    This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes.Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics.

  4. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.

  5. Titanium nitride - Wikipedia

    en.wikipedia.org/wiki/Titanium_nitride

    Bulk ceramic objects can be fabricated by packing powdered metallic titanium into the desired shape, compressing it to the proper density, then igniting it in an atmosphere of pure nitrogen. The heat released by the chemical reaction between the metal and gas is sufficient to sinter the nitride reaction product into a hard, finished item.

    Figure 1. An UHTC strake composed of three different sections with different UHTC compositions. [4]Beginning in the early 1960s, demand for high-temperature materials by the nascent aerospace industry prompted the United States Air Force Materials Laboratory to begin funding the development of a new class of materials that could withstand the environment of proposed hypersonic vehicles such as ...

  8. Cast-iron cookware - Wikipedia

    en.wikipedia.org/wiki/Cast-iron_cookware

    The 20th century also saw the introduction and popularization of enamel-coated cast-iron cookware. Cast iron fell out of favor in the 1960s and 1970s, as teflon-coated aluminum non-stick cookware was introduced and quickly became the item of choice in many kitchens. The decline in daily use of cast-iron cookware contributed to the closure of ...

  9. Hypocalcemia - Wikipedia

    en.wikipedia.org/wiki/Hypocalcemia

    Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. [1] [3] [6] Mildly low levels that develop slowly often have no symptoms.
