(n.) An instrument for augmenting a very small quantity of electricity, so as to render it manifest by sparks or the electroscope.
Example Sentences:
(1) Orientation and curvature in doubler-root teeth (mesial and distal) were of 2 types.
(2) By analyzing the friction power, it was concluded that the most proper way for making of external telescope was the principle of "doubler" model of refractory material, while the other methods of making gave poor results.
(3) Objectivization of findings in highly endangered patients by the radiofibrinogen test, ultrasonic doubler, venography of contrast medium, section.
(4) The ultraviolet light source (300 nm) was a ring dye laser equipped with an intracavity frequency doubler, pumped by an argon ion laser.
(5) The machine was thus initially christened "The (Energy) Doubler" and later, as the oil-crisis of the 1970s took hold and financial prudence became the byword, "The (Energy) Saver".
(6) Dust was collected when the two flaxes were separately processed by industrial doubler and stapler machines.
Electroscope
Definition:
(n.) An instrument for detecting the presence of electricity, or changes in the electric state of bodies, or the species of electricity present, as by means of pith balls, and the like.
Example Sentences:
(1) Precordial leads were first used by Waller, whose capillary electroscope was too insensitive to detect the electric forces emanating from the human heart unless the electrode was placed over the precordium as near to the heart as possible.
(2) Historical data for 32P activity induced in sulfur by fast neutrons have been corrected for decay with a recent half-life value of 32P and recalculated with an experimentally determined efficiency ratio of the electroscope for beta rays from 32P and natural uranium used as a standard.
(3) A new electroscope has been designed from the conventional Haslinger tubes.
(4) Radiation detectors have progressed from photographic plates and the gold leaf electroscope to the routine use of improved scintillation detectors for imaging the three-dimensional distribution of radioactive materials in the body as a function of space and time.
