The history of growth theory is conventionally divided into two phases: until early 1970’s, the research is labeled exogenous growth theory, and, starting in late 1980’s until the present, the new growth or endogenous growth

General introduction,osteffective surfactant, although essential, is not easy due to: the bewildering number of surfactants available on the market; insufficient data given by the manufacturers; poorly defined chemical structure/effect relationships. This book attempts to provide some practical help with these problems

Information sources,urface active agents are chemicals they are not pure, and the products of commerce are mixtures of chemicals of very similar but not identical properties. Thus publications such as Beilstein and the Registry file of Chemical Abstracts are of very limited use. The major source of information on surfa

Use of surfactant theory,erved results. The application of theory will not lead to quick, easy solutions of practical problems. However there is a need to have a grasp of theory for a better understanding of the mode of action of a surfactant. This helps in the more rapid and efficient selection of the correct surfactant, a
