This book investigates the adsorption dynamics of water, methanol, ethanol, and ammonia vapor on loose and consolidated adsorbent beds, as well as the impact of this aspect on the overall performance of adsorption systems for heat transformation. In particular, it presents the results of kinetic measurements made using the large temperature jump (LTJ) method, the most efficient way to study adsorption dynamics under realistic operating conditions for adsorptive heat transformers. The information provided is especially beneficial for all those working on the development of novel adsorbent materials and advanced adsorbers for heating and cooling applications. Today, technologies and systems based on adsorption heat transformation (AHT) processes offer a fascinating option for meeting the growing worldwide demand for air conditioning and space heating. Nevertheless, considerable efforts must still be made in order to enhance performance so as to effectively compete with commonly used electrical compression and absorption machines. For this purpose, intelligent design for adsorption units should above all focus on finding a convenient choice of adsorbent material by means of a comprehensive analysis that takes into account both thermodynamic and dynamic aspects. While the thermodynamic properties of the AHT cycle have been studied extensively, the dynamic optimization of AHT adsorbers is still an open issue. Several efforts have recently been made in order to analyze AHT dynamics, which greatly influence overall AHT performance.
On the 100th anniversary of the Russian Revolution, the epic story of an enormous apartment building where Communist true believers lived before their destruction The House of Government is unlike any other book about the Russian Revolution and the Soviet experiment. Written in the tradition of Tolstoy's War and Peace, Grossman’s Life and Fate, and Solzhenitsyn’s The Gulag Archipelago, Yuri Slezkine’s gripping narrative tells the true story of the residents of an enormous Moscow apartment building where top Communist officials and their families lived before they were destroyed in Stalin’s purges. A vivid account of the personal and public lives of Bolshevik true believers, the book begins with their conversion to Communism and ends with their children’s loss of faith and the fall of the Soviet Union. Completed in 1931, the House of Government, later known as the House on the Embankment, was located across the Moscow River from the Kremlin. The largest residential building in Europe, it combined 505 furnished apartments with public spaces that included everything from a movie theater and a library to a tennis court and a shooting range. Slezkine tells the chilling story of how the building’s residents lived in their apartments and ruled the Soviet state until some eight hundred of them were evicted from the House and led, one by one, to prison or their deaths. Drawing on letters, diaries, and interviews, and featuring hundreds of rare photographs, The House of Government weaves together biography, literary criticism, architectural history, and fascinating new theories of revolutions, millennial prophecies, and reigns of terror. The result is an unforgettable human saga of a building that, like the Soviet Union itself, became a haunted house, forever disturbed by the ghosts of the disappeared.
