Introduction to the Magnetic Treatment of Fuel By R.J. Kita Hydrogen is the lightest and most basic element known to man. With its simple structure comprised of only one proton and one electron‚ it is one of the major constituents of all hydrocarbon based fuels. By studying the response of hydrogen with respect to magnetic fields and the accompanying increased energy output‚ much can be learned and applied to other related fuels. In the oxidation/combustion of hydrocarbon fuels‚ it is the outer shell of the

1.3 Transitional fossils A transitional fossil is any fossilised remains of a life form that has traits common to both a presumed ancestral group and its presumed derived descendant group. Transitional fossils are used as evidence to support evolutionary theory as they are suggested to demonstrate the gradual transition from one species to another through a multitude of changes. In essence‚ the transitional fossils are the remains of the species that have gone extinct‚ and these species are represented
