centrifuge (sh) and Portuguese language (sh)


centrifuge (sh)




Machine that applies a sustained centrifugal force.

Effectively, the centrifuge substitutes a similar, stronger force for that of gravity. Every centrifuge contains a spinning vessel; there are many configurations, depending on use. A revolving object exerts a force away from the centre of rotation (see Newton's laws of motion), called the centrifugal force; it is usually stated as so many "times gravity" or so many "G," and may range from a few G for the basket in a Home washing machine or an industrial separator to hundreds of thousands of G for centrifuges to separate isotopes of uranium or to purify vaccines.


Portuguese language (sh)




Romance language spoken by about 170 million people in Portugal, Brazil, and Other former Portuguese colonies.

The first literary works in Portuguese date from the 13th-14th century. Standard Portuguese is based on the dialect of Lisbon. Dialectal variation in Portugal is limited, but the differences between Brazilian and European Portuguese are more extensive, including changes in phonology, verb conjugation, and syntax. The four major dialect groups are Northern (Galician, spoken in northwestern Spain), Central, Southern (including the Lisbon dialect), and Insular (including Brazilian and Madeiran) Portuguese.
