For this reason, it has been hypothesized that increases in radon concentration is due to the generation of new cracks underground, which would allow increased ground water circulation, flushing out radon.
And I think print is in for a very, very, very challenging time, both on circulation grounds and on advertising grounds.
The piles also lifted each building off the ground, allowing air circulation to cool the soil and preventing further thawing.
I can't help feeling that it's partly the exaggeration of the severity of the threat of antisemitism which provides fertile ground for the circulation of stories and rumours suggesting that the authorities have cravenly appeased antisemites, stories that either have no basis in fact or are distortions of reality.
Mr. Brownridge said that Rolling Stone's rivals, particularly Blender, were losing ground, although the circulations of Maxim and FHM were still significantly higher than Rolling Stone's.
Several theories have been proposed to explain the low death rates among birds in Europe: limited or insufficient monitoring of deaths among wild birds in Europe; development of immunity among birds from infections acquired on wintering grounds (18 ); and circulation of WNV strains in Europe with reduced virulence for birds.
Study models: bike circulation and ground condition.
Similar to the ore channels formed by circulation of ground water written of by the later German scientist Georgius Agricola, Su Song made similar statements concerning copper carbonate, as did the earlier Rihua Bencao of 970 with copper sulphate.
Due to uneven microtopography, the chambers sat ∼3 cm off the ground, allowing for air circulation beneath the base of the greenhouses (Havstrom et al. 1993) and the unimpeded movement of ground dwelling insects into and out of the warmed plots.
Thermal conductivity of soil, initial temperature difference between circulation fluid and ground, and radius of the circulation tube are identified as the three most important parameters that control heat transfer through geothermal piles.
