The minimally-invasive or endoscopic mitral valve surgery is one of the most attractive and most interesting areas of the modern heart surgery. The book describes first all practical steps necessary in a clinic from the idea of the introduction of the minimally-invasive mitral valve surgery up to practical realization of the operation program. The initial explanation of organizational and financial aspects allows an exact resource planning and protects against wrong expectations and failures. An extensive and detailed representation of the reconstruction technologies possible today as well as the specific features of her endoscopic application allow quick learning of the surgical technology. Numerous tips and tricks and informative pictures of the most frequent findings and the accompanying reconstruction technologies underline the practical orientation of the book.
Описание: Generalising Newton's law of gravitation, general relativity is one of the pillars of modern physics. While applications in the beginning were restricted to isolated effects such as a proper understanding of Mercury's orbit, the second half of the twentieth century saw a massive development of applications. These include cosmology, gravitational waves, and even very practical results for satellite based positioning systems as well as different approaches to unite general relativity with another very successful branch of physics – quantum theory. On the occassion of general relativity's centennial, leading scientists in the different branches of gravitational research review the history and recent advances in the main fields of applications of the theory, which was referred to by Lev Landau as “the most beautiful of the existing physical theories”.

Описание: This book presents all information necessary to understand the functioning of a slurry loop reactor for the polymerisation of ethylene into high density polyethylene, and to operate it accordingly. All discussions are based on experimental data from the operation of full scale commercial loop reactors. Methods for off-line modelling and scaling-up from lab to full scale are included, as well as the answers to important questions on the running of two loop reactors in series. Building knowledge from full scale industrial experience. This highly accessible book makes one understand the functioning of slurry loop reactors for the polymerisation of ethylene, and how to operate them. Its methods include off-line modelling, scaling-up and running reactors in series. It is inspiring for all production and process engineers, showing, for the first time, how with full scale reactor data the link is made between firm basic theory and the most practical operating guidelines.
Описание: Phononic crystals are artificial periodic structures that can alter efficiently the flow of sound, acoustic waves, or elastic waves. They were introduced about twenty years ago and have gained increasing interest since then, both because of their amazing physical properties and because of their potential applications. The topic of phononic crystals stands as the cross-road of physics (condensed matter physics, wave propagation in inhomogeneous and periodic media) and engineering (acoustics, ultrasonics, mechanical engineering, electrical engineering). Phononic crystals cover a wide range of scales, from meter-size periodic structures for sound in air to nanometer-size structures for information processing or thermal phonon control in integrated circuits. Phononic crystals have a definite relation with the topic of photonic crystals in optics. The marriage of phononic and photonic crystals also provides a promising structural basis for enhanced sound and light interaction. As the topic is getting popular, it is nowadays presented and discussed at various international conferences. After the first ten years during which the topic has remained mainly theoretical with a few proof-of-concept demonstrations in the literature, the evolution has been towards applications, instrumentation, and novel designs. The physical explanations for various effects are now well understood and efficient numerical methods and analysis tools have been developed. The book contains a comprehensive set of finite element model (FEM) scripts for solving basic phononic crystal problems. The scripts are short, easy to read, and efficient, allowing the reader to generate for him(her)self band structures for 2D and 3D phononic crystals, to compute Bloch waves, waveguide and cavity modes, and more.
Описание: In 1912, the Chemistry Nobel Prize was awarded for the discovery of the so-called Grignard reagents. Nowadays, many transition metal variants are developed to modify reactivity and selectivity of the C–C bond formation reaction. The Grignard reaction is one of the fundamental organometallic reactions, often used in alcohol syntheses. With transition metals like iron, cobalt and nickel or with noble metals like copper, silver and palladium, modern Grignard reagents can be designed in reactivity, selectivity and functional group tolerance. This book, written by international experts, presents an overview on timely Grignard chemistry involving transition metals.

