    This review explores the book All Hell Breaking Loose: The Pentagons View on Climate Change, written by Micheal Klare, highlighting how the US national security offices are viewing and responding to the ominous looming threats posed by climate change

    Survival and growth of cut vs hooked commercial sponges in the Florida Keys

    Get PDF
    The present project was undertaken for the purpose of establishing whether a change in harvesting technique -- cutting rather than tearing the sponge loose-- could insure sponge regeneration and thus reduce the possibility of overfishing in the Florida Keys. (14pp.

    Localization and superconducting proximity effect in sandwiched potassium films

    Full text link
    Thin films of alkali metals when sandwiched at both surfaces by thin metal films loose their conductance. The superconducting proximity effect is used to investigate the change in the alkali film. On the length scale of the film thickness the electronic properties of the alkali film do not change noticeably although its conductance is dramatically reduced, corresponding to localized electrons.Comment: 13 pages, 5 figure

    In lieu of an abstract, below is the essay\u27s first paragraph. Taking after my mother now, I save receipts in the center billfold of my wallet. Loose change, half empty tubes of lipstick, gum wrappers. Postcards, photographs in albums, birthday cards, yearbooks signed by forgotten friends

    Simulating Wde-area Replication

    We describe our experiences with simulating replication algorithms for use in far flung distributed systems. The algorithms under scrutiny mimic epidemics. Epidemic algorithms seem to scale and adapt to change (such as varying replica sets) well. The loose consistency guarantees they make seem more useful in applications where availability strongly outweighs correctness; e.g., distributed name service

    Dynamic Moire Methods for Detection of Loosened Space Shuttle Tiles

    Get PDF
    Moire fringe methods for detecting loose space shuttle tiles were investigated with a test panel consisting of a loose tile surrounded by four securely bonded tiles. The test panel was excited from 20 to 150 Hz with in-plane sinusoidal acceleration of 2 g (peak). If the shuttle orbiter can be subjected to periodic excitation of 1 to 2 g (peak) and rigid-body periodic displacements do not mask the change in the Moire pattern due to tile looseness, then the use of projected Moire fringes to detect out-of-plane rockin appears to be the most viable indicator of tile looseness since no modifications to the tiles are required

    Influence of preparation procedures on the phenolic content, antioxidant and antidiabetic activities of green and black teas

    The influence of common tea preparation procedures (temperature, infusion time, consumption time interval and tea bag/loose-leaf) and the type of water used, on the total phenolic content (TPC), the radical scavenging activity and the alpha-glucosidase inhibitory activity were assessed. Higher TPC and antioxidant activity were obtained when using lower mineralized waters. Tea bags also evidenced higher antioxidant activity than loose-leaf samples. Under the same conditions (90 degrees C and five minutes of infusion time) green tea contains almost twice the quantity of polyphenols and the free radical scavenging ability of black tea. In the alpha-glucosidase assay all infusions were active (97-100 %). Furthermore, HPLC allowed to identify some of the polyphenols present in both teas and to monitor their composition change with time. After twenty-four hours, the antioxidant activity was maintained without significant changes, but a small decrease in enzyme inhibition was observed, although this activity was still very high.info:eu-repo/semantics/publishedVersio
