PURPOSE To evaluate the safety and effectiveness of computed tomography (CT)-guided radiofrequency (RF) ablation in the palliative treatment of recurrent advanced head and neck cancers. MATERIALS AND METHODS From November 2002 to January 2005, the authors identified 14 patients (median age, 61 years) with 14 recurrent advanced primary head and neck malignancies who underwent 27 CT-guided RF a...

Thermal 15 was drilled in November, 1983, to a TD of 700 feet. A steam entry encountered at 490 feet was found to communicate with the highpermeability upflow zone of the Thermal Shallow Reservoir. A low-flowrate, higher-pressure steam entry at 600 feet was not detected while drilling but was indicated during a subsequent spinner survey. The pressure, flowrate, and enthalpy of the five wells co...

In the present work, detailed studies of 2D TVC are investigated by using both experimental and numerical methods. For an active cavity flow case, the present results reveal that the pressure drop value across the combustor increases with the mainstream Reynolds number (Rems) due to the higher velocity gradient between the cavity and mainstream flow. Experimental results indicate that the norma...

Little empirical research has investigated how players identify with video game characters. In this paper, I use data from interviews with video game players who are members of marginalized groups, to interrogate the links made between how players identify with video game characters and the importance of representation. I discuss how games‟ ludic, bodily and socially interactive aspects result ...

In this paper we consider some nonlinear discrete-time dynamic models proposed in the literature to represent marketing competition, and we use these models to critically discuss the statement, often made in economic literature, that identical agents behave identically and quasi-identical ones behave in a similar way. We show, through examples and some general mathematical statements, that the ...

The three-dimensional uniformly frustrated XY model is simulated to search for a predicted ‘‘vortex loop’’ transition within the vortex line liquid phase of a strongly type-II superconductor in an applied magnetic field. Results are shown to strongly depend on the precise scheme used to trace out vortex line paths. While we find evidence for a transverse vortex path percolation transition, no s...

We report 4.5 μm luminosities for 27 nearby (D . 5 Mpc) dwarf irregular galaxies measured with the Spitzer Infrared Array Camera. We have constructed the 4.5 μm luminosity-metallicity (L–Z) relation for 25 dwarf galaxies with secure distance and interstellar medium oxygen abundance measurements. The 4.5 μm L–Z relation is 12+log(O/H) = (5.78 ± 0.21) + (−0.122 ± 0.012) M[4.5], where M[4.5] is th...
