After reading the article and taking the test, the participant will be able to: 1. Describe the anatomy and physiology of the skin. 2. Describe the wound healing process, the local and systemic factors that may impair healing, and the parameters that assess the wound status. 3. Describe the steps in the process to prepare the wound bed for healing.

A series of branched poly(ethylene terephthalate) samples was prepared by employing 0.07-0.42 mol % trimethylolpropane (TMP) for melt polycondensation. These polymers were characterized with respect to molar mass, intrinsic viscosity, and melt viscosity. Spinning into fibers took place at spinning speeds ranging from 2500 to 4500 m/min. The molecular orientation of the fibers as measured by birefringence and polarized fluorescence decreases with growing amounts of TMP, as does crystallinity. Thus with slightly branched polymers, higher spinning speeds than with a linear polymer can be used to achieve a certain property profile.
