Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
Book Synopsis Quaternary Vegetation Dynamics by : Jürgen Runge
Download or read book Quaternary Vegetation Dynamics written by Jürgen Runge and published by CRC Press. This book was released on 2021-11-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.
Download or read book Sagalassos I written by Marc Waelkens and published by Leuven University Press. This book was released on 1993 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sagalassos, once the metropolis of the Western Taurus range (Pisidia, Turkey), was only thoroughly surveyed in 1884 and 1885 by an Austrian team directed by K. Lanckoronski. In 1986-1989 this work was resumed by a British-Belgian team co-directed by Dr. Stephen Mitchell (University College of Swansea) and by Prof. Dr. Marc Waelkens (Catholic University of Leuven). In 1990 Sagalassos became a full scale Belgian project and a leading center for interdisciplinary archaeological and archaeometrical research. Due to its altitude, the site is one of the best preserved towns from classical antiquity, with a rich architectural and sculptural tradition dating from the second century BC to the sixth century AD. From early Imperial times until the early Byzantine period a complete range of coarse and red slip wares was produced locally. Excavations are concentrated on the upper and lower agoras to document the political and commercial life in the town and also in the area where a late Hellenistic fountain house, which still functions to date, and a Roman library were discovered. Major efforts are undertaken to restore the excavated monuments in their old glory. Several disciplines integrate the town again within its ancient environment and document the central role which Sagalassos played in the area.

Book Synopsis Infrared and Raman Spectroscopy of Lunar and Terrestrial Minerals by : Clarence Karr
Download or read book Infrared and Raman Spectroscopy of Lunar and Terrestrial Minerals written by Clarence Karr and published by Elsevier. This book was released on 2013-10-22 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared and Raman Spectroscopy of Lunar and Terrestrial Minerals makes available in a single reference work original descriptions and summaries of the research on infrared and Raman spectroscopy of lunar and terrestrial minerals so that this information will be readily available not only to those researchers in the continuing programs on lunar samples from the completed Apollo series and on the remote sensing of solar system objects, but, in particular, to that much larger group of researchers in government, industry, and universities involved in the many programs on terrestrial minerals and earth sciences by remote sensing. The chapters in this volume are arranged according to spectroscopic technique and/or frequency range rather than application. Thus there are chapters on visible and near-infrared, followed by those on mid-infrared, far-infrared, and Raman spectroscopy. Applications are roughly divided between lunar and terrestrial, although the broad range of interchangeability of applications is obvious in many instances. There are also chapters on remote sensing of space targets and earth sciences; on lunar mineralogy and terrestrial mineralogy and geology; and on structures of lunar minerals and structures of terrestrial minerals.
Book Synopsis Atom movements - Diffusion and mass transport in solids by : Jean-Marc Philibert
Download or read book Atom movements - Diffusion and mass transport in solids written by Jean-Marc Philibert and published by EDP Sciences. This book was released on 2012-12-03 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book is the result of diverse courses on diffusion. It is intended to give as complete an overview as possible of diffusion in solid media, while relating the process of diffusion to both their physical bases and their applications. A series of a real situations is covered in this account, from self-diffusion of radiotracers to the more complex cases of mass flow under chemical or thermal gradients or under electric fields, or diffusion in structures of lower dimensionality (surfaces and interfaces). In all these analyses, no category of materials was favored; metals, ionic crystals, oxydes, and semiconductors all had their turn. Only polymers were not specifically touched. One chapter is specifically devoted to techniques for studying diffusion, including methods of numerical simulation, and a last and long chapter gives a number of metallurgical phenomena in which diffusion plays a fundamental role.

