caust-, caus-, caut-, cauter-, cau- +
(Greek: fire, burn, burnt, burner; from kaustikos, "capable of burning" or "burning" and kaukstos, "combustible" and from kaiein, "to burn")
2. The use of a cautery, or a caustic agent, to medically or to surgically treat a lesion or to stop bleeding.
Cauterization is the burning of the body to remove or close a part of it. It is sometimes done for medical reasons, to treat some kind of wound in an area, for example. The main form of cauterization is electrocautery.
In the past, cauterization was used to stop heavy bleeding, especially during amputations.
Special medical instruments called cauters were used to cauterize arteries. During open-heart surgery, cauterization is used to close the many blood vessels in the cavity, as well as to remove vessels to be used for coronary artery bypass surgery.
2. To deaden, as to feelings or moral scruples; callous.
2. Any substance that destroys tissue upon application.
2. The extreme use of cold in destroying tissue as if by "burning" it.
2. A curved formed by the consecutive intersections of rays of light refracted through a lens.
3. That which burns by refraction, as a double convex lens, or the sun's rays concentrated by such a lens, sometimes used as a cautery.
2. The application of a needle or snare heated by electric current for the destruction of bodily tissue; such as, for removing warts or polyps and cauterizing small blood vessels to limit blood loss during a surgical procedure.
2. A method of removing warts or polyps by placing a needle or wire loop heated by a direct galvanic current on the tissue to be removed.
2. A hand-held, needle-like cautery heated by an electric current.
3. The application of a needle or snare heated by electric current for the destruction of tissue; such as, for removing warts or polyps (benign tumors) and cauterizing small blood vessels to limit blood loss during surgical procedures.
4. The process of cutting and cauterizing skin simultaneously, or coagulating blood from vessels around a surgical incision by using an electrical-cautery instrument.
5. Cauterization using platinum wires heated to red or white heat by an electric current, either direct or alternating.
2. A liquid substance which responds to electrical impulses to enable changeable text and image displays on a flexible surface.
This kind of ink will be used for applications; such as, e-books, electronic newspapers, portable signs, and foldable, rollable displays.
Electronic ink contains millions of tiny capsules filled with dark dyes and negatively charged white chips, that are floating in a substance like vegetable oil.
With a printer-like device, the electronic ink-coated material is exposed to electrical impulses which act on the white chips to make them display as light or dark-colored.
A pattern of charges when applied will make it possible for a display of images and text and such information to be displayed can be downloaded through a connection to a computer, a cell phone, or it can be created with mechanical tools; such as, something called an electronic "pencil".
