Abstract: An excavating machine includes an actuation unit for moving the excavator, a main winch and secondary winch for lifting and lowering the actuation unit. A closed hydraulic circuit or an electric circuit drives the main winch. An open hydraulic circuit drives the secondary winch. A first pressure or current sensor measures fluid pressure or, electric current intensity in the hydraulic or electric driving circuit. A second pressure sensor measures fluid pressure in the open hydraulic circuit. A pressure regulator regulates fluid pressure in the open hydraulic circuit. A control unit executes a combined operating condition with the winches applying a force simultaneously and based on values sensed, controls the pressure regulator so the fluid pressure in the open hydraulic circuit, during the combined operating condition, has a target value that is a function of: the fluid pressure in the closed hydraulic circuit or the current in the electric circuit.

Abstract: The present invention relates to a method for detecting a nucleic acid of a gut microorganism in a sample using a nucleic acid of a bacterium as an internal control nucleic acid selected from a normal gut flora, and to a composition for nucleic acid amplification used in the method. The internal control according to the present invention is present in the sample from the beginning, and thus there is no inconvenience of separately adding an internal control after the sample collection process, and may be used as an internal control for the sample collection process, an internal control for the nucleic acid extraction process, and an internal control for the nucleic acid amplification process. In addition, the presence or absence of the nucleic acid of the gut microorganism in the sample may be detected with a high accuracy through the minimization of false negative and false-positive determinations by using the nucleic acid of the bacterium as the internal control selected from the normal gut flora.
