Will the Increasing of Anthropogenic Pressures Reduce the Biopotential Value of Sponges?

Scientifica, Volume 2015, Issue 1, 2015., 2015
Production of bioactive compounds from marine benthic organisms is suggested to relate ecologically with environment. However, anthropogenic pressures cause a considerable damage to coral reefs environment. This research aimed to define the pattern sponges biopotential values at the increasing of anthropogenic pressures to coral reef environment. Three

Relativistic description of electron scattering on the deuteron

, 1993
Within a quasipotential framework a relativistic analysis is presented of the deuteron current. Assuming that the singularities from the nucleon propagators are important, a so-called equal time approximation of the current is constructed.
