(a) The Electronic Navigation Research Institute is conducting research and development work on satellite based technologies for air navigation and air traffic control.

(iv) To ensure the participation of affected groups and user groups in programmes for the control of indoor and outdoor air pollution, including encouraging local entrepreneurship in the introduction of new technologies to control indoor air pollution

The institute systematically conducts sanitary control of water for drinking and surface waters, food, and air.

The Council has also recommended a number of measures (customs control and air traffic control, in particular), both nationally and regionally, to improve monitoring of the embargo.

NASA initiated this research to control or prevent the buildup of medically harmful microorganisms in the air, water, and trace contaminant control systems of long duration on crewed spacecraft.

Its militants control parts of Iraq and Syria and a U.S. led coalition has conducted air strikes against them.

Likewise, ecological and human health research communities continue to advance systems for monitoring air pollution impacts. Such systems are critically important for determining priorities and evaluating the effectiveness of air quality control measures.

Effective control over land, air and sea routes around the Gaza Strip meant that legally speaking Israel was still the occupying Power.

Recognizing that effective control over man portable air defence systems acquires special importance in the context of the intensified international fight against global terrorism,

The mandate of the national police includes the control and monitoring of movement into and out of the national territory by land, lake and air.

However, a strong scientific and technical base is indispensable as a foundation for such systems, playing a critical role in setting appropriate emission standards and ambient air quality objectives, designing and implementing effective air pollution control strategies and technologies and assessing emissions, ambient air quality, exposure patterns and impacts on human and ecosystem health.

Recently, the importance of space technology and its use in the field of transport has increased, as reflected in such areas as meteorological and maritime observation, maritime geodetic control, search and rescue of ships and aircraft, air traffic control and operational control of ships, aircraft and land vehicles.

The United States is once again learning the limits of military power. In Iraq, America has unrivaled control of the air, but can t hold the ground.

(c) Development of a satellite data link, a system that improves the communication quality and surveillance capability of air traffic control for the safety of transoceanic flights.

Convinced of the importance of effective national control of transfers of man portable air defence systems and the safe and effective management of stockpiles of such weapons,

There is an EU Directive concerning the obligation of the Air Traffic Companies to provide the authorities responsible for documental control with details of the passenger's lists.

He stressed that Israel remained the occupying Power in the Gaza Strip since it continued to maintain effective control over land, air and sea around the Strip.

The Convention on Long range Transboundary Air Pollution and its associated protocols have been important instruments for enhancing international collaboration, and there has been significant progress in the development of integrated regional policies for air pollution assessment and control throughout Europe and North America.

(d) There is a need to improve and or establish air quality monitoring and control programmes for mobile and stationary emission sources and to secure financial resources and state of the art air quality measurement equipment and qualified personnel for data analysis and interpretation.

Andrea is a living air filter that absorbs toxic gasses from air, contaminated indoor air.

Air quality control has been carried out at times in a limited number of municipalities (20 per cent), and it is continuous in Banja Luka (city administration 1989 decision).

The most advanced observational and modelling tools, pollution prevention and control technologies and knowledge about best practices in air quality management must be shared effectively among industrialized and developing nations.

The major factor contributing to the bluest sky was the overall favorable meteorological conditions in recent days. And more importantly, Beijing had persistently carried out the air pollution control. It had vigorously promoted the Clean Air Action Plan in the past five years, and the environmental benefits were released continuously resulting in the reduction of total pollutant emission in the region. These laid the foundation for continuous improvement of air quality.

I'm still heating the air every time and cooling the air every time.

Convinced of the importance of effective national control of transfers of man portable air defence systems and their training and instruction materials and of the safe and effective management of stockpiles of such weapons,

Group of Eight Action Plan to Enhance Transport Security and Control of man portable air defence systems, Evian Summit 2003, and Group of Eight Secure and Facilitated International Travel Initiative, Sea Island Summit, 2004.

Convinced of the importance of effective national control of transfers of man portable air defence systems and related training and instruction materials and of the safe and effective management of stockpiles of such weapons,

Something's wrong with the air conditioner smell of burning V belts in the air.

Hot air rises, and air is drawn in off the sea to replace it.