Описание: Scientometrics have become an essential element in the practice and evaluation of science and research, including both the evaluation of individuals and national assessment exercises. Yet, researchers and practitioners in this field have lacked clear theories to guide their work. As early as 1981, then doctoral student Blaise Cronin published "The need for a theory of citing" —a call to arms for the fledgling scientometric community to produce foundational theories upon which the work of the field could be based. More than three decades later, the time has come to reach out the field again and ask how they have responded to this call. This book compiles the foundational theories that guide informetrics and scholarly communication research. It is a much needed compilation by leading scholars in the field that gathers together the theories that guide our understanding of authorship, citing, and impact.
Описание: Research in Colonial and Postcolonial Linguistics has experienced a significant increase in contributions from varying fields of language studies, gaining the attention of scholars from all over the world. This volume aims to showcase the variety of topics relevant to the study of language(s) in colonial, postcolonial and decolonial contexts. A main reason of this variety is that the new paradigm invites and necessitates research on different subject matters such as language typology, grammar and cross-linguistics, meta-linguistics and research on language ideology, discourse analysis and pragmatics. The contributions of this volume are selected, peer-reviewed papers which were partly invited and partly given at the First Bremen Conference on Colonial and Postcolonial Linguistics, held in September 2013.
Описание: Die Reihe REVISIONEN. GRUNDBEGRIFFE DER LITERATURTHEORIE setzt sich zum Ziel, die im Zuge der Diskussionen der letzten Jahre fragwurdig bzw. problematisch gewordenen Zentralbegriffe der Literaturwissenschaft zu reflektieren und zu perspektivieren.

Die aus internationalen Fachtagungen hervorgegangenen Beitrage der einzelnen Bande befassen sich in systematischer, kompendienhafter Geschlossenheit mit verschiedenen Aspekten des jeweiligen Begriffs. Eine klare Rahmenstruktur, eine kontextstiftende, ausfuhrliche Einleitung sowie ein Register machen die Bande zu problemorientierten Handbuchern. Sie sind interdisziplinar ausgerichtet und beziehen neben der Literaturwissenschaft auch Kunstgeschichte, Musik, Philosophie, Linguistik und Psychologie mit ein. Die Reihe richtet sich an theoretisch interessierte Literaturwissenschaftler aller Philologien. Sie wird ca. 8 Bande umfassen.
Описание: Culture and conflict unavoidably go together. The very idea of culture is marked by the notion of difference and creative, i.e. conflictual, interaction that inevitably support the key themes of the study of culture such as identity and diversity, memory and trauma, the translation of cultures and globalization, dislocation and emplacement, mediation and exclusion. This series publishes theoretically informed original scholarship from the fields of literary and cultural studies as well as media, visual and film studies, fostering a plural disciplinary dialogue on the multiple ways in which conflict supports and constrains the production of meaning in modernity, how the representation of conflict works, how it relates to the past and projects the present and how it frames scholarship within the humanities.

Описание: Architectural realisation of a building and its opening to the public with a range of services are central components of the building and design process of libraries. Post-Occupancy Evaluation (POE) is the final step in this process. It provides a opportunity to assess whether the construction and design of the building has indeed met the library's and users' requirements and how effectively the building functions.

Описание: Brownian motion is one of the most important stochastic processes in continuous time and with continuous state space. Within the realm of stochastic processes, Brownian motion is at the intersection of Gaussian processes, martingales, Markov processes, diffusions and random fractals, and it has influenced the study of these topics. Its central position within mathematics is matched by numerous applications in science, engineering and mathematical finance. Often textbooks on probability theory cover, if at all, Brownian motion only briefly. On the other hand, there is a considerable gap to more specialized texts on Brownian motion which is not so easy to overcome for the novice. The authors’ aim was to write a book which can be used as an introduction to Brownian motion and stochastic calculus, and as a first course in continuous-time and continuous-state Markov processes. They also wanted to have a text which would be both a readily accessible mathematical back-up for contemporary applications (such as mathematical finance) and a foundation to get easy access to advanced monographs. This textbook, tailored to the needs of graduate and advanced undergraduate students, covers Brownian motion, starting from its elementary properties, certain distributional aspects, path properties, and leading to stochastic calculus based on Brownian motion. It also includes numerical recipes for the simulation of Brownian motion.
Progress in low-dimensional topology has been very quick in the last three decades, leading to the solutions of many difficult problems. Among the earlier highlights of this period was Casson's λ-invariant that was instrumental in proving the vanishing of the Rohlin invariant of homotopy 3-spheres. The proof of the three-dimensional Poincare conjecture has rendered this application moot but hardly made Casson's contribution less relevant: in fact, a lot of modern day topology, including a multitude of Floer homology theories, can be traced back to his λ-invariant.
The principal goal of this book, now in its second revised edition, remains providing an introduction to the low-dimensional topology and Casson's theory; it also reaches out, when appropriate, to more recent research topics. The book covers some classical material, such as Heegaard splittings, Dehn surgery, and invariants of knots and links. It then proceeds through the Kirby calculus and Rohlin's theorem to Casson's invariant and its applications, and concludes with a brief overview of recent developments.
The book will be accessible to graduate students in mathematics and theoretical physics familiar with some elementary algebraic and differential topology, including the fundamental group, basic homology theory, transversality, and Poincare duality on manifolds.
