  2. Toxic unit - Wikipedia

    en.wikipedia.org/wiki/Toxic_unit

    Toxic units (TU) are used in the field of toxicology to quantify the interactions of toxicants in binary mixtures of chemicals. [1] A toxic unit for a given compound is based on the concentration at which there is a 50% effect (ex. EC50) for a certain biological endpoint.

  3. Isocost - Wikipedia

    en.wikipedia.org/wiki/Isocost

    The cost-minimization problem of the firm is to choose an input bundle (K,L) feasible for the output level y that costs as little as possible. A cost-minimizing input bundle is a point on the isoquant for the given y that is on the lowest possible isocost line. Put differently, a cost-minimizing input bundle must satisfy two conditions:

  4. Panegyrici Latini - Wikipedia

    en.wikipedia.org/wiki/Panegyrici_Latini

    Pliny's Panegyricus model is familiar to the authors of panegyrics 5, 6, 7, [18] 11, and especially 10, in which there are several verbal likenesses. Sallust's Bellum Catilinae is echoed in the panegyrics 10 and 12, and his Jugurthine War in 6, 5, and 12. [19] Livy seems to have been of some use in panegyric 12 [20] and Panegyric 8. [21]

  5. Cost breakdown analysis - Wikipedia

    Components of price. Image according to Garrett (2008), figure 4-1, p.65. In business economics cost breakdown analysis is a method of cost analysis, which itemizes the cost of a certain product or service into its various components, the so-called cost drivers.

  6. Isoquant - Wikipedia

    en.wikipedia.org/wiki/Isoquant

    The contour line of an isoquant represents every combination of two inputs which fully maximise a firm's use of resources (such as budget, or time). Full maximisation of resources is usually considered 'efficient'. Efficient allocation of factors of production occur only when two isoquants are tangent to one another.

  7. Total cost - Wikipedia

    en.wikipedia.org/wiki/Total_cost

    The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0. The total cost of producing a specific level of output is the cost of all the factors of production.

  8. Chemical synthesis - Wikipedia

    en.wikipedia.org/wiki/Chemical_synthesis

    Chemical synthesis (chemical combination) is the artificial execution of chemical reactions to obtain one or several products. [1] This occurs by physical and chemical manipulations usually involving one or more reactions. In modern laboratory uses, the process is reproducible and reliable.

  9. Hypergolic propellant - Wikipedia

    en.wikipedia.org/wiki/Hypergolic_propellant

    A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer. The main advantages of hypergolic propellants are that they can be stored as liquids at room temperature ...
