Book Description
This book provides an overview of the latest advances concerning symbiotic relationships between plants and microbes, and their applications in plant productivity and agricultural sustainability. Symbiosis is a living phenomenon including dynamic variations in the genome, metabolism and signaling network, and adopting a multidirectional perspective on their interactions is required when studying symbiotic organisms. Although various plant-microbe symbiotic systems are covered in this book, it especially focuses on arbuscular mycorrhiza (AM) symbiosis and root nodule symbiosis, the two most prevalent systems. AM symbiosis involves the most extensive interaction between plants and microbes, in the context of phylogeny and ecology. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition, as well as the diversity of natural ecosystems, are frequently dependent upon the presence and activity of mycorrhizas. In turn, root nodule symbiosis includes morphogenesis and is formed by communication between plants and nitrogen-fixing bacteria. The biotechnological application of plant–microbe symbiosis is expected to foster the production of agricultural and horticultural products while maintaining ecologically and economically sustainable production systems. Designed as a hands-on guide, this book offers an essential resource for researchers and students in the areas of agri-biotechnology, soil biology and fungal biology.

Book Description
The SUPERMEN "After a rare speech at the National Center for Atmospheric Research in Boulder, Colorado, in 1976, programmers in the audience had suddenly fallen silent when Cray offered to answer questions. He stood there for several minutes, waiting for their queries, but none came. When he left, the head of NCAR's computing division chided the programmers. 'Why didn't someone raise a hand?' After a tense moment, one programmer replied, 'How do you talk to God?'" -from The SUPERMEN The Story of Seymour Cray and the Technical Wizards behind the Supercomputer "They were building revolutionary, not evolutionary, machines. . . . They were blazing a trail-molding science into a product. . . . The freedom to create was extraordinary." -from The Supermen In 1951, a soft-spoken, skinny young man fresh from the University of Minnesota took a job in an old glider factory in St. Paul. Computer technology would never be the same, for the glider factory was the home of Engineering Research Associates and the recent college grad was Seymour R. Cray. During his extraordinary career, Cray would be alternately hailed as "the Albert Einstein," "the Thomas Edison," and "the Evel Knievel" of supercomputing. At various times, he was all three-a master craftsman, inventor, and visionary whose disdain for the rigors of corporate life became legendary, and whose achievements remain unsurpassed. The Supermen is award-winning writer Charles J. Murray's exhilarating account of how the brilliant-some would say eccentric-Cray and his gifted colleagues blazed the trail that led to the Information Age. This is a thrilling, real-life scientific adventure, deftly capturing the daring, seat-of-the-pants spirit of the early days of computer development, as well as an audacious, modern-day David and Goliath battle, in which a group of maverick engineers beat out IBM to become the runaway industry leaders. Murray's briskly paced narrative begins during the final months of the Second World War, when men such as William Norris and Howard Engstrom began researching commercial applications for the code-breaking machines of wartime, and charts the rise of technological research in response to the Cold War. In those days computers were huge, cumbersome machines with names like Demon and Atlas. When Cray came on board, things quickly changed. Drawing on in-depth interviews-including the last interview Cray completed before his untimely and tragic death-Murray provides rare insight into Cray's often controversial approach to his work. Cray could spend exhausting hours in single-minded pursuit of a particular goal, and Murray takes us behind the scenes to witness late-night brainstorming sessions and miraculous eleventh-hour fixes. Cray's casual, often hostile attitude toward management, although alienating to some, was more than a passionate need for independence; he simply thought differently than others. Seymour Cray saw farther and faster, and trusted his vision with an unassailable confidence. Yet he inspired great loyalty as well, making it possible for his own start-up company, Cray Research, to bring the 54,000-employee conglomerate of Control Data to its knees. Ultimately, The Supermen is a story of genius, and how a unique set of circumstances-a small-team approach, corporate detachment, and a government-backed marketplace-enabled that genius to flourish. In an atmosphere of unparalleled freedom and creativity, Seymour Cray's vision and drive fueled a technological revolution from which America would emerge as the world's leader in supercomputing.

Book Description
For a one-semester undergraduate course in operating systems for computer science, computer engineering, and electrical engineering majors. Winner of the 2009 Textbook Excellence Award from the Text and Academic Authors Association (TAA)! Operating Systems: Internals and Design Principles is a comprehensive and unified introduction to operating systems. By using several innovative tools, Stallings makes it possible to understand critical core concepts that can be fundamentally challenging. The new edition includes the implementation of web based animations to aid visual learners. At key points in the book, students are directed to view an animation and then are provided with assignments to alter the animation input and analyze the results. The concepts are then enhanced and supported by end-of-chapter case studies of UNIX, Linux and Windows Vista. These provide students with a solid understanding of the key mechanisms of modern operating systems and the types of design tradeoffs and decisions involved in OS design. Because they are embedded into the text as end of chapter material, students are able to apply them right at the point of discussion. This approach is equally useful as a basic reference and as an up-to-date survey of the state of the art.

Book Description
Are you an SQL programmer that, like many, came to SQL after learning and writing procedural or object-oriented code? Or have switched jobs to where a different brand of SQL is being used, or maybe even been told to learn SQL yourself? If even one answer is yes, then you need this book. A "Manual of Style" for the SQL programmer, this book is a collection of heuristics and rules, tips, and tricks that will help you improve SQL programming style and proficiency, and for formatting and writing portable, readable, maintainable SQL code. Based on many years of experience consulting in SQL shops, and gathering questions and resolving his students' SQL style issues, Joe Celko can help you become an even better SQL programmer. - Help you write Standard SQL without an accent or a dialect that is used in another programming language or a specific flavor of SQL, code that can be maintained and used by other people. - Enable you to give your group a coding standard for internal use, to enable programmers to use a consistent style. - Give you the mental tools to approach a new problem with SQL as your tool, rather than another programming language — one that someone else might not know!
