    Notes: [Auszug] A LITTLE more than thirty years ago, Irving Langmuir and Harold Mott-Smith carried out an important series of investigations on low-pressure mercury discharges1, on which they based their theory of the positive column in electro-positive gases. They distinguished two regions in the discharge : the ...

    Notes: [Auszug] Acrylonitrile was polymerized photochemically in a tube of J in. diameter with di-iert.-butyl peroxide (10 per cent v/v) as catalyst. The rate was 7 x 10~3 mol.lit.-1 sec.-1. After 20 per cent conversion the unchanged monomer and catalyst were distilled off in vacuum and the tube sealed. The ...

    Notes: [Auszug] In 1948, Felix and Banker made an attempt to evolve a typing scheme of Salm. paratyphi A similar to that which was first devised by Craigie and Yen2 for the typing of Salm. typhi. The bacteriophage chosen for this purpose had been isolated in 1943 by the late Prof. R. G. Dhayagude from a sample of ...

    Notes: [Auszug] A tentative explanation of these features can be offered if it is assumed that the sea waves act as diffraction gratings. It is known8 that, under a given wind, sea waves of all lengths up to a maximum dependent on the wind velocity are generated. Of this multiplicity of waves, some travelling ...

    Notes: [Auszug] If instead of the cavity being used to control the oscillator frequency, as in Essen's method, it is used to produce a phase change in a signal from a fixed -frequency oscillator, greater sensitivity can be obtained. The method is demonstrated in principle in Fig. 1. The output of an oscillator ...

    Notes: [Auszug] To evaluate true absorption of ultra-violet light without interference from effects of variable geometrical distribution of the transmitted light, several techniques were applied and found to yield the same results. A fluoroscopie photometer4 was applied in some instances because it intercepts and ...

    Notes: [Auszug] Suppose that four treatments are represented by the letters A, B, C, D. Consider the sequence A ; B, C, A, D ; A, C, B, D ; C, D, B, A. This is an example of a serially balanced sequence for four treatments. More generally, for t treatments, a serially balanced sequence is defined as follows : ...

    Notes: [Auszug] If the identification of this source with the nucleus of the Galaxy is accepted, then at a distance of 8 k.parsecs the diameter of the nucleus would be about 150 parsecs, which is small compared with that of the nucleus of a typical spiral nebula similar to our Galaxy. Furthermore, a careful study ...
