BACKGROUND For many long standing practices, the rationale for them is often lost as time passes. This is the situation with respect to the storage and handling of equimolar 50% nitrous oxide and 50% oxygen volume/volume (v/v) mixtures. METHODS A review was undertaken of existing literature to examine the developmental history of nitrous oxide and oxygen mixtures for anesthesia and analgesia ...

multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...

We consider the Rayleigh-Taylor instability problem of two initially stationary immiscible viscous fluids positioned with the denser above the less dense in a finite circular cylinder such that their starting fluid-fluid interface is the horizontal midplane of the cylinder. The ensuing linear instability problem has a 5D parameter space defined by the density ratio, the viscosity ratio, the cyl...

А new closed-loop solution for the coupled nonstationary problem of thermoelectric elasticity is designed a long piezoceramic radially polarized cylinder. The case load acting on its inner cylindrical surface considered as function temperature change at given law convection heat exchange outer face wall (boundary conditions conductivity 1st and 3rd types). Electrodynamic cylinder surfaces are c...

1. Introduction. In this article, we study the interaction between a infinitely long cylinder coated with a sheath of an elastic material and a compressible, inviscid fluid, with lubricated contact on the interface. The problem is thus posed in
