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.
synthetic absorbable suture an absorbable suture produced from strands of polymers; the most commonly used materials are polyglactin 910 (Vicryl) and polyglycolic acid (Dexon); the latter is more rapidly absorbed.. material used in closing a wound with stitches. adj., adj suÂ´tural. Various types of sutures. From Dorland's, 2000. absorbable suture a strand of material that is used for closing wounds and becomes dissolved in the body fluids and disappears; types include surgical gut, tendon, and some synthetics.
