A 55-year-old man was found unconscious with ventricular fibrillations at his working place near a power press. CPR was successful. After three weeks of intensive care the patient died of ischemic brain damage. The first suspected diagnosis of myocardial infarction was revised when typical current marks were detected on both palms. At the working place the top of a lubricating grease container was found to be energized due to a technical damage: There is a round, multiple-pole plug mounted upon the container top the proper orientation of which is coded by a set of five plastic nipples. All the nipples had been abraded by longlasting mechanical stress, so that the plug could be connected in a variety of possible orientations. In actual fact, the incorrect orientation caused a voltage of up to 240 V to the container top. 相似文献

This is another in a series of technical articles describing Social Security Administration sample files and statistical systems. The focus of this article is the 10-percent sample file that provides program and demographic information on Social Security beneficiaries under the Old-Age, Survivors, and Disability Insurance program. The article explains the contents and availability of the 10-percent sample and presents several statistical tabulations as examples of the wide variety of data that can be developed from the file. 相似文献

The use of salt for deicing roads results in costs estimated at more than $800 per ton—including the costs of repair and maintenance of roads and bridges, vehicle corrosion costs, and loss of aesthetic value through roadside tree damage. Additionally, there are probable health costs related to elevated sodium levels in drinking water. The new Surface Transportation Act of 1991 appears to replace the previous federal funding policy that was biased against the use of calcium magnesium acetate (CMA) with a new subsidy for its purchase that may lead to inefficient overuse. 相似文献
