Porous media are ubiquitous throughout nature and in many modern technologies. Because of their omnipresent nature, porous media are studied to one degree or another in almost all branches of science and engineering. This text is an outgrowth of a two-semester graduate course on multiscale porous media offered to students in applied math, physics, chemistry, engineering (civil, chemical, mechanical, agricultural), and environmental and soil science. The text is largely based on Dr Cushmans' groups efforts to build a rational approach to studying porous media over a hierarchy of spatial and temporal scales. No other text covers porous media on scales ranging from angstroms to miles. Nor does any other text develop and use such a diversity of tools for their study. The text is designed to be self-contained, as it presents all relevant mathematical and physical constructs.

Over the past 25 years, the field of VUV physics has undergone significant developments as new powerful spectroscopic tools, VUV lasers, and optical components have become available. This volume is aimed at experimentalists who are in need of choosing the best type of modern instrumentation in this applied field. In particular, it contains a detailed chapter on laboratory sources. This volume provides an up-to-date description of state-of-the-art equipment and techniques, and a broad reference bibliography. It treats phenomena from the standpoint of an experimental physicist, whereby such topics as imaging techniques (NMR, X-ray, ultrasonic, etc.) computer modeling, eletro-kinetic phenomena, diffusion, non-linear wave propagation surface adsorption/desorption, convective mixing, and fracture are specifically addressed.

The study of heat and fluid flow in fluid-saturated porous media is applicable in a very wide range of fields, with practical applications in modern industry and environmental areas, such as nuclear waste management, the construction of thermal insulators, geothermal power, grain storage and many more. The vast amount of theoretical and experimental work reported has attracted the attention of industrialists, engineers, applied mathematicians, chemical, civil, environmental, mechanical and nuclear engineers, physicists, food scientists, medical researchers, etc. This book covers the full range of theoretical, computational and experimental approaches to the subject, grouped into reviews of: fundamentals, stability, anisotropy, permeability and non-equilibrium, applications, and experimental porous media.
