Book Description
The rapid growth of interest in powders and their surface properties in many diverse industries prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. It is intended as an introduction to some of the elementary theory and experimental methods used to study the surface area, porosity and density of powders. It may be found useful by those with little or no training in solid surfaces who have the need to quickly learn the rudiments of surface area, density and pore-size measurements. Syosset, New York S.

Book Description
Focuses on the effects of porosity and microcracking on the physical properties of ceramics, particularly nominally single phase ceramics. The book elucidates the fundamental interrelationships determining the development and use of materials for actual and potential engineering needs. It aims to help in the understanding of porosity effects on other materials, from ceramic composties, cements and plasters to rocks, metals and polymers.;College or university bookshops may order five or more copies at a special student price, available on request.

Book Description
This book provides a fundamental understanding of physical properties of foods. It is the first textbook in this area and combines engineering concepts and physical chemistry. Basic definitions and principles of physical properties are discussed as well as the importance of physical properties in the food industry and measurement methods. In addition, recent studies in physical properties are summarized. The material presented is helpful for students to understand the relationship between physical and functional properties of raw, semi-finished, and processed food in order to obtain products with desired shelf-life and quality.

Book Description
Welcome to Porous City! Welcome to a porous society! Welcome to cities that want to be open and porous! Our cities consist of buildings that are introverted and not mixed with urban life. They are closed. How to open them? How can we introduce pockets for encounters, for streams of circulation, for green areas, for tunnels of cooling ... What logics can be imagined in our towers to allow for this openness? Using stepped floors? Creating grottos? Splitting towers? Twisting blocks? Every hypothesis leads to a series of interventions. How far can we go before the tower collapses, before it is unaffordable? Together, these series form an army of towers that contributes to a more porous city. Why wait?

Book Description
Mechanics and Physics of Porous Solids addresses the mechanics and physics of deformable porous materials whose porous space is filled by one or several fluid mixtures interacting with the solid matrix. Coussy uses the language of thermodynamics to frame the discussion of this topic and bridge the gap between physicists and engineers, and organises the material in such a way that individual phases are explored, followed by coupled problems of increasing complexity. This structure allows the reader to build a solid understanding of the physical processes occurring in the fluids and then porous solids. Mechanics and Physics of Porous Solids offers a critical reference on the physics of multiphase porous materials - key reading for engineers and researchers in structural and material engineering, concrete, wood and materials science, rock and soil mechanics, mining and oil prospecting, biomechanics.

Book Description
An invaluable reference for graduate students and academic researchers, this book introduces the basic terminology, methods and theory of the physics of flow in porous media. Geometric concepts, such as percolation and fractals, are explained and simple simulations are created, providing readers with both the knowledge and the analytical tools to deal with real experiments. It covers the basic hydrodynamics of porous media and how complexity emerges from it, as well as establishing key connections between hydrodynamics and statistical physics. Covering current concepts and their uses, this book is of interest to applied physicists and computational/theoretical Earth scientists and engineers seeking a rigorous theoretical treatment of this topic. Physics of Flow in Porous Media fills a gap in the literature by providing a physics-based approach to a field that is mostly dominated by engineering approaches.

Book Description
This book is on oil and natural gas well logging, and is based on the author's lectures at the University of Southern California. The first seven chapters discuss logging techniques and devices: spontaneous potential, gamma rays, resistivity, density, neutron logs, and acoustic logs. The remaining chapters discuss the various methods for integrating and analyzing this data.
