  2. Acetone–butanol–ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Acetone–butanol–ethanol...

    The ABE fermentation via Clostridium beijerinckii or Clostridium acetobutylicum for instance is characterized by product inhibition. This means that there is a product concentration threshold that cannot be overcome, resulting in a product stream highly diluted in water.

  3. Solid solution - Wikipedia

    en.wikipedia.org/wiki/Solid_solution

    a solid solution mixes with others to form a new solution The phase diagram in the above diagram displays an alloy of two metals which forms a solid solution at all relative concentrations of the two species. In this case, the pure phase of each element is of the same crystal structure, and the similar properties of the two elements allow for ...

  4. 1 42 polytope - Wikipedia

    en.wikipedia.org/wiki/1_42_polytope

    The rectified 1 42 is constructed by points at the mid-edges of the 1 42 and is the same as the birectified 2 41, and the quadrirectified 4 21. These polytopes are part of a family of 255 (2 8 − 1) convex uniform polytopes in 8 dimensions, made of uniform polytope facets and vertex figures , defined by all non-empty combinations of rings in ...

  5. McCabe–Thiele method - Wikipedia

    en.wikipedia.org/wiki/McCabe–Thiele_method

    For example, if the feed is a saturated liquid, q = 1 and the slope of the q-line is infinite (drawn as a vertical line). As another example, if the feed is saturated vapor, q = 0 and the slope of the q-line is 0 (a horizontal line). [2] The typical McCabe–Thiele diagram in Figure 1 uses a q-line representing a partially vaporized feed.

  6. 4+1 architectural view model - Wikipedia

    en.wikipedia.org/wiki/4+1_architectural_view_model

    Illustration of the 4+1 Architectural View Model. 4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.

  7. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− ⁠ 1 / 3 ⁠) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.

  8. Nassi–Shneiderman diagram - Wikipedia

    en.wikipedia.org/wiki/Nassi–Shneiderman_diagram

    A Nassi–Shneiderman diagram (NSD) in computer programming is a graphical design representation for structured programming. [1] This type of diagram was developed in 1972 by Isaac Nassi and Ben Shneiderman who were both graduate students at Stony Brook University. [2] These diagrams are also called structograms, [3] as they show a program's ...

  9. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    Here, the domain is 0 ≤ b ≤ 1 and 0 ≤ x ≤ 1 . The sine map ( 4-1 ) exhibits qualitatively identical behavior to the logistic map ( 1-2 ) : like the logistic map, it also becomes chaotic via a period doubling route as the parameter b increases, and moreover, like the logistic map, it also exhibits a window in the chaotic region .
