  2. Food preservation - Wikipedia

    en.wikipedia.org/wiki/Food_preservation

    Many processes designed to preserve food involve more than one food preservation method. Preserving fruit by turning it into jam, for example, involves boiling (to reduce the fruit's moisture content and to kill bacteria, etc.), sugaring (to prevent their re-growth) and sealing within an airtight jar (to prevent recontamination).

  3. Electrical efficiency - Wikipedia

    en.wikipedia.org/wiki/Electrical_efficiency

    (10/20 × 100 = 50%) Electric kettle: more than 90% [citation needed] (comparatively little heat energy is lost during the 2 to 3 minutes a kettle takes to boil water). A premium efficiency electric motor: more than 90% (see Main Article: Premium efficiency). A large power transformer used in the electrical grid may have efficiency of more than ...

  4. Energy efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency

    Energy efficiency may refer to: Energy efficiency (physics) , the ratio between the useful output and input of an energy conversion process Electrical efficiency , useful power output per electrical power consumed

  5. Water efficiency - Wikipedia

    en.wikipedia.org/wiki/Water_efficiency

    Water efficiency is the practice of reducing water consumption by measuring the amount of water required for a particular purpose and is proportionate to the amount of essential water used. [ 1 ] [ 2 ] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [ 3 ]

  6. Mechanical efficiency - Wikipedia

    en.wikipedia.org/wiki/Mechanical_efficiency

    In mechanical engineering, mechanical efficiency is a dimensionless ratio that measures the efficiency of a mechanism or machine in transforming the power input to the device to power output. A machine is a mechanical linkage in which force is applied at one point, and the force does work moving a load at another point.

  7. Algorithmic efficiency - Wikipedia

    en.wikipedia.org/wiki/Algorithmic_efficiency

    Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or continuous process. For maximum efficiency it is desirable to minimize resource usage. However, different resources such as time and space complexity cannot be compared directly, so which of two algorithms is considered to be more efficient ...

    Voiced by: Rina Satō [3] (Japanese); Brittney Karbowski [2] (English) Mikoto Misaka (御坂 美琴) is one of the main heroines from the science side in A Certain Magical Index, as well as the main protagonist and the titular character of A Certain Scientific Railgun.

  9. Entomophagy in humans - Wikipedia

    en.wikipedia.org/wiki/Entomophagy_in_humans

    Insects generally have a higher food conversion efficiency than more traditional meats, measured as efficiency of conversion of ingested food, or ECI. [96] While many insects can have an energy input to protein output ratio of around 4:1, raised livestock has a ratio closer to 54:1. [ 97 ]
