The results indicated that the degree of grafting increased with increasing monomer concentration and dose and decreased with increasing concentration of CuSO4. Contact angle of the grafted membranes surface decreased with the dose.
The main results are list as followed:(1) The effects of varying concentrations of MMH, HEH, AHA, HNO3, UO22+ and Fe3+on radiolysis behavior of MMH, HEH, AHA at the absorbed dose of 50 kGy have been studied in detail.
The γ radiation dose rate in the environment, the content of 238 U and 226 Ra in the ambient soil and the farmland downwind, the concentrations of 238 U , 232 Th, 226 Ra, 40 K and 222 Rn aswell as α potential energy in air, and the concentrations of natural U and Th in effluent are higher than on the contrast points.
结果表明：电厂周围环境γ辐射剂量率水平，环境土壤和下游农田土壤中238U、226 Ra 含量，环境大气中238 U、232Th、226 Ra、40 K、222Rn 浓度及α潜能值，排出水中天然铀和钍的浓度等均比对照点有升高；
While a trace amount of Cu was co-doped into MgSO 4:Dy,P the TL glow peak at 352.7 ℃ was suppressed and the TL sensitivity and the nonlinearity of dose response for the main dosimetric peak at 283.6℃critically depends on the concentration of dopant Cu.
TW-NAOCAS could give the following information within 30 minutes: wind field in assessed area(near area: 20×20 km~2,space resolution 500 m;far area: 80×80 km~2,space resolution 4 km); concentration,prediction dose,evitable dose of sheltering and evacuation,etc. for various released nuclides in each reseau.
The absorbed dose of irradiationbeing up to 10~9rad,the properties of bituminized product were significantlychanged,the leach rate of sodium ion was5×10~(-3)gm cm~(-2)d~(-1)whichwas about 50 times more than that of unirradiated product and the rate ofH_2 released was 3.69 1/Kg.
Studies in rats revealed dose dependency/ non-linearity in arteether pharmacokinetics with in the dose levels used.
In this study, we find that prodigiosin could effectively inhibit the proliferation of human pancreatic cancer cells H8898 in a dose-and-time-dependent manner, with an IC50 of 75μmol according to the results of MTT and cell proliferation assays.
Prodigiosin may effectively enter cells and promote the level of intracellular reactive oxygen species (ROSin) in a dose-dependent manner.
Doses ranging from 12.5-50 μM provided a dose-dependent reduction in the number of viable cells when compared to controls.
At the 50 μM dose, the number of viable cells was reduced by 65% suggesting potential antineoplastic effects of 9-O-methylfusarubin.
