The need to understand the biological processes that are important for essential aquatic and terrestrial ecosystem function has prompted much research into the field of ecological enzymology. This book presents the two broad areas of application in a compilation of reviews by 21 international experts in their respective fields. The first explores enzymatic activities to assess the processes or mechanisms that operate in a given system, such as the rhizosphere, plant leaves and shoots, soil surfaces, and biofilms.
Most ecological risk assessments consider the risk to individual organisms or organism-level attributes. From a management perspective, however, risks to population-level attributes and processes are often more relevant. Despite many published calls for population risk assessment and the abundance of available scientific research and technical tools assessing risks to populations, risk assessors worldwide still have difficulty determining how population level considerations can be integrated into environmental decision-making.
Ugural’s Mechanical Design: An Integrated Approach provides a comprehensive, unified approach to the subject of machine element design for Mechanical Engineering students and practicing engineers. The author’s expertise in engineering mechanics is demonstrated in Part I (Fundamentals), where readers are given an exceptionally strong treatment of the design process, stress & strain, deflection & stiffness, energy methods, and failure/fatigue criteria. Advanced topics in mechanics (marked with an asterisk in the Table of Contents) are provided for optional use.T
Fiber-reinforced polymer (FRP) composites have become an integral part of the construction industry because of their versatility, enhanced durability and resistance to fatigue and corrosion, high strength-to-weight ratio, accelerated construction, and lower maintenance and life-cycle costs. Advanced FRP composite materials are also emerging for a wide range of civil infrastructure applications. These include everything from bridge decks, bridge strengthening and repairs, and seismic retrofit to marine waterfront structures and sustainable, energy-efficient housing.
Airfield Safety and Capacity Improvements: Case Studies on Successful Projects presents six case studies focused on the planning, engineering, and management of major construction projects at active airports. The construction or reconstruction of runways, aprons, ramps, or terminals while an airport is open for regular operations poses complex challenges, such as access to and from airport operating areas, logistics, staging, short-term lighting and signage, airline-airport communications, and staging and planning for short-term closures of taxiways and taxi lanes.
The elements: Si, N, O, C and H, have strong chemical affinities for one another. Under the correct conditions, Si-N bonding will occur in almost any Si-N-(O/C/H), and many related, reaction systems; although Si-O and Si-C are formidable competitors to Si-N. The most favored Si-N compound is stoichiometric Si3N4. It comes in three common varieties: amorphous a-Si3N4 and crystalline [alpha]-Si3N4 or [beta]-Si3N4. How they interrelate, how one finds them and (above all) how one makes them – and how sometimes they just happen to form – are the subjects of this book, with due attention being paid to closely related matters.
The second edition of a bestseller, Mathematical Techniques in GIS demystifies the mathematics used in the manipulation of spatially related data. The author takes a step-by-step approach through the basics of arithmetic, algebra, geometry, trigonometry and calculus that underpin the management of such data. He then explores the use of matrices, determinants and vectors in the handling of geographic information so that the data may be analyzed and displayed in two-dimensional form either in the visualization of the terrain or as map projections.

Over the past decade a new and controversial energy extraction method known as hydraulic fracturing, or fracking, has rocketed to the forefront of U.S. energy production. With fracking, millions of gallons of water, dangerous chemicals, and sand are injected under high pressure deep into the earth, fracturing hard rock to release oil and gas.Wenonah Hauter, one of the nation’s leading public interest advocates, argues that the rush to fracking is dangerous to the environment and treacherous to human health.

Along with windstorms, floods are the most common and widespread of all natural disasters. Although they can often be predicted, they cause loss of life, damage and destruction, as many urban communities are located near coasts and rivers. In terms of victims, floods are responsible for more than half the deaths caused by natural catastrophes. As flood events appear to be rapidly increasing world-wide, an advanced and universal approach to urban flooding and how to manage will help reduce flood impact.T
New, significant scientific discoveries in laser and photonic technologies, systems perspectives, and integrated design approaches can improve even further the impact in critical areas of challenge. Yet this knowledge is dispersed across several disciplines and research arenas. Laser and Photonic Systems: Design and Integration brings together a multidisciplinary group of experts to increase understanding of the ways in which systems perspectives may influence laser and photonic innovations and application integration.B
This book gives background information why shale formations in the world are important both for storage capacity and enhanced gas recovery (EGR). Part of this book investigates the sequestration capacity in geological formations and the mechanisms for the enhanced storage rate of CO2 in an underlying saline aquifer.The growing concern about global warming has increased interest in geological storage of carbon dioxide (CO2). The main mechanism of the enhancement, viz., the occurrence of gravity fingers, which are the vehicles of enhanced transport in saline aquifers, can be visualized using the Schlieren technique.
Cost optimal and nearly zero energy performance levels are principles initiated by the European Union’s (EU) Energy Performance of Buildings Directive which was recast in 2010. These will be major drivers in the construction sector in the next few years, because all new buildings in the EU from 2021 onwards are expected to be nearly zero energy buildings (nZEB).
This book introduces the technical definitions, system boundaries, energy calculation methodology and input data needed to set primary energy based minimum/cost optimal and nZEB requirements in national energy frames.
Optomechatronics, as a fusion of optical and mechatronic engineering, have played a key role in developing innovative products such as high precision instruments, defence, photonic systems, measurements, diagnostics, semiconductors, and so on.

In the early days of space travel, the development of thermal protection systems for re-entry was mainly based on an experimental approach for both design of materials and testing. During this period of trial and error, the concept of ablative material was discovered resulting in the ideal matter for re-entry rockets and space vehicles to isolate and protect them from hyperthermal effects of the environment. In his book, Ablative Thermal Protection Systems Modeling, Georges Duffa explains the history of ablative materials and looks into the future of its design process.
Selected chapters from the German concrete yearbook are now being published in the new English “Beton-Kalender Series” for the benefit of an international audience.
Since it was founded in 1906, the Ernst & Sohn “Beton-Kalender” has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in “ferro-concrete” structures until – as the book’s first editor, Fritz von Emperger (1862-1942), expressed it – the “tempestuous development” in this form of construction came to an end.
Despite all the efforts being put into expanding renewable energy sources, large–scale power stations will be essential as part of a reliable energy supply strategy for a longer period. Given that they are low on CO2 emissions, many countries are moving into or expanding nuclear energy to cover their baseload supply. Building structures required for nuclear installations whose protective function means they are classified as safety–related, have to meet particular construction requirements more stringent than those involved in conventional construction.
