  2. Endoscopic submucosal dissection - Wikipedia

    en.wikipedia.org/wiki/Endoscopic_submucosal...

    Endoscopic submucosal dissection (ESD) is an advanced surgical procedure using endoscopy to remove gastrointestinal tumors that have not entered the muscle layer. ESD may be done in the esophagus, stomach or colon. Application of endoscopic resection (ER) to gastrointestinal (GI) neoplasms is limited to lesions with no risk of nodal metastasis.

  3. Sigmoidoscopy - Wikipedia

    en.wikipedia.org/wiki/Sigmoidoscopy

    Sigmoidoscopy ("sigma", the Greek term for letter "s/ς" + "eidos" + "scopy": namely, to look inside an "s"/"ς"-like object) is the minimally invasive medical examination of the large intestine from the rectum through to the nearest part of the colon, the sigmoid colon.

  4. Electrostatic-sensitive device - Wikipedia

    en.wikipedia.org/wiki/Electrostatic-sensitive_device

    Symbol for an ESD protection device – EPA Alternate warning symbol Symbol of an ESD grounding point for all components. An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. [1]

  5. IEC 61000-4-2 - Wikipedia

    en.wikipedia.org/wiki/IEC_61000-4-2

    IEC 61000-4-2 is the International Electrotechnical Commission's immunity standard on electrostatic discharge (ESD). The publication is one of the basic EMC standards of the IEC 61000–4 series. The European equivalent of the standard is called EN 61000-4-2. The current version of the IEC standard is the second edition dated 2008-12-09. [1]

  6. Human-body model - Wikipedia

    en.wikipedia.org/wiki/Human-body_model

    Warning label for an electrostatic sensitive device, denoting the devices susceptibility to damage. A similar symbol without the bar and with a black "dome" denotes ESD-safe equipment. The human-body model (HBM) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge ...

  7. Charged-device model - Wikipedia

    en.wikipedia.org/wiki/Charged-device_model

    The charged-device model (CDM) is a model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge (ESD). The model is an alternative to the human-body model (HBM). Devices that are classified according to CDM are exposed to a charge at a standardized voltage level, and then tested for survival.

  8. Electrostatic discharge - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_discharge

    Electrostatic discharge (ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects.

  9. Ureterosigmoidostomy - Wikipedia

    en.wikipedia.org/wiki/Ureterosigmoidostomy

    A ureterosigmoidostomy is a surgical procedure wherein the ureters, which carry urine from the kidneys, are diverted into the sigmoid colon.It is performed as a secondary treatment in bladder cancer patients who have undergone cystectomy.
