In forestry, it is still common to plant the seedlings of and cultivate Norway spruce (Picea abies L. Karst) at lower altitudes; however, climatic change that has been occurring increases evaporative demands in these areas. As a result, evidently suffers from drought, withers loses its power grow, thus, influencing stem thickness tree-height growth, as well biomass production. Therefore, growth...

This review describes adverse outcomes in pregnancy after brief, intermittent, or permanent residence at high altitudes. Review of literature shows that congenital malformations rates are higher at high altitudes. Additionally, rates of stillbirths, small size for gestational age, and preeclampsia are increased in populations living at high altitudes and are associated with high maternal hemogl...

objective: this study is an attempt to examine the anti apoptotic effects of bio on rat msc culture. materials and methods: rat marrow primary cell culture was established and exposure groups were defined; cultures with 0.01, 0.1, 1 μm bio. cells cultured without bio treatment were used as controls. during culture expantion, the average doubling time, as an index of the rate of cell growth, wer...

BACKGROUND Age related bone loss is widely accepted as related to decreased serum levels of circulating sex hormones. Epidemiological data also show distal radius fractures in men to be a sensitive marker of bone fragility. The aim of this study was to assess if men with a history of distal radius fracture have lower bone mass density (BMD), lower free androgen index (FAI), lower total testoste...

Saving fuel by splitting a flight mission with an intermediate stop for refuelling is described the concept of operations. This can also be beneficial to climate impact aviation, if level and airport are selected accordingly. study aims estimate mitigation potential implementation climate-optimised operations European long-haul flights compare it fuel-optimal For this purpose, consumption emiss...

BACKGROUND Assessment of malaria endemicity at different altitudes and transmission intensities, in the era of dwindling vector densities in the highlands, will provide valuable information for malaria control and surveillance. Measurement of serum anti-malarial antibodies is a useful marker of malaria exposure that indicates long-term transmission potential. We studied the serologic evidence o...

MF radar wind measurements in the mesosphere and lower thermosphere over Poker Flat, Alaska (65.1 N, 147.5 W) are used to study the features of mean winds and solar tides. Continuous observation with the newly installed radar is in progress and in the present study we have analyzed a database of the first 27 months (October 1998–December 2000) of observation. The observed mean wind climatology ...
