Heavily-Doped 2D-Quantized Structures and the Einstein Relation
by Sitangshu Bhattacharya Kamakhya P. GhatakThis book presents the Einstein Relation(ER) in two-dimensional (2-D) Heavily Doped (HD) Quantized Structures. The materials considered are quantized structures of HD non-linear optical, III-V, II-VI, Ge, Te, Platinum Antimonide, stressed materials, GaP, Gallium Antimonide, II-V, Bismuth Telluride together with various types of HD superlattices and their Quantized counterparts respectively. The ER in HD opto-electronic materials and their nanostructures is studied in the presence of strong light waves and intense electric fields on the basis of newly formulated electron dispersion laws that control the studies of such quantum effect devices. The suggestion for the experimental determination of HD 2D and 3D ERs and the importance of measurement of band gap in HD optoelectronic materials under intense built-in electric field in nanodevices and strong external photo excitation (for measuring photon induced physical properties) are also discussed in this context. The influence of crossed electric and quantizing magnetic fields on the ER of the different 2D HD quantized structures (quantum wells, inversion and accumulation layers, quantum well HD superlattices and nipi structures) under different physical conditions is discussed in detail. This monograph contains 100 open research problems which form the integral part of the text and are useful for both Ph. D aspirants and researchers in the fields of condensed matter physics, solid-state sciences, materials science, nano-science and technology and allied fields.

Heavy Metal Remediation: Sustainable Nexus Approach (Earth and Environmental Sciences Library)
by Nitish KumarHeavy metals, in general trace elements, are one of the major environmental problems. Nowadays, increasing environmental and global public health concerns related with environmental contamination by heavy metals are well known. Moreover, human exposure has risen dramatically because of an exponential increase of their use in several activities such as agricultural, industrial, technological and urban applications. They are presented in soils, water and atmosphere and they are a serious risk for the food chain.Approximately 10 million contaminated sites have been reported globally, occupying approximately 49.42 million acres of land, of which >50% is contaminated with toxic heavy metals. This situation warrants immediate attention to limit the introduction of heavy metals into soil systems and to remove the prevailing heavy metals from polluted soils. However, the majorities of existing heavy-metal-removal technologies are expensive, inefficient, or generate secondary pollutants. Therefore, it is of great importance to develop cheaper, environmentally friendly and sustainable approaches (including the development of new immobilizing agents) to manage and rehabilitate heavy-metal-contaminated soils. In the light of the aforementioned facts, this book sheds light on this global environmental issue, and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. It addresses sustainable heavy metal contamination remediation strategies using the potential applications of recent biological technology such as biotechnology, bioremediation, phytoremediation, biochar, absorbent, genetic engineering, and nanotechnology approaches. This book is of interest to researchers, teachers, environmental scientists, environmental engineers, environmentalists, and policy makers. Also, the book serves as additional reading material for undergraduate and graduate students of environmental microbiology, biotechnology, eco-toxicology, environmental remediation, waste management, and environmental sciences as well as the general audience.

Heavy Metal Toxicity: Environmental Concerns, Remediation and Opportunities
by Rajeev Pratap Singh Pooja Singh Amrita SrivastavaThis contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.
Heavy Metal Toxicity: Human Health Impact and Mitigation Strategies (Environmental Science and Engineering)
by Nitish KumarThis edited book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by heavy metals contamination of soil and plants. In recent years, contamination of the environment by heavy metals has become a major concern. Their multiple industrial, domestic, agricultural, medical, and technological applications have led to their wide distribution in the environment, raising concerns over their potential effects on human health and the environment. Owing to their toxic, non-degradable, and bio-accumulative nature, the health burden on the population has increased significantly. Heavy metals such as arsenic, lead, mercury, cadmium, and uranium do not play a significant role in metabolism in the human body and are thus toxic. Their exposure in high concentration can cause acute toxicity resulting in acute health conditions, which is easy to observe and regulate, while similar is not visible for immediate action when their exposure is in trace amounts over the years. Heavy metals enter in the food chain through consumption of plant material. A high concentration of heavy metals has been found to be harmful to vegetation. As the heavy metals concentration in plants increases, it adversely affects several biological parameters and eventually renders the soil barren.The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. This book is a valuable resource to students, academicians, researchers, and environmental professionals who are doing field work on heavy metals contamination throughout the world.

