| synchrony | The simultaneous appearance of two separate events. Origin: syn-+ G. Chronos, time (05 Mar 2000) |
| synchrotron | A machine for generating high speed electrons or protons, as for nuclear studies. (05 Mar 2000) |
| synchrotron radiation | <physics> Electromagnetic energy radiated from a charged particle moving in a curved orbit (typically in a magnetic field), due to the acceleration required to change the direction of the particle's velocity. See: bremsstrahlung. Synonym: cyclotron radiation. (13 Jan 1998) |
| synchrotrons | Devices for accelerating protons or electrons in closed orbits where the accelerating voltage and magnetic field strength varies (the accelerating voltage is held constant for electrons) in order to keep the orbit radius constant. (12 Dec 1998) |
| synchysis | A derangement or confusion of any kind, as of words in a sentence, or of humors in the eye. <medicine> Sparkling synchysis, a condition in which the vitreous humor is softened and contains sparkling scales of cholesterin. Origin: NL, fr. Gr, fr. To confound; with + to pour. Source: Websters Dictionary (01 Mar 1998) |
| synchysis scintillans | An appearance of glistening spots in the eye, due to cholesterol crystals floating in a fluid vitreous. (05 Mar 2000) |
| syncinesis | Involuntary movement accompanying a voluntary one, as the movement of a closed eye following that of the uncovered one, or the movement occurring in a paralysed muscle accompanying motion in another part. Synonym: syncinesis. Origin: syn-+ G. Kinesis, movement (05 Mar 2000) |
| synclastic | <mathematics> Curved toward the same side in all directions; said of surfaces which in all directions around any point bend away from a tangent plane toward the same side, as the surface of a sphere; opposed to anticlastic. Origin: Pref. Syn- + Gr. Kla^n to break. Source: Websters Dictionary (01 Mar 1998) |
| synclinal | 1. Inclined downward from opposite directions, so as to meet in a common point or line. 2. <geology> Formed by strata dipping toward a common line or plane; as, a synclinal trough or valley; a synclinal fold; opposed to anticlinal. A downward flexure in the case of folded rocks makes a synclinal axis, and the alternating upward flexure an anticlinal axis. Origin: Gr. To incline together; with + to incline. <geology> A synclinal fold. Source: Websters Dictionary (01 Mar 1998) |
| syncline | <geology> A synclinal fold. Source: Websters Dictionary (01 Mar 1998) |
| synclinorium | Origin: NL, fr. Gr. To lay together + mountain. <geology> A mountain range owing its origin to the progress of a geosynclinal, and ending in a catastrophe of displacement and upturning. Source: Websters Dictionary (01 Mar 1998) |
| synclitic | Relating to or marked by synclitism. (05 Mar 2000) |
| synclitism | Condition of parallelism between the planes of the foetal head and of the pelvis, respectively. Origin: G. Syn-klino, to incline together (05 Mar 2000) |
| synclonic spasm | Clonic spasm of two or more muscles. (05 Mar 2000) |
