Nór

Nór (Old Norse Nórr) or Nori is firstly a mercantile title and secondly a Norse man's name. It is stated in Norse sources that Nór was the founder of Norway, from whom the land supposedly got its name. (The name in fact probably derives from ‘nórðrvegr’, ‘northern way’.)

Chronicon Lethrens'

The Chronicle of Lejre (“Chronicon Lethrense”) written about 1170 introduces a primeval King Ypper of Uppsala whose three sons were Dan who afterwards ruled Denmark, Nori who afterwards ruled Norway, and Østen who afterwards ruled the Swedes. But the account then speaks only of the descendants of Dan.

Icelandic accounts

Source material

Parallel but not quite identical accounts of Nór the eponym of Norway appear in “Fundinn Nóregr” (‘Norway Found’), hereafter called F, which begins the Orkneyinga saga, and in Hversu Noregr byggðist (‘How Norway was Settled’), hereafter called B, both found in the Flatey Book.

About Thorri

King Thorri (Þorri 'frozen snow'), king of Finland, Kvenland and Götaland in B, was son of Snær ('Snow') the Old, a descendant of Fornjót (ruler of Finland and Kvenland in F). See Snær and Fornjót for further information. The name Þorri has long been identified with that of Þórr, the name of the Norse thunder god Thor, or thunder personified.

Gi alpha subunit

G_i alpha subunit (G_αi, or G_i/G₀ or G_i protein) is a heterotrimeric G protein subunit that inhibits the production of cAMP from ATP. A mnemonic for remembering this subunit is to look at first letter (G_αi = Adenylate Cyclase inhibitor).

Receptors

The following G protein-coupled receptors couple to the G_i subunit:

Function

G_i mainly inhibits the cAMP dependent pathway by inhibiting adenylate cyclase activity, decreasing the production of cAMP from ATP, which, in turn, results in decreased activity of cAMP-dependent protein kinase. Therefore, the ultimate effect of G_i is the opposite of cAMP-dependent protein kinase.

Gird

Gird (also can be known as Gopasetra in ancient times, or Gwalior region later) is a region of Madhya Pradesh state in central India. It includes the districts of Bhind, Gwalior, Morena, Sheopur, and Shivpuri. Gwalior is the largest city in the region, and its historic center.

The Chambal and Yamuna rivers form the northwestern and northern boundaries of the region. Hadoti region of Rajasthan lies to the southwest, Malwa region of Madhya Pradesh lies to the south, and Bundelkhand region of Madhya Pradesh and Uttar Pradesh lies to the east. Gird is sometimes considered part of Bundelkhand.

Geography

The region is semi arid characterized by black less fertile soil,rainfall of 200 to 300 mm/year, and winter temperatures that sometimes drop below 5 degrees Celsius. Major crops in the region include soyabean, gram and wheat and under assured irrigation, and guava, ber, aonla, and custardapple.

Great rhombidodecahedron

In geometry, the great rhombidodecahedron is a nonconvex uniform polyhedron, indexed as U₇₃. Its vertex figure is a crossed quadrilateral.

Related polyhedra

It shares its vertex arrangement with the truncated great dodecahedron and the uniform compounds of 6 or 12 pentagonal prisms. It additionally shares its edge arrangement with the nonconvex great rhombicosidodecahedron (having the square faces in common), and with the great dodecicosidodecahedron (having the decagrammic faces in common).

Filling

There is some controversy on how to colour the faces of this polyhedron. Although the common way to fill in a polygon is to just colour its whole interior, this can result in some filled regions hanging as membranes over empty space. Hence, the "neo filling" is sometimes used instead as a more accurate filling. In the neo filling, orientable polyhedra are filled traditionally, but non-orientable polyhedra have their faces filled with the modulo-2 method (only odd-density regions are filled in).
