Fluxbranes from p-branes

It is shown how magnetic fluxbrane, Fp-brane, solutions are related to electric black p-branes by analytic continuation. Viewing the transverse space of branes as a warped cone, one finds that the cone base of the p-brane becomes the world-volume of the F(D-p-3)-brane and the world volume of the p-brane becomes the cone base of the F(D-p-3)-brane. An explicit example of the correspondence is gi...

Dyonic P-branes from Self-dual (p+1)-branes

The 'electromagnetic' Sl(2; Z) duality group in spacetime dimension D = 4k can be given a Kaluza-Klein interpretation in D = 4k + 2 as the modular group of a compactifying torus. We show how dyonic 2(k − 1)-branes in D = 4k can be interpreted as self-dual (2k − 1)-branes in D = 4k + 2 wound around the homology cycles of the torus. In particular, dyons of the D=4 N=4 heterotic string theory are ...

Enzymic formation of p-hydroxybenzoate from p-hydroxycinnamate.

An enzyme that converts p-hydroxycinnamate into p-hydroxybenzoate was found in rat liver. It is localized in the mitochondria and requires ATP. The activity is lost when the mitochondria are stored frozen overnight. Addition of magnesium chloride, cytochrome c, GSH, coenzyme A or potassium cyanide did not have any effect on the activity. When the rats were fed with alpha-p-chlorophenoxyisobutyr...
