  2. Ventilatory threshold - Wikipedia

    en.wikipedia.org/wiki/Ventilatory_threshold

    A government experiment to test ventilatory threshold was held between November and December 2004. Subjects included 32 physically active males (age: 22.3; TV: 180.5; TM: 75.5 kg; VO2max: 57.1 mL/kg/min) encountered a continuous test of increasing loads on a treadmill, cardiorespiratory and other variables were observed using ECG (recording of ...

  3. Tidal volume - Wikipedia

    en.wikipedia.org/wiki/Tidal_volume

    Tidal volume: that volume of air moved into or out of the lungs during quiet breathing (VT indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.) FRC: Functional residual capacity: the volume in the lungs at the end-expiratory position: RV/TLC%

  5. Voltage transformer - Wikipedia

    en.wikipedia.org/wiki/Voltage_transformer

    Transformer winding primary (usually high-voltage) connecting wires are of many types. They may be labeled as H 1, H 2 (sometimes H 0 if it is internally designed to be grounded) and X 1, X2 and sometimes an X 3 tap may be present. Sometimes a second isolated winding (Y 1, Y 2, Y 3) (and third (Z 1, Z 2, Z 3) may also be available on the same ...

  6. Ventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Ventricular_tachycardia

    Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.

  7. Threshold voltage - Wikipedia

    en.wikipedia.org/wiki/Threshold_voltage

    For the n-channel depletion MOS transistor, a sufficient negative V GS will deplete (hence its name) the conductive channel of its free electrons switching the transistor “OFF”. Likewise for a p-channel "depletion-mode" MOS transistor a sufficient positive gate-source voltage will deplete the channel of its free holes, turning it “OFF”.

  9. Linux - Wikipedia

    en.wikipedia.org/wiki/Linux

    Many quantitative studies of free/open-source software focus on topics including market share and reliability, with numerous studies specifically examining Linux. [139] The Linux market is growing, and the Linux operating system market size is expected to see a growth of 19.2% by 2027, reaching $15.64 billion, compared to $3.89 billion in 2019 ...
