A new type of riser, such as the thermoplastic composite pipe, features a low mass ratio and is becoming increasingly common in marine engineering projects. However, vortex-induced vibration (VIV) poses significant concern regarding fatigue damage risers, VIV understandings risers with ratios are still limited require further investigation. The present study conducted experimental research on flexible pipe critical 0.50 at subcritical Reynolds numbers (Re) through towing water. displacement...

In this study, we synthesized 12 monofunctional tridentate ONS-donor salicylaldimine ligand (L)-based Ru(II) complexes with general formula [(Ru(L)(p-cymene)]+·Cl– (C1-C12), characterized by 1H NMR, 13C UV, FT-IR spectroscopy, HR-ESI mass spectrometry, and single-crystal X-ray analysis showing ligand's orientation around the center. All of these were tested for their anticancer activities in multiple cancer cells. The superior antitumor efficacy C2, C8, C11 was demonstrated reduced...

An experimental apparatus for studying vortex-induced vibration (VIV) of a flexible pipe was designed and constructed in an ocean basin. A VIV test tensioned oscillatory sheared flow (OSF) performed based on this rotation rig. One end the is fixed, one forced to oscillate harmonically with various amplitudes periods. The results show that under OSF exhibits amplitude modulation hysteresis phenomena. critical Keulegan-Carpenter (KC) number proposed describe occurrence modulated OSF. provide...

A frequency capture phenomenon in which the dominant response of downstream cylinder is same as that upstream despite differences their physical characteristics was recently experimentally identified. The mechanism this investigated by flow around two cylinders with unequal diameters undergoing flow-induced vibrations (FIV) using open-source code OpenFOAM. Two FIV systems, a large stationary/vibrating and vibrating cylinder, are used for simulation. free to vibrate both in-line cross-flow...

We investigated the potential of ferric iron-modified biochar to lessen autotrophic nitrification and lower nitrous oxide (N2O) emissions in paddy soils. A 15N tracing incubation was conducted investigate changes soil gross nitrogen (N) transformations under various amendments (control, unmodified biochar, Fe-modified biochar). Acetylene 1-octyne were used assess relative contributions ammonia-oxidizing bacteria (AOB) archaea (AOA) N2O emission from soil. The increased rate NH4+...

Floating wind-aquaculture platforms are drawing increasing attention from the academic and engineering communities due to their potential fully exploit utilize marine space its resources. However, these integrate both hydrodynamics aerodynamics of floating wind turbines aquaculture cages, making mechanical properties more complex. This study aims evaluate effects three different hydrodynamic aerodynamic damping components on contribution stochastic environmental loads dynamic response a...

SUMMARY Conformal inference is a popular tool for constructing prediction intervals. We consider here the scenario of post-selection/selective conformal inference, that is, intervals are reported only individuals selected from unlabelled test data. To account multiplicity, we develop general split framework to construct selective with false coverage-statement rate control. first investigate coverage rate–adjusted method Benjamini & Yekutieli (2005) in present setting, and show it able...
