It is clear that the discovery of solar eigenmodes and the resulting possibility of probing the solar interior is an event of primary importance for solar physics in general and for theories of the inner solar angular velocity in particular. While these theories are basic for the understanding of the solar spin down, differential rotation, dynamo and activity, they are however, extremely complex, and in all likelihood only limited further progress could have been achieved without the guidance of observations. Until recently and in spite of the scant observational basis the theoretical work has moved forward as the perusal of this book shows. There cannot be any doubt, however, that the present, rapidly expanding, worldwide observational program will lead ultimately to a vigorous theoretical development of the field. It appeared to the organizers that a meeting centered on theories of the inner solar angular velocity, comprising presentations of the main research areas by the involved scientists, would significantly foster this development since it would help to clarify the basic ideas of the subject. The meeting, held at the National Solar Observatory/Sacramento Peak, from August 11 to August 14, was the eighth in a series of summer symposia at Sacramento Peak. The unqualified success of the meeting could not have been possible without the unlim ited devotion of the staff at Sacramento Peak, Ray Smartt, Frank and Pat Hegwer, Ramona Elrod in particular."

As an instructor in various finishing courses, I have frequently made the statement over the years that "In the field of metal finishing there is very little black and white, just a great deal of grey. It is the purpose of the instructor to familiarize the student with the beacons that will guide him through this fog. " To a very considerable extent, a handbook such as this serves a similar purpose. It is also subject to similar limitations. Providing all the required information would result in a multi-volume encyclopedia rather than a usable handbook. In the pages that follow, you will therefore find frequent references to other sources where more detailed explanations or information can be found. The present goal is proper guidance and the provision ofthe most frequently required facts, not everything that is available. In the 13 years since the last edition, changes in the finishing industry have been profound but in one sense have resulted in simplifying matters rather than complicating them. Because technology has advanced to a level of complexity rendering "home brew" impracti cal in many cases, dependence on proprietary compounds has become common. Therefore, detailed solution compositions are often no longer significant or even practical. It is thus more important to provide instruction about the factors that affect the choice of the most suitable type of proprietary material.

(Opening Address of 13th ESLAB Symposium) With GEOS and ISEE occupying a major part of the ESA scientific programme it was clear several years ago that a 'natural' basis for the 1978 ESLAB Annual Symposium would be the early data from these two spacecraft. During the 1976 meeting of the European Geophysical Society in Amsterdam it became apparent to me that a much wider community was interested and that in particular Working Group 2 of COSPAR was considering a GEOS session during its 1978 meeting here in Innsbruck. This was of course as it ought to be because GEOS had been adopted as the reference spacecraft for the International Magnetospheric Study. After some discussions with COSPAR and with the organizers of the STP Symposium which was held here last week we felt that in the interest of customer relations and following good common sense we should give up some of our independence in 1978 and merge our Symposium with COSPAR. I would gratefully acknowledge the co-operation of COSPAR's Working Group 2 chairman and vice-chairman, the active support of the President of COSPAR and the 'gentleman's agreement' with the STP programme committee which arranged that the new ISEE and GEOS results were routed to this Symposium rather than to the STP. I have talked about how we came to have this joint Symposium. Perhaps I should tell you too how we came close to having no Symposium.

Although classical electromagnetic (EM) field theory is typically embedded in vector calculus and differential equations, many of the basic concepts and characteristics can be understood with precursory mathematical knowledge. Completely revised and updated, Basic Introduction to Bioelectromagnetics, Second Edition facilitates the process of interdisciplinary research by introducing life scientists to the basic concepts of EM fields. This new edition outlines elements of EM that are helpful to life scientists working with physicists and electrical engineers. Each concept is presented with an associated application and discussion. Example applications include hyperthermia, neural stimulation, MRI, NMR, ultrasound, and cardiac pacing/defibrillation. With the liberal use of diagrams and graphs, this qualitative and illustrative point of access: Covers the entire frequency spectrum from direct current (DC) up through optical frequencies Includes more than 200 illustrations with 40 medical applications Incorporates examples from real applications to explain concepts Concentrates on the qualitative explanation of the key concepts, fundamental principles, and characteristic behaviors of EM fields, without mathematical rigor Offers practical rules of thumb to understand real situations Requires only an algebra background, in contrast to typical EM books that require vector calculus and partial differential equations Offering a simplified view of a very complex subject, this second edition provides an accessible introduction for life scientists and medical technologists on how EM fields work, what controls them, and the factors important to experimental setups.

Based on "Birds of Lore," this lighter, child-friendly bestiary and coloring book introduces young readers to the wondrous, unsung bird monsters from throughout history. Each page holds art ready to be colored or drawn on-some with suggested art challenges to practice. Each monster has a simple poem or story to explain something of its origin. Enjoy the fantastic birds of lore within

Follow the exploits of "The Mythologist" as he uses stolen technology to travel time and breach other dimensions in search of creatures that should never have existed. Each entry touches on the origins of a fantasy bird, or the most interesting parts of its history, while the wayward Mythologist deals with them in his reality. Based on a mysterious "found journal" and fully illustrated by talented artists, Birds of Lore is the closest you can get to mythological bird watching (without losing a finger). This modern bird bestiary could be described as a picture book for older readers, a cautionary sci-fi / fairy tale or one of the most unique coffee table art books you'll ever pick up. There is, quite frankly...nothing like it.
