    Notes: [Auszug] After a number of pilot experiments the following technique was adopted. The abdominal cavities of rats (Albino Wistar strain) at 15 days pregnancy were opened under open ether anaesthesia. The uterus with its contained conceptuses was removed, but the ovaries left intact. A portion of yolk sac was ...

    Notes: [Auszug] It seemed to us that the demonstration of par-ticulate absorption, however small, might be of interest to those working on the absorption of relatively insoluble elements required in only trace amounts. In this connexion it may be of interest to record that we are endeavouring to determine the ...

    Multibeam receiver for millimeter-wave radio astronomy (1988)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 59 (1988), S. 1911-1919 
    Details

    Notes: An eight-beam receiver system for millimeter-wave radio astronomy is described. The receiver is designed to map spatially extended radio sources in both spectral line and continuum emission at a wavelength of 1.2 mm. This receiver is now in use on the 12-m radio telescope on Kitt Peak in Arizona.

    Rangefinder with fast multiple range capability (1992)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 63 (1992), S. 3311-3316 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A rangefinder is described that uses the propagation time of a beam of infrared radiation to measure distances of up to 120 m with errors of less than 50 μm. The instrument is capable of measuring up to five different distances per second by directing an amplitude modulated infrared beam to a retroreflector located at the far end of each path. The instrument is being tested with the expectation that such a system could be used to make precise and rapid measurements on a large radio telescope. Such measurements would be used to adjust the shape of the telescope reflector surface to correct for thermal and gravitational deformations taking place during astronomical observations. It is possible that the measuring system could be extended to relate the positions of certain moving parts of the structure to a reference system fixed in the ground, thus opening the possibility of making corrections to the telescope pointing.

    Notes: [Auszug] It was decided to see if inert particles would be taken up in the same way as bacteria. Previous experiments of this kind, using inert particles such as carmine5, graphite6 and polymethyl methacrylate spheres7, to imitate bacteria have had limited or no success, for even when fed in large amounts ...
