A focus on learning GIS through 16 real world case studies. An introduction to an open-source software that can be used beyond the classroom. Analyzes Sustainable Development Goals in a global framework and provides an alternative approach to learning GIS. Supports both secondary and tertiary educators and improves GIS education at all levels. Contains a holistic range of case studies that extend across several disciplines, from geography education, environmental sciences, geosciences, natural sciences, social sciences, and digital humanities.

Electron-emissive materials are poised to improve device performance when physical size, weight, power consumption, beam current, and/or high pulse repetition frequencies are an important issue for competitive performance. Cold cathodes offer potential property improvements over conventional thermionic sources - instant on/off performance, high brightness, high-current density, large transconductance-to-capacitance ratio, or low-voltage operation characteristics. Many extraordinary technologies are developing, some well known, and some new to the electron sources scene. Flat-panel displays are undoubtedly the largest commercial endeavor to which cold cathode source technology is being directed. Advanced microwave power tubes are one of the most technically challenging applications pursued. Other important applications with considerable impact include electron sources for micropropulsion systems and tethers for satellites. Small and stable sources are needed for multibeam lithography, electron microscopes, and other high-tech tools and applications. This book contains papers from two symposia held during the 2000 MRS Spring Meeting in San Francisco, all brought together to provide a single comprehensive profile of this dynamic and still advancing field.

May and Jack first met on the London Underground; both were students travelling to King's College from their homes in Forest Gate at the very east end of London. Their friendship grew as they discovered their many common interests; "poetry, social conditions, human motives and the many topics that have concerned students over the centuries," as May put it. They began writing letters to each other as well as meeting regularly, and soon realized they had fallen in love. However this was 1914, and Europe was on the brink of war. Jack joined the Territorial Army and by the time war was declared he was already training to become a 2nd Lieutenant, a subaltern. He continued to write to May during his training, and from the trenches of war-torn France, where he was injured by a sniper, until he received fatal injuries while scouting in no-man's-land. This book tells the story of this doomed love affair through excerpts from May's memoirs, Jack's writings and sketches and above all through Jack's letters to May.
