The irradiation effect of DC-DC power converter under x-ray
The irradiation response of DC-DC power converter was studied using X-ray source with whole and local irradiation method. It was indicated that the irradiation response of the different part of circuit was represented different effect. The VDMOSFET of DC-DC power converter was tremendous irradiation affected, and PWM and Shottky diode was exiguous affected, and the trend of DC-DC power converter optical-coupler parameters affected by optical-coupler was reversely with other part of DC-DC circuits.
A New Irradiation Technology—Low Energy X-ray Radiation
The mechanism of hole-trapping in oxide and interface state buidup was discussed un- 
der irradiation in this paper first, then a low energy X-ray irradiation system was introduced, final- 
ly the variety of nMOSFET threshold voltage after X-ray irradiation was studied, It is shown that 
the influence on nMOSFET threshold voltage of X-ray is correlated with that of ~(60)Co.
Studies on the composition, quality and processing of triticale. Part II. Mineral composition of grain and flour.
Mineral composition of grain and flour in 14 promising triticale strains from India are reported. The mean values for whole grain, i.e. Ca (0.47 mg/g), P (2.70 mg/g), K 4.60 mg/g, Na (352 micrograms/g), Zn (41.6 micrograms/g), Cu (7.0 micrograms/g), Fe (73.4 micrograms/g) and Mn (33.6 micrograms/g) were obtained as compared to those of flour, i.e. Ca (0.27 mg/g), P (0.97 mg/g), K (1.64 mg/g), Na (231 micrograms/g), Zn (26 micrograms/g), Cu (4.0 micrograms/g) and Mn (10.5 micrograms/g), respectively. These values were found to be considerably higher than those of wheat. Highly significant positive correlations of ash with sodium and zinc in whole grain were observed. In the case of triticale flour, highly significant positive correlations of ash with manganese, phosphorus and potassium were obtained.
