N / m 2 ) and subjecting it to an electri cal field of 6 Χ 105 V/cm for about 1 hr; this process is repeated for three consecutive days. Devices are then formed by cutting out squares and con structing a sandwich from two pieces. Tests of the sensor, irradiated from a 500 Κ black body source, show its de tectivity to be 4 Χ 105 cm H z ^ V W and its responsivity to be 0.1 V/W (both at 25 Hz) with a response time of a few seconds. Improved polarization techniques and electronics have pro duced detectors with performances ap proaching those achieved by conven tional crystal pyrodetectors. The advantages of such inexpensive detectors would be great. Besides be ing cheap, these sensors would be sensi tive, rugged, easily made and shaped, would require no cooling, and might have frequency response superior to other thermal detectors.
International Water Resources Association An international organization called the International Water Resources As sociation (IWRA) has been founded as a nongovernment, nonprofit scientific organization. It was incorporated in the State of Wisconsin of the U.S. This Association results from the efforts of an international group of well-known administrators, engineers, executives, and scientists representing many dis ciplines of the water resources field. Further information concerning objec tives and membership application forms is available by writing to G. M. Karadi, Secretary General of IWRA, E320, Sci ence Complex Bldg., University of Wis consin-Milwaukee, Milwaukee, Wl 53201, USA.
