81Orbifold — This terminology should not be blamed on me. It was obtained by a democratic process in my course of 1976 77. An orbifold is something with many folds; unfortunately, the word “manifold” already has a different definition. I tried “foldamani”,… …

83Social construction of technology — (also referred to as SCOT) is a theory within the field of Science and Technology Studies (or Technology and society). Advocates of SCOT that is, social constructivists argue that technology does not determine human action, but that rather, human …
84Topological string theory — In theoretical physics, topological string theory is a simplified version of string theory. The operators in topological string theory represent the algebra of operators in the full string theory that preserve a certain amount of supersymmetry.… …
85TM-Sidhi program — The TM Sidhi program is a form of meditation introduced by Maharishi Mahesh Yogi in 1975. It is based on, and described as a natural extension of the Transcendental Meditation technique (TM).[1][2] The purpose of the TM Sidhi program is to… …
86Dance and health — has been subject of a number of research studies which show dance to be a very healthy exercise. However there are a number of health risks of professional dance which require careful attention. As part of courtship dance is a reliable indicator… …
87Variable fractional delay filter — Introduction= One important advantage of the variable digital filter is that the frequency characteristics, including the magnitude response and the phase response are tunable without re implementation of the filter. Variable fractional delay… …

89Metal nitrosyl complex — Metal nitrosyl complexes are complexes that contain nitric oxide, NO, bonded to a transition metal.[1] Many kinds of nitrosyl complexes are known, which vary both in structure and coligand. Contents 1 Bonding and structure 1.1 Linear vs bent… …
90Non-critical string theory: Lorentz invariance — Usually non critical string theory is considered in frames of the approach proposed by Polyakov [1]. The other approach has been developed in [2] [3] [4]. It represents a universal method to maintain explicit Lorentz invariance in any quantum… …
