Experiments of flue gas treatment by electron beam were carried out, using simulated lignite-burning flue gas containing SO
(5500ppm), NO(390ppm) and HO(22%). Removal efficiency of SO was more than 90% at a dose of 1-2kGy. It shows applicability of electron beam for treatment of lignite-burning flue gas. Another removal reaction besides the radiation-induced radical reaction and the thermal reaction occurring without irradiation was suggested by the facts that removal of SO by the radical reaction is only a few hundreds of ppm and the removal amounts by thermal reaction under irradiation is lower than a half of total desulfurization. The mechanism similar to thermal reaction was proposed, assuming simultaneous uptake reaction of SO and NH
on the surface of liquid aerosol. It was suggested that ammonium nitrate having deliquescence relative humidity(DRH) of 60% at 25
plays an important role in producing liquid aerosols. Decrease of DRH of ammonium nitrate with increasing temperature and with formation of double salt of ammonium sulfate results in enhancement of formation of liquid aerosols.

Times Cited Count：2 Percentile：25.13(Engineering, Chemical)The continuous gas monitoring system using the mass filter (CGM-MS) was developed for the measurement of gaseous substances in air under atmospheric pressure. A capillary tube introduces the gases under atmospheric pressure into a mass filter installed in a vacuum chamber. The CGM-MS detected gaseous substances, such as sulfur dioxide, benzene and chlorobenzene, with detectable sensitivity of 0.7-1 ppmv. The monitoring system was also applied for the analysis of the products formed in electron beam irradiation of trichloroethylene (TCE) and air mixture. Dichloroacetyl chloride, carbonyl chloride (COCl), and chlorine (Cl) were quantitatively analyzed. Trichloroethylene and the products were oxidized and completely converted into carbon dioxide, Cl, and hydrochloric acid at 15 kGy. Carbonyl chloride is dissolved in an alkaline solution to be automatically oxidized into CO
and Cl
. The combination of the irradiation and the dissolution of the irradiated gas decreased to 7 from 15 kGy for the complete oxidation of TCE and the products.

Times Cited Count：16 Percentile：36.85(Plant Sciences)[C]Methionine ([C]Met) was supplied through barley roots and the C signal was follwoed using a real-time imaging system (PETIS), with subsequent development of autoradiographic images of the whole plant. In all cases, [C]Met was first translocated to the discrimination center, and this part was strongly labeled. Met absorbed by roots of the plants was subsequently translocated to other parts of the plant. In Fe-deficient (-Fe) barley plants, a drastic reduction in [C]Met translocation from the roots to the shoot was observed, while a greater amount of C was found in the leaves of Fe-sufficient or Met-pretreated -Fe plants. Treatment of -Fe plants with amiooxyacetic acid increased the translocation of [C]Met to the shoot. The retention of exogenously supplied [C]Met in the roots of -Fe barley indicates that the Met is used in the biosynthesis of mugineic acid (MA) in barley roots. This and the absence of Met movement from shoots to the roots suggest that the MA phytosiderophores precursor Met originates in the roots of plants.

Times Cited Count：16 Percentile：73.21(Chemistry, Analytical)We present real time Vanadate (V
) uptake imaging in a cowpea plant by Positron Emitting Tracer Imaging System (PETIS). Vanadium-48 was produced by bombarding a Sc foil target with 50 MeV 
-particles at Takasaki Ion accelerators for Advanced Radiation Application (TIARA) AVF cyclotron. Then 
V was added to the culture solution to investigate the V distribution in a cowpea plant. The real time uptake of the V was monitored by PETIS. We measured the distribution of V in a whole plant after 3, 6 and 20 hours of V treatment by Bio-imaging Analyzer System (BAS). After the 20 hour treatment, vanadate was detected at the up-ground part of the plant. To know the effect of V uptake on plant activity, F-labeled water uptake was analyzed by PETIS. When a cowpea plant was treated with V for 20 hours before F-labeled water uptake experiment, the total amount of F-labeled water absorption was drastically desreased. Results suggest the inhibition of water uptake was mainly caused by the vanadate already moved to the up-ground part of the plant.
