This book examines Thomas Hardy's representations of the road and the ways the archaeological and historical record of roads inform his work. Through an analysis of the uneven and often competing road signs found within three of his major novels - The Return of the Native, Tess of the D'Urbervilles, and Jude the Obscure - and by mapping the road travels of his protagonists, this book argues that the road as represented by Hardy provides a palimpsest that critiques the Victorian construction of social and sexual identities. Balancing modern exigencies with mythic possibilities, Hardy's fictive roads exist as contested spaces that channel desire for middle-class assimilation even as they provide the means both to reinforce and to resist conformity to hegemonic authority.
This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization - at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors' proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.
A blend of theory and practical advice, Modern NMR Techniques for Synthetic Chemistry illustrates how NMR spectroscopy can be used to determine the abundance, size, shape, and function of organic molecules. It provides you with a description the NMR technique used (more pictorial than mathematical), indicating the most common pulse sequences, some practical information as appropriate, followed by illustrative examples. This format is followed for each chapter so you can skip the more theoretical details if the practical aspects are what interest you. Following a discussion of basic parameters, the book describes the utility of NMR in detecting and quantifying dynamic processes, with particular emphasis on the usefulness of saturation-transfer (STD) techniques. It details pulsed-field gradient approaches to diffusion measurement, diffusion models, and approaches to 'inorganic' nuclei detection, important as many synthetic pathways to new organics involve heavier elements. The text concludes with coverage of applications of NMR to the analysis of complex mixtures, natural products, carbohydrates, and nucleic acids-all areas of activity for researchers working at the chemistry-life sciences interface. The book's unique format provides some theoretical insight into the NMR technique used, indicating the most common pulse sequences. The book draws upon several NMR methods that are resurging or currently hot in the field and indicates the specific pulse sequence used by various spectrometer manufacturers for each technique. It examines the analysis of complex mixtures, a feature not found in most books on this topic.
For more than five decades, scientists and researchers have relied on the Advances in Chromatography series for the most up-to-date information on a wide range of developments in chromatographic methods and applications. For Volume 55, established, well-known chemists offer cutting-edge reviews of chromatographic methods to pay tribute to the late Eli Grushka, beloved series editor, who inspired and mentored many in the field of separation science. The clear presentation of topics and vivid illustrations for which this series has become known makes the material accessible and engaging to analytical, biochemical, organic, polymer, and pharmaceutical chemists at all levels of technical skill.
Many new methods directed to organic and inorganic syntheses of useful intermediates are being developed to specifically address green and sustainable chemistry principles. Highlighting the importance of green metrics, the Green Syntheses series focuses on how to reliably substantiate and validate the level of "greenness" of chemical processes, providing practical synthetic methodologies and metrics for a rigorous proof of "greenness." In Green Syntheses, Volume 1, the first book of its kind, the editors determine appropriate material efficiency green metrics and use them to compare syntheses provided by the chapter authors with those previously published. Presenting a new concept in green chemistry, this book demonstrates what future publications might look like if green principles are followed and also incorporate the important ethical aspect of supplying rigorous procedures in laboratory practice and evidence of greenness of a given synthesis protocol using metrics analysis. This inaugural volume initiates the much-needed transition from stating the 12 guiding principles on the philosophy of green chemistry to the actualization and verification of it. The book addresses primarily the issue of material efficiency metrics, which measure the amount of waste produced relative to desired product. In each contributed example, full experimental details are given showing all quantities of materials used in the procedure. Authors discuss the green merits of their protocols in conjunction with the results of a thorough metrics analysis, allowing for in-depth discussion of insights about synthesis strategy and performance characteristics of the new and prior cited plans.
This volume details protocols on mass spectrometry and associated techniques. Chapters guide readers through micro- and macronutrients analysis, mass spectrometry-related methodologies, direct insertion, matrix-assisted laser desorption ionization (MALDI), gas chromatography (uni- and bi-dimensional), liquid chromatography, plasma mass spectrometry (ICP-MS), and analyses in food samples. Authoritative and cutting-edge, Mass Spectrometry for Food Analysis aims to provide comprehensive and updated state-of-art methodologies and models for food analysis.
