    The Ascension Factor: The Pandora Sequence, Book 3 , Hörbuch, Digital, ungekürzt, 849min
    Set 25 years after The Lazarus Effect, this final book in the Destination: Void collaboration between Frank Herbert and Bill Ransom concludes the story of the planet Pandora. Pandora's humans have been recovering land from its raging seas at an accelerated pace since The Lazarus Effect. The great kelp of the seas, sentient but electronically manipulated by humans, buffers Pandora's wild currents to restore land and facilitate the booming sea trade. New settlements rise overnight, but children starve in their shadows. An orbiting assembly station is near completion of Project Voidship, which is the hope of many for finding a better world. Pandora is under the fist of an ambitious clone from hibernation called the Director, who rules with a sadistic security force led by the assassin Spider Nevi. Small resistance groups have had little effect on his absolute power. The Director controls the transportation of foodstuffs; uprisings are punished with starvation. The resistance fighters' main hope is Crista Galli, a woman believed by some to be the child of God. Crista pools her talents with Dwarf MacIntosh, Beatriz Tatoosh, and Rico LaPush to transcend the barriers between the different species and overthrow the Director and the sinister cabal with which he rules. ungekürzt.

    Authentic Happiness: Using the New Positive Psychology to Realize Your Potential for Lasting Fulfillment, Hörbuch, Digital, 265min
    Over a decade ago, Martin Seligman charted a new approach to living with "flexible optimism". Now, in his most stimulating and persuasive book to date, the best-selling author of Learned Optimism introduces the revolutionary, scientifically based idea of "Positive Psychology". Positive Psychology focuses on strengths rather than weaknesses, asserting that happiness is not the result of good genes or luck. Seligman teaches readers that happiness can be cultivated by identifying and using many of the strengths and traits that they already possess: kindness, originality, humor, optimism, and generosity. By frequently calling upon their "signature strengths" in all the crucial realms of life, listeners will not only develop natural buffers against misfortune and the experience of negative emotion, they will move their lives up to a new, more positive plane. Drawing on groundbreaking psychological research, Seligman shows how Positive Psychology is shifting the profession's paradigm away from its narrow-minded focus on pathology, victimology, and mental illness to positive emotion, virtue and strength, and positive institutions. Our signature strengths can be nurtured throughout our lives, with benefits to our health, relationships, and careers. The life-changing lesson of Authentic Happiness is that by identifying the very best in ourselves, we can improve the world around us and achieve new and sustainable levels of authentic contentment, gratification, and meaning.

    ABG Interpretation for Nurses: Everything You Need to Know to Interpret Arterial Blood Gases (Resources for RNs & RRTs, Book 1) , Hörbuch, Digital, ungekürzt, 201min
    Great Resource for Nurses, MDs, and RRTsArterial blood gases (or ABGs) are some of the more difficult lab tests to understand in all of medicine. Sure, there are normal results given along with the test values, but it doesn't end there. What does a certain pH in the blood mean? Where does the bicarbonate level come from? These components, along with other values, need to be understood so you can interpret them. Basically, the ABGs are a test of the arterial blood that check the oxygen levels, the carbon dioxide levels, the acidity (or pH) of the blood, the oxyhemoglobin saturation, and the bicarbonate. If you have a fancy blood gas analyzer, you can get a methemoglobin level, a carboxyhemoglobin level, and sometimes just a hemoglobin level. Each of these lab tests reveal crucial values that are important in caring for patients in the intensive care unit (ICU) and other hospital settings. If you do not know what oxyhemoglobin saturation means (or any of these values), never fear! By the time you finish this guide, you will be an old pro! In this book, you will learn:  The Science of Arterial Blood GasespH, Buffers, and the Kidneys Normal ABG ValuesSimple Acid-Base Disorders Deep dive into Understanding ABGs in the Clinical Sense ABG Collection and Sources of Error Helpful Study Tools We RecommendPractice Questions / Case StudiesGet yours today by scrolling up and ordering now! ungekürzt.

