  2. Paslode - Wikipedia

    en.wikipedia.org/wiki/Paslode

    In 1940, Paslode created the first Stapling Hammer. In 1959, the world's first Pneumatic nailer. By 1986, they had created the Impulse range of gas actuated nailing systems, commonly referred to as a nail gun. In 1986, ITW (Illinois Tool Works) acquired Paslode. The PASLODE brand joined the SPIT company in France in 2002.

    en.wikipedia.org/wiki/Staple_(fastener)

    A heavy duty office staple might be designated as F1667 STFCC-04: ST indicates staple, FC indicates flat top crown, C indicates cohered (joined into a strip), and 04 is the dash number for a staple with a length of 0.250 inch (6 mm), a leg thickness of 0.020 inch (500 μm), a leg width of 0.030 inch (800 μm), and a crown width of 0.500 inch ...

  4. List of radioactive nuclides by half-life - Wikipedia

    en.wikipedia.org/wiki/List_of_radioactive...

    This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.

  5. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    In this situation it is generally uncommon to talk about half-life in the first place, but sometimes people will describe the decay in terms of its "first half-life", "second half-life", etc., where the first half-life is defined as the time required for decay from the initial value to 50%, the second half-life is from 50% to 25%, and so on.

    en.wikipedia.org/wiki/Staple_gun

    A manual staple gun An electric stapler. A staple gun or powered stapler is a hand-held machine used to drive heavy metal staples into wood, plastic, or masonry.Staple guns are used for many different applications and to affix a variety of materials, including insulation, house wrap, roofing, wiring, carpeting, upholstery, and hobby and craft materials.

  7. List of nuclides - Wikipedia

    en.wikipedia.org/wiki/List_of_nuclides

    At least 3,300 nuclides have been experimentally characterized [1] (see List of radioactive nuclides by half-life for the nuclides with decay half-lives less than one hour). A nuclide is defined conventionally as an experimentally examined bound collection of protons and neutrons that either is stable or has an observed decay mode .

  8. Nickel–hydrogen battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–hydrogen_battery

    The open-circuit voltage is 1.55 V, the average voltage during discharge is 1.25 V. [9] While the energy density is only around one third as that of a lithium battery, the distinctive virtue of the nickel–hydrogen battery is its long life: the cells handle more than 20,000 charge cycles [4] with 85% energy efficiency and 100% faradaic efficiency.

  9. Isotopes of barium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_barium

    The longest-lived isomer is 133m Ba, which has a half-life of 38.9 hours. The shorter-lived 137m Ba (half-life 2.55 minutes) arises as the decay product of the common fission product caesium-137 . Barium-114 is predicted to undergo cluster decay , emitting a nucleus of stable 12 C to produce 102 Sn.
