The traditional names of the rowan are those applied to the species Sorbus aucuparia, Sorbus torminalis (wild service-tree), and Sorbus domestica (true service-tree). The Latin name sorbus was borrowed into Old English as syrfe. The name service-tree for Sorbus domestica is derived from that name by folk etymology.
Restriction fragment length polymorphism. In molecular biology, restriction fragment length polymorphism, or RFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules from differing locations of restriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated.
  RTRP stands for Reinforced Thermosetting Resin Pipe and FRP stands for Fiberglass Reinfoced Plastic Pipe. FRP is a composite material consisting of a thermosetting polym â¦ er, often a type of polyester, reinforced with glass or other fibers.Glass fibers provide strength and stiffness to a composite material.  In fact,the RTR pipe have a m â¦ ore approperiate name as GRE(Glass  Reinforced Epoxy) Pipe, since that uses Epoxy Resin instead of  Polyester.    GRE Pipe have much superior properties than common RTR Pipe,  especially in properties of high pressure resistant.
