The heart rate response to exercise was studied in 17 normal subjects before, during and after a 21-day Himalayan trek to 5490 m. The group were fitter before the trek when compared to normal subjects of a similar age (P less than 0.001) having a lower heart rate response to exercise for their lean body mass. The trek significantly increased the 'fitness' of the group as a whole (P less than 0....

Keratinous horn sheaths of the extinct Harrington's mountain goat, Oreamnos harringtoni, were recovered at or near the surface of dry caves of the Grand Canyon, Arizona. Twenty-three separate specimens from two caves were dated nondestructively by the tandem accelerator mass spectrometer (TAMS).

In this article, we analyze the application of options contract in the special commodity supply chain such as fresh agricultural products. This problem is discussed from the point of the retailer. When spot market and future market are both available, we discuss how the retailer chooses the optimal production. Furthermore, overconfidence is introduced to the supply chain of the fresh agricultur...

Lamport’s Happened-before relation is fundamental to coordinating actions in asynchronous systems. Its role is less dominant in synchronous systems, in which bounds are available on transmission times over channels. This paper initiates a study of the role that time bounds play in synchronous systems by focusing on two classes of problems: Ordered Response, in which a triggering event must be f...

INTRODUCTION The chemical industry is a much safer place to work than many industries with fewer inherent hazards. Nevertheless, almost all the accidents that have occurred need not have occurred. Most of them have happened before and have been described in published reports. Someone knew how to prevent them even if the people on the job at the time did not. There is something seriously wrong w...

BACKGROUND Rhodiola crenulata (R. crenulata) is widely used to prevent acute mountain sickness in the Himalayan areas and in Tibet, but no scientific studies have previously examined its effectiveness. We conducted a randomized, double-blind, placebo-controlled crossover study to investigate its efficacy in acute mountain sickness prevention. METHODS Healthy adult volunteers were randomized t...

BACKGROUND Altitude illness results from hypobaric hypoxia at altitudes higher than 2500 meters above sea level. To determine whether vital signs can be used as predictors for severe acute mountain sickness, we carried out a prospective observational study. METHODS A cohort of 90 individuals (male/female ratio: 2; age: 13 - 65 years) in a mountain hotel's clinic at 3450 meters in Iran were st...
