Granted: 2017-02-07
Abstract: The present invention relates to a method for controlling and/or regulating a metering pump having a drive motor having a shaft driven by the motor, and a displacement member disposed in a metering head, wherein the rotary motion of the shaft is converted into an oscillating motion of the displacement member, wherein the displacement member interacts with an outlet and inlet valve, leading to a pump stroke (pressure stroke) and an intake stroke and thus to delivering a metered medium. In order to disclose a method for controlling and/or regulating a metering pump operating principally without a position sensor on the pushrod, and that can highly precisely determine the metering behavior of the pump, according to the invention at least one motor operating parameter, preferably a motor voltage U or a motor current I, is measured, at least one control parameter is calculated from the measured motor operating parameters and optionally further known motor characteristics are calculated, the at least one control parameter is compared to a predetermined guide parameter, and a comparison signal depending on the result of the comparison is output and can be used as a status, actuating, and/or regulating signal.

Abstract: The invention provides a set of nucleotides against HIV infection and their application for treatment and prevention of AIDS. The sequences of the nucleotides were shown in the sequences table. The invention was superior to the similar technology as following: High conserved RNA sequences were obtained by compare all the published HIV genome sequences. Double strand RNA sequences derived from the sequences can effectively inhibit the expression of target HIV gene. HIV gene expression can also be inhibited by double strand hairpin-like RNA transcribed in the cells harboring recombinant plasmid which contain the DNA sequences encoding the RNA sequences. Further, HIV gene expression can be knocked down by in cell transcribed double strand RNA corresponding to the RNA sequences encoded by recombinant adenovirus associated virus.
