Automated headspace analysis of fumigants 1,3-dichloropropene and methyl isothiocyanate on charcoal sampling tubes
Charcoal tubes are widely used for collecting organic vapor in the atmosphere, and the measurement is usually completed by analyzing an aliquot of the solvent phase following solvent extraction, typically with carbon disuhide. However, the sensitivity of this method is limited and sometimes too low for monitoring contaminants at trace levels in the environmental atmosphere. In this study, the p...
متن کاملWater and methyl isothiocyanate distribution in soil after drip fumigation.
Methyl isothiocyanate (MITC) generators, such as metam sodium (Met-Na), are used for soil fumigation of agricultural land. The ban on the fumigant methyl bromide has resulted in greater use of MITC generators. To understand the efficacy of MITC, it is necessary to assess its generation and disappearance kinetics when Met-Na is applied to soil. This study evaluated the movement of water and dist...
متن کاملHigh-Frequency Scattering from Water Saturated Sandy Sediments: Laboratory Study
Reported measurements of seabed scattering are largely confined to relatively low frequencies, up to 300 kHz, see, e.g., [Jackson and Richardson] and references therein. Still higher frequencies, up to a few megahertz, are used in seafloor imagery (e.g., in pencil-beam sonars), particularly to observe dynamic processes at the seafloor in shallow water. From the physics of sound-sediment interac...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