This thesis provides the first comprehensive theoretical overview of the electronic and optical properties of two dimensional (2D) Indium Selenide: atomically thin films of InSe ranging from monolayers to few layers in thickness. The thesis shows how the electronic propertes of 2D InSe vary significantly with film thickness, changing from a weakly indirect semiconductor for the monolayer to a direct gap material in the bulk form, with a strong band gap variation with film thickness predicted and recently observed in optical experiments. The proposed theory is based on a specially designed hybrid k.p tight-binding model approach (HkpTB), which uses an intralayer k.p Hamiltonian to describe the InSe monolayer, and tight-binding-like interlayer hopping. Electronic and optical absorption spectra are determined, and a detailed description of subbands of electrons in few-layer films and the influence of spin-orbit coupling is provided. The author shows that the principal optical excitations of InSe films with the thickness from 1 to 15 layers broadly cover the visible spectrum, with the possibility of extending optical functionality into the infrared and THz range using intersubband transitions.
Oxygen-Ozone therapy is a complementary approach less known than homeopathy and acupuncture because it has come of age only three decades ago. This book clarifies that, in the often nebulous field of natural medicine, the biological bases of ozone therapy are totally in line with classical biochemistry, physiological and pharmacological knowledge. Ozone is an oxidizing molecule, a sort of super active oxygen, which, by reacting with blood components generates a number of chemical messengers responsible for activating crucial biological functions such as oxygen delivery, immune activation, release of hormones and induction of antioxidant enzymes, which is an exceptional property for correcting the chronic oxidative stress present in atherosclerosis, diabetes and cancer. Moreover, by inducing nitric oxide synthase, ozone therapy may mobilize endogenous stem cells, which will promote regeneration of ischemic tissues. The description of these phenomena offers the first comprehensive picture for understanding how ozone works and why. When properly used as a real drug within therapeutic range, ozone therapy does not only does not procure adverse effects but yields a feeling of wellness. Half the book describes the value of ozone treatment in several diseases, particularly cutanious infection and vascular diseases where ozone really behaves as a "wonder drug." The book has been written for clinical researchers, physicians and ozone therapists, but also for the layman or the patient interested in this therapy.

All microbes, including bacteria, viruses, and fungi, can be classified and identified by matching a few peptides known to be unique to each organism. Identifying Microbes by Mass Spectrometry Proteomics describes ways to identify microorganisms using powerful new techniques combining hardware and software and yielding highly accurate methods for detection, identification, and classification of microbes. This straightforward technology can be used to detect unknown and unsequenced microorganisms as well as microbes in complex environmental samples. This book reviews various mass analyzers used for detection and describes ionization methods frequently used for analysis of microbial constituents, a necessary step in the preparation of mass spectrometry (MS) samples. The text also discusses diverse processing methods, which are used to analyze MS files for matching mass spectral profiles, and examines protein and nucleic acid sequence-based methods capable of classification and identification of microbial agents. The book also covers sample collection methods and specific sample preparation techniques. The text addresses using computer software and bioinformatics approaches for data mining to discriminate microbes using mass spectrometry proteomics (MSP). It also discusses historical pattern recognition-based methods and other approaches such as analysis of pyrolysis products, chemical ionization (CI) of fatty acid methyl esters, and MALDI-MS. The text contains examples of the application of the MSP technique for microbe detection and includes a survey of suitable and commercially available MS-based platforms. Successful applications include the identification of unknown microbes in honey bees associated with colony collapse disorder and the analysis of virus strains from the 2009 influenza pandemic. The final chapter outlines future trends in these groundbreaking uses of MS techniques, which are fast, not limited by sample type, and show potential in answering complex environmental questions.
