PD Defect Monitoring for Oil-Impregnated Paper Bushing by Measuring the Inner Pressure
IEEE Access, 2019 When the inner insulation of oil-impregnated paper bushing breaks down in service, gases decomposed by oil and paper may cause an explosion. The explosion of bushing occurs from time to time because of the lack of an effective monitoring method. In order

Change of Guinea Pig Inner Ear Pressure by Square Wave Middle Ear Cavity Pressure Variation
Acta Oto-Laryngologica, 2002 The inner ear fluid pressure of guinea pigs was measured during square wave middle ear cavity pressure variation. Time constants were derived for the slopes of the inner ear pressure recovery curves after middle ear pressure change. A "single exponential"

Inner-pressure Ratio Adjustment of the Twin-screw Compressor in a High-temperature Heat Pump
Zhileng xuebao, 2017 Changing the working conditions of an industrial heat pump can cause a mismatch of the inner and outer pressure ratios of the twin-screw compressor. Over-compression and under-compression increase the compressor power consumption and decrease the heat ...

Inner ear tissue preservation by rapid freezing: Improving fixation by high-pressure freezing and hybrid methods. [PDF]
, 2014 In the preservation of tissues in as 'close to life' state as possible, rapid freeze fixation has many benefits over conventional chemical fixation. One technique by which rapid freeze-fixation can be achieved, high pressure freezing (HPF), has been ...

Thermoelasticity of Hexagonal Close-Packed Iron from the Phonon Density of States [PDF]
, 2012 Iron is the main constituent in Earth’s core, along with ~5 to 10 wt% Ni and some light elements (e.g., H, C, O, Si, S). This thesis explores the vibrational thermodynamic and thermoelastic properties of pure hexagonal close-packed iron (ε-Fe), in an ...

Pressure-driven wrinkling of soft inner-lined tubes
New Journal of Physics, 2022 A simple equation modelling an inextensible elastic lining of an inner-lined tube subject to an imposed pressure difference is derived from a consideration of the idealised elastic properties of the lining and the pressure and soft-substrate forces.
