 Free Download Piezo-Electric Electro-Acoustic Transducers by Valeriy Sharapov , Zhanna Sotula , Larisa Kunickaya English | PDF (True) | 2014 | 232 Pages | ISBN : 3319011979 | 13.2 MB Electroacoustic transducers (EAT) are devices, which transform electric energy to energy of acoustic fluctuations. Principles of action, design of transducers for work in air and water as well as for non-destructive control are described in the book. New technologies of designing EAT, not only expanding designing possibilities, are described. They also allow to create transducers with improved characteristics. In particular, methods to increase target capacity (sound pressure), decrease working (resonant) frequency of transducers and expand frequencies of projectors and sound receivers are developed. Methods and control units of transducers in batch production of transducers are described, too.

Free Download Physics of Transition Metal Oxides by Sadamichi Maekawa , Takami Tohyama , Stewart E. Barnes , Sumio Ishihara , Wataru Koshibae , Giniyat Khaliullin English | PDF | 2004 | 345 Pages | ISBN : 3540212930 | 34.4 MB The fact that magnetite (Fe304) was already known in the Greek era as a peculiar mineral is indicative of the long history of transition metal oxides as useful materials. The discovery of high-temperature superconductivity in 1986 has renewed interest in transition metal oxides. High-temperature su perconductors are all cuprates. Why is it? To answer to this question, we must understand the electronic states in the cuprates. Transition metal oxides are also familiar as magnets. They might be found stuck on the door of your kitchen refrigerator. Magnetic materials are valuable not only as magnets but as electronics materials. Manganites have received special attention recently because of their extremely large magnetoresistance, an effect so large that it is called colossal magnetoresistance (CMR). What is the difference between high-temperature superconducting cuprates and CMR manganites? Elements with incomplete d shells in the periodic table are called tran sition elements. Among them, the following eight elements with the atomic numbers from 22 to 29, i. e. , Ti, V, Cr, Mn, Fe, Co, Ni and Cu are the most im portant. These elements make compounds with oxygen and present a variety of properties. High-temperature superconductivity and CMR are examples. Most of the textbooks on magnetism discuss the magnetic properties of transition metal oxides. However, when one studies magnetism using tradi tional textbooks, one finds that the transport properties are not introduced in the initial stages.  Free Download Physics of Meteoric Phenomena by V. A. Bronshten English | PDF | 1983 | 373 Pages | ISBN : 9027716544 | 49 MB "Meteoric phenomena" is the accepted term for the complex of physi cal phenomena that accompany the entry of meteoric bodies into the at mosphere of the earth (or of any planet). "Meteoric bodies" are usually defined as cosmic bodies observed by optical or radar techniques, when they enter the atmosphere. The limiting sensitivity of present-day radar equipment makes it possible to record meteors of up to stellar magnitude +14, while the most brilliant bolides may reach magnitude -19. On a mass 7 7 scale this corresponds approximately to a range of 10- to 10 g. How ever, met~or astronomy is also concerned with larger objects, namely crater-forming meteorites, or objects that cause large-scale destruction when they arrive through the atmosphere (an example is the Tunguska River meteorite). Consideration of the interaction of such objects with 12 the terrestrial atmosphere extends the mass range to 10 g. On the other hand, scientists studying fragmentation processes in meteoric bod 7 ies have to consider particles with masses less than 10- g, and the use of data from meteoric-particle counters on rockets and artificial satel lites, from microcraters on the lunar surface, and from noctilucent clouds 12 lowers the minimum mass to 10- g. Therefore, the mass range of meteoric bodies, or meteoroids, encompasses 24 orders of magnitude. Although recent years have witnessed considerable development in meteor research, both in the Soviet Union and elsewhere, the main mono graphs on meteor physics were published twenty or more years ago.  Free Download Physical Processes in Solar Flares by Boris V. Somov English | PDF | 1992 | 255 Pages | ISBN : 0792312619 | 24 MB Solar flares are very complex electromagnetic phenomena of a cataclysmic nature. Particles are accelerated to very high velocities and a variety of physical processes happen inside and outside flares. These processes can be studied by a large number of techniques from Earth and from space. The aim is to discover the physics behind solar flares. This goal is complicated because information about the flare mechanism can be obtained only in an indirect way by studying the secondary effects.  Free Download Photomechanics by Pramod K. Rastogi English | PDF (True) | 2000 | 485 Pages | ISBN : 3662309475 | 18.9 MB Photomechanics describes the use of photonics techniques for the nondestructive measurement of variations in certain important physical quantities such as displacements, strains, densities, etc. in experimental solid mechanics and flow.

Free Download Philosophy, its History and Historiography by A. J. Holland English | PDF | 1985 | 335 Pages | ISBN : 9027719454 | 33 MB The Royal Institute of Philosophy has been sponsoring conferences in alternate years since 1969. These have from the start been intended to be of interest to persons who are not philosophers by profession. They have mainly focused on interdisciplinary areas such as the philosophies of psychology, education and the social sciences. The volumes arising from these conferences have included discussions between philosophers and distinguished practitioners of other disciplines relevant to the chosen topic. Beginning with the 1979 conference on 'Law, Morality and Rights' and the 1981 conference on 'Space, Time and Causality' these volumes are now constituted as a series.  Free Download Pharmaceutical Microscopy by Robert Allen Carlton English | PDF | 2011 | 332 Pages | ISBN : 1441988300 | 9.8 MB Microscopy plays an integral role in the research and development of new medicines. Pharmaceutical Microscopy describes a wide variety of techniques together with numerous practical applications of importance in drug development. The first section presents general methods and applications with an emphasis on the physical science aspects. Techniques covered include optical crystallography, thermal microscopy, scanning electron microscopy, energy dispersive x-ray spectrometry, microspectroscopy (infrared and Raman), and particle size and shape by image analysis. The second section presents applications of these techniques to specific topics of pharmaceutical interest, including studies of polymorphism, particle size and shape analysis, and contaminant identification. Pharmaceutical Microscopy is designed for those scientists who must use these techniques to solve pharmaceutical problems but do not need to become expert microscopists. Consequently, eachsection has exercises designed to teach the reader how to use and apply the techniques in the book. Although the focus is on pharmaceutical development, workers in other fields such as food science and organic chemistry will also benefit from the discussion of techniques and the exercises. |
