    摘要: A method for providing a string of tubing for installation in a well, which method comprises installing a string of tubing within a wellbore, wherein the string of tubing comprises a plurality of elongated tubular members and at least one cylindrical liner comprising a polymer; at least one of the plurality of elongated tubular members includes a cylindrical wall having an inner surface and an outer surface; the cylindrical liner has an outer surface that is disposed in adjacent contact with the inner surface of the elongated tubular member; the cylindrical liner has an inner surface that defines the tubing borehole through which fluids are capable of flowing; and the cylindrical liner has a scrolled configuration.

    摘要: The instant invention provides a method for producing RNA enzymatically in a semi-batch or continuous-flow bioreactor using a DNA template immobilized to a solid support through a linkage having a single-stranded overhang extending from a noncoding strand. The coding strand remains dissociable from the immobilized noncoding strand. The immobilized RNA template is reused in at least sixteen rounds of transcription reaction. The coding strand can be replaced with a fresh DNA strand encoding the same or a different RNA.

    摘要: A fast-acting and portable diagnostic kit for detecting diamines in biological fluids is in the form of a diamine oxidase and a chromogenic system to detect the presence of hydrogen peroxide resulting from oxidation of such diamines. The kit may especially be used to detect cadaverine or putrescine or a mixture thereof, for example in a vaginal secretion, in order to detect Gardnerella-related bacterial vaginosis.

    摘要: A process and an apparatus using an inverse discrete Fourier transform forynthesis of complex waveforms that have one or more sinusoidal components of arbitrary frequency, amplitude and phase. The component sinusoids are formed in segments of a predetermined period and modulated according to a preselected function. The modulation characteristic is compensated for by overlapped concatenation of adjacent segments.
