the day-length requirement, thereby implying that they are, on the whole, good yielders in suitable conditions. This is not our experience, which ...
