    The steps necessary to isolate equipment are often documented in an isolation procedure or a lockout tagout procedure. The isolation procedure generally includes the following tasks: [2] Announce shut off; Identify the energy sources; Isolate the energy sources; Lock and tag the energy sources; Demonstrate that the equipment isolation is effective

    Fractionation refers to a purification strategy in which some relatively inefficient purification method is repeatedly applied to isolate the desired substance in progressively greater purity. Electrolysis refers to the breakdown of substances using an electric current. This removes impurities in a substance that an electric current is run through

    In 2009, Reis et al. proposed the first version of the process-per-site model to isolate web pages based on the page's web origin. [11] This was improved upon in 2009 by the Gazelle research browser, which separated specific document frames based on their web principal, a security barrier that corresponded with the specific document that was being loaded.

    en.wikipedia.org/wiki/Real-root_isolation

    The first complete root-isolation procedure results of Sturm's theorem (1829), which expresses the number of real roots in an interval in terms of the number of sign variations of the values of a sequence of polynomials, called Sturm's sequence, at the ends of the interval.

  8. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Fractionation makes it possible to isolate more than two components in a mixture in a single run. This property sets it apart from other separation techniques. Fractionation is widely employed in many branches of science and technology. Mixtures of liquids and gasses are separated by fractional distillation by difference in boiling point.
