Book Description
The purpose of this book is to share collective experience on human spaceflight operations. For the many authors, this is nothing less than a work of passion. They are sharing their life's work with the goal of passing on their experience to the next generation of space engineers, designers, operators, and crew.

Book Description
This book contains selected papers prepared for the NATO Advanced Study Institute on "Unsteady Combustion", which was held in Praia da Granja, Portugal, 6-17 September 1993. Approximately 100 delegates from 14 countries attended. The Institute was the most recent in a series beginning with "Instrumentation for Combustion and Flow in Engines", held in Vimeiro, Portugal 1987 and followed by "Combusting Flow Diagnostics" conducted in Montechoro, Portugal in 1990. Together, these three Institutes have covered a wide range of experimental and theoretical topics arising in the research and development of combustion systems with particular emphasis on gas-turbine combustors and internal combustion engines. The emphasis has evolved roughly from instrumentation and experimental techniques to the mixture of experiment, theory and computational work covered in the present volume. As the title of this book implies, the chief aim of this Institute was to provide a broad sampling of problems arising with time-dependent behaviour in combustors. In fact, of course, that intention encompasses practically all possibilities, for "steady" combustion hardly exists if one looks sufficiently closely at the processes in a combustion chamber. The point really is that, apart from the excellent paper by Bahr (Chapter 10) discussing the technology of combustors for aircraft gas turbines, little attention is directed to matters of steady performance. The volume is divided into three parts devoted to the subjects of combustion-induced oscillations; combustion in internal combustion engines; and experimental techniques and modelling.

Book Description
The time of Carnival represents a "wild" time at the end of winter and pointing to the beginning of a new season. It is characterized by the irruption of border figures, animal masks, characters which recall the world of the dead and which bring within themselves the germ of a vital force, of the energy that produces the reawakening of nature and announces the growth and fertility of the new crops. This wild domain shows itself under the shapes of a contiguity between human and animal: the costumes, the masks, refer to a world in which the characteristics of the human and those of the animal are fused and intertwined. Among these figures, in particular, emerge those of the Wild Man, the human being who takes on animal-like attributes and aspects, and of the Bear, the animal that, more than all the others, gets as close as possible to the human and seems to reflect a deformed image of it. Such symbolic images come from far off times and places to tell a story that belongs to our common origins. The bear assumes attributes and functions alike in very different cultural contexts, such as the Sámi of Finland or North-American hunter-gatherers, and represents a boundary between the world of nature and the human world, between the domain of animals and the difficult construction of humanity: a process continued for centuries, perhaps millennia, and which cannot still be said complete.

Book Description
The theory of natural pedagogy provides a model of social learning based on the direct communicative ostensive relation and aimed to the transfer of generic cultural knowledge. The pedagogical transmission of information originates from an explicit manifestation of teaching made by knowledgeable adults, who are naturally inclined to manifestly provide their cultural baggage to naïve conspecifics. The domain of transferable knowledge encompasses artifact functions, novel means actions, first words, gestural symbols, social practices, and rituals. This teaching process can be fast and efficient in virtue of a natural inclination possessed by infants to seek information and decode signals of ostensive communication. In this sense, the natural pedagogy represents, as the two proponents – György Gergey and Gergely Csibra – claim, «a communicative system of mutual design specialized for the fast and efficient transfer of new and relevant cultural knowledge from knowledgeable to ignorant conspecifics». This book suggests that natural pedagogy utilises early belief attribution competences, which are employed by infants in a variety of contexts to approach and navigate the social world. Therefore, the natural pedagogy, in cooperation with the early mindreading system, may represent one of the most efficient adaptive strategies to firmly create that deep wittgensteinian «nest of propositions» which build cultural shared beliefs structures to be relied upon and followed.
