Carbon fibers made from PAN have structure resembling narrow filaments of graphite, but thermal processing may re-order the structure into a continuous rolled sheet.

Carbon may also burn vigorously and brightly in the presence of air at high temperatures, as in the Windscale fire, which was caused by sudden release of stored Wigner energy in the graphite core.

Carbon storage in or under oceans may not be compatible with the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter.

Carbon dioxide may also be a by-product depending on the fuel, but the carbon emissions from an SOFC system are less than those from a fossil fuel combustion plant.

Carbon dating of textiles found with the remains in the cave indicate they are contemporaneous with the period of the Revolt and it is believed that as they were buried with pig bones ( a Roman practice ); this indicates that the remains may belong to Romans who garrisoned Masada after its recapture.

Carbon County may refer to:

It may contain as little as 0. 04 % Carbon ( by weight ).

However, evidence from Carbon Dating suggests that the stone circle which encircled Newgrange may not be contemporary with the monument itself but was placed there some 1, 000 years later in the Bronze Age.

Carbon dioxide at levels that are unusually high indoors may cause occupants to grow drowsy, get headaches, or function at lower activity levels.

Carbon Copy may refer to:

Similarly, introduction of a Carbon Emission Trading Scheme may feel good, but may be counterproductive if the cost of carbon is priced too low, or if large emitters are given " free credits ".

Carbon, or climate, neutrality is usually achieved by combining the following steps ( although these may vary depending whether the strategy is implemented by individuals, companies, organizations, cities, regions, or countries ):

Carbon deposit accumulation or erosion of its metal terminals may also cause distributor-cap failure.

Carbon dioxide may dominate over water in source regions.

Carbon dioxide, being poisonous at high partial pressures, could be a dangerous gas to have in a BC because the diver may inhale it from the bag underwater., but it is unlikely that this would happen, as the diver would usually be aware that the emergency inflation has been oprerated.

Carbon dating indicates that the construction of Nan Madol began around AD 1200, while excavations show that the area may have been occupied as early as 200 BC.

Carbon monoxide exposure may lead to a significantly shorter life span due to heart damage.

Carbon nanotubes may become a practical alternative to customary devices due to their small size and unique mechanical and electronic properties.

Inefficient and incomplete combustion of wood can result in elevated levels of greenhouse gases other than CO < sub > 2 </ sub >, which may result in positive emissions where the byproducts have greater Carbon dioxide equivalent values.

* Carbon monoxide ( CO )-A product of incomplete combustion, carbon monoxide reduces the blood's ability to carry oxygen ; overexposure ( carbon monoxide poisoning ) may be fatal.

Carbon flakes or nodules in iron or steel with high carbon content ( high carbon steel, cast iron ) may cause an electrolytic potential and interfere with coating or plating.

Carbon nanotubes may have the requisite tensile strength for the more technologically challenging Earth-based space elevator, but creation of nanotubes of the required length is a laboratory exercise, and adequate cable-scale technology has not yet been shown at all.

Carbon trading may refer to:

Carbon resistors and impurity-doped germanium resistors have been investigated for use as precision secondary thermometers in the liquid helium temperature region.

Carbon black was probably one of the first pigments to be used for tattooing, and Ötzi the Iceman was found to have carbon tattoos that survived during his life and for 5200 years after his death.

* Carbon nanocones, conical structures which are made predominantly from carbon and which have at least one dimension of the order one micrometer or smaller

Carbon neutral fuels have been proposed for distributed storage for renewable energy, minimizing problems of wind and solar intermittency, and enabling transmission of wind, water, and solar power through existing natural gas pipelines.

Rainwater absorbs fractional amounts of Carbon dioxide from the air as it falls, making a weak carbonic acid solution that eats into the limestone and eventually forms hollows and channels Local bedouin have always know these caves and some were used as water supplies.

Some snowboards incorporate the use of more exotic materials such as Carbon Fiber, Kevlar, Aluminium ( as a honeycomb core structure ), and have even incorporated Piezo dampers.

Carbon dioxide was predicted to have only a minor role.

Carbon isotopes of lipids ( n-alkanes ) derived from leaf wax and lignin, and total organic carbon from two sections of lake sediments interbedded with the in eastern North America have shown carbon isotope excursions similar to those found in the mostly marine St. Audrie ’ s Bay section, Somerset, England ; the correlation suggests that the end-Triassic extinction event began at the same time in marine and terrestrial environments, slightly before the oldest basalts in eastern North America but simultaneous with the eruption of the oldest flows in Morocco ( Also suggested by Deenen et al., 2010 ), with both a critical greenhouse and a marine biocalcification crisis.

Carbon and stainless spring steel wire have significant applications for engineered springs for critical automotive or industrial manufactured parts / components.

Carbon from this type of clathrate is isotopically heavier ( δ < sup > 13 </ sup > C is-29 to-57 ‰) and is thought to have migrated upwards from deep sediments, where methane was formed by thermal decomposition of organic matter.

This is available in Mac OS X v10. 2 or later, and gives Carbon programmers some of the tools that Cocoa developers have long been familiar with.

Carbon brakes have occasionally been applied to road cars, by the French Venturi sports car manufacturer in the mid 1990s for example, but need to reach a very high operating temperature before becoming truly effective and so are not well suited to road use.

Carbon County has a rich history, some interesting people have passed through her mountains, including Count Zinzendorf, Moravian mystic ; John James Audubon, Benjamin Franklin and many more.

In 2002, Calgon Carbon Corporation planned to construct a carbon reactivation plant in the airpark, though those plans have been delayed due to environmental concerns.

Scofield, sustained by several mines in Pleasant Valley, was still the largest town in Carbon County in 1915, when its citizens made an attempt to have the county seat moved to their community from Price, Utah.

Carbon dioxide-powered guns have two significant advantages over pre-charged pneumatic air guns:

Older applications written with the Carbon API have a potential issue when being ported to the current Intel Macs.

Carbon fibers derived from Polyacrylonitrile ( PAN ) are turbostratic, whereas carbon fibers derived from mesophase pitch are graphitic after heat treatment at temperatures exceeding 2200 C. Turbostratic carbon fibers tend to have high tensile strength, whereas heat-treated mesophase-pitch-derived carbon fibers have high Young's modulus ( i. e., high stiffness or resistance to extension under load ) and high thermal conductivity.

Carbon forks have become very common on racing bicycles of all frame materials.

This view is disputed and relates to a Carbon date from a standing stone setting which intersects with a later timber post circle, the theory being that the stone in question could have been moved and re-set in its original position at a later date.

Carbon shafts have the advantage that they do not bend or warp, but they can often be too light weight to shoot from some bows and are expensive.

Carbon fiber bows have become very popular, and some of the better carbon fiber bows are now comparable to fine pernambuco sticks.
