  2. Carrying capacity - Wikipedia

    Carrying capacity is a commonly used concept for biologists when trying to better understand biological populations and the factors which affect them. When addressing biological populations, carrying capacity can be seen as a stable dynamic equilibrium, taking into account extinction and colonization rates.

  3. Light rail - Wikipedia

    There is no standard definition, but in the United States (where the terminology was devised in the 1970s from the engineering term light railway), light rail operates primarily along exclusive rights-of-way and uses either individual tramcars or multiple units coupled to form a train that is lower capacity and lower speed than a long heavy-rail passenger train or rapid transit system.

  4. pH - Wikipedia

    The measured pH is quantified in the aqueous phase only, by definition, but the value obtained is affected by the presence and nature of the soil colloids and the ionic strength of the aqueous phase. Changing the water-to-soil ratio in the slurry can change the pH by disturbing the water-colloid equilibrium, particularly the ionic strength.

  5. Integral - Wikipedia

    The definition of the Lebesgue integral thus begins with a measure, μ. In the simplest case, the Lebesgue measure μ(A) of an interval A = [a, b] is its width, b − a, so that the Lebesgue integral agrees with the (proper) Riemann integral when both exist.

  6. Computer - Wikipedia

    While popular usage of the word "computer" is synonymous with a personal electronic computer, the modern definition of a computer is literally: "A device that computes, especially a programmable [usually] electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes ...

  7. Attention - Wikipedia

    Attention is the behavioral and cognitive process of selectively concentrating on a discrete aspect of information, whether considered subjective or objective, while ignoring other perceivable information.

  8. Goal - Wikipedia

    Goal displacement occurs when the original goals of an entity or organization are replaced over time by different goals. In some instances, this creates problems, because the new goals may exceed the capacity of the mechanisms put in place to meet the original goals.

  9. Social norm - Wikipedia

    In Figure 1, the range of tolerable behavior extends is 3, as the group approves of all behavior from 4 to 7 and 7-4=3. Carrying over our coffee example again, we can see that first-years only approve of having a limited number of cups of coffee (between 4 and 7); more than 7 cups or fewer than 4 would fall outside the range of tolerable behavior.
