Ernst Equation and Riemann Surfaces : Analytical and Numerical Methods
Exact solutions to Einstein`s equations have been useful for the understanding of general relativity in many respects. They have led to physical concepts as black holes and event horizons and helped to visualize interesting features of the theory. In addition they have been used to test the quality of various approximation methods and numerical codes. The most powerful solution generation methods are due to the theory of Integrable Systems. In the case of axisymmetric stationary spacetimes the Einstein equations are equivalent to the completely integrable Ernst equation. In this volume the solutions to the Ernst equation associated to Riemann surfaces are studied in detail and physical and mathematical aspects of this class are discussed both analytically and numerically.

Equilibrium statistical physics : Phases of matter and phase transitions
This is a textbook which gradually introduces the student to the statistical mechanical study of the different phases of matter and to the phase transitions between them. Throughout, only simple models of both ordinary and soft matter are used but these are studied in full detail. The subject is developed in a pedagogical manner, starting from the basics, going from the simple ideal systems to the interacting systems, and ending with the more modern topics. The latter include the renormalisation group approach to critical phenomena, the density functional theory of interfaces, the topological defects of nematic liquid crystals and the kinematic aspects of the phase transformation process. This textbook provides the student with a complete overview, intentionally at an introductory level, of the theory of phase transitions. References include suggestions for more detailed treatments and four appendices supply overviews of the mathematical tools employed in the text.

Epiphyseal Growth Plate Fractures
This comprehensive reference work covers all aspects of growth plate fractures and their complications. Following general reviews of growth plate fractures, 21 chapters deal with each epiphyseal growth plate in the body. All of these chapters are constructed similarly for easy and quick retrieval of the required information. The main emphasis is on evaluation (diagnosis) and management (treatment). A separate section is devoted to premature partial physeal arrest, as this is by far the most common and feared complication of a growth plate fracture and its treatment is involved and controversial. The case studies included are often based on 20- to 30-year follow-ups, revealing cases that originally appeared to be quite satisfactory at the conclusion of growth but were found to have turned out quite poorly years later.

In particular, research in RNA cancer epigenetics has made impressive progress in the last few years. Individual chapters in Part I (focusing on RNA epigenetics) are devoted to RNA modifications in Cancer Metabolism and Microenvironment, Cancer Stem Cell Biology, Immune Surveillance, Solid Tumors and Tumor Immunity, and Hematopoietic Malignancies, as well as to RNA editing in Cancer. Chapters in Part II and III of the book focus on histone epigenetics and DNA epigenetics, respectively.

Environmental Simulation Chambers : Application to Atmospheric Chemical Processes
Atmospheric pollution has many different detrimental impacts on air quality at urban, regional and global scales. Large volume photoreactors (often referred to as smog or simulation chambers) have been used very effectively to investigate and understand many varied aspects of atmospheric chemistry related to air pollution problems. Photochemical smog formation, which was first observed around 1945 in Los Angeles, is now a major environmental problem for all industrialised and densely populated regions of the world. Over the years many different modelling and experimental tools have been developed to analyse and simulate the complex chemical processes associated with tropspheric photooxidant formation. Work in environmental chambers has played a key role in the development of our understanding of the atmospheric chemistry associated with pollution problems on local, regional and global scales.

Environmental and Microbial Relationships
After the publication of Volume IV in 1997, the introduction of molecular methods into ecology led to significant new findings. Emphasizing these advances, the chapters for the second edition have been completely updated and revised. This volume provides insight into current research on fungal populations and communities. It focuses on fungal responses to the physical environment, interactions with other fungi, microorganisms and invertebrates, the role of fungi in ecosystem processes such as decomposition and nutrient cycling, and aspects of biogeography and conservation. Several chapters deal with various applications in, e.g. biological pest control, natural products discovery, and the degradation of toxic organic compounds. This is an invaluable source of information both for scientists who wish to update their knowledge of current progress and for graduate students interested in obtaining a first overview of this field of research.
Environmental and Health Risk Assessment and Management : Principles and Practices
The book covers the essential aspects of environmental and health law, environmental economics, applied statistical and probabilistic methods, fundamental notions of applied epidemiology and toxicology, as well as decision analysis, to provide an integrated overview of how risk assessment and management combine to produce sound societal outcomes. Risk-based methods play a pivotal role in identifying and ranking alternative, sustainable choices, while accounting for uncertainty and variability. Specifically, most reductions in risks require a balancing of the costs and benefits associated with the action to reduce exposure to a hazard and thus risk. This balancing necessarily involves linking exposure and response through causation. Fundamentally, in risk assessment and management, science and law intersect through legal and scientific causation to the point that the failure to provide a sound causal argument can make an otherwise beneficial law or regulation invalid.
Environment Learning for Indoor Mobile Robots : A Stochastic State Estimation Approach to Simultaneous Localization and Map Building
This monograph covers theoretical aspects of simultaneous localization and map building for mobile robots, such as estimation stability, nonlinear models for the propagation of uncertainties, temporal landmark compatibility, as well as issues pertaining the coupling of control and SLAM. One of the most relevant topics covered in this monograph is the theoretical formalism of partial observability in SLAM. The authors show that the typical approach to SLAM using a Kalman filter results in marginal filter stability, making the final reconstruction estimates dependant on the initial vehicle estimates. However, by anchoring the map to a fixed landmark in the scene, they are able to attain full observability in SLAM, with reduced covariance estimates.

The second part shows different aspects of entrepreneurship in a more and more globalizing world. Networking, the relationship between clusters and business innovation, economic transition and the links between social capital and business competitiveness are some of the topics.
