Use Components to Improve Maintainability, Reduce Complexity, and Accelerate Testing in Large Rails Applications “This book gives Ruby pros a comprehensive guide for increasing the sophistication of their designs, without having to forsake the principles of elegance that keep them in our corner of the software world.” —Obie Fernandez, author, The RailsTM 5 Way, Fourth Edition As Rails applications grow, even experienced developers find it difficult to navigate code bases, implement new features, and keep tests fast. Components are the solution, and Component-Based Rails Applications shows how to make the most of them. Writing for programmers and software team leads who are comfortable with Ruby and Rails, Stephan Hagemann introduces a practical, start-to-finish methodology for modernizing and restructuring existing Rails applications. One step at a time, Hagemann demonstrates how to revamp Rails applications to exhibit visible, provably independent, and explicitly connected parts—thereby simplifying them and making them far easier for teams to manage, change, and test. Throughout, he introduces design concepts and techniques you can use to improve applications of many kinds, even if they weren’t built with Rails or Ruby. Learn how components clarify intent, improve collaboration, and simplify innovation and maintenance Create a full Rails application within a component, from first steps to migrations and dependency management Test component-based applications, manage assets and dependencies, and deploy your application to production Identify the seams in an existing Rails application, and refactor it to extract components Master a scripted, repeatable approach for refactoring Rails applications of any size Use component-based Rails with two popular structural patterns: hexagonal and DCI architecture Leverage your new component skills with other frameworks and languages Overcome the unique challenges that arise as you componentize Rails applications If you’re ready to simplify and revitalize your complex Rails systems, you’re ready for Component-Based Rails Applications.

The emergence of Web 2.0 is provoking challenging questions for developers: What products and services can our company provide to customers and employees using Rich Internet Applications, mash-ups, Web feeds or Ajax? Which business models are appropriate and how do we implement them? What are best practices and how do we apply them? If you need answers to these and related questions, you need Unleashing Web 2.0—a comprehensive and reliable resource that guides you into the emerging and unstructured landscape that is Web 2.0. Gottfried Vossen is a professor of Information Systems and Computer Science at the University of Muenster in Germany. He is the European Editor-in-Chief of Elsevier’s Information Systems—An International Journal. Stephan Hagemann is a PhD. Student in Gottfried’s research group focused on Web technologies. Presents a complete view of Web 2.0 including services and technologies Discusses potential new products and services and the technology and programming ability needed to realize them Offers ‘how to’ basics presenting development frameworks and best practices Compares and contrasts Web 2.0 with the Semantic Web

Phase Transitions in Foods, Second Edition, assembles the most recent research and theories on the topic, describing the phase and state transitions that affect technological properties of biological materials occurring in food processing and storage. It covers the role of water as a plasticizer, the effect of transitions on mechanical and chemical changes, and the application of modeling in predicting stability rates of change. The volume presents methods for detecting changes in the physical state and various techniques used to analyze phase behavior of biopolymers and food components. It should become a valuable resource for anyone involved with food engineering, processing, storage, and quality, as well as those working on related properties of pharmaceuticals and other biopolymers. Contains descriptions of non-fat food solids as "biopolymers" which exhibit physical properties that are highly dependent on temperature, time, and water content Details the effects of water on the state and stability of foods Includes information on changes occurring in state and physicochemical properties during processing and storage The only book on phase and state transitions written specifically for the applications in food industry, product development, and research

An Innovative Approach to Studying and Treating Cancer: Targeting pH describes one of the few characteristics of cancer that is not shared by normal tissues: the reversal or inversion of the pH gradient when intracellular pH becomes alkaline and extracellular pH becomes acid. This is now recognized as one of the most selective and differential hallmarks of all cancer cells and tissues, being the opposite of the condition found in normal tissues and a potential target in order to achieve either a stable disease or even regression with no toxicity. The book discusses topics such as lactic acid and its transport system in the pH paradigm, mechanisms to decrease extra cellular pH and increase intracellular pH, NHE-1 activity in cancer, carbonic anhydrases, vacuolar ATPase proton pump, and the sodium-bicarbonate cotransporter system. Additionally, it discusses complementary pharmacological interventions, cellular acidification and extracellular alkalinization as a new and integral approach to cancer treatment. Analyzes the mechanisms that lead to the inversion of pH gradient in cancer tissues Summarizes almost 100 years of research on pH inversion in cancer in one single source, discussing the most relevant and updated researches in the field Proposes new efficient treatments against cancer using pH inversion mechanisms, either with new drugs like proton transport inhibitors and proton pump inhibitors (PTIs and PPIs) or with repurposed drugs
This open access book traces the development of sociology in Germany from the late 19th century to the present day, providing a concise overview of the main actors, institutional processes, theories, methods, topics and controversies. Throughout the book, the author relates the disciplines history to its historical, economic, political and cultural contexts. The book begins with sociology in the German Reich, the Weimar Republic, National Socialism and exile, before exploring sociology after 1945 as a key discipline of the young Federal Republic of Germany, and reconstructing the periods from 1945 to 1968 and from 1968 to 1990. The final chapters are devoted to sociology in the German Democratic Republic and the period from 1990 to the present day. This work will appeal to students and scholars of sociology, and to a general readership interested in the history of Germany. Stephan Moebius is Professor of Sociological Theory and Intellectual History at the University of Graz, Austria.
