The particle vaporizes and then recondenses on the surrounding surfaces.

261. The price reform (freeing electricity consumption prices and solid and liquid fuel prices) resulted in a drop in electric power consumption, as well as in emissions of sulphuric acid, solid particles and other pollutants of power generation.

1 The World Health Organization recognizes six main types of air pollutants carbon monoxide, nitrogen dioxide, particulate matter, sulphur dioxide, tropospheric ozone and suspended particulate matter.

Dust means solid particles of a substance or mixture suspended in a gas (usually air)

And not just iridium it's filled with glassy spherules, and it's filled with quartz grains that have been subjected to enormous pressure shock quartz.

Effluents and emissions are generated to some extent by production processes in a weapons complex and can be solid, liquid, gaseous and particulate in form.

The Particle Emissions Dilemma

A measuring cylinder can be used to measure amounts of liquids relatively precisely. Furthermore, the cylinder allows particulate matter to sink following this, the particulates can be separated from the fluid by decanting.

Renunciation of the use in space of motor systems powered by types of propellant whose combustion involves the formation of solid particles (a third of the combustion products of solid rocket motor fuels, for instance produce aluminium oxide particles of 0.0001 0.01 mm in size)

Observation of space debris (particles and objects)

The first satellite in China's space science satellite series and the world's first dark matter particle detection satellite, Wukong,

Spatially resolved images shall be recorded with ISOCAM in order to understand the distribution, properties and physical state of he dust grains.

At DARA DLR a study concerning the actual aspects of the space debris discussion is nearing completion, comprising, for example, additional space debris sources (RORSAT droplets, surface degradation particles, Al2O3 dust slag from solid rocket motor firings) or the minimum spacing required between the graveyard orbit and the geosynchronous Earth orbit (GEO).

That's a ball of water, and those are dirt particles.

Some of them are agglomerating together to form larger particles.

Lowering the level of black particles in the atmosphere would benefit both human health and the climate. Measures aimed at accomplishing this could be particularly effective in countries where emission standards for diesel fueled vehicles have not yet been introduced, and in countries, especially in Asia and Africa, where rural dwellings are heated by primitive stoves and food is prepared over open fires, causing large emissions of soot particles.

Mist liquid droplets of a substance or mixture suspended in a gas (usually air)

If you put particles in them, and they go shooting out the tip they're like miniature linear accelerators or electron guns.

And we chop those strands into what are called pellets.

There are particles and they move around with respect to a fixed, absolute framework of space and time.

B. Pollution modelling and cataloguing of objects and particles

Moreover, the evidence presented does not enable the Panel to draw any conclusions about the nature and extent of deterioration that could have been the result of contact with the particulate deposition.

D. Protection of space objects from hypervelocity particles

(i) The use of solid propulsion in orbit is prohibited (they create clouds of aluminium particles)

Under the programme to establish a space data transmission system, three further Gonets D1 space objects were launched to supplement the three already in orbit.

When a shell strikes, it added, a high proportion of the metal mass is converted into aerosol, which has particles that are easily airborne.

(b) Aluminium oxide slag and micro particles from orbital solid rocket motor firings

And this is a sheet of acrylic infused with colorless light diffusing particles.

(d) Solid propellant perigee kick motors that release aluminium particles are to be avoided

Iran estimates that up to 37 per cent of the polluting substances, including saline compounds, from the oil well fires in Kuwait were deposited on its territory.

Pursuant to the request of the Governing Council, the Panel, with technical assistance from the Post Conflict Assessment Unit of the United Nations Environment Programme ( UNEP ), has tracked the progress of activities related to the funded projects.

The combustion of fossil fuels, wood, and other biomass increases the amount of airborne particles, which, in a somewhat simplified manner, we can describe as white or black. Both types can be found in varying amounts in all emissions.

The dilemma is that all particles, whether white or black, constitute a serious problem for human health. Every year, an estimated two million people worldwide die prematurely, owing to the effects of breathing polluted air.
