Ion implantation offers one of the best examples of a topic that starting from the basic research level has reached the high technology level within the framework of microelectronics. As the major or the unique procedure to selectively dope semiconductor materials for device fabrication, ion implantation takes advantage of the tremendous development of microelectronics and it evolves in a multidisciplinary frame. Physicists, chemists, materials sci entists, processing, device production, device design and ion beam engineers are all involved in this subject. The present monography deals with several aspects of ion implantation. The first chapter covers basic information on the physics of devices together with a brief description of the main trends in the field. The second chapter is devoted to ion im planters, including also high energy apparatus and a description of wafer charging and contaminants. Yield is a quite relevant is sue in the industrial surrounding and must be also discussed in the academic ambient. The slowing down of ions is treated in the third chapter both analytically and by numerical simulation meth ods. Channeling implants are described in some details in view of their relevance at the zero degree implants and of the available industrial parallel beam systems. Damage and its annealing are the key processes in ion implantation. Chapter four and five are dedicated to this extremely important subject.

Included, the David Bowie studio discography Included a vast collection of magazines front cover
During the Renaissance, measuring played a critical role in shaping trade, material production (ranging from architecture to tailoring), warfare, legal studies, and even our understanding of the heavens and hell. This study delves into the applications of measuring, with a particular emphasis on the Italian states, and traces its wide-ranging cultural effects. The homogeneization of measurements was endorsed as a means to achieve political unity. The careful retrieval of ancient standards instilled a sense of connection and ownership toward the past. Surveying was fundamental in the process of establishing colonies. This study not only examines the perceived advantages of measuring, but it also highlights the overlooked distorting aspect of this activity. Measuring was not just a neutral quantification process but also a creative one. By suppressing or emphasizing information about the material world, measuring influenced people's perceptions and shaped their ideas about what was possible and what could be accomplished.
Cerea, madamin, andoma bin? Less than a century ago, this was one of the most frequent greetings heard in Piedmont, a region in northwest Italy. Today, however, Piedmontese is severely endangered. This volume presents the first widely accessible and comprehensive grammatical description of the contemporary koine, covering its phonetics, phonology, morphology, syntax, pragmatics and typology, and drawing examples from both oral and written sources. Data on the history of the language and the local dialects and notes on revitalization efforts are also included.
It would be difficult to find in the history of the sixteenth century a name more fiercely assailed than that of Gianluigi Fieschi. From Bonfadio down to the most recent historians, the Count of Lavagna has received the same treatment at the hands of our writers which the learned vulgar are accustomed to give to Catiline. This levity of judgment is a new proof that history is too high a pursuit for servile minds...
An interdisciplinary study of hair through the art, philosophy, and science of fifteenth-century Florence. In this innovative cultural history, hair is the portal through which Emanuele Lugli accesses the cultural production of Lorenzo il Magnifico’s Florence. Lugli reflects on the ways writers, doctors, and artists expressed religious prejudices, health beliefs, and gender and class subjugation through alluring works of art, in medical and political writings, and in poetry. He considers what may have compelled Sandro Botticelli, the young Leonardo da Vinci, and dozens of their contemporaries to obsess over braids, knots, and hairdos by examining their engagement with scientific, philosophical, and theological practices. By studying hundreds of fifteenth-century documents that engage with hair, Lugli foregrounds hair’s association to death and gathers insights about human life at a time when Renaissance thinkers redefined what it meant to be human and to be alive. Lugli uncovers overlooked perceptions of hair when it came to be identified as a potential vector for liberating culture, and he corrects a centuries-old prejudice that sees hair as a trivial subject, relegated to passing fashion or the decorative. He shows hair, instead, to be at the heart of Florentine culture, whose inherent violence Lugli reveals by prompting questions about the entanglement of politics and desire.
A traditional radiography is a two-dimensional image of something that actually has three dimensions. At last, thanks to 3D radiological system with a small field of view we have the missing dimension, which exponentially amplifies our knowledge. The CBCT (Cone Beam Computed Tomography) is a real breakthrough for dentistry because it offers many advantages: low radiation dose to patients, high definition with very small voxels, the possibility to see the tooth and the surrounding structures in three different planes, overcoming any anatomical overlapping. It opens a new frontier, and allows us to make precise diagnosis where traditional tools were insufficient. Reading the text we can see the enthusiasm and the passion with which the authors have produced this book. Each chapter is a font of information, every detail has been carefully examined, and each clinical case has been extensively reported. The introductory chapters provide the reader with the knowledge and basic tools to understand the CBCT. Everything else is an atlas, highly enjoyable, which includes the use of CBCT in both clinical and surgical dentistry, and describes in details not only the diagnostic phase but also the operational use to program the individual case, and control the future outcome.
