Coronal gas

The thermosphere is the thin outer layer of our atmosphere extending from the mesopause near 80 km. altitude out to the exosphere, some several thousand kin. altitude, where the mean free path is sufficiently long to allow escape of atomic hydrogen and helium and atmospheric capture of coronal gas constituents. In the lower thermosphere, heated by solar ultraviolet and x-radiation, the temperature increases rapidly with altitude, with temperatures above 400 km. varying between about 700° and 2100°K., depending on solar activity. 

Two other structures can be identified in the ISM. One of these is called coronal gas, consisting of material ejected from stars, novae, supernovae, and other explosive objects in the universe. The temperature of coronal gas is very high, about 106 K, and it is composed of a complex mixture of elements contained within or produced by the star or nova. Although coronal gas has a very low density, its volume is very large, the largest of any other single type of structure found in the interstellar medium. 

Finally, the space not occupied by coronal gas, by HI or HII clouds, or by giant molecular clouds is occupied by the intercloud medium, consisting primarily of neutral hydrogen atoms. This "filler space occupies the second largest volume of the interstellar medium. 

The structure of the interstellar medium phases, and especially how they are spatially organized, is not fully elucidated. Large scale surveys of tracers of the neutral, ionized and coronal gas have led to determination of the global filling factors, and of the average physical conditions as listed in Table 2.1. The coronal gas, with temperatures in excess of 10 K is mostly formed by the bubbles created in... 

This weapon is based on the gas gun used by the KGB in the 50 s and 60 s. Many or the assassinations performed with this weapon were written off by the coroners involved as heart attacks. Whether they would be so identified today is uncertain, and defends entirely on the competence of the coroner. At east they allow time for the assassin to escape before the autopsy revealed the true cause of death. While it may be reloaded, it should be treated as a disposable weapon. The HCN is contained in a glass vial of 5cc capacity. If you have good glass blowing skills her-...

Immediately afterwards the Wiltshire Coroner took the unusual step of holding an inquest in camera. The only members of the public allowed inside the courtroom were personnel from Porton Down and the elderly parents of Leading Aircraftman Ronald Maddison, a twenty-year-old National Serviceman from Consett, County Durham. No details of the inquest were made public, and Maddison s father was instructed not to discuss his son s death, even with his wife. It proved impossible, however, to suppress the details of the airman s Death Certificate. The document revealed that Maddison had died from blocking of the bronchial tubes, a classic symptom of nerve gas poisoning. 

There was another inquest connected with Porton in 1953. The Director of the Chemical Defence Section committed suicide. No one suggested that the balance of his mind had been affected by his work with nerve gas, but his wife told the Wiltshire Coroner that her husband suffered from terrible depression. Sometimes, she said, he would come home late, explaining that he had stayed out... 

Mr Cayley died in July 1981 of chronic bronchitis. At a subsequent inquest he was recorded as having been killed by the King s enemies. Let this be a warning, added the Coroner, to anyone who plans using gas or bacterial warfare. This man suffered for more than sixty years as the result of First World War gassing. ... 

The solar system began to form about 4.55 Ae ago from a rotating disk of dust and gas (the solar nebula) which had sepatated from a larger molecular cloud a little earlier. The original composition of this disk can be obtained from two sources. The first of these are the spectral data from the sun. Rare earth abundances may be obtained both from photospheric absorption lines and coronal emission lines. These data are given in table 6 as atomic abundances relative to Si = 10 atoms (Aller 1987) and give the composition of the outer layers of the sun.

Probing questions were nonetheless being asked by the Coroner and the Treasury Solicitor s Department about how servicemen had been recruited and how their fitness had been tested, how they had been medically examined after volunteering and before taking part in the tests, and the type of information which had been brought to their attention to encourage them to volunteer. Most importantly, had these men been informed about the nature and purpose of the experiment or the risks involved Had they been exposed to undue risk The Coroner s handwritten notes, disclosed in 2004 for the first time, also reveal that at least one of the Porton scientists, John Rutland, believed that Maddison was exposed to levels of Sarin nerve gas...
