Electromagnetic Properties of Multiphase Dielectrics

Electromagnetic Properties of Multiphase Dielectrics



Recently, several applications, primarily driven by microtechnology, have emerged where the use of materials with tailored electromagnetic (dielectric) properties are necessary for a successful overall design. The “tailored” aggregate properties are achieved by combining an easily moldable base matrix with particles having dielectric properties that are chosen to deliver (desired) effective properties. In many cases, the analysis of such materials requires the simulation of the macroscopic and microscopic electromagnetic response, as well as its resulting coupled thermal response, which can be important to determine possible failures in “hot spots.” This necessitates a stress analysis. Furthermore, because, oftentimes, such processes initiate degratory chemical processes, it can be necessary to also include models for these processes as well. A central objective of this work is to provide basic models and numerical solution strategies to analyze the coupled response of such materials by direct simulation using standard laptop/desktop equipment. Accordingly, this monograph covers: (1) The foundations of Maxwell’s equations, (2) Basic homogenization theory,(3) Coupled systems (electromagnetic, thermal, mechanical and chemical),(4) Numerical methods and(5) An introduction to select biological problems.The text can be viewed as a research monograph suitable for use in an upper-division undergraduate or first year graduate course geared towards students in the applied sciences, mechanics and mathematics that have an interest in the analysis of particulate materials.

General, Organic and Biological Chemistry

General, Organic and Biological Chemistry



This General, Organic and Biochemistry text has been written for students preparing for careers in health-related fields such as nursing, dental hygiene, nutrition, medical technology and occupational therapy. It is also suited for students majoring in other fields where it is important to have an understanding of the basics of chemistry. Students need have no previous background in chemistry, but should possess basic math skills. Raymond was crafted to take advantage of recent trends in the GOB market. It is a shorter, lighter book with a new, integrated table of contents that develops general, organic, and biochemistry topics together, rather than in isolation. In introducing GOB material, this text uses an integrated approach in which related general chemistry, organic chemistry, and biochemistry topics are presented in adjacent chapters. This approach helps students see the strong connections that exist between these three branches of chemistry, and allows instructors to discuss these, interrelationships while the material is still fresh in students’ minds. Having a shorter time interval between when a topic is first presented and when it is reintroduced can help students assimilate the material more readily.

Mathematical Biophysics

Mathematical Biophysics



This book presents concise descriptions and analysis of the classical and modern models used in mathematical biophysics. The authors ask the question ‘what new information can be provided by the models that cannot be obtained directly from experimental data?’ Actively developing fields such as regulatory mechanisms in cells and subcellular systems and electron transport and energy transport in membranes are addressed together with more classical topics such as metabolic processes, nerve conduction and heart activity, chemical kinetics, population dynamics, and photosynthesis. The main approach is to describe biological processes using different mathematical approaches necessary to reveal characteristic features and properties of simulated systems. With the emergence of powerful mathematics software packages such as MAPLE, Mathematica, Mathcad, and MatLab, these methodologies are now accessible to a wide audience.

Visualization of Hydrogen-Bond Dynamics

Visualization of Hydrogen-Bond Dynamics



The hydrogen bond represents an important interaction between molecules, and the dynamics of hydrogen bonds in water create an ever-present question associated with the process of chemical and biological reactions. In spite of numerous studies, the process remains poorly understood at the microscopic level because hydrogen-bond dynamics, such as bond rearrangements and hydrogen/proton transfer reactions, are extremely difficult to probe. Those studies have been carried out by means of spectroscopic methods where the signal stems from the ensemble of a system and the hydrogen-bond dynamics were inferred indirectly. This book addresses the direct imaging of hydrogen-bond dynamics within water-based model systems assembled on a metal surface, using a scanning tunneling microscope (STM). The dynamics of individual hydrogen bonds in water clusters, hydroxyl clusters, and water-hydroxyl complexes are investigated in conjunction with density functional theory. In these model systems, quantum dynamics of hydrogen bonds, such as tunneling and zero-point nuclear motion, are observed in real space. Most notably, hydrogen atom relay reactions, which are frequently invoked across many fields of chemistry, are visualized and controlled by STM. This work presents a means of studying hydrogen-bond dynamics at the single-molecule level, providing an important contribution to wide fields beyond surface chemistry.

