Study on effect of absorbent on acoustic damping of duct

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The acoustic material has been used inside ducts as a countermeasure of the self-sustained tone generated from heat exchangers and boilers. However the effects of the amount of acoustic material and its patching position in a lined duct on the acoustic ...

Response of neuroblastoma cells to RF currents as a function of the signal frequency

open access: yesBMC Cancer, 2019
Background Capacitive-resistive electric transfer (CRET) is a non-invasive therapeutic strategy that applies radiofrequency electric currents within the 400–600 kHz range to tissue repair and regeneration. Previous studies by our group have shown that 48

Programmable Nanoscale Motion via Molecular Patterning on DNA Origami

open access: yesAngewandte Chemie, EarlyView.
DNA origami nanorods enable precise urease placement with tunable coverage and asymmetry, revealing that propulsion depends on a balance of catalytic loading and geometry. Maximum speed occurs at ∼25% end‐coverage and declines as enzyme distribution becomes more symmetrical.

Study on acoustic natural frequency and its mode of one dimensional sound field partitioned by perforated plate

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Karman vortex shedding occurs when the gas passes through the duct with tube bank of the heat exchangers, such as gas heaters and boilers. Very high level sound in called “self-sustained tones” occurs due to the interference of the vortex and the sound ...
