(5). a) What are sheet-molding compounds (SMC)? Bulk-molding compounds (BMC)? Sheet-molding compound (SMC) is a fiber glass reinforced thermosetting compound in sheet form‚ usually rolled into coils interleaved with plastic film to prevent auto adhesion. Made by dispensing mixed resin‚ fillers‚ maturation agent‚ catalyst and mold release agent onto two moving sheets of polyethylene film. The lower one also contains chopped glass roving or glass mat. SMC can be molded into complex shapes

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Composition and Formation of Myelin Sheath Molecular Neurobiology Myelin may be made by different cell types‚ varies in chemical composition and configuration‚ but performs the same insulating function. Myelin is about 40% water; the dry mass of myelin is about 70 - 85% lipids and about 15 - 30% proteins. Some of the proteins that make up myelin are myelin basic protein (MBP)‚ myelin oligodendrocyte glycoprotein (MOG)‚ and proteolipid protein (PLP). The primary lipid of myelin is a glycolipid

Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise

Composition of Concurrent Forces Abstract— The experiment aims to show the relationship of different forces acting at the same time by using different variables namely‚ the equilibrant force‚ the resultant‚ and the given forces Fa and Fb. The equilibrant force is the force that establishes equilibrium while the resultant is the addition of the given forces and is also the opposite of the equilibrant. The objective of the experiment is to determine the resultant of two forces experimentally‚ to
