Reactor Pressure Vessel Nozzle Inner-Radius Examination
Volume 5: High-Pressure Technology; ASME NDE Division; Rudy Scavuzzo Student Paper Symposium, 2013Reactor pressure vessel nozzle inner radius (NIR) areas are identified as a specific target for ultrasound examination (UT) by many regulatory codes. This region represents a particularly challenging geometry to examine. Typically the examination is performed from inside the vessel with at least the upper internals removed.

Converging swirling liquid jets from pressure swirl atomizers: Effect of inner air pressure
Physics of Fluids, 2002Converging swirling liquid jets from pressure swirl atomizers injected into atmospheric air are studied experimentally using still and cine photographic techniques in the context of liquid–liquid coaxial swirl atomizers used in liquid rocket engines. The jet exhibits several interesting flow features in contrast to the nonswirling liquid jets (annular ...

Effect of increased inner ear pressure on middle ear mechanics☆☆☆★
Otolaryngology - Head and Neck Surgery, 1998Velocity of malleus, umbo, and stapes footplate in response to stepwise increases up to +400 mm H2O in hydrostatic pressure of the inner ear was investigated in 10 fresh human temporal bones by using a laser Doppler interferometer. The sound‐pressure input was 114 dB SPL, and the frequency range was 0.4 to 5.0 kHz.

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.

Electrolytes and Osmotic Pressure in Inner Ear Fluids
Practica Oto-Rhino-Laryngologica, 1983From chemical analyses of inner ear fluids, it was found that the sum concentration of electrolytes (Na+K+Cl) is higher in the endolymph than in the perilymph and that the perilymph contains a higher concentration of glucose and protein compared to the endolymph.

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.

Dynamics of Inner Ear Pressure Change Caused by Intracranial Pressure Manipulation in the Guinea Pig
Acta Oto-Laryngologica, 2001Previous studies have shown that pressure changes in the cerebrospinal fluid compartment are transmitted to the inner ear. The main route for pressure transfer is the cochlear aqueduct. about which little is known with regard to its dynamic properties.

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.

Change of Guinea Pig Inner Ear Pressure by Square Wave Middle Ear Cavity Pressure Variation
Acta Oto-Laryngologica, 2002The 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" function did not fit well and therefore more complicated functions were used for this purpose. For

Uncompacted Inner Myelin Lamellae in Inherited Tendency to Pressure Palsy
Journal of Neuropathology and Experimental Neurology, 1991Nerves in patients with inherited tendency to pressure palsy (ITPP) are susceptible to degrees of traction or compression which in nonaffected persons do not induce neuropathic symptoms or deficits, conduction block of fibers, or electromyographic changes characteristic of the disorder.
