Coordinates: 50°33′00″N 2°26′24″W / 50.550°N 2.440°W / 50.550; -2.440

The Isle of Portland is a limestone tied island, 6 kilometres (4 mi) long by 2.7 kilometres (1.7 mi) wide, in the English Channel. Portland is 8 kilometres (5 mi) south of the resort of Weymouth, forming the southernmost point of the county of Dorset, England. A barrier beach over which runs the A354 road connects it to Chesil Beach and the mainland. Portland and Weymouth together form the borough of Weymouth and Portland. The population of Portland is 12,400.

Portland is a central part of the Jurassic Coast, a World Heritage Site on the Dorset and east Devon coast, important for its geology and landforms. Its name is used for one of the British Sea Areas, and has been exported as the name of North American and Australian towns. Portland stone, famous for its use in British and world architecture, including St Paul's Cathedral and the United Nations Headquarters, continues to be quarried.

Portland Harbour, in between Portland and Weymouth, is one of the largest man-made harbours in the world. The harbour was made by the building of stone breakwaters between 1848 and 1905. From its inception it was a Royal Navy base, and played prominent roles during the First and Second World Wars; ships of the Royal Navy and NATO countries worked up and exercised in its waters until 1995. The harbour is now a civilian port and popular recreation area, and was used for the 2012 Olympic Games.

Portland (steam tug 1875)

The Portland was a steam tug built in Portland, Oregon, United States. This vessel was also known as Clayoquat and Phoenix.

Career

Portland was launched on April 9, 1875 in Portland, Oregon. The vessel was operated for 15 years on the Columbia and Willamette Rivers, and then was transferred to Puget Sound. From 1891 to 1895, the Portland operated out of Everett, Washington, piloted by Captain James Hastings.

Drift and recovery

In 1897, the Portland was hauled out at Ballard, Washington, for repairs. Somehow she broke free from the shipway and floated off unoccupied. Eventually, the Portland drifted north into Canadian waters, where she was recovered as a derelict by the B.C. Salvage Company. She came under the control of R.P. Rithet and Company, a prominent British Columbia shipping concern that repurposed her to a passenger steamer. She was renamed Clayoquat and ran on passenger routes out of Port Renfrew, on the west coast of Vancouver Island. Clayoquat later passed to the H.Bell-Irving Company, and was used by them as a cannery tender under the name Phoenix.

Portland, Connecticut

Portland is a town in Middlesex County, Connecticut, United States. The population was 8,732 at the 2000 census. The town center is listed as a census-designated place (CDP). It is situated across the Connecticut River from Middletown. Brownstone quarried in Portland was used in the construction of Hartford's Old State House in 1796. The vast majority of the brownstone buildings in Connecticut (see College Row at Wesleyan University and the Long Walk at Trinity College) as well as the famous brownstones in New York City were built with brownstone from Portland's quarries.

About half of the town's perimeter is made up of the Connecticut River. The town has eight marinas and boat clubs as well as three 18-hole golf courses.

History

The Wangunk tribe lived in the area prior to European settlement, and lived in Portland continuously throughout the settler period. Wangunk descendants still live in the area today. Their name referred to the bend in the Connecticut River which curves around half of the town's perimeter.

Rap GTP-binding protein

Rap GTP-binding protein also known as Ras-related proteins or simply RAP is a type of small GTPase, similar in structure to Ras.

These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. RAP counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner.

RAP99

The RAM P99 is a paintball marker manufactured by Chinese company Qian Wei and distributed in the United States by Umarex USA under the "Real Action Markers" brand. It is distributed in Europe by Umarex, Germany. The RAM P99 is made under license and designed to replicate the Walther P99.

Operation

Powered by a 12g disposable CO₂ cartridge or re-fillable internal air system, it features a blowback design and 9 shot capacity magazine using .43 caliber paintballs or rubberballs. The trigger is double-action (DA/SA). First versions did not have a conventional on/off safety. Current versions now have a manual trigger-lock safety. The marker is cocked by working the slide and there is also a functional de-cocker. It differs from the RAP4/5 system as it does not use (and therefore) eject shell casings. Muzzle velocity is adjustable between 200 ft/s and 300 ft/s. For .43 cal paintball - 0.029 oz it is about 3.4371 J (at 300 ft/s).

Use

The RAM P99 looks, feels and shoots with great accuracy just like the Walther P99 firearm making it ideal for law enforcement and military training, especially close quarter battles and room clearings. The RAM P99 is also used for virtual reality paintball play.
