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.
The combination of polypropyleneâs properties makes it desirable for a broad mix of applications. In many areas where fluoropolymer tubing is typically used, polypropylene tubing can be employed as a relatively low-cost alternative. The high-crystalline composition also makes it good for use in structural systems.Polypropylene (PP) tubing is weldable and, when welded, can be used in non-fluid transfer applications.he combination of polypropyleneâs properties makes it desirable for a broad mix of applications.
