The Truth Behind Earth Changes in the Coming Age of Light
Paperback ISBN: 1879181622
In Catastrophobia Barbara Hand Clow shows that a series of cataclysmic disasters 11,500 years ago rocked the world and left humanity's collective psyche chronically scarred. This unprocessed fear is responsible for our constant expectations of apocalypse, from Y2K to the famed end of the Mayan calendar in 2012. But according to the author there is every indication that the changes in consciousness over the last 30 years are the beginnings of a collective healing from these deep fears.
Treasures of the Earth
Paperback ISBN: 1770856447
"Superbly done ... should be high on everyone's 'must have' list." --Rock and Gem Agates, the first popular guide to the brilliantly banded and highly prized gemstones, sold 7,000 copies in hardcover, no doubt for the glorious color photographs that capture collectors' enthusiasm for the stones' distinctive shapes and vivid colors. Agates is a comprehensive, easy-to-use identification guide and a worldwide listing of where they are found. The book describes: - Names of agates--mineralogical, geological, local, trade, trivial - Properties of agates--e.g., color, wall-banded, level-banded, cracked, thunder eggs - Sources of agates--e.g., eruptions, lava, sediment, limestone beds, and fissures - Lapidary--sawing, grinding, sanding, polishing - Imitations and forgeries of agates - Uses of agates through the ages, with beautiful photographs of artifacts and jewelry - Early writing and collections - Use of agates in science and technology - Collecting - National and regional maps showing agate-producing areas. Amateur gemologists and agate collectors alike will find this informative and beautifully illustrated book to be an indispensable resource.
Constant-Scale Natural Boundary Mapping to Reveal Global and Cosmic Processes
Paperback ISBN: 1461477611
Whereas conventional maps can be expressed as outward-expanding formulae with well-defined central features and relatively poorly defined edges, Constant Scale Natural Boundary (CSNB) maps have well-defined boundaries that result from natural processes and thus allow spatial and dynamic relationships to be observed in a new way useful to understanding these processes. CSNB mapping presents a new approach to visualization that produces maps markedly different from those produced by conventional cartographic methods. In this approach, any body can be represented by a 3D coordinate system. For a regular body, with its surface relatively smooth on the scale of its size, locations of features can be represented by definite geographic grid (latitude and longitude) and elevation, or deviation from the triaxial ellipsoid defined surface. A continuous surface on this body can be segmented, its distinctive regional terranes enclosed, and their inter-relationships defined, by using selected morphologically identifiable relief features (e.g., continental divides, plate boundaries, river or current systems). In this way, regions of distinction on a large, essentially spherical body can be mapped as two-dimensional ‘facets’ with their boundaries representing regional to global-scale asymmetries (e.g., continental crust, continental and oceanic crust on the Earth, farside original thicker crust and nearside thinner impact punctuated crust on the Moon). In an analogous manner, an irregular object such as an asteroid, with a surface that is rough on the scale of its size, would be logically segmented along edges of its impact-generated faces. Bounded faces are imagined with hinges at occasional points along boundaries, resulting in a foldable ‘shape model.’ Thus, bounded faces grow organically out of the most compelling natural features. Obvious boundaries control the map’s extremities, and peripheral regions are not dismembered or grossly distorted as in conventional map projections. 2D maps and 3D models grow out of an object’s most obvious face or terrane ‘edges,’ instead of arbitrarily by imposing a regular grid system or using regularly shaped facets to represent an irregular surface.
Continuous and Discontinuous Modelling of Fracture in Concrete Using FEM
Hardcover ISBN: 3642284620
The book analyzes a quasi-static fracture process in concrete and reinforced concrete by means of constitutive models formulated within continuum mechanics. A continuous and discontinuous modelling approach was used. Using a continuous approach, numerical analyses were performed using a finite element method and four different enhanced continuum models: isotropic elasto-plastic, isotropic damage and anisotropic smeared crack one. The models were equipped with a characteristic length of micro-structure by means of a non-local and a second-gradient theory. So they could properly describe the formation of localized zones with a certain thickness and spacing and a related deterministic size effect. Using a discontinuous FE approach, numerical results of cracks using a cohesive crack model and XFEM were presented which were also properly regularized. Finite element analyses were performed with concrete elements under monotonic uniaxial compression, uniaxial tension, bending and shear-extension. Concrete beams under cyclic loading were also simulated using a coupled elasto-plastic-damage approach. Numerical simulations were performed at macro- and meso-level of concrete. A stochastic and deterministic size effect was carefully investigated. In the case of reinforced concrete specimens, FE calculations were carried out with bars, slender and short beams, columns, corbels and tanks. Tensile and shear failure mechanisms were studied. Numerical results were compared with results from corresponding own and known in the scientific literature laboratory and full-scale tests.
Dynamic Well Testing in Petroleum Exploration and Development
Hardcover ISBN: 0123971616
"Well test is a system engineering including well test design, pressure data acquisition and interpretation, and dynamic description of the oil/gas well and the oil/gas reservoir etc. This book combines all of these to illustrate the process and the methods of well test analysis, and provides a lot of field examples to validate them. This chapter introduces the parameters obtained from well test and the problems commonly met in fields and possibly resolved by well test and its study in different stages from exploration to development of the fields. This study for gas reservoirs can be called "dynamic description of gas reservoir" or "dynamic reservoir description"; geophysical prospecting, geology-well logging and well testing are three key technologies,and well testing has its own special and irreplaceable functions"--Provided by publisher.
