This book provides a comprehensive reference for everything that has to do with digital circuits. The author focuses equally on all levels of abstraction. He tells a bottom-up story from the physics level to the finished product level. The aim is to provide a full account of the experience of designing, fabricating, understanding, and testing a microchip. The content is structured to be very accessible and self-contained, allowing readers with diverse backgrounds to read as much or as little of the book as needed. Beyond a basic foundation of mathematics and physics, the book makes no assumptions about prior knowledge. This allows someone new to the field to read the book from the beginning. It also means that someone using the book as a reference will be able to answer their questions without referring to any external sources.
Topics in Current Aerosol Research deals with the fundamental aspects of aerosol science, with emphasis on experiment and theory describing highly dispersed aerosols (HDAs) as well as the dynamics of charged suspensions. Topics covered range from the basic properties of HDAs to their formation and methods of generation; sources of electric charges; interactions between fluid and aerosol particles; and one-dimensional motion of charged cloud of particles. This volume is comprised of 13 chapters and begins with an introduction to the basic properties of HDAs, followed by a discussion on the formation of condensation HDAs. Some of the methods of generation of HDAs are considered, including atomization, physical condensation of vapor, and chemical reactions in the gas phase are considered. A ""transport"" model for electrically charged aerosols is described. Subsequent chapters explore methods of investigation of HDAs in suspended state and based on particle precipitation; transfer processes in HDAs, including mass transfer, charge transfer, momentum transfer, and heat transfer; and charging of particulate matter by collection. This book will be a useful resource for practicing...
Ion channels are intimately involved in the everyday physiological functions that enable us to live a full and varied life. When disease strikes, malfunction of ion channels or their dependent is often involved, either as the cause or the effect of the illness. Thus, billions of dollars have been, and still are being, invested in research to understand the physiological and pathophysiological functions of ion channels in an attempt to develop novel therapeutic treatments for a wide range of diseases. This book provides a comprehensive overview of ion channel structure and function. It comprises two major parts. Part one is an introductory overview of the ion channel superfamily and the generic aspects of ion channel function. This part also reviews the methodologies by which ion channel function can be studied from the perspective of performing detailed biophysical characterization through to the deployment of high throughput approaches for identifying novel ion channel ligands. Part two of the book provides an in-depth review of the individual ion channel subfamilies and, as such, is subdivided into four broad sections: Voltage-Gated Ion Channels, Extracellular Ligand-Gated Ion...
Un thriller intenso y emotivo que corta la respiración y nos obliga a suponer y deducir página tras página hasta el final. Después de la caída es Dennis Lehane en su mejor versión, una nueva vuelta de tuerca de uno de los grandes escritores del noir norteamericano. Después de triunfar con la serie de los inolvidables detectives bostonianos Kenzie y Gennaro, de recibir el aplauso unánime por la tensión dramática y lírica de Mystic River y haberse consagrado con su trilogía histórica criminal de Joe Coughlin, Dennis Lehane nos sorprende con una trama de suspense psicológico. Rachel Childs superó una infancia difícil hasta convertirse en una intrépida periodista de éxito en busca permanente de la verdad. Sin embargo, cuando le toca cubrir la catástrofe humanitaria de Haití como enviada especial, Rachel sufre una crisis nerviosa en directo que acaba con la confianza en sí misma, con su carrera y con su matrimonio. En plena lucha contra la agorafobia y los ataques de pánico, conoce a Brian, un hombre especial que la entiende y la apoya. Su amor incondicional la ayuda a reponerse, hasta que un encuentro casual en una tarde lluviosa hace que su vida se tambalee de...

Holm oak (Quercus ilex L.) forests and woodlands have been considered as a paradigm for Mediterranean terrestrial ecosystems. In the western part of the Mediterranean Basin, these forests and woodlands occupy large areas and thus play a very important role in the landscape. A number of research projects from the Centre d'Ecologie Fonctionnelle et Evolutive (CEFE), the Centre de Recerca Ecológica i Aplicacions Forestals (CREAF), and from many other laboratories are currently focusing on Q. ilex ecosystems, and a number of problems have appeared concerning not only basic knowledge but also management aspects. For this reason, the CEFE and the CREAF decided to jointly organize the workshop on Quercus ilex L. Ecosystems, which was held in Montpellier and Barcelona in September 1990. The present volume consists of a selection of papers presented during the workshop and other papers contributed after the workshop. The papers are divided into five sections: Biogeography and History; Structure, Productivity and Dynamics; Water Relationships; Nutrient Cycling; and Management.

Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of ...
