The first explanation on the properties of the nuclear force came from Yukawa. It said that interaction between two nucleons is mediated by mesons (heavy bosons). The most effective practical model for a quantitative nucleon-nucleon potential has been meson-exchange theory ever since. Manning-Rosen potential (M-R pot) is a diatomic molecular potential but in the moderate range it behaves as the Yukawa potential. Thus M-R pot can be considerable for the nuclear domain also. We have treated both the on- and off-shell two-particle nuclear scattering in the non-relativistic region.

Strengthening and modernization of pest management approach has fairly succeeded in India. The existing pest management approach has a predisposition in favour of chemical pesticides. Several activities are created to promote integrated pest management but the other government organizations promote chemical pesticides. The number of chemical pesticide registered every year by government is increasing very fast and the facilities for their testing are getting deteriorated with waning manpower for quality control. The progress of setting up a National Pesticide Reference Repository and a...
