Discover how to use HILIC to analyze and better understand polar compounds An increasingly popular analytical method, hydrophilic interaction chromatography (HILIC) has the ability to retain and separate polar compounds that are often difficult to analyze by reversed-phase high-performance liquid chromatography (HPLC) or other analytical methods. Offering a comprehensive review, this book enables readers to develop a fundamental understanding of how HILIC works and then apply that knowledge to develop and implement a variety of practical applications. Hydrophilic Interaction Chromatography begins with discussions of HILIC retention mechanisms, stationary phases, and general method development. This sets the foundation for the book's extensive coverage of applications. The authors address unique separation challenges for bioanalytical, environmental, pharmaceutical, and biochemical applications. Moreover, there is a thorough discussion of HILIC in two-dimensional chromatography. With contributions from leading analytical scientists who have extensive experience in HILIC as well as HPLC, Hydrophilic Interaction Chromatography serves as a practical guide for researchers, featuring: Detailed examples of HILIC methods and development approaches Thorough explanations of retention mechanisms and the impact of stationary phase and mobile phase properties on separations Step-by-step guidance for developing efficient, sensitive, and robust HILIC methods References to the primary literature at the end of each chapter Hydrophilic Interaction Chromatography is written for scientists who use or develop analytical methods for the separation of polar compounds. In particular, these researchers will discover how HILIC can be used to analyze and better understand the composition of pharmaceutical, bioanalytical, biochemical, chemical, food, and environmental samples.

Explores the role of oral interaction for second language learning from cognitive, social, pedagogical and linguistic perspectives, with a focus on research relevant to English language learners aged 5-18 in a variety of classroom contexts.

How to make customers feel good about doing what you want Learn how companies make us feel good about doing what they want. Approaching persuasive design from the dark side, this book melds psychology, marketing, and design concepts to show why we’re susceptible to certain persuasive techniques. Packed with examples from every nook and cranny of the web, it provides easily digestible and applicable patterns for putting these design techniques to work. Organized by the seven deadly sins, it includes: Pride – use social proof to position your product in line with your visitors’ values Sloth – build a path of least resistance that leads users where you want them to go Gluttony – escalate customers’ commitment and use loss aversion to keep them there Anger – understand the power of metaphysical arguments and anonymity Envy – create a culture of status around your product and feed aspirational desires Lust – turn desire into commitment by using emotion to defeat rational behavior Greed – keep customers engaged by reinforcing the behaviors you desire Now you too can leverage human fallibility to create powerful persuasive interfaces that people will love to use – but will you use your new knowledge for good or evil?

Dialogue management technology has developed rapidly over the years resulting in real-time applications like telephony directories, timetable enquiries, and in-car applications. However, the current technology is still largely based on models that use rigid command language type interactions, and the users need to adapt their human communication strategies to the needs of the technology. As an increasing number of interactive ubiquitous applications will appear, challenges for interaction technology concern especially natural, more human-friendly communication. Recent research has focused on developing speech-based interactive systems that aim to increase the system’s communicative competence. By including aspects of interaction beyond simple speech recognition and question-answer based interaction, applications with more conversational interfaces have become possible. New dialogue management technology needs to address the challenges in human-technology interaction, so that smart environments should not only enable user-controlled command interfaces but equip applications with a capability that affords easy and friendly interactions with the user. Dialogue Modelling: Speech Interaction and Rational Agents provides an overview of the current dialogue technology and research trends in spoken dialogue systems, presenting a coherent perspective of AI-based cooperative interaction management. The book complements existing research regarding human-computer interfaces, speech and language technology, and communication studies in general, bringing different view-points together and integrating them into a single point of reference. Constructive Dialogue Modelling: Presents a guide to spoken dialogue technology and current research trends. Provides an overview of human factors in dialogue systems and delivers a new metaphor for human-computer interaction and computer as agent. Explains the architecture of dialogue systems using examples from systems such as Interact and DUMAS Offers a comprehensive overview of original research into the new trends in speech dialogue technology in light of innovations such as ubiquitous computing. This book will provide essential reading for industrial designers and interface engineers, university researchers and teachers, computer scientists, human communication researchers, speech and language technologists, cognitive engineers/cognitive scientists, as well as social and media researchers, and psychologists. Advanced students and researchers in computer science, speech and language technologies, psychology and communication research will find this text of interest.

A comprehensive, practical approach to three powerful methods of polymer analysis and characterization This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers—light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Featuring numerous up-to-date examples of experimental results obtained by light scattering, SEC, and A4F measurements, Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation takes an all-in-one approach to deliver a complete and thorough explanation of the principles, theories, and instrumentation needed to characterize polymers from the viewpoint of their molar mass distribution, size, branching, and aggregation. This comprehensive resource: Is the only book gathering light scattering, size exclusion chromatography, and asymmetric flow field flow fractionation into a single text Systematically compares results of size exclusion chromatography with results of asymmetric flow field flow fractionation, and how these two methods complement each other Provides in-depth guidelines for reproducible and correct determination of molar mass and molecular size of polymers using SEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, and characterization of polymer branching Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation should be of great interest to all those engaged in the polymer analysis and characterization in industrial and university research, as well as in manufacturing quality control laboratories. Both beginners and experienced can confidently rely on this volume to confirm their own understanding or to help interpret their results.

This book provides a detailed description of various multidimensional chromatographic separation techniques. The editor first provides an introduction to the area and then dives right into the various complex separation techniques. While still not used routinely comprehensive chromatography techniques will help acquaint the readers with the fundamentals and possible benefits of multi-dimensional separations coupled with mass spectrometry. The topics include a wide range of material that will appease all interested in either entering the field of multidimensional chromatography and those looking to gain a better understanding of the topic.
