Ancient Egyptians had a strong belief in preserving the body for the afterlife in hopes of achieving immortality. Part of this preservation was to protect and identify the body by painting or carving pictures‚ hieroglyphics‚ and symbols on the coffin. One very good example of this is represented by the ‘Mummy of Irethorrou in Coffin.’ This coffin‚ made of wood with polychrome‚ is adorned with hieroglyphics‚ symbols‚ and a portrait of the Egyptian priest.

the acid ionization constant‚ Ka. The equation for Ka incorporates the concentration of water as a constant value. Ka = [ H3O+][A-] [HA] and Ka = Kd [H2O] Organic acid ionization constants can cumbersome to work with because they are often very small numbers. Acetic acid‚ for example‚ has a Ka is value of about 0.00001 (or 10-5)‚ phenol has a Ka of 10-10. It is usually more convenient to use a logarithmic scale to handle these numbers. Accordingly‚ Ka values are transformed to pKa values

Emission Control Techniques 1. INTRODUCTION The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons‚ carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants
