X-ray motion analysis is a technique used to track the movement of objects using X-rays.This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera, allowing for high quality videos sampled many times per second.
Documentary film, shot at 1200 fps, used to study the locomotion of a cheetah. The end of the video shows the methods used for filming. A variety of methods and equipment are used to study animal locomotion: Treadmills are used to allow animals to walk or run while remaining stationary or confined with respect to external observers.
Just as movies, TV, and web videos are to a substantive extent no longer separate technologies, but only variations on common underlying digital themes, so, too, are the X-ray imaging modes, and indeed, the term "X-ray imaging" is the ultimate hypernym that unites all of them, even subsuming both fluoroscopy and four-dimensional CT (4DCT ...
The traits enabled animals to check area on land for safe spots if being chased by a predator in water, as well as being useful for searching for prey items above the water. The water-based lateral line system was used substantially by these aquatic tetrapods to detect danger from predators. [ 2 ]
An Alpine chough in flight at 3,900 m (12,800 ft). Organisms can live at high altitude, either on land, in water, or while flying.Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
Several groups of tetrapods have undergone secondary aquatic adaptation, an evolutionary transition from being purely terrestrial to living at least part of the time in water. These animals are called "secondarily aquatic" because although their ancestors lived on land for hundreds of millions of years, they all originally descended from ...
The Life of Mammals is a nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 20 November 2002.. It is a documentary on the study of the evolution and habits of the various mammal species.
