Professional sociology in the U.S. began as a field area within economics, but gradually emerged as a separate discipline. Using new data on joint meetings and the separation of departments, I track interdisciplinary relations through three phases: sponsorship (1890-1905), collaboration (1905-1940), and disengagement (post-1940). In the early years, sociology was mostly a branch of economics de...

In the process of photosynthesis in Cklorella it is now known that the oxygen liberated during CO2 fixation and reduction originates from water (Ruben et al., 1941). I t is further known that in some algae (not ChloreUa) one can obtain carbon dioxide fixation and reduction without the release of oxygen (by adaptation to hydrogen, Gaffron, 1940, 1942 a, 1942 b, Gaffron and Rubin, 1942) and that ...
