Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1] [2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3] Movement of rock along the fracture occurs in faults.
A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics. [1] Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic footwalls that are called metamorphic core complexes .
Nearly all faults have some component of both dip-slip and strike-slip; hence, defining a fault as oblique requires both dip and strike components to be measurable and significant. Some oblique faults occur within transtensional and transpressional regimes, and others occur where the direction of extension or shortening changes during the ...
The initially theory consisted of Haupl-Andersen's ideas who believed that Isometric Muscular Contraction caused by Myotatic reflex activity was the primary way functional adaptation of the appliance took place. The functional adaptation led to a new way of mandibular closing pattern.
Philip Warren Anderson ForMemRS HonFInstP (December 13, 1923 – March 29, 2020) was an American theoretical physicist and Nobel laureate.Anderson made contributions to the theories of localization, antiferromagnetism, symmetry breaking (including a paper in 1962 discussing symmetry breaking in particle physics, leading to the development of the Standard Model around 10 years later), and high ...
The principles of the chemo-parasitic theory were bolstered by the descriptions of bacterial plaque on tooth surfaces independently by GV Black and by JL Williams in 1898. The biomass of plaque helps localize acids at the tooth surface and prevent dilution by saliva. Miller thought that no single species of bacteria could cause caries.
The tooth-root translucency method was pioneered in the 1990s and involves taking two measurements of a tooth when viewing it under a light, and then placing the values into a formula to gain an age estimation. [3] Another common method involves counting the number of alternating light and dark bands in the cementum. [3]
