Palmiro Togliatti could not have become leader of the Italian Communist Party at a more difficult time in the Party's history. In 1926, while he was away from Italy representing the Party in Moscow, Mussolini's Fascist government outlawed the organisation and arrested all the other leading Communists, including Antonio Gramsci, and Togliatti became leader - but at the cost of living in exile for nearly twenty years.Drawing on unprecedented access to private correspondence and newly available archives, this is the first full biography of this important Communist politician and intellectual. Like many successful politicians, Togliatti was a man of contradictions - the dedicated Party man who was also instrumental in creating the constitution of Republican Italy - whose personal charisma and political acumen kept him at the forefront of Italian politics for nearly forty years. Aldo Agosti explores Togliatti's intellectual development; his achievements and his sometimes criminal mistakes as the leading member of the Comintern; his complex relationship with Moscow; and his lasting impact on Italian politics. The result is a meticulous and fascinating life of one of Western Europe's most successful Communist leaders, which at the same time casts fresh light on the internal politics of the Comintern.
For Solo Violin is a gracefully written, elegiac memoir of childhood."—The Los Angeles Times "An eloquent tribute to [and] a moving account of those who, despite the cruelty of so many around them, found ways to rejoice and trust in the kindness of a few. One is instantly reminded of Life Is Beautiful."—André Aciman, author of Out of Egypt In an extraordinary literary debut, Aldo Zargani reconstructs the lost world of his Jewish childhood during the perilous years 1938–45 when he and his family fled from Fascists and Nazis in northern Italy. His haunting memoir acquires a cinematic intensity as he crosscuts from the blood-red stone spires of Basel, where his father failed to find refuge for his family in 1939, to fiery scenes of the Allied bombing of Turin in 1942, to the freezing winter of 1943–44, which Zargani and his brother spent hidden in a Catholic boarding school deep in the countryside. For Solo Violin is filled with colorful portraits of Italian aristocrats and peasants, priests and soldiers, teachers and students, informers and partisans. At its heart is Zargani's vivid depiction of his father, a concert violinist forced to give up his career when the Fascists came to power. In this time of persecution, the Zargani family survived through their own resourcefulness and through the efforts of the many Italians who came to their aid, from the young doctor who helped them escape from Turin to the shepherd who supplied them with milk during the last year of the war, when they lived among the partisans in a remote Piedmont valley. Looking back over a distance of fifty years, Zargani rediscovers the enchantment of childhood shining in "fable-like constellations" even amidst the inferno of war. Lullabies and school games, fairy tales and family jokes are interwoven with the events of terror and oppression. Lyrical, humorous, tender, and wise, For Solo Violin is a testament to resilience and hope during the darkest period in human history. "A broad panorama of Italian-Jewish history in [the last] century. Elegant in its style and, however tragic, also rich with understatement, irony, and wit, For Solo Violin counts among the great, enduring works of art."—Focus Magazine, Germany "A tragic, deeply engaging, delicious book—yes delicious, too. (Reading it makes you smile.) It's a miracle…It makes one think of the wit of Kafka!"—L'Espresso, Italy "Zargani depicts a wealth of sad, despairing, but often also incredibly funny episodes…But vibrating along with the humor is always the sense of threat, and behind it opens the abyss of terror."—Neue Zürcher Zeitung, Switzerland
Mobile data subscriptions are expected to more than double and mobile wireless traffic to increase by more than tenfold over the next few years. Proliferation of smart phones, tablets, and other portable devices are placing greater demands for services such as web browsing, global positioning, video streaming, and video telephony. Many of the proposed solutions to deal with these demands will have a significant impact on antenna designs. Antennas with frequency agility are considered a promising technology to help implement these new solutions. This book provides readers with a sense of the capabilities of frequency-agile antennas (FAAs), the widely diverse methods for achieving tunability, the current achievable performance, and the challenges still facing FAA designs. This resource explores the many aspects of FAAs, including an examination of the metrics used to evaluate their performance, a review of the most commonly used antenna elements, an in-depth look at the wide variety of mechanisms for achieving tunability, and a comprehensive survey of diverse examples of FAA designs. The focus is on FAAs for wireless mobile communications with applications including handsets, laptops, wireless machine-to-machine communications, as well as larger, fixed designs such as cellular base station antennas.
Herodotus, one of the earliest and greatest of Western prose authors, set out in the late fifth century BC to describe the world as he knew it. This commentary by leading scholars, originally published in Italian, has been fully revised by the original authors and is now presented for English readers.
Transitions from the innermost shells of iron, especially the K- and L-shelllines, provide a powerful tool for probing the physical characteristics of hot plasmas in X-ray sources. Their strength and purity allow important conclusions to be drawn even with modest energy resolution. They should also help in studying the regions around black holes and neutron stars. In this book the state of the art and themost recent theoretical and experimental observations are presented. The book will be a valuable source for future satellite missions. It addresses both researchers and graduate students in astrophysics.
