INFLUENCE OF THE TRANSDUCER-MOUNTING METHOD ON THE RADIATION PERFORMANCE OF ACOUSTIC SOURCES USED IN MONOPOLE ACOUSTIC LOGGING WHILE DRILLING

Influence of the Transducer-Mounting Method on the Radiation Performance of Acoustic Sources Used in Monopole Acoustic Logging While Drilling

Transducers used in acoustic logging while drilling (ALWD) must be mounted on a drill collar, and their radiation performance is dependent on the employed mounting method.Herein, the complex transmitting voltage response of a while-drilling (WD) monopole acoustic source was calculated through ultrastar dc hc550 finite-element harmonic-response anal

Effects of Stocking Density on the Survival, Growth, and Stress Levels of the Juvenile Lined Seahorse (Hippocampus erectus) in Recirculating Aquaculture Systems

Seahorses are increasingly regarded as a promising farming object suitable for recirculating aquaculture systems (RASs) due to their high economic value.However, reports on the large-scale farming of ultrastar dc hc550 seahorses in RASs are rare, and some key parameters, such as stocking densities, are still unclear.In the present study, we employe