    Protein Analysis and Purification
    How one goes about analyzing proteins is a constantly evolving ?eld that is no longer solely the domain of the protein biochemist. Inves- gators from diverse disciplines ?nd themselves with the unanticipated task of identifying and analyzing a protein and studying its physical properties and biochemical interactions. In most cases, the ultimate goal remains understanding the role(s) that the target protein is playing in cellular physiology. It was my intention that this manual would make the initial steps in the discovery process less time consuming and less intimidating. This book is not meant to be read from cover to cover. The expanded Table of Contents and the index should help locate what you are seeking. My aim was to provide practically oriented information that will assist the experimentalist in benchtop problem solving. The appendices are ?lled with diverse information gleaned from catalogs, handbooks, and manuals that are presented in a distilled fashion designed to save trips to the library and calls to technical service representatives. The user is encouraged to expand on the tables and charts to ?t individual experimental situations. This second edition pays homage to the computer explosion and the various genome projects that have revolutionized how benchtop scienti?c research is performed. Bioinformatics and In silico science are here to stay. However, the second edition still includes recipes for preparing buffers and methods for lysing cells.

    Hacking: The Art of Exploitation, 2nd Edition (eBook, ePUB)
    Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker's perspective. The included LiveCD provides a complete Linux programming and debugging environment—all without modifying your current operating system. Use it to follow along with the book's examples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network communications, bypassing protections, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to: - Program computers using C, assembly language, and shell scripts - Corrupt system memory to run arbitrary code using buffer overflows and format strings - Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening - Outsmart common security measures like nonexecutable stacks and intrusion detection systems - Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presence - Redirect network traffic, conceal open ports, and hijack TCP connections - Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix Hackers are always pushing the boundaries, investigating the unknown, and evolving their art. Even if you don't already know how to program, Hacking: The Art of Exploitation, 2nd Edition will give you a complete picture of programming, machine architecture, network communications, and existing hacking techniques. Combine this knowledge with the included Linux environment, and all you need is your own creativity.

