It is possible to weld materials as diverse as stainless steels, zirconium, titanium and uranium, but it is crucial to understand the chemical reactions likely in the surrounding welding atmosphere. This book describes all the metallurgical phenomena involved in different welding processes, from the most standard to the most modern, such as electron beam welding or high energy laser welding.

In the past, the stability of milk and milk products was the primary consideration, but this is no longer the principal objective due to the evolution of modern sanitary practices as well as pasteurization. Today, the manufacture of dairy products of consistently good flavor and texture is crucial. In previous flavor studies, researchers identified hundreds of volatile compounds, with little or no attention paid to their sensory contribution to overall flavor of dairy products. The availability of powerful chromatographic separation techniques like high resolution gas chromatography in combination with mass spectrometry and olfactory detection ports have revolutionized the work on characterization of dairy flavor. This along with recent developments in sensory methods and our increased knowledge about the genomics of diary culture organisms have allowed great advancements in our understanding of dairy flavor chemistry. Flavor of Dairy Products covers the evolution of dairy flavor research and presents updated information in the areas of instrumental analysis, biochemistry, processing and shelf-life issues related to the flavor of dairy products.

We are becoming increasingly aware of the overwhelming pollution of our limited water resources on this planet. And while many contaminants originate from Mother Earth, most water pollution comes as a direct result of anthropogenic activities. This problem has become so immense that it threatens the future of all humanity. If effective measures to reduce and/or remediate water pollution and its sources are not found, it is estimated by UN that 2.7 billion people will face water shortage by 2025 as opposed to 1.2 billion people who do not have access to clean drinking water now. Therefore, development of novel green technologies to address this major problem represents a priority of the highest importance. This book discusses green chemistry and other novel solutions to the water pollution problems which includes some interesting applications of nanoparticles. Novel Solutions to Water Pollution is a useful and informative text for those engaged in issues of water quality and water pollution remediation at operational, administrative, academic, or regulatory levels.

The key to avoidance of fatigue, which is the main cause of service failures, is good design. In the case of welded joints, which are particularly susceptible to fatigue, design rules are available. However, their effective use requires a good understanding of fatigue and an appreciation of problems concerned with their practical application. Fatigue strength of welded structures has incorporates up-to-date design rules with high academic standards whilst still achieving a practical approach to the subject. The book presents design recommendations which are based largely on those contained in recent British standards and explains how they are applied in practice. Attention is also focused on the relevant aspects of fatigue in welded joints which are not yet incorporated in codes thus providing a comprehensive aid for engineers concerned with the design or assessment of welded components or structures. Background information is given on the fatigue lives of welded joints which will enable the engineer or student to appreciate why there is such a contrast between welded and unwelded parts, why some welded joints perform better than others and how joints can be selected to optimise fatigue performance.

The history of life is a nearly four billion year old story of transformative change. This change ranges from dramatic macroscopic innovations such as the evolution of wings or eyes, to a myriad of molecular changes that form the basis of macroscopic innovations. We are familiar with many examples of innovations (qualitatively new phenotypes that can provide a critical advantage) but have no systematic understanding of the principles that allow organisms to innovate. This book proposes several such principles as the basis of a theory of innovation, integrating recent knowledge about complex molecular phenotypes with more traditional Darwinian thinking. Central to the book are genotype networks: vast sets of connected genotypes that exist in metabolism and regulatory circuitry, as well as in protein and RNA molecules. The theory can successfully unify innovations that occur at different levels of organization. It captures known features of biological innovation, including the fact that many innovations occur multiple times independently, and that they combine existing parts of a system to new purposes. It also argues that environmental change is important to create biological systems that are both complex and robust, and shows how such robustness can facilitate innovation. Beyond that, the theory can reconcile neutralism and selectionism, as well as explain the role of phenotypic plasticity, gene duplication, recombination, and cryptic variation in innovation. Finally, its principles can be applied to technological innovation, and thus open to human engineering endeavours the powerful principles that have allowed life's spectacular success.

This book addresses one of the most challenging problems that plagues the environmental field today-subsurface contamination. The past three decades have ushered in various methods for removal of organic and inorganic contaminants from the subsurface to varying degrees of effectiveness. Because of the site-to-site variability in the nature of contamination characteristics, the pattern of waste disposal and accidental releases, the site characteristics and thus contaminant behavior, and hydrologic conditions, predicting the effectiveness of one treatment method over another is a daunting task. Field demonstration of innovative technologies is a key step in their development, however, only after successful scale-up from laboratory testing. This book features chapters written by researchers who have linked laboratory- and field-scales in efforts to find creative, cost-effective methods for prediction of successful remediation of contaminated soil and ground water. State-of-the-art technologies using physicochemical removal methods and biological methods are discussed in the context of not only their effectiveness in remediating organic and inorganic wastes from various subsurface environments but also in terms of useful flask-scale methods for measuring and predicting their field-scale effectiveness. Chapters address sorption and hydrolysis of pesticides by organoclays, use of Fentons agents to destroy chlorinated solvents removed from the subsurface by granulated activated carbon, methanol flushing as a means of removing toxaphene from soils, natural attenuation as a method for effectiveness of remediation metals and biodegrading acid-mine drainage constituents, and biodegradation ofradiologically contaminated soils. Also addressed in this book are current and future methods of assessing microbiological activity potential and diversity and of modeling biodegradation, contaminant flux, and gaseous transport in the subsurface.

