(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.
Repulsion
Definition:
(n.) The act of repulsing or repelling, or the state of being repulsed or repelled.
(n.) A feeling of violent offence or disgust; repugnance.
(n.) The power, either inherent or due to some physical action, by which bodies, or the particles of bodies, are made to recede from each other, or to resist each other's nearer approach; as, molecular repulsion; electrical repulsion.
Example Sentences:
(1) You float a tiny distance above, suspended by the repulsion between atoms.
(2) Following Nagle, we assume that the steric repulsions between chains and between head groups and the trans-gauche rotation energies are the dominant interactions in determining the transition and we describe the effect of the other interactions with a mean field approximation.
(3) Scattering techniques are also shown to be useful in studying intermicellar interactions, like the Coulomb repulsion between GM1 micelles, in the regime fo the long-range interactions obtainable at very low ionic strength.
(4) Ideal size-exclusion chromatography could be achieved only in a narrow range of the conditions: first, the mobile phase must contain a weak salting-out electrolyte such as NaCl, and second, the mobile phase pH must be high enough that hydrophobic interactions between the solute and support are balanced by their electrostatic repulsion.
(5) A model of functional epistasis is proposed in which it is assumed that coupling and repulsion genotypes differ in metabolic efficiency and thus in development time and net fecundity.
(6) Most repulsively of all, while rehabilitating convicted Nazi war criminals, the state prosecutor in Lithuania – a member of the EU and Nato – last year opened a war crimes investigation into four Lithuanian Jewish resistance veterans who fought with Soviet partisans: a case only abandoned for lack of evidence.
(7) Thinning is initially powered by gravity and capillary forces and will proceed in thin films (less than 100 nm) driven by intermolecular forces until the London-van der Waals attractive forces come to an equilibrium with electrostatic repulsion of similarly charged surfaces of the film.
(8) The compression isotherms of the two tetraether lipids PGC-I and DGC-I were very similar at pH 0, both molecules being uncharged, but at pH 5.6 or 8, PGC-I films were much more expanded than the neutral DGC-I, due to ionization of the phosphate group in PGC-I and the resulting charge-charge repulsion.
(9) We can survive this.” The bloodletting had names: two gunmen who came here to execute these “hundreds of idolatrous sinners” attending a “festival of perversion”, as Isis repulsively brands young fans of rock’n’roll.
(10) Calculation of the electrostatic repulsive force using measured charge densities indicates the existence of an attractive force which may be acting over several hundred angstroms.
(11) With larger separations substantial repulsion was obtained.
(12) The atrocities in Paris and Brussels are largely the work of people born and raised in France and Belgium, often from families repulsed by the ideologies of their sons.
(13) The measurements on the air-dried, but still hydrated layer were performed in the attractive imaging mode in which the forces between tip and sample are much smaller than in AFM in the repulsive mode or in scanning tunnelling microscopy (STM).
(14) The method is based on the affinity of a cation-exchange resin for doxorubicin and the repulsion by the same resin of negatively-charged liposomes.
(15) The introduction of a negative charge at position 41 through the replacement of Cys-41 by either aspartate or glutamate reduced the enzymatic activities to very low but measurable levels, suggesting a charge-charge repulsive interaction between these residues and possibly one or both of the phosphates of NAD.
(16) The agreement is not convincing for the sedimentation equilibrium at low ionic strength, because here the experimental DNA concentration is too high for the truncated dilute solution expansion of the DNA-salt repulsion.
(17) I never felt that way, and certainly the idea of putting anything foreign in my body was especially repulsive.
(18) While some politicians have sought to condemn the intolerance, such as President Joachim Gauck, who called the arson attacks “repulsive”, and warned that xenophobic attitudes had “hardened”, others, such as Horst Seehofer, the head of Bavaria’s conservative Christian Social Union party, have been accused of helping to fuel anti-foreigner feeling with repeated references to “en masse asylum abuse”.
(19) Foreigners thinking of visiting India – particularly young women – will find these views not only repulsive, but dangerous.
(20) The repulsive effect toward neurons can be neutralized by one of the monoclonal antibodies, but not by the other.
