The updated 2020 NASA Technology Taxonomy, or "technology dictionary", uses a technology discipline based approach that realigns like-technologies independent of their application within the NASA mission portfolio. This tool is meant to serve as a common technology discipline-based communication tool across the agency and with its partners in other government agencies, academia, industry, and across the world

    cereus Fun: An Introduction to Microbiological Techniques

    Get PDF
    Microbiology is a field of science devoted to the study of organisms that are too small to see; therefore, an engaging laboratory experience is often the key to capturing students\u27 interest. It was with this in mind that this book was first conceived and developed. The goal was to provide undergraduate microbiology students with an engaging and meaningful laboratory experience that nurtured a sense of discovery and encouraged greater interest in microbiology as a topic, a field of study, or a career. This lab manual – which has been field-tested by hundreds of microbiology students over several years – builds skills while reinforcing core microbiology concepts introduced in lectures. The curriculum builds from the ground up. It begins with an introduction to biosafety practices and work with biological hazards, basic but essential microscopy skills, and aseptic technique and culture methods, and then it builds to include more advanced methods. The progression includes a semester-long investigation of a bacterial isolate and culminates with a practical evaluation of all of the microbiology skills learned in the course

    Nonlethal Weapons: Terms and References

    Get PDF
    The purpose of this paper is to promote an understanding of and research into a new category of weapons, designated nonlethal by military services, and less than lethal or less lethal by law enforcement agencies. The intent is to create an initial term and reference listing to help support joint force and dual use initiatives focused on identifying the potential drawbacks of integrating nonlethal weapons into our military services and law enforcement agencies. The paper is split into two sections: a list of terms that describes nonlethal weapons along with the concepts both surrounding and inhibiting their use, and a comprehensive listing of references to facilitate further research. Nonlethal weapons are listed under the categories of acoustics, opticals, antilethals, antiplant agents, barriers, batons, biotechnicals, electricals, electromagnetics, entanglers, holograins, markers, obscurants, projectiles, reactants, and riot control agents. Nonlethal weapons concepts are divided by the following categories: ethical, functional, operational, physiological, and theoretical

    Fuel Conservation by the Application of Spill Prevention and Failsafe Engineering (A Guideline Manual)

    Full text link
    From a series of nationwide plant surveys dedicated to spill prevention, containment and countermeasure evaluation, coupled with spill response action activities, a need was determined for a spill prevention guideline manual. From Federally accumulated statistics for oil and hazardous substance spills, the authors culled information on spills of hydrocarbon products. In 1978, a total of 1456 oil spills were reported compared to 1451 in 1979. The 1978 spills were more severe, however, since 7;289,163 gallons of oil were accident~y discharged. In 1979, the gallons spilled was reduced to 3,663,473. These figures are derived from reported spills; it is highly possible that an equal amount was spilled and not reported. Spills effectively contained within a plant property that do not enter a n~vigational waterway need not be reported. Needless to say, there is a tremendous annual loss of oil products due to accidental spillage during transportation, cargo transfer, bulk storage and processing. As an aid to plant engineers and managers, Fe~eral workers, fire marshalls and fire and casualty insurance inspectors, the documen~ is offered as a spill prevention guide. The'manual defines state-of-the-art spill prevention practices and automation techniques that can reduce spills caused by human error. Whenever practical, the cost of implementation is provided to aid equipment acquisition and installation budgeting. To emphasize the need for spill prevention activities, historic spills are briefly described after which remedial action is defined in an appropriate section of the manual. The section on plant security goes into considerable depth since to date no Federal agency or traqe association has provided industry with guidelines on this important phase of plant operation. The intent of the document is to provide finger-tip reference material that can be used by interested parties in a nationwide effort to reduce loss of oil from preventable spills

    Weed Control Methods Handbook: Tools & Techniques for Use in Natural Areas

    Get PDF
    Invasive non-native plants are a serious threat to native species, communities, and ecosystems in many areas around the world. They can compete with and displace native plants, animals, and other organisms that depend on them, alter ecosystem functions and cycles significantly, hybridize with native species, and promote other invaders. The good news is that many plant invasions can be reversed, halted or slowed, and in certain situations, even badly infested areas can be restored to healthy systems dominated by native species. In most instances this requires taking action to control and manage those invasive plants. This handbook provides you with detailed information about the tools and techniques available for controlling invasive plants, or weeds, in natural areas. Whenever possible, language familiar to natural area managers is used, and unfamiliar terms and jargon borrowed from other fields are defined. Before embarking on a weed management program, it is important to develop a straightforward rationale for the actions you plan to take. We believe this is best accomplished using an adaptive management approach as follows (see Figure 1): (1) establish management goals and objectives for the site; (2) determine which plant species or populations, if any, block or have potential to block attainment of the management goals and objectives; (3) determine which methods are available to control the weed(s); (4) develop and implement a management plan designed to move conditions toward management goals and objectives; (5) monitor and assess the impacts of management actions in terms of their effectiveness in moving conditions toward these goals and objectives; and (6) reevaluate, modify, and start the cycle again. Note that control activities are not begun until the first three steps have been taken. A weed control program is best viewed as part of an overall restoration program, so focus on what you want in place of the weed, rather than simply eliminating the weed. When selecting control methods, keep in mind that the ultimate purpose of the work is to preserve native species, communities, and/or functioning ecosystems

    Bringing the Future Within Reach: Celebrating 75 Years of the NASA John H. Glenn Research Center

    Get PDF
    The National Aeronautics and Space Administration (NASA) Glenn Research Center in Cleveland, Ohio, has been making the future for 75 years. The center's work with aircraft engines, high-energy fuels, communications technology, electric propulsion, energy conversion and storage, and materials and structures has been, and continues to be, crucial to both the Agency and the region. Glenn has partnered with industry, universities, and other agencies to continually advance technologies that are propelling the nation's aerospace community into the future. Nonetheless these continued accomplishments would not be possible without the legacy of our first three decades of research, which led to over one hundred R&D 100 Awards, three Robert J. Collier Trophies, and an Emmy. Glenn, which is located in Cleveland, Ohio, is 1 of 10 NASA field centers, and 1 of only 3 that stem from an earlier research organization-the National Advisory Committee for Aeronautics (NACA). Glenn began operation in 1942 as the NACA Aircraft Engine Research Laboratory (AERL). In 1947 the NACA renamed the lab the Flight Propulsion Laboratory to reflect the expansion of the research. In September 1948, following the death of the NACA's Director of Aeronautics, George Lewis, the NACA rededicated the lab as the Lewis Flight Propulsion Laboratory. On 1 October 1958, the lab was incorporated into the new NASA space agency and was renamed the NASA Lewis Research Center. Following John Glenn's return to space on the space shuttle, on 1 March 1999 the center name was changed once again, becoming the NASA John H. Glenn Research Center
