    [s.l.] : Nature Publishing Group
    Nature 198 (1963), S. 780-781 
    Details
    ISSN: 1476-4687

    Notes: [Auszug] We have recently reported a modification of a gas-chromatographic catalytic combusion detector which will allow measurement of the charge released during combustion4. Although the instrument was described as a detector for gas chromatography, there are certain additional aspects of its operation ...

    Notes: [Auszug] IN a recent paper Ertell has shown, at some length, that turbulent motion in the atmosphere reduces the pressure, recorded by a barometer, by ρw′2 dynes/cm.2, where ρ is the density of the air arid w′ is the vertical component of the turbulent velocity. This, ...

    Notes: [Auszug] Results1 from a study of the join calcite-water in the ternary system CaO-CO2-H2O show that calcite begins to melt at a temperature of 740 ° C. at 1,000 bars pressure of water vapour. Only a trace of liquid was developed at this temperature, but the amount increased with increasing water ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The sinus venosus of a frog's heart was excised together with the two vago-sympathetic nerves, cut open and pinned out. When an electrode was inserted into the region where the beat could be observed to start, a typical pacemaker potential2 was seen: the membrane potential decreases slowly ...

    Notes: [Auszug] THE opinion of Sir George Watt in NATURE of February 23 that the report to the Board of Trade of the Empire Cotton Growing Committee is “ingeniously elaborated,” but leaves a “confused impression,” may justify a brief consideration of an allied phase of the subject. Why “the whole history of ...

    Notes: [Auszug] We have presented experimental evidence for the magmatic origin of carbonatites elsewhere4'5. Evidence from the system CaO-CO2-H2O indicates that simplified carbonatite magmas can exist through a wide range of pressure at moderate temperatures. The lowest pressure reached in these experiments was ...

    Notes: [Auszug] THE importance of absorption of gases in reducing the effective concentration during fumigation of various materials for the destruction of insects, is now coming to be recognized, but the full effect of this factor in so-called ‘vacuum fumigation’ does not appear to have been realized. ...

    Notes: [Auszug] IN the problem of locating subterranean anomalies of density, the Eötvös balance measures two quantities, the horizontal gravity gradient and the difference between the principal curvatures of the level surface at the point of observation. In the two-dimensional case these reduce to ...

    Notes: [Auszug] THE extract from a letter to NATURE by R. W. Wood (vol. 121, 1928, p. 501), in Sir Napier Shaw's recently published “Manual of Meteorology”, vol. 3, suggested to me that an observation of the green ray I obtained last spring might be worth recording. Wood remarks that the ray is more ...

    Notes: [Auszug] We report here the capacitation of some sperm by incubation in tissue culture medium alone and a marked increase in the proportion of sperm capacitated when they were incubated in heated bovine follicular fluid devoid of cellular contents. The proportion of sperm capacitated does not seem to be ...
