    Action Plan to Follow-up on UNCED: Report of the CGIAR Task Force

    Get PDF
    Report of a task force assigned to formulate a CGIAR response to UNCED's Agenda 21, and the conventions on biological diversity, climate change, and desertification that were now emerging from it. The task force prescribed four CGIAR global initiatives: Marginal Soils, Genetic Resources, Human Resources, and a joint effort with the UNEP to develop a geographic information system (GIS) and agroecological database. It was proposed that all four initiatives be financed by a UNEP trust fund administered by a steering committee comprised of CGIAR and non-CGIAR representatives, with a full time facilitator.Appendixes are a detailed proposal for the GIS, and terms of reference for the proposed trust fund.Agenda document at TAC 62 and CGIAR International Centers Week, October 1993

    Imaging follow-up after liver transplantation

    Get PDF
    Liver transplantation (LT) represents the best treatment for end-stage chronic liver disease, acute liver failure and early stages of hepatocellular carcinoma. Radiologists should be aware of surgical techniques to distinguish a normal appearance from pathological findings. Imaging modalities, such as ultrasound, CT and MR, provide for rapid and reliable detection of vascular and biliary complications after LT. The role of imaging in the evaluation of rejection and primary graft dysfunction is less defined. This article illustrates the main surgical anastomoses during LT, the normal appearance and complications of the liver parenchyma and vascular and biliary structures.Liver transplantation (LT) represents the best treatment for end-stage chronic liver disease, acute liver failure and early stages of hepatocellular carcinoma.

    Surveys, Astrometric Follow-up & Population Statistics

    Asteroid surveys are the backbone of asteroid science, and with this in mind we begin with a broad review of the impact of asteroid surveys on our field. We then provide a brief history of asteroid discoveries so as to place contemporary and future surveys in perspective. Surveys in the United States have discovered the vast majority of the asteroids and this dominance has been consolidated since the publication of Asteroids III. Our descriptions of the asteroid surveys that have been operational since that time are focussed upon those that have contributed the vast majority of asteroid observations and discoveries. We also provide some insight into upcoming next-generation surveys that are sure to alter our understanding of the small bodies in the inner solar system and provide evidence to untangle their complicated dynamical and physical histories. The Minor Planet Center, the nerve center of the asteroid discovery effort, has improved its operations significantly in the past decade so that it can manage the increasing discovery rate, and ensure that it is well-placed to handle the data rates expected in the next decade. We also consider the difficulties associated with astrometric follow-up of newly identified objects. It seems clear that both of these efforts must operate in new modes in order to keep pace with expected discovery rates of next-generation ground- and space-based surveys.Comment: Chapter to appear in the book ASTEROIDS IV, (University of Arizona Press) Space Science Series, edited by P. Michel, F. DeMeo and W. Bottk

    The Kepler Follow-up Observation Program

    Full text link
    The Kepler Mission was launched on March 6, 2009 to perform a photometric survey of more than 100,000 dwarf stars to search for terrestrial-size planets with the transit technique. Follow-up observations of planetary candidates identified by detection of transit-like events are needed both for identification of astrophysical phenomena that mimic planetary transits and for characterization of the true planets and planetary systems found by Kepler. We have developed techniques and protocols for detection of false planetary transits and are currently conducting observations on 177 Kepler targets that have been selected for follow-up. A preliminary estimate indicates that between 24% and 62% of planetary candidates selected for follow-up will turn out to be true planets.Comment: 12 pages, submitted to the Astrophysical Journal Letter

    Do a follow-up lunchroom waste characterization (post waste-free lunch day or policy implementation)

    Get PDF
    The baseline waste characterization helped you identify and quantify waste streams in your facility. The initial waste characterization enabled you to create a tailored strategy for your facility to reduce food waste. A follow-up waste characterization provides an objective tool to measure progress as you implement your strategy.Funded by U.S. Environmental Protection Agency Region 5Ope

    As a follow-up to CERN's New "Information for World Transformation" ? appeared in 2012 Daily, we report here that there are scientists who have provided alternative explanations to the apparent faster-than-light neutrino speed reported by CERN and there are also scientists who are claiming victories over OPERA results supporting their theories
