This text is intended to provide an overview of methods for estimating the characteristics of vapor cloud explosions, flash flies, and boiling-liquid-expanding-vapor explosions (BLEVEs) for practicing engineers. The volume summarizes and evaluates all the current information, identifies areas where information is lacking, and describes current and planned research in the field. 

Our heron s still flying west. The crack in the clouds has widened and gleams of sun are catching a willow-tree top, a spangle of raindrops caught in a spider s web, the rough velvet of the meadow. 

Then the fog closed in. It was a soupy, ground-hugging tropical fog that my Chinese host assured me was known to last for weeks this time of year. I visited the airport the next day but it was clearly a futile gesture. The Bali plane circled the field four times looking for a hole in the cloud cover before giving up and flying on. I was no stranger to delay. Travel in Asia is made of delay. I returned to the hotel for another round of chess with the local chess fiends and assumed that the next day would be clear. 

For lower yield events, when all or most of the cloud remains below the tropopause, sampling has been more extensive, although still not necessarily representative. The Johnie Boy (0.5 kiloton) cloud, whose top was at about 4.3 km. (15,000 ft.), was sampled at several altitudes by airplanes flying through the cloud. The Koon (150 kilotons) cloud, with a top at about 17 km. (55,000 ft.), was sampled at the periphery only, but one sample was obtained from the region near the top of the... 

Mounting of the cloud water collectors on the aircraft is a critical issue because flow-field effects can easily distort the size distribution of drops. If at all possible, the collector should be mounted on a pylon so that the collector is in the free airstream. Substantially greater efficiencies can be achieved if the collector is mounted with a forward inclination of about 12° to 15° relative to a perpendicular from the aircraft longitudinal centerline. This kind of mounting accounts for the nose-up attitude at which most aircraft fly under cruise conditions and also provides a component of the airstream to drive impacted cloud droplets down the rod into the collection vessel, minimizing losses due to blow-off (28). 

Brenguier et al. (2003) discussed the ACE-2 CC project, one of the five projects accomplished within the ACE-2 program of the second field experiment on studies of aerosol characteristics with the aim of understanding the indirect climatic impact of aerosol for marine stratocumulus clouds and to substantiate the strategy of closed aerosol-cloud-radiation experiments. Observations within the CC project were made in June-July 1997 in the Canary Islands using instruments onboard three flying laboratories and installed at a surface network. 

Estimates show that nanosize drops formed in the plasma fly apart at a velocity of 104 cm/scc, whereas the velocity of expansion of the plasma cloud exceeds 106cm/sec. Accordingly, a microsecond after the laser pulse terminates the expanding plasma moves away from the target and charged nanodrops continue their movement in a vacuum, cool down to solidification, and the resulting nanoparticles finally arrive to the substrate surface. 

Tornadoes, or in other words, death and destruction, are the fastest winds on earth. Tornadoes are the rotating funnel clouds that extend high above clouds. Once these violent winds touch down almost nothing can stop them. They uproot trees, overturn railroad cars, and send automobiles flying like matchbox cars. Side effects from tornadoes are heavy rain, hail, lightning storms, and power outages. There have been hundreds of tornadoes reported annually since 1950, and they have killed over 10,000 people in the United States alone since 1900. Tornadoes, cyclones, and twisters are the most violent and unpredictable natural phenomenon the world has ever seen. 

Carbon-based sorbents are relatively new materials for the analysis of noble metal samples of different origin [78-84]. The separation and enrichment of palladium from water, fly ash, and road dust samples on oxidized carbon nanotubes (preconcentration factor of 165) [83] palladium from road dust samples on dithiocarbamate-coated fullerene Cso (sorption efficiency of 99.2 %) [78], and rhodium on multiwalled carbon nanotubes modified with polyacrylonitrile (preconcentration factor of 120) [80] are examples of the application of various carbon-based sorbents for extraction of noble metals from environmental samples. Sorption of Au(III) and Pd(ll) on hybrid material of multiwalled carbon nanotubes grafted with polypropylene amine dendrimers prior to their determination in food and environmental samples has recently been described [84]. Recent application of ion-imprinted polymers using various chelate complexes for SPE of noble metals such as Pt [85] and Pd [86] from environmental samples can be mentioned. Hydrophobic noble metal complexes undergo separation by extraction under cloud point extraction systems, for example, extraction of Pt, Pd, and Au with N, A-dihexyl-A -benzylthiourea-Triton X-114 from sea water and dust samples [87]. 

Leaves yellow plant weakened. Cause Whiteflies. These tiny, white, mothlike flies and their flattened, scalelike larvae feed on leaves, sucking out the plant juices. The adults often fly up in a cloud when you disturb an infested plant, Whiteflies secrete a sugary substance called honeydew, which makes leaves sticky and may encourage the growth of sooty mold fungus see Leaves with black coating below for more information.
