The effect of dynamic wetting pressure on contact angle measurements

Journal of Colloid and Interface Science, 2022
The drop deposition technique can impact contact angle measurements. We hypothesized that the drop pinch-off, during the traditionally used pendant drop technique, significantly alters the static contact angle. The capillary waves and dynamic wetting pressure generated during the pendant drop deposition are the source for forced spreading, which can be

Relationships among systemic blood pressure, intraocular pressure, and open-angle glaucoma

Canadian Journal of Ophthalmology, 2008
Several vascular factors, including systemic hypertension (or high blood pressure [HBP]), ocular perfusion pressure, and nocturnal hypotension, have been identified as risk factors for the development and progression of glaucoma. The results of epidemiologic studies of these factors and their relationships to intraocular pressure (IOP) and open-angle ...

Pressure Dependence of the Contact Angle

The Journal of Physical Chemistry B, 2007
When a liquid and its vapor contact a smooth, homogeneous surface, Gibbsian thermodynamics indicates that the contact angle depends on the pressure at the three-phase line of an isothermal system. When a recently proposed adsorption isotherm for a solid-vapor interface is combined with the equilibrium conditions and the system is assumed to be in a ...

The effect of glottal angle on intraglottal pressure

The Journal of the Acoustical Society of America, 2006
Intraglottal pressure distributions depend upon glottal shape, size, and diameter. This study reports the effects of varying glottal angle on intraglottal and transglottal pressures using a three-dimensional Plexiglas™ model with a glottis having nine symmetric glottal angles and a constant minimal glottal diameter of 0.06cm.

Pressure-Scaling of Pressure-Swirl Atomizer Cone Angles

Journal of Engineering for Gas Turbines and Power, 2006
An experimental investigation was conducted to study the effects of increased ambient pressure (up to 6.89MPa) and increased nozzle pressure drop (up to 2.8MPa) on the cone angles for sprays produced by pressure-swirl atomizers having varying amounts of initial swirl.

Incident Open-angle Glaucoma and Intraocular Pressure

Ophthalmology, 2007
To evaluate the role of baseline intraocular pressure (b-IOP) as a risk factor for incident open-angle glaucoma (OAG) in participants of African origin from the Barbados Eye Studies.Population-based 9-year cohort study.Three thousand two hundred twenty-two persons examined during the study period who were free of glaucoma at baseline and at risk of ...

The Benefit of High Pressure Angle Gears VS Low Pressure Angle Gears

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">There is a trend in the industry to make gears with a profile contact ratio greater than 2.0. The main reason is that these gears would run quieter by constantly having two or more teeth sharing the load. In order to obtain a profile contact ratio greater than 2.0, it is necessary to meet two requirements:</div ...
