Slag Wool

A kind of automatic backwash fiber bundle filter which is used for filtering the washing BFS water is designed and its properties have been studied. The high density particles in washing BFS water and suspended slag wool are the key factors for the filtering effect. By optimization design of structure, the filter has properties of big particles precipitation, automatic discharge of floating sludge and fixed pressure backwash. Through experimental tests, the results show that: the high density particles precipitation and filter layer regeneration rate are quicker; the ability of automatic discharge floating sludge is higher. Compared with the traditional fiber filters, this kind filter efficiency of this kind filters increases 15%.

Bundle Structure

Quantization of a system constrained to move on a sphere is considered by taking a square root of the "on sphere condition". We arrive at the fiber bundle structure of the Hopf map in S2 and S4. This leads to more geometrical understanding of monopole and instanton gauge structures that emerge in the course of quantization.

We consider five-dimensional theory of gravity proposed recently by Chamseddine. It is based on the Chern–Simons five-form and the SO(1,5) gauge group. The action naturally contains a Gauss–Bonnet term, an Einstein term and a cosmological constant. We shall see that by imposing to this action the five-dimensional principal fiber bundle structure and the toroidal dimensional reduction process, the resulting U(1) gauge theory contains non-minimal couplings to gravity and nonlinear modifications to the standard Einstein–Maxwell–dilaton theory.
