The river twisted and shrank above the beaver ponds. It neared a mountain. It was small and quiet here, full of snake-bends, oxbows and small cutthroat trout. It entered a grove of virgin Sitka spruce, and the hoof cut-trail entered in beside it. … The grove was like a vast lodge, barked pillars rising to a high mosaic of green and black and sky. A watery light filtered down, as if through stained glass. In the center of the lodge was a hollow, bordered by sword ferns and fallen logs. In the bottom of the hollow was a broad, rocky bowl eerily paved with mosshaired, head-sized stones. Among the stones was a quiet spring. And from the spring brimmed the water, old and clean and untiring. I had reached the source of the Tamanawis. 相似文献

Mild hypothermia, induced by experimental immersion of ten subjects in cold water, distorted the decay curve of breath ethanol of intoxicated subjects by as much as 22% while not altering overall ethanol clearance rate. The results provide in vivo verification of the in vitro temperature correction factor of 6.8% X degrees C-1, and support previous recommendations that temperature monitoring be included in procedures for breath-ethanol testing. We recommend that mouth temperature be obtained before breath sampling to screen for abnormal body temperature and to allow for potential use of a temperature correction factor. This modification to existing analytical procedures would help to optimize the reliability of breath-ethanol analysis in predicting blood-ethanol concentration. 相似文献

This article examines the role of federal agency budget officers and their responsibilities from the author's own perspective and experience. The article suggests that it is inadequate to standardize the role of an agency budget oficer other than that used by the agency head to determine if he or she is satisfied with the budget processes in the agency. 相似文献

Coronary artery vasculitis is a well-recognized complication of polyarteritis nodosa and is occasionally seen in other forms of systemic vasculitis. However, involvement of the major epicardial coronary arteries leading to myocardial infarction and death is uncommon. Isolated coronary arteritis is even more rare. We report three cases of sudden death due to myocardial ischemia associated with arteritis of the major coronary arteries. All three decedents were previously healthy young to middle-aged men who had died suddenly after complaints of chest pain and shortness of breath. The autopsy findings and differential diagnoses are presented. Such cases are of particular interest to the medical examiner because of the sudden, unexpected nature of the deaths. An approach to the correct diagnosis is discussed. 相似文献
