They describe ethylene methyl acrylate copolymer toughened polymethyl methacrylate blends and synthesis and characterization for thermal, mechanical, optical, and morphological properties; molecular dynamics simulation studies for binary blend miscibility; conformation and topology of cyclic linear polymer blends; strain hardening in blends with fibril morphology; modification using irradiation techniques; and directed assembly using nanopatterned chemical surfaces.
According to most accounts, the rings were adopted by Baron Pierre de Coubertin (founder of the modern Olympic Movement) in 1913 after he saw a similar design on an artifact from ancient Greece. The five rings represent the five major regions of the world: Africa, the Americas, Asia, Europe, and Oceania.Every national flag in the world includes at least one of the five colors, which are (from left to right) blue, yellow, black, green, and red.It is important to emphasize that Pierre de Coubertin never said nor wrote that the colors of the rings were linked with the different continents.very national flag in the world includes at least one of the five colors, which are (from left to right) blue, yellow, black, green, and red.
