Electromagnetic radiation emitted by high-energy particles following a curved path at close to the speed of light as in the variety of particle accelerator known as a synchrotron. It is also produced naturally by charged particles moving through magnetic fields.

Designates structures in which charged particles, generally subatomic particles such as protons or electrons, are accelerated by means of an alternating electric field whose frequency is kept constant to remain synchronous with the particles.They are confined to a closed circular orbit by a changing magnetic field, the strength of which is increased to keep the path’s radius constant as the particles gain mass and their momentum increases.

Syngenite is a hydrous sulfate of calcium and potassium occurring in tabular crystals. It is sometimes found as a salt deposit on masonry surfaces, a gray-white bloom on walls facing the prevailing wind and rain.

Paper manufactured using man-made fibers, typically synthetic resin derived from petroleum, which are bonded together with adhesives or heat and pressure.

Devices comprising a tube or pipe, often bent with one end placed in a container or reservoir of liquid, such as a bottle or basin, and the other end outside it at a lower level. The aim is to convey liquid upwards from the container and out from the lower end of the pipe or tube. The liquid is conveyed through differences in atmospheric pressure on the liquid in the upper container that pushes it into the tube as gravity pulls downwards the liquid in the lower length of tubing; another force that accounts for the rise of the liquid up the tube has been attributed to the cohesiveness or tensile strength of the moving liquid rather than to atmospheric pressure.

Nationality or culture of Syrause, Italy; especially used with reference to ancient Syracuse.

Dialect of Middle Aramaic that was once spoken across much of the Fertile Crescent and Eastern Arabia, dating to at least the 4th century BCE as a spoken language. It is known as a script from the 1st century CE. Classical Syriac became a major literary language throughout the Middle East from the 4th to the 8th centuries.

Scripts used for writing by the Syriac Christians from the 1st century ad until about the 14th century. Using a Semitic alphabet, it is descendent Aramaic cursive with 22 letters, all representing consonants, and was typically written from right to left, although occasionally vertically downward. Diacritical marks used to represent vowels were introduced in the 8th century and two systems of vocalization were developed, one similar to the system in Arabic, and one using small Greek letters above or below the line.
