I hit what exactly is alchemy Even the origin and definition ()l the word are obscure. In China it represents the quest for immortality, in India it is the art of making medicines, while in (he West it is associated with the quest for the Philosopher s Stone, which transmutes base metals into gold. Alchemy is aU these things, and more besides.

The fourth chapter begins with the origin and definition of MFI. It then develops the fundamentals of the unification technique based on a strong theoretical rationale. A demonstration of the use of this technique is followed by ample master rheograms of shear viscosity for a long list of common homopolymers, copolymers, blends, PVC formulations, and filled and recycled polymers. 

Aristotle defined life as animation, life can be also defined as mechanism or organization (Kant). Until very recently, viruses were not considered in discussions on the origin and definition of life. This situation is rapidly changing, and it has been recognized that viruses have played (and still play) a major innovative role in the evolution of cellular organisms (Forterre, 2010 [134]). Life scientists and chemists have not come to a conclusive definition of life. There are several characteristics for life as we know it from Earth ...

The study clearly shows that the observed electrical signals are electrochemical in origin, and the first-order description of the process is consistent with that expected from atmospheric pressure behaviors. Nevertheless, the complications introduced by the shock compression do not permit definitive conclusions on values of electrochemical potentials without considerable additional work. 

Whether this is true or not, meteorites give us one definite piece of information. Isotopic analysis shows that each element in a meteorite has the same isotopes in the same percentages that this same element has on earth. The accepted explanation for this fact is that meteorites and the earth share a common origin and that they became separated after the elements were created. 

On the basis of these assumptions, the position of a band on the chromatogram is defined by measuring the distance between the origin and the geometrical center of the band. Despite the considerable imprecision of this definition for skewed (i.e., non-Gaussian) bands, its two feamres are of great importance ... 

For origins of fullerene chirality and definitions of configurational description factors fC and fA (f = fullerene, C = clockwise, A = anticlockwise), see C. Thilgen, A. Herrmann, F. Diederich, The Covalent Chemistry of Higher Fullerenes C70 and Beyond , Angew. Chem Int. Ed. Engl. 1997,36,2269-2280. 

In this chapter brief information on the origin and cost of titanium will be discussed. A definition of the term unique properties will be given and how these properties are exploited in the membrane, diaphragm and in the mercury cell processes will be considered and miscellaneous applications touched upon. The chapter will conclude with a summary of the financial benefits which, after all, propel the use of this challenging material. 

Dr. Mark is acknowledged throughout the scientific community as the father of polymer science. He received the National Medal of Science in 1980, the 1978 Senior U.S. Scientist Award, 29 other medals and awards from various international organizations, and 17 honorary degrees. In 1977, he was appointed as an Honorable Member of the Japan Chemical Society. He has published over 500 original and review articles and some 20 books on topics related to polymer chemistry. Dr. Mark is founder and first editor of the Journal of Polymer Science, the definitive publication in its field, and is currently editor of the Journal of Applied Science and associate editor of the Textile Research Journal. In addition to these duties he serves as Chairman of the Editorial Board of the Encyclopedia of Polymer Science and Technology. 

Consideration will be given first to some of the more chemically complex flavoring materials, which are of natural origin. The definitions which follow are, of necessity, general in nature and not necessarily all inclusive. 

While the Dove formulation has undergone relatively minor changes since its launch in the U.S. in 1955, the marketing concept has seen major changes. Today s Dove is marketed on a platform of extreme mildness to skin as evidenced by its neutral pH, and has been extended into different skin cleansing product forms (e.g. Dove Body Wash) as well as other personal care products (e g. Dove Shampoo, Dove Deodorant) [3], However, the original problem definition had a very different focus. 

The chemical composition of petroleum also varies over a wide range. A broad functional definition of petroleum hydrocarbons is that hydrocarbons are composed primarily of many organic compounds of natural origin and low water solubility. 

American readers should note, en passant, that the original (European) definition of a trillion is a million million millions, that the definition of a billion is a million millions, and that what they refer to as a billion is correctly referred to as a milliard (how the desire to be a billionaire can distort language ).
