Push–pull Output
A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance both the load capacity and switching speed. Push–pull outputs are present in TTL and CMOS digital logic circuits and in some types of amplifiers, and are usually realized by a complementary pair of transistors, one dissipating or ''sinking'' current from the load to ground or a negative power supply, and the other supplying or ''sourcing'' current to the load from a positive power supply. A push–pull amplifier is more efficient than a single-ended "class-A" amplifier. The output power that can be achieved is higher than the continuous dissipation rating of either transistor or tube used alone and increases the power available for a given supply voltage. Symmetrical construction of the two sides of the amplifier means that even-order harmonics are cancelled, which can re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Perfusion
Push–pull perfusion is an in vivo sampling method most commonly used for measuring neurotransmitters in the brain. Developed by J.H. Gaddum in 1960, this technique replaced the cortical cup technique for observing neurotransmitters. The advent of concentric microdialysis probes in the 1980s resulted in push-pull sampling falling out of favor, as such probes require less monitoring, and are less invasive than the higher flow rate push-pull probes (>10 microliter/min), which could result in lesions if flow is unbalanced. With the advent of microfluidics and miniaturized probes, low-flow push–pull sampling was developed in 2002. By using flow rates of ~50 nL/min, this technique minimizes tissue damage while providing finer spatial resolution than microdialysis Microdialysis is a minimally-invasive sampling technique that is used for continuous measurement of free, unbound analyte concentrations in the extracellular fluid of virtually any tissue. Analytes may include endo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Strategy
The business terms ''push'' and ''pull'' originated in logistics and supply chain management, but are also widely used in marketing and in the hotel distribution business. Walmart is an example of a company that uses the push vs. pull strategy. Supply-chain management Complete definition There are several definitions on the distinction between push and pull strategies. Liberopoulos (2013) identifies three such definitions: # A pull system initiates production as a reaction to present demand, while a push system initiates production in anticipation of future demand. # In a pull system, production is triggered by actual demands for finished products, while in a push system, production is initiated independently of demands. # A pull system is one that explicitly limits the amount of WIP that can be in the system, while a push system has no explicit limit on the amount of WIP that can be in the system. Other definitions are: * ''Push'': As stated by Bonney et al. (1999) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Agricultural Pest Management
Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. For example, cereal crops like maize or sorghum are often infested by stem borers. Grasses planted around the perimeter of the crop attract and trap the pests, whereas other plants, like ''Desmodium'', planted between the rows of maize, repel the pests and control the parasitic plant ''Striga''. Push–pull technology was developed at the International Centre of Insect Physiology and Ecology (ICIPE) in Kenya in collaboration with Rothamsted Research, UK. and national partners. This technology has been taught to smallholder farmers through collaborations with universities, NGOs and national research organizations. How push–pull works Push–pull technology involves use of behaviour-modifying stimuli to manipulate the distribution and abundance of stemborers and beneficial insects for management of stemborer pests. It is based o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pushmi-pullyu
This is a list of characters from the ''Doctor Dolittle'' series of children's books by Hugh Lofting and movies based on them. Most of the characters were introduced in the first book, the 1920 novel ''The Story of Doctor Dolittle''. Humans Doctor Dolittle ;Portrayed by: * Rex Harrison (1967) * Eddie Murphy (1998, 2001) * Robert Downey Jr. (2020) Doctor John Dolittle is an English physician who became a doctor for animals after his parrot, Polynesia, taught him to speak animal languages. He lives in the fictional town of Puddleby-on-the-Marsh in England's West Country, along with his many animal friends. He has very few human friends and spends most of his time treating animals, travelling the world with his animals and conducting research into new animals and new forms of animal languages. He is portrayed by Rex Harrison in the 1967 film ''Doctor Dolittle'', Eddie Murphy in ''Dr. Dolittle'' (1998) and '' Dr. Dolittle 2'' ( 2001), and by Robert Downey Jr. in '' Dolittle'' (20 ...

Hans Hofmann
Hans Hofmann (March 21, 1880 – February 17, 1966) was a German-born American painter, renowned as both an artist and teacher. His career spanned two generations and two continents, and is considered to have both preceded and influenced Abstract Expressionism.de la Croix, Horst and Richard G. Tansey. ''Gardner's Art Through the Ages'', 7th Ed., New York: Harcourt Brace Jovanovich, 1980, p. 857-8. Born and educated near Munich, he was active in the early twentieth-century European avant-garde and brought a deep understanding and synthesis of Symbolism, Neo-impressionism, Fauvism, and Cubism when he emigrated to the United States in 1932.Chipp, Herschel B. ''Theories of Modern Art'', Berkeley & Los Angeles: University of California Press, 1968, p. 511–2. Hofmann's painting is characterized by its rigorous concern with pictorial structure and unity, spatial illusionism, and use of bold color for expressive means.Seitz, William C.

(Do The) Push And Pull
"(Do The) Push and Pull (Part 1)" is a 1970 single on Stax Records by singer Rufus Thomas. The song was written by Thomas, and the recording was arranged by Carl Hampton, and produced by Al Bell and Tom Nixon. This was the first and only number-one song for Thomas, who had first hit the R&B chart in 1953. The song was at the top of the ''Billboard'' Best Selling Soul Singles The Hot R&B/Hip-Hop Songs chart ranks the most popular R&B and hip hop songs in the United States and is published weekly by ''Billboard''. Rankings are based on a measure of radio airplay, sales data, and streaming activity. The chart had 100 p ... chart for two weeks in February 1971.
