Polydispersive index: It is the ratio of weight average molecular mass and number average molecular mass of Polymers. For example, Nylon, which contains nitrogen atoms in the repeated unit backbone. In any power electronic switches, there are two types of losses; conduction loss and switching loss.The conduction loss means ON state loss in the switch and the switching loss means OFF state loss in switch. Picture Source: wikimedia.org. The polymer that is similar to the metal in terms of their electrical, electronic, magnetic, and optical properties is termed as ‘intrinsically conducting polymer (ICP)’ or ‘synthetic metal’. (4, 5, and 6). In the fat cells, there’s an abundance of lipids in the form of triglycerides; an ester that formed from glycerol and fatty acids. The primary classification of dyes is based on the fibers to which they can be applied and the chemical nature of each dye. It has an open grain and is reasonably hard wearing. A Hydrocarbon backbone being a long chain of linked carbon and hydrogen atoms, possible due to the tetravalent nature of carbon. The most important use of polyvinyl chloride is the manufacture of sewage pipes. Part 7 - Self Test Lab 5 Introduction Lab 5 . There are two major classifications: non-saponifiable and saponifiable. Lipids have two molecules – fatty acids and glycerol. Polymers are all created by the process of polymerization wherein their constituent elements called monomers, are reacted together to form polymer chains i.e 3-dimensional networks forming the polymer bonds. Def: Sutures are Junctions or lines of articulation between adjacent bones of skull. In the body, they are stored in adipose tissues. Sutures and suturing techniques Nonabsorbable sutures may be used as deep sutures to provide prolonged mechanical support. On the other hand, fatty acids have an acid group at one end of the molecule and a hydrocarbon chain. Media are of different types on consistency and chemical composition. Lipid signaling plays an important role in cellular signaling/cell communication. For lipids to be metabolized by the body it involves fatty acid oxidation to generate the energy needed to synthesize new lipids from minute molecules. Although characterized as non-absorbable, studies show that it loses most of their TS after 1 yr. and cannot be detected in tissues after 2 yrs. A. Synthetic rubbers are prepared by this polymerization. As chain length and cross-linking increases the tensile strength of the polymer increases. Addition of 5% of sulphur, enhances the crosslinking of the linear chains and thus improves the stiffening of the rubber for an application like vehicle tires. Generally, all types of machinery are provided with supports for rotating shafts, the supporting device is known as a bearing.In other words, a bearing is a machine element that constrains relative motions and used to reduce the friction between moving parts.. A few examples of a hydrocarbon backbone polymer are polypropylene, polybutylene, polystyrene. Lipids are among the major organic molecule groups. Compared to conventional molecules with different side molecules, the polymer is enabled with hydrogen bonding and ionic bonding resulting in better cross-linking strength.
