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 most promising probe to establish the Majorana or Dirac nature of neutrino is neutrinoless double beta decay and effective mass would be evaluated by knowledge corresponding nuclear matrix elements. Also measurements Double Charge Exchange (DCE) interactions heavy ion beams can get information on them. NUMEN experiment based pre-existing large acceptance MAGNEX spectrometer integrated with ...

adsorption of co2 on the surface of single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (swcnts) were studied through using density functional theory (dft) calculations. optimizations of geometric were performed at the b3pw91 level of 6-311++g** method standard basis set using gaussian 03 package of program [1]. structural models were optimized and adsorption energies, band gap, charge...

Nuclear Forces. Protons give the nucleus of an atom a net positive charge. So, why doesn’t the nucleus explode? Nuclear stability is possible because the particles in the nucleus are each tiny magnets, and magnets can be arranged to attract one another. When the particles inside the nucleus have specific locations, the forces from electrical charge can be in balance with the magnetic forces fro...

Nuclear structure effects lead to small corrections electron energy-level shifts and isotope in neutral atoms but have enhanced on heavy hydrogenlike ions. The authors analyze how nuclear scale with charge, mass number, other parameters various ions, an emphasis

We present experimental results on fragmentation charge-changing cross sections of 158 A GeV lead ions (charge Z = 82e) incident on Cu and CR39 targets. To detect and identify the relativistic ions, the nuclear track detector CR39 was used. When an ion crosses a nuclear track detector foil, it produces damages at the level of molecular bonds, forming the so called “latent track”. During the che...

QCD predicts that the interactions between quarks and gluons change from a confining to a screened Yukawa form above a critical temperature Tc ∼ 150 MeV. In this talk, I review some of the key observables in heavy ion reactions which are being used to search for this new partonic Yukawa phase at SPS and RHIC. These include collective observables such as dE⊥/dyd p⊥, meson interferometry, jet que...
