The potential of the INAA and PIXE methods for the detection of mineral microelement changes in pathological human blood serum has been evaluated on nine cases of different hemopathies. These included hereditary hemolytic anemias (thalassemia, sickle cell disease, spherocytosis) and Hodgkin's disease. 23 elements (Na, Al, Cl, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br, Rb, Ag, Sb, Cs, Ba, Au, Hg, Pb) have been detected in serum. Their relative concentration variations correlated with the nature of the disease and with other pathological alterations of blood are discussed. 相似文献

It is shown that the conditional charge distributions in hadronic collisions approach a zero limiting value in the central region at asymptotic energies, provided the average total multiplicities are unbounded. A limiting charge sum rule, which shows how these distributions follow the initial charges, is established and discussed. 相似文献

The excitation function (EF) data for dissipative processes in 19F + 27Al system in the incident energy interval from 113.5 to 130 MeV are used to obtain the dependence of the charge variance and
of the interaction time as a function of the incident energy. Fluctuations are observed in the EFs of both these secondary
observables. Their correlation is supported by a mechanism based on stochastic exchange of nucleons. 相似文献

Mechanism of copper underpotential deposition at stepped faces of platinum single crystals Pt(hkl) is studied using cyclic voltammetry, scanning probe microscopy, and quantum-chemical modelling. It is shown that the first stage of UPD is one-dimensional decoration of the (100)- or (110)-orientated steps, then copper monolayer forms at (111)-terraces. The final stage is the secondary step decoration. Quantum-chemical modelling, with the using of long-distance potentials of the Cu-Pt and Cu-Cu pair interactions, allows estimating the energy of copper adsorption at different structure elements of the substrate (steps, kinks, terraces) and revealing the succession of the adatom monolayer formation; it also provides additional information for the identifying of the nature of voltametric peaks for different stages of the copper adsorption-desorption. 相似文献
