Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This collection presents research evidence and company examples developed over the past decade showing how to create organizations that add value to investors, customers and employees. It first illustrates why and how human resource management practices become a competitive advantage. These practices are also reviewed in an international context, an increasingly important reality as business become more global. 326 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The explosive growth in computational power over the past several decades offers new tools and opportunities for economists. This handbook volume surveys recent research on Agent-based Computational Economics (ACE), the computational study of economic processes modeled as dynamic systems of interacting agents. Empirical referents for 'agents' in ACE models can range from individuals or social groups with learning capabilities to physical world features with no cognitive function. Topics covered include: learning; empirical validation; network economics; social dynamics; financial markets; innovation and technological change; organizations; market design; automated markets and trading agents; political economy; social-ecological systems; computational laboratory development; and general methodological issues. 904 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Tissue engineering is an emerging interdisciplinary field, occupying a major position in the regenerative medicine that aims at restoring lost or damaged tissues and organs with use of cells. Regenerative medicine includes cellular therapy and tissue engineering. In general, the former treats patients by cell infusion alone, while tissue engineering needs biomaterials and growth factors in addition to cells. Biomaterials function in tissue engineering as the scaffold or template for cells to proliferate, differentiate, and produce matrices. Tissue Engineering focuses on the fundamentals (biomaterials, scaffolds, cell cultures, bioreactors, animal models etc.), recent animal and human trials, and future prospects regarding tissue engineering. Almost twenty years have passed since the advent of the tissue engineering, whicht uses cells, scaffolds, and growth factors for regeneration of neotissues. The number of investigations on tissue engineering is still increasing tremendously. Nevertheless, it seems likely that the number of reports describing clinical trials of tissue engineering will remain very limited. Even the studies that apply tissue engineering research to large animals have not been performed yet on a large scale. The major objective of this book is to address this question from a science and technology point of view, and to describe the principles of basic technologies that have currently been developed by numerous research groups. 490 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -VESUVIUS 2000 is an interdisciplinary project aimed at producing a safe and prosperous habitat for the people living around Vesuvius. To produce this environment requires an effective collaboration between the experts and the public, whereby the danger from the volcano is used to reorganize the territory and thus produce new opportunities for the people surrounding the volcano. As an all inclusive physico-mathematical-computer model of the volcano, the Global Volcanic Simulator is a key tool for determining the effects of different eruption scenarios and thus for urban planning of the territory. Unlike the evacuation plans which tend to manage emergencies, VESUVIUS 2000 aims at preparing the Vesuvius area to confront future eruptions with minimal socio-economic and cultural consequences. 432 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the aims of this book was to focus the attention of specialists to the diversity of the effects of the ionising radiation on biological and physical systems. Special emphasis has been placed on the exquisite complexities/differences introduced by high ionisation density versus low ionisation density irradiation in both biological and physical systems (Scholz - Chapter 1, Horowitz - Chapter 2, Olko - Chapter 3). As well we wanted to point out the need for novel experimental and theoretical approaches required to advance the important fields of micro and nanodosimetry. Important first steps have already been taken, for example, the accelerated application of semiconductor detectors in their various forms to microdosimetry and as well to practical, important applications in the radiation dosimetry of oncological procedures (Rosenfeld - Chapter 6). The vast number of applications of TLD to radiation dosimetry are not neglected; a special chapter is devoted to the application of TLDs to medical dosimetry applications (Mobit and Kron - Chapter 7) as well as a tutorial approach in an additional chapter to the cavity theories required to extrapolate dose from the detector medium to the tissue medium (Mobit and Sandison - Chapter 5). One of the major features of this book is the intensive, in depth, coverage of the theory and modelling of TL both from the solid state physics point of view (Chen - Chapter 4) and the microdosimetic point of view (Horowitz - Chapter 2 and Olko - Chapter 3). The many puzzling, quaint, quizzical features of TL science can now be understood in the framework of these advanced theoretical models, explained in straightforward, understandable terms. 500 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many large mathematical models, not only models arising and used in environmental studies, are described by systems of partial differential equations. The discretization of the spatial derivatives in such models leads to the solution of very large systems of ordinary differential equations. These systems contain many millions of equations and have to be handled over large time intervals by applying many time-steps (up to several hundred thousand time-steps). Furthermore, many scenarios are as a rule to be run. This explains the fact that the computational tasks in this situation are enormous. Therefore, it is necessary to select fast numerical methods; to develop parallel codes and, what is most important when the problems solved are very large to organize the computational process in a proper way.The last item (which is very often underestimated but, let us re-iterate, which is very important) is the major topic of this book. In fact, the proper organization of the computational process can be viewed as a preparation of templates which can be used with different numerical methods and different parallel devices. The development of such templates is described in the book. It is also demonstrated that many comprehensive environmental studies can successfully be carried out when the computations are correctly organized. Thus, this book will help the reader to understand better that, while (a) it is very important to select fast numerical methods as well as (b) it is very important to develop parallel codes, this will not be sufficient when the problems solved are really very large. In the latter case, it is also crucial to exploit better the computer architecture by organizing properly the computational process. 392 pp. Englisch.
