Behind every new nuclear discovery there lies tens of thousands, of hours of patient laboratory spade work in the analysis of hundreds of thousands of photos. In die past few years, a device that greatly speeds the analysis of bubble chamber tracks has been ceived, developed and built in the Laboratory for Nuclear Science at MIT by a research group under the direction of Irwin Pless. Called PEPR (for Precision Encoding and Pattern Recognition) , the device consists of a cathode ray tube, a lens and a photomultiplier controlled by a specialy designed and programmed computer which automatically analyzes the special film used in bubble chamber experiments. It follows the bubble tracks of events of interest while ignoring others, and measures the particles paths to an accuracy of one micron. This degree of precision is comparable to that of the finest machine screws; one micron is the thickness of a hair. PEPR increases nuclear data output by a factor of about 60, measuring some 200 events per hour as opposed to the 3 to 4 event per hour rate of manual interpretation. Both speed and accuracy are extremely important," Dr. Pless points out, because the sitution in physics is one of almost discouraging richness. A good deal of the prospecting is now done and what one wants is tremendous amounts of data on the properties of known particle states, the varieties of decay modes, interactions and so forth. A high energy experiment will typically produce 200 to 300 thousand reactions and the big accelerators are now generating better than four million photos a year. Some 16,000 events was a good years work for a highly trained analyst; 160,000 events by no means untypical of a number one would want to search tlirough for a series of complex interactions would take 10 man years by the old metliods of manual measurement. It's very precise work because particle identification depends on close correlation of four measurements angular momentum in three dimensions, and energy. , l-5- 0th Pesticides Evaporate into the Atmosphere, Chemists Say Only five to ten percent of most pesticides added to the environment can be accounted for, and scientists now suspect that a significant, if not major, portion passes into the atmosphere, the American Chemical Society was told at its 163rd national meeting. Under the influence of sunlight, humidity and oxygen. airborne pesticides may be expected to undergo quality control programs, makeup of auto trips, the progress and problems in traffic safety, and the impact of motor vehicles on the nations economic welfare. Among the many interesting points made in the book are: A new car purchase requires 27 per cent of a familys annual income than 20 years ago; Hoad mileage has increased only 18 per cent in the last 50 years while vehicle travel has risen 1800 per cent. (the average vehicle traveled more than 10,000 miles in 1971. The average age of cars in use is nearly 5.7 years. Designed as a ready reference for writers and speakers, government, civic and business leaders and others with a professional interest in motor vehicle use, 60,000 copies of the book will be distributed starting this week. Copies also are being sent to public and college libraries. A sister publication, Motor Truck Facts, will be published next spring to present year end 5SHSH A elt AS ED GRAPEVINE Two Bureau of Outdoor rec- reation grants for Utah totaling $284,441 were approved. One went to the Utah Division of Parks and Recreation and was for the development of 42 campground sites at the Wasatch Park site. The other grant was for $49,106 and went to the Salt Lake County Commissioners to acquire nine acres of land. . .

First, the evaportion of pesticides ice in the matters of ecology are from crops presents another form of air pollution. If we find that significantly high concentrations of a pesticide persist unchanged for long periods in the atmosphere in a given locale, then the possibility of damage to crops, human health and wildlife must be considered. Second, if decomposition does occur, it is important to know what kinds of compounds pesticides are converted to once they get into die atmosphere. The possibility exists that a presumably safe pesticide can be transformed to some other substance which would be harmful to humans or some other innocent life form. On the other hand, pesticide breakdown in the atmosphere may represent a natural method of environmental cleansing the atmosphere may provide a gigantic furnace in which chemicals are burned to nontoxic products. The knowledge about how pestidcides are broken down in the atmasphere will put the public in a better position to influence this process to our benefit and to prevent potentially dangerous situations from developing. Third, only a small proportion of the worlds pesticides remain environmentally accounted for. Both the qualitative and quantitative results of our research should go far in helping to define what happens to pesticides. Our research requires laboratory simulation of atmospheric photodecomposition under controlled conditions, identification and analysis of the decomposition Products, and finally a search for these products (and parent pesticide) in the air above treated areas. oOo A childs stuffy nose and flits of sneezing may not be a cold at all, but a manifestation of allergy.

The University of Utah has gained from a national pharmaceutical firm funds for the Utah Department of Pharmacology to establish a distinguished lectureship in health sciences. The Smith, Kline and French laboratories will provide $3,000 annually for three years to bring eminent health scientists to the campus. . The Salt Lake City Commission amended its ordinance dealing with closing hours of muni- cipal parks. The City Court re- cently ruled that the ordinance was unconstitutional in that the law was overly broad with to some defendants who who attempted to use the parks as a campingg round and staging areas for a protest. The ruing said that the ordinance gave the City Parks Department the discretion to waive the closing time regulations without any criteria. ref-ere- nc Two Salt Lake City officials arrive in New York to make a formal bid to have the 1976 Olympic games held in Utah, but only on certain given conditions and only in strict financial and ecological help will be met.
