  3. Waste hierarchy - Wikipedia

    en.wikipedia.org/wiki/Waste_hierarchy

    All products and services have environmental impacts, from the extraction of raw materials for production to manufacture, distribution, use and disposal. Following the waste hierarchy will generally lead to the most resource-efficient and environmentally sound choice but in some cases refining decisions within the hierarchy or departing from it can lead to better environmental outcomes.

  4. Resource recovery - Wikipedia

  5. Enhanced oil recovery - Wikipedia

    en.wikipedia.org/wiki/Enhanced_oil_recovery

    Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. Whereas primary and secondary recovery techniques rely on the pressure differential between the surface and the underground well, enhanced oil recovery functions by altering the physical or ...

  6. Recovery (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Recovery_(metallurgy)

    In metallurgy, recovery is a process by which a metal or alloy's deformed grains can reduce their stored energy by the removal or rearrangement of defects in their crystal structure. These defects, primarily dislocations , are introduced by plastic deformation of the material and act to increase the yield strength of a material.

  7. Criterion-referenced test - Wikipedia

    en.wikipedia.org/wiki/Criterion-referenced_test

    Domain-referenced test is similar to criterion-referenced test, it is an assessment that covers a specific area of study such that a score will reveal how much of this area has been mastered. Thus, if an individual got 90% of the items correct in a domain-referenced or criterion-referenced test, this would be a high score indicative of his or ...

    This page in a nutshell: Ideal sources for biomedical material include literature reviews or systematic reviews in reliable, third-party, published secondary sources (such as reputable medical journals), recognised standard textbooks by experts in a field, or medical guidelines and position statements from national or international expert bodies.

  9. Vital signs - Wikipedia

    en.wikipedia.org/wiki/Vital_signs

    Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery.
