  2. Hunter syndrome - Wikipedia

    en.wikipedia.org/wiki/Hunter_syndrome

    Hunter syndrome is caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase (I2S). [2] [3] The lack of this enzyme causes heparan sulfate and dermatan sulfate to accumulate in all body tissues. [4] Hunter syndrome is the only MPS syndrome to exhibit X-linked recessive inheritance. [4] The symptoms of Hunter syndrome are comparable ...

  3. Sleeping in a closed room with an electric fan running does not result in "fan death", as is widely believed in South Korea among older people. [268] [269] As of 2019 this belief was in decline. [270] Nocturia (waking up at night to urinate) is equally prevalent in women and men, [271] although it is more common among both men and women over 50 ...

  4. Hurler syndrome - Wikipedia

    en.wikipedia.org/wiki/Hurler_syndrome

    Children with Hurler syndrome may appear normal at birth and develop symptoms over the first years of life. Symptoms vary between patients. [citation needed] One of the first abnormalities that may be detected is coarsening of the facial features; these symptoms can begin at 3–6 months of age. The head can be large with prominent frontal bones.

  5. Ceiling fan - Wikipedia

    en.wikipedia.org/wiki/Ceiling_fan

    A cast-iron ceiling fan made by Hunter, dating from the early 1980s. This model is called the "Original". The Hunter 'Original' (manufactured by the Hunter Fan Co.) is by far the most recognizable example of a cast-iron ceiling fan today. It has enjoyed the longest production run of any fan in history, dating from 1906 to the present day.

  6. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    Dimmer in a residential application with RF-based remote control. Non domestic dimmers are usually controlled remotely by means of various protocols. Analogue dimmers usually require a separate wire for each channel of dimming carrying a voltage between 0 and 10 V. Some analogue circuitry then derives a control signal from this and the mains ...

  7. D-dimer - Wikipedia

    en.wikipedia.org/wiki/D-dimer

    D-dimer (or D dimer) is a dimer that is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis.It is so named because it contains two D fragments of the fibrin protein joined by a cross-link, hence forming a protein dimer.

  8. Joel Spira (businessman) - Wikipedia

    en.wikipedia.org/wiki/Joel_Spira_(businessman)

    Compared to a rheostat-based circuit, the use of a thyristor greatly increases efficiency, as far less waste heat is generated. Dimming lights with a solid state dimmer also reduces total power draw, unlike rheostat dimmers. Spira's design (and most modern dimmers) rely on the use of AC power, and on the characteristics of incandescent lights.

  9. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    Therefore, the low speed of the training phase is a limitation of SVMs when it comes to its usage in fault detection and diagnosis cases. [20] Time domain waveform (top) and CWTS (bottom) of a normal signal. Artificial Neural Networks (ANNs) are among the most mature and widely used mathematical classification algorithms in fault detection and ...
