Cellulitis is a bacterial infection of the skin. Bacteria get into the skin through a cut, scrape, or other wound. Cellulitis can also affect the deeper layers of connective tissue beneath your skin and, in severe cases, spread to your lymph nodes.
Comparing the Major Synthetic Rope Materials. When deciding what rope best suits your need, it is often a matter of compromise. There are 5 major synthetic ropes in use for boat and marine applications. Polypropylene, Polyester, Nylon, UHMWPE (Ultra High Molecular Weight Polyethylene) and Aramids (KevlarÂ®, TechnoraÂ®, VectranÂ®, etc). Each has outstanding virtues and each has faults.
Let's start by defining two important terms:  tensile strength  and  working load . Tensile strength is the average strength of new rope under laboratory conditions. This is determined by wrapping the rope around two large diameter capstans and slowly tensioning the line until it breaks.
