Not long after his accession to office Gorchakov issued a circular to the foreign powers, in which he announced that Russia proposed, for internal reasons, to keep herself as free as possible from complications abroad, and he added the now historic phrase, La Russie ne boude pas ; elle se recueille (' Russia is not sulking, she is composing herself ').

In the 1980s, Edvard Ravnikar proposed the circular design and the granite block pavement, with a circle and radiant lines of Macedonian white-grey marble ( sivec ).

He proposed that any point in one retina might yield singleness of vision with a circular region centred around the corresponding point in the other retina.

The existence of such motion was first proposed by Erwin Schrödinger in 1930 as a result of his analysis of the wave packet solutions of the Dirac equation for relativistic electrons in free space, in which an interference between positive and negative energy states produces what appears to be a fluctuation ( at the speed of light ) of the position of an electron around the median, with a circular frequency of, or approximately 1. 6 Hz.

In one study for paracellular transport across the tight junction in kidney proximal tubule, a dual pathway model is proposed: large slit breaks formed by infrequent discontinuities in the TJ complex and numerous small circular pores.

PNNI also includes a very powerful summarization mechanism to allow construction of very large networks, as well as a call admission control ( CAC ) algorithm which determines the availability of sufficient bandwidth on a proposed route through a network in order to satisfy the service requirements of a VC or VP.

When the First Transcontinental Railroad was proposed in the 1850s, Atchison called for it to be built along the central route ( from St. Louis through Missouri, Kansas, and Utah ), rather the southern route ( from New Orleans through Texas and New Mexico ).

The growth brought to Docklands enabled the Jubilee Line to be extended in 1999 to east London by a more southerly route than originally proposed, through Surrey Quays, Canary Wharf and the Greenwich Peninsula ( which was the next regeneration area ) to Stratford.

The proposed system would cover a distance of some 25 km, with some 13 stations, many located in town centres along the route where existing transport terminals already exist.

Such construction of a canal along the route using the San Juan River was proposed in the early colonial era.

However, unlike the case with the First Transcontinental, the eastern terminus of the proposed Canadian Pacific route was not in rich Nebraskan farmland, but deep within the Canadian Shield.

In June 1845 Whitney led a team along part of the proposed route to assess its feasibility.

A survey after 1848 indicated that the best route for a southern route had been overlooked when the US accepted a boundary proposed by Mexico in their peace treaty.

During the visit Lincoln was to spend 2 hours with M & M engineer Grenville M. Dodge at the Pacific House Hotel discussing the merits of starting the railroad in Council Bluffs and was to visit Cemetery Hill there to look over the proposed route.

Coule has argued that schemes such as the one proposed by Alcubierre are infeasible as matter placed en route of the intended path of a craft has to be placed at superluminal speed.

Bahrain has been proposed as the possible site of Dilmun, a land mentioned by Mesopotamians as a trade partner, source of raw material, copper, and entrepot of the Mesopotamia and the Indus Valley Civilization trade route.

In August 1900, Yerkes decided to become involved in the development of the London Underground railway system after riding along the route of one proposed line and surveying the City of London from the summit of Hampstead Heath.

In 1964, an inside-the-Capital-Beltway extension of Interstate 70S, also known as the North Central Freeway, was proposed via a route known as " Option # 11 Railroad Sligo East ," up to 1 / 4 mile parallel to the B & O railroad upon a swath of land displacing 471 houses, that would have cut the city in two.

Hill did much of the route planning himself, travelling over proposed routes on horseback.

A proposed South-North Water Transfer Project involves several schemes to divert water from the Yangtze River: one in the western headwaters of the rivers where they are closest to one another, another from the upper reaches of the Han River, and a third using the route of the old Grand Canal.

The stock route was proposed as a way of breaking a monopoly that west Kimberley cattlemen had on the beef trade at the beginning of the 20th century.

James Isdell, an east Kimberley pastoralist and member of the Western Australian Legislative Assembly, proposed the stock route arguing that ticks would not survive in the dry desert climate on the trip south.

A railway route between Thailand and Burma had been surveyed by the British government of Burma at the beginning of the 20th century, but the proposed course of the line – through hilly jungle terrain divided by many rivers – was considered too difficult to complete.

Companies had to submit a Bill to Parliament to gain the right to acquire land for the line, which required the route of the proposed railway to be approved, but there were no limits on the number of companies and no real checks on the financial viability of a line.

Between Houlton and Brunswick, Maine, I-95 took a shorter inland route, much of it paralleling US 2 on the alignment proposed for US 1 in 1925.

Originally seen as a spur route, to be designated Interstate 297, it was planned to be built along the Maryland Route 3 corridor, but the proposed route was canceled because of local opposition.

* The originally proposed north – south route was to follow the current Maryland Route 10 corridor.
