hollow sphere
The thermoelastic dynamic solution of a multilayered spherically isotropic hollow sphere in the state of spherical symmetry is obtained.
      
The present method is suitable for a multilayered spherically isotropic hollow sphere consisting of arbitrary layers and subjected to arbitrary spherically symmetric thermal loads.
      
The axisymmetric streaming Stokes flow past a hollow boundary of arc cross-section leads to a mixed boundary value problem that has only been solved for a hollow sphere with equal caps removed.
      
A relative or reciprocal calibration method was used to calibrate the hollow sphere hydrophone.
      
A special attachment was used to fix the hollow sphere hydrophone in a vertical orientation to the source transducer.
      
As a clinical application, a catheter could implant the hollow sphere transducer directly inside the tumor tissue for thermal therapy.
      
Comparison of the predicted radiation flux at the outside hollow sphere boundary with theory for a gray emitting media with unity radiation power.
      
Center nodal vertical displacement versus time for solid sphere pressed into hollow sphere.
      
During cell culture studies, a single lumenal epithelial cell divides to form a hollow sphere known as an acinus.
      
Each hollow sphere was placed at the focus of the source transducer to study its response.
      
Earth as a hollow sphere was preferred, being closest to the description of Earth in Lakota mythology.
      
For example, a knotted solid torus has the same genus as a simple torus, or a hollow sphere as two spheres.
      
Hollow sphere whose internal surface is a diffuse reflector that is as non-selective as possible.
      
However, in conjunction with fiber and hollow sphere incorporation into the aluminum deposit, anode compartmenting did have advantages.
      
In vitro experiments have shown good transmitting characteristics using the hollow sphere transducers as a minimally invasive ablation device.
      
In a Babbington nebulizer, fluid is dripped over a pressurized stream of gas that emerges from a slit in a hollow sphere.
      
In addition, the results show that the increase of hollow sphere curvature at a given optical thickness has less radiation loss.
      
No fractured hollow sphere was found, which further confirmed that the spheres have solid structures.
      
This thin wire is also used to position the inner ball in the middle of the hollow sphere.
