    摘要: A device for determining and/or monitoring the volume, and/or mass, flow of a medium flowing through a containment in a stream direction. The device includes: At least one ultrasonic transducer, which emits and/or receives ultrasonic measuring signals; and a control/evaluation unit, which determines the volume, and/or mass, flow of the medium in the containment on the basis of the ultrasonic measuring signals according to the travel time difference principle or the Doppler principle. A first clock-pulse generator having a first pulse rate and a second clock-pulse generator having a second pulse rate are provided, with the first pulse rate of the first clock-pulse generator being greater than the second pulse rate of the second clock-pulse generator. The control/evaluation unit operates the first clock-pulse generator intermittently. The control/evaluation unit sizes the duration of a switch-on, or measuring, phase and/or a resting phase as a function of the available energy.

    摘要: The invention relates to a method of a mass-spectrometric analysis of known mutation sites in the genome, such as single nucleotide polymorphisms (SNPs), using the method of restricted primer extension. The invention consists of the use of primers with a photocleavable linker. The linker creates a gap in a DNA strand which is almost the same size as a natural DNA building block (nucleoside). The linker forms a bridge over a base pair without inhibiting hybridization or enzymatic extension. However, the linker allows the primers to be cleaved after extension in order to obtain short DNA fragments which can be more easily detected on the mass spectrometer.
