Ideal for removing large amounts of liquids from wells, Electrical Submersible Pumps (ESP) are perhaps the most versatile and profitable pieces of equipment in a petroleum company's arsenal. However, if not properly maintained and operated, they could quickly become an expensive nightmare. The first book devoted to the design, operation, maintenance, and care, Electrical Submersible Pumps Manual delivers the tools and applicable knowledge needed to optimize ESP performance while maximizing of run life and the optimization of production. The prefect companion for new engineers who need

This is the third and final volume of the Etymological Dictionary of Egyptian . It comprises the Egyptian words with initial m-. The amount of material offered, the extensive treatment of scholarly discussions on each item, and the insights into the connections of Egyptian and the related Afro-Asiatic (Semito-Hamitic) languages, including many new lexical parallels, will make it an indispensable tool for comparative purposes and an unchallenged starting point for every linguist in the field. The reader will find the etymological entries even more detailed than those of the introductory volume, due to the full retrospective presentation of all etymologies proposed since A. Erman's time, and thanks to an extremely detailed discussion of all possible relevant data even on the less known Afro-Asiatic cognates to the Egyptian roots.

This volume is paying homage to the memory of Werner Vycichl (1909-1999), one of the most outstanding figures of Semito-Hamitic (Afro-Asiatic) comparative linguistics. The contributions by well-known specialists comprise almost all principle branches of the Semito-Hamitic macrofamily. The volume is divided in five major sections following the areas of interest of W. Vycichl: Egyptology and Coptology, Semitic linguistics, Beja (Northern Cushitic), Chadic, and general Semito-Hamitic (Afro-Asiatic) comparative linguistics (Berber has been excluded, since we already have a separate Mémorial Werner Vycichl with articles only in Berberology). The volume is important for the researchers in all the linguistic fields enumerated above as well as for those interested in African or comparative linguistics in general.

The handbook The Semitic Languages offers a comprehensive reference tool for Semitic Linguistics in its broad sense. It is not restricted to comparative Grammar, although it covers also comparative aspects, including classification. By comprising a chapter on typology and sections with sociolinguistic focus and language contact, the conception of the book aims at a rather complete, unbiased description of the state of the art in Semitics. Articles on individual languages and dialects give basic facts as location, numbers of speakers, scripts, numbers of extant texts and their nature, attestati
