syn-, sy-, sym-, syl-, sys-

(Greek: with, together with; also by extension: united; same, similar; at the same time)

dissynagogue
To punish by casting out of the synagogue.
dyssymmetry
A lack of symmetry or something that has two sides or halves which are the same or very close in size, shape, and position.
economy class syndrome
1. A deep vein thrombosis (blood clot along the wall of a blood vessel), usually in the leg, caused by sitting immobile for long periods in a cramped aircraft seat.

Once movement begins again the clot can move to heart or lungs, causing rapid death.

2. A form of phlebitis (inflammation of a vein) in which a blood clot forms in the lower leg after prolonged immobility in a cramped space; such as, traveling in a confined space, like a coach seat on a crowded air flight.

It is known as economy class syndrom because so many travelers are turning up with phlebitis.

ectosymbiont
Symbiosis in which one symbiont lives on the outside of the body of the other.
ectosymbiont
An organism that lives on the surface of another organism to the benefit of both; such as, any of the microbes that normally live on the skin.
ectosymbiosis
Symbiosis between two organisms which are physically separated from each other.

Symbiosis refers to an organism interaction where one organism lives in intimate association with another one.

ectosymbiotic
A reference to an organism living on the surface of another organism.
egosyntonic (adjective), more egosyntonic, most egosyntonic
1. In psychology, of or relating to ideas, behaviors, or impulses that are acceptable to oneself.
2. A reference to something that is consistent with an individual's self-image.
electric converter, synchronous converter, converter
1. A converter in which motor and generator windings are combined on one armature and excited by one magnetic field; normally used to change alternating to direct current.
2. A synchronous machine used to convert alternating current (AC) to direct current (DC), or the reverse.

The AC-to-DC converter has been replaced by a mercury arc rectifier (for reasons of efficiency, lower maintenance costs, and fewer problems) or by motor-generator sets.

electron synchrotron
1. A machine which accelerates electrons in a circular path by keeping the frequency of the accelerating stream at a constant level while increasing the strength of the magnetic field guiding the stream.
2. A circular electron accelerator in which the frequency of the accelerating system is constant, the strength of the magnetic guide field increases, and the electrons move in orbits of nearly constant radius.
3. A synchrotron (an apparatus used in nuclear physics to produce beams of energetic charged particles and to direct them against various targets) designed to accelerate electrons.

The electron beam is allowed to strike an internal target, producing high-energy gamma rays which are used outside the machine.

electronic frequency synthesizer
An instrument that generates two or more selectable frequencies from one or more fixed-frequency sources.
electronic music synthesizer
An audio signal processor which contains sound generators (oscillators) and additional circuitry; such as, filters to produce familiar sounds including those produced by conventional musical instruments, or to create unique sounds and effects.
electronic waveform synthesizer
An apparatus that uses electron devices to generate an electrical signal of a desired waveform.
electrosynthesis
1. The use of electricity to synthesize or to process compounds by building up a complex compound with the union of simpler compounds or elements of chemical compounds.
2. The process of producing a compound by a chemical reaction or series of reactions, usually from simpler or commonly available starting materials that are induced by an electric current flow in an electrochemical cell.
electrotonic synapse
A gap junction which transmits electrical impulses in electrically excitable tissue.

A gap junction is an intercellular network of protein channels that facilitates the cell-to-cell passage of ions, hormones, and neurotransmitters.
