Pump
A pump is a device that moves fluids (liquids or gases), or sometimes Slurry, slurries, by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy. Mechanical pumps serve in a wide range of applications such as Water well pump, pumping water from wells, aquarium filtering, pond filtering and Water aeration, aeration, in the car industry for Water cooling, water-cooling and fuel injection, in the energy industry for Pumping (oil well), pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and Penile implant, penile prosthesis. When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a ''multi-stage pump''. T ...

Breast Pump
A breast pump is a mechanical device that Lactation, lactating women use to milking, extract milk from their breasts. They may be manual devices powered by hand or foot movements or automatic devices powered by electricity. Breast pumps come in several varieties to suit different needs of mothers. Manual pumps, operated by hand, are portable and quiet, making them suitable for occasional use. Electric pumps, powered by batteries or mains electricity, offer increased efficiency and are often preferred for regular expression. Hospital-grade breast pumps are the most powerful, designed for frequent, heavy-duty use, particularly beneficial for mothers of premature infants or those with lactation challenges. Many modern breast pumps incorporate adjustable suction levels and cycling speeds to mimic a baby's natural feeding patterns, aiming to optimize comfort and milk production for the user. Breast pumps have been used since antiquity, with evidence suggesting their use in civilizations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumping (audio)
In sound recording and reproduction, and music, pumping or gain pumping is a creative misuse of compression, the "audible unnatural level changes associated primarily with the release of a compressor." There is no ''correct'' way to produce pumping, and according to Alex Case, the effect may result from selecting "too slow or too fast...or too, um, medium" attack and release settings.Case, Alex (2007). ''Sound FX'', p.160. Focal Press. Cited in Hodgson (2010), p.81. The technique is common in rock and electronic dance music. Examples include Phil Selway's (Radiohead) drum track on " Exit Music (For a Film)", electro percussion loop in Radiohead's "Idioteque", Benny Benassi's "Finger Food", and the ride cymbals on Portishead's "Pedestal". Side-chain pumping is a more advanced technique using a compressor's ''side-chain'' feature which, "uses the amplitude envelope (dynamics profile) of one track as a trigger for a compressor used in another track." When the amplitude of a note o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pumping (oil Well)
In the context of oil wells, pumping is a routine operation involving injecting fluids into the well. Pumping may either be done by rigging up to the kill wing valve on the Xmas tree or, if an intervention rig up is present pumping into the riser through a T-piece (a small section of riser with a connection on the side). Pumping is most routinely done to protect the well against scale and hydrates through the pumping of scale inhibitors and methanol. Pumping of kill weight brine may be done for the purposes of well kills and more exotic chemicals may be pumped from surface for cleaning the lower completion or stimulating the reservoir (though these types are jobs are more frequently done with coiled tubing for extra precision). Importance of knowing quantity Work involving wells is fraught with difficulties as there is often very little information about the real time condition of the completion. This lack of knowledge also covers potential damage and even loss of well integr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In the theory of formal languages, the pumping lemma may refer to: *Pumping lemma for regular languages, the fact that all sufficiently long strings in such a language have a substring that can be repeated arbitrarily many times, usually used to prove that certain languages are not regular *Pumping lemma for context-free languages, the fact that all sufficiently long strings in such a language have a pair of substrings that can be repeated arbitrarily many times, usually used to prove that certain languages are not context-free * Pumping lemma for indexed languages * Pumping lemma for regular tree languages See also * Ogden's lemma In the theory of formal languages, Ogden's lemma (named after William F. Ogden) is a generalization of the pumping lemma for context-free languages. Despite Ogden's lemma being a strengthening of the pumping lemma, it is insufficient to fully char ...

Gastric Lavage
Gastric lavage, also commonly called stomach pumping or gastric irrigation or gastric suction, is the process of cleaning out the contents of the stomach using a tube. Since its first recorded use in the early 19th century, it has become one of the most routine means of eliminating poisons from the stomach. Such devices are normally used on a person who has ingested a poison or overdosed on a drug such as ethanol. They may also be used before surgery, to clear the contents of the digestive tract before it is opened. Apart from toxicology, gastric lavage (or nasogastric lavage) is sometimes used to confirm levels of bleeding from the upper gastrointestinal tract. It may play a role in the evaluation of hematemesis. It can also be used as a cooling technique for hyperthermic patients. Technique Gastric lavage involves the passage of a tube (such as an ''Ewald tube'') via the mouth or nose down into the stomach followed by sequential administration and removal of small volumes of ...

Optical Pumping
Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion. The technique was developed by the 1966 Nobel Prize winner Alfred Kastler in the early 1950s. Page 56. Optical pumping is also used to cyclically pump electrons bound within an atom or molecule to a well-defined quantum state. For the simplest case of coherent two-level optical pumping of an atomic species containing a single outer-shell electron, this means that the electron is coherently pumped to a single hyperfine sublevel (labeled m_F\!), which is defined by the polarization of the pump laser along with the quantum selection rules. Upon optical pumping, the atom is said to be ''oriented'' in a specific m_F\! sublevel, however, due to the cyclic nature of optical pumping, the bound electron will actually be unde ...

Pump (skateboarding)
Pumping is a skateboarding technique used to accelerate without the rider's feet leaving the board. Pumping can be done by turning or on a transition, like a ramp or quarter pipe.{{cite web , url=https://skateboarding.transworld.net/how-to/basics-ollies/pumping/ , title=Skateboarding 101: How to Pump on Transition and Maintain Speed , date=15 August 2024 When applied to longboards, it is also known as Long distance skateboard pumping or LDP. Pumping is a technique similar to pumping a surfboard. Transition Transition pumping can only be done when there is a slope differential between the front and rear wheels. On a ramp it therefore is only possible at the top and bottom of the slope, but in a pipe it is possible at any height above the flat. The rider should push downward on the truck with the greatest slope under the wheels. On the top of a ramp the front wheels should be pushed, and at the bottom the rear trucks should be pushed. On a pipe the weight should be applied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
