Energy efficient motors are motors in which better quality parts, increased conductor size, higher quality steel, and improved design are combined to produce motors with full load efficiencies higher than standard motors. Energy efficient motors maintain high efficiency at low loads. They usually have inherently higher power factors than standard motors and maintain higher power factors under partial load operations. Energy efficient motor windings will generally have longer life than standard motor windings, because they run cooler. This motor reference guide is the result of data and information collected and organized by the Industrial and Large Commercial staff of the Tennessee Valley Authority. Additionally, computer simulations were performed to develop data not currently available in literature. The guide is not intended to be a textbook on motors, but a quick and ready reference to assist in the technical and economic evaluation of energy-efficient motors versus standard motors. However, chapters on motor related topics such as rotating fields, power factor correction and impact of power quality on motor performances have also been included to complement the text.
"Rivers of Oregon captures the beauty and the intrinsic qualities of the state's irresistible riverscapes like no other book has done. From the underwater view and from the refuge of riparian forests, from the seat of a canoe or raft and from distant mountain summits, readers will gain new perspectives on the extraordinary features that provide us with water, with life, and with scenes whose loss would leave us deeply impoverished."--

The book brings to light how great and true knowledge is born of intuition, quite different from modern Western method. The ancient Indian method and its secret techniques are examined and shown to be capable of solving various problems of mathematics. The universe we live in has a basic mathematical structure obeying the rules of mathematical measures and relations. All the subjects in mathematics-Multiplication, Division, Factorization, Equations, Calculus, Analytical Conics, etc.-are dealt with in forty chapters, vividly working out all problems, in the easiest ever method discovered so far.
Brilliantly researched and wonderfully written, LOVE AND CAPITAL reveals the rarely glimpsed and heartbreakingly human side of the man whose works would redefine the world after his death. Drawing upon previously unpublished material, acclaimed biographer Mary Gabriel tells the story of Karl and Jenny Marx's marriage. Through it, we see Karl as never before: a devoted father and husband, a prankster who loved a party, a dreadful procrastinator, freeloader, and man of wild enthusiasms-one of which would almost destroy his marriage. Through years of desperate struggle, Jenny's love for Karl would be tested again and again as she waited for him to finish his masterpiece, Capital. An epic narrative that stretches over decades to recount Karl and Jenny's story against the backdrop of Europe's Nineteenth Century, LOVE AND CAPITAL is a surprising and magisterial account of romance and revolution-and of one of the great love stories of all time.
