On the basis of adiabatic self-consistent collective coordinate method, we develop an efficient microscopic method deriving five-dimensional quadrupole Hamiltonian and illustrate its usefulness by applying it to oblate-prolate shape coexistence/mixing phenomena in proton-rich $^{68,70,72}\mathrm{Se}$. In this vibrational rotational masses (inertial functions) are determined local normal modes built on constrained Hartree-Fock-Bogoliubov states. Numerical calculations carried out using...
Effects of the isospin-symmetry breaking (ISB) beyond mean-field Coulomb terms are systematically studied in nuclear masses near $N=Z$ line. The exchange contributions calculated exactly. We use extended Skyrme energy density functionals (EDFs) with proton-neutron-mixed densities, to which we add new isospin symmetry. Two parameters associated determined by fitting mirror and triplet displacement energies (MDEs TDEs) multiplets. EDFs reproduce MDEs for $T=\frac12$ doublets $T=1$ triplets,...
Precipitation-hardened Cu–Cr–Zr alloy is proposed as a heat sink material for various components of the ITER owing to its high strength, conductivity, and superior resistance against neutron irradiation. Oxide-dispersion-strengthened copper (ODS-Cu) was selected candidate material. Hydrogen embrittlement Cu–Cr–Zr, Cu–Cr, ODS-Cu (GlidCop® CuAl60) alloys evaluated using slow strain rate technique (SSRT) in 0.1 M sodium sulfate (Na2SO4) solutions under cathodic hydrogen charging or after D2 gas...
Hyperthermia is a minimally invasive approach to cancer treatment, but it difficult heat only the tumor without damaging surrounding tissue. To solve this problem, we studied effectiveness of chemohyperthermia with docetaxel-embedded magnetoliposomes (DMLs) and an applied alternating current (AC) magnetic field. Human MKN45 gastric cells were implanted in hind limb Balb-c/nu/nu mice. Various concentrations DMLs injected into tumors exposed AC field (n = 6, each). For comparison hyperthermia...
Thermal desorption spectroscopy (TDS) of tungsten implanted with D2+ ions was performed after irradiation 8 MeV-electrons, 5.0 keV-D2+, and 6.0 MeV-Fe3+. The release peak temperatures the TDS spectra are discussed. Positron annihilation lifetime (PAL) measurements electron-irradiated were also performed, showing that single vacancies migrate a sufficient distance to arrive at sink or meet interstitial-type defects during annealing 673 K. A decrease in PAL detected for contain deuterium...
We present results of calculations based on the Skyrme energy density functional including arbitrary mixing between protons and neutrons. In this framework, single-particle states are superpositions proton neutron components is fully invariant with respect to three-dimensional rotations in isospin space. The system controlled by means isocranking method, which carries over standard cranking approach show numerical performed for isobaric analogue A=14 $A=40-56$ nuclei. also such obtained...
Background: Density functional theory (DFT) is the microscopic tool of choice to describe properties nuclei over entire nuclear landscape, with a focus on medium-mass and heavy complex systems. Modern energy density functionals (EDFs) often offer level accuracy typical phenomenological approaches based parameters locally fitted data. It clear, however, that in order achieve high quality predictions guide spectroscopic studies, current must be improved, especially isospin channel. In this...
Abstract Background and Aim: We have studied reported the usefulness of tumor local chemohyperthermia at a low‐grade temperature below 43°C with docetaxel‐embedded magnetoliposome (DML) an applied alternating current magnetic field. However, mechanisms this treatment dynamics injected docetaxel were not investigated in our previous study. Thus, we interaction chemotherapy hyperthermia treated tumor. Methods: Human MKN45 gastric cancer cells implanted hind limbs Balb‐c/nu/nu mice. DML,...
Kiritani et al. have observed a large number of small vacancy clusters without dislocations at the tip torn portions fcc metals such as Au, Ag, Cu and Ni. Small clusters, rather than dislocation cell structures, also been after high-speed compressive deformation, suggesting possibility plastic deformation dislocations. In this paper, in order to investigate mechanism dislocations, change formation energy point defects under high internal stress was estimated by computer simulation. Elastic...
