Tetraeder Geometry
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 2017, Vol 13, Issue 4
Abstract
In the same way every circle is corresponding to an equal sided triangle the 3-sphere is corresponding to an inserted tetraeder. The latitude of the corners of the tetraeder on the 3-sphere is calculated here giving the result arcsin(1/3), while arcsin(1/2) is derived for the 2-dimensional sphere.

Properties of Copper nitride thin films deposited using a pulsed hollow cathode discharge
Copper nitride (Cu3N) thin films were deposited on a glass substrates using pulsed hollow cathode discharge (PHCD). The deposition was performed at 4kV charging voltage, and nitrogen gas pressure of 10-2 torr. The struct...
The interference of two-dimensional superconducting induced current in vector potential A field
If a two-dimensional superconducting mental surface is passed through by two infinite straight magnetic flux which is shielded by superconductivity, and it was supposed that the change rate of flux was not equal to zero...
Traveling wave solutions for the Couple Boiti-Leon-Pempinelli System by using extended Jacobian elliptic function expansion method
In this work, an extended Jacobian elliptic function expansion method is pro-posed for constructing the exact solutions of nonlinear evolution equations. The validity and reliability of the method are tested by its appli...
Electro Paramagnetic Resonance and Magnetization Measurements of Metal-Substituted Hydroxyapatites Used in Hyperthermia Applications
Pure and metal doped hydroxyapatite samples nano-particles were prepared by the wet chemical method. Copper and cobalt is used in doping hydroxyapatite. Sample was prepared without change in the stoichiometric ratio of C...
Effects of MHD and wall properties on the peristaltic transport of a Carreau fluid through porous medium
This work concerns the peristaltic flow of a Carreau fluid model through porous medium under combined effects of MHD and wall properties. The assumptions of Reynolds number and long wavelength is investigated. The flow i...
