Functional Hybrid MaterialsAuthor:
Gomez-Romero, Clement SanchezPages:

PDFLanguage:
EnglishISBN10:
3527304843The book you have in your hands is the result of a thrilling struggle. A struggle to depict, in a bit more than a handful of chapters, the blooming and multifaceted world of hybrid materials with functional properties and applications. Hybrid organic-inorganic materials constitute indeed a remarkable and growing category within the world of Materials Science. A realm where engineering the combination of dissimilar components at the nanometric and molecular level leads both to new challenges and opportunities for the development of novel and improved materials. This is a field where the boundaries between molecular and extended materials blur out, a field where ceramics and polymers meet at the chemical dimension to yield new materials that go well beyond conventional composites, a domain in which nanocomposites push forward the frontier of discovery. In this exciting field, remarkable structural materials, halfway between glass and polymers have been developed. Yet, the hybrid approach also offers great opportunities for the development of functional materials, a fertile ground to harness the chemical, physical, electrochemical or biological activity of a myriad organic and inorganic components and put them to work in the materials of tomorrow.

PDFLanguage:
EnglishISBN10:
047066584XAll you need to know about deploying VoIP protocols in one comprehensive and highly practical reference - Now updated with coverage on SIP and the IMS infrastructureThis book provides a comprehensive and practical overview of the technology behind Internet Telephony (IP), providing essential information to Network Engineers, Designers, and Managers who need to understand the protocols. Furthermore, the author explores the issues involved in the migration of existing telephony infrastructure to an IP - based real time communication service. Assuming a working knowledge of IP and networking, it addresses the technical aspects of real-time applications over IP. Drawing on his extensive research and practical development experience in VoIP from its earliest stages, the author provides an accessible reference to all the relevant standards and cutting-edge techniques in a single resource.Key Features:* Updated with a chapter on SIP and the IMS infrastructure
* Covers ALL the major VoIP protocols – SIP, H323 and MGCP
* Includes a large section on practical deployment issues gleaned from the authors’ own experience
* Chapter on the rationale for IP telephony and description of the technical and business drivers for transitioning to all IP networksThis book will be a valuable guide for professional network engineers, designers and managers, decision makers and project managers overseeing VoIP implementations, market analysts, and consultants. Advanced undergraduate and graduate students undertaking data/voice/multimedia communications courses will also find this book of interest.Olivier Hersent founded NetCentrex, a leading provider of VoIP infrastructure for service providers, then became CTO of Comverse after the acquisition of NetCentrex. He now manages Actility, provider of IMS based M2M and smartgrid infrastructure and applications.

PDFLanguage:
EnglishISBN10:
3527410139Filling the gap for a book covering vibronic, nonadiabatic and diabatic couplings as well as radiationless processes in context, this monograph compiles classic and cutting-edge work from numerous researchers into one handy source.Alongside a description of radiationless processes in statistical large molecules and calculational methods for intramolecular distributions, the authors also investigate the nuclear coordinate dependence of matrix elements. Whole chapters are devoted to the mathematical description of the lifetime and decay of a prepared states as well as miscellaneous applications. The text is supplemented by a number of appendices for optimum usability.With its integration of the necessary mathematical rigor, this is primarily intended for graduate students in theoretical physics and chemistry, but is also indispensable reading for those working in molecular physics, physical chemistry and laser physics.

EnglishISBN10:
0470660856The term steroid has become virtually synonymous with drug abuse in sport to the majority of the public. However these steroids - androgens - actually comprise only a single relatively small class of biologically active steroids, and are overshadowed by a large collection of compounds, a sizeable number of which are commercial drugs that share the same structural carbon skeleton. The development of these drugs has led to a large body of organic often denoted as "Steroid ".Steroid At A Glance pres a concise overview of the main principles and reactions of steroid . Topics covered include:* history, isolation and structure determination of steroids
* steroid nomenclature and stereo
* natural sources of steroids
* synthesis and reactions of aromatic a-ring steroids, androstanes, and pregnanes
* steroids with a spirolactone at position 17
* steroids with hetrocyclic ring A
* compounds derived from cholesterolBased on the highly successful and student friendly "at a glance" approach, the information is presented in integrated, self contained double page spreads of text and illustrative material. Students of and pharmacy using Steroid at a Glance will find they have a resource with which they can quickly, concisely and confidently acquire, regularly review and revise the basic facts that underpin the properties, synthesis and reactions of this important class of natural products. It will also serve as a handy bench reference for postgraduates and professional chemists.

Mathematical Modeling of Complex Biological Systems: A Kinetic Theory ApproachAuthor:
Abdelghani Bellouquid, Marcello DelitalaPages:

PDFLanguage:
EnglishISBN10:
0817643958This book describes the evolution of several socio-biological systems using mathematical kinetic theory. Specifically, it deals with modeling and simulations of biological systems—comprised of large populations of interacting cells—whose dynamics follow the rules of mechanics as well as rules governed by their own ability to organize movement and biological functions. The authors propose a new biological model for the analysis of competition between cells of an aggressive host and cells of a corresponding immune system.Because the microscopic description of a biological system is far more complex than that of a physical system of inert matter, a higher level of analysis is needed to deal with such complexity. Mathematical models using kinetic theory may represent a way to deal with such complexity, allowing for an understanding of phenomena of nonequilibrium statistical mechanics not described by the traditional macroscopic approach. The proposed models are related to the generalized Boltzmann equation and describe the population dynamics of several interacting elements (kinetic population models).The particular models proposed by the authors are based on a framework related to a system of integro-differential equations, defining the evolution of the distribution function over the microscopic state of each element in a given system. Macroscopic information on the behavior of the system is obtained from suitable moments of the distribution function over the microscopic states of the elements involved. The book follows a classical research approach applied to modeling real systems, linking the observation of biological phenomena, collection of experimental data, modeling, and computational simulations to validate the proposed models. Qualitative analysis techniques are used to identify the prediction ability of specific models.The book will be a valuable resource for applied mathematicians as well as researchers in the field of biological sciences. It may be used for advanced graduate courses and seminars in biological systems modeling with applications to collective social behavior, immunology, and epidemiology.
