tions were three articles that are quite difficult to read. Brief synopses appear below.Boston Traveler, December 3, 1955 NAVY PULLS OFF OWN ROPE TRICKReliable Communications Aim in Remote Arctic Stretches WASHINGTON (UP) -The Navy has developed its own version of the fabled "Indian rope trick" for reliable communications in the remote stretches of the Arctic.The trick involves suspension of an antenna from balloons trailing about 1200 feet above a ship. With the vertical or "sky hook" antenna a ship in the ice floes of the Arctic is able to maintain radio contact with earth based radio stations in that way.The rest of the article relates the hopes of the Navy in regards to more reliable communication. No Iron for CowsThis article appears to have been cut out and sent in by a reader. It appears that in order to prevent cattle from ingesting nails and bits of iron in feed, strong magnets were placed above the troughs to prevent puncture of intestines during ingestion. Will 'Radar' Stove Need FCC Control?The third article is from "The Evening Star" Washington under the heading "Law in the News" and it was titled "Will 'Radar' Stove Need FCC Control?" by Phil Yaeger and

Background Perioperative hypothermia is a common occurrence, particularly with the elderly and pediatric age groups. Hypothermia is associated with an increased risk of perioperative complications. One method of preventing hypothermia is warming the infused fluids given during surgery. The enFlow™ intravenous fluid warmer has recently been reintroduced with a parylene coating on its heating blocks. In this paper, we evaluated the impact of the parylene coating on the new enFlow’s fluid warming capacity. Methods Six coated and six uncoated enFlow cartridges were used. A solution of 10% propylene glycol and 90% distilled H2O was infused into each heating cartridge at flow rates of 2, 10, 50, 150, and 200 ml/min. The infused fluid temperature was set at 4°C, 20°C, and 37°C. Output temperature was recorded at each level. Data for analysis was derived from 18 runs at each flow rate (six cartridges at three temperatures). Results The parylene coated fluid warming cartridge delivered very stable output of 40°C temperatures at flow rates of 2, 10, and 50 ml/min regardless of the temperature of the infusate. At higher flow rates, the cartridges were not able to achieve the target temperature with the colder fluid. Both cartridges performed with similar efficacy across all flow rates at all temperatures. Conclusions At low flow rates, the parylene coated enFlow cartridges was comparable to the original uncoated cartridges. At higher flow rates, the coated and uncoated cartridges were not able to achieve the target temperature. The parylene coating on the aluminum heating blocks of the new enFlow intravenous fluid warmer does not negatively affect its performance compared to the uncoated model.

The cover story of this issue was "An Invitation" by Howard L. Wolfman, General Chairman, 1972 EMC Symposium. He asks: "What is one of the major activities or benefits which you may receive while belonging to Group-EMC?" His answer was "Attending the Annual Symposium!" "As Chairman of the 1972 EMC Symposium, it is my pleasure to invite, or should I say -strongly request -you to attend this year's Symposium, July 18-20, in Arlington Heights, Illinois. Regardless of your background and degree of current involvement in EMC, you will profit from attending the technical sessions and exhibits. The Group-EMC organization will also profit in several ways from your attendance: (1) as an indication to the world of the support which exists within our Group; (2) monetary support from your registration fee; and (3) an indication to the exhibitors (which form our financial base of support) that their investment is indeed worthwhile."
