    Notes: [Auszug] We have recently explored the potentialities inherent in the determination of this relationship by photoelectric methods. The method eonsists essentially in measuring the photo-current produced on illumination of a freshly formed metallic mirror with ultra-violet light of suitable wave-lengths ...

    Notes: [Auszug] MORE than seventy years ago, Balfour Stewart1, and later Schuster2, realized that the small regular daily oscillations of the compass needle were probably produced by electric currents in the upper atmosphere. The latter put forward a detailed quantitative theory, the 'dynamo theory', which ...

    Notes: [Auszug] FRANZ ANDREAS (FRANCIS) BAUER was born in Feldsburg, Austria, in 1758. He settled in England some thirty years later as a result of a meeting with Sir Joseph Banks, who gave him em-ployment as an artist at the Royal Gardens in Kew, where his title eventually included that of 'Botanical Painter to ...

    Notes: [Auszug] The ending in '-in' suggests strongly that the name applies to a single chemical substance or to a group of closely allied substances (for example, adrenalin, mucin, chitin). Our objection is twofold. First, it may be argued that the time has gone past when it was desirable to give to organic ...

    Notes: [Auszug] We now report further evidence relating to these problems. Wrinkled pea, smooth pea, normal maize, waxy maize, and tobacco leaf starches were examined in polarized light. Wrinkled pea starch contains 98 per cent amylose and 2 per cent amylopectin9; smooth pea contains amylose and amylopectin in the ...

    Notes: [Auszug] This is important, because it had already been established (in 1940) by Warmke and Blakeslee' that a tetraploid race, once formed, could spread without loss of dioecism even though such a race had not then been discovered. Nevertheless, Baker6"' has shown that a number of plants representing the ...

    Hydrolysis of Casein with Sulphur Dioxide (1952)

    Notes: [Auszug] In the course of an investigation on the use of various acids for the hydrolysis of casein, we have carried out preliminary experiments with liquid sulphur dioxide. It seemed possible that the reducing properties of this material might prevent destruction of tryptophane. It was also hoped that the ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Two main methods have been developed for their synthesis. In the first, a deoxybenzoin, for example (II), is converted into a 2-styryk'sonavone, either by direct cinnamoylation1 or by acetylation to a 2-methyk'sonavone followed by the condensation of the reactive methyl group with benzaldehyde2, ...

    Simplified Embedding of Biological Material for Thin Sectioning (1952)

    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The present technique evolved from a belief that it should be possible to simplify the embedding if the use of a solvent for the embedding material could be dispensed with. It is well known that the melting point and hardness of a beeswax-rosin mixture is a function of the beeswax-rosin ratio. A ...
