The shaded area underneath the gate electrode is the depletion region of the metal-semiconductor contact. An increase or decrease of the gate voltage with respect to the source causes the depletion region to expand or shrink; this in turn changes the......

  • depolarizing blocking agent
    Depolarizing neuromuscular blocking drugs, of which succinylcholine is the only important example, act in a more complicated way than nondepolarizing, or competitive, agents. Succinylcholine has an action on the end plate similar to that of acetylcholine. When given systemically, it causes a sustained end-plate depolarization, which first stimulates muscle fibres throughout the body, causing......

  • deposit
    Most countries require banks to participate in a federal insurance program intended to protect bank deposit holders from losses that could occur in the event of a bank failure. Although bank deposit insurance is primarily viewed as a means of protecting individual (and especially small) bank depositors, its more subtle purpose is one of protecting entire national banking and payments systems by......
  • deposit, bank of
    Banks in Europe from the 16th century onward could be divided into two classes: exchange banks and banks of deposit. The last were banks that, besides receiving deposits, made loans and thus associated themselves with the trade and industries of a country. The exchange banks included in former years institutions such as the Bank of Hamburg and the Bank of Amsterdam. These were established to......

    Benthic organisms can be classified according to size. The macrobenthos are those organisms larger than 1 millimetre. Those that eat organic material in sediments are called deposit feeders (e.g., holothurians, echinoids, gastropods), those that feed on the plankton above are the suspension feeders (e.g., bivalves, ophiuroids, crinoids), and those that consume other fauna in the......

  • Deposition (work by Lorenzetti)
    Sometime during 1330–40, Lorenzetti worked on a number of frescoes in the lower church of S. Francesco, in Assisi. The “Deposition,” in its clarity of composition and the monumentality of the sculpture-like draperies, shows a sensitive response to the art of Giotto. Lorenzetti’s figures achieve corporeality by means of strong, only partly blended colours. The “Ma...

  • Deposition (work by Angelico)
    Angelico’s Deposition for Santa Trinità in Florence was once attributed to Monaco, who had begun it before he died in 1425. Monaco had divided it into a triptych and executed the pinnacles. Angelico, however, made it a unified altarpiece with a vast landscape dominated by a varicoloured hill town. It is perhaps an imaginative evocation of Cortona, where F...

The term is commonly used as a synonym for sedimentar...

  • deposition nucleus (meteorology)
    Ice nuclei are of three types: deposition nuclei, contact nuclei, and freezing nuclei. Deposition nuclei are analogous to condensation nuclei in that water vapour directly deposits as ice crystals on the aerosol. Contact and freezing nuclei, in contrast, are associated with the conversion of supercooled water to ice. A contact nucleus converts liquid water to ice by......
  • Deposition of Christ (work by Raphael)
    In 1507 Raphael was commissioned to paint the “Deposition of Christ” that is now in the Borghese Gallery in Rome. In this work, it is obvious that Raphael set himself deliberately to learn from Michelangelo the expressive possibilities of human anatomy. But Raphael differed from Leonardo and Michelangelo, who were both painters of dark intensity and excitement, in that he wished to.....

They occur as laterally continuous bands or horizons within sequences of shallow-water marine or nonmarine deposits. Their origin is commonly related to the existence of brief episodes of strong bottom-hugging currents capable of ripping up recently deposited, unconsolidated sediment. For example, shallow......
  • depositional fabric (geology)
    ...The orientation, or lack thereof, of the crystals or grains that make up a sedimentary rock constitutes one aspect of fabric. Genetically, there are two principal varieties of oriented fabrics: primary (or depositional) and secondary (or deformational). Primary fabrics are produced while the sediment is accumulating. For example, river currents and some submarine gravity flows generate......
  • depositional pseudomorph
    Pseudomorphs are formed by substitution, deposition, or alteration. In the formation of a pseudomorph by substitution, the original substance has been gradually removed and simultaneously replaced by another. A common example of this is petrified wood, in which all the cellulose fibres have been replaced by silica, even those in the bark. Pseudomorphs can be formed by deposition of one mineral......
  • depositional remanent magnetization (physics)
    A second mechanism operates when small grains of magnetic minerals settle into a sedimentary matrix, producing detrital remanent magnetism. It is hypothesized that the tiny grains orient themselves in the direction of the Earth’s magnetic field during deposition and before the final consolidation of the rock. The magnetism thus introduced appears to persist through later alteration and......
  • depositional terrace (geology)
    The treads of river terraces are formed by processes analogous to those that produce floodplains. In depositional terraces, however, the origin of the now abandoned floodplain is much less significant than the long-term episode of valley filling that preceded the final embellishment of the tread. The thickness of valley-fill deposits is much greater than anything that could be produced by......

    specialized form of barter in which goods are exchanged without any direct contact between the traders.
