The field of electrets has developed rapidly with an increasing number of new materials, methods for investigating charge-storage phenomena, and the development of creative and exciting applications. This third edition of Electrets, printed in two volumes, documents the significant contributions to the knowledge and understanding of the field. Vol. 1: Reprint of the 1987 second edition with updates and corrections. This volume covers all the basics plus the important research from 1920 to 1987. Vol. 2: Six chapters on the hot topics in electrets providing a digest of the significant progress in electret research over the 11 years since the 1987 publication of the second edition. This compendium is based on special issues of the IEEE Transactions on Dielectrics and Electrical Insulation, with further extensive updates by each contributor. Although there have been monographs and proceedings of conferences published on this topic, there had been no cohesive treatment of the entire field of electrets until the original publication of Dr. Sessler's seminal work, Electrets, first edition. Now he and his colleagues, plus younger colleagues who bring a fresh perspective, continue to contribute and update the series by offering this latest comprehensive survey of noteworthy developments in the field of electrets.

Diploma Thesis from the year 2005 in the subject Business economics - Marketing, Corporate Communication, CRM, Market Research, Social Media, grade: 1,3, University of Paderborn (Chair of Business English), 76 entries in the bibliography, language: English, abstract: For almost ten years, the Internet, a global data network, has been an open medium for public use, leading to a closer relationship between producers and customers. This relationship is the result of the two main characteristics of the Internet: on the one hand it offers new ways of communicating, while also developing new channels of distribution. As more or less all companies and a large number of private households have access to the Internet, the field of marketing has expanded - and the so called "Internet Marketing" is more important than ever before. Even everyday radio- and TV-spots mention links in the Internet inviting the customer to visit their owner's website. These websites are used either to present the companies themselves or to present the companies' products and to sell or distribute them online. The success of a company's online offers depends on different factors: attraction of the offerings, optimized pricing, appropriate measures to reach the target group, focus on target group and promotion. Here the question comes up: which measures can be taken to ensure potential customers are attracted to a particular website? One of the main activities of users is the so-called "browsing" - the search for information in the World Wide Web. The specific search for this information can be done through the use of search engines such as Google, Yahoo or Fireball. This thesis will explain and work out how to use different types of search engines, platforms and pay-per-view-portals to optimize a company's marketing (exposure to target audience).
