TL;DR: In this paper, it was shown that the cosmic noise radiation is not observable at frequencies lower than a few megacycles per second, owing to the screening action of the ionosphere.
Abstract: THE discovery of electromagnetic 'noise' radiations at radio frequencies was first made by K. G. Jansky1 who, in a series of measurements at about 20 Mc. s. ( 15 m.) was able to establish the close connexion between the direction of greatest intensity and the centre of the galaxy. G. Reber2 later made measurements at 160 Mc./s. ( 2 m.), and he was able, by virtue of a narrower beam, to detect a number of subsidiary peaks. He found the intensity of radiation at this higher frequency was very much less ; he also suggested a probable explanation of the radiations, namely, the interactions in encounters between positive ions and free electrons released from interstellar gases by the photoelectric action of stellar radiations. The theoretical treatment for radiation arising from such encounters was first given by H. A. Kramers3 to account for continuous radiation in X-ray spectra. The cosmic noise radiation is not observable at frequencies lower than a few megacycles per second, owing to the screening action of the ionosphere.

TL;DR: This work has shown that an interaction between protein and sugar is demonstrated by the infra-red absorption spectra of mixtures of the two, and this system was studied in the hope that a similar approach might yield information about antibody–antigen reactions.
Abstract: A COMMUNICATION by Goulden1, stating that an interaction between protein and sugar is demonstrated by the infra-red absorption spectra of mixtures of the two, prompted us to study this system in the hope that a similar approach might yield information about antibody–antigen reactions.

TL;DR: In this article, the lead sulphide photo-conductive layers are used as sensitive detectors in the near infra-red (NIR) channel, but so far their usefulness has been limited to wave lengths less than about 3 µ.
Abstract: LEAD sulphide photo-conductive layers are now known as sensitive detectors in the near infra-red1, but so far their usefulness has been limited to wave-lengths less than about 3 µ.

TL;DR: In this paper, it was shown that a perfectly spherical target will appear to produce two orthogonally polarized circular components differing in magnitude by 40 dB and 20 dB, respectively, if the voltage ellipticity ratio of the radiated wave is 0.99 and 0.9.
Abstract: MEASUREMENTS on the polarization of radio waves reflected from meteorological precipitation are sometimes handicapped by limitations of the investigating radar, and this is particularly so in the case of so-called circularly polarized radars. In practice, all radars radiate an elliptically polarized wave, and it can be shown that a perfectly spherical target will appear to produce two orthogonally polarized circular components differing in magnitude by 40 dB. if the voltage ellipticity ratio of the radiated wave is 0.99, and by 20 dB. if the ellipticity ratio is 0.9. This sets a limit to the accuracy obtainable in field measurements.

TL;DR: In this article, a study of the behaviour of the aluminium-solochrome violet RS complex is made over the range pH 195 to 1008 and it is shown that two distinct complexes are formed, determining the number of electrons per molecule transferred in the reduction of these complexes are made and values for the ratios of dye to aluminium are also obtained.
