Conformal Maps of a Riemannian Surface into the Space of Quaternions
In the present work, a coordinate-free way is suggested to handle conformal maps of a Riemannian surface into a space of constant curvature of maximum dimension 4, modeled on the non-commutative field of quaternions. This setup for the target space and the idea to treat differential 2-forms on Riemannian surfaces as quadratic functions on the tangent space, are the starting points for the development of the theory of conformal maps and in particular of conformal immersions. As a first result, very nice conditions for the conformality of immersions into 3- and 4-dimensional space-forms are deduced and a simple way to write the second fundamental form is found. If the target ...
John Neal and Nineteenth-century American Literature and Culture
John Neal and Nineteenth-Century American Literature and Culture is a critical reassessment of American novelist, editor, critic, and activist John Neal, arguing for his importance to the ongoing reassessment of the American Renaissance and the broader cultural history of the Nineteenth Century. Contributors (including scholars from the United States, Germany, England, Italy, and Israel) present Neal as an innovative literary stylist, penetrating cultural critic, pioneering regionalist, and vital participant in the business of letters in America over his sixty-year career.
Emerging Technologies for Semantic Work Environments: Techniques, Methods, and Applications
Today's work is characterized by a high degree of innovation and thus demands a thorough overview of relevant knowledge in the world and in organizations. Semantic Work Environments support the work of the user by collecting knowledge about needs and providing processed and improved knowledge to be integrated into work. Emerging Technologies for Semantic Work Environments: Techniques, Methods, and Applications describes an overview of the emerging field of Semantic Work Environments by combining various research studies and underlining the similarities between different processes, issues and approaches in order to provide the reader with techniques, methods, and applications of the study.
X-Ray Studies on Electrochemical Systems
This book is your graduate level entrance into battery, fuel cell and solar cell research at synchrotron x-ray sources and free electron lasers. Materials scientists find numerous examples for the combination of electrochemical experiments with simple and with highly complex x-ray scattering and spectroscopy methods. Physicists and chemists can link applied electrochemistry with fundamental concepts of condensed matter physics, physical chemistry and surface science.
The ACL-Deficient Knee
This book approaches the ACL deficient knee from a different perspective than those of the previous classical ways. The common approach is the analysis of closed compartments; anatomy, biomechanics, physical findings, imaging, surgical treatment and rehabilitation. The approach of this book is completely opposite, focusing on questions, controversies, problem analyses and problem solving, besides analyzing the possibility of prevention. Therefore, in each chapter, the biomechanics, anatomy, and other areas that are relevant to the topic are reviewed. There are chapters where highly specialized surgical techniques are presented (acute ACL repair, double bundle reconstruction, chondral lesions treatment or meniscal transplant). These chapters are written by internationally renowned specialists that are pioneers in the topic analyzed. Another interesting aspect of this book are the step by step surgical techniques videos, that will allow a knee specialist to perform the technique presented by the author. Moreover, the videos will include anatomy and physical therapy techniques.
Time Traveller I
If you have learned Japanese for 1 - 2 years and want to try out reading a real Japanese manga this book is for you.

The story: 14 year old Billy visits his fatherly old friend who has just finished the construction of a time machine. Accidentally Billy starts the machine and travels into the future where among other persons he meets his future son ...
Progress in Nitrogen Cycling Studies
This book contains the proceedings of the `8th Nitrogen Workshop' which was held at the University of Ghent, Belgium, from 5 to 8 September 1994. Although nitrogen dynamics in different ecosystems have been studied for several decades, new orientations and other emphases have recently emerged. Previously, nitrogen was considered as an essential element mostly in terms of productivity, but now, more emphasis is attached to environmental consequences. More than 100 contributions in this book tackle recent developments within the fields of nitrogen advice systems, plant response to fertilization, immobilization and mobilization, nitrification, denitrification, leaching, ammonia volatilization and biological nitrogen fixation. A large number of papers is devoted to the formation of gaseous nitrogen compounds, while mineralization-immobilization is another topic of important interest. The book also contains the reports of discussion groups on different aspects of the nitrogen cycle.
Illuminating the Middle Ages
The twenty-eight essays in this collection showcase cutting-edge research in manuscript studies, encompassing material from late antiquity to the Renaissance. The volume celebrates the exceptional contribution of John Lowden to the study of medieval books.
