In this paper we propose an improvement of the EKS nuclear parton distributions for the small x region of high energy processes, where the perturbative high parton density effects cannot be disregarded. We analyze the behavior of the ratios xGA/xGN and F A 2 /F D 2 and verify that at small x they are strongly modified when compared to the EKS predictions. The implications of our results for the...

We perform an extensive theoretical analysis of 10C nucleus with the use various approaches involving different nuclear potentials and density distributions, as well a simple cluster approach. try to explain new measured challenging experimental data on + 58Ni system at 35.3 MeV. First, we investigate effect thirteen potentials. Then, examine ten types distributions for nucleus. Finally, presen...

tyrosinase is a multifunctional copper-containing enzyme. it can catalyze two distinct reactions of melanin synthesis and benzaldehyde derivatives, which are potential tyrosinase inhibitors.  to find the relationships between charge distributions of benzaldehyde and their pharmaceutical behavior, the present study aimed at investigating nuclear quadrupole coupling constants of quadrupolare nucl...

The phenomenon of shadowing of nuclear structure functions at small values of Bjorken-x is analyzed. First, multiple scattering is discussed as the underlying physical mechanism. In this context three different but related approaches are presented: Glauber-like rescatterings, Gribov inelastic shadowing and ideas based on high-density Quantum Chromodynamics. Next, different parametrizations of n...

The ELISe experiment will be part of the installations envisaged at the NESR for FAIR. It offers worldwide unique opportunities to scatter electrons off exotic nuclei. Physics opportunities For all stable nuclei, it has been shown [1] that the central densities are about the same (≈ 0.17 nucleons/fm) and that the matter density radius is roughly proportional to the atomic number to the power of...

“Malaria” is a life-threatening blood disease in tropical regions that spreads by the bite of the Anopheles mosquito. Antimalarial medications are designed to cure or prevent this infection, and prosperous achievements in this area mostly depend on the knowing the drug-receptor interactions and active sites of medicine. This improvement can be achieved through understanding the electronic struc...

The information about sizes and nuclear density distributions in unstable (radioactive) nuclei is usually extracted from the data on interaction of radioactive nuclear beams with a nuclear target. We show that in the case of nucleus-nucleus collisions the values of the parameters depend rather strongly on the considered theoretical approach and on the assumption about the parametrization of the...
