It was the replacement of the DC08, and to all intents and purposes is virtually the same in appearance and design as the DC08. DC19T2 Origin no image: 2009: Same as DC19, but improved so that the brushbar can pick up on carpets and on hard floors. This model also used a plastic telescopic rod instead of the metal one found on the original DC19 ...
Dyson Limited, d.b.a Dyson, is a Singaporean–British multinational technology company. [7] Founded in 1991 by James Dyson in Malmesbury , England, the company designs and manufactures household appliances such as vacuum cleaners , air purifiers , hand dryers , bladeless fans , heaters , hair dryers , and lights.
Only the hose and cleaning head need be carried from room to room, and the hose is commonly 8 m (25 ft) long, allowing a large range of movement without changing vacuum inlets. Plastic or metal piping connects the inlets to the central unit. The vacuum head may be unpowered, or have beaters operated by an electric motor or by an air-driven turbine

The Douglas DC-8 was an American piston-engined airliner project by Douglas Aircraft.A concept developed more than a decade before the DC-8 jetliner, the piston-engined DC-8 was to have propellers in the tail, an idea first used at Douglas by Edward F. Burton on a fighter project. [1]
The Douglas DC-8 (sometimes McDonnell Douglas DC-8) is an early long-range narrow-body jetliner designed and produced by the American Douglas Aircraft Company.Work began in 1952 towards the United States Air Force's (USAF) requirement for a jet-powered aerial refueling tanker.
The Feynman diagrams are much easier to keep track of than "old-fashioned" terms, because the old-fashioned way treats the particle and antiparticle contributions as separate. Each Feynman diagram is the sum of exponentially many old-fashioned terms, because each internal line can separately represent either a particle or an antiparticle.
The Schwinger–Dyson equations (SDEs) or Dyson–Schwinger equations, named after Julian Schwinger and Freeman Dyson, are general relations between correlation functions in quantum field theories (QFTs).
