By the end of the thirteenth century the regions of Europe, the Middle East, the Indian Ocean area, and China were becoming integrated--through activities in an archipelago of cities located along major land and sea routes--into a world system of commerce and production, albeit one in whichEurope still played a minor role. This book traces the formation of the system and explores how the Black Death, circa 1350, and the subsequent isolation of China under the Ming dynasty interrupted its further development. Abu-Lughod argues that demographic, geographic, and political factors, ratherthan any unique qualities of Western capitalism or "personality," account for the eventual triumph of "the West" during the ensuing period of six hundred years, and suggests that current transformations in the world system may signal the end of this aberrant phase of world history. |

Sommario/riassunto |
|
Basic factors and general considerations in selecting the class and means of neutral grounding for a particular ac transmission or subtransmission system are covered. An apparatus to be used to achieve the desired grounding is suggested, and methods for specifying the grounding devices are given. Transformer tertiary systems, equipment-neutral grounding, and the effects of series compensation on grounding are discussed. |
