PPT-Fibers

2 Fibers Are considered class evidence Have probative value Are common trace evidence at a crime scene Can be characterized based on comparison of both physical and chemical properties Identification . Volume 5, Issue 3 - 2010 How Is Frayed Fiber Generated during Refining Process? Yuhe Chen and Mousa M. Nazhad, Ph.D. ABSTRACT The objective of this study is to characterize frayed NERVE TERMINATIONS. The nerve fiber traveling in peripheral nerves terminate in peripheral structures to which or from which they convey nerve impulses.. Accordingly the nerve terminations are classified into two major groups:. The dense layer of the basal lamina of all epithelial tissue is created by connective tissue. . Connective tissue connects the epithelium to the rest of the body.. Three Basic Components. Specialized cells. Natural dyes. Text: Chapter 12 . pp. 400-405. Natural . fibers: cellulose. . (polysaccharides). Text: Chapter 4 . pp. 143-149. Cellulose Fibers. . Cotton. Linen. Cellulose Derivatives. (viscose) Rayon. Chapter. Objectives. List. the main characteristics of natural and manufactured fabrics.. Explain. how fibers are manufactured..
