New data on the , symbiosisf nitrogen fixation in the plant. The morphological and histochemical studies referred to in this work showed a complex relationship between the three partners (., ., bacteria), with special emphasis on the biological recognition of these organisms in the symbiosis. The bacteria, present in all stag

r–Lagrange systems constituted by the Hamiltonian ones. The Hamiltonian systems are classically defined by using the Poisson brackets, which are strictly connected with first integrals; several properties of the Poisson brackets, as their relation with changes of coordinates, are explored in detail.

We show that due to the virtual intermediate neutrino in the neutrinoless double-beta decay the classification according to allowed, first for
