Secondary Waves Defined. Secondary waves, or S-waves, are seismic waves produced by an earthquake. As one side of a fault slips past the other, the pressure that had been stored is released and travels radially away from the focus of the earthquake.
Non-Absorbable sutures include :- Polypropylene sutures, Nylon (poylamide), Polyester, PVDF, silk and stainless steel sutures. Monofilament and Multifilament Sutures. Sutures can also be divided into two types on the basis of material structure i.e. monofilament sutures and multifilament or braided sutures. Braided sutures provide better knot security whereas monofilament sutures provide better passage through tissues.
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes ...
