Electrical Contacts

Electrical Contacts

Autor: Paul G. Slade

Número de Páginas: 1314

Covering the theory, application, and testing of contact materials, Electrical Contacts: Principles and Applications, Second Edition introduces a thorough discussion on making electric contact and contact interface conduction; presents a general outline of, and measurement techniques for, important corrosion mechanisms; considers the results of contact wear when plug-in connections are made and broken; investigates the effect of thin noble metal plating on electronic connections; and relates crucial considerations for making high- and low-power contact joints. It examines contact use in switching devices, including the interruption of AC and DC circuits with currents in the range 10mA to 100kA and circuits up to 1000V, and describes arc formation between open contacts and between opening contacts. Arcing effects on contacts such as erosion, welding, and contamination are also addressed. Containing nearly 3,000 references, tables, equations, figures, drawings, and photographs, the book provides practical examples encompassing everything from electronic circuits to high power circuits, or microamperes to mega amperes. The new edition: Reflects the latest advances in electrical...

Sand and Sandstone

Sand and Sandstone

Autor: F. J. Pettijohn , Paul E. Potter , Raymond Siever

Número de Páginas: 586

The first edition appeared fourteen years ago. Since then there have been significant advances in our science that warrant an updating and revision of Sand and Sandstone. The main framework of the first edition has been retained so that the reader can begin with the mineralogy and textural properties of sands and sandstones, progress through their organization and classification and their study as a body of rock, to consideration of their origin-prove nance, transportation, deposition, and lithification-and finally to their place in the stratigraphic column and the basin. The last decade has seen the rise of facies analysis based on a closer look at the stratigraphic record and the recognition of characteristic bed ding sequences that are the signatures of some geologic process-such as a prograding shallow-water delta or the migration of a point bar on an alluvial floodplain. The environment of sand deposition is more closely determined by its place in such depositional systems than by criteria based on textural characteristics-the "fingerprint" approach. Our revi sion reflects this change in thinking. As in the geological sciences as a whole, the concept of plate tectonics has...

A Selected Bibliography on the Sociology of Language with the Emphasis on Sources on Language Planning in Africa

A Selected Bibliography on the Sociology of Language with the Emphasis on Sources on Language Planning in Africa

Autor: August Dawid De Villiers Cluver

Número de Páginas: 670

This work aims to provide the most comprehensive bibliography in the domain of Sociolinguistics and in the field of language planning. The 640-page publication gives access to a large percentage of the published literature via a sophisticated thesaurus. As the title indicates, Africa, and specifically southern Africa, is covered in great detail. Sources on the history and development of the languages of Namibia and Zimbabwe have been included. Apart from sources on the languages of Africa, the bibliography also offers a comprehensive overview on topics such as language conflict, language decline, language development, and language rights, as well as a section on translations and interpreting. The categorisation of sources is intended to stimulate researchers and postgraduate students, and this makes the bibliography an indispensable tool for librarians and senior academics.
