We perform a high-accuracy moment analysis of the avalanche size, duration and area distribution of the Abelian Manna model on eight two-dimensional and four one-dimensional lattices. The results provide strong support to establish universality of exponents and moment ratios across different lattices and a good survey for the strength of corrections to scaling which are notorious in the Manna u...

Fixed-energy sandpiles with stochastic update rules are known to exhibit a nonequilibrium phase transition from an active phase into infinitely many absorbing states. Examples include the conserved Manna model, the conserved lattice gas, and the conserved threshold transfer process. It is believed that the transitions in these models belong to an autonomous universality class of nonequilibrium ...

The aqueous and ethanolic extract of Myrsine africana fruits was evaluated for their anthelmintic activity against tape, hook, nodular and earthworms. The ethanolic extract was found to possess considerable lethal action against tape worms but it was not significant against the other helminths, Similarly ethereal, alcoholic and aqueous extracts of the fruits were tested for their purgative acti...
