Full text: HTML (1 KB)  PDF  (193 KB)  ( 660 )
Abstract ( 492 )
The radioactive concentrations of 137Cs source and other man-made radionuclides are important data for estimating environment radiation level in nuclear emergence. In order to extract the data of energy peak of 137Cs from full spectra measured by NaI(Tl) airborne gamma-ray spectrometer (GR-820), the overlapped peaks at lower energy bands are deconvolved by Gauss function fitting by least square (single peak and double peaks). The maximum relative error of single peak area is less than ±15% due to only uranium, thorium or cesium sources. And the average relative error of overlapping peak (double peaks) is 21.84%, which are produced by uranium and cesium sources. A research of deconvolving overlapped peaks of more than three peaks is needed.

Full text: HTML (1 KB)  PDF  (213 KB)  ( 191 )
Abstract ( 508 )
To produce human epidermal growth factor (hEGF) in transgenic mini-tomatoes, plasmids p2300-2A11-hEGF carrying the hEGF gene were constructed and transformed via eletro-perforation to Agrobacterium C58, and then transfected to tomatoes cg2001-14 via leaf disk transformation. The regenerated plantlets were obtained from the cotyledons after shoot and root inducing cultivations. The PCR analysis showed that the hEGF gene has been integrated into the mini-tomato genome. Radioimmunoassay (RIA) showed that the mean yield of rhEGF in the fresh fruits of the transgenic mini-tomatoes amounted to 3.85 ± 0.86 ng /g fruit. Ingestion via gastric intubation of the transgenic mini-tomato juice significantly protected the mice from the alcohol-induced acute peptic ulceration. The ulcer index, expressed as a degree of the stomach lesion, decreased from 52.20±23.24 to 21.20±6.84,and the inhibition rate got to 59.39%.

Abstract ( 1304 )
Interannual variability of landfall typhoon and the tropical cyclone formed in the western Pacific, including South China Sea is reviewed. On the basis of data over the past 35 years, the analysis suggests that the number of typhoon and tropical cyclone occurred in these regions shows a decreasing trend. The number of landfall tropical storms exhibits a similar decreasing manner; however, the landing typhoons (the maximum wind speed greater than 32.7 m/s) show an increasing trend over the past 35 years. The tropical storms occurred more frequently during July to October, accounting for 71%, while the landfall counterparts mainly happened during July to September, accounting for 78% of the total. The landfall typhoon could frequently attack China, affects large domain, and results in severe disasters according to the assessment of typhoon and it caused disasters.

Full text: HTML (1 KB)  PDF  (295 KB)  ( 538 )
Abstract ( 452 )
In this study, Na-mordenite was used as an adsorbent for the aim of removing Cu(Ⅱ) ions from the aqueous solutions, and the effects of contact time, temperature, initial metal ion concentrations, initial solution pH, adsorbent dosage and ionic strength in the adsorption process were investigated in detail. Experimental results showed that the sorption process follows pseudo-second-order kinetics very well, the correlation coefficients R2 all reached 0.999, and the rate constant of this kinetics model for the adsorption processes, k2, increased with the increasing temperatures. The isothermal data could be well described by the Langmuir, Freundlich, Dubinin-Radushkevich(D-R) adsorption isothermal equations. The thermodynamic parameter, △G°<0, was negative, indicating that the nature of adsorption process is spontaneous, △H°>0 being positive, showing the endothermic nature of the adsorption process. This adsorption processes were dominated by the ion exchange. The amount of adsorbe...更多d copper ions increased with the increasing initial metal ion concentration and solution pH in the examined range, but decreased with the increasing dosage of adsorbent and ionic strength.
