Birds living at high altitude (>3,000 meters) are not only able to cope with reduced oxygen availability due to hypobaria, but they are also able to achieve one of the most metabolically costly form of locomotion at these altitudes: flight. To perform such a metabolically demanding activity, in addition to energetically expensive daily tasks such as foraging, predator escape, and reproduction, all in oxygen limited (hypoxic) conditions, means that high altitude birds must enhance oxygen supply to maintain oxygen homeostasis. The primary means of increasing oxygen supply is increasing ventilati

Currently deployed unmanned rotorcraft rely on preplanned missions or teleoperation and do not actively incorporate information about obstacles, landing sites, wind, position uncertainty, and other aerial vehicles during online motion planning. Prior work has successfully addressed some tasks such as obstacle avoidance at slow speeds, or landing at known to be good locations. However, to enable autonomous missions in cluttered environments, the vehicle has to react quickly to previously unknown obstacles, respond to changing environmental conditions, and find unknown landing sites.

Athletes commonly use altitude exposure in an attempt to improve their aerobic performance at sea level. Altitude exposure enhances erythropoiesis and iron-dependent oxidative and glycolytic enzyme production, for this reason, athletes must maintain a healthy iron balance at altitude. A negative iron balance at altitude may limit such physiological adaptations, potentially reducing the performance benefits of altitude exposure.

However, this blanket-treatment approach is not suitable in all cases and a more personalised approach is required.

As humans ascend to high altitude, the resulting hypobaric hypoxia necessitates adaptation in order continue functioning. Whilst much is known about changes that facilitate a restoration of systemic oxygen delivery during ascent, less is know about alterations in the peripheral microcirculation and how these affect acclimatisation and performance at altitude. The limit of human adaptation to hypoxia is also undefined. Using data derived from a number of studies conducted on healthy volunteers at high altitude, this thesis explores changes in skeletal muscle oxygenation and sublingual microcirc

Changes to species distributions involve demographic processes that occur over generations and affect allele frequencies within populations, leading to patterns of genetic restructuring. The specific genetic structuring patterns that will be observed as a consequence depend on explicit geographical features, such as topography and latitude. Over the first decades of phylogeography, the effect of climate history and geography on species genomes was examined at low resolution with DNA sequences and other traditional molecular markers. However, During the last five years it has become feasible to

This paper deals with the estimation of altitude of the drone for which the sensors like ultrasonic, barometric pressure sensors and their characteristics plays a major role. To  estimate the altitude of the drone, we used the matlab software with Simulink. apart from the software and hardware description, we discuss several issues regarding the equipment,abilities and performance of the drone.