    Agile Estimating and Planning
    The first step to project success is accurate estimating and realistic planning. Projects with unrealistic expectations affixed to them are likely to derail at an early stage. This book shows the software practitioner how to effectively estimate and properly plan a project within an agile context. The book's content is suitable for projects using any agile or semi-agile process (such as Extreme Programming, Scrum, Feature Driven Development, Crystal, Adaptive Software Development, DSDM or even the IBM Rational Unified Process). The ideas in this book will work with any iterative development process, which greatly broadens the target audience beyond the traditional agile community. Each chapter is supported by a summary and a set of questions that allows readers to assess their ability to estimate and plan a project. The result is an engaging read with pearls of wisdom that can be applied to the reader's next project. Product Description Praise for Agile Estimating and Planning Traditional, deterministic approaches to planning and estimating simply don't cut it on the slippery slopes of today's dynamic, change-driven projects. Mike Cohn's breakthrough book gives us not only the philosophy, but also the guidelines and a proven set of tools that we need to succeed in planning, estimating, and scheduling projects with a high uncertainty factor. At the same time, the author never loses sight of the need to deliver business value to the customer each step of the way. -Doug DeCarlo, author of eXtreme Project Management: Using Leadership, Principles and Tools to Deliver Value in the Face of Volatility (Jossey-Bass, 2004) We know how to build predictive plans and manage them. But building plans that only estimate the future and then embrace change, challenge most of our training and skills. In Agile Estimating and Planning, Mike Cohn once again fills a hole in the Agile practices, this time by showing us a workable approach to Agile estimating and planning. Mike delves into the nooks and crannies of the subject and anticipates many of the questions and nuances of this topic. Students of Agile processes will recognize that this book is truly about agility, bridging many of the practices between Scrum and ExtremeProgramming. -Ken Schwaber, Scrum evangelist, Agile Alliance cofounder, and signatory to the Agile Manifesto In Agile Estimating and Planning, Mike Cohn has, for the first time, brought together most everything that the Agile community has learned about the subject. The book is clear, well organized, and a pleasant and valuable read. It goes into all the necessary detail, and at the same time keeps the reader's burden low. We can dig in as deeply as we need to, without too much detail before we need it. The book really brings together everything we have learned about Agile estimation and planning over the past decade. It will serve its readers well. -Ron Jeffries, www.XProgramming.com, author of Extreme Programming Installed (Addison-Wesley, 2001) and Extreme Programming Adventures in C# (Microsoft Press, 2004) Agile Estimating and Planning provides a view of planning that's balanced between theory and practice, and it is supported by enough concrete experiences to lend it credibility. I particularly like the quote 'planning is a quest for value.' It points to a new, more positive attitude toward planning that goes beyond the 'necessary evil' view that I sometimes hold. -Kent Beck, author of Extreme Programming Explained, Second Edition (Addison-Wesley, 2005) Up-front planning is still the most critical part of software development. Agile software development requires Agile planning techniques. This book shows you how to employ Agile planning in a succinct, practical, and easy-to-follow manner. -Adam Rogers, Ultimate Software Mike does a great follow-up to User Stories Applied by continuing to provide Agile teams with the practical approaches and techniques to increase agility. In this book, Mike provides time-proven and well-tested methods for being successful with the multiple levels of planning and estimating required by Agile. This book is the first to detail the disciplines of Agile estimating and planning, in ways that rival my 1980 civil engineering texts on CPM Planning and Estimating. -Ryan Martens, President and Founder, Rally Software Development Corporation With insight and clarity, Mike Cohn shows how to effectively produce software of high business value. With Agile estimation and planning, you focus effort where it really counts, and continue to do so as circumstances change. -Rick Mugridge, Rimu Research Ltd., and lead author, Fit for Developing Software (Prentice Hall, 2005) Finally! The groundbreaking book my clients have been clamoring for! Agile Estimating and Planning demystifies the process of defining, driving, and delivering great software that matters to the business. Mike's clarity, insight, and experience leap out through every page of this book, offering an approach that is relevant and immediately useful to all members of an Agile project. -Kert D. Peterson, President, Enterprise Agile Group, LLC This isn't yet another generic book on Agile software development. Agile Estimating and Planning fills a gap left by most of the other books and gives you important, practical, down-to-earth techniques needed to be successful on Agile development projects. -Steve Tockey, Principal Consultant, Construx Software Estimation, planning, and tracking is a trinity. If you don't do one of them, you don't need the other two. This book provides very practical knowledge for estimation, planning, prioritizing, and tracking. It should be compulsory subject matter for project managers and their teams, even if they hesitate to call themselves Agile. -Niels Malotaux, Project Coach Effective planning is an important, but often misunderstood, part of any successful Agile project. With Agile Estimating and Planning, Mike Cohn has given us a definitive guide to a wide range of Agile estimating and planning practices. With his clear and practical style, Mike not only explains how to successfully get started planning an Agile project, but also provides a wealth of tips and advice for improving any team's Agile planning process. This book is a must-read for managers, coaches, and members of Agile teams. -Paul Hodgetts, Agile coach and CEO, Agile Logic Mike's writing style captures the essence of agility-just the right amount of information to bring clarity to the reader. This book provides an excellent guide for all Agile practitioners, both seasoned and novice. -Robert Holler, President and CEO, VersionOne, LLC It is as if Mike took the distilled knowledge regarding planning and estimation of a great Agile developer (which he is) and laid out all he knows in an easily understandable manner. More importantly, he has a great mix of concepts with real-world examples finished off with a case study so the reader can relate the information to their own situation. Unless you are already an expert Agile planner and estimator, this book is for you. -Alan Shalloway, CEO, Senior Consultant, Net Objectives, and coauthor of Design Patterns Explained, Second Edition (Addison-Wesley, 2005) Although I had plenty of XP experience before trying out Mike Cohn's Agile planning practices, the effectiveness of the practical and proven techniques in this book blew me away! The book recognizes that people, not tools or processes, produce great software, and that teams benefit most by learning about their project and their product as they go. The examples in the book are concrete, easily grasped, and simply reek of common sense. This book will help teams (whether Agile or not) deliver more value, more often, and have fun doing it! Whether you're a manager or a programmer, a tester or a CEO, part of an Agile team, or just looking for a way to stamp out chaos and death marches, this book will guide you. -Lisa Crispin, coauthor of Testing Extreme Programming (Addison-Wesley, 2003) Mike Cohn does an excellent job demonstrating how an Agile approach can address issues of risk and uncertainty in order to provide more meaningful estimates and plans for software projects. -Todd Little, Senior Development Manager, Landmark Graphics Mike Cohn explains his approach to Agile planning, and shows how 'critical chain' thinking can be used to effectively buffer both schedule and features. As with User Stories Applied, this book is easy to read and grounded in real-world experience. -Bill Wake, author o Features + Benefits Goes beyond the strategy of just enough planning and estimating, and shows readers how to make agile practices truly work organizationally. ° Save time, conserve organizational resources, and manage software projects more efficiently by learning to anticipate future needs ° Key points are supported by case studies derived from real-world projects ° Teaches the nuts and bolts of estimating a project, an iteration, or even a task -- and teaches a variety of approaches to effective estimating Backcover Praise for Agile Estimating and Planning Traditional, deterministic approaches to planning and estimating simply don't cut it on the slippery slopes of today's dynamic, change-driven projects.
