https://en.wikipedia.org/wiki/Negative%20room%20pressure | Negative room pressure is an isolation technique used in hospitals and medical centers to prevent cross-contamination from room to room. It includes a ventilation that generates negative pressure (pressure lower than that of the surroundings) to allow air to flow into the isolation room but not escape from the room, a... |

https://en.wikipedia.org/wiki/Type%20erasure | In programming languages, type erasure is the load-time process by which explicit type annotations are removed from a program, before it is executed at run-time. Operational semantics not requiring programs to be accompanied by types are named type-erasure semantics, in contrast with type-passing semantics. Type-erasu... |
https://en.wikipedia.org/wiki/Lax%E2%80%93Friedrichs%20method | The Lax–Friedrichs method, named after Peter Lax and Kurt O. Friedrichs, is a numerical method for the solution of hyperbolic partial differential equations based on finite differences. The method can be described as the FTCS (forward in time, centered in space) scheme with a numerical dissipation term of 1/2. One ca... |
https://en.wikipedia.org/wiki/Wiedemann%E2%80%93Franz%20law | In physics, the Wiedemann–Franz law states that the ratio of the electronic contribution of the thermal conductivity (κ) to the electrical conductivity (σ) of a metal is proportional to the temperature (T).
Theoretically, the proportionality constant L, known as the Lorenz number, is equal to
where kB is Boltzm... |

https://en.wikipedia.org/wiki/Run-out | Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis. For example; when drilling, run-out will result in a larger hole than the drill's nominal diameter due to the drill
being rotated eccentrically (off axis instead of... |

History
A version that was in place from at least 1985 of the legislation, which was largely limited to praxis, combined with the approval features of the Canada Agricultural Products Act to govern the sph... |

https://en.wikipedia.org/wiki/Meijer%20G-function | In mathematics, the G-function was introduced by as a very general function intended to include most of the known special functions as particular cases. This was not the only attempt of its kind: the generalized hypergeometric function and the MacRobert E-function had the same aim, but Meijer's G-function was able to ... |
https://en.wikipedia.org/wiki/Microarray%20analysis%20techniques | Microarray analysis techniques are used in interpreting the data generated from experiments on DNA (Gene chip analysis), RNA, and protein microarrays, which allow researchers to investigate the expression state of a large number of genes - in many cases, an organism's entire genome - in a single experiment. Such experi... |
