The present Supplement Volume Beryllium A 3 continues and completes the description of the physical properties of the element, begun in Supplement Volume A 2, 1991, and also treats the electrochemical behavior of the metal. The unique combination of the Be properties, which was pointed out in Supplement Volume A 2, is also demonstrated in the following chapters of this Volume A 3: 13. Electrical Properties 14. Electronic Properties 15. Optical Properties. Emission and Impact Phenomena 16. Electrochemical Behavior Starting with the electrical properties, Be isarather good electrical conductor in centrast to what might be expected. Superconductivity was studied, especially on films. Quantum effects, which are more pronounced in Be than in most other metals, are the reason for numerous in vestigations of the magnetoresistance and the magnetic-breakdown effect. The basis for many of the characteristic properties is the unique nature of bonding in Be as a consequence of its peculiar electronic structure and the special shape of its Fermi surface which also gave rise to further numerous studies. Detailed cluster calculations were per formed to better understand the bonding in the metal. Regarding the optical properties, the high reflectivity of Be, particularly in the infrared region, makes it attractive for the fabrication of precision optical surfaces (mirrors); it is also useful for solar-collector surfaces in spacecraft applications. Emission and electron-and ion impact phenomena as well as neutron optics are also discussed.
How was the nature of women redefined and debated during the French Enlightenment? Instead of treating the Enlightenment in the usual manner, as a challenge to orthodox ideas and social conventions, Lieselotte Steinbrugge interprets it as a deviation from a position staked out in the seventeenth century, namely, "the mind has no sex.".
Despite the advances of radio and television and increasing mobility and urbanization, spoken English is by no means becoming more like the written standard. English dialect grammar, however, is still a new and relatively undeveloped area of research, and most studies to date are either restricted regionally, or based on impressionistic statements. This book provides the first thorough empirical study of the field of non-standard negation across Great Britain.
On the basis of synchronic and diachronic data analysis, the volume takes a close look at the synchronic layers of binominal size noun and type noun uses (a bunch/a load of X; a sort of X; a Y type of X) and reconsiders the framework of grammaticalization in view of issues raised by the phrases under discussion. As a result, a construction grammar-approach to grammaticalization is developed which does justice to the syntagmatic lexical, or collocational, reclustering observed in the data within an eclectic cognitive-functional approach.
Beryllium Supplement Volume A2 describes the properties of the bulk metal, the main emphasis being on the crystallographic structure and the structure-related (mechanical) properties. The great importance of this metal, for instance in nuclear and space technologies, results from its unique combination of properties, i.e., low density, extremely high elasticity modulus, and relatively high melting point. In addition, Be played a particular role in studying the fundamental mechanisms of deformation in the lattices of metals. On this basis, numerous factors contributing to the ductility or brittleness of Be are discussed. Thermal and magnetic properties complete the description of Be in this volume.
