The trail, going from west to east, travels through the Boardman River valley and follows the Au Sable River for about.

Oscoda is an unincorporated community in the U. S. state of Michigan located on the northern side of the Au Sable River where it enters Lake Huron.

The community of Au Sable is on the other side of the river.

* River Road National Scenic Byway, running parallel with the Au Sable River, is a designated National Scenic Byway for the that go into Oscoda.

Canoes along the Au Sable River

The Au Sable River Queen, the only paddlewheel river boat operating in northern Michigan

The Au Sable River in Michigan, United States runs approximately through the northern Lower Peninsula, through the towns of Grayling and Mio, and enters Lake Huron at Oscoda.

The Au Sable has a drainage basin of and an average flow of 1, 100 ft³ / s ( 31 m³ / s ) at its mouth.

The river flows south then turns east through Grayling, where it is joined by the East Branch Au Sable River at.

The Au Sable continues eastward and is joined by the South Branch Au Sable River at in South Branch Township.

The South Branch rises out of Lake St. Helen in Richfield Township, Roscommon County at and flows northwest into Roscommon then northeast to the main branch of the Au Sable.

The North Branch Au Sable River joins within approximately in eastern Crawford County at

The Au Sable then flows mostly east through Oscoda County, then south and east through Alcona County and Iosco County.

Most of the main branch of the Au Sable flows through or adjacent to the Huron-Manistee National Forest.

River Road, running parallel with the Au Sable River, is a designated National Scenic Byway.

There are six hydro-electric power plants in the Au Sable River basin, with a total installed capacity of 41 MW and an average annual energy output of 500 GJ.

The Au Sable has about of tributary streams including the Pine River.

Along the Au Sable River there are many places to stop.

It comes, along with the name of the River Aar ( which was called Arula, Arola, and Araris in early times ), from the German Au, meaning floodplain.

* Weyerhaeuser Au Sable River Canoe Marathon, starts in Grayling and ends in Oscoda down the river.

* Six miles west of Oscoda, on River Road Scenic Byway, the Au Sable River Queen offers paddle boat excursions.

The Au file format is a simple audio file format introduced by Sun Microsystems.

For purposes of international communication and trade, the official names of the chemical elements both ancient and more recently recognized are decided by the International Union of Pure and Applied Chemistry ( IUPAC ), which has decided on a sort of international English language, drawing on traditional English names even when an element's chemical symbol is based on a Latin or other traditional word, for example adopting " gold " rather than " aurum " as the name for the 79th element ( Au ).

It is a chemical element with the symbol Au and atomic number 79.

The symbol Au is from the, according to some sources meaning " shining dawn ", from Sabine ausum " glowing dawn " although according to definitions within Latin dictionaries the meaning of the word aurum extends only to the same as today's reference to the metal.

Gold has only one stable isotope, < sup > 197 </ sup > Au, which is also its only naturally occurring isotope.

The most stable of these is < sup > 195 </ sup > Au with a half-life of 186. 1 days.

The least stable is < sup > 171 </ sup > Au, which decays by proton emission with a half-life of 30 µs.

Gold's most stable isomer is < sup > 198m2 </ sup > Au with a half-life of 2. 27 days.

Gold's least stable isomer is < sup > 177 m2 </ sup > Au with a half-life of only 7 ns.

* On Point Au Roche, part of Beekmantown, New York, there is a privately owned, historic lighthouse.

Another practical application of STM is atomic deposition of metals ( Au, Ag, W, etc.

The song is recorded on their debut album, Pousse Au Crime et Longueurs de Temps.

Heat spike sputtering is most important for heavy ions ( say Xe or Au or cluster ions ) with energies in the keV – MeV range bombarding dense but soft metals with a low melting point ( Ag, Au, Pb, etc .).

* April 9 – French typesetter Edouard-Leon Scott de Martinville sings the French folk song " Au Clair de la Lune " to his phonautograph ; producing the world's earliest known sound recording ( however, it is not rediscovered until 2008 ).

* Au peninsula in Switzerland is first mentioned as " Owe " belonging to the commandry of the Knights Hospitaller in Bubikon.

Another touristic destination is the Au peninsula at the village of Au between Wädenswil and Horgen.

In some cases however — as with the < sup > 198 </ sup > Au cell shown here — a cell and its border are the same color so the border ’ s presence is denoted with a dotted margin.

Finally PCB is covered with soldermask, drilled, vias are plated again, and surface finish is applied ( best ROHS compatible surface finish is Au / Ni ).

The volatile species is the dimer Au < sub > 2 </ sub > Cl < sub > 6 </ sub >..
