XXXIX. The absorption of the K X-rays of silver in gases and gaseous mixtures

P. W. Burbidge1922-02-01The London Edinburgh and Dublin Philosophical Magazine and Journal of Science

1. (1) The total absorption coefficient of silver K radiation has been measured in air, carbon dioxide, sulphur dioxide, methyl iodide. 2. (2) Using this silver K radiation, it has been shown by di...

The mechanism of ciliary movement

J. Gray1922-02-01Proceedings of the Royal Society of London Series B Containing Papers of a Biological Character

Abstract The mechanism of ciliary movement has been extensively studied from the morphological point of view, and although there is a general consensus of opinion as to the structure of the “ciliary apparatus,” there is no adequate account of the functions of the various parts of the mechanism. The material used for t…

Wave Form and Amplification of Corona Discharge

J. B. Whitehead、N. Inouye1922-01-01Transactions of the American Institute of Electrical Engineers

Corona forms on a round wire or cable when the voltage is raised to such a point that the voltage gradient near the wire is sufficiently high to break down the insulating properties of the air. The larger the wire the higher the voltage to cause corona. The corona is luminous and ionizes the air, giving it electrical…

Proteins and the theory of colloidal behavior

Jacques Loeb1922-01-01OpenAlex

crepancies will have to be accounted for, and many additions made. It was, however, thought advisable to publish the book for the reason that the experimental facts are accumulating so rapidly that it is difficult for anyone to gather the leading ideas unless they are presented more systematically and with less detail…

THE SYNTHESIS OF INACTIVE PARA- AND ANTI-HYDROXYASPARTIC ACIDS (AMINOMALIC ACIDS)

H.D. Dakin1921-10-01Journal of Biological Chemistry

The increasing recognition of the importance of the hydroxyamino-acids in protein chemistry is an incentive to their more complete investigation.The particular case of hydroxyaspartic acid or aminomalic acid is of interest for several reasons.It represents the lower homologue of p-hydroxyglutamic acid already identifi…

COMPARATIVE HYDROLYSIS OF GELATIN BY PEPSIN, TRYPSIN, ACID, AND ALKALI

John H. Northrop1921-09-20The Journal of General Physiology

A comparison has been made of the relative velocity of hydrolysis of the various peptid linkings of the gelatin molecule when hydrolyzed by acid, alkali, pepsin or trypsin. It has been found that: 1. Those linkages which are most rapidly split by pepsin or trypsin are among the more resistant to acid hydrolysis. 2. Th…

The Distinction between Intrinsic and Spurious Contact E.M.F.S and the Question of the Absorption of Radiation by Metals in Quanta.

R. A. Millikan1921-09-01Physical Review

Stopping potentials for photo-electrons from Na, K and Li surfaces, as determined with a Faraday cylinder in vacuo for monochromatic ultraviolet light, were found to be accurately the same for all. This result makes general the conclusion that the stopping potential for a given frequency is the same for all clean meta…

The Use of Graphs in Palaeontology

H. H. Swinnerton1921-09-01Geological Magazine

To illustrate the value of graphic methods when changes in a number of distinct structural elements are studied, examples may be taken from the Carboniferous corals. These are well suited to the purpose, because thin slices yield so much information and are easily measured. In Fig. 4 a diagrammatic section is shown of…

The Laws of Absorption of X-Rays.

F. K. Richtmyer1921-07-01Physical Review

Measurement of Absorption of X-rays.---The use of a filtered beam of rays can at best give only approximate values of the coefficients, for such a beam is not homogeneous. It is pointed out that logarithmic absorption is no proof of homogeneity. In these experiments homogeneous radiation was secured by using a Bragg s…
