reduction of exhaust emissions is a major research task in diesel engine development in view of increasing concerns regarding environmental protection and stringent exhaust gas regulations. simultaneousreduction of nox emissions and particulate matter is quite difficult due to the soot/nox trade-off and isoften accompanied by fuel consumption penalties. towards this aim, automotive engineers ha...

Cucumber plants subjected to consecutive monoculture for 9 years were found to suffer from severe Fusarium wilt disease, caused by the soil-borne fungus Fusarium oxysporum f. sp. Cucumerinum J. H. Owen. In the present study, greenhouse experiments were performed to evaluate the influence of ammonia gas fumigation on Fusarium wilt suppression, fungal abundance and fungal community composition. R...

Sulfuryl fluoride is a colorless, odorless gas used as fumigant against pests during the storage of durable agricultural products. It also one alternatives to methyl bromide, which banned by Montreal Protocol. During fumigation, decomposition product sulfuryl residue can be formed in addition residue. Fluoride actually natural ingredient tea plant. However, within growing process plant concentr...

Currently hydrogen cyanide (HCN) is industrially produced in the Czech Republic (Lucebni zavody Draslovka Kolin) and is extensively used for Czech mill fumigation. Therefore we evaluated the potential of HCN fumigant for treatment of wooden transport packages (pallets). We tested the penetration of HCN trough wooden pallet materials using gas chromatography. The preliminary results on biologica...

in this paper, a model based on gmdh type neural network, is used to predict gas price in the spot market while using oil spot market price, gas spot market price, gas future market price, oil future market price and average temperature of the weather. the results suggest that gmdh neural network model, according to the root mean squared error (rmse) and direction statistics (dstat) statistics ...

The growth of indoor molds and their resulting products (e.g., spores and mycotoxins) can present health hazards for human beings. The efficacy of chlorine dioxide gas as a fumigation treatment for inactivating sick building syndrome-related fungi and their mycotoxins was evaluated. Filter papers (15 per organism) featuring growth of Stachybotrys chartarum, Chaetomium globosum, Penicillium chry...

Soil fumigation is commonly used to control soil-borne pathogens and weeds. Our aim was to examine the effects of soil fumigation with chloropicrin (CP) and methyl isothiocyanate (MITC) on CH4, N2O and CO2 production and emission. These effects on a SE USA forest nursery soil were examined in field and laboratory experiments. Following field fumigation, CH4 surface emissions and concentrations ...

Soil fumigation has recently been shown to affect the greenhouse gas balance by increasing emissions of nitrous oxide (N2O) following chloropicrin (CP) application. However, the exactmechanisms of this increasewere not investigated. The purpose of this study was to elucidate potential mechanisms of CP-induced N2O production through laboratory incubations using chemical inhibitors (acetylene, an...
