Pressure freezing of the Earth's inner core
Physics of the Earth and Planetary Interiors, 1985Abstract In an earlier paper (Fearn and Loper), it was shown that secular cooling of a completely molten iron-poor core cannot account for the presence of the Earth's solid inner core. Here, we investigate an alternative; that at least part of the inner core formed very early in the history of the Earth, during the accretion/differentiation process ...

Resonant Pressure Transmission To The Inner Ear
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991, 2005Engineering analysis of pressures in fluid-filled ducts and cavities is applied to the vertebrate inner ear. The human endolymphatic duct and combined utricle and saccule exhibit resonance in the auditory frequency range. The analysis can be used to develop more complex models of pressure transmission in inner ear ducts and cavites.

Water under inner pressure: A dielectric spectroscopy study
Physical Review E, 2014Water is the most studied substance on Earth. However, it is not completely understood why its structural and dynamical properties give rise to some anomalous behaviors. Some of them emerge when experiments at low temperatures and/or high pressures are performed.

Modulation of inner ear pressure in experimental endolymphatic hydrops
Otolaryngology–Head and Neck Surgery, 1995Physiologic study of the guinea pig model of endolymphatic hydrops has been used to better understand the manifestations of Meniere's disease. Quantitative vestibular function testing demonstrates some changes in the hydrops subjects, especially if an additional stress such as postural inversion is imposed. Understanding the hydrodynamic changes on the

Effects of Middle Ear Pressure on the Inner Ear
Acta Oto-Laryngologica, 1977It was demonstrated in experiments on normal subjects that moderate ambient pressure changes, creating overpressure in the middle ear, may induce a vestibular reaction. In other experiments on subjects suffering from acute attacks of Meniere's disease, relief of symptoms was achieved by means of ambient pressure changes of the same magnitude.

The effect of blood pressure on inner ear blood flow
Archives of Oto-Rhino-Laryngology, 1984We investigated the effects of blood pressure on the blood flow in the inner ear as compared with other organs in normotensive rats (NR), spontaneously hypertensive rats (SHR) and renal hypertensive rats (RHR). The cardiac output and the regional blood flow were measured by a radioactive microsphere technique in conscious rats. The haemodynamics of the

Determining the optimal inner air cell pressure for the effective reduction of interface pressure
Journal of Tissue Viability, 2012Alternating-pressure air mattresses can reduce interface pressure and prevent pressure ulcer development. However, bottoming out sometimes occurs, resulting in an increase in interface pressure. Therefore, optimal settings should be determined based on interface pressures and inner air cell pressures.

Hydrostatic Pressure in the Inner Ear Fluid Compartments and its Effects on Inner Ear Function
Acta Oto-Laryngologica, 1993The present study summarizes the experimental findings obtained on the pressure in the inner ear fluids and on the effects of pressure changes on cochlear function in the guinea pig. Two types of pressures have to be distinguished in the inner ear fluid compartments: (i) hydrostatic fluid pressure and (ii) superimposed hydrodynamic high frequency ...

Inner-shell chemistry under high pressure
Japanese Journal of Applied Physics, 2017Chemistry at ambient conditions has implicit boundaries rooted in the atomic shell structure: the inner-shell electrons and the unoccupied outer-shell orbitals do not contribute as the major component to chemical reactions and in chemical bonds. These general rules govern our understanding of chemical structures and reactions.

Inner and Outer Cracks in Internally Pressurized Cylinders
Journal of Pressure Vessel Technology, 1977Stress intensity factors of pressurized surface cracks at the internal surface and un-pressurized surface cracks at the external surface of an internally pressurized cylinder are estimated from stress intensity factors of a semi-elliptical crack in a finite-thickness flat plate.