Rheology is, by common consent, a difficult subject and some of the theoretical components are often viewed as being of prohibitive complexity by scientists without a strong mathematical background. There are also the difficulties inherent in any multidisciplinary science like rheology for those with a specific training. Therefore, newcomers to the field are sometimes discouraged, and for them the existing texts on the subject - some of which are outstanding - are of limited assistance because of their depth of detail and highly mathematical nature.
This book introduces the subject of rheology in terms understandable to non-experts and describes the application of rheological principles to many industrial products and processes. It provides a simple but authoritative guide which shows clearly how mathematics, physics and chemistry have contributed to the development of rheology. The generic features of all liquid-like materials are summarised, i.e. viscosity, linear viscoelasticity, normal stresses and extensional viscosity. Particular systems are then discussed, i.e. polymeric liquids and suspensions. The final chapter gives an outline of the theoretical advances which have been made. Consistent notation and nomenclature have been used throughout the book, and the key textbooks and publications which will enable the reader to follow up particular topics are listed.

Consumers, regulators, and the food industry increasingly require that foods comply not only with label descriptions of food content, but also with information regarding the food's origin. For example, the wine industry has a long history of labeling wines based on varietal, regional, or age (vintage)-related properties. However, regulatory agencies are now beginning to require methods to confirm this label information. Food retailers are also facing voluntary or mandatory labeling requirements that will indicate regional or country-of-origin, species and/or varietal information. As a result, development of reliable analytical methods to confirm the authenticity of the label information is needed. This book presents the latest research on food and wine authentication. The chapters are authored by leading international scientists whose research focuses on the development and application of analytical methodologies used for the authentication of food and beverages.

The American Chemical Society (ACS) Committee on Analytical Reagents sets the specifications for most chemicals used in analytical testing. Currently, the ACS is the only organization in the world that sets requirements and develops validated methods for determining the purity of reagent chemicals. These specifications have also become the de facto standards for chemicals used in many high-purity applications. Publications and organizations that set specifications or promulgate analytical testing methods-such as the United States Pharmacopeia and the U.S. Environmental Protection Agency-specify that ACS reagent-grade purity be used in their test procedures. The Eleventh Edition incorporates the "supplements" accumulated over the past eight years, removes some obsolete test methods, improves instructions for many existing ones, and also introduces some new methods. Overall, the safety, accuracy, or ease of use in specifications for about 70 of the 430 listed reagents has been improved, and seven new reagents have been added.

This book is targeted for chemists and environmental scientists and engineers who are engaged in understanding the chemistry of high-valent iron (Ferrate) and in applications of chemical oxidants to treat contaminants in water, wastewater, and industrial effluents. This book will be of interest to biochemical engineers and microbiologists who want to understand Ferrate's disinfection performance. Additionally, the book will be of tremendous interest to graduate students who are performing research on the understanding of the mechanism of higher oxidation states of iron and in developing innovative drinking water and wastewater treatment technologies.
This book addresses synthesis and properties of Ferrate(VI), which is an environmentally friendly chemical for oxidation, coagulation, and disinfection for the multipurpose treatment of water and wastewater. It provides information on using different approaches to synthesize ferrate(VI). New processes to synthesize ferrate(VI) are detailed. Properties and generations of high oxidation states of iron including ferrate(IV) and ferrate(V) are discussed. Interestingly, possible formations of iron in unusual oxidation states, +7 and +8 are also discussed. The potential use of ferrate(VI) in high energy density rechargeable batteries is thoroughly reviewed. Chapters of the book demonstrate development of new technology for removing emerging pollutants without forming toxic side reactions or by-products. Examples include endocrine disruptors (EDs) and pharmaceuticals, which are of a great concern because of their possible toxic effects on humans and the ecology of the environment. Ferrate(VI) is an emerging water-treatment disinfectant, whichcan address the concerns raised by the currently used oxidants and disinfectants. Interestingly, ferrate(VI) does not react with the bromide ion; carcinogenic bromate ion would thus not be produced in the treatment of bromide-containing water. Ferrate(VI) can inactivate chlorine resistant bacteria. This book also provides information on the means to oxidize highly resistant organics and microorganisms in order to design appropriate remediation and water treatment technology which is cleaner and greener.
