Gaseous Detonation Physics and Its Universal Framework Theory (Shock Wave and High Pressure Phenomena)

by Zonglin Jiang Honghui Teng

This book highlights the theories and research progress in gaseous detonation research, and proposes a universal framework theory that overcomes the current research limitations. Gaseous detonation is an extremely fast type of combustion that propagates at supersonic speed in premixed combustible gas. Being self-sustaining and self-organizing with the unique nature of pressure gaining, gaseous detonation and its gas dynamics has been an interdisciplinary frontier for decades. The research of detonation enjoyed its early success from the development of the CJ theory and ZND modeling, but phenomenon is far from being understood quantitatively, and the development of theories to predict the three-dimensional cellular structure remains a formidable task, being essentially a problem in high-speed compressible reacting flow. This theory proposed by the authors’ research group breaks down the limitation of the one-dimensional steady flow hypothesis of the early theories, successfully correlating the propagation and initiation processes of gaseous detonation, and realizing the unified expression of the three-dimensional structure of cell detonation. The book and the proposed open framework is of high value for researchers in conventional applications such as coal mine explosions and chemical plant accidents, and state-of-the-art research fields such as supernova explosion, new aerospace propulsion engines, and detonation-driven hypersonic testing facilities. It is also a driving force for future research of detonation.

Gaseous Electronics: Tables, Atoms, and Molecules

by Gorur Govinda Raju

With the constant emergence of new research and application possibilities, gaseous electronics is more important than ever in disciplines including engineering (electrical, power, mechanical, electronics, and environmental), physics, and electronics. The first resource of its kind, Gaseous Electronics: Tables, Atoms, and Molecules fulfills the author’s vision of a stand-alone reference to condense 100 years of research on electron-neutral collision data into one easily searchable volume. It presents most—if not all—of the properly classified experimental results that scientists, researchers, and students require for a theoretical and practical understanding of collision properties and their impact. An unprecedented collection and analysis of electron neutral collision properties This book follows a new user-friendly format that enables readers to easily retrieve, analyze, and apply specific atomic/molecular information as needed. In his previous work, Gaseous Electronics: Theory and Practice, the author first explored electron–neutron interactions. To clarify the complex fundamental processes involved, he cited as much experimental data on atoms and molecules as limited space would allow. Completing that task, this handy reference more fully compiles essential revised data on more than 420 atoms and molecules, arranging it into easily digestible chapters, sections, and appendices. Analysis parameters include total scattering, ionization, excitation, attachment cross sections, ionization and attachment coefficients, attachment rates, and ion drift velocity. Some recent research areas in gaseous electronics include: Environmentally efficient and protective lighting devices Plasma research for power generation and space applications Medical applications (some involving skin treatment and healing) Written entirely in SI units, the book includes hundreds of tables, figures, and specially drawn charts, with data expressed in both tabular and graphical form. Each chapter stands independently and contains references for further research.

Gashydrate – Eine Einführung in Grundlagenforschung und Anwendung

by Judith M. Schicks

Gashydrate, auch „brennendes Eis“ genannt, sind faszinierende, eisähnliche Feststoffe, die aus Wasser- und Gasmolekülen aufgebaut sind und weltweit an allen aktiven und passiven Kontinentalhängen und in Permafrostgebieten vorkommen. Doch ihr unauffälliges Erscheinungsbild täuscht: Die Einschlussverbindungen können beachtliche Mengen Methangas enthalten. Daher besteht einerseits die Hoffnung auf einen möglichen neuen Energieträger und andererseits die Sorge um eine nicht zu unterschätzende Quelle an klimaschädlichem Methangas. Gashydrate, hat die neueste Forschung gezeigt, bieten zudem in vielen Bereichen industrieller Anwendung eine durchaus vielversprechende Alternative zu konventionellen Verfahren.Das vorliegende Buch gibt eine Einführung in die physikalisch-chemischen Grundlagen der Hydratbildung und die Strukturen der Gashydratphasen. Basierend auf diesem grundlegenden Verständnis erklärt es die natürlichen Gashydratvorkommen und zeichnet mögliche Methoden des Abbaus und der Gewinnung von Methangas auf. Es beleuchtet Risiken, die von den Gashydratvorkommen in der Natur ausgehen könnten, und führt in die Möglichkeiten der Nutzung dieser Einschlussverbindungen in verschiedenen industriellen Anwendungsbereichen wie z.B. der Aufbereitung von Abwässern oder der Speicherung von Gasen ein.Zielgruppe dieser kompakten Einführung in die verschiedenen Aspekte der Gashydratforschung sind Studierende der Chemie und Geowissenschaften, Ingenieure, Techniker oder auch Wissenschaftler.

Gasification Processes

by Petr A. Nikrityuk Bernd Meyer

Bridging the gap between the well-known technological description of gasification and the underlying theoretical understanding, this book covers the latest numerical and semi-empirical models describing interphase phenomena in high-temperature conversion processes. Consequently, it focuses on the description of gas-particle reaction systems by state-of-the-art computational models in an integrated, unified form. Special attention is paid to understanding and modeling the interaction between individual coal particles and a surrounding hot gas, including heterogeneous and homogeneous chemical reactions inside the particle on the particle interface and near the interface between the solid and gas phases. While serving the needs of engineers involved in industrial research, development and design in the field of gasification technologies, this book's in-depth coverage makes it equally ideal for young and established researchers in the fields of thermal sciences and chemical engineering with a focus on heterogeneous and homogeneous reactions.

