A far-off resonance trap (FORT), in contrast, uses tire dipole force ratlier tlian tire spontaneous force to confine atoms and can therefore operate far from resonance witli negligible population of excited states. A hybrid MOT/dipole-force trap was used by a NIST-Maryland collaboration [26] to study cold collisions, and a FORT was...

In the case of a porous medium the characteristic difficulties of the intermediate case can be circumvented by a device originally introduced by Maxwell [16] and later exploited in some detail by workers from Oak. Ridge National Laboratory and the University of Maryland [I ]—[21]. The idea was stated very succinctly by Maxwell as follows. "We may suppose the action of the porous material to be similar to that of a number of particles, fixed in space and obstructing the motion of the particles of the moving systems". ...

In Japan, scrap tires are used to fuel Pordand cement kilns. The process was developed by the Bridgestone Tire Company and has increased gready in importance since 1980. The Saitama plant (Nihon Co., Ltd) bums 140,000 tires, as weU as oil, per month to produce 258,300 t of cement (qv) per month (17). Cemenergy (Loomis, California) and Emanuel Tire Company (Baltimore, Maryland) cement companies and paper mills bum scrap tires to produce process energy (18,19). It has been predicted that 238 million passenger and tmck tires wUl be consumed by the energy market aimuaUy by 1997 (20). 

Small tire chips have also been utilized as a soil amendment to improve athletic playing fields (see Recreational surfaces). A patented process marketed under the trade name Rebound (fai Tire) combines cmmb mbber from scrap tires with composted organic material to reduce soil compaction, resulting in better athletic playing surfaces (52). Installations have been made in Florida, California, Colorado, Hawaii, Maryland, Michigan, Missouri, Nevada, Virginia, and Wisconsin. 

When the NRC, headquartered in Rockville, Maryland, took over the responsibiUties of the AEC in 1974, many of the AEC s research and development functions, particularly many covering new technology development and nuclear weapons production, were assumed by the U.S. Department of Energy. However, the NRC has maintained some research and developmental capabiUties which are handled by the NRC s Office of Nuclear Regulatory Research. 

A thorough review of the health aspects of talc was presented ia an EDA-sponsored seminar ia Bethesda, Maryland, ia January 1994 (9). The executive summary states that the probabiUty of human risk is likely nonexistent under customary conditions of use. Used for decades ia a wide variety of cosmetic and other appHcations, talc has proven to be among the safest of all consumer products.

In 1949 the World Health Organization adopted the biological activity of 1 mg of an oil solution containing 0.025 p.g of crystalline D as the analytical standard for vitamin D. This standard was discontinued in 1972. USP uses crystalline cholecalciferol as a standard (80). Samples of reference standard may be purchased from U.S. Pharmacopeia Convention, Inc., Reference Standards Order Department, 12601, Twinbrook Parkway, Rockville, Maryland 20852. One international unit of vitamin D activity is that activity demonstrated by 0.025 ]1 of pure crystalline (7 -vitamin D. One gram of vitamin D3 is equivalent to 40 x 10 lU or USP units. The international chick unit (ICU) is identical to the USP unit.
