    Hall, Robert Dale, 1947-
    Abstract:
    The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research.

  • Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

    Creator:
    Chorzempa, Mary André, Sister
    Abstract:
    Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...

  • The development of the chlorinity-salinity concept in oceanography

    Creator:
    Wallace, William J.
    Abstract:
    This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...