Gasotransmitters: Physiology and Pathophysiology

by Guzel F. Sitdikova Thomas M. Weiger Anton Hermann

Since the epochal discovery of the radical and highly toxic gas nitric oxide (NO) as a signaling molecule, two other no less toxic gases - carbon monoxide (CO) and hydrogen sulfide (H2S) - have been found to also be involved in a plethora of physiological and pathophysiological functions. The gases termed gasotransmitters play an increasingly important role in understanding how signalling into and between cells is modulated and fine-tuned. The advent of gasotransmitters has profoundly changed our way of thinking about biosynthesis, liberation, storage and action mechanisms in cellular signaling. In recent years an impressive amount of new data, distributed throughout the existing literature, has been generated. For this book the editors have recruited distinguished colleagues in the field to summarize and review important biological, pharmacological and medical functions and their implications, as well as methods for the detection of gasotransmitters.

Gasotransmitters in Plants

by Lorenzo Lamattina Carlos García-Mata

This book describes the three gasotransmitters nitric oxide (NO), hydrogen sulphide (H2S) and carbon monoxide (CO) and their function as intracellular signalling molecules in plants. Common properties are shared by NO, H2S and CO: they are beneficial at low concentrations but hazardous in higher amounts; they are small molecules of gas; they can freely cross cell membranes; their effects do not rely on receptors; they are generated enzymatically and their production is regulated; their functions can be mimicked by exogenous application; and their cellular effects may or may not be mediated by second messengers, but have specific cellular and molecular targets. In plants, many aspects of the biology of gasotransmitters remain completely unknown and generate intriguing questions, which will be discussed in this book.

Gasotransmitters Signaling in Plants under Challenging Environment (Plant in Challenging Environments #5)

by Tariq Aftab Francisco J. Corpas

Abiotic stressors, such as drought, extreme temperatures, heavy metals, or high salinity, are causing huge crop losses worldwide. These abiotic stressors are expected to become more extreme, less predictable, and more widespread in the near future. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Research on gasotransmitters is rapidly expanding and knowledge regarding the potential of gasotransmitters in biology and medicine is accumulating. Over the past few decades, the roles of these signaling molecules, especially NO and H2S, have been extensively studied for their application in plants. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitters signaling pathways. Given the multidimensional role of these signaling molecules, research over the past decades in mitigating abiotic stresses in plant biology and from an agriculture point of view, we intend to bring forth a comprehensive volume “Gasotransmitters Signaling in Plants under Challenging Environment". We are hopeful that this comprehensive volume will furnish the requisite of all those who are working or have an interest in the proposed topic

Gaston Bachelard: Critic of Science and the Imagination (Routledge Studies in Twentieth-Century Philosophy #Vol. 9)

by Cristina Chimisso

In this new study, Cristina Chimisso explores the work of the French Philosopher of Science, Gaston Bachelard (1884-1962) by situating it within French cultural life of the first half of the century. The book is introduced by a study - based on an analysis of portraits and literary representations - of how Bachelard's admirers transformed him into the mythical image of the Philosopher, the Patriarch and the 'Teacher of Happiness'. Such a projected image is contrasted with Bachelard's own conception of philosophy and his personal pedagogical and moral ideas.This pedagogical orientation is a major feature of Bachelard's texts, and one which deepens our understanding of the main philosophical arguments. The primary thesis of the book is based on the examination of the French educational system of the time and of French philosophy taught in schools and conceived by contemporary philosophers. This approach also helps to explain Bachelard's reception of psychoanalysis and his mastery of modern literature. Gaston Bachelard: Critic of Science and the Imagination thus allows for a new reading of Bachelard's body of work, whilst at the same time providing an insight into twentieth century French culture.

The book not only reviews what has changed in the field of gastric cancer over the past quarter century but also offers the reader a glimpse of the future by describing the ongoing surgical and oncological trials which focus on new treatment frontiers such as immunotherapy and target therapy. It also seeks to incorporate the latest discoveries based on molecular classifications. Further, the book reflects the findings and experiences of Italian experts belonging to the GIRCG (Italian Research Group for Gastric Cancer) and will offer an excellent guide for oncological surgeons in their daily practice of caring for patients affected by gastric cancer.