Book Synopsis Science and Archaeology by : Robert H. Brill
Download or read book Science and Archaeology written by Robert H. Brill and published by Mit Press. This book was released on 2003-02-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: If they share one common theme, these collected papers clearly indicate the directions of current research in archaeological chemistry--a term that, taken in a broad sense, includes techniques and methodologies of many areas of science other than chemistry. Dr. Brill, in fact, advocates use of the term "archaeometry" (coined by Dr. E. T. Hall of Oxford University) to describe more accurately the work of quite a few investigators in the field.Twenty-one chapters by distinguished contributors are organized in three main categories according to research objectives. Part One contains investigations of individual objects or small groups of objects, describing how they were made and their places in the early history of technology or science. Studies in Part Two consist of analyses of such diverse materials as metals, pottery, ob- sidian, and amber to uncover patterns of chemical composition for the classification of fragments according to provenance or date. A number of chapters in this section deal with neutron-activation analysis. The book's final part describes four techniques used for dating archaeological objects.The volume is generous in scope, ranging over a variety of approaches and motivations, research tools, and archaeological materials. Some of the more technically advanced studies cover up-to-date and complex instrumentation for analyzing samples more accurately, more rapidly, and with greater convenience than before, while others emphasize the detailed handling or "autopsy" of the objects themselves. The material in this book was originally prepared for the Fourth Symposium on Archaeological Chemistry, sponsored by the Division of the History of Chemistry of the American Chemical Society in 1968.Dr. Brill cites several problems that should form the basis for further research: the criteria for selecting what is necessary and significant from increasingly unwieldy bodies of data; the means by which findings in this field can be used in a more than descriptive manner to reveal something new about early man; and the continued necessity for close cooperation between the archaeometrist and archaeologist. The former, Dr. Brill points out, must take a major part in interpreting his findings and not merely leave his tabulations and statistical correlations to the historian and archaeologist.
Book Synopsis Sampling in Archaeology by : Clive Orton
Download or read book Sampling in Archaeology written by Clive Orton and published by Cambridge University Press. This book was released on 2000-05-11 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first overview of sampling for archaeologists for over twenty years, this manual offers a comprehensive account of the applications of statistical sampling theory which are essential to modern archaeological practice at a range of scales, from the regional to the microscopic. Bringing archaeologists up to date with an aspect of their work which is often misunderstood, it includes a discussion of the relevance of sampling theory to archaeological interpretation, and considers its fundamental place in fieldwork and post-excavation study. It demonstrates the vast range of techniques that are available, only some of which are widely used by archaeologists. A section on statistical theory also reviews latest developments in the field, and the formal mathematics is available in an appendix, cross-referenced with the main text.
Book Synopsis Pottery and People by : James M. Skibo
Download or read book Pottery and People written by James M. Skibo and published by University of Utah Press. This book was released on 1999-01-14 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume emphasizes the complex interactions between ceramic containers and people in past and present contexts. Pottery, once it appears in the archaeological record, is one of the most routinely recovered artifacts. It is made frequently, broken often, and comes in endless varieties according to economic and social requirements. Moreover, even in shreds ceramics can last almost forever, providing important clues about past human behavior. The contributors to this volume, all leaders in ceramic research, probe the relationship between humans and ceramics. Here they offer new discoveries obtained through traditional lines of inquiry, demonstrate methodological breakthroughs, and expose innovative new areas for research. Among the topics covered in this volume are the age at which children begin learning pottery making; the origins of pottery in the Southwest U.S., Mesoamerica, and Greece; vessel production and standardization; vessel size and food consumption patterns; the relationship between pottery style and meaning; and the role pottery and other material culture plays in communication. Pottery and People provides a cross-section of the state of the art, emphasizing the complete interactions between ceramic containers and people in past and present contexts. This is a milestone volume useful to anyone interested in the connections between pots and people.
Book Synopsis Mesoamerica's Classic Heritage by : David Carrasco
Download or read book Mesoamerica's Classic Heritage written by David Carrasco and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a millennium the great Mesoamerican city of Teotihuacan (c. 150 B.C.E. - 750 C.E.) has been imagined and reimagined by a host of subsequent cultures, including our own. Mesoamerica's Classic Heritage engages the subject of the unity and diversity of pre-Hispanic Mesoamerica by focusing on the classic heritage of this ancient city. This new volume is the product of several years of research by members of Princeton University's Moses Mesoamerican Archive and Research Project and Mexico's Proyecto Teotihuacán. Offering a variety of disciplinary perspectives - including the history of religions, anthropology, archaeology, and art history - and a wealth of new data, Mesoamerica's Classic Heritage examines Teotihuacan's rippling influence across Mesoamerican time and space, including important patterns of continuity and change, and its relationships, both historical and symbolic, with Tenochtitlan, Cholula, and various Maya communities. The contributors to Mesoamerica's Classic Heritage offer a wide range of individual interpretations, but they agree that Teotihuacan, more than any other pre-Hispanic center, was a paradigmatic source that formed the art and architecture, cosmology and ritual life, and conceptions of urbanism and political authority for significant parts of the Mesoamerican world. This great city achieved the prestige of being the site of the creation of the cosmos and of effective social and political space in Mesoamerica through its capacity to symbolize, perform, and export its imperial authority. These essays reveal the different ways in which Teotihuacan's classic heritage both fed and fed on the dynamic interactivity of the entire area. Whether or not a paradigm shift in Mesoamerican studies is taking place, certainly a new contextual understanding of Teotihuacan and the diversities and unities of Mesoamerica is emerging in these pages.

Book Synopsis The Maya and Teotihuacan by : Geoffrey E. Braswell
Download or read book The Maya and Teotihuacan written by Geoffrey E. Braswell and published by University of Texas Press. This book was released on 2009-07-21 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributors to this volume present extensive new evidence from archaeology, iconography, and epigraphy to offer a more nuanced understanding of the interaction between the Early Classic Maya and Teotihuacan. Winner, Choice Outstanding Academic Book, 2005 Since the 1930s, archaeologists have uncovered startling evidence of interaction between the Early Classic Maya and the great empire of Teotihuacan in Central Mexico. Yet the exact nature of the relationship between these two ancient Mesoamerican civilizations remains to be fully deciphered. Many scholars have assumed that Teotihuacan colonized the Maya region and dominated the political or economic systems of certain key centers—perhaps even giving rise to state-level political organizations. Others argue that Early Classic rulers merely traded with Teotihuacan and skillfully manipulated its imported exotic goods and symbol sets to increase their prestige. Moving beyond these traditional assumptions, the contributors to this volume present extensive new evidence from archaeology, iconography, and epigraphy to offer a more nuanced understanding of the interaction between the Early Classic Maya and Teotihuacan. Investigating a range of Maya sites, including Kaminaljuyu, Copán, Tikal, Altun Ha, and Oxkintok, they demonstrate that the influence of Teotihuacan on the Maya varied in nature and duration from site to site, requiring a range of models to explain the patterns of interaction. Moreover, they show that the interaction was bidirectional and discuss how the Maya in turn influenced Teotihuacan.
