Nov. 18, the Utah Chapter of the Sierra Club is sponsoring spon-soring a comprehensive workshop on Utah's nuclear waste problem. "Utah is well on its way to becoming the nation's foremost radioactive waste dump and the public needs to know the issues. Radioactive waste is now entering Utah and traveling in trucks on our major freeways. New proposals propos-als would immensely increase the quantity and toxicity of radioactive radioac-tive waste stored in Utah." said Teri Underwood. Sierra Club board member organizing the workshop. The workshop entitled "Empower Yourself To Stop Nuclear Waste" is being held to inform the public about the radioactive waste that is currently coming into Utah and the new proposals to bring in vast quantities quanti-ties from all over the US. The politics behind the proposals: propos-als: the health, environmental and socioeconomic impacts; here it is going; and what are the dangers will be some of the issues dis- cussed. Speakers ii! identify actions that can be taken by the public to stop the influx of waste. There will be a panel discussion at the end. The public is asked to participate. Speakers include Connie Nakahara. PE , J D , Director of the High Level Nuclear Waste Opposition Office at the Utah Department of Environmental Quality; Chip WaiJ. author of "Canaries on the Rim," Ken Sleight, long-time environmentalist environmental-ist and friend of legendary Ed ard Abbey: Mary Dickson, journalist and director creative services KLFD-Channel 7; and other noted community activists. The workshop will be held on Saturday, Nov. IS from 8.30 a.m. to 1.30 p m at the First Unitarian Church. 569 South 1300 East in Silt Lake City. Seating is limited.

Bureau of Reclamation to explore Pineview drilling ft -X 'v A. ,;?THAHK YOU AT? mwm mm i m Ua mm WOHDERFUL SUMMER! The Bureau of Reclamation will make use of low water conditions condi-tions at Ptnevtew Dam to conduct additional exploratory drilling at the dam. Drilling will take place on the upstream face of the dam. Because of low water conditions condi-tions in the reservoir following the very dry summer of 2000. there is an opportunity to collect drill core data at positions on the upstream face that normally are covered with water. Reclamation has already drilled a number of exploratory holes on the downstream side of the dam over the past several years to collect geologic data used in designing modifications to the dam to ensure protection of the facility in the event of a major earthquake. Modification design plans are currently being developed wtth construction scheduled to begin next year. These plans have been discussed dis-cussed in public meetings in the Oeden and Weber County area over the past two years. Both the Ogden River Water Users Association and the Weber Basin Water Conservancy District, who operate the dam and associated water projects, are partners with Reclamation in the planned mtnJi-fication mtnJi-fication work. Initial construction of Pineview Dam was completed in 1937, at a height of 103 feet. In 157. it was enlarged to its present height of 137 feet, creating a 110.0UO acre-foot reservoir supplying sup-plying water to Kith projects. Some modification was made to Pineview Dam in 12 with the addition of a berm on the down stream face. This was to provide added stability sta-bility in an earthquake. Since then, additional studies have been conducted con-ducted to provide design data for a permanent modification based upon detailed geologic information informa-tion obtained through the 1990s Drilling information obtained this winter will be incorporated into the final design. Other than occasional interruptions interrup-tions to move equipment, persons traveling on S R. 39 and S R. 158 over the dam should not be inconvenienced. I Thanks to our special crew!

BiS-7337 TE Burning candle at both ends is hard on the ticker Graveyard shifts promote higher heart disease as well as errors, accidents Shift work not only can lead to errors and accidents at the work place, but could explain the reason night-shift workers have a higher risk of cardiovascular disease, dis-ease, according to a study in Circulation: Journal of the American Heart Association. Nerve end chemical messages that control the heart's activity-seem activity-seem to stick closely to a 24-hour pattern, regardless of changes in awake and asleep times. "This resistance of the body's internal "clock' to change with varied work schedules indicates that people dont adapt as easily as we think to shift work, and could explain why shift workers are at hiEhcr risk." savs Raffaello Furlan. M D . professor profes-sor at the University of Milan and senior registrar in internal medicine at Hospital L, Sacco in Milan. Italy. 'Researchers showed that of Cortisol a stimulant hormone hor-mone that drives the nerve systems sys-tems that keep the heart rate, digestive system, breathing and other functions running at a quicker pace during the day are generally lower at night. In the study, the normal morning peak levels did not "shilt" with the workers' nighttime night-time schedules. "The heart rate is continuously continuous-ly changing on a beat-by-beat basis." says Furlan. "In this study we looked at two types of nerve systems that regulaie the heart." The nervous system plays a major role in adapting the human body to different physiological physio-logical conditions and environmental environ-mental demands. The sympathetic nerves act like accelerators for bodily functions func-tions such as heart rate and digestion. .The vagal nerves act as decelcrators. As one nerve activated when a person is stand ing up or is engaged in physical activity or mental stress, whereas the vagal nerves become more active when a person is lying down or at rest, explains Furlan In general, the accelerator nerves are more active during the day and the decelerator nenes are more active in the evening, especially overnight. Researchers measured the 24-hour 24-hour changes of the nerve activity activi-ty that controls the heart in workers who were rotated through three different shifts night (10 p.m. to 6 a m ). afternoon after-noon (2 p m. to 10 p.m.) and morning (6 a m. to 2 p.m.). Twenty -four hour electrocardiogram electrocar-diogram recordings were done after a two-day adaptation to the present shift and during a weekly rotation of the men through all three shifts. Furlan's team examined the nerve influences on the heartbeat heart-beat throughout the day. Chances in the heart rate were measured by a computer-based computer-based technique called power spectrum analysis, with the low frequency component measuring the nerve activity that accelerates acceler-ates the heart and the high frequency fre-quency measuring the decelerating decelerat-ing influences. The researchers found that nerve activity that accelerates the heart was lower during the overnight shift compared com-pared to morning or afternoon working periods. Because of the lower nerve acttv ity at night, a person may be in poor biochemical condition and less able to perform mental and physical tasks, says Furlan. The researchers hypothesized that continually shifting the nerve influence on the heart, o er years, might play a role in the excessive rate of cardiovascular cardiovas-cular and gastrointestinal diseases, dis-eases, and of sleep disturbances described tn habitual shift workers work-ers in previous studies. ?--t i t4 ? . - Si - a : - m - fi " ... -J' 3 I -cf 'J lit - f5. .? e 2 Adpissions Open Houses Wednesday.
