Seite 382 - Bohr theory to apply to absorption as well as to emission, we should have vKt = 0 (28) THE STARK EFFECT FOR HYDROGEN Stark and Lo Surdo have found that some of the emission lines due to gaseous atoms in an electric field of the order of 100,000 volts per cm are split up into a number of components. Confining our attention to hydrogen, the following experimental facts are observed: (1) Each Balmer line is split up into a number of components. (2) The number of components increases with the series...

Seite 222 - ... animals to be compared must be as nearly alike as possible. The plan contemplates the comparison of the animals by pairs, one animal of each pair receiving the high-protein and one the low-protein ration. The two animals of each pair should be of substantially the same breed (not necessarily pure-breds) and as nearly as possible of the same age and weight at the beginning of the experiment. It is desired that as many pairs be used as is consistent with the keeping of individual records. Lot records...
Seite 324 - The committee has apparently felt constrained to propose a new plan which is a substantial departure from those methods and agencies now existing and well known to the people of the State. A somewhat radical change is purposed in our methods of administration when it is proposed to substitute in place of most of the existing commissions a system of departments and bureaus, with directors, chiefs of divisions and minor heads, all holding office directly or indirectly at the pleasure of the Governor.
