Book Description
The BISON code is the foundation for multiple fuel performance modeling efforts, and is currently under heavy development. For a variety of fuel forms, the effects of heat conduction across a gap and mechanical contact between components of a fuel system are very significant. It is thus critical that BISON have robust capabilities for enforcement of thermal and mechanical contact. BISON's solver robustness has generally been quite good before mechanical contact between the fuel and cladding occurs, but there have been significant challenges obtaining converged solutions once that contact occurs and the solver begins to enforce mechanical contact constraints. During the current year, significant development effort has been focused on the enforcement of mechanical contact to provide improved solution robustness. In addition to this work to improve mechanical contact robustness, an investigation into questionable results attributable to thermal contact has been performed. This investigation found that the order of integration typically used on the surfaces involved in thermal contact was not sufficiently high. To address this problem, a new option was provided to permit the use of a different integration order for surfaces, and new usage recommendations were provided.

Book Description
This summary report contains an overview of work performed under the work package entitled "FY2014 NEAMS INL-Engineering Scale Fuel Performance & Interface with RPL Tools." A first chapter identifies the specific FY-14 milestones, providing a basic description of the associated work and references to related detailed documentation. Where applicable, a representative technical result is provided. A second chapter summarizes substantial additional work including 1) efforts to improve numerical convergence and contact in BISON, 2) development of capability to simulate hydrogen behavior in Zircaloy cladding and 3) efforts to enhance collaborative work with the Halden Research Program. A final chapter briefly outlines planned future work.

Book Description
One of the great science and health revelations of our time is the danger posed by meat-eating. Every day, it seems, we are warned about the harm producing and consuming meat can do to the environment and our bodies. Many of us have tried to limit how much meat we consume, and many of us have tried to give it up altogether. But it is not easy to resist the smoky, cured, barbequed, and fried delights that tempt us. What makes us crave animal protein, and what makes it so hard to give up? And if consuming meat is truly unhealthy for human beings, why didn't't evolution turn us all into vegetarians in the first place? In Meathooked, science writer Marta Zaraska explores what she calls the "meat puzzle": our love of meat, despite its harmful effects. Zaraska takes us on a witty tour of meat cultures around the word, stopping in India's unusual steakhouses, animal sacrifices at temples in Benin, and labs in the Netherlands that grow meat in petri dishes. From the power of evolution to the influence of the meat lobby, and from our genetic makeup to the traditions of our foremothers, she reveals the interplay of forces that keep us hooked on animal protein. A book for everyone from the diehard carnivore to the committed vegan, Meathooked illuminates one of the most enduring features of human civilization, ultimately shedding light on why meat-eating will continue to shape our bodies -- and our world -- into the foreseeable future.

Book Description
The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.

Book Description
The Jefferson Bible, or The Life and Morals of Jesus of Nazareth as it is formally titled, was a book constructed by Thomas Jefferson in the latter years of his life by cutting and pasting numerous sections from various Bibles as extractions of the doctrine of Jesus. Jefferson's composition excluded sections of the New Testament containing supernatural aspects as well as perceived misinterpretations he believed had been added by the Four Evangelists. In 1895, the Smithsonian Institution under the leadership of librarian Cyrus Adler purchased the original Jefferson Bible from Jefferson's great-granddaughter Carolina Randolph for $400. A conservation effort commencing in 2009, in partnership with the museum's Political History department, allowed for a public unveiling in an exhibit open from November 11, 2011, through May 28, 2012, at the National Museum of American History.

Book Description
For over twenty years, Patagonia has organized a Tools Conference, where experts provide practical training to help make activists more effective. Now Patagonia has captured Tools’ best wisdom and advice into a book, creating a resource for any organization hoping to hone core skills like campaign and communication strategy, grassroots organizing, and lobbying as well as working with business, fundraising in uncertain times and using new technologies. Patagonia hopes the book will be dog-eared and scribbled in; a solid, inspiring guide and reliable companion. The book is organized in two sections: Strategies, and Tools. Each chapter, written by a respected expert in the field, covers essential principals as well as best practices. A hands-on case study accompanies each chapter and demonstrates the principles in action. Sprinkled throughout are inspirational thoughts from acclaimed activists, such as Jane Goodall, Bill McKibben, Wade Davis, Annie Leonard, and Terry Tempest Williams. An activist's companion in the environmental movement.
