This book addresses the key concerns regarding the operation of wind turbines in cold climates and focuses in particular on the analysis of icing and methods for its mitigation. Topics covered include the implications of cold climates for wind turbine design and operation, the relevance of icing for wind turbines, the icing process itself, ice prevention systems and thermal anti-icing system design. In each chapter, care is taken to build systematically on the basic knowledge, providing the reader with the level of detail required for a thorough understanding. An important feature is the inclusion of several original analytical and numerical models for ready computation of icing impacts and design assessment. The breadth of the coverage and the in-depth scientific analysis, with calculations and worked examples relating to both fluid dynamics and thermodynamics, ensure that the book will serve not only as a textbook but also as a practical manual for general design tasks.
To Return to Cuba" is the riveting true story of the author's experiences as a teenager during the Cuban Revolution. He shares rare, first-hand accounts of the Bay of Pigs and the Missile Crisis from his point of view as a Cuban revolutionary soldier, and personal experiences with Fidel Castro at the University of Havana. As a Cuban student studying in Hungary, his views of the revolution evolve, forcing him to attempt a harrowing escape from Castro, Cuba and Communism.
Cultural factors shape the symbolic environment in which contentious politics take place. Among these factors, collective memories are particularly relevant: they can help collective action by providing symbolic material from the past, but at the same time they can constrain people's ability to mobilise by imposing proscriptions and prescriptions. This book analyses the relationship between social movements and collective memories: how do social movements participate in the building of public memory? And how does public memory, and in particular the media’s representation of a contentious past, influence strategic choices in contemporary movements? To answer these questions the book draws its focus on the evolution of the representation of specific events in the Italian and Spanish student movements of the 1960s and 1970s. Furthermore, through qualitative interviews to contemporary student activists in both countries, it investigates the role of past waves of contention in shaping the present through the publicly discussed image of the past.
The book explores current characteristics of the urban built environment in view of possible future transformations. A cross-reading analysis of existing public social housing buildings is proposed, based on the investigation of their architectural, structural, and energetic characteristics. The study aims to provide an integrated approach that captures the link between typology, construction, and energy demands, offering a key to understanding the main critical issues and transformation readiness. It focuses on large-scale interventions composing public social housing stocks, realized during the second half of the twentieth century. More than other public interventions, such building stocks clearly lack in meeting current housing needs such as modern apartment architectural layout, energy and structural regulations, and social mix. However, due to their numerical presence, strategical and widespread distribution across urban areas, and transformability, these buildings can be the target for future strategic regeneration projects. In particular, the book thoroughly investigates the social housing estate constructed in Rome (Italy) after the approval in 1964 of the first urban economic and social housing plan.

This study of the Venetian artist Lorenzo Lotto draws on the large body of work by the artist, as well as on the 16th-century documentation on the artist's life, including letters, an account book for the years 1538-56, and will.
