  2. VX (nerve agent) - Wikipedia

    en.wikipedia.org/wiki/VX_(nerve_agent)

    VX is an odorless and tasteless [13] [14] chiral organophosphorous chemical with a molecular weight of 267.37 g/mol. [15] Under standard conditions it is an amber-coloured liquid with a boiling point of 298 °C (568 °F), and a freezing point of −51 °C (−60 °F). [16]

  3. Reynolds number - Wikipedia

    en.wikipedia.org/wiki/Reynolds_number

    The Reynolds number is the ratio of inertial forces to viscous forces within a fluid that is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.

  4. Rate of climb - Wikipedia

    en.wikipedia.org/wiki/Rate_of_climb

    In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).

  5. V speeds - Wikipedia

    en.wikipedia.org/wiki/V_speeds

    V 1 is defined differently in different jurisdictions, and definitions change over time as aircraft regulations are amended. The US Federal Aviation Administration and the European Union Aviation Safety Agency define it as: "the maximum speed in the takeoff at which the pilot must take the first action (e.g., apply brakes, reduce thrust, deploy ...

  6. Electron mobility - Wikipedia

    en.wikipedia.org/wiki/Electron_mobility

    For example, the value of v sat is on the order of 1×10 7 cm/s for both electrons and holes in Si. It is on the order of 6×10 6 cm/s for Ge. This velocity is a characteristic of the material and a strong function of doping or impurity levels and temperature.

    The normal distribution is NOT assumed nor required in the calculation of control limits. Thus making the IndX/mR chart a very robust tool. Thus making the IndX/mR chart a very robust tool. This is demonstrated by Wheeler using real-world data [ 4 ] , [ 5 ] and for a number of highly non-normal probability distributions.

  8. VR (nerve agent) - Wikipedia

    en.wikipedia.org/wiki/VR_(nerve_agent)

    VR (Russian VX, VXr, Soviet V-gas, GOSNIIOKhT substance No. 33, Agent "November") is a "V-series" unitary nerve agent closely related (it is an isomer) to the better-known VX nerve agent. [1] It became a prototype for the series of Novichok agents .

  9. Gaussian (software) - Wikipedia

    en.wikipedia.org/wiki/Gaussian_(software)

    Gaussian / ˈ ɡ aʊ s i ə n / is a general purpose computational chemistry software package initially released in 1970 by John Pople [1] [2] and his research group at Carnegie Mellon University as Gaussian 70. [3] It has been continuously updated since then. [4]
