We report the discovery of an expanding cylinder HI gas radius 1 kpc and vertical extent 800 pc by analyzing 21-cm line survey data from literature. The is at 150 km s$^{-1}$ rotating 100 s$^{-1}$, interpreted as due to a high-velocity conical wind $\sim 180$ Galactic Center. total mass estimated be 8.5\times 10^5 M_\odot$ kinetic energy 3\times 10^{53}$ ergs.

Purpose. Rotating hinge knee prostheses should provide a stable situation following reconstruction. We performed a biomechanical analysis to establish the association between design of the central rotational stem (peg) and implant's stability, in a theoretical setting. Methods. Six different rotating hinge designs were tested, and three observers performed two different measurements with a cust...

Nose cones, turbine blades and bearings have rotating components and represent very practical geometries for which the modal behavior of vortex structures is not completely understood. These three rather different physical cases are being studied. A common theme of competition between modes and vortex types, whether counter-rotating or co-rotating, emerges. The objective of ongoing work is to o...

The cone–disk apparatus consists of a cone that touches the disk at its apex and is used in medical evices, viscosimeters, conical diffusers, etc. Theoretically, three-dimensional flow nanofluid gap studied for four different physical configurations. Buongiorno model, consisting thermophoresis Brownian diffusion mechanisms, to describe convective heat transport nanofluid. continuity equation, N...

a finite element analysis is presented for sloshing and impulsive motion of liquid-filled conical tanks during lateral anti-symmetric excitation. the performed analyses led to the development of a number of charts which can be used to identify the natural frequency, the mode shapes of conical tanks for both fundamental and the cos(θ)-modes of vibration. conical tank geometry was described with ...

In this paper, the buckling of non-homogeneous isotropic truncated conical shells under uniform lateral pressure and resting on a Winkler foundation is investigated. The basic relations and governing equations have been obtained for non-homogeneous truncated conical shells. The critical uniform lateral pressures of non-homogeneous isotropic truncated conical shells with or without a Winkler fou...
