Dissimilar Metal Joining
by Dheerendra Kumar DwivediThis volume discusses dissimilar metal joining by fusion and solid-state processes. It is a complex process due to differences in chemical compositions, physical properties, mechanical properties, and thermal properties of the parent metals to be joined. The contents focus on issues related to fusion and solid-state welding of dissimilar metals. The book is based on the fundamental and experimental investigation on methodologies used to overcome issues related to dissimilar metal joining by fusion welding (GTAW and its variant), resistance spot welding and solid state joining (friction stir welding, friction stir spot welding, and diffusion bonding) largely based on research investigation conducted at Indian Institute of Technology (IIT) Roorkee.
Dissipative Optical Solitons (Springer Series in Optical Sciences #238)
by Mário F. S. FerreiraThis book introduces the basic concept of a dissipative soliton, before going to explore recent theoretical and experimental results for various classes of dissipative optical solitons, high-energy dissipative solitons and their applications, and mode-locked fiber lasers.A soliton is a concept which describes various physical phenomena ranging from solitary waves forming on water to ultrashort optical pulses propagating in an optical fiber. While solitons are usually attributed to integrability, in recent years the notion of a soliton has been extended to various systems which are not necessarily integrable. Until now, the main emphasis has been given to well-known conservative soliton systems, but new avenues of inquiry were opened when physicists realized that solitary waves did indeed exist in a wide range of non-integrable and non-conservative systems leading to the concept of so-called dissipative optical solitons. Dissipative optical solitons have many unique properties which differ from those of their conservative counterparts. For example, except for very few cases, they form zero-parameter families and their properties are completely determined by the external parameters of the optical system. They can exist indefinitely in time, as long as these parameters stay constant. These features of dissipative solitons are highly desirable for several applications, such as in-line regeneration of optical data streams and generation of stable trains of laser pulses by mode-locked cavities.

Dissolved Air Flotation: Equipment, Best Practice and Applications (Springer Water)
by Roumen KaltchevThis book provides an overview of the dissolved air flotation clarification technology. It brings together the three strands of knowledge and experience accumulated in this field - the analysis of the main phenomena involved and the interactions between them, the equipment for its implementation and its main applications in water treatment. The author draws attention to the design and operation of the different equipment used in practice, their advantages, and disadvantages in the different fields of application of this technology.The book is intended for:•Engineers and technicians working on the design of equipment and its integration into the overall water treatment plant as well as in the operation of flotation plants.•Consultants and engineering offices, hoping that it will help them to make the most appropriate choices regarding the applications of this process, as well as in the equipment selections.•Wastewater treatment plants operators, in the hope that it will help them to optimise the operation of their plants and improve their understanding and analysis of some problems they may encounter.•Purchasers and contractors, who have to make sometime difficult choices for reducing costs and, at the same time, ensure and guarantee the long-term performance and reliability of the plant.The book is oriented towards the practical side of implementing the technology. It contains a lot of information about the equipment (much more than in all other available publications on the same subject) as well as practical comments and recommendations that are very rarely found in this kind of book, written mostly by researchers. It will appeal to specialists who are comfortable with water chemistry, but it may also be of interest to water professionals who are more interested in the equipment, design and operation of water treatment plants.
The Distance
by Helen GiltrowA dark, ultra-contemporary, and relentlessly paced debut thriller about a London society woman trying to put her secret criminal past behind her, and the hit man who comes to her with an impossible job she can't refuse.Charlotte Alton is an elegant socialite. But behind the locked doors of her sleek, high-security apartment in London's Docklands, she becomes Karla. Karla's business is information. Specifically, making it disappear. She's the unseen figure who, for a commanding price, will cover a criminal's tracks. A perfectionist, she's only made one slip in her career--several years ago she revealed her face to a man named Simon Johanssen, an ex-special forces sniper turned killer-for-hire. After a mob hit went horrifically wrong, Johanssen needed to disappear, and Karla helped him. He became a regular client, and then, one day, she stepped out of the shadows for reasons unclear to even herself. Now, after a long absence, Johanssen has resurfaced with a job, and he needs Karla's help again. The job is to take out an inmate--a woman--inside an experimental prison colony. But there's no record the target ever existed. That's not the only problem: the criminal boss from whom Johanssen has been hiding is incarcerated there. That doesn't stop him. It's Karla's job to get him out alive, and to do that she must uncover the truth. Who is this woman? Who wants her dead? Is the job a trap for Johanssen or for her? But every door she opens is a false one, and she's getting desperate to protect a man--a killer--to whom she's inexplicably drawn. Written in stylish, sophisticated prose, The Distance is a tense and satisfying debut in which every character, both criminal and law-abiding, wears two faces, and everyone is playing a double game.

