U uvodu članka opisan je planinski masiv Himalaja, a u sljedećem poglavlju njegov nastanak. U nastavku su opisani počeci uporabe trigonometrijskih mreža u Europi te uporaba tih mreža u Indiji, gdje ...je G. Everest ostvario veliko djelo. Kad je A. S. Waugh, nasljednik G. Everesta, došao s trigonometrijskom mrežom do Himalaje, odredio je i visinu najvišeg vrha, Mt. Everesta, trigonometrijskim načinom, mjerenjem vertikalnih kutova samo u smjeru prema Mt. Everestu. Poslije se nastojalo što točnije odrediti visinu toga najvišega vrha na Zemlji uvođenjem suvremenih mjerenja. Ime Mt. Everest uvedeno je 1865. godine na prijedlog A. S. Waugha. Za taj vrh postoje i drugi nazivi domicilnog stanovništva u Kini i Nepalu. Na kraju su opisani počeci alpinističkih uspona na Mt. Everest.
The radiation exposure rates were measured inside and outside a private house in the Tibetan Autonomous Region of China. As far as seen from the cosmic ray exposure rate and the gamma ray exposure ...rate, the indoor exposure rates can be classified into 3 groups: the 2nd floor, entrance to the 1st floor and in the rest of the 1st froor. In the 1st group, the mean cosmic ray exposure rate was 4.079nC/kg/h (15.81μR/h) and the mean gamma ray exposure rate was 4.515nC/kg/h (17.50μR/h) .In the 3rd group, the mean cosmic ray exposure rate was 2.740nC/kg/h (10.62μR/h) and the mean gamma ray exposure rate was 5.284nC/kg/h (20.48μR/h) .The reason why the cosmic ray exposure rate in the 3rd group is lower than in the 1st group is believed to be that cosmic rays are cut off by the construction materials. The reasons why the gamma ray exposure rate in the 3rd group is higher than in the 1st group are believed to be that the 3rd group is nearer to the ground than the 1st group and the stones of which the 1st floor walls are made have a higher concentration of natural radionuclides than the earth of which the 2nd floor walls are made. Both the cosmic ray exposure rate and the gamma ray exposure rate in the 2nd group are between those of the 1st group and the 3rd group. Futhermore, the authors calculated the air absorbed dose rates inside and outside a Tibetan private house and compared them with those of private houses in the world.
For centuries, mountains have given rise to legends about supernatural beings such as the Yeti of the Himalayas. The legend of the Yeti was enhanced by the finding of footprints in the Menlung Basin ...during the 1951 Everest reconnaissance expedition. This report provides a possible explanation of the Menlung footprints based on developmental abnormalities, physiology, and pathology of the foot.
The use of supplemental oxygen on Mt. Everest is now commonplace. From 1990 to 2006, more than 95% of those summiting the mountain did so using supplemental oxygen at some point during their ascent. ...The open circuit systems currently in use can be traced back to the device first used by George Finch on Mt. Everest in 1922. Wearing equipment weighing 33 lb (15 kg), Finch and his colleague Geoffrey Bruce set a world altitude record by reaching a height of 27,250 ft (8175 m). However, it would be with a lighter system weighing just 22 lb (10 kg) that Sir Edmund Hillary and Tenzing Norgay made the first ascent of the mountain in 1953. In the years since then considerable improvements in weight, comfort, and efficiency have been made; however, the original "open" principles first used by Finch almost a century ago still remain steadfastly in place.
Acute and subacute altitude exposure tests were performed on 38 members of Himaraya expeditions in a laboratory with low atmospheric pressure, and EEG changes and reactions of physiological acute ...adaptation were examined in order to obtain informations that will prove of help in preventing hypobaropathy and in health management in high mountain climbing. Meanwhile, EEG during climbing Mt. Everest were recorded and analyzed using power spectrum to compare with the results of above-mentioned tests. An inquiry was also made into the effct of a long-term sojourn at altitudes on brain function which has remained almost unclarified so far. 1. Acute exposure to the altitude up to 4, 000m was attended with little change in EEG pattern, while at the altitude around 6, 000m slow waves were observed on EEG in all subjects, suggesting marked depression of brain function. 2. EEG changes caused by long-term exposure to altitudes (Mt. Everest climbing) were marked primarily by slowing of alpha waves with a subsequent appearance of slow waves. However, these changes varied grossly in severity with different indivisuals, depending upon the physiological compensatory function of the whole boby. 3. A follow-up EEG study demonstrated that a conspicuous delta-bursts occurred on activated hyperventilation following a long stay in altitudes, suggesting that the effects of long-term exposure to high altitude on brain function may persist for a certain period of time. 4. Hypoxic symptoms observed in high altitude environment were attributable to the disruption of various physiological compensatory functions and EEG could serve as an index for the evaluation of impairment of brain function. 5. It may be concluded that it is difficult to evaluate an aptitude for climbing high mountains only from these results.
