Скачать книгу - Precambrian Sedimentary Environments
The motivation for this volume came from the idea that the Precambrian is the key, both to the present, and to the understanding of the Earth as a whole. The Precambrian constitutes about 85% of Earth's history, and of that, about 3.75 billion years of Precambrian time, represented by rocks, are accessible to geoscientists. Ancient atmospheric and environmental conditions can be traced back to the time when the Earth was only about 250 million years old. Precambrian rocks supply almost 75% of important mineral resources such as Fe, Mn, Au, Pt and Cr. Many of these elements are associated with sedimentary rocks and some important hydrocarbon, coal and graphite deposits are also hosted by Precambrian rocks. This volume is aimed at geoscientists interested in Precambrian sedimentary rocks and at students of Earth history. It contains review articles discussing Precambrian conditions and case studies from Precambrian shields and successions of North and South America, Australia, Africa, Europe, Asia and India. The introductory papers, written by experts on Precambrian environments, treat comprehensively the application of actualism to the Precambrian, the evolution and influence of life on the sedimentary rock record, the genesis of Banded Iron Formations, the Precambrian sulphur cycle and the significance of Precambrian chemical carbonate precipitates. The case studies include depositional settings and processes in Archean terranes, in Paleoproterozoic sequences, with some emphasis on the lack of vegetation and weathering, and in late Proterozoic sequences, with some emphasis on glacial deposits. The contributions demonstrate that Precambrian sedimentary deposits are commonly similar to their Phanerozoic counterparts in terms of composition, sedimentary processes, and depositional setting, but may differ significantly as a result of lack of vegetation, climatic and biological constraints, composition and circulation of seawater, and the secular involvement of continental crust.

From the Campfire to the Holodeck. Creating Engaging and Powerful 21st Century Learning Environments From the Campfire to the Holodeck. Creating Engaging and Powerful 21st Century Learning Environments

Автор: David Thornburg

Год издания: 

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).

Virtualization Security. Protecting Virtualized Environments Virtualization Security. Protecting Virtualized Environments

Автор: Dave Shackleford

Год издания: 

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.


Sedimentology and Sedimentary Basins. From Turbulence to Tectonics Sedimentology and Sedimentary Basins. From Turbulence to Tectonics

Автор: Mike Leeder R.

Год издания: 

The sedimentary record on Earth stretches back more than 4.3 billion years and is present in more abbreviated forms on companion planets of the Solar System, like Mars and Venus, and doubtless elsewhere. Reading such planetary archives correctly requires intimate knowledge of modern sedimentary processes acting within the framework provided by tectonics, climate and sea or lake level variations. The subject of sedimentology thus encompasses the origins, transport and deposition of mineral sediment on planetary surfaces. The author addresses the principles of the subject from the viewpoint of modern processes, emphasising a general science narrative approach in the main text, with quantitative background derived in enabling ‘cookie’ appendices. The book ends with an innovative chapter dealing with how sedimentology is currently informing a variety of cognate disciplines, from the timing and extent tectonic uplift to variations in palaeoclimate. Each chapter concludes with a detailed guide to key further reading leading to a large bibliography of over 2500 entries. The book is designed to reach an audience of senior undergraduate and graduate students and interested academic and industry professionals.
