The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
9 m 3 (1.1 × 10. ^. 12 cu ft) per year. The Urengoy–Pomary–Uzhhorod pipeline (also known as the Bratstvo pipeline, Brotherhood pipeline, West-Siberian Pipeline, or Trans-Siberian Pipeline) is one of Russia 's main natural gas export pipelines, partially owned and operated by Ukraine. It was part of the "gas in exchange for pipes program ...
Pipe insulation made from rigid Phenolic, PIR, or PUR foam insulation is common in some countries. Rigid-foam insulation has minimal acoustic performance but can exhibit low thermal-conductivity values of 0.021 W/ (m·K) or lower, allowing energy-saving legislation to be met whilst using reduced insulation thicknesses.
Maximum discharge. 25.5 billion cubic meters per year. Diameter. 42 to 44 in (1,067 to 1,118 mm) The Langeled pipeline (originally known as Britpipe) is an underwater gas pipeline transporting Norwegian natural gas to the United Kingdom. Before the completion of the Nord Stream 1 pipeline, it was the longest subsea pipeline in the world.
A submarine pipeline (also known as marine, subsea or offshore pipeline) is a pipeline that is laid on the seabed or below it inside a trench. [1] [2] In some cases, the pipeline is mostly on-land but in places it crosses water expanses, such as small seas, straits and rivers. [3] Submarine pipelines are used primarily to carry oil or gas, but ...
The strength of the prism is increased until the streak of the light passes through the centre of the prism, as the strength of the prism indicates the amount of deviation present. The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens , which refracts light rays so that a point source of light is seen as a ...
2,000 km (1,200 mi) Maximum discharge. 90 billion cubic meters. The Central Asia – Center gas pipeline system is a Gazprom controlled system of natural gas pipelines, which run from Turkmenistan via Uzbekistan and Kazakhstan to Russia. The eastern branch includes the Central Asia – Center (CAC) 1, 2, 4 and 5 pipelines, which start from the ...
NEW YORK CITY (Reuters) -U.S. cities are breaking decades-old temperature records this week as a heat wave stretches from central to eastern portions of the country, the National Weather Service ...
