The Pirogov triangle (also Piragoff's triangle) is an area in the human neck formed by the intermediate tendon of the digastric muscle, the posterior border of the mylohyoid muscle, and the hypoglossal nerve.
This free software had an earlier incarnation, Macsyma. Developed by Massachusetts Institute of Technology in the 1960s, it was maintained by William Schelter from 1982 to 2001. In 1998, Schelter obtained permission to release Maxima as open-source software under the GNU General Public license and the source code was released later that year ...
Interactive geometry software (IGS) or dynamic geometry environments (DGEs) are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. In most IGS, one starts construction by putting a few points and using them to define new objects such as lines , circles or other points.
Casio BASIC is a programming language used in the Casio calculators such as the ClassPad, PRIZM Series, fx-9860G Series, fx-5800P, Algebra FX and CFX graphing calculators.It is also known as "BasicLike" in some models.
One triangle is defined for each vertex presented after the first two vertices. For odd n, vertices n, n + 1, and n + 2 define triangle n. For even n, vertices n + 1, n, and n + 2 define triangle n. n – 2 triangles are drawn. Note that n starts at 1. The above code sample and diagram demonstrate triangles drawn in a clockwise orientation.
The primary face of the subdivision is called a principal polyhedral triangle (PPT) or the breakdown structure. Calculating a single PPT allows the entire figure to be created. The frequency of a geodesic polyhedron is defined by the sum of ν = b + c. A harmonic is a subfrequency and can be any whole divisor of ν.
‡ Support for periodic systems (3d-crystals, 2d-slabs, 1d-rods and isolated molecules): 3d-periodic codes always allow simulating systems with lower dimensionality within a supercell. Specified here is the ability for simulating within lower periodicity.
Nikolay Pirogov was born in Moscow, the 13th of 14 children of Ivan Ivanovich Pirogov (born around 1772), a major in the commissary service and a treasurer at the Moscow Food Depot whose own father came from peasants and served as a soldier in Peter the Great's army before retiring and opening a brewery in Moscow; Pirogov's mother Elizaveta Ivanovna Pirogova (née Novikova) belonged to an old ...
