This book is for those new to programming or that know other programming languages and would like to know Ruby. The book teaches the fundamentals of object-oriented programming and starts with creating a basic program. Everything is covered such as control structures and variables, taking input, and creating output. Moving from the basic to more advanced topics, a solid understanding of Ruby is taught in logical progression. The book ends with an overview of the Web development framework, Ruby on Rails.
Comprising forty-two selections from primary source materials, each translated with an introduction and commentary by a specialist in the field, this collection illustrates the religious cycles, rituals, and experiences that gave meaning to medieval Christian individuals and communities. The texts represent the practices through which Christians conducted their individual, family, and community lives and explore such life-cycle events as birth, confirmation, marriage, sickness, death, and burial. The texts also document religious practices related to themes of work, parish life, and devotions, as well as power and authority.--From publisher's description.
Still the only concise practical guide to laboratory experiments in proteomics, this new edition now also covers DIGE technology and liquid-chromatography, while the troubleshooting section has been considerably extended. Adopting a practical approach, the authors present the relevant techniques and explain the route to successful experimental design and optimal method selection. They cover such electrophoretic techniques as isoelectric focusing, SDS page, 2-D page, and DIGE, as well as liquid-chromatography techniques, such as ion exchange, affinity chromatography and reversed-phase HPLC. Mass-spectrometric techniques include MALDI, ESI, and FT ICR. Generously illustrated, partly in color, the book also features updates of protocols as well as animations illustrating crucial methodological steps on a companion website.
If you know basic high-school math, you can quickly learn and apply the core concepts of computer science with this concise, hands-on book. Led by a team of experts, you’ll quickly understand the difference between computer science and computer programming, and you’ll learn how algorithms help you solve computing problems. Each chapter builds on material introduced earlier in the book, so you can master one core building block before moving on to the next. You’ll explore fundamental topics such as loops, arrays, objects, and classes, using the easy-to-learn Ruby programming language. Then you’ll put everything together in the last chapter by programming a simple game of tic-tac-toe. Learn how to write algorithms to solve real-world problems Understand the basics of computer architecture Examine the basic tools of a programming language Explore sequential, conditional, and loop programming structures Understand how the array data structure organizes storage Use searching techniques and comparison-based sorting algorithms Learn about objects, including how to build your own Discover how objects can be created from other objects Manipulate files and use their data in your software

If you’re an experienced Ruby programmer, Effective Ruby will help you harness Ruby’s full power to write more robust, efficient, maintainable, and well-performing code. Drawing on nearly a decade of Ruby experience, Peter J. Jones brings together 48 Ruby best practices, expert tips, and shortcuts—all supported by realistic code examples. Jones offers practical advice for each major area of Ruby development, from modules to memory to metaprogramming. Throughout, he uncovers little-known idioms, quirks, pitfalls, and intricacies that powerfully impact code behavior and performance. Each item contains specific, actionable, clearly organized guidelines; careful advice; detailed technical arguments; and illuminating code examples. When multiple options exist, Jones shows you how to choose the one that will work best in your situation. Effective Ruby will help you systematically improve your code—not by blindly following rules, but by thoroughly understanding Ruby programming techniques. Key features of this concise guide include How to avoid pitfalls associated with Ruby’s sometimes surprising idiosyncrasies What you should know about inheritance hierarchies to successfully use Rails (and other large frameworks) How to use misunderstood methods to do amazingly useful things with collections Better ways to use exceptions to improve code reliability Powerful metaprogramming approaches (and techniques to avoid) Practical, efficient testing solutions, including MiniTest Unit and Spec Testing How to reliably manage RubyGem dependencies How to make the most of Ruby’s memory management and profiling tools How to improve code efficiency by understanding the Ruby interpreter’s internals
This book challenges this conventional wisdom that land claims and co-management -- two of the most visible and celebrated elements of this restructuring the relationship between Aboriginal peoples and the Canadian state -- will help reverse centuries of inequity. Based on three years of ethnographic research in the Yukon, the author examines the complex relationship between the people of Kluane First Nation, the land and animals, and the state. This book moves beyond conventional models of colonialism, in which the state is treated as a monolithic entity, and instead explores how "state power" is reproduced through everyday bureaucratic practices -- including struggles over the production and use of knowledge.
Expand your skills in the rapidly growing field of laser dentistry! Principles and Practice of Laser Dentistry uses a concise, evidence-based approach in describing protocols and procedures. Dr. Robert A. Convissar, a renowned lecturer on this subject, has assembled a diverse panel of international contributors; he’s also one of the first general dentists to use lasers in his practice. The book covers the history of lasers in dentistry and laser research, plus the use of lasers in periodontics, periodontal surgery, oral pathology, implantology, fixed and removable prosthetics, cosmetic procedures, endodontics, operative dentistry, pediatrics, orthodontics, and oral and maxillofacial surgery. Full-color images show the latest laser technology, surgical techniques, and key steps in patient treatment. Full-color photos and illustrations demonstrate surgical techniques and key teaching points. A Laser Fundamentals chapter describes the physics of lasers and the wavelengths that can produce better outcomes. Introducing Lasers into the Dental Practice chapter provides guidelines on investing in laser technology and in marketing this new procedure. Clinical Tip and Caution boxes include advice and alerts that can only be offered by a seasoned practitioner of 27 years.
