Asphaltenes and Asphalts, 2
Part B
1st Edition
Volume 40B
T.F. Yen + 1 more
English
This is the second volume in the series of Asphaltenes and Asphalts. Since the publication of the first volume in 1994, there has been a significant advancement in our knowledge. Knowledge of both asphaltenes and asphalts is needed by several disciplines, and often the progress is dictated by interdisciplinary sciences and technology. This includes material sciences, fuel sciences, chemical engineering, civil engineering, environmental engineering, polymer sciences, transportation engineering, petroleum engineering, chemistry, geological sciences, physics, geochemistry rheology, biological sciences, tribology, soil sciences, petroleum science. The development in this field is not based on our knowledge of chemistry or petroleum engineering alone, as many chemists and petroleum engineers believe. In this volume, therefore, significant contributions from different disciplines have been included.
Non-Linear Mass Transfer and Hydrodynamic Stability
1st Edition
C.B. Boyadjiev + 1 more
English
Surveyed in this book are the kinetics of non-linear mass transfer and its effects on hydrodynamic stability in systems with intensive interphase mass transfer, in electrochemical systems with high current density and in chemically reacting systems.In Part 1 the non-linear mass transfer as a result of an intensive interphase mass transfer in the gas (liquid)-solid surface, gas-liquid and liquid-liquid systems is considered in the duffusion boundary layer approximation as well as in flat channel taking the longitudinal diffusion into account. The influence of the direction of the intensive interphase mass transfer on heat transfer and multi-component mass transfer is illustrated.Part 2 discusses non-linear mass transfer in electrochemical systems with high current density using the examples of the anode dissolving of metals in the electrolyte flow and the electro-separation of metals out of concentrated solutions. The theory of the measured electrochemical treatment of metals and alloys, which is a method of wide practical use, has been elaborated on this basis.In Part 3 the non-linear mass transfer in chemically reacting systems is considered in the cases of: non-linearity of the equations of the chemical reaction's kinetics and intensive interphase mass transfer or thermo-capillary effect due to chemical reactions. On this basis, the mechanisms and the macro-kinetics of the chemical transformations in the gas-liquid systems are discussed.Part 4 is dedicated to the chemical reaction kinetics in stationary two phase systems at an arbitrary contact time between phases.In Part 5 the effects of concentration gradients are considered in the approximations of the linear theory of the hydrodynamic stability of almost parallel flows.In systems with intensive interphase mass transfer, the Marangoni effect could also be observed, beside the effect of non-linear mass transfer. A comparative analysis of both effects is made in this book.
Power Geometry in Algebraic and Differential Equations
1st Edition
Volume 57
A.D. Bruno
English
The geometry of power exponents includes the Newton polyhedron, normal cones of its faces, power and logarithmic transformations. On the basis of the geometry universal algorithms for simplifications of systems of nonlinear equations (algebraic, ordinary differential and partial differential) were developed.The algorithms form a new calculus which allows to make local and asymptotical analysis of solutions to those systems.The efficiency of the calculus is demonstrated with regard to several complicated problems from Robotics, Celestial Mechanics, Hydrodynamics and Thermodynamics. The calculus also gives classical results obtained earlier intuitively and is an alternative to Algebraic Geometry, Differential Algebra, Lie group Analysis and Nonstandard Analysis.
Environmental Stressors and Gene Responses
1st Edition
Volume 1
J.M. Storey + 1 more
English
Cell and Molecular Responses to Stress is a new multi-volume book series from Elsevier Science that focuses on how organisms respond at a molecular level to environmental stresses imposed upon them. All organisms deal with variations in multiple environmental factors including temperature, oxygen, salinity, and water availability. Many show amazing tolerances to extreme stress with remarkable biochemical adaptations that allow life to persist under very difficult circumstances. This series explores the molecular mechanisms by which cells and organisms respond to stress, focusing on the variations in metabolic response that allow some cells and organisms to deal with extreme stress, others to endure stress within strict limits, and others to have a very low tolerance for changes in environmental parameters.Articles from within the series highlight the elastic limits of molecular responses in Nature, with examples drawn from animal, plant and bacteria systems.Volume 1, begins by considering some of the roles of environmental stress in determining the geographic distribution of animals and in promoting species divergence and then explores gene expression and metabolic responses to environmental stress with examples of adaptation to high and low temperature, osmotic, anoxia/ischemia, desiccation, high pressure and heavy metal stresses.