The Distance Cure: A History of Teletherapy
by Hannah ZeavinPsychotherapy across distance and time, from Freud&’s treatments by mail to crisis hotlines, radio call-ins, chatbots, and Zoom sessions.Therapy has long understood itself as taking place in a room, with two (or more) people engaged in person-to-person conversation. And yet, starting with Freud&’s treatments by mail, psychotherapy has operated through multiple communication technologies and media. These have included advice columns, radio broadcasts, crisis hotlines, video, personal computers, and mobile phones; the therapists (broadly defined) can be professional or untrained, strangers or chatbots. In The Distance Cure, Hannah Zeavin proposes a reconfiguration of the traditional therapeutic dyad of therapist and patient as a triad: therapist, patient, and communication technology. Zeavin tracks the history of teletherapy (understood as a therapeutic interaction over distance) and its metamorphosis from a model of cure to one of contingent help. She describes its initial use in ongoing care, its role in crisis intervention and symptom management, and our pandemic-mandated reliance on regular Zoom sessions. Her account of the &“distanced intimacy&” of the therapeutic relationship offers a powerful rejoinder to the notion that contact across distance (or screens) is always less useful, or useless, to the person seeking therapeutic treatment or connection. At the same time, these modes of care can quickly become a backdoor for surveillance and disrupt ethical standards important to the therapeutic relationship. The history of the conventional therapeutic scenario cannot be told in isolation from its shadow form, teletherapy. Therapy, Zeavin tells us, was never just a &“talking cure&”; it has always been a communication cure.

Distance Sampling: Methods and Applications
by S. T. Buckland E. A. Rexstad T. A. Marques C. S. OedekovenIn this book, the authors cover the basic methods and advances within distance sampling that are most valuable to practitioners and in ecology more broadly. This is the fourth book dedicated to distance sampling. In the decade since the last book published, there have been a number of new developments. The intervening years have also shown which advances are of most use. This self-contained book covers topics from the previous publications, while also including recent developments in method, software and application. Distance sampling refers to a suite of methods, including line and point transect sampling, in which animal density or abundance is estimated from a sample of distances to detected individuals. The book illustrates these methods through case studies; data sets and computer code are supplied to readers through the book's accompanying website. Some of the case studies use the software Distance, while others use R code. The book is in three parts. The first part addresses basic methods, the design of surveys, distance sampling experiments, field methods and data issues. The second part develops a range of modelling approaches for distance sampling data. The third part describes variations in the basic method; discusses special issues that arise when sampling different taxa (songbirds, seabirds, cetaceans, primates, ungulates, butterflies, and plants); considers advances to deal with failures of the key assumptions; and provides a check-list for those conducting surveys.

Distillation Control
by Cecil L. SmithLearn to Design the Best Control Configuration for Any Distillation Column Today, distillation is by far the most common separation technique used in the chemical and petroleum industries. All distillation columns need to be carefully controlled in order to meet specified production and quality levels. Distillation Control enables readers to do this by approaching the subject from a process to develop, analyze, and troubleshoot all aspects of column controls. Readers are efficiency and effectiveness and minimizing coats. Distillation Control begins with a chapter dedicated to underlying principles, including separation processes, reflux and boilup ratios, and composition dynamics. Next, the author covers such critical topics as: Composition control Pressure control and condensers Reboilers and feed preheaters Application of feedforward Unit optimization Complex towers As readers progress through the text, they'll discover that the best control configuration for a distillation column is largely determined using steady-state process characteristics. The stage-by-stage separation models that the author sets forth for column design, therefore, provide information that is essential in developing the optimal control configuration. In addition to its clear explanations, Distillation Control is filled with clear diagrams and illustrations that clarify complex concepts and guide readers through multi-step procedures. Engineers as well as other professionals working in process facilities that use distillation to separate materials will fin that this book enables them to implement the latest tested and proven distillation control methods to meet their particular processing needs.
Distillation Control, Optimization, and Tuning: Fundamentals and Strategies
by Lanny RobbinsWith a focus on the fundamentals and strategies of distillation columns, this book covers the process variables for continuous distillation columns, as well as four basic control strategies and the typical cases in which they are used. The author defines the inlet and outlet streams and process variables for a distillation column and then explains the overall concept of the separation and purification that is performed. Performance and product quality are described in terms of specification requirements, and tools and techniques for the optimization of quality performance are provided. Figures and graphs are included within the reference to illustrate concepts.

