E.Item The non-singular collineations of three dimensional space, their classification and invariant elements(1919) Dean, Alice CrowellItem Adsorption by precipitates(1919) Sherrick, Jacob LeightyFrom the results of this investigation the order of adsorption of the ions by precipitated barium sulphate is: ferrocyanide > nitrate > nitrite > chlorate > permanganate > ferricyanide > chloride > bromide > sulphocyanate > iodide, the ferrocyanide ion being adsorbed the most and iodide the least. From a consideration of this order and of the absolute amount of adsorption in each case we find very little reason to place much credence in Schulze's law. Although we find a quadrivalent ion the most strongly adsorbed, we find four univalent ions more strongly adsorbed than the trivalent ferricyanide. Furthermore, contrary to what is implied in Schulze's law, we find a very wide variation in the amount of univalent ions adsorbed. This amount varies from 8.482 gram anions per 100 mols for nitrate to 0.056 gram anions per 100 mols for iodide ion. If the adsorption values are expressed in gram anions instead of gram equivalent anions the order becomes: nitrates > nitrites > chlorate > ferrocyanide > permanganate > chloride > ferricyanide > bromide > sulphocyanate > iodide, the nitrate ion being adsorbed the most and the iodide the least. Here there is nothing even to suggest Schulze's law.Item Labor legislation in Texas, a survey of the labor laws of Texas(1919) Barber, Helen BrowderItem The luminosity of mercury vapor distilled from the arc in vacuo(1920) Ricker, Norman HurdItem Adsorption of precipitating anions by colloidal hydrous oxides(1920) Middleton, Edmund Burrus (b. 1897)Item Colloidal barium sulphate(1920) Porter, Everett EllisItem The Mexicans in the Southwest(1921) Snoddy, ElizabethItem Thomas Hill Green's criticism of hedonism(1921) Arrowood, Charles Flinn (1887-1951)Item The oxidation and luminescence of phosphorus(1921) Garrison, Allen DarnabyItem The political theory of recent British idealism(1922) Wilson, Mabel VirginiaItem Neighborhoods; a modern survival of the instinct of mutual aid(1922) Lee, Lenoir ValentineItem Naturalism in British ethics(1922) Hathorn, John BroadusItem I. Dielectric losses at radio frequencies in liquid dielectrics. II. The electrical properties of flames containing salt vapors for high frequency alternating currents. III. The conductivity of flames for rapidly alternating currents(1922) Bryan, Andrew BonnellDielectric losses and dielectric constants at radio frequencies for nitrobenzene, water and xylene. The method of resistance variation was used to measure the phase difference psi and dielectric constant K for frequencies between 2 x 105 and 14 x 105 cycles/sec. Special cells were required. (1) Variation with frequency. The results agree approximately with the equations: For carefully dried nitrobenzene at 30°C, psi = .028° + 6.03 x 104/f; for distilled water at 23.5°, psi = 0.8° + 2.09 x 106/ f. These indicate that in addition to the true dielectric loss there is a leakage through the liquid proportional to 1/f. For xylene, psi was too small to measure, less than .01° at 3 x 10 5 cycles. K was found to be practically independent of the frequency, being 2.24 for xylene and of the order of 100 for water. (2) Variation with temperature, for nitrobenzene. K decreased from 42 at 20° to 24 at 14.2°, while psi increased in the same range in the ratio of 7 to 1. These values were obtained, however, for a sample of nitrobenzene for which psi was 12 times as great as for a carefully dried sample.Item Additive and bounded functions of curves(1923) Maria, Alfred JosephIn the present paper we apply the analysis of Vitali to functions of curves of limited variation* To determine the structure of functions of limited variation we associate with every finite function an additive function, called a discard. This discard measures, in a true manner, the quantity by which the function ceases to be absolutely continuous. We demonstrate that the property which characterizes a discard is that the discard coincide with its own discard. We prove the theorem that every function of limited variation can be decomposed into the sum of a function of point values, a continuous function and a finite or infinite number of elementary discards each multiplied by a constant. Finally use is made of the preceding results to find the structure of a function of limited variation hut having no point values.Item Relations of Ovid to the "Faerie Queen" with illustrations(1924) Rowe, Kenneth Thorpe (1900-1988)
