In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles, composite particles, and atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution: it arises when a particle executes a rotating or twisting trajectory. The existence of spin angu

Lake Carriersâ Association (âLCAâ) represents U.S.-flag vessel operators on the Great Lakes. The Association's 16 member companies operate 56 U.S.-flag self-propelled vessels and tug/barge units (âlakersâ) ranging in length from 494 to 1,013.5 feet.These vessels can carry more than 115 million tons of cargo in a year.ron ore, limestone and coal are the primary commodities carried by LCA members. Other cargos include cement, salt, sand and grain. The vast majority of cargos carried by U.S.-flag lakers move between U.S. ports, in what is commonly referred to as the Jones Act trades.
