Deformity, in medicine, a major difference in the shape of body part or organ compared to the average shape of that part
Any Caledonian deformation is unclear but the fault zone was reactivated in the Carboniferous as a NW-throwing normal fault with seismic reflection data showing the formation of a half-graben in its hanging wall.
In 1934, Egon Orowan, Michael Polanyi and G. I. Taylor, almost simultaneously realized that plastic deformation could be explained in terms of the theory of dislocations.
The glacier was named by the Advisory Committee on Antarctic Names in 2006 after Andrea Donnellan of the Satellite Geodesy and Geodynamics Systems Group at the Jet Propulsion Laboratory, California Institute of Technology, who was involved from the mid-1990s in research projects involving the use of GPS in studies of earth crustal deformation in Southern California and also in Antarctica.
He believed one was from the Quaternary period, and the other had ritual deformation in a manner similar to the skulls of the Aymara people of the Andes and Altiplano.
Although the present topography of the range and adjoining basins is controlled by extension during rifting in the last 10 million years, faults within the range also record deformation during the Laramide orogeny, between 85 and 45 million years ago.
Deformation of the hull is based on the concept of so-called hyper-patches, which are three-dimensional analogs of parametric curves such as Bézier curves, B-splines, or NURBs.
In 1934, Taylor, roughly contemporarily with Michael Polanyi and Egon Orowan, realised that the plastic deformation of ductile materials could be explained in terms of the theory of dislocations developed by Vito Volterra in 1905.
In mathematics, the Iwahori–Hecke algebra, or Hecke algebra, named for Erich Hecke and Nagayoshi Iwahori, is a one-parameter deformation of the group algebra of a Coxeter group.
Although both FitzGerald and Lorentz alluded to the fact that electrostatic fields in motion were deformed ("Heaviside-Ellipsoid" after Oliver Heaviside, who derived this deformation from electromagnetic theory in 1888), it was considered an ad hoc hypothesis, because at this time there was no sufficient reason to assume that intermolecular forces behave the same way as electromagnetic ones.
He proved Schlessinger's theorem about representable functors of Artinian algebras and introduced Lichtenbaum–Schlessinger functors in deformation theory.
Yet Lorence G. Collins does not agree with the assumption of the K-feldspar being primary magmatic and the myrmekite being formed due to deformation-induced Na-Ca-metasomatism.
The term 'fold' is used in geology when one or more originally flat sedimentary strata surfaces are bent or curved as a result of plastic (i.e. permanent) deformation.
(The oldest illustration of this may be the realization of Eratosthenes in the ancient world that a flat earth was deformable to a spherical earth, with deformation parameter 1/R⊕.)
