A plastic catheter mount.
Among the disadvantages of catheter mounts in common use is that, as generally manufactured, they have sharp interior angles militating against laminar flow. The diagram illustrates the longitudinal section of a plastic variant in which the narrowing has been chamfered off. It has been found satisfactory in practice, and seems to be standing up robustly to use. It has the additional advantage o...
متن کاملKink scaling functions in 2D non–integrable quantum field theories
We determine the semiclassical energy levels for the φ field theory in the broken symmetry phase on a 2D cylindrical geometry with antiperiodic boundary conditions by quantizing the appropriate finite–volume kink solutions. The analytic form of the kink scaling functions for arbitrary size of the system allows us to describe the flow between the twisted sector of c = 1 CFT in the UV region and ...
متن کاملOptical kinks and kink-kink and kink-pulse interactions in resonant two-level media
An optical kink is a shock-wave-like field structure which can appear in a resonant two-level medium as a result of the nonlinear process of self-steepening. We numerically simulate this process using an adiabatically switching waveform as an input and confirm the self-similarity of resulting kinks. The analysis is also applicable to a more general waveform with a decaying trailing edge which w...
متن کاملConquering Mount Fuji: Resolution of Tension Pneumocephalus with a Foley Urinary Catheter
Tension pneumocephalus is the presence of air or gas in the cranium that is under pressure. It occurs due to disruption of the skull, including trauma to the head or face, after neurosurgical procedures and occasionally, spontaneously (Schirmer et al., 2010). Patients typically present with headache but can also have neurological deficits such as decreased mental status, numbness, and weakness ...
متن کاملSurface lattice kink solitons.
We predict theoretically that surface of an optical lattice imprinted in defocusing nonlinear media can support shock, or kink waves. Such new surface waves contain a modulationally stable pedestal and are strongly localized at the edge of the optical lattice due to Bragg-type reflection. The kink steepness and localization degree can be controlled by the lattice depth. We found two types of ki...
