A 26-year-old Korean male started to climb Mt. Fuji, the highest mountain in Japan (3776 m above sea lever [ASL]). He began coughing at the seventh station of the mountain (2700 m ASL) but continued to climb. When he reached the top of the mountain, he felt dyspnea, chest pain and headache. Even after descending the mountain, these symptoms did not improve. On arriving back at the seventh stati...

equilibrium-line altitudes (elas) of former glaciers in the zardkuh mountain of the zagros mountain range were reconstructed from glacial-geologic data on former ice limits by using various methods. in the study area various types of glacial landforms such as outwash fans, moraines and well developed glacial cirques are observed. the results suggest that ela were depressed 1433 m below to prese...

the research was carried out to study the effect of provenance variation on stem length, stem biomass, root biomass and survival ofcaucasian oak (quercus macranthera) seedlings. the seeds were collected from several seed sources grown in an altitude range of 1800-2000 m a.s.l in alborz mountain, both from the northern facing slope, kordkoy and chichal, and from the southern facing slope, roudba...

Introduction The Islamic Republic of Iran (Figure 1) has an area of 1,648,000 km 2 and a population of 65 million people (1995 estimate). The country has arid and semiarid climates and the occurrence of rainfall is unreliable, with a coefficient of variation as high as 70%. The average annual precipitation over the country is around 250 mm. Two mountain ridges, the Alborz and Zagros (Figure 1),...

The geographic distribution of Astragalus (Fabaceae) in Iran was analyzed using a database of 7606 georeferencedobservations. Astragalus occurs in all provinces of Iran, but 88% ofthe observations are in five provinces including Tehran, West-Azerbaijan, Esfahan, Kordestan, and Khorasan-e Razavi.Most species are rare and narrowly endemic: Thelargest distance between two observations of the same ...

mountains and trees have many similarities. in this way, simorgh of shahnameh shifts from the tree of vispobish to alborz mountain. if simorgh has spiritual existence in avesta, a devilish side has been added to it in shahnameh. in avesta, it lives on a tree, but in shahnameh we find him on alborz mountain. all the researches done on shahnameh and iranian mythology did not pay any attention to ...

Microbial biomass phosphorus (MBP) is one of the most active forms of phosphorus (P) in soils. MBP plays an important role in the biogeochemical P cycle. To explore MBP distribution and its relationship with other factors, the MBP and rhizosphere soil P concentrations and fractions in six vegetation zones on the eastern slope of Gongga Mountain in SW China were investigated. The MBP distributio...

BACKGROUND The presence of the recently introduced primary dengue virus vector mosquito Aedes aegypti in Nepal, in association with the likely indigenous secondary vector Aedes albopictus, raises public health concerns. Chikungunya fever cases have also been reported in Nepal, and the virus causing this disease is also transmitted by these mosquito species. Here we report the results of a study...