Distillation Troubleshooting
by Henry Z. KisterTHE FIRST BOOK OF ITS KIND ON DISTILLATION TECHNOLOGY The last half-century of research on distillation has tremendously improved our understanding and design of industrial distillation equipment and systems. High-speed computers have taken over the design, control, and operation of towers. Invention and innovation in tower internals have greatly enhanced tower capacity and efficiency. With all these advances, one would expect the failure rate in distillation towers to be on the decline. In fact, the opposite is the case: the tower failure rate is on the rise and accelerating. Distillation Troubleshooting collects invaluable hands-on experiences acquired in dealing with distillation and absorption malfunctions, making them readily accessible for those engaged in solving today's problems and avoiding tomorrow's. The first book of its kind on the distillation industry, the practical lessons it offers are a must for those seeking the elusive path to trouble-free distillation. Distillation Troubleshooting covers over 1,200 case histories of problems, diagnoses, solutions, and key lessons. Coverage includes: * Successful and unsuccessful struggles with plugging, fouling, and coking * Histories and prevention of tray, packing, and internals damage * Lessons taught by incidents and accidents during shutdowns, commissioning, and abnormal operation * Troubleshooting distillation simulations to match the real world * Making packing liquid distributors work * Plant bottlenecks from intermediate draws, chimney trays, and feed points * Histories of and key lessons from explosions and fires in distillation towers * Prevention of flaws that impair reboiler and condenser performance * Destabilization of tower control systems and how to correct it * Discoveries from shutdown inspections * Suppression of foam and accumulation incidents A unique resource for improving the foremost industrial separation process, Distillation Troubleshooting transforms decades of hands-on experiences into a handy reference for professionals and students involved in the operation, design, study, improvement, and management of large-scale distillation.

Covering beverages from across the globe and including descriptions of the experience of tasting each drink, this book offers an accessible and comprehensive exploration of the scientific dimensions of spirits.
Distinct Element Modelling in Geomechanics
by K.R. SaxenaLinear mathematical assumptions for procedures in other branches of engineering have little relevance for geoengineering, which must accommodate non-linear behaviors. Contributors to eight papers apply the breakthrough numerical modeling Distinct Element Method (Cundall, late 1960s). The design philosophy for structures or excavations in geotechnical engineering is different from that followed for fabricated materials like steel and concrete. The designer has little data both with regard to geological weaknesses and strength and deformation characteristics of materials before finalizing the designs. Also these characteristics vary from place to place. In-situ stresses due to gravity and tectonics and transient forces imposed due to rainfall and earthquakes make the matter more complicated. The pore waters carry the load initially before passing it on to the solids. For the analytical procedure, to be realistic, it should account for large displacements and non-linear behaviour including strain-softening. Because of these considerations, the designers have followed procedures based on simplifying assumptions such as linear, small strain, elastoplastic behaviour. Numerical procedures based on such assumptions, though very popular in other branches of engineering, have made little impact in geo-engineering. An attempt has been made in this book to compile the recent use of distinct element codes for solutions of some of the problems in geomechanics — particularly those involving excavations. It is hoped that it will provide an opportunity for the fraternity of geotechnical engineers to appreciate the opening of new frontiers in the use of computers for solving more challenging geotechnical problems.

Distracted: Why Students Can't Focus and What You Can Do About It
by James M. LangKeeping students focused can be difficult in a world filled with distractions -- which is why a renowned educator created a scientific solution to one of every teacher's biggest problems.Why is it so hard to get students to pay attention? Conventional wisdom blames iPhones, insisting that access to technology has ruined students' ability to focus. The logical response is to ban electronics in class. But acclaimed educator James M. Lang argues that this solution obscures a deeper problem: how we teach is often at odds with how students learn. Classrooms are designed to force students into long periods of intense focus, but emerging science reveals that the brain is wired for distraction. We learn best when able to actively seek and synthesize new information. In Distracted, Lang rethinks the practice of teaching, revealing how educators can structure their classrooms less as distraction-free zones and more as environments where they can actively cultivate their students' attention. Brimming with ideas and grounded in new research, Distracted offers an innovative plan for the most important lesson of all: how to learn.
