Abstract During the Deepwater Horizon (DwH) oil spill, an excessive production of marine snow was observed, and it estimated that as much 14% transferred to ocean floor by MOSSFA (Marine Oil Snow Sedimentation Flocculent Accumulation). is important pathway transferring floor. We performed experiments at laboratory scale in 15 aquaria, representing 5 exposures with or without oil, only controls ...

Tropical forest canopies are among the most species-rich terrestrial habitats on earth and one of the remaining relatively unexplored biotic frontiers. Epiphytic bromeliads provide microhabitat for a high diversity of organisms in tropical forest canopies and are considered a keystone resource. A number of amphibians inhabit these phytotelmata, yet their ecological role and status in forest can...

Oil tank level is an important control parameter in oil depot management. According to the principle that liquid can absorb guided wave propagation energy wall, this paper studied a non-reference detection method of external ultrasonic switch based on signal change value between current and previously signal. The experimental results show with center frequency 30 kHz sensitive low misjudgment d...

This paper presents an experimental study on a single tank thermal energy storage (TES) system integrated with cooking unit. The had capacity of 45 L oil. chamber was embedded in the tank, thereby eliminating use pumps and connecting pipes between unit designed to make good physical contact, circumferential basally, pot, improve rate heat transfer. Experimental tests were performed oil only oil...

This paper presents a numerical calculation method that allows for the simulation of mechanical and acoustic behaviour transformer tank. In order to simulate vibroacoustic an oil-immersed power transformer, acoustic-mechanical coupled three-dimensional finite-element model was setup. The is performed in frequency domain at frequencies adjacent driving frequency. A vibration source closely resem...

Tanks, as instruments in oil and its product’s amount measurement system chain, must be regularly maintained metrologically inspected, they significantly contribute to uncertainty. However, when measuring a change the of stored material (i.e., transfer), uncertainty becomes highly dependent not only on mass transaction but also initial liquid level tank. This paper provides modeling uncertainti...
