  2. Gömböc - Wikipedia

    en.wikipedia.org/wiki/Gömböc

    At equilibrium, the center of mass and the contact point are on the line perpendicular to the ground. When the toy is pushed, its center of mass rises and shifts away from that line. This produces a righting moment, which returns the toy to its equilibrium position. The above examples of mono-monostatic objects are inhomogeneous.

    Partial equilibrium, the equilibrium price and quantity which come from the cross of supply and demand in a competitive market; Radner equilibrium, an economic concept defined by economist Roy Radner in the context of general equilibrium; Recursive competitive equilibrium, an economic equilibrium concept associated with a dynamic program

  4. Balance of nature - Wikipedia

    en.wikipedia.org/wiki/Balance_of_nature

    The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.

  5. Biological thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Biological_thermodynamics

    Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy.

    en.wikipedia.org/wiki/Gibbs–Donnan_effect

    Donnan equilibrium across a cell membrane (schematic). The Gibbs–Donnan effect (also known as the Donnan's effect, Donnan law, Donnan equilibrium, or Gibbs–Donnan equilibrium) is a name for the behaviour of charged particles near a semi-permeable membrane that sometimes fail to distribute evenly across the two sides of the membrane. [1]

  7. Stress (biology) - Wikipedia

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

    In biology, most biochemical processes strive to maintain equilibrium (homeostasis), a steady state that exists more as an ideal and less as an achievable condition. Environmental factors, internal or external stimuli, continually disrupt homeostasis; an organism's present condition is a state of constant flux moving about a homeostatic point ...

  9. Hill equation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Hill_equation_(biochemistry)

    The Hill equation can be applied in modelling the rate at which a gene product is produced when its parent gene is being regulated by transcription factors (e.g., activators and/or repressors). [11] Doing so is appropriate when a gene is regulated by multiple binding sites for transcription factors, in which case the transcription factors may ...
