The Edersee Dam in Hesse, Germany. A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.
Quizlet was founded in 2005 by Andrew Sutherland as a studying tool to aid in memorization for his French class, which he claimed to have "aced". [ 6 ] [ 7 ] [ 8 ] Quizlet's blog, written mostly by Andrew in the earlier days of the company, claims it had reached 50,000 registered users in 252 days online. [ 9 ]
Alien hand syndrome (AHS) or Dr. Strangelove syndrome [1] is a category of conditions in which a person experiences their limbs acting seemingly on their own, without conscious control over the actions. [2] There are a variety of clinical conditions that fall under this category, most commonly affecting the left hand. [3]
through hand-operated oars, paddles, or poles, or; through the feet with pedals, crankset or treadle. [1] While most human-powered watercraft use buoyancy to maintain their position relative to the surface of the water, a few, such as human-powered hydrofoils and human-powered submarines, use hydrofoils, either alone or in addition to buoyancy.
Intelligence is, along with the more precise concept of sapience, used to describe extraterrestrial life with similar cognitive abilities as humans. Another interchangeable term is sophoncy, being wise or wiser, first coined by Karen Anderson and published in the 1966 works by her husband Poul Anderson.
An artificial reef (AR) is a human-created freshwater or marine benthic structure. [1] Typically built in areas with a generally featureless bottom to promote marine life , it may be intended to control erosion , protect coastal areas, block ship passage, block the use of trawling nets, [ 2 ] support reef restoration, improve aquaculture , or ...
Human languages conform to a Zipfian distribution, while many (but not all) other data sequences do not. It has been proposed that an alien language also might conform to such a distribution. [30] When displayed in a log-log graph of frequency vs. rank, this distribution would appear as a somewhat straight line with a slope of approximately -1.
The injection of supercritical CO 2 will change the stresses in the reservoir as it expands, causing potential failure on nearby faults. Injection of fluids also increases the pore pressures in the reservoir, triggering slip on existing rock weakness planes. The latter is the most common cause of induced seismicity due to fluid injection. [12]
