Magnetoresistance is an effect associated with the change of the quanta of the magnetic field due to the energy emission by the atom. In this book, Chapter One discusses magnetoresistive multilayers using various iron oxides and their characteristics. Chapter Two examines magnetoresistance connected with quantum electron transitions in the hydrogen atom. Chapter Three focuses on giant injection magnetoresistance in ferromagnet/semiconductor heterostructures.

Planning and implementing a 3D printing service in a library may seem like a daunting task. Based upon the authors' experience as early adopters of 3D technology and running a successful 3D printing service at a large academic library, this guide provides the steps to follow when launching a service in any type of library. Detailed guidance and over 50 graphics provide readers with sage guidance and detailed instructions on: *planning a proposal *printer selection tips *preparing the location *addressing staff concerns for new service *developing service workflows and procedures *managing inevitable disasters *developing policies *conducting the "reference interview" for 3D printing *staff training tips *outreach activities This book brings into one place all the guidance you need for developing and implementing a 3D printing service in any library.
