The results suggest that these storage units can be a source of vapors of VOCs in laboratories and the unnecessary exposure of laboratory workers to chemical vapors.
The only arbitrary model condition that still is applied is the stipulation of fixed boundary conditions on the vapor mixing ratios at 40 km, which are intended to provide a sink of sulfuric acid vapor and a source of water vapor, similar to what would occur if we were to simulate the thermochemistry in this domain.
The optimal filling ratio should maintain steady thin liquid film in heat source region of vapor chamber.
Although the exact source was not identified, the potential source of mercury vapor seemed to be residential apartments in five of the buildings with elevated mercury vapor concentration.
In addition to the ocean and monsoon, the Turkish plateau is also a second source of water vapor.
If there is a single source of hot vapor to be used in multiple heat exchangers, the flowsheet can use either a series or a parallel arrangement, depending on the temperature levels of the heat sinks.
To ensure that dental amalgams (a source of Hg vapor that readily enters the bloodstream) [ 4] did not confound our estimated fish concentration, we controlled for the number of maternal dental amalgams at the beginning of pregnancy.
At two sites, the probable source of mercury vapor emission was tracked to areas on the floor surface, one near a building entrance, the second on a stairway to a roof exit.
A worker's vapor exposure was extrapolated from three sets of factors: the tasks in his or her job associated with vapor sources, the characteristics of vapor sources (equipment and other facilities) at the work site, and the composition of petroleum products producing vapors.
Officials were trying to discover the source of the vapors, which might be from chemical weapons agents that spilled and soaked into the ground, said Maj. Chet Kemp, a nuclear, chemical and biological officer at Bagram.
