background: chewing sugar-free gums is a convenient way to increase salivary flow. salivary flow increases in response to both gustatory (taste) and mechanical (chewing) stimuli, and chewing gum can provide both of these stimuli. the aim of this study was to compare the effect of five different flavors of sugar-free chewing gum on the salivary flow rate (sfr) and ph. materials and methods: fift...

In this paper we derive Ward-Takahashi identities from the path integral of supersymmetric five-dimensional field theories with an $SU(1,3)$ spacetime symmetry in presence instantons. We explicitly show how is enhanced to $SU(1,3)\times U(1)$ where additional $U(1)$ acts non-perturbatively. Solutions such were previously obtained correlators six-dimensional Lorentzian conformal but instanton nu...
