pt. 1. Morphosyntax -- pt. 2. Semantics -- pt. 3. Phonology -- pt. 4. Language contact.

Sommario/riassunto

The 16 papers in this volume are revised versions of papers presented at the conference; they represent the state of the art in various subfields of African linguistics into which the book is organized: (1) morphosyntax, (2) semantics, (3) phonology, and (4) language contact. The last part covers topics such as code-switching and mixing, pidginization/creolization, and language planning. The papers in Part I: Morphosyntax focus particularly on the verb and verb phrase in a variety of Niger-Congo languages, discussing several aspects of the verb morphology.

Sommario/riassunto

The Foseco Ferrous Foundryman's Handbook is a practical reference book for all those concerned with making castings in any of the commonly used alloys, by any of the usual moulding methods.International SI units are used throughout, but in almost all cases conversions to the more familiar Metric and Imperial units are given. Wherever possible, Casting Alloy Specifications include equivalent specifications for several countries as well as international specifications.  Individual chapters cover the casting of light alloys, copper-based alloys, all types of cast-iron and steel.