Wave Mechanics for Ocean Engineering
1st Edition
Volume 64
Paolo Boccotti
English
In a unitary way, this monograph deals with a wide range of subjects related to the mechanics of sea waves. The book highlights recent theoretical results on the dynamics of random wind-generated waves, on long-term wave statistics, and on beach planform evolution. A fresh approach is given to more traditional concepts. For example, new evidence from a recent series of small-scale field experiments is used to introduce some crucial topics like wave forces. Also, the book gives some worked examples for the design of offshore or coastal structures. An exciting subject dealt with in the book is the quasi-deterministic mechanics of three-dimensional wave groups in sea storms, and the loads exerted by these wave groups on offshore structures.The text is intended for researchers and graduate students in ocean engineering, but may also be understood by undergraduates. The more complex concepts are explained with examples or more extensive case studies.
Multi-Level Methods in Lubrication
1st Edition
Volume 37
C.H. Venner + 1 more
English
Efficient numerical solution of realistic and, therefore, complex equation systems occupies many researchers in many disciplines. For various reasons, but mainly in order to approximate reality, a very large number of unknowns are needed. Using classical techniques, the solution of such a system of equations would take too long, and so sometimes MultiLevel techniques are used to accelerate convergence. Over the last one and a half decades, the authors have studied the problem of Elastohydrodynamic Lubrication, governed by a complex integro-differential equation. Their work has resulted in a very efficient and stable solver. In this book they describe the different intermediate problems analyzed and solved, and how those ingredients finally come together in the EHL solver. A number of these intermediate problems, such as Hydrodynamic Lubrication and Dry Contact, are useful in their own right. In the Appendix the full codes of the Poisson problem, the Hydrodynamic Lubrication problem, the dry contact solver and the EHL solver are given. These codes are all written in 'C' language, based on the 'ANSI-C' version.
Cerebellar Modules: Molecules, Morphology, and Function
1st Edition
Volume 124
N.M. Gerrits + 2 more
English
The present volume of Progress in Brain Research contains the proceedings of a Symposium entitled Cerebellar Modules: Molecules, Morphology and Function, which was held to mark the retirement of Jan Voogd as chairman of the Department of Anatomy at the Erasmus University of Rotterdam. The contributions of leading cerebellar scientists representing a variety of disciplines focussed around the issue of the cerebellar modular compartmentalization... the intriguing composition of which has for many decades been the driving force behind Voogd's extraordinarily detailed anatomical analyses.The first section of the book, Development, concentrates on the genetic basis of different aspects of compartmentalized development including a most important contribution on the postnatal development of the climbing fiber system. Gene expression is also an important element in the next section, Interneurons, which provides striking new data and hypotheses on the functional anatomy of granule cells, Golgi cells and unipolar brush cells. Particularly interesting are several contributions that offer a novel view on parallel fiber function. The section Modules and Circuits provides a number of state-of-the-art analyses using electrophysiological... and classical and transneuronal virus tracing techniques. The emphasis lies on the olivocerebellar circuits and the oculomotor system The final section, Models and Learning, offers an insight into the progress on the mechanisms and network organization of adaptation and learning, not only in classical paradigms like oculomotor and eye blink responses but also in studies linking gene expression to behavioral paradigmsThe editors are confident that the exciting data and concepts collected in this volume will strengthen the multidisciplinary approach in the field of cerebellar research.
Controlled Release Veterinary Drug Delivery
Biological and Pharmaceutical Considerations
1st Edition
Michael J. Rathbone + 1 more
English
Many controlled release veterinary drug delivery systems (CRVDDS) are presently in use, and recently there has been a host of new CRVDDS within veterinary medicine. The challenges of this area of drug delivery arise from the unique anatomy and physiology of the target animal, the cost constraints associated with the value of the animal being treated and the extended periods of time that delivery must be sustained for (often measured in months).The purpose of this book is to introduce the reader to the unique opportunities and challenges of the field of CRVDDS and to explain and discuss the basic controlled release principles underlying the development of CRVDDS. Its aim is to provide an overview of many of the areas where CRVVDS have application, and to highlight the opportunities and prospects for controlled release technology in the veterinary field.Controlled Release Veterinary Drug Delivery comprises chapters that provide workers in the field (and those interested in this area) with information on the design, development and assessment of a variety of CRVDDS. The book contains chapters that describe the relevant animal physiological and anatomical considerations alongside descriptions of current and emerging controlled release delivery systems for a variety of routes for drug delivery, and present overviews on the physical and chemical assessment of veterinary controlled release delivery systems.The veterinary area is abound with opportunities for the development of controlled release drug delivery technologies. It is an area of medicine that is open to the acceptance of novel drug delivery devices, and which readily encompasses the use of novel routes of administration. It is an area of many unmet needs, most of which offer opportunities and unique challenges for the innovative formulation scientist to provide solutions. This book will provide an insight into the biological, clinical and pharmaceutical challenges that face the formulation scientist in this interesting and diverse area of research.
