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.
Woven polypropylene, non-woven polypropylene and RPET are the most common recycled fabrics we use. Polypropylene, also known as PP, is a thermoplastic resin material made from post-industrial, or rather pre-consumer, recycled content. RPET is a fabric made from recycled plastic bottles.
