A catheter for retrograde orientation in a blood flow is used to determine the blood flow rate by thermodilution measurements. At least some of the synthetic silica glass members composing the illumination optical system, the projection optical system and the reticle consist of synthetic silica glass members which, upon 1104 pulse irradiation with an ArF excimer laser at an energy density from 0. The method further includes transmitting the message created to respective devices of one or more intended recipients, such that, the message received on a respective device of a respective recipient notifies the respective recipient regarding the privacy and control features selected by the sender for one or more portions of data contained in the message. As the leakage emission is returned to the active medium, the low threshold current density lasing is possible. Network performance improvement attributable to the Optimal DER Portfolio is quantified in engineering and financial terms. Also provided is a shift speed correction section for correcting the shift speed for an initial downshift in the acceleration mode to a shift speed slower than the shift speed set by the shift speed setting section, only when a demanded degree of the driver’s acceleration intention is small.
