Cyclic compounds may or may not be aromatic.

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

In addition, we'll cover some powerful methods for reasoning about the running time of recursive algorithms like these.

The enzymes remanufactured the hydrocarbons into carbohydrates fungal sugars.

With respect to the possibility of exploiting hydrocarbons, the situation is different.

These are the same bonds that hold hydrocarbons together.

The enzymes remanufactured the hydrocarbons into carbohydrates fungal sugars.

Energy minerals include hydrocarbons such as petroleum and coal, and radioactive minerals.

In particular, oil from seepage at sea has penetrated into the freshwater lenses of atolls and coral limestone islands.

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

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

List known and reasonably anticipated hazardous decomposition products produced as a result of use, storage and heating. Hazardous combustion products should be included in Section 5 Fire fighting measures of the SDS.

The toroidal geometry made for a very efficient building every beam in this building is the same radius, all laminated wood.

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

Emissions of perfluorized carbons (PFCs) from aluminium producers have been reduced by 43 since 1985.

32. All major classes of hydrocarbons have been found at low concentrations in the Antarctic ecosystems.

A4.3.8.3.1 Consistent with good occupational hygiene practices, personal protective equipment (PPE) should be used in conjunction with other control measures, including engineering controls, ventilation, and isolation. See also Section 5 Fire fighting measures of the SDS for specific fire chemical PPE advice.

Concentrations of the breakdown products (oxidation products) of oil were found to be about 10 times higher than concentrations of their parent hydrocarbons.

data on emissions of other GHG (eg PFCs, HFCs, SF6), specifically

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.

As far as other major hydrocarbons, namely coal and radioactive minerals, are concerned, there are virtually no known deposits in most of the small island countries.

This dialogue, which already covers topics relating to living resources, could be extended to such other areas as hydrocarbons and communications.

Argentine and British delegations are meeting this week in Buenos Aires in order to find new ways of cooperating in the exploration and exploitation of hydrocarbons.

And out of this idea started spinning off many, many kinds of variations of different plans and possibilities, and then the plan itself evolved in relationship to the exhibits, and you see the intersection of the plan with the toroidal geometry.

(iii) The protection fabrics of ring nets shall be properly quot aligned quot and provided with the corresponding recently dated international certificate to ensure they are functioning efficiently

There are two main types of CCVs, circulating current type or blocking mode type, most commercial high power products being of the blocking mode type.

Island arc basins in the Caribbean Sea and the south west Pacific have been investigated for their hydrocarbon potential.

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.

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.

Working in conjunction with risk management software, the sensor system was reducing the risk of potential environmental contamination from hydrocarbon spillage.

The quot new quot fluoridized gases (PFCs and SF6) together contribute 8 of the total emissions.

The low levels of natural hydrocarbons and restricted human activity make the Antarctic ecosystem suitable as an indicator of global hydrocarbon pollution. 20

What it turned out, that all that we are seeing, all this liquid, is made of hydrocarbon and ethane and methane, similar to what you put in your car.

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).

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.

In 1962, France's early nuclear testing ground of Algeria became independent and the Moruroa atoll in the Tuamotu Archipelago was selected as the new testing site tests were conducted underground after 1974.

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.

Projections of emissions of the perfluorinated carbons (CF4 and C2F6), sulphur hexafluoride (SF6) and HFCs have been prepared on the basis of figures collected from the relevant branches and industrial enterprises.

The endangered Saimaa ringed seal, one of only three lake seal species in the world, exists only in the Saimaa lake system of southeastern Finland, down to only 300 seals today.

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.

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.

In that regard, the situation has unfortunately been affected recently by unilateral positions taken by the British Government on the sensitive matters of hydrocarbons quot .

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.

However, because the standard model is not mathematically self consistent under certain conditions (e.g., at very high energies, at which both quantum mechanics and general relativity are relevant), physicists believe that it is underlaid by some other theory, such as a grand unified theory, string theory, or loop quantum gravity.

11. The subtidal sediments in the near offshore areas of the ROPME sea area, from Kuwait to Qatar, were found to contain relatively low and uniform concentrations of polynuclear aromatic hydrocarbons.