The Gastro-Archeologist: Revealing the Mysteries of the Intestine and its Diseases

by Jeremy Woodward

In order to understand common conditions such as coeliac disease and Crohn’s disease, one must view the gut in its evolutionary context. This is the novel approach to the gut and its diseases that is adopted in this book. The first part tells the story of the evolution of the gut itself – why it came about and how it has influenced the evolution of animals ever since. The second part focuses on the evolution of immunity and how the layers of immune mechanisms are retained in the gut, resembling the strata revealed in an archeological dig. The final part, ‘The Gastro-Archeologist’, ties the first two together and highlights how understanding the gut and immune system in their evolutionary context can help us understand diseases affecting them.Ambitious in its scope but telling a unique story from a refreshingly novel perspective, the book offers an informative and enjoyable read. As the story of the gut, immunity and disease unfolds, the author aims to endow readers with the same sense of awe and excitement that the subject evokes in him. Difficult concepts are illustrated using simple and colourful analogies, and the main content is supplemented with anecdotes and unusual and amusing facts throughout the book. The book is intended for anyone with an interest in the gut, its immunity and diseases, ranging from school and college biology and biomedical students, to professionals working in the field, and to patients suffering from intestinal diseases who want to understand more about their conditions.

In diesem Praxisbuch haben Experten auf diesem Gebiet das aktuelle Wissen zur Differenzialdiagnostik und zur Therapie - konservativ bis operativ - zusammengefasst.Das klinische Bild der Refluxkrankheit ist sehr vielfältig. Neben den klassischen Symptomen Sodbrennen und Schmerz hinter dem Brustbein können auch atypische Beschwerden wie Asthma, chronischerer Husten und Heiserkeit als Folge der Refluxerkrankung auftreten. Im schlimmsten Fall kann sich auch als Folge eines langjährigen Refluxes Speiseröhrenkrebs bilden. Insbesondere bei atypischen Symptomen ist aber die Diagnostik erschwert. Hier muss die klinische Expertise durch differenzierten Einsatz von apparativer Diagnostik ergänzt werden. Dieses Praxisbuch leistet eine Hilfestellung in der Funktionsdiagnostik und erläutert mögliche Diagnoseverfahren. Im Therapieteil werden konservative wie auch operative Optionen mit notwendigen Indikationen aufgezeigt. Kapitel zu den Besonderheiten bei Kindern mit Reflux und einem Auftreten bestimmter Symptome während der Schwangerschaft runden das Buch ab. Die Inhalte orientieren sich an der aktualisierten Leitlinie „Gastroösophageale Refluxkrankheit“.Neben der hohen Prävalenz und der deutlichen Einschränkung der Lebensqualität liegt die Bedeutung der Erkrankung im breiten klinischen Spektrum an Symptomen, Komplikationen und Folgeerkrankungen mit Relevanz für zahlreiche Fachdisziplinen auch außerhalb der Gastroenterologie. So bietet dieses Buch einen kompakten Wissenstranfer zum Krankheitsbild - nicht nur für Gastroenterologen.

Gated Communities and the Digital Polis: Rethinking Subjectivity, Reality, Exclusion, and Cooperation in an Urban Future (Advances in 21st Century Human Settlements)

by Kon Kim Heewon Chung

This edited collection provides an alternative discourse on cities evolving with physically and virtually networked communities—the ‘digital polis’—and offers a variety of perspectives from the humanities, media studies, geography, architecture, and urban studies. As an emergent concept that encompasses research and practice, the digital polis is oriented toward a counter-mapping of the digital cityscape beyond policing and gatekeeping in physical and virtual gated communities. Considering the digital polis as offering potential for active support of socially just and politically inclusive urban circumstances in ways that mirror the Greek polis, our attention is drawn towards the interweaving of the development of digital technology, urban space, and social dynamics. The four parts of this book address the formation of technosocial subjectivity, real-and-virtual combined urbanity, the spatial dimensions of digital exclusion and inclusion, and the prospect of emancipatory and empowering digital citizens. Individual chapters cover varied topics on digital feminism, data activism, networked individualism, digital commons, real-virtual communalism, the post-family imagination, digital fortress cities, rights to the smart city, online foodscapes, and open-source urbanism across the globe. Contributors explore the following questions: what developments can be found over recent decades in both physical and virtual communities such as cyberspace, and what will our urban future be like? What is the ‘digital polis’ and what kinds of new subjectivity does it produce? How does digital technology, as well as its virtuality, reshape the city and our spatial awareness of it? What kinds of exclusion and cooperation are at work in communities and spaces in the digital age? Each chapter responds to these questions in its own way, navigating readers through routes toward the digital polis.Chapter "Introduction - The digital polis and its practices: Beyond gated communities" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Gateway to the Heavens: How Geometric Shapes, Patterns and Symbols Form Our Reality (Gateway Series #1)

by Karen L. French

Simple geometric shapes and symbols combine to make the universal, powerful, sacred model Karen French calls Gateway to the Heavens. In this book, French explains the meaning and purpose of these shapes, how they mold our reality and perception of it and how they have a direct bearing on what you are and why you are here. These shapes and symbols contain messages that have been consistently represented in religion, philosophy, mythology, mysticism, the arts and sciences. Their messages are built into our genetic make-up and we recogniZe them instinctively. The book is divided up into 3 parts. Part 1 covers the properties of the basic geometric shapes and numbers. Part 2 describes how these, in turn, form layers of construction, creating principals that are fundamental to the purpose of the universe; the spiral sustains reality, the cross highlighting the central point of existence and the heart is where we weigh up our choices. Part 3 describes how we can use these principals to create positive change in our lives by helping us to expand our awareness of reality.
