a) A tube showing the imaginary lamina. b) A cross section of the tube shows the lamina moving at different speeds. Those closest to the edge of the tube are moving slowly while those near the center are moving quickly. Assume the liquid exhibits laminar flow. Laminar flow in a round pipe prescribes that there are a bunch of circular layers ...
Often vacuum-tube computers made extensive use of solid-state ("crystal") diodes to perform AND and OR logic functions, and only used vacuum tubes to amplify signals between stages or to construct elements such as flip-flops, counters, and registers. The solid-state diodes reduced the size and power consumption of the overall machine.
Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]
Boris Grabovsky (1901–1966), Russia – cathode commutator, an early electronic TV pickup tube; Bette Nesmith Graham (1924–1980), U.S. – Correction fluid, Liquid Paper; Iréne Grahn (1945–2013), Sweden – finger joint support for patients with rheumatoid arthritis; Hans Christian Gram (1853–1938), Denmark / Germany – Gram staining ...
A gastric feeding tube (G-tube or "button") is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition. One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically. The position of the endoscope can be visualized on the outside of the person's abdomen ...
New York State Correction Officers have peace officer status statewide under Criminal Procedure Law § 2.10; this authorizes them: The power to make warrantless arrests pursuant to Criminal Procedure Law § 140.25 [ 51 ]
The lower prism uses one total internal reflection, followed by a second reflection on the bottom surface to direct the beam into the second Schmidt prism. This second reflection in the lower prism happens at less than the critical angle, therefore the Schmidt–Pechan prism requires a reflective coating for this surface to be usable in ...
The Eustachian tube (/ j uː ˈ s t eɪ ʃ ən /), also called the auditory tube or pharyngotympanic tube, [1] is a tube that links the nasopharynx to the middle ear, of which it is also a part. In adult humans, the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter. [ 2 ]
