The invention further relates to pharmaceutical compositions containing the above compounds as well as a process for preparing the compounds of formula (I). The compounds of formula (I) possess antioxidant effect and therefore, they are useful for inhibiting the peroxidation of lipids occurring in mammals (including human).

    摘要： The invention relates to an apparatus for supplying high-power electric loads operated in a pulse-like manner, particularly to X-ray equipment.The apparatus makes use of the mechanical energy of rotation of a flywheel rotated through a time period which is substantially longer than the pulse duration of the load by a driving power being substantially smaller than the pulse power of the load to generate a supply voltage for the load in expense of this mechanical energy. The driving period of the flywheel and the associated moderate driving power provide an energy balance with the short pulses with high power consumption. The apparatus comprises a generator unit with at least one electric rotary machine which has a rotor that rotates together with the flywheel. The excitation of the rotary machine is provided by a field power supply being controlled by a control unit. The control unit controls the excitation of the generator unit to provide predetermined output voltage and current levels for the load.The apparatus according to the invention can provide a specified operation control for the load.According to an aspect of the invention a method has been provided for carrying out fluorography which can see to an increased sensed light intensity. According to this method fluoroscopy is carried out by pulsed X-ray irradiation with small average intensity and high pulse intensity, in which the repetition frequency of the pulse is high enough to provide for a continuous light sensation. Such pulsed irradiation provides for an image on the fluoroscopic screen in which the sensed light intensity is increased by the ratio of the peak and average radiation intensities compared to the light intensity of a conventional continuous irradiation with the average intensity.
