Ruiz covers a range of festival categories: carnival, royal entries, tournaments, calendrical and noncalendrical celebrations, autos de fe, and Corpus Christi processions. He probes the ritual meanings of these events, paying special attention to the use of colors and symbols, and to the power relations articulated through these festive displays. Ruiz argues that the fluid and at times subversive character of medieval festivals gave way to highly formalized and hierarchical events reflecting a broader shift in how power was articulated in late medieval and early modern Spain. Yet Ruiz contends that these festivals, while they sought to buttress authority and instruct different social orders about hierarchies of power, also served as sites of contestation, dialogue, and resistance.
Microwave tubes are vacuum electron devices used for the generation and amplification of radio frequencies in the microwave range. An established technology area, the use of tubes remains essential in the field today for high-power applications. The culmination of the author's 50 years of industry experience, this authoritative resource offers you a thorough understanding of the operations and major classes of microwave tubes. Minimizing the use of advanced mathematics, the book places emphasis on clear qualitative explanations of phenomena. This practical reference serves as an excellent introduction for newcomers to the field and offers established tube engineers a comprehensive refresher. Professionals find coverage of all major tube classifications, including klystrons, traveling wave tubes (TWTs), magnetrons, cross field amplifiers, and gyrotrons.
The six stories of "A Brief Theory of Travel and the Desert" contemplate the full range of human experience. They take us on a journey around the world, from the arid landscapes of the Mediterranean coast to the work of the brilliant Serbian writer, Milorad Pavic. All of the characters are waiting for, searching for, or exploring the possibility of a revelation which never appears in their numbed here-and-now. However, fate or mere chance (an irrelevant incident, someone fainting on a nudist beach, a plane crash that never actually happened) can reveal in a flash the true face of a character's isolation.
