Seven New White-winged Doves from Mexico, Central America, and Southwestern United States

Description: Seven new subspecies of the white-winged dove (Zenaida asiatica) are described. The patterns of these recoveries are an invaluable aid to understanding racial distribution of this species. The extent of migration that breed in Central America is not yet adequately known. The range of the doves extends as far north as the southwestern United States.

Infrared Spectroscopy of Carbohydrates: A Review of the Literature

Description: Report presenting of survey of the literature on the infrared spectroscopy of carbohydrates in order to assemble and systematize information in this field. Discusses principles and instrumentation, sampling techniques, comparison of samples, and the interpretation of the spectra. In addition, examples are discussed of the use of infrared spectra for qualitative and quantitative purposes and in the determination of structure. Special techniques are briefly described.

Design and Testing of a High-Heat Flux Electron-Bombardment Heater

Description: Report issued by the Argonne National Laboratory discussing the testing of an electron-bombardment heater. As stated in the abstract, "the applications of electron-bombardment heating to liquid-metal heat transfer and reactor safety experiments are discussed. The design of a high-heat-flux, electron-bombardment heater (EBH) is presented" (p. 7). This report includes tables, illustrations, and photographs.

Cosmic Ray Produced Ar37 and Ar39 Activities in Recently Fallen Meteorites

Description: Several methods of determining meteorite ages depend ages upon nuclides formed by cosmic ray interactions. The tactic assumption is always made that the intensity of cosmic radiation does not vary in time or space. However it is known that the intensity of cosmic radiation at the earth varies with the solar activity. The spectrum of cosmic ray protons and alpha particles exhibit a marked drop at the low energy end (<1.5 GeV) and the intensity in the region appears to follow the 11 year cycle of… more

The Mg-MgCl2 System — A Chronopotentiometric Study

Description: The mode of dissolution of magnesium in molten magnesium chloride contacted with Mg-Pb alloys was studied at 750°C using anodic chronopotentiometry. An inert tantalum anode was used to determine relative amounts of magnesium dissolved in its chloride as a function of magnesium activity in the alloy. According to the law of mass action a linear dependence of magnesium solubility on a Mg indicates Mg2Cl2 as the reaction product and a parabolic dependence indicates MgCl. It was found that the amou… more
