Non-Universal Superconducting Gap Structure in Iron-Pnictides Revealed by Magnetic Penetration Depth Measurements
by Kenichiro HashimotoIn this book the author presents two important findings revealed by high-precision magnetic penetration depth measurements in iron-based superconductors which exhibit high-transition temperature superconductivity up to 55 K: one is the fact that the superconducting gap structure in iron-based superconductors depends on a detailed electronic structure of individual materials, and the other is the first strong evidence for the presence of a quantum critical point (QCP) beneath the superconducting dome of iron-based superconductors. The magnetic penetration depth is a powerful probe to elucidate the superconducting gap structure which is intimately related to the pairing mechanism of superconductivity. The author discusses the possible gap structure of individual iron-based superconductors by comparing the gap structure obtained from the penetration depth measurements with theoretical predictions, indicating that the non-universal superconducting gap structure in iron-pnictides can be interpreted in the framework of A1g symmetry. This result imposes a strong constraint on the pairing mechanism of iron-based superconductors. The author also shows clear evidence for the quantum criticality inside the superconducting dome from the absolute zero-temperature penetration depth measurements as a function of chemical composition. A sharp peak of the penetration depth at a certain composition demonstrates pronounced quantum fluctuations associated with the QCP, which separates two distinct superconducting phases. This gives the first convincing signature of a second-order quantum phase transition deep inside the superconducting dome, which may address a key question on the general phase diagram of unconventional superconductivity in the vicinity of a QCP.

Non-Wood Forest Products of Asia: Knowledge, Conservation and Livelihood (World Forests #25)
by A. Z. M. Manzoor Rashid Niaz Ahmed Khan Mahmood HossainThis book highlights the importance of non-wood forest products (NWFPs) and their crucial role in sustaining the livelihood of rural and indigenous communities in Asia. The authors depict how the preservation of forests and the associated major non-wood resources may provide an important avenue to reduce poverty. The local practices and knowledge on harvesting NWFPs are often rooted in tradition, and vary from one region to the other. This made it difficult to develop and establish research focus on a greater scale in the past. Readers of this volume will gain an often-missed, broader perspective from these new studies. The authors put a special emphasis on the nexus between conservation and livelihood from an Asian point of view. This addresses a knowledge gap in the current literature and offers important clues on conducting similar research around the world. The volume provides a useful reference guide for the relevant researchers, practitioners and policy makers.
Nonacademic Writing: Social Theory and Technology
by Ann Hill DuinIn this volume, methodological, cultural, technological, and political boundaries felt by writers are analyzed, translated, and challenged in a way that will appeal to researchers, theorists, graduate students, instructors, and managerial audiences. Instead of extracting rules from previous research, the contributors, working from multidisciplinary perspectives, describe and analyze the social and technological contexts surrounding nonacademic writing. Their essays present a formative rather than summative outlook toward future research on nonacademic writing. Collectively, these chapters articulate a unique perspective toward nonacademic writing that considers: * The centrality of emerging communications technologies in nonacademic writing research and the need for a socio-technological perspective. New technologies reshape the concept of text and significantly impact the writing process and written products in nonacademic settings. * The relationship between the academy and the workplace. A number of chapters challenge us -- sometimes from opposing perspectives -- to scrutinize our role as writing educators in preparing students for the workplace. Should we support the interests of corporate employers, or should we resist those interests? Should we enculturate students in workplace writing practices by placing them in these environments, or should we examine the tacit knowledge gained by workplace professionals and deliver this via classroom instruction? * New theory, new research agendas. Contributors from diverse fields offer new theoretical lenses or use established lenses in innovative ways, expanding the agenda for nonacademic writing research. This volume represents the vision the social landscape demands for research and pedagogy in nonacademic writing.
Nonautonomous Bifurcation Theory: Concepts and Tools (Frontiers in Applied Dynamical Systems: Reviews and Tutorials)
by Vasso Anagnostopoulou Christian Pötzsche Martin RasmussenBifurcation theory is a major topic in dynamical systems theory with profound applications. However, in contrast to autonomous dynamical systems, it is not clear what a bifurcation of a nonautonomous dynamical system actually is, and so far, various different approaches to describe qualitative changes have been suggested in the literature. The aim of this book is to provide a concise survey of the area and equip the reader with suitable tools to tackle nonautonomous problems. A review, discussion and comparison of several concepts of bifurcation is provided, and these are formulated in a unified notation and illustrated by means of comprehensible examples. Additionally, certain relevant tools needed in a corresponding analysis are presented.

