Eka or EKA may refer to:
Řeka (Polish: Rzeka , Cieszyn Silesian: Rzyka ) (literally a river) is a village in Frýdek-Místek District, Moravian-Silesian Region, Czech Republic. It had a population of 466 (2001 census), 21.5% of the population are the Poles. Village lies near the Moravian-Silesian Beskids mountains, and Ropičanka River flows through it. It lies in the historical region of Cieszyn Silesia.
The settlement along mountainous part of the Ropičanka River was led from Smilovice tracing back to the 16th century. In 1592 the noble owners of Smilovice had a litigation with Sidonia Catherine, the ruler of the Duchy of Teschen. From the accompanying document the established of the Řeka village can be inferred to happen around 1587. In 1643 the village was mentioned as rzeka Smilowiczka, in 1647 as na Smilowskej Rzice, later on the adjective referring to Smilovice was dropped in the 19th century. It belonged then to the Duchy of Teschen, a fee of the Kingdom of Bohemia and a part of the Habsburg Monarchy.
Dmitri Mendeleev published the first periodic table of the chemical elements in 1869 based on properties which appeared with some regularity as he laid out the elements from lightest to heaviest. When Mendeleev proposed his periodic table, he noted gaps in the table, and predicted that as-yet-unknown elements existed with properties appropriate to fill those gaps.
To give provisional names to his predicted elements, Mendeleev used the prefixes eka-, dvi-, and tri-, from the Sanskrit names of digits 1, 2, and 3, depending upon whether the predicted element was one, two, or three places down from the known element of the same group in his table. For example, germanium was called ekasilicon until its discovery in 1886, and rhenium was called dvi-manganese before its discovery in 1926.
The eka- prefix was used by other theorists, and not only in Mendeleev's own predictions. Before the discovery, francium was referred to as eka-caesium and astatine as eka-iodine. Sometimes, eka- is still used to refer to some of the transuranic elements, for example eka-radon for ununoctium and eka-actinium (or dvi-lanthanum) for unbiunium. But current official IUPAC practice is to use a systematic element name based on the atomic number of the element as the provisional name, instead of being based on its position in the periodic table as these prefixes require.
I bought a flat
Diminished responsibility
You're de ninth person to see
To be suspended in a seventh
Major catastrophe
It's a minor point but gee
Augmented by the sharpness of your
See what I'm going through
A to be with you
In a flat by the sea
