Microscopic studies of nuclear matter under diverse conditions of density and asymmetry are of great contemporary interest. Concerning terrestrial applications, they relate to future experimental facilities that will make it possible to study systems with extreme neutron-to-proton ratio. In this talk, I will review recent efforts of my group aimed at exploring nuclear interactions in the medium...

I suggest that neutron clusters of sufficient size are bound and stable against strong decay; and that they can react with ordinary nuclei by transferring neutrons to them, accepting neutrons from them, and binding with them to form composite nuclei. Implications of this enlarged scope of nuclear physics are explored, including a chain reaction with nuclear fuel H that produces energy, He, H, a...

apotransferrin (apo tf)  in 0.1 m n-(2hydroxyethyl)piperazine-n2-ethanesulfanic acid at 25 ˚c  and ph 7.4 has been titrated with acidic solution of tb3+. the binding of tb3+ at  the two specific metal-binding sites of transferrin was followed from the changes in the difference uv spectra at 245 nm. the molar absorptivity per binding site for tb3+-tf is 22,500 ± 1000 m-1cm-1. to determine the tb...

Clusters play important role for understanding and transferring microscopic to macroscopic properties.Geometric and electron properties of Small nickel clusters up to the tetramer has been investigated by Density Functional Theory (DFT). Raising the number of nickel clusters atoms were indicated decreasing the average equilibrium (Ni-Ni) distance of atoms and also the binding energy of per atom...

Hepatocyte nuclear factor 4 (HNF-4) is an orphan intracellular receptor that appears to be a key factor in the regulation of energy metabolism. In order to gain greater understanding of the binding and activation requirements of HNF-4, we performed genetic analysis of the apoCIII promoter, a promoter that has previously been shown to be highly sensitive to HNF-4-induced transcription. We identi...

Among the significant issues of the subcontinental region, one can refer to the concern over Pakistan’s inability to maintain the security of its nuclear facilities, the illegal increase in its nuclear weapon production, extremist organizations’ access to nuclear weapons, as well as the fact that this country has not joined the NPT treaty. Meanwhile, the International Atomic Energy Agency (IAEA...

background homocysteine is a sulfur-containing amino acid which formed (mainly in the liver) during the metabolism of methionine. prior studies indicated the important role of hyperhomocysteinemia in pathogenesis and progression of alcoholic liver disease, liver steatosis and cirrhosis. one of the most important mechanisms by which homocysteine promote the development of hepatic injury is oxida...

Variational calculations of the deuteron and the triton illustrate that simple wave function ansätze become more effective after evolving the nucleon-nucleon potential to lower momentum (“Vlow k”). This is consistent with many-body wave functions becoming much less correlated at lower cutoffs, as shown by two-particle wave functions and pair-distribution functions in nuclear matter. These resul...
