Examples of sink in the following topics:

  • Sinking Funds

    • A sinking fund is a method by which an organization sets aside money to retire debts.
    • A sinking fund may operate in one or more of the following ways:
    • Thus the balance sheet consists of Asset = Sinking fund, Liability = Bonds
    • One purpose of a sinking fund is to repurchase outstanding bonds.
    • Describe how a sinking fund operates in regards to a bond issue

  • Transportation of Photosynthates in the Phloem

    • The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
    • Seeds, tubers, and bulbs can be either a source or a sink, depending on the plant's stage of development and the season.
    • The products from the source are usually translocated to the nearest sink through the phloem.
    • Once in the phloem, the photosynthates are translocated to the closest sink.
    • Sucrose concentration in the sink cells is lower than in the phloem STEs because the sink sucrose has been metabolized for growth or converted to starch (for storage) or other polymers (for structural integrity).

  • Global Warming Revisited

    • As an engine operates, heat flows from a heat tank of greater temperature to a heat sink of lesser temperature.
    • In a Carnot engine, which is the most efficient theoretical engine based on Carnot cycle, the maximum efficiency is equal to one minus the temperature of the heat sink (Tc) divided by the temperature of the heat source (Th).
    • This brings up two important points: optimized heat sinks are at absolute zero, and the longer engines dump heat into an isolated system the less efficient engines will become.
    • The excess heat lost by the engine is then released into the heat sink, which in the case of many modern engines would be the Earth's atmosphere.
    • As more heat is dumped into the environment, Earth's atmospheric (or heat sink) temperature will increase.

  • American Neutrality

    • When Wilson protested British violations of American neutrality, the British backed down, but still armed most merchant ships with medium-caliber guns that could sink submarines venturing above the surface.
    • The United States, however, demanded respect for international law, which protected neutral American ships on the high seas from seizure or sinking by any belligerent in the conflict.
    • The sinking of a large, unarmed passenger ship, combined with stories of atrocities by German troops occupying Belgium, shocked Americans and turned public opinion hostile to Germany, although not yet to the point of war .
    • This British propaganda poster urging participation in World War I shows the RMS Lusitania sinking in the background.
    • 1915 painting depicting the sinking of the Lusitania by the German U-Boat U-20.

  • Introduction to finding equivalence sets

    • For a first step, characterize each node as either a "source" (an actor that sends ties, but does not receive them), a "repeater" (an actor that both repeats and sends), or a "sink" (an actor that receives ties, but does not send).
    • The source is A; repeaters are B, C, and D; and sinks are E, F, G, H, and I.
    • In the neighborhood (that is, adjacent to) actor B are both "sources" and "sinks."
    • The same is true for "repeaters" C and D, even though the three actors may have different numbers of sources and sinks, and these may be different (or the same) specific sources and sinks.
    • Now consider our "sinks" (i.e. actors E, F, G, H, and I).

  • Volume and Density

    • When an object is placed in water, the object's relative density determines whether it floats or sinks.
    • An object with a higher density will sink.
    • The metals sodium (970 kg/m3) and potassium (860 kg/m3) will both float on water, while lead (11,340 kg/m3) will sink.
    • If ice did not float, it would sink to the bottom, allowing more ice to form and sink, until the lake froze solid!
    • This 4°C water has the highest density and sinks to the bottom of the lake.

  • Sources and Sinks of Essential Elements

  • Initial Reactions

    • Germany employed its major naval weapon, the submarine, to sink shipping bound for Britain or France .
    • But after two more attacks – the sinking of the British steamer Arabic in August 1915 and the torpedoing of the French liner Sussex in March 1916 – Wilson issued an ultimatum threatening to break diplomatic relations unless Germany abandoned submarine warfare.
    • 1915 painting depicting the sinking of the Lusitania by the German U-Boat U-20.

  • Neutral Rights and Submarines

    • The problem was that the U.S. demanded Germany respect international law, which protected neutral American ships on the high seas from seizure or sinking by either belligerent.
    • Britain armed most of its merchant ships with medium caliber guns that could sink a submarine, making above-water attacks too risky.
    • The sinking of a large, unarmed passenger ship, combined with the previous stories of atrocity from Belgium, shocked Americans and turned public opinion hostile to Germany, although not yet to the point of war .
    • They overestimated how many ships they could sink and how much that would weaken Britain.
    • 1915 painting depicting the sinking of the Lusitania by the German U-Boat U-20.

  • Flotation

    • If you put a metal coin into a glass of water it will sink.
    • When the buoyant force equals one ton, it will sink no further.
    • A 10,000-ton ship must be built wide enough to displace 10,000 tons of water before it sinks too deep in the water.
    • Likewise, an object denser than the fluid will sink.
    • Otherwise, the fraction submerged becomes greater than one—a sign that the object does not float at all, but it sinks!
