    Lunar soil will potentially be used for oxygen generation, water generation, and as filler for building blocks during habitation missions on the Moon. NASA s in situ fabrication and repair program is evaluating portable technologies that can assess the chemistry of lunar soil and lunar soil simulants. This Technical Memorandum summarizes the results of the JSC 1 lunar soil simulant analysis using the TRACeR III IV handheld x-ray fluorescence analyzer, manufactured by KeyMaster Technologies, Inc. The focus of the evaluation was to determine how well the current instrument configuration would detect and quantify the components of JSC-1

    Condensed and Updated Version of the Systematic Approach Meteorological Knowledge Base Southern Hemisphere

    Get PDF
    The meteorological knowledge base for the Systematic and Integrated Approach to Tropical Cyclone Track Forecasting proposed by Carr and Elsberry has evolved as additional research has been completed. As this Systematic Approach has been applied in the Southern Hemisphere, a number of conceptual models have been refined and new terminology has been adopted to reflect global applicability. As a knowledge-based expert system is being developed, it was convenient to condense and update the meteorological knowledge base for the Southern Hemisphere. Thus, the material is presented with text on the left page and the corresponding figure on the facing page as it will appear on the computer screen.Prepared for: Office of Naval Research, Code 322MM, Arlington, VA 22217 SPAWARSYSCOM, Code PMW 185, San Diego, CA 92110http://archive.org/details/condensedupdated00carrSponsored by: Office of Naval Research and SPAWARSYSCOM.Approved for public release; distribution is unlimited

    Standardization of surface contamination analysis systems

    Get PDF
    Corrosion products, oils and greases can potentially degrade material bonding properties. The Marshall Space Flight Center (MSFC) Surface Contamination Analysis Team (SCAT) utilizes a variety of analytical equipment to detect identify and quantify contamination on metallic and non-metallic substrates. Analysis techniques include FT-IR Microscopy (FT-IR), Near Infrared Optical Fiber Spectrometry (NIR), Optically Stimulated Electron Emission (OSEE), Ultraviolet Fluorescence (UVF) and Ellipsometry. To insure that consistent qualitative and quantitative information are obtained, standards are required to develop analysis techniques, to establish instrument sensitivity to potential contaminants, and to develop calibration curves. This paper describes techniques for preparing and preserving contamination standards. Calibration of surface contamination analysis systems is discussed, and methods are presented for evaluating the effects of potential contaminants on bonding properties

    The Group Creativity Exercise Getting MBAs to Work and Think Effectively in Groups

    Get PDF
    This experiential exercise is designed to engage participants in a process of group creativity that helps students lead or be a part of a creative team. The challenging and tangible nature of building a room­height tower provides a heightened experience that elicits many issues and strong emotions. The exercise provides a robust platform from which the instructor can choose which of many group creativity subtopics to emphasize. In addition to exercise instructions, guidance is given on how learning goals related to creativity techniques, group development, interpersonal dynamics, and leadership—can be addressed in a debriefing discussion. Both “pre­taught” and “retrospective” teaching approaches are discussed, although a retrospective approach in which the instructor makes connections with theory during debriefing discussions is recommended. The experience of learning by doing should yield more realistic and memorable understanding of group creativity than could be accomplished with readings and/or lecture alone

    International Veterinary Epilepsy Task Force consensus proposal: Medical treatment of canine epilepsy in Europe

    Get PDF
    In Europe, the number of antiepileptic drugs (AEDs) licensed for dogs has grown considerably over the last years. Nevertheless, the same questions remain, which include, 1) when to start treatment, 2) which drug is best used initially, 3) which adjunctive AED can be advised if treatment with the initial drug is unsatisfactory, and 4) when treatment changes should be considered. In this consensus proposal, an overview is given on the aim of AED treatment, when to start long-term treatment in canine epilepsy and which veterinary AEDs are currently in use for dogs. The consensus proposal for drug treatment protocols, 1) is based on current published evidence-based literature, 2) considers the current legal framework of the cascade regulation for the prescription of veterinary drugs in Europe, and 3) reflects the authors’ experience. With this paper it is aimed to provide a consensus for the management of canine idiopathic epilepsy. Furthermore, for the management of structural epilepsy AEDs are inevitable in addition to treating the underlying cause, if possible

    Antiepileptic drugs’ tolerability and safety – a systematic review and meta-analysis of adverse effects in dogs

    Get PDF
    <p>Various anti-epileptic drugs (AEDs) are used for the management of idiopathic epilepsy (IE) in dogs. Their safety profile is an important consideration for regulatory bodies, owners and prescribing clinicians. However, information on their adverse effects still remains limited with most of it derived from non-blinded non-randomized uncontrolled trials and case reports.</p><p><span>This poster won third place, which was presented at the Veterinary Evidence Today conference, Edinburgh November 1-3, 2016. </span></p><br /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/oa-icon.jpg" alt="Open Access" /

    International Veterinary Epilepsy Task Force Consensus Proposal: Outcome of therapeutic interventions in canine and feline epilepsy

    Get PDF
    Common criteria for the diagnosis of drug resistance and the assessment of outcome are needed urgently as a prerequisite for standardized evaluation and reporting of individual therapeutic responses in canine epilepsy. Thus, we provide a proposal for the definition of drug resistance and partial therapeutic success in canine patients with epilepsy. This consensus statement also suggests a list of factors and aspects of outcome, which should be considered in addition to the impact on seizures. Moreover, these expert recommendations discuss criteria which determine the validity and informative value of a therapeutic trial in an individual patient and also suggest the application of individual outcome criteria. Agreement on common guidelines does not only render a basis for future optimization of individual patient management, but is also a presupposition for the design and implementation of clinical studies with highly standardized inclusion and exclusion criteria. Respective standardization will improve the comparability of findings from different studies and renders an improved basis for multicenter studies. Therefore, this proposal provides an in-depth discussion of the implications of outcome criteria for clinical studies. In particular ethical aspects and the different options for study design and application of individual patient-centered outcome criteria are considered
