  2. Flux (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Flux_(metallurgy)

    Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, [1] lime, [2] lead sulfide [3] and certain minerals containing phosphorus. Iron ore was also used as a flux in the smelting of copper.

  3. Oxygen cycle - Wikipedia

    en.wikipedia.org/wiki/Oxygen_cycle

    Main reservoirs and fluxes — in the biosphere (green), marine biosphere (blue), lithosphere (brown), and atmosphere (grey). The major fluxes between these reservoirs are shown in colored arrows, where the green arrows are related to the terrestrial biosphere, blue arrows are related to the marine biosphere, black arrows are related to the lithosphere, and the purple arrow is related to space ...

  4. Flux (metabolism) - Wikipedia

    en.wikipedia.org/wiki/Flux_(metabolism)

    Due to this, these methods make one key assumption which is that all fluxes into a given intracellular metabolite pool balance all the fluxes out of the pool. [ 5 ] This assumption means that for a given metabolic network the balances around each metabolite impose a number of constraints on the system.

  5. Flux (biology) - Wikipedia

    en.wikipedia.org/wiki/Flux_(biology)

    In general, flux in biology relates to movement of a substance between compartments. There are several cases where the concept of flux is important. The movement of molecules across a membrane: in this case, flux is defined by the rate of diffusion or transport of a substance across a permeable membrane.

  6. List of natural phenomena - Wikipedia

    en.wikipedia.org/wiki/List_of_natural_phenomena

    A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions, hurricanes and earthquakes.

    The area is of the surface the property is flowing "through" or "across". For example, the amount of water that flows through a cross section of a river each second divided by the area of that cross section, or the amount of sunlight energy that lands on a patch of ground each second divided by the area of the patch, are kinds of flux.

  8. Dissipative system - Wikipedia

    Examples in everyday life include convection, turbulent flow, cyclones, hurricanes and living organisms. Less common examples include lasers , Bénard cells , droplet cluster , and the Belousov–Zhabotinsky reaction .

  9. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal , and some states only exist under extreme conditions, such as Bose–Einstein condensates and Fermionic condensates (in extreme cold), neutron-degenerate matter (in extreme density), and ...
