Найти книгу: "Antarctic Subglacial Aquatic Environments"

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 192. Antarctic Subglacial Aquatic Environments is the first volume on this important and fascinating subject. With its underlying theme of bridging existing knowledge to future research, it is a benchmark in the history of subglacial lake exploration and study, containing up-to-date discussions about the history and background of subglacial aquatic environments and future exploration. The main topics addressed are identification, location, physiography, and hydrology of 387 subglacial lakes; protocols for environmental stewardship and protection of subglacial lake environments; details of three programs aiming to explore Vostok Subglacial Lake, Ellsworth Subglacial Lake, and Whillans Subglacial Lake over the next 3–5 years; assessment of technological requirements for exploration programs based on best practices for environmental stewardship and scientific success; and knowledge of subglacial lakes as habitats for microbial life and as recorders of past climate and ice sheet change. Its uniqueness, breadth, and inclusiveness will appeal to microbiologists and those interested in life in extreme environments, paleoclimatologists and those interested in sedimentary records of past changes, glaciologists striving to understand how water beneath glaciers affects their flow, and those engaged in developing technology to undertake direct measurement and sampling of extreme environments on Earth and in the solar system.

How to optimize educational spaces and teaching practices for more effective learning Author David Thornburg, an award-winning futurist and educational consultant, maintains that in order to engage all students, learning institutions should offer a balance of Campfire spaces (home of the lecture), Watering Holes (home to conversations between peers), Caves (places for quiet reflection), and Life (places where students can apply what they've learned). In order to effectively use technology in the classroom, prepare students for future careers, and incorporate project-based learning, all teachers should be moving from acting as the «sage on the stage» to becoming the «guide on the side.» Whether you are a school administrator interested in redesigning your school or a teacher who wants to prepare better lessons, From the Campfire to the Holodeck can help by providing insight on how to: Boost student engagement Enable project-based learning Incorporate technology into the classroom Encourage student-led learning From the Campfire to the Holodeck is designed to help schools move from traditional lecture halls (Campfires) where students just receive information to schools that encourage immersive student-centered learning experiences (Holodecks).

How to apply digital writing skills effectively in the classroom, from the prestigious National Writing Project As many teachers know, students may be adept at text messaging and communicating online but do not know how to craft a basic essay. In the classroom, students are increasingly required to create web-based or multi-media productions that also include writing. Since writing in and for the online realm often defies standard writing conventions, this book defines digital writing and examines how best to integrate new technologies into writing instruction. Shows how to integrate new technologies into classroom lessons Addresses the proliferation of writing in the digital age Offers a guide for improving students' online writing skills The book is an important manual for understanding this new frontier of writing for teachers, school leaders, university faculty, and teacher educators.

Use Maya to create realistic environments and props for digital games Weapons, vehicles, tools, buildings, trees, plants, walls, ceilings, and floors-these items may seem secondary to the game environment, but they are integral parts of the game and they all need to be created. Maya Studio Projects: Game Environments and Props is a step-by-step project guide to creating some of the most popular game art. Author Michael McKinley shares techniques for getting the most out of Maya to create realistic, vivid, and compelling worlds and otherworldly props. Along the way, he provides notes and FYIs that give readers depth and breadth for bringing both reality and creativity to their game art. A bonus DVD features step-by-step videos to help drive home concepts. The Studio Projects series offers projects that start from nothing, just as they do in the studio; these books provide you with a step-by-step guide to software attributes and tools that encompass multiple disciplines so that you can create a finished, renderable object Many games have only a few characters, and multiple levels and environments, and hundreds of props-this book focuses on projects and techniques for creating everything but the character Maya is the top 3D app for creating console and computer games such as: Rock Band, Gears of War, James Bond: Quantum of Solace, Fallout 3, and Far Cry 2 Learn effective Maya studio techniques with this handy, step-by-step, full-color book. Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.

Securing virtual environments for VMware, Citrix, and Microsoft hypervisors Virtualization changes the playing field when it comes to security. There are new attack vectors, new operational patterns and complexity, and changes in IT architecture and deployment life cycles. What's more, the technologies, best practices, and strategies used for securing physical environments do not provide sufficient protection for virtual environments. This book includes step-by-step configurations for the security controls that come with the three leading hypervisor–VMware vSphere and ESXi, Microsoft Hyper-V on Windows Server 2008, and Citrix XenServer. Includes strategy for securely implementing network policies and integrating virtual networks into the existing physical infrastructure Discusses vSphere and Hyper-V native virtual switches as well as the Cisco Nexus 1000v and Open vSwitch switches Offers effective practices for securing virtual machines without creating additional operational overhead for administrators Contains methods for integrating virtualization into existing workflows and creating new policies and processes for change and configuration management so that virtualization can help make these critical operations processes more effective This must-have resource offers tips and tricks for improving disaster recovery and business continuity, security-specific scripts, and examples of how Virtual Desktop Infrastructure benefits security.

Droughts are a major hazard to both natural and human-dominated environments and those, especially of long duration and high intensity, can be highly damaging and leave long-lasting effects. This book describes the climatic conditions that give rise to droughts, and their various forms and chief attributes. Past droughts are described including those that had severe impacts on human societies. As a disturbance, droughts can be thought of as “ramps” in that they usually build slowly and take time to become evident. As precipitation is reduced, flows from catchments into aquatic systems decline. As water declines in water bodies, ecological processes are changed and the biota can be drastically reduced, though species and populations may survive by using refuges. Recovery from drought varies in both rates and in degrees of completeness and may be a function of both refuge availability and connectivity. For the first time, this book reviews the available rather scattered literature on the impacts of drought on the flora, fauna and ecological processes of aquatic ecosystems ranging from small ponds to lakes and from streams to estuaries. The effects of drought on the biota of standing waters and flowing waters and of temporary waters and perennial systems are described and compared. In addition, the ways in which human activity can exacerbate droughts are outlined. In many parts of the world especially in the mid latitudes, global warming may result in increases in the duration and intensity of droughts. Drought and Aquatic Ecosystems is essential reading for freshwater ecologists, water resource managers and advanced students.
