This reference provides a practical introduction to PEAF (pragmatic enterprise architecture framework) and its use in enterprise-architecture practice for those who want to explore how to get an enterprise on track with EA.

This book takes you beyond the PHP basics to the enterprise development practices used by professional programmers. Updated for PHP 5.3 with new sections on closures, namespaces, and continuous integration, this edition will teach you about object features such as abstract classes, reflection, interfaces, and error handling. You’ll also discover object tools to help you learn more about your classes, objects, and methods. Then you’ll move into design patterns and the principles that make patterns powerful. You’ll learn both classic design patterns and enterprise and database patterns with easy-to-follow examples. Finally, you’ll discover how to put it all into practice to help turn great code into successful projects. You’ll learn how to manage multiple developers with Subversion, and how to build and install using Phing and PEAR. You’ll also learn strategies for automated testing and building, including continuous integration. Taken together, these three elements—object fundamentals, design principles, and best practices—will help you develop elegant and rock-solid systems.

Higher Education Implications for Teaching and Learning during COVID-19 provides different perspectives regarding the impact of COVID-19 on college teaching and learning and on students, both collectively and individually. Contributors argue that the pandemic forced a higher education reckoning as institutions around the world were forced to shut their physical doors and open up their online platforms in a wider capacity. While these concerns are linked to a certain point in time, there is much we can learn from collective institutional responses to the pandemic-induced pivots to virtual teaching and learning. Scholars of higher education, organizational communication, and crisis communication will find this book particularly useful.

Written and edited by world-renowned experts in the field, including Dr. Shoei K. Stephen Huang, a pioneer of radiofrequency catheter ablation procedures, Huang's Catheter Ablation of Cardiac Arrhythmias, 5th Edition, provides authoritative, comprehensive information on these increasingly used electrophysiology procedures. This outstanding resource is packed with cutting-edge content in every area of this fast-changing field, including anatomy, diagnostic criteria, differential diagnosis, mapping, and ablation. Ideal for practitioners who need a definitive, user-friendly ablation text for the electrophysiology lab or office setting, it offers quick access to practical content, using detailed tables and high-quality images to help you apply what you learn in your practice. - Reflects all the latest technology, including the new pulse field ablation (PFA) procedure, new balloon technologies (RF, laser, and PFA) for pulmonary vein isolation, and high-resolution 3D mapping systems. - Offers expert guidance on atrial tachycardia and flutter, atrial fibrillation, atrioventricular nodal reentrant tachycardia, tachycardias related to accessory atrioventricular connections, ventricular tachycardia, transseptal catheterization techniques, ablation for pediatric patients, and patient safety and complications. - Contains new chapters covering Biophysics and Clinical Applications of Laser Ablation, Biophysics and Clinical Applications of Pulse Field Ablation, Multiple Strategic Approach to Ablate Atrial Fibrillation, Ablation of Challenging/Difficult Accessory Pathways, Ablation of Ventricular Tachycardia in Arrhythmogenic Ventricular Cardiomyopathy, and more. - Contains 450 figures, including ECGs, intracardiac recordings, 3D mapping, ultrasound, fluoroscope, and ablation images. - Includes numerous tables and boxes that provide quick access to key points, arrhythmia mechanisms, diagnostic criteria, target sites for ablation, use of special equipment, complications, and troubleshooting problems and their solutions. - Provides access to 20 video clips, including transseptal access to the left atrium, intracardiac ultrasound, and techniques of pericardial access. - Any additional digital ancillary content may publish up to 6 weeks following the publication date.

This update to a Wrox bestseller dives in and guides the reader through the entire process of creating dynamic, data-driven sites using the open source "AMP" model: Apache Web server, the MySQL database system, and the PHP scripting language. The team of expert authors covers PHP scripting, database management, security, integration, and e-commerce functions and comes complete with a useful syntax reference. Showcases three fully functional Web site examples, with implementations for both Windows and Linux, that readers can incorporate into their own projects Updates include a new chapter on PHP5 features and functions, a new example Web site application, and updates to PHP5 throughout the text

Leaves are among the most abundant organs on earth and are a defining feature of most terrestrial ecosystems. However, a leaf is also a potential meal for a hungry animal and the question therefore arises, why does so much foliage survive in nature? What mechanisms protect leaves so that, on a global scale, only a relatively small proportion of living leaf material is consumed? Leaf survival is in large part due to two processes: firstly, leaf-eating organisms fall prey to predators (top-down pressure on the herbivore); secondly, leaves defend themselves (bottom-up pressure on the herbivore). Remarkably, these two types of event are often linked; they are controlled and coordinated by plants and the molecular mechanisms that underlie this are now beginning to emerge. This novel text focuses exclusively on the leaf, on the herbivorous organisms that attack leaves, and the mechanisms that plants use to defend these vital organs. It begins with an assessment of the scale of herbivory, before examining direct physical and chemical defences on leaf surfaces and within the leaf itself. Although some leaf defences are easily seen, most operate at the molecular level and are therefore invisible to the naked eye. Many of these recently elucidated mechanisms are described. Throughout the book, perspectives from both the laboratory and the field are combined. A central feature of the work is its emphasis on the coevolution of leaf defences and the digestive tracts of animals including humans, making the book of relevance in understanding the role of leaf defences in agriculture. Leaf Defence is suitable for senior undergraduate and graduate students taking courses in plant science, as well as a broader audience of biologists and biochemists seeking a comprehensive and authoritative overview of this exciting and emerging topic.
