Jona

Jona is a former municipality in the Wahlkreis (constituency) of See-Gaster in the canton of St. Gallen in Switzerland.

Geography

Jona is located at the eastern shore of Obersee. It has been part of the municipality of Rapperswil-Jona since 2007, as before comprising the villages of Bollingen, Busskirch, Curtiberg, Kempraten-Lenggis, Wagen and Wurmsbach (Wurmsbach Abbey).

History

The river Jona flows through the municipality in the Lake Zürich, the settlement is named after the river, first recorded in Latinized form Johanna in AD 834, as super Johannam fluvium. The Middle High German form Jonun is recorded 1243. The river name was likely adapted into Alemannic (Old High Geman) around the 8th century from a Gallo-Roman *Jauna as a weakly inflecting feminine *Jōna(n), yielding modern dialectal Jōne(n).

In 1350, Rapperswil and its castle was widely destroyed by Rudolf Brun, and the Herrschaft Rapperswil – Rapperswil and some surrounding villages including Jona – was acquired by the Habsburg family.

Jona (river)

The Jona is a river in the Swiss cantons of Zürich and St. Gallen.

Geography

The Jona rises on the eastern slope of Bachtel hill near Gibswil and Fischenthal in the Zürcher Oberland. Passing an impressive waterfall, the river flows near the municipality of Wald through a little valley eastward and changes its direction to the south by a ravine, which a viaduct of the Tösstalbahn (S26) is crossing. The Jona turns to the west, dividing the municipalities Dürnten and Rüti, passing the village of Tann and Rüti in the so-called Tannertobel. Once again, it changes its direction, flowing to the south (and slightly meandering) through Rüti and the so-called Joner Wald (forest of Rapperswil-Jona), followed by the S-Bahn Zürich lines S5 and S15. The river underneaths here Oberland Autobahn (A53 highway), now reaching the canton of St. Gallen and Rapperswil-Jona, flowing nearly in straight direction through the village of Jona (SG). Finally, it forms a small river delta near Busskirch and flows at Stampf lido in the Obersee, the upper section of the Zürichsee.

Adapa

Adapa, the first of the Mesopotamian seven sages, was a mythical figure who unknowingly refused the gift of immortality. The story is first attested in the Kassite period (14th century BC), in fragmentary tablets from Tell el-Amarna, and from Assur, of the late second millennium BC. Mesopotamian myth tells of seven antediluvian sages, who were sent by Ea, the wise god of Eridu, to bring the arts of civilisation to humankind. The first of these, Adapa, also known as Uan, the name given as Oannes by Berossus, introduced the practice of the correct rites of religious observance as priest of the E'Apsu temple, at Eridu. The sages are described in Mesopotamian literature as 'pure parādu-fish, probably carp, whose bones are found associated with the earliest shrine, and still kept as a holy duty in the precincts of Near Eastern mosques and monasteries. Adapa as a fisherman was iconographically portrayed as a fish-man composite. The word Abgallu, sage (Ab = water, Gal = great, Lu = man, Sumerian) survived into Nabatean times, around the 1st century, as apkallum, used to describe the profession of a certain kind of priest.

UAN

For the Sumerian sage, see Adapa.

UAN is a solution of urea and ammonium nitrate in water used as a fertilizer. The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers. The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) also known as UN32 or UN-32, which consists of 45% ammonium nitrate, 35% urea and only 20% water. Other grades are UAN 28, UAN 30 and UAN 18. The solutions are quite corrosive towards mild steel (up to 500 milliinches per year on C1010 steel) and are therefore generally equipped with a corrosion inhibitor to protect tanks, pipelines, nozzles, etc. Urea–ammonium nitrate solutions should not be combined with calcium ammonium nitrate (CAN-17) or other solutions prepared from calcium nitrate. A thick, milky-white insoluble precipitate forms that may plug nozzles and pipelines.
