A method is described to measure refractive indices of gases at atmospheric pressure and at a frequency of 25,000 Mc/s. The method is based on the change in resonance frequency of a cavity, first filled with a reference gas (nitrogen) and after that with the gas of which the refractive index is to b
A number of indices of community dissimilarity based on the species diversity measures have been proposed during the last three decades (Margalef 1956, 1957; Kohn 1959; MacArthur 1965; Horn 1966; Glowaciński and Järvinen 1975; Järvinen and Väisänen 1976). Each of them is measuring the wrong quantity
