    Threshold of pain pressure level for sound where prolonged exposure may lead to hearing loss [citation needed] ±300 Pa ±0.043 psi Lung air pressure difference moving the normal breaths of a person (only 0.3% of standard atmospheric pressure) [35] [36] 400–900 Pa 0.06–0.13 psi

  3. Elevated alkaline phosphatase - Wikipedia

    en.wikipedia.org/wiki/Elevated_alkaline_phosphatase

    Elevated levels of the alkaline phosphatase enzyme are reported among those who have obesity. A study reported there were higher serum levels of alkaline phosphatase in obese than in the non-obese. With elevated alkaline phosphatase levels, there is an increase in disproportionate intracellular fat depots and thereby releasing itself into the ...

  4. Hypercalcaemia - Wikipedia

    en.wikipedia.org/wiki/Hypercalcaemia

    Severe hypercalcaemia (above 15–16 mg/dL or 3.75–4 mmol/L) is considered a medical emergency: at these levels, coma and cardiac arrest can result. The high levels of calcium ions decrease the neuron membrane permeability to sodium ions, thus decreasing excitability, which leads to hypotonicity of smooth and striated muscle. This explains ...

  5. Mitrailleuse d'Avion Browning - F.N. Calibre 13,2 mm - Wikipedia

    en.wikipedia.org/wiki/Mitrailleuse_d'Avion...

    The 13.2 mm FN Browning was developed by FN as an improved version of the Browning.50 in (12.7 mm) air-cooled MG53 aircraft machine gun. Improvements to the original design included: making the weapon lighter, increasing the rate of fire and offering it in not just 12.7×99mm Browning, but also 13.2×99mm Hotchkiss, [10] the latter cartridge effectively being a 12.7×99mm Browning cartridge ...

  6. Iodine-123 - Wikipedia

    en.wikipedia.org/wiki/Iodine-123

    Iodine-123 (123 I) is a radioactive isotope of iodine used in nuclear medicine imaging, including single-photon emission computed tomography (SPECT) or SPECT/CT exams. The isotope's half-life is 13.2232 hours; [1] the decay by electron capture to tellurium-123 emits gamma radiation with a predominant energy of 159 keV (this is the gamma primarily used for imaging).

  7. VO2 max - Wikipedia

    en.wikipedia.org/wiki/VO2_max

    V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...

    en.wikipedia.org/wiki/13.2×92mmSR

    The 13.2 × 92 mm SR, also known as Mauser 13.2 mm TuF (German: Tank und Flieger; literally "tank and aircraft", historical military designation), is a semi-rimmed rifle and machine gun cartridge developed by the German Empire for anti-tank and anti-aircraft use which was introduced during World War I.

  9. Blood lead level - Wikipedia

    en.wikipedia.org/wiki/Blood_lead_level

    Blood lead level (BLL), is a measure of the amount of lead in the blood. [1] [2] Lead is a toxic heavy metal and can cause neurological damage, especially among children, at any detectable level. High lead levels cause decreased vitamin D and haemoglobin synthesis as well as anemia, acute central nervous system disorders, and possibly death. [3]
