    Notes: [Auszug] Powell and Eyring have shown that the form of the flow/stress relation observed by us may be described by the addition of a second flow-process. Since this second process is postulated to involve weak bonds, it will be Newtonian on their theory. We would note that the need to assume two ...

    Notes: [Auszug] THE place-exchange theory of plastic flow was originally developed by Becker1, to account for the flow of metals. More recently a somewhat similar theory has teen advanced by Eyring2 to account for flow in polymeric materials. In the latter theory the flow process ...

    Notes: [Auszug] IN collaboration with the Army Malaria Research Unit, we have developed a technique for the quantitative separation by chromatographic means of mepacrine from urine and from blood. The separation is effected on alumina and is made visible by the intense fluorescence emitted, by acridine ...

    Notes: [Auszug] SINCE the time of Gustavson1 and Menschutkin2 it has been known that salts of the AlCl3 type can give stable complex compounds with certain classes of organic compound. We have measured the heats of formation from the salt plus organic liquid of a ...

    Notes: [Auszug] IN 1927, Mr. R. W. Frow, of Wickenby, Lincolnshire, introduced the use of the remedy (since known by his name) as a cure for acarine disease. Mr. Frow informs one of us (A. D. B.) that he has no record of the origin of the formula, but believes that he read of it in a newspaper as a means of ...

    Notes: [Auszug] BHABHA1 has recently shown, on theoretical grounds, that there probably exists a proton having a double charge. Such a particle might be expected to occur in the nuclear explosions produced by cosmic rays, and it has been suggested that the most likely way of detecting it would ...

    Notes: [Auszug] THIS reaction1 has been reinvestigated using a reaction tube containing a second short filament adjacent to the catalyst filament, so that adsorbed films on the latter might be detected by a measurement of their contact potential2. In this way it was shown that the ...

    Notes: [Auszug] THE arc through the sun described by Mr. C. J. P. Cave1 can only, I fear, be identified with the horizontal circle and not with some rare tilted arc. Its identity is clear from the fact that it passed both through the sun and through the parhelia to the 22° halo, which have the ...

    Notes: [Auszug] IT has been found that the urinary excretion of mepacrine has a relation to the excretion of ammonia. The simplest description of this empirical relation is that the mepacrine clearance from the plasma is directly proportional to the rate of excretion of ammonia. This may be expressed thus: ...

    Notes: [Auszug] DURING the course of experiments conducted on the sheep foetus, dyes were injected into the umbilical cord with the object of exploring movements of substances in the cord along non-vascular pathways. The dyes used were a dis-azo dye, ... related to trypan blue, and the same dye linked to ...
