    Notes: [Auszug] For water-logged soil the ratio of the conductivities of the two phases is of the order of 7:1, and my formula yields the value 000486 cal. sec.-1 cm.-1 deg. C.-1, which compares with an observed value quoted by Gemant of 0005 cal. sec.-1 cm.-1 deg. C.-1. It would appear probable, then, that my ...

    Notes: [Auszug] I agree with Mr. Makowski when he points out that it is incorrect to assume parallel heat flow in a solid-air composite ; the opening paragraphs of my second communication should make this clear. Dr. de Vries2 has directed attention to a solution by Lord Rayleigh whereby a value for the ...

    Notes: [Auszug] Gemant2 has made a very interesting calculation to find the thermal resistivity of soil. The soil is assumed to consist of uniformly packed spheres each of which touches six neighbouring spheres. The statement is made : "If the spheres were to touch at a geometric point only the resistivity of dry ...

    Notes: [Auszug] SIR,-In the note on January 7 (Nature, 213, 7; 1967), the statement that geochemistry has limited application and is still struggling for recognition is entirely erroneous. The facts of the matter are that since the Second World War geochemical techniques have developed to the point that they are ...

    Notes: [Auszug] Following Selles9, two complexes were crystallised from ethanol or ethanol?water mixtures containing ferric acetate, catechol and piperidine. Conditions of low base yielded deep purple crystals, whereas excess piperidine resulted in burgundy-red crystals. X-ray data for both compounds were recorded ...

    Notes: [Auszug] THE absorption lines seen in the spectra of distant quasars are produced by matter intersecting the line of sight, and show how matter is distributed in the Universe up to the large distances of the quasars themselves. Recent work on quasar absorption lines raises important issues concerning this ...
