purpose headache at altitudes has had an incidence of 25-62% through many related studies. many reasons are identified concerning headache at altitudes such as acute mountain sickness (ams), sinus headache, migraine, tension type headache, and frontal tension headache. this study tried to compare different types of headache among trekkers on mount damavand, a 5671m mountain, iran, to find their...

A mountain-top-to-mountain-top optical communications demonstration was conducted between the JPL Table Mountain Facility (TMF), Wrightwood, California, and Strawberry Peak (SP), Lake Arrowhead, California, during the months of August and September of 2000. The link was nearly horizontal at an altitude of 2 km and spanned a range of 46.8 km. A 780-nm multibeam beacon broadcast from TMF was rece...

The Hospital had hardly been opened when the second world war began. During this period the building, though struck by bombs on two occasions in 1940 and heavily blasted by a land mine in April 1941, continued to serve its functions throughout. So, too, the School functioned vigorously during the war, even though the preclinical students had been evacuated in the early years, at first to Glasgo...

The Ferris Mountain Wilderness Study Area (WSA) is one of 42 WSAs in Wyoming managed by the Bureau of Land Management (BLM) as part of the National Landscape Conservation System (NLCS). To date, no WSA in Wyoming has been elevated to Wilderness Area status under the NLCS. Information about the characteristics that make a WSA eligible for Wilderness Area designation is needed during the evaluati...

Compared with other African apes, eastern gorillas (Gorilla beringei) have been little studied genetically. We used analysis of autosomal DNA genotypes obtained from non-invasively collected faecal samples to estimate the evolutionary histories of the two extant mountain gorilla populations and the closely related eastern lowland gorillas. Our results suggest that eastern lowland gorillas and m...

Minerals are critical to an individual's health and fitness, and yet little is known about mineral nutrition and requirements in free-ranging primates. We estimated the mineral content of foods consumed by mountain gorillas (Gorilla beringei beringei) in the Bwindi Impenetrable National Park, Uganda. Mountain gorillas acquire the majority of their minerals from herbaceous leaves, which constitu...

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). Both the TAMS and the conventional dates indicate that Harrington's mountain goat occupied the Grand...

In her article "Aesthetics in Gao's Soul Mountain" Mabel Lee analyses Nobel Laureate 2000 Xingjian Gao's aesthetics. Transnational conglomerates today control the book industry from publishing house to bookshop and through aggressive market strategies they exert considerable influence on readers. Nonetheless, there are writers who refuse to capitulate to market demands and seek only to actualiz...

Fire occurs relatively frequently in beech (Nothofagus) forest in drought prone eastern areas of the South Island, New Zealand. Because beech is poorly adapted to fire, and is slow to regenerate, forest is normally replaced by scrub or grassland. Seeding was investigated as a means of restoring mountain beech (N. solandri var. cliffortioides) forest after fire destroyed 300 ha of forest at Mt. ...
