A slipstream is a region behind a moving object in which a wake of fluid (typically air or water) is moving at velocities comparable to that of the moving object, relative to the ambient fluid through which the object is moving. [1] The term slipstream also applies to the similar region adjacent to an object with a fluid moving around it.
For example, hypermilers using this technique can achieve 75 mpg or more (a 10% increase in efficiency of certain hybrid vehicles). [10] Some sources say that the most common tailgating does not save gasoline even at freeway speeds because one is likely to accelerate and brake so frequently that any aerodynamic savings are lost through the brakes.
Animals will use different gaits for different speeds, terrain, and situations. For example, horses show four natural gaits, the slowest horse gait is the walk, then there are three faster gaits which, from slowest to fastest, are the trot, the canter, and the gallop. Animals may also have unusual gaits that are used occasionally, such as for ...
Most American geography and social studies classrooms have adopted the five themes in teaching practices, [3] as they provide "an alternative to the detrimental, but unfortunately persistent, habit of teaching geography through rote memorization". [1] They are pedagogical themes that guide how geographic content should be taught in schools. [4]
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Slipstream is a literary genre or category of speculative fiction that blends together science fiction, fantasy, and literary fiction, [1] or otherwise does not remain within conventional boundaries of genre and narrative.

Range of the snail Elona quimperiana, an example of a disjunct distribution. In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. [1]