Chaos

Chaos



This eleventh volume in the Poincar Seminar Series presents an interdisciplinary perspective on the concept of Time, which poses some of the most challenging questions in science. Five articles, written by the Fields medalist C. Villani, the two outstanding theoretical physicists T. Damour and C. Jarzynski, the leading experimentalist C. Salomon, and the famous philosopher of science H. Price, describe recent developments related to the mathematical, physical, experimental, and philosophical facets of this fascinating concept. These articles are also highly pedagogical, as befits their origin in lectures to a broad scientific audience. Highlights include a description of the manifold fundamental physical issues in play with time, in particular with the changes of perspective implied by Special and General Relativity; a mathematically precise discussion of irreversibility and entropy in the context of Boltzmann’s and Vlasov’s equations; a thorough survey of the recently developed thermodynamics at the nanoscale, the scale most relevant to biological physics; a description of the new cold atom space clock PHARAO to be installed in 2015 onboard the International Space Station, which will allow a test of Einstein’s gravitational shift with a record precision of 2 10-6, and enable a test of the stability over time of the fundamental constants of physics, an issue first raised by Dirac in 1937; and last, but not least, a logical and clarifying philosophical discussion of Time’s arrow, a phrase first coined by Eddington in 1928 in a challenge to physics to resolve the puzzle of the time-asymmetry of our universe, and echoed here in a short pome en prose by C. de Mitry. This book should be of broad general interest to physicists, mathematicians, and philosophers.

Development and Engineering of Dopamine Neurons

Development and Engineering of Dopamine Neurons



The neurotransmitter dopamine has just celebrated its 50th birthday. The discovery of dopamine as a neuronal entity in the late 1950s and the notion that it serves in neurotransmission has been a milestone in the field of neuroscience research. This milestone marked the beginning of an era that explored the brain as an integrated collection of neuronal systems that one could distinguish on basis of neurotransmitter identities, and importantly, in which one started to be able to pinpoint the seat of brain disease. The mesodiencephalic dopaminergic (mdDA) system, previously designated as midbrain dopaminergic system, has received much attention since its discovery. The initial identification of dopamine as a neurotransmitter in the central nervous system (CNS) and its relevance to psychiatric and neurological disorders have stimulated a plethora of neurochemical, pharmacological and genetic studies into the function of dopamine neurons and their projections. In the last decade, studies on gene expression and development have further increased the knowledge of this neuronal population and have unmasked a new level of complexity. The start of the molecular dissection of the mdDA system has been marked by the cloning and characterization of Nurr1 and Pitx3. These transcription factors were shown to have a critical function during mdDA development. These initial studies have been followed by the identification of many other proteins that have a crucial function in the creation of a dopamine neuron permissive region, induction of precursors, induction of terminal differentiation and finally maintenance of the mdDA neuronal pool. In addition, work showing that the historically distinguished regions of the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA ) harbor molecularly distinct sets of neuronal groups with specific connectivity patterns has added a new layer ofcomplexity to how mdDA neurons are generated and function in the adult CNS. The current challenge in the field of dopamine research is to characterize the full extent of molecular processes that underlie mdDA neuron programming and to translate these findings into viable approaches for embryonic stem (ES)-cell engineering as an ultimate treatment of degenerative diseases as Parkinsons disease. The chapters presented in this book provide an overview of the different stages that are distinguished during mdDA neuronal development. Chapter 1 discusses the dopamine systems of the zebrafish, being a powerful model organism for genetic intervention on the developmental programming of neuronal systems. In Chapter 2 an overview is presented of dopamine systems that are present in the vertebrate CNS. Chapters 3-6 discuss the early specification of dopamine precursors and the programs that lead to terminal differentiation. In Chapters 7 and 8 the maintenance of dopamine neurons is discussed with a special emphasis on neurotrophic support. The specific connectivity of the dopamine system and the axon guidance rules that apply to developing dopamine neurons are described in Chapter 9. An overview of ES-cell engineering of dopamine neurons is presented in Chapters 10 and 11. The research directed towards unraveling the molecular programming of mdDA neurons continues to be highly exciting. One may expect that novel biological principles will continue to emerge from this population of neurons. In the near future the field as a whole will mature towards a more comprehensive understanding of mdDA neuronal development and network integration, and will continue to apply knowledge of dopamine neuron development and function to the treatment of human disease.

Rhythmanalysis

Rhythmanalysis



Rhythmanalysis displays all the characteristics which made Lefebvre one of the most important Marxist thinkers of the twentieth century. In the analysis of rhythms — both biological and social — Lefebvre shows the interrelation of space and time in the understanding of everyday life.With dazzling skills, Lefebvre moves between discussions of music, the commodity, measurement, the media and the city. In doing so he shows how a non-linear conception of time and history balanced his famous rethinking of the question of space. This volume also includes his earlier essays on ‘The Rhythmanaly.
