Castleshaw Roman fort was a castellum in the Roman province of Britannia.
 Although there is no evidence to substantiate the claim, it has been suggested that Castleshaw Roman fort is the site of Rigodunum, a Brigantian settlement.
 The remains of the fort are located on Castle Hill on the eastern side of Castleshaw Valley at the foot of Standedge but overlooking the valley.
 The hill is on the edge of Castleshaw in Greater Manchester.
 The fort was constructed in c. AD 79, but fell out of use at some time during the 90s.
 It was replaced by a smaller fortlet, built in c. 105, around which a civilian settlement grew.
 It may have served as a logistical and administrative centre, although it was abandoned in the 120s.
The Lunt Roman Fort is the archaeological site of a Roman fort, of unknown name, in the Roman province of Britannia.
 It is open to the public and located in the village of Baginton outside Coventry, Warwickshire.
 The fort has now been fully excavated and partially reconstructed; the wooden gateway was rebuilt by the Royal Engineers using the same tools and techniques that the military engineers of the Roman Army would have used.
Camp Catawba was a summer camp for boys near the town of Blowing Rock in the Blue Ridge Mountains of North Carolina.
 It was established in 1944 by Vera Lachmann (1904–1985), a poet, classicist and educator who emigrated from Germany in 1939.
 In 1947 she was joined by the composer Tui St. George Tucker (1924–2004), who was the camp's music director.
 Camp Catawba closed after the 1970 season.
 The camp's nearest neighbors and indispensable practical aids were Mr. and Mrs. Ira W. and Sally Lentz Bolick, a mountain farm couple who descended from 18th-century German immigrants to America.
Bremetennacum, or Bremetennacum Veteranorum, was a Roman fort on the site of the present day village of Ribchester in Lancashire, England (grid reference [ SD650350] ).
 (Variant names include "Bremetonnacum", "Bremetenracum" or "Bresnetenacum").
 The site is a Scheduled Ancient Monument.
Ardoch Roman Fort is an archaeological site just outside the village of Braco in Perthshire, Scotland, about 7 miles south of Crieff.
 At Ardoch are the remains of a Roman fort and several marching camps which included a signal tower.
 Part of the Roman Gask Ridge, it is said to be one of the most complete Roman camps in Britain, and is one of the best-preserved series of Roman military earthworks in the whole Empire.
Bewcastle Roman Fort was a Roman fort, built to the north of Hadrian's Wall as an outpost fort and intended for scouting and intelligence.
 The Roman name for the fort was Fanum Cocidi (as recorded in the Ravenna Cosmography), and means 'The Shrine of Cocidius', a deity worshipped in northern Britain.
 The remains of the fort are situated at the village of Bewcastle, Cumbria, 7 mi to the north of the Roman fort at Birdoswald, on Hadrian's Wall.
Chester-le-Street ( ) is a town in County Durham, England.
 Its history goes back to the building of a Roman fort called Concangis.
 This Roman fort is the "Chester" (from the Latin "castra") of the town's name; the "Street" refers to the paved Roman road that ran north–south through the town, and which is now called Front Street (shown at right).
Longridge is a medium-sized town and civil parish in the borough of Ribble Valley in Lancashire, England.

 The parish of Longridge had a population of 7,546 recorded in the 2001 census, increasing to 7,724 at the 2011 Census.
Vinovia or Vinovium was a Roman fort and settlement situated just over 1 mi to the north of the town of Bishop Auckland on the banks of the River Wear in County Durham, England.
 The fort was the site of a hamlet until the late Middle Ages, but the modern-day village of Binchester is about 2 mi to the east, near Spennymoor.
 The ruins are now known as the Binchester Roman Fort .
Off-center ions in crystals are substitutional impurity ions whose equilibrium position is shifted away from the regular lattice site.
 The magnitude of the shift typically ranges from 0.2 to 1.0 Å.
 There are two possible mechanisms that can cause impurity ion displacement.
 If the impurity ion is smaller than the regular ion (by 10% or more), the displacement arises because the repulsive forces between the impurity ion and its nearest neighbors stabilizing the ion at the regular site are strongly weakened.
 If the impurity ion is bigger than the regular ion, the displacement arises because of different covalency of the chemical bonds with the nearest neighbors for the impurity and regular ions.