Noncovalent Functionalization of Carbon Nanotubes
by Claudia BackesIn this thesis, Claudia Backes guides the reader through her multidisciplinary research into the non-covalent functionalization of carbon nanotubes in water. Although one of the most remarkable materials of the 21st century, carbon nanotubes often have limited application because of their intrinsically low solubility and polydispersity. The author shows that rational surfactant design is a powerful tool for chemists because it can unmask the key to solubilization and allow us to tailor nanotube surface and optical properties in a fully reversible fashion. Aspects of organic, physical and analytical chemistry, as well as colloidal sciences are covered in this outstanding work which brings us one step closer to exploiting this super-material to its full potential.
Nondestructive Assay of Nuclear Materials for Safeguards and Security
by William H. Geist Peter A. Santi Martyn T. SwinhoeThis open access book describes the nondestructive assay techniques that are used for the measurement of nuclear material (primarily uranium and plutonium) for nuclear material accountancy purposes. It is a substantial revision to the so-called PANDA manual that has been a standard reference since its publication in 1991. The book covers the origin and interactions of gamma rays and neutrons as they affect nuclear measurements and also describes the theory and practice of calorimetry. The book gives a description of many instruments based on these techniques that are applied in the field. Although the basic physics has not changed since PANDA was first published, the last thirty years have seen many advances in analysis methods, instrumentation, and applications. The basic descriptions of the origin and interactions of radiation have been updated and include newer references. There have been extensive revisions of the description of gamma detection methods, attenuation correction procedures, and analysis methods, including for the measurement of uranium enrichment and the determination of plutonium isotopic composition. Extensive revisions and additions have also been made to the description of neutron detectors and to the explanation of neutron coincidence techniques. The chapter on neutron multiplicity techniques is a new addition to this edition. The applications of gamma and neutron techniques have been completely overhauled to remove obsolete systems and to include many current applications. The values of, and references to, nuclear data have been updated. This updated edition is an essential reference for academic researchers and practitioners in the field. This is an open access book.
Nondestructive Biomarkers in Vertebrates
by Cristina Fossi Claudio LeonzioNondestructive Biomarkers in Vertebrates presents an innovative approach for hazard assessment in vertebrates based on nondestructive rather than destructive methods. The book reviews the state of the art and defines the development and validation procedure of this new strategy. Biological materials, such as blood samples, epithelial tissue, eggs, feathers, and feces that can be obtained without stress or damage to the animal are suggested. Certain traditional studies (blood esterases, blood chemistry, mixed function oxidases, porphyrins, DNA damage, and cytological changes) can be performed on these specimens, along with new tests requiring only very small samples. This approach is developed to benefit protected, threatened species whose existence cannot be further jeopardized by the use of destructive methods. This volume will be particularly useful to ecotoxicologists, wildlife protection personnel, environmental consultants, and conservationist organizations.

Nonequilibrium Dynamics of Collective Excitations in Quantum Materials (Springer Theses)
by Edoardo BaldiniThis book studies the dynamics of fundamental collective excitations in quantum materials, focusing on the use of state-of-the-art ultrafast broadband optical spectroscopy. Collective behaviour in solids lies at the origin of several cooperative phenomena that can lead to profound transformations, instabilities and phase transitions. Revealing the dynamics of collective excitations is a topic of pivotal importance in contemporary condensed matter physics, as it provides information on the strength and spatial distribution of interactions and correlation. The experimental framework explored in this book relies on setting a material out-of-equilibrium by an ultrashort laser pulse and monitoring the photo-induced changes in its optical properties over a broad spectral region in the visible or deep-ultraviolet. Collective excitations (e.g. plasmons, excitons, phonons…) emerge either in the frequency domain as spectral features across the probed range, or in the time domain as coherent modes triggered by the pump pulse. Mapping the temporal evolution of these collective excitations provides access to the hierarchy of low-energy phenomena occurring in the solid during its path towards thermodynamic equilibrium. This methodology is used to investigate a number of strongly interacting and correlated materials with an increasing degree of internal complexity beyond conventional band theory.
Nonequilibrium Gas Dynamics and Molecular Simulation
by Iain D. Boyd Thomas E. SchwartzentruberThis current and comprehensive book provides an updated treatment of molecular gas dynamics topics for aerospace engineers, or anyone researching high-temperature gas flows for hypersonic vehicles and propulsion systems. It demonstrates how the areas of quantum mechanics, kinetic theory, and statistical mechanics can combine in order to facilitate the study of nonequilibrium processes of internal energy relaxation and chemistry. All of these theoretical ideas are used to explain the direct simulation Monte Carlo (DSMC) method, a numerical technique based on molecular simulation. Because this text provides comprehensive coverage of the physical models available for use in the DSMC method, in addition to the equations and algorithms required to implement the DSMC numerical method, readers will learn to solve nonequilibrium flow problems and perform computer simulations, and obtain a more complete understanding of various physical modeling options for DSMC than is available in other texts.
