  2. Monod equation - Wikipedia

    en.wikipedia.org/wiki/Monod_equation

    μ is the growth rate of a considered microorganism, μ max is the maximum growth rate of this microorganism, [S] is the concentration of the limiting substrate S for growth, K s is the "half-velocity constant"—the value of [S] when μ/μ max = 0.5. μ max and K s are empirical (experimental) coefficients to the Monod equation. They will ...

  3. Tetration - Wikipedia

    en.wikipedia.org/wiki/Tetration

    For example, 2 tetrated to 4 (or the fourth tetration of 2) is = = = =. It is the next hyperoperation after exponentiation , but before pentation . The word was coined by Reuben Louis Goodstein from tetra- (four) and iteration .

  4. Chemostat - Wikipedia

    en.wikipedia.org/wiki/Chemostat

    The growth rate of the microorganism is controlled by manipulation of the inflow of fresh medium, while the population density is regulated through changing the concentration of the limiting nutrient. This open system allows researchers to maintain the exponential growth phase of cells for use in physiological experiments. [1]

  5. Logistic function - Wikipedia

    en.wikipedia.org/wiki/Logistic_function

    The standard logistic function is the logistic function with parameters =, =, =, which yields = + = + = / / + /.In practice, due to the nature of the exponential function, it is often sufficient to compute the standard logistic function for over a small range of real numbers, such as a range contained in [−6, +6], as it quickly converges very close to its saturation values of 0 and 1.

  6. Plant growth analysis - Wikipedia

    en.wikipedia.org/wiki/Plant_growth_analysis

    Plant growth analysis refers to a set of concepts and equations by which changes in size of plants over time can be summarised and dissected in component variables. It is often applied in the analysis of growth of individual plants, but can also be used in a situation where crop growth is followed over time.

  7. Gravitropism - Wikipedia

    en.wikipedia.org/wiki/Gravitropism

    Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are growing in the correct direction. Growth due to gravitropism is mediated by changes in concentration of the plant hormone auxin within plant cells.

    Concentration profile in a diffusion-controlled system for a spherical nucleus with radius , where is the concentration of atoms in the solid nucleus, is the concentration in the liquid right at the surface if the nucleus, is the equilibrium concentration in the liquid phase and + is the distance from the nucleus where the equilibrium ...
