Marshalling convincing scientific data, they tell us that the environmental degradation caused by massive pollution of air water and land, threatens the very life of earth — fast depletion of non renewal resources, indeed of species themselves, the thinning of the ozone layer that exposes all living creatures to the danger of radiation, the build up of gases creating the greenhouse effect, increasing erosion by the sea — all these are brought out through their research.

The next decade, studies of the cosmic microwave background (the relic radiation from the Big Bang) by the Wilkinson Microwave Anisotropy Probe, or WMAP, provided a new way to measure the total amount of dark matter; this is the same technique that the Planck spacecraft built upon to come up with its more precise cosmic breakdown.

But the greatest damage to the complex, and the greatest release of radiation, may have been caused by explosions of hydrogen gas that built up inside some of the reactors.

The CALLISTO (Compound Astronomical Low - cost Low - frequency Instrument for Spectroscopy in Transportable Observatory) spectrometers, designed and built by electronics engineer Christian Monstein of the Institute for Astronomy of the Swiss Federal Institute of Technology Zurich (ETH Zurich), record the intensity of electromagnetic radiation at radio frequencies, between 45 and 870 megahertz.

It may also explain why other bodies in the Kuiper belt are unusually bright, the researchers say: Fresh ice is typically much brighter than an ancient stagnant surface on which dust and substances produced by interactions with sunlight or other radiation have built up through the ages.

That's where the Lyman - alpha radiation comes from: the glowing hydrogen gas that's being lit up by the young stars that are in these building blocks.

Townes» appointment as director of research for the U.S. government's Institute of Defense Analysis in 1959 slowed his efforts to build an optical device, opening the door for Theodore Maiman to demonstrate the first laser — light amplification by stimulated emission of radiation — in 1960.

After a series of brief studies by infrared instruments carried on sounding rockets had detected about 4,000 celestial sources of infrared radiation, the United States, the United Kingdom, and the Netherlands built IRAS to map the sky at infrared wavelengths of 12, 25, 60, and 100 micrometres.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

It is proposed by Realclimate that the extra down welling infrared radiation warms up that top single millimetre layer (they call it the ocean «skin») a tiny bit and apparently that is enough to disrupt the worldwide flow of heat energy from ocean to air to space with the result that the oceans release incoming solar energy more slowly so that heat builds up in the oceans.

The compression WORK gets converted to heat; BUT, once the collapse stops when teh pressure builds up enough to stop the fall, then the gas starts to lose energy and cool, by radiation, and eventually the whole thing would settle at a fixed Temperature.

Although radiation leakage has been reported, the reactor core containment is said still to be intact, But if the cooling operation is not successful then there is a risk that, aside from the (hopefully low) possibility of a explosion as at Chernobyl, or a hydrogen explosion (as was feared at one time at Three Mile Island in the USA), melting fuel could burn through the core and the floor of the reactor building and enter the soil, a risk that would be heightened if the floor structure was cracked by the earthquake.

By applying what has been learned about solar radiation changes from the recent measurements from space, we can infer that this gradual build - up in solar activity over several hundred years may have been accompanied by a parallel increase in the radiation received from the SuBy applying what has been learned about solar radiation changes from the recent measurements from space, we can infer that this gradual build - up in solar activity over several hundred years may have been accompanied by a parallel increase in the radiation received from the Suby a parallel increase in the radiation received from the Sun.
