    摘要: The invention relates to NAD(P)H-dependent nitrate reductase from yeasts, to a process for the preparation thereof and to the use thereof in a reagent for determining nitrate. The nitrate reductase is characterized by a molecular weight of about 350 000 D and can be obtained by yeast cells which have been cultivated in a completely synthetic nutrient medium with nitrate as the sole nitrogen source and which contain nitrate reductase being disrupted in phosphate buffer, the crude extract being chromatographed on an anion exchanger, the fractions containing nitrate reductase being mixed with protein, concentrated by ultrafiltration and dried by fluidized bed granulation. The reagent for determining nitrate contains, besides the nitrate reductase prepared in this way, also NAD(P)H and a color reagent for determining nitrite.

    摘要: The invention relates to a high-frequency surgical apparatus in which, for the purpose of cutting and/or coagulating biological tissue by means of high-frequency current, a high-frequency generator having a first electrode and a second electrode forms a high-frequency circuit through the tissue being treated, with an electric arc being formed, said apparatus having a measuring device to detect DC voltage components forming in the high frequency circuit when the arc is formed, said DC voltage components being usable for controlling the high-frequency generator via a controlling device. The invention is characterized in that the measuring device has an arc-decoupling circuit which separates the DC voltage components in the positive half-cycle of the high-frequency AC voltage from the DC voltage components in the negative half-cycle of the high-frequency AC voltage and makes available at least one of the separated DC voltage components as a signal for subsequent processing in the controlling device. The invention also relates to a corresponding method of running such apparatus.

    摘要: A negative-working lithographic printing plate precursor is used for making lithographic printing plates from infrared radiation imaging. The precursor comprises free radical chemistry and a specific infrared radiation absorber that is a cyanine dye and defined by Formula (1a) described in the disclosure. This particular infrared radiation absorber provides both IR sensitivity and print out after imaging.
