Book Description
Physical Properties of Materials for Engineers, Second Edition introduces and explains modern theories of the properties of materials and devices for practical use by engineers. Introductory chapters discuss both classical mechanics and quantum mechanics to demonstrate the need for the quantum approach. Topics are presented in an uncomplicated manner; extensive cross-references are provided to emphasize the inter-relationships among the physical phenomena. Illustrations and problems based on commercially-available materials are included where appropriate. Physical Properties of Materials for Engineers, Second Edition is an excellent introduction to solid state physics and practical techniques for students and workers in aerospace industry, chemical engineering, civil engineering, electrical engineering, industrial engineering, materials science, and mechanical and metallurgical engineering.

Book Description
A supply of cold air from low velocity devices located at floor level creates a gravity current type of flow which means that the flow is governed by its negative buoyancy. The aim was to study properties of gravity currents at the conditions one has in room flow situations. Findings from both experimental work and numerical simulations are presented. The supply Archimedes number was varied within the limits one has in applications. Different shapes of terminals were tested. In the experimental work two approaches were used: (i) Scale model tests with water as operating fluid and density difference created by adding salt to the supply flow; (ii) Full scale tests in mock ups of real rooms. In the scale model both starting flow and stationary flows were studied. In a typical room flow situation with a supply device located at a wall the height of the gravity current after a some distance becomes nearly constant and the flow resembles subcritical radial flow. The decay of the velocity is then nearly inversely proportional to the distance r from the supply. The decay follows usually the relation r(-a) with 'a' varying between 0.8 to 1.3. For supply Archimedes numbers substantially greater than one there is an initial increase of the velocity and it reaches a maximum wherefrom it starts to decay. From the heat load and the width of the room the magnitude of the velocity in the room can be assessed. Two-dimensional supply at Archimedes number, Ar(s), greater than one gives rise to a critical flow with maximum velocity equal to B(1/3) (B is the specific buoyancy flux/unit width). The height, h, of the density current is equal to h/H = Ar(s)(-l /3) (H is the height of the supply device).

Book Description
This edited work contains the most recent advances related to the study of layered intrusions and cumulate rocks formation. The first part of this book presents reviews and new views of processes producing the textural, mineralogical and geochemical characteristics of layered igneous rocks. The second part summarizes progress in the study of selected layered intrusions and their ore deposits from different parts of the world including Canada, Southwest China, Greenland and South Africa. Thirty experts have contributed to this update on recent research on Layered Intrusions. This highly informative book will provide insight for researchers with an interest in geology, igneous petrology, geochemistry and mineral resources.

Book Description
Over the last two decades environmental hydraulics as an academic discipline has expanded considerably, caused by growing concerns over water environmental issues associated with pollution and water balance problems on regional and global scale. These issues require a thorough understanding of processes related to environmental flows and transport phenomena, and the development of new approaches for practical solutions. Environmental Hydraulics includes about 200 contributions from 35 countries presented at the 6th International Symposium on Environmental Hydraulics (Athens, Greece, 23-25 June 2010). They cover the state-of-the-art on a broad range of topics, including: fundamentals aspects of environmental fluid mechanics, environmental hydraulics problems of inland, coastal and ground waters, interfacial processes; computational, experimental and field measurement techniques, ecological aspects, and effects of global climate change. Environmental Hydraulics will be of interest to researchers, civil/environmental engineers, and professional engineers dealing with the design and operation of environmental hydraulic works such as wastewater treatment and disposal, river and marine constructions, and to academics and graduate students in related fields.
