 Free Download Pigmented Ethnic Skin and Imported Dermatoses: A Text-Atlas by Constantin E. Orfanos English | EPUB | 2018 | 515 Pages | ISBN : 3319694219 | 485 MB The vast majority of the global population has pigmented non-Caucasian skin; accordingly, this book focuses on the diagnosis and management of skin diseases in dark-skinned populations, paying particular attention to different reactive profiles, the frequency and the clinical pictures of diseases in pigmented ethnic skin that arise in hot climate zones.  Free Download Piezoelectric Sensorics: Force Strain Pressure Acceleration and Acoustic Emission Sensors Materials and Amplifiers by Gustav Gautschi English | PDF(True) | 2002 | 271 Pages | ISBN : 3540422595 | 24.3 MB Sensors are the key to life and survival - and to the success of modern technology. Nature has provided living creatures with a wealth of sensors for a variety of measurands, such as light, sound, temperature, speed, motion, distance, force, pressure, acceleration, odor and so on - sensors, whose performance and specifications have often not been matched yet by man-made devices. Even at today's high level of electronics and information technology, sensors remain the crucial and decisive interface needed to reliably relate phenomena occurring in the environment to corresponding electric signals that can be processed to obtain the desired information and subsequent correct reaction of systems. Although the literature on sensors is extremely vast, there is one type of sensors which so far has received little attention: the piezoelectric sensor. Certainly, most handbooks on measurement mention briefly this type of sensor yet there is not a single book in the English language dedicated entirelyto piezoelectric sensors and giving a reasonably complete overview. There are only the books by [Gohlke 1955 and 1959] and [Tichy and Gautschi 1980], all in German.  Free Download Physics of Quantum Well Devices by B. R. Nag English | PDF | 2000 | 309 Pages | ISBN : 1402003609 | 6.7 MB Quantum well devices have been the objects of intensive research during the last two decades. Some of the devices have matured into commercially useful products and form part of modern electronic circuits. Some others require further dev- opment, but have the promise of being useful commercially in the near future. Study of the devices is, therefore, gradually becoming compulsory for electronics specialists. The functioning of the devices, however, involve aspects of physics which are not dealt with in the available text books on the physics of semicond- tor devices. There is, therefore, a need for a book to cover all these aspects at an introductory level. The present book has been written with the aim of meeting this need. In fact, the book grew out of introductory lectures given by the author to graduate students and researchers interested in this rapidly developing area of electron devices. The book covers the subjects of heterostructure growth techniques, band-offset theory and experiments, electron states, electron-photon interaction and related phenomena, electron transport and the operation of electronic, opto-electronic and photonic quantum well devices. The theory as well as the practical aspects of the devices are discussed at length. The aim of the book is to provide a comprehensive treatment of the physics underlying the various devices. A reader after going through the book should find himself equipped to deal with all kinds of quantum well devices.  Free Download Physical and Mathematical Modeling of Earth and Environment Processes-2022: Proceedings of 8th International Scientific Conference-School for Young Scientists by V. I. Karev English | EPUB | 2023 | 626 Pages | ISBN : 3031259610 | 124.9 MB The book presents short papers of participants of the 8th International Scientific Conference-School for Young Scientists "Physical and Mathematical Modeling of Earth and Environment Processes" (Ishlinsky Institute for Problems in Mechanics of the Russian Academy of Sciences). The book includes theoretical and experimental studies of processes in the atmosphere, oceans, the lithosphere and their interaction; environmental issues; problems of human impact on the environment; methods of geophysical research.  Free Download Physical Chemistry of, in and on Silicon by Gianfranco Cerofolini , Laura Meda English | PDF | 1989 | 130 Pages | ISBN : 3642735061 | 9.4 MB The aim of this book is twofold: it is intended for use as a textbook for a ~ourse on electronic materials (indeed, it stems from a series of lectures on this topic delivered at Milan Polytechnic and at the universities of Modena and Parma), and as an up-to-date review for scientists working in the field ::>f silicon processing. Although a number of works on silicon are already available, the vast amount of existing and new data on silicon properties are nowhere adequately summarized in a single comprehensive report. The present volume is intended to fill this gap. Most of the examples dealt with are taken from the authors' every day experience, this choice being dictated merely by their greater knowl edge of these areas. Certain aspects of the physics of silicon have not been included; this is either because they have been treated in standard textbooks (e.g. the inhomogeneously doped semiconductor and the chem istry of isotropic or preferential aqueous etching of silicon), or because they are still in a rapidly evolving phase (e.g. silicon band-gap engineering, generation-recombination phenomena, cryogenic properties and the chem istry of plasma etching). In line with the standard practice in microelectronics, CGS units will be used for mechanical and thermal quantities, and SI units for electrical quan tities. All atomic energies will be given in electronvolts and the angstrom will be the unit of length used for atomic phenomena.  Free Download Petrified: Living During a Rupture of Life on Earth English | 2025 | ISBN: 3111381730 | 374 Pages | PDF EPUB (True) | 85 MB A rupture of life on Earth is currently unfolding. What, then, does this rupture signify, not only in terms of being alive during such an upheaval, but also in terms of being alive to upheaval itself? Petrified: Living During a Rupture of Life on Earth takes the reader on a journey deep into the nature of our home, to give us the tools to learn how, in the middle of that rupture, to comport ourselves with honesty, clarity, culpability and intelligence.  Free Download Peri-Implant Complications: A Clinical Guide to Diagnosis and Treatment by Anastasia Kelekis-Cholakis English | PDF,EPUB | 2018 | 122 Pages | ISBN : 3319637177 | 101.21 MB This book is an up-to-date reference that provides detailed guidance on how to diagnose and manage the soft and hard tissue complications that may be associated with a functioning dental implant placement, such as peri-implant mucositis, soft tissue loss, and peri-implantitis.
