  2. Reduction potential - Wikipedia

    en.wikipedia.org/wiki/Reduction_potential

    In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential ...

    Graphs of y = b x for various bases b: base 10, base e, base 2, base ⁠ 1 / 2 ⁠. Each curve passes through the point (0, 1) because any nonzero number raised to the power of 0 is 1. At x = 1, the value of y equals the base because any number raised to the power of 1 is the number itself.

    Other manufacturers used Control-X for this purpose. 10 Control-X was commonly used to cancel a line of input typed in at the terminal. 11 Control-Z has commonly been used on minicomputers, Windows and DOS systems to indicate "end of file" either on a terminal or in a text file. Unix / Linux systems use Control-D to indicate end-of-file at a ...

  5. Oxygen reduction reaction - Wikipedia

    en.wikipedia.org/wiki/Oxygen_reduction_reaction

    The oxygen reduction reaction is an essential reaction for aerobic organisms. Such organisms are powered by the heat of combustion of fuel (food) by O 2.Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer.

    Element in X[row 2; col 2] is changed (from 7) to a nested vector "Text" using the enclose ⊂ function. Element in X[row 3; col 4], formerly integer 14, now becomes a mini enclosed or ⊂ nested 2x2 matrix of 4 consecutive integers. Since X contains numbers, text and nested elements, it is both a mixed and a nested array.

  7. Tsiolkovsky rocket equation - Wikipedia

    A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

    Reduce benefits for new retirees. If Social Security benefits were reduced by 3% to 5% for new retirees, about 18% to 30% percent of the funding gap would be eliminated. [citation needed] Average in more working years. Social Security benefits are now based on an average of a worker's 35 highest paid annual salaries with zeros averaged in if ...

    A subset X of a ring or module is called saturated with respect to a multiplicative subset S if xs in X and s in S implies that x is in X. saturation The saturation of a subset of a ring or module is the smallest saturated subset containing it. semilocal semi-local 1. A semilocal ring is a ring with only a finite number of maximal ideals. 2.
