The aim of the authors in this monograph has been to present a general review of the magnetic properties of the rare earth metals, and a comprehensive, unified, and coherent account of the magnetic structures and excitations. These both reflect the nature of the fundamental interactions, and determine many of the characteristic properties of the metals. The authors have tried to concentrate on the essential principles and their applications to typical examples, generally restricting the discussion to the pure elements and considering alloys and compounds only when they are necessary to illuminate particular topics. Both authors have been involved for some time in the effort that has been made in Denmark to study, both theoretically and experimentally, the magnetic structures and especially the excitations in the rare earths. This account of the subject represents the results of their experience, and it is has been written in the hope that it will be useful not only to those who have a special interest in rare earth magnetism, but also to a wider audience who wish to learn something about the techniques and achievements of modern research in magnetism.

Im Zentrum dieses essentials stehen die zahlreichen Schnittstellen zwischen der IVV 3.0 und dem kollektiven Arbeitsrecht. Hier geht es um Fragen wie etwa, was in Instituten mit Betriebsrat oder Personalvertretung der zwingenden Mitbestimmung unterliegt und deshalb durch Kollektivvereinbarung zu regeln ist und unter welchen Voraussetzungen Risikotrager als leitende Angestellte qualifiziert werden koennen. Die Mitbestimmung ist aber auch in sachlicher Hinsicht relevant, namlich wenn es um die Ziehung der Grenze geht, welche Abweichungen von aufsichtsrechtlichen Vorgaben aufgrund arbeitsrechtlicher Gegebenheiten hinzunehmen sind. Das essential schliesst mit einem eigenen Kapitel zur aufsichtskonformen Auswahl externer Berater.

One of Americas greatest landscape designers and conservationists, Jensen used native plants to introduce the influential Prairie style of landscape architecture. In " Siftings, "Jensen shares his memories of "wandering in many lands" and his life in the heart of Middle America. His recollections--like his designs--express a love of natural landscapes and regional cultures. As he sifts through a lifetime of ideas about gardens, cities, towns and parks, Jensen makes an eloquent case for a natural style of American landscape.
