a resilient soft liner (rsl) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture's intaglio surface. use of a thermoplastic vacuum-formed template and an endodontic k-file, as guides, for the reduction of a processed mandibular complete denture to receive rsl is described in the present report. a proce...

We report results from the first mid-infrared spectroscopic study of a comprehensive sample of 33 LINERs, observed with the Spitzer Space Telescope. We compare the properties of two different LINER populations: infrared-faint LINERs, with LINER emission arising mostly in compact nuclear regions, and infrared-luminous LINERs, which often show spatially extended (non-AGN) LINER emission. We show ...

We explore the three-dimensional interaction of higher acoustic modes with bias-flow perforated liners in cylindrical and annular ducts. Pressure fluctuations in the vicinity of the liners excite the production and shedding of vorticity from the rims of apertures in the liners. An effective liner compliance is used which accounts for this transfer of acoustical into vortical energy. The investi...
