    Annotated record and Radium content of the detailed examination of manganese nodules from lakes and peripheral waters of Russia as well as the Pacific Ocean (1937)
    PANGAEA
    In:  Supplement to: Kurbatov, L M (1937): On the radioactivity of bottom sediments. American Journal of Science, s5-33(194), 147-153, https://doi.org/10.2475/ajs.s5-33.194.147
    Details
    Publication Date: 2023-08-28
    Description: At the date of publication the radioactivity of bottom sediments had only been published by a few authors. The radioactivity of selected characteristic ferro-manganese formations samples taken from different seas and lakes has been determined. This investigations covers nine seas and lakes of the U.S.S.R., and for comparison, two manganese concretions from the Pacific.

    Heat Transfer and Hydraulic Flow Resistance for Streams of High Velocity (1943)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: Problems of hydraulic flow resistance and heat transfer for streams with velocities comparable with acoustic have present great importance for various fields of technical science. Especially, they have great importance for the field of heat transfer in designing and constructing boilers.of the "Velox" type. In this article a description of experiments and their results as regards definition of the laws of heat transfer in differential form for high velocity air streams inside smooth tubes are given.

    The Effect of Streamlining the Afterbody of an N.A.C.A. Cowling (1939)
    In:  CASI
    Details
    Publication Date: 2019-08-26
    Description: The drag and the power cost associated with the changing of the nose of a nacelle from a streamline shape to a conventional N.A.C.A. cowling shape was investigated in the N.A.C.A. 20-foot tunnel. Full-scale propellers and nacelles were used. The increment of drag associated with the change of nose shapes was found to be critically dependent on the afterbody of the nacelle. Two streamline afterbodies were tested. The results fo the tests with the more streamlined afterbody showed that the added drag due to the open-nose cowling was only one-fourth of the drag increase obtained with the other afterbody. The results of this research indicate that the power cost, in excess of that with a streamline nose, of using an N.A.C.A. cowling in front of a well-designed afterbody to enclose a 1,500-horsepower engine in an airplane with a speed of 300 miles per hour amounts to 1.5 percent of the engine power. If the open-nose cowling is credited with 1 percent because it cools the front of the cylinders, the non-useful power cost amounts to only 0.5 percent of the engine power.