Heavy Metal and You
by Christopher KrovatinSam wears spiked bracelets, gets wasted with his friends, and has almost encyclopedic knowledge about heavy-metal music. But he's also incredibly intelligent and as knowledgeable about classic literature as he is about the music he loves. Sam attends an expensive all-boys prep school in New York City, and he and his buddies often cut classes to smoke or get an early start on the weekend. But all good things must end, and they do with a sudden crash when Sam begins to date Melissa, a straightedge who doesn't drink or do drugs and doesn't like the fact that he does. Sam tries to modify his behavior for the girl who is more important to him than he ever thought possible, but pleasing Melissa means completely changing who he is. This romance is chock-full of music references, slang, and general metalhead band knowledge such as album release dates, etc. The language is raw and full of sexual talk and innuendo, especially among Sam and his friends. The main characters are well developed and mostly believable, if a bit more emotional than expected on Sam's part. The plot moves quickly and jumps from past to present, with Sam interspersing his current situation with relevant scenes from his past. This rapid progression, as well as the realistic situations and language, keep teens' attention, making the book a good choice for reluctant readers.

Heavy Metals in the Marine Environment
by Robert W. FurnessThe aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.
Heavy Neutral Particle Decays to Tau Pairs
by Michail BachtisThe work presented in this thesis spans a wide range of experimental particle physics subjects, starting from level-1 trigger electronics to the final results of the search for Higgs boson decay and to tau lepton pairs. The thesis describes an innovative reconstruction algorithm for tau decays and details how it was instrumental in providing a measurement of Z decay to tau lepton pairs. The reliability of the analysis is fully established by this measurement before the Higgs boson decay to tau lepton pairs is considered. The work described here continues to serve as a model for analysing CMS Higgs to tau leptons measurements.
Heavy Quarkonium Production Phenomenology and Automation of One-Loop Scattering Amplitude Computations
by Hua-Sheng ShaoThis book focuses on the study of heavy quarkonium production at high-energy colliders as a useful tool to explain both the perturbative and non-perturbative aspects of quantum choromodynamics. It provides the first comprehensive comparison between the theory and recent experiments and clarifies some longstanding puzzles in the heavy quarkonium production mechanism. In addition, it describes in detail a new framework for implementing precise computations of the physical observables in quantum field theories based on recently developed techniques. It can be used to simulate the complicated collider environment of the Large Hadron Collider at the Conseil Européen pour la Recherche Nucléaire (CERN). Its accomplishment implies that the Monte Carlo simulations for high-energy physics experiments have reached the limits of precision. It offers readers a wealth of valuable information on the relevant techniques.
Heavy WIMP Effective Theory
by Mikhail P. SolonThis book is about dark matter's particle nature and the implications of a new symmetry that appears when a hypothetical dark matter particle is heavy compared to known elementary particles. Dark matter exists and composes about 85% of the matter in the universe, but it cannot be explained in terms of the known elementary particles. Discovering dark matter's particle nature is one of the most pressing open problems in particle physics. This thesis derives the implications of a new symmetry that appears when the hypothetical dark matter particle is heavy compared to the known elementary particles, a situation which is well motivated by the null results of searches at the LHC and elsewhere. The new symmetry predicts a universal interaction between dark matter and ordinary matter, which in turn may be used to determine the event rate and detectable energy in dark matter direct detection experiments. The computation of heavy wino and higgsino dark matter presented in this work has become a benchmark for the field of direct detection. This thesis has also spawned a new field of investigation in dark matter indirect detection, determining heavy WIMP annihilation rates using effective field theory methods. It describes a new formalism for implementing Lorentz invariance constraints in nonrelativistic theories, with a surprising result at 1/M^4 order that contradicts the prevailing ansatz in the past 20 years of heavy quark literature. The author has also derived new perturbative QCD results to provide the definitive analysis of key Standard Model observables such as heavy quark scalar matrix elements of the nucleon. This is an influential thesis, with impacts in dark matter phenomenology, field theory formalism and precision hadronic physics.
Heavy Water and the Wartime Race for Nuclear Energy
by Per F DahlHeavy water (deuterium oxide) played a sinister role in the race for nuclear energy during the World War II. It was a key factor in Germany's bid to harness atomic energy primarily as a source of electric power; its acute shortage was a factor in Japan's decision not to pursue seriously nuclear weaponry; its very existence was a nagging thorn in the side of the Allied powers. Books and films have dwelt on the Allies' efforts to deny the Germans heavy water by military means; however, a history of heavy water has yet to be written.Filling this gap, Heavy Water and the Wartime Race for Nuclear Energy concentrates on the circumstances whereby Norway became the preeminent producer of heavy water and on the scientific role the rare isotope of hydrogen played in the wartime efforts by the Axis and Allied powers alike. Instead of a purely technical treatise on heavy water, the book describes the social history of the subject.The book covers the discovery and early uses of deuterium before World War II and its large-scale production by Norsk Hydro in Norway, especially under German control. It also discusses the French-German race for the Norwegian heavy-water stocks in 1940 and heavy water's importance for the subsequent German uranium project, including the Allied sabotage and bombing of the Norwegian plants, as well as its lesser role in Allied projects, especially in the United States and Canada. The book concludes with an overall assessment of the importance and the perceived importance of heavy water for the German program, which alone staked everything on heavy water in its quest for a nuclear chain reaction.
