High Quality Content by WIKIPEDIA articles! In geometry, a straight skeleton is a method of representing a polygon by a topological skeleton. It is similar in some ways to the medial axis but differs in that the skeleton is composed of straight line segments, while the medial axis of a polygon may involve parabolic curves. The straight skeleton is defined by a continuous shrinking process in which the edges of the polygon are moved inwards parallel to themselves at a constant speed. As the edges move in this way, the vertices where pairs of edges meet also move, at speeds that depend on the angle of the vertex. If one of these moving vertices collides with a nonadjacent edge, the polygon is split in two by the collision, and the process continues in each part. The straight skeleton is the set of curves traced out by the moving vertices in this process.

The textbook written by the professors of the Biological Chemistry Department of the I.M. Sechenov First Moscow State Medical University (Sechenov University) approaches сomplicated modern scientific data about a molecular basis of the functioning of the organism in an intelligible form. This edition contains illustrative material, test tasks and situational problems in each of 14 sections. All the problems proposed for the individual solution have "guiding" questions that help students to solve them. Most of these tasks are based on the questions covered in the special course "Biochemistry of connective tissue. Biochemistry of mixed saliva". The textbook is intended for medical students who specialize in Dentistry, and can be...
