### Reformulating SU N Yang-Mills theory - arXiv

Yang-Mills theory is understood in a gauge-invariant manner, as demonstrated recently by a non-Abelian Stokes theorem for the Wilson loop operator, al-though the basic idea of this reformulation is based on the Cho-Faddeev-Niemi decomposition of the gauge potential. Key words: Yang-Mills theory, quark conﬁnement, Abelian dominance, magnetic monopole, gluon mass PACS: 12.38.Aw, 12.38.Lg

### QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE

procedure can be carried out in any laboratory ball mill. Horst and Bassarear (1976) gave a similar procedure, but lasting a bit longer, where reference ore data and data of the ore for which the value of the Bond Index is determined, are also compared. Smith and Lee (1968) have compared the data obtained through the standard Bond test and those from an open-cycle milling. Kapur (1970

### THE OPTIMAL BALL DIAMETER IN A MILL

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.
