But as astronomers report online today in Nature, the galaxy is losing more gas than this — between three and 30 solar masses per year — as winds, radiation pressure, and supernova explosions from the starburst itself drive gas away.

The cloud forms a comet - like tail as a result of the starlight's radiation pressure pushing on the escaped hydrogen.

«The hypothesis to be tested experimentally in ADAPT was whether longer - lasting selective pressure by UV radiation results in a higher UV resistance, as well as in a higher resistance against further «extreme» environmental factors that exist in space,» Wassmann said.

In addition to the radiation pressure, the winds that so massive a star generates disperse its natal cloud, further limiting its growth as well as interfering with the formation of nearby stars.»

Risk factors for kidney cancer include tobacco use, obesity, high blood pressure, chronic renal failure, exposure to certain industrial chemicals, such as trichloroethylene, and radiation.

As a result, computing the transfer of infrared radiation throughout the atmosphere, with variations in pressure, temperature and concentration of each gas type, is a challenging problem that was not well understood until the 1950s.

The advantages are said to be: 1) the pressure drop caused by the mesh spreads the airflow evenly over the full surface of the absorber, and 2) the first layer of mesh acts as a radiation shield to reduce the radiation from the hotter inner layers toward the glazing.

Daily mean NCEP / NCAR reanalysis data are used as atmospheric forcing, i.e., 10 - m surface winds, 2 - m surface air temperature (SAT), specific humidity, precipitation, evaporation, downwelling longwave radiation, sea level pressure, and cloud fraction.

If there's no radiation from the Sun, no heat capacity in the model planet, no mass big enough to effect pressure changes («real» ideal gases which don't have mass), nothing much is happening because there's no movement, (movement from the play of hot and cold volumes as hot gases rise and cold sink, becoming less dense and gaining density), but,

(Sec. 1406) Authorizes FY2006 appropriations for the Secretary to study the application of radiation to petroleum at standard temperature and pressure to refine petroleum products, with the goal of reducing the capital investment and the operating energy costs for cracking oil, as well as its sulfur content.

With Longwave radiation the tendency is for the cooler object not to increase the temperature of the warm object, and if they are at the same air pressure, and ambient temperature - take 2 identical apples, one at 8C the other at 15C an inch apart, in a room at 20C — the likely outcome is that each apple reaches equilibrium with the ambient temperature of its own entropy, as if they were not in each other's presence.

The water vapor pressure is below the saturation value of 101325 Pa at 373.15 K (that isn't quite right either, but close enough) so there will be net evaporation of water from the surface as it warms from absorption of radiation and conduction from the water vapor.

The physics that must be included to investigate the moist greenhouse is principally: (i) accurate radiation incorporating the spectral variation of gaseous absorption in both the solar radiation and thermal emission spectral regions, (ii) atmospheric dynamics and convection with no specifications favouring artificial atmospheric boundaries, such as between a troposphere and stratosphere, (iii) realistic water vapour physics, including its effect on atmospheric mass and surface pressure, and (iv) cloud properties that respond realistically to climate change.

However, variables such as sea level pressure or top - of - atmosphere clear - sky shortwave radiation do not cover a sufficiently wide range in some.

If we increased the atmospherice pressure 90 fold, such as on venus, then there would be 90 times as much N2 per cubic meter, and the back radiation would go up proportionally, as would the surface temperature.

As the change of vapour pressure of ether is large for small changes of temperature the thermometer is very sensitive to small changes in the radiation falling on either bulb.
