The bonds within the molecules' sugar and phosphate backbones remained intact and therefore had only a minor influence on the force mea...... Describing a new U.S. study of the worlds first atomic explosion on July 16, 1945 in New Mexico, health physicist Tom Widner ( TWidner@chemrisk.com ) will present the first preliminary estimates of total radiation dose to nearby residents, including some who lived less than 20 miles away but went undetec...Translating form into function
