This book was released on 2009 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World Distribution of Uranium Deposits (UDEPO) is a database on technical, geographical and geological characteristics of worldwide uranium deposits. Its purpose is to provide reliable and up-to-date information on the uranium deposits in the world. The UDEPO contains information on the location of deposits, the amount of uranium and average uranium grade in the deposits, geological type of the deposits, status of the deposits, operating organizations (if the deposit is being mined) and other technical and geological details about the deposits. It covers not only operational mines but also depleted or dormant deposits in order to provide an overview of past operations and future possibilities in addition to the existing uranium production information. This publication, with attached CD-ROM, is a snapshot of the database as of the end of 2008.--Publisher's description.

Download or read book Writing about Lives in Science written by Paola Govoni and published by V&R Unipress. This book was released on 2014-05-14 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following discussions on scientific biography carried out over the past few decades, this book proposes a kaleidoscopic survey of the uses of biography as a tool to understand science and its context. It offers food for thought on the role played by the gender of the biographer and the biographee in the process of writing. To provide orientation in such a challenging field, some of the authors have accepted to write about their own professional experience while reflecting on the case studies they have been working on. Focusing on (auto)biography may help us to build bridges between different approaches to men and women's lives in science. The authors belong to a variety of academic and professional fields, including the history of science, anthropology, literary studies, and science journalism. The period covered spans from 1732, when Laura Bassi was the first woman to get a tenured professorship of physics, to 2009, when Elizabeth H. Blackburn and Carol W. Greider were the first women's team to have won a Nobel Prize in science.

Download or read book Ice Tunnel Closure Phenomena written by John F. Abel and published by . This book was released on 1961 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanics of closure, exhibited by ice tunnels, can be understood by considering the ice as a viscous solid. The viscous solid will flow, when subjected to a force, at a rate dependent on the magnitude of the force, the area of relief open for flow, and the apparent viscosity of the viscous solid. In the case of the ice tunnels, the force inducing the flow is the weight of the overburden; the area of relief open for flow is the tunnel opening; and apparent viscosity is the resistance to flow exhibited by the ice. The closure of a rectangular opening made in ice was measured. Maximum closure occurs at the center of unsupported roof, wall, or floor spans. The vertical closure rate decreases negligibly approximately 2% from the center of a room to approximately 6 ft from the wall. From the point about 6 ft from the wall to the wall, the closure rate decreases about 30%. Approximately 30% of vertical closure at the center of the span is due to flexure of the floor and roof. The remaining 70% is due to shortening of the wall height; the major portion of this wall closure occurs at the bottom of the wall. Over 80% of closure due to flexure of the floor and roof results from flexure of the floor. (Author).

This book was released on 2010-06-14 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Download or read book Pest Risk Assessment of the Importation Into the United States of Unprocessed Eucalyptus Logs and Chips from South America written by and published by . This book was released on 2001 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, we assess the unmitigated pest risk potential of importing Eucalyptus logs and chips from South America into the United States. To do this, we estimated the likelihood and consequences of introducing representative insects and pathogens of concern. Nineteen individual pest risk assessments were prepared, eleven dealing with insects and eight with pathogens. The selected organisms were representative examples of insects and pathogens found on the foliage, on the bark, in the bark, and in the wood of Eucalyptus spp. Among the insects and pathogens assessed, eight were rated a high risk potential: purple moth (Sarsina violescens), scolytid bark and ambrosia beetles (Scolytopsis brasiliensis, Xyleborus retusus, Xyleborus biconicus, Xyleborus spp.), carpenterworm (Chilecomadia valdiviana) on Eucalyptus nitens, round-headed wood borers (Chydarteres striatus, Retrachyderes thoracicus, Trachyderes spp., Steirastoma breve, Stenodontes spinibarbis), eucalyptus longhorned borer (Phoracantha semipunctata), Botryosphaeria cankers (Botryosphaeria dothidea, Botryosphaeria obtusa, Botryosphaeria ribi), Ceratocystis canker (Ceratocystis fimbriata), and pink disease (Erythricium salmonicolor). A moderate pest risk potential was assigned to eleven other organisms or groups of organisms: eucalypt weevils (Gonipterus spp.), carpenterworm (Chilecomadia valdiviana) on two Eucalyptus species other than E. nitens, platypodid ambrosia beetle (Megaplatypus parasulcatus), yellow phorancantha borer (Phoracantha recurva), subterranean termites (Coptotermes spp., Heterotermes spp.), foliar diseases (Aulographina eucalypti, Cryptosporiopsis eucalypti, Cylindrocladium spp., Phaeophleospora spp., Mycosphaerella spp.), eucalyptus rust (Puccinia psidii), Cryphonectria canker (Cryphonectria cubensis), Cytospora cankers (Cytospora eucalypticola, Cytospora eucalyptina), Coniothyrium canker (Coniothyrium zuluense), and root and stem rots (Armillaria spp., Phellinus spp., Ganoderma sp., Gymnopilus spectabilis). For those organisms of concern that are associated with logs and chips of South American Eucalyptus spp., specific phytosanitary measures may be required to ensure the quarantine safety of proposed importations.
