Focusing on English and German examples, the study deals with the temporal interpretation of texts in non-aspect languages. The author presumes that a coherent interpretation of a text results from a complex interaction between linguistic and extra-linguistic information. The study presents a unified account of the semantics of temporality which treats the varying grammatical factors (aspectual classes, tense, and discourse structure) in a systematic way.

Glass Chemistry is concerned with the relation of chemical composition, structure and properties of various glasses. The book has been translated from the third German edition, which serves as a textbook for university students in materials sciences and a reference book for scientists and engineers in glass science and production. The central themes of the book are the chemistry and physics of glass. Detailed knowledge of the compositional and structural facts is the basis for the systematic development of new glasses as construction and optical materials. Glass Chemistry is an interdisciplinary book on the borderlines between chemistry, physics, mineralogy and even biology and medicine. The book represents a well balanced treatment for students, scientists and engineers.
