Most intensive care patients require frequent tracheal toilet, a procedure usually performed by suctioning the tracheal tube. Such procedures often result in the production and dissemination of droplets. We measured the distance visible droplets disseminated during tracheal tube suctioning of patients in an adult surgical intensive care unit. Fifty consecutive suction procedures in 14 patients ...

This paper presents an application of a Higher Order Shear Deformation Theory (HOST 12) to problemof free vibration simply supported symmetric and antisymmetric angle-ply composite laminated plates.The theoretical model HOST12 presented incorporates laminate deformations which account for the effectsof transverse shear deformation, normal strain/stress nonlinear variation in-planedisplacements ...

We use molecular dynamics simulations to study the structure, dynamics, and transport properties of nano-confined water between parallel graphite plates with separation distances (H) from 7 to 20 Å at different water densities with an emphasis on anisotropies generated by confinement. The behavior of the confined water phase is compared to non-confined bulk water under similar pressure and temp...

A scaling model is presented to analyze the reversible strain-hardening phenomenon in end-tethered polymer clay nanocomposites (Krishnamoorti, R.; Giannelis, E. P. Langmuir 2001, 17, 1448). It is assumed that for attractive clay-polymer interactions a fraction of the polymer chains that span the space between opposite clay plates get adsorbed on them, thereby bridging the plates. Under large am...

Thin plates are subject to several imperfections (including dents) which reduce the ultimate strength of plates. In this work, nearness effect of two short dents of same size on the ultimate strength of a thin square steel plate is numerically investigated. Dents are modeled on the FE surface of the undented plate by varying the location and orientation of dents and the centre distance between ...

The Casimir effect for parallel plates in the presence of compactified universal extra dimensions within the frame of Kaluza-Klein theory is analyzed. Having regularized and discussed the expressions of Casimir force in the limit, we show that the nature of Casimir force is repulsive if the distance between the plates is large enough and the higher-dimensional spacetime is, the greater the valu...

To mitigate the risk of wake vortex encounters during final approach, so-called plate lines have been developed. Data collected a six-month measurement campaign at Vienna International Airport are used to assess potential for reducing minimum aircraft separations facilitated by approach and landing following re-categorisation (RECAT-EU) methodology revised turbulence categorisation. ensure that...

All variable capacitance accelerometers have certain basic design elements in common. They incorporate a seismic mass whose motion in response to shock or vibration lags behind that of the accelerometer housing. The capacitor consists of two plates, one attached to the outer frame and therefore stationary and the other attached to the seismic, or inertial, mass. The value of this capacitor is a...

In this paper, the Casimir effect for parallel plates in the presence of one compactified universal extra dimension is reexamined in detail. Having regularized the expressions of Casimir force, we show that the nature of Casimir force is repulsive if the distance between the plates is large enough, which is disagree with the experimental phenomena.
