In the words of the space historians Murray and Cox, Kraft "set the tone for one of the most striking features of Flight Operations: unquestioning trust not of superiors by subordinates, but the other way around".
Although there are strong links in birds and mammals between brain lateralization and behavioural lateralization (in pigeons, [10] [11]; in chicks, [9]), functional wing symmetry is critical for anatomical, biomechanical, and energetic features of flight [27] [28].
The PET component of the system features time-of-flight technology, an axial field of view of 18 cm, 9 cm overlap between bed positions and a reconstructed isotropic spatial resolution of about 5.5 mm.
With airlines examining every feature of a flight to see if it can be sold separately — what the industry calls unbundling — Mr. Harteveldt said he could see a day when the carriers might sell membership in the elite tiers of their frequent-flier programs, perhaps letting passengers purchase an upgrade from silver to gold status.
Another interesting feature of insect flight is the body tilt.
This characteristic feature of insect flight has been interpreted as a strategy to facilitate the gathering of spatial information during intersaccadic intervals (Egelhaaf et al., 2012).
With jet fuel costing 84percentt more than it did a year ago, major airlines are raising fares and re-examining every feature of their flights, eliminating those they cannot afford.
Many insect species undertake long-range, high-altitude nocturnal migrations, but one characteristic feature of these flights, at least in the larger species (such as moths or grasshoppers), has puzzled researchers for over 40 years, namely: how do insects maintain wind-related orientation at altitudes of several hundreds of metres in the dark?
A fundamental feature of time-of-flight mass spectrometry is that the rate of ion arrivals at the detector plate is governed by the Poisson distribution.
