A room-temperature diode-end-pumped acoustooptical (AO) Q-switched Tm:GdVO4 laser was firstly reported. The minimum AO Q-switch pulse width was measured to be about 48 ns with output power of 2 W and repetition rate of 5 kHz. Continuous-wave output power of 2.8 W at 1912 nm was obtained under the ab
## Abstract Cardiac MRI at 3T provides a means to increase the contrastβtoβnoise ratio (CNR) for firstβpass perfusion MRI. However, both the static magnetic field (__B__~0~) and radio frequency (RF) field (__B__~1~) variations within the heart are comparatively higher at 3T than at 1.5T. The increa
An airlift pump operating at submergence ratios between 0.2 and 0.6 and using water as the pumping liquid, has been investigated. Circular pipes of constant short length of 1 m and inner diameters of 3 and 5 cm were used as riser tubes. The water flow rate measurements for various air flow rates all
