Moderne Analysenverfahren in der Gerichtlichen Chemie

The use of modern chemical and physical methods in forensic chemistry and crime investigation is steadily increasing and gaining in importance. For forensic purpose special modifications of the procedures are generally required in order to give results which are acceptable to legal authorities as proof of some specific points. The chemical toxicology can also help in cases of acute intoxications or in environmental problems.     

Moderne Wissenschaftstheorie. Ein Überblick

In the present article, first, the considerable superiority of modern logic to traditional (aristotelian) logic is described with reference to logical connectives, quantifiers and relations. Second, it is shown how the antinomies of set theory created the foundational crisis of mathematics, leading to three different approaches, namely intuitionism, pragmatic axiomatics and proof theory.     

Moderne Wissenschaftstheorie. Ein Überblick

This second part deals with the philosophy of the empirical sciences. It contains the following subjects: modern empiricism vs. old English empiricism, Popper's falsificationism, Carnap's inductive logic, some of the problems connected with statistical probability, the two-level conception of the language of science, and modern approaches to scientific explanation. In addition, I have included one section on the linguistic turn of the thirties (Wittgenstein, Carnap) and one on the historical turn of the sixties and seventies (T.S. Kuhn).     

Energie-Speicherung und Methoden des Energie-Transports

The Science of Nature - Because of the sudden rise in primary-energy costs and the rapid inflation of plants which are used for the conversion of primary to secondary energy, the storage of energy,...     

Moderne Elektronenmikroskopie auf zellulärem und makromolekularem Niveau

Conventional electron microscopy has significantly contributed to the understanding of structure-function relationships in living systems on cellular and macromolecular levels. New approaches and strategies will provide further insight into the organization of life. These new developments include cryopreparation and imaging techniques, X-ray microanalysis on frozen samples, electron energy loss spectroscopy, electron spectroscopic imaging, electron microscopic immunocytochemistry, preparation and imaging of ordered two-dimensional arrays of macromolecules, and computer image analysis and reconstruction. The techniques are described. Selected examples illustrate potential and limitations of these approaches and strategies.
