Описание: This book investigates the evolution process of rockburst based on the energy dissipation theory and proposes appropriate active prevention and control technologies. It discusses the electromagnetic radiation (EMR) generated by coal rock fractures as a measurement of the amount of dissipated energy, and the use of EMR to experimentally observe the time domain characteristics of energy dissipation during coal rock failure processes. It then proposes the concept of the rockburst activity domain system (RADS), establishes a dynamic pressure model of rockburst, and describes the energy criterion for rockburst instability. Lastly, it presents two waterjet cutting-based cases of pressure relief and rockburst prevention. The book serves as a reference resource for mine safety workers, engineering technicians, scientists, graduate students and undergraduates engaged in research on dynamic hazards such as rockburst..

Описание: Jaynes about a decade later, applications of the concept of entropy and the principle of maximum entropy have proliterated in science and engineering. Recent years have witnessed a broad range of new and exciting developments in hydrology and water resources using the entropy concept.
Описание: Harnessing the sun’s energy via photosynthesis is at the core of sustainable production of food, fuel, and materials by plants, algae, and cyanobacteria. Photosynthesis depends on photoprotection against intense sunlight, starting with the safe removal of excess excitation energy from the light-harvesting system, which can be quickly and non-destructively assessed via non-photochemical quenching of chlorophyll fluorescence (NPQ). By placing NPQ into the context of whole-organism function, this book aims to contribute towards identification of plant and algal lines with superior stress resistance and productivity. By addressing agreements and open questions concerning photoprotection’s molecular mechanisms, this book contributes towards development of artificial photosynthetic systems. A comprehensive picture –from single molecules to organisms in ecosystems, and from leading expert’s views to practical information for non-specialists on NPQ measurement and terminology – is presented.
Описание: How did life on Earth arise, and does life have a purpose? These questions have captured the imagination of curious minds ever since the dawn of humanity. Countless myths have been told, but a plausible scientific explanation has resisted 160 years of vigorous research since Darwin. In this book, award winning physicist Karo Michaelian reviews a bold new theory founded on non-equilibrium thermodynamic principles. Life is recognized as a thermodynamic process which could only arise, proliferate, and evolve by dissipating an external generalized chemical potential. Michaelian identifies this external potential as the ultraviolet photon flux arriving at Earth's surface during the Archean. The fundamental molecules of life are recognized as UV pigments which "self-organized" under this flux. The theory is drawing a lot of attention because of its ability to explain many of the salient characteristics of the fundamental molecules of life and because it suggests that life and evolution indeed have a purpose. Large amounts of empirical data from epochs all the way back to the beginning of life and from some of Michaelian's own experiments all support the new theory. The implications are serious for many contemporary paradigms concerning life and evolution. Even the cherished Darwinian paradigm, with its implicit metaphysical "will to survive," selection only at the level of the organism, and the inescapable tautology in "survival of the survivors" (irrespective of Popper's recanting) must be reformulated on thermodynamic principles, and the way to do this is presented in the book. Michaelian concludes that life similar, and not so similar, to our own should exist everywhere in the Universe wherever there exists the organic elements, UV-C light, and a dissipative solvent medium. In fact, he suggests that we have already discovered extraterrestrial life on other planets of our own solar system, and even within the galactic interstellar clouds of gas and dust, but have yet to recognize it as such under the old paradigms. A program for best searching for this extraterrestrial life at the different stages of its dissipation development is detailed within the book. Karo Michaelian has Ph.D. in physics from the University of Alberta, Canada and has worked at various research institutes throughout the world in topics ranging from nuclear physics and nanoparticles to complex systems and non-equilibrium thermodynamics. His book makes fascinating reading in understandable language for the serious amateur but also contains much detail, including mathematical derivation of thermodynamic principles, for the professional who wants an in-depth understanding. The book contains 430 pages with 142 images and diagrams and 434 references. A historical sketch of origin and evolution of life research is presented and critically analyzed, including; Ideas from Antiquity, Darwinian Theory, the Miller Experiments, the RNA World, Hydrothermal vents, Panspermia, and Gaia Theory. The thermodynamic foundations of the new theory are developed in the first 6 chapters and the corroborating evidence presented in the next 12. Another 2 chapters discuss contemporary paradigms in need of reform, and the last discusses the probable existence of dissipative life in other parts of the Universe. Mathematical demonstrations are left to boxes that can be skipped without much loss of continuity of argument. Analogies help to make the theory understandable to those who may not have formal training in mathematics or who lack an understanding of non-equilibrium thermodynamics.

Описание: In hydraulic engineering numerous devices like stilling basins, baffled aprons, and vortex shafts are known under the collective term of energy dissipators. Their purpose is to dissipate hydraulic energy, i.e. to convert this energy mainly into heat. Dissipators are used in places where the excess hydraulic energy could cause damage such as eros

Описание: This book revisits the long-standing puzzle of cross-scale energy transfer and dissipation in plasma turbulence and introduces new perspectives based on both magnetohydrodynamic (MHD) and Vlasov models. The classical energy cascade scenario is key in explaining the heating of corona and solar wind. By employing a high-resolution hybrid (compact finite difference & WENO) scheme, the book studies the features of compressible MHD cascade in detail, for example, in order to approximate a real plasma cascade as “Kolmogorov-like” and to understand features that go beyond the usual simplified theories based on incompressible models. When approaching kinetic scales where plasma effects must be considered, it uses an elementary analysis of the Vlasov–Maxwell equations to help identify the channels through which energy transfer must be dissipated. In addition, it shows that the pressure–strain interaction is of great significance in producing internal energy. This analysis, in contrast to many other recent studies, does not make assumptions about wave-modes, instability or other specific mechanisms responsible for the dynamics – the results are direct consequences of the Vlasov–Maxwell system of equations. This is an important step toward understanding dissipation in turbulent collisionless plasma in space and astrophysics.
