For example, they may be synthetic organochlorides such as plastics and pesticides, or naturally occurring organic chemicals such as polyaromatic hydrocarbons (PAHs) and some fractions of crude oil and coal.

Iran points out that some of the hydrocarbons, such as polycyclic aromatic hydrocarbons, are very toxic.

The enzymes remanufactured the hydrocarbons into carbohydrates fungal sugars.

Burning hydrocarbons (natural gas and petrol) yields both water and CO2.

And as you're looking at this system, if hydrocarbons are concentrated sunlight, then bioenergy works in a different way. And we've got to start thinking of oil and other hydrocarbons as part of these solar panels.

Organochlorine hydrocarbons (e.g., DDT) could be separated into dichlorodiphenylethanes, cyclodiene compounds, and other related compounds.

In domestic refrigeration he stated that HFC 134a and hydrocarbons continued to be dominant alternatives.

A few deals to export Russian hydrocarbons to China can be expected, but not much more.

CAMBRIDGE The prices of hydrocarbons, minerals, and agricultural commodities have been on a veritable roller coaster.

Bacteria capable of digesting the hydrocarbons in petroleum are often used to clean up oil spills.

It consists of a complex mixture of hydrocarbons of various molecular weights, plus other organic compounds.

The reservoir must also be permeable so that the hydrocarbons will flow to surface during production.

But the distribution of proceeds from hydrocarbons is irregular, and the central government has accumulated significant arrears.

Putin, for his part, built a great energy power, turning the country into a banana republic with hydrocarbons.

Oil and gas companies are taxed 46 percent on income derived from the sale of hydrocarbons and derivative products.

3.10.1.6.1 A review of the medical literature on chemical aspiration revealed that some hydrocarbons (petroleum distillates) and certain chlorinated hydrocarbons have been shown to pose an aspiration hazard in humans. Primary alcohols, and ketones have been shown to pose an aspiration hazard only in animal studies.

Few countries are as dependent on the Persian Gulf region s hydrocarbons as is India, which imports almost 80 of its consumption.

Their good fortune is not due to their domestic policies, but to hydrocarbons in Azerbaijan s case and, in Belarus, to Russian subsidies.

The hydrocarbons sector secures Russian growth, undermines the power of Arab producers and OPEC, and thus promises a decrease in oil prices.

But the most crucial and almost always overlooked point about fracking is that shale gas, like all hydrocarbons, can be used only once.

This relatively rich, opposition controlled, ethnically mixed, and more conservative province, blessed with fertile lowlands and hydrocarbons, voted for autonomy by a wide margin.

George A. Olah prepared the so called magic acid, so named for its ability to attack hydrocarbons, by mixing antimony pentafluoride (SbF5) and fluorosulfonic acid (FSO3H).

There are over 600 known carotenoids they are split into two classes, xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons, and contain no oxygen).

Because natural gas combustion produces fewer greenhouse gases than other hydrocarbons, such as coal or oil, it can be a bridge to a less carbon intensive future.

Only the world s political and economic heavyweights, the main industrialized countries that remain by far the biggest consumers of hydrocarbons, can initiate change on a global scale.

Rising oil prices are due to the sharp increase in demand by the major consumers, which have not adopted effective policies to reduce their dependency on hydrocarbons.

The dry deposition was in the form of gaseous pollutants and soot particles containing heavy metals and polycyclic aromatic hydrocarbons, including benzoapyrene, which is a known carcinogen.

A few deals to export Russian hydrocarbons to China can be expected, but not much more. Nonetheless, the visit will highlight several important features of the bilateral relationship.

Indeed, the tax seems to fall mostly on foreign suppliers of coal (and to a lesser extend on foreign suppliers of hydrocarbons in the Middle East and Russia).

France, for its part, has on a number of occasions been the victim of accidents, raising questions about the maritime transportation of hydrocarbons and its serious environmental impact.

Climate change and improved banking and financial regulation head the current agenda, but soon global agreement will be needed on access to resources ranging from hydrocarbons to minerals to agriculture.

Restructuring relations between the state and the private sector in the hydrocarbons sector has provided the central government with the resources and capacities needed to rebuild an extremely weak state.

While being toxic to marine life, polycyclic aromatic hydrocarbons (PAHs), the components in crude oil, are very difficult to clean up, and last for years in the sediment and marine environment.

We regret, however, the specific focus on that issue, since safety and security measures in general should be strengthened for the maritime transportation of all hazardous materials and pollutants, particularly hydrocarbons.

And we've learned that, in this species and I suspect in others as well these hydrocarbons, this layer of grease on the outside of ants, is different as ants perform different tasks.

In 1960, with a newly installed democratic government, Hydrocarbons Minister Juan Pablo Pérez Alfonso led the creation of OPEC, the consortium of oil producing countries aiming to support the price of oil.

His Government continued to protest against and to reject all unilateral actions concerning the territory under dispute, including seismic prospecting for hydrocarbons and the sale of fishing licences in the area under dispute.

Stalin thrived on the barbaric forced industrialization that planted the seeds of the communist system s destruction. Putin, for his part, built a great energy power, turning the country into a banana republic with hydrocarbons.

On land, oil fields in Alaska and gas fields in northern Russia have been producing hydrocarbons on a large scale for many years, but the estimated reserves under the Arctic Ocean are much larger.

The heating of the stratosphere is caused by absorption of solar UV and IR radiation by methane and other hydrocarbons, which form in this part of the atmosphere as a result of methane photolysis.

And we've done experiments that show that that's because the longer an ant stays outside, the more these simple hydrocarbons on its surface change, and so they come to smell different by doing different tasks.

The technical assistance provided by UNOTIL legal advisers, in particular, proved essential to the development of the recently enacted Petroleum Fund Act, which lays the legal foundation for an accountable and transparent management of hydrocarbons.

Juan Enriquez challenges our definition of bioenergy. Oil, coal, gas and other hydrocarbons are not chemical but biological products, based on plant matter and thus, growable. Our whole approach to fuel, he argues, needs to change.

Photolysis in the atmosphere Photolysis also occurs in the atmosphere as part of a series of reactions by which primary pollutants such as hydrocarbons and nitrogen oxides react to form secondary pollutants such as peroxyacyl nitrates.
