Traduction de «Propulseur à décomposition chimique » (Français → Anglais) :

The decomposition of pesticides occurs mainly as a result of biochemical action (bacterial activity), but can also be caused by photochemical reactions (exposure to sunlight) and chemical reactions.

2004 Report of the Commissioner of Firearms, tabled in the House of Commons, July 20, 2005 Statistics Canada table 254-0002, September 9, 2005 Question No. 180 Mr. Loyola Hearn: SWith regard to the U.S. booster rocket that was launched over Newfoundland and Labrador in May of 2005: (a) when was the government notified that the rocket was to be launched; (b) what was the government’s initial reaction to the notification of the launching of this rocket; (c) was there a request made by the government that the rocket not be launched and, if so, was the request an official request and was it oral or written; (d) was a Canadian environmenta ...[+++]l assessment performed before the launch of this rocket; (e) has a Canadian environmental assessment been performed since the launch of the rocket; (f) are there plans to do an environmental assessment; (g) what chemicals, if any, were deposited into the ocean as a result of the launching of this rocket; (h) was a clean-up of any chemicals performed as a result of the launching of this rocket and, if so, by whom and at what cost; (i) does the government have any scientific reports of the effects of the booster rocket chemicals on marine life; (j) is the government aware if the U.S. intends to launch future rockets over similar areas of our coastline and, if so, when will these rockets be launched; (k) has the booster been retrieved from the ocean floor; and (l) are there plans to retrieve the booster from the ocean floor and, if so, when and at what cost?

Environment Canada’s experts concluded that long-term environmental impacts were very unlikely. h) Based on the scenarios examined for potential release of the fuel into the marine environment, no chemical recovery is feasible. i) Environment Canada is unaware of any scientific reports of the effects of the booster rocket chemicals on marine life. j) The U.S. has several launches listed on the NASA public web site but the Government of Canada is not aware if the U.S. intends to launch future rockets over similar areas of our coastlines. k) The booster has not been retrieved from the ocean floor. l)There are no plans to retrieve the boost ...[+++]er from the ocean floor.

– the organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 ºC; or

This is because, in this market, i) competition is restricted to MMS and Alcatel Space Industries; and ii) Alcatel Space Industries depends on supplies by DASA for certain equipment products (i.e. chemical propulsion systems, chemical thrusters and on-board management systems).

To eliminate these concerns, the parties have undertaken to divest MMS' mechanical wheels business, and to grant licences for the manufacture and sale of equipment products (i.e. chemical propulsion systems, chemical thrusters and on-board management systems) supplied by DASA to Alcatel Space Industries, MMS' main competitor in military communication satellites in France.
