摘要:

AbstractAgainst the background of increasing demand and limited availability of fossil, non‐regenerative fuel reserves and resources, ways are indicated of ensuring future supplies of raw materials and energy. The ambivalence of petroleum, natural gas, and coal in the energy and chemical sectors is demonstrated and opportunities for the gradual separation of their dual function are indicated. Taking into account the time factor, the necessary restructuring processes are analyzed critically with respect to their impact on the raw material–polymer relations

摘要:

AbstractHuman blood plasma contains a large number of proteins. New analytical and preparative techniques have so far permitted the isolation of more than one hundred such proteins; about ninety percent of these were first characterized in the last 30 years. The plasma proteins include components of the clotting and complement systems as well as proteinase inhibitors, immunoglobulins, lipoproteins, and carrier proteins. The biological function of some of the plasma proteins is not yet known. Deficiency of one or more plasma proteins usually causes serious health disorders, the best known example being hemophilia. Several biologically active proteins can be gained from blood plasma; these proteins—for example the blood clotting factors—are of great prophylactic and therapeutic importance and allow a better exploitation of the valuable plasma than can be obtained by means of transfus

摘要:

AbstractThe economic reproduction of graphic information was first made possible in the western world byGutenberg'sinvention of movable type. In the printing methods of that time, mechanical transfer processes played the major role, while chemical processes were of secondary importance. WhenAlois Senefelderinvented planographic printing (lithoprinting) at the end of the 18th century he called the new process “chemical printing”. Since then, chemistry has attained great importance in the production of printing forms: Thus the manufacture of surface (litho‐) printing forms with light required temporary storage materials and image reproduction processes based on chemical reactions. Since the advent of electronic processing of information, however, several former temporary storage media have become obsolete; newer, more sensitive image reproduction processes are increasingly making less use of chemical principles than of the electrical properties of mate
