We evaluated a chamber and nose cone method of isoflurane delivery for anesthetizing eastern gray squirrels (Sciurus carolinensis; summer n 1⁄4 43, winter n 1⁄4 48) and Allegheny woodrats (Neotoma magister; summer n 1⁄4 24, winter n 1⁄4 13) for use when pain or stress was possible from sampling procedures. Mean induction time for squirrels (from beginning of isoflurane administration to safe re...

In this paper, the physical optics method is used to study the problem of electromagnetic scattering from Haack series nose cone. First, a meshing scheme is introduced which approximates the curvature of the surface by piecewise linear functions in both axial and rotational directions. This results in planar quadrilateral patches and enables efficient determination of the illuminated region and...

A high-order shock-fitting method with thermochemcial nonequilibrium and finite rate boundary conditions for graphite ablation is presented. The method is suitable for direct numerical simulation of boundary layer stability with graphite ablation. Validation with three computational data sets and one set of experimental data is shown. Stability results of the method for a 7 half angle blunt con...

A longitudinal stage separation (LSS) scheme for a parallel-arrangement two-stage-to-orbit (TSTO) vehicle is proposed and analyzed in detail, which the orbiter moves along upper surface of booster. TSTO concept comprising waverider spaceplane was designed to numerically investigate dynamic characteristics LSS at Mach 7. The influence spike models assembled nose on different angles attack (AoA) ...

For a plane electromagnetic wave at nose-on incidence on a semi-infinite perfectly conducting cone expressions for the surface field components are obtained. These have been programmed for numerical computation and data are presented for the magnitudes and phases as functions of the distance from the tip for three different cone angles. Comparison with results derived from the physical optics a...
