Free Energy And Entropy Of Translation Tables, Paul W. Gilles, Gordon A. Gallup
Free Energy And Entropy Of Translation Tables, Paul W. Gilles, Gordon A. Gallup
Gordon Gallup Publications
In the statistical calculation of the thermodynamic properties of ideal gases the translational contribution is calculated from the Sackur-Tetrode equation, S = R1n (2π MkT)3/2 ÷ (h3 N5/2) V + 5/2 R in which S is the entropy of one mole of a gas of molecular weight M, at absolute temperature T, and volume V expressed in cubic centimeters; k is Boltzmann's constant; h is Planck's constant; N is Avogadro's number; and R is the molal gas constant expressed in the same units as those desired for S, usually cal deg1 mole1.
The Pairing Effect In Nuclei And Isomerism, Robert Katz
The Pairing Effect In Nuclei And Isomerism, Robert Katz
Robert Katz Publications
Previous workers have shown from an analysis of the energetics of alpha and beta decay that the pairing energy of protons is greater than that of neutrons. It is here postulated that this effect is responsible for the absence of odd-proton isomers for 50
An Investigation Of The Collision Lengths Of Penetrating-Shower-Producing Radiation In Various Materials, James Francis Kenney
An Investigation Of The Collision Lengths Of Penetrating-Shower-Producing Radiation In Various Materials, James Francis Kenney
Physics & Astronomy ETDs
The purpose of this paper is to compile and tabulate some of the experimental data that have been obtained on penetrating showers, and to compare these data with the results that should be expected from the various theories that have been advanced.
On Air Density Measurements Using The Alpha-Particle Range Method, Gus Tom Zorn
On Air Density Measurements Using The Alpha-Particle Range Method, Gus Tom Zorn
Physics & Astronomy ETDs
The density of the air is in general determined from a knowledge of the pressure and temperature by applying the ideal gas law. This law may be stated in the following for; p=MP/TR, where p is the density of the air in gm/cm3, M is the gram molecular weight, P is the pressure in dynes/cm2, T is the temperature in degrees kelvin and R is the universal gas constant in ergs per degree absolute for one mole. This method is also used in the determination of the air density as a function of the height in …
Experiments On The Life Of Self-Quenching Geiger Mueller Counters, Raymond C. Opperman
Experiments On The Life Of Self-Quenching Geiger Mueller Counters, Raymond C. Opperman
Physics & Astronomy ETDs
Because of the several superior properties of counters containing organic vapor as a quenching agent, it is desirable to extend the life of such counters. It is, therefore, of interest to determine the relative importance of factors which limit their useful life. It is also worthwhile to further the investigation of counters containing an inorganic gas as a quenching agent.

An Azimuth-Stabililzed Balloon Platform, Alfred H. Spano
Physics & Astronomy ETDs
In the study of Zodiacal Light, an interesting task is the determination of the intensity and the position of this glow on the celestial sphere. The problem of photographing this phenomenon from the earth’s surface has been hampered generally by the inevitable presence of the atmosphere between the camera and the object. However, it is expected that at the height of some thirty kilometers above the earth, the atmospheric haze will be reduced enough so that pictures of the zodiacal region may be obtained without significant absorption. To accomplish this, it is necessary to keep the balloon-borne camera pointed in …
Use Of A Simple Blowing Device To Facilitate Inspection Of Wheat For Internal Infestation, Max Milner, E. P. Farrell, Robert Katz
Use Of A Simple Blowing Device To Facilitate Inspection Of Wheat For Internal Infestation, Max Milner, E. P. Farrell, Robert Katz
Robert Katz Publications
Enforcement of sanitary practices in the commercial handling of wheat, particularly with reference to insect infestation, requires a method of inspection of wheat for internal or hidden insect infestation which is reliable, yet rapid enough for routine use. A number of inspection methods have been developed for this purpose, and a review has been published (1) of those proposed up to two years ago. A rigorous evaluation of several of these techniques has been made recently (2).
The rapid inspection method suggested to the grain trade by the Food and Drug Administration (2), based on the results of an extensive …
Application Of The Polaroid-Land Process To Radiographic Inspection Of Wheat, Max Milner, Robert Katz, M. R. Lee, W. B. Pyle
Application Of The Polaroid-Land Process To Radiographic Inspection Of Wheat, Max Milner, Robert Katz, M. R. Lee, W. B. Pyle
Robert Katz Publications
At a time when the technique of X-ray inspection of grains for internal insect infestation, announced almost two years ago, appears to have gained considerable currency in industries handling and processing grain, there exists the general feeling that these industries would be more receptive to any technique which would even further simplify and expedite the radiographic inspection process. To this end Kansas State College and the Picker X-Ray Corporation have engaged in a cooperative study relating to the application of the Picker-Polaroid photographic process to the determination of internal infestation in grain. This process is based on the principle of …
On The Theory Of Head Waves, Patrick Heelan
On The Theory Of Head Waves, Patrick Heelan
Research Resources
When a combined longitudinal and transverse disturbance, diverging from a localized source, strikes a plane boundary between two solid elastic media, several systems of head waves and second order boundary waves are generated, each associated with grazing incidence of one or the other of the reflected or refracted waves. Associated with grazing incidence of P 1 P2, the refracted P-wave, is the head wave system comprising P1P2P1 (the "refracted wave" of seismic prospectors), and P1P2S1 (a transverse head wave) in the upper medium, and P1P2 …
