Cumulative index to NASA Tech Briefs, 1986-1990, volumes 10-14

Tech Briefs are short announcements of new technology derived from the R&D activities of the National Aeronautics and Space Administration. These briefs emphasize information considered likely to be transferrable across industrial, regional, or disciplinary lines and are issued to encourage commercial application. This cumulative index of Tech Briefs contains abstracts and four indexes (subject, personal author, originating center, and Tech Brief number) and covers the period 1986 to 1990. The abstract section is organized by the following subject categories: electronic components and circuits, electronic systems, physical sciences, materials, computer programs, life sciences, mechanics, machinery, fabrication technology, and mathematics and information sciences

Utilizing Headspace Solid-Phase Microextraction for the Characterization of Volatile Organic Compounds Released from Contraband and its Implications for Detector Dog Training

Improving the accuracy and reliability of odor detection dogs is of utmost importance particularly for legal reasons. Field testing in conjunction with headspace analysis of volatile organic compounds (VOCs) has in recent times allowed for these improvements, by providing scientifically based recommendations for optimum training protocols. The current project leveraged on these established capabilities to enhance three areas of odor detection: illicit drugs, explosives and mass storage devices. With hemp being legalized under the 2018 Farm Bill, legal questions have been raised regarding a dog’s ability to ignore hemp if trained to detect marijuana, as both are types of Cannabis. Results concluded that most dogs do alert to hemp; however, they can be successfully trained over time to discriminate between hemp and marijuana. Headspace analysis showed marked similarities between sets of both products with minor differences. These differences can be further investigated to determine if characteristic marijuana VOCs exist that can be included in canine training regimens. Other tests showed that dogs imprinted on current marijuana odor mimics can falsely respond to hemp as the VOC components of these mimics are not specific to marijuana. These mimics should therefore be avoided for further training purposes. Dogs have been trained to detect and locate explosives such as triacetone triperoxide (TATP) that cannot be detected by most instrumental detectors. Headspace analysis showed TATP consisting primarily of the TATP molecule with relatively smaller amounts of the precursor acetone. Field tests determined that dogs imprinted on TATP may also falsely respond solely to the precursors acetone or hydrogen peroxide and as a result, additional training to ignore these VOCs should be considered. Detection of mass storage device (MSDs) is a relatively new field with little understanding of optimum training methods for dogs. Headspace analysis of various MSDs showed that they do have characteristic VOCs that can allow for successful odor detection with specificity. Additionally, the validity of 1-hydroxyclohexylphenyl ketone and triphenylphosphine oxide (TPPO) as training compounds were also investigated. 1-hydroxyclohexylphenyl ketone was detected in MSDs but also in other electronic controls while TPPO was not detected in MSD components
