Influence of Inorganic Nano-powders on the Structure and Conductive Properties of the Network Polymer Electrolytes for Lithium Batteries
The paper describes investigation on the network polymer electrolytes based on polyethylene glycol diacrylates
and polyester diacrylates PEDA with introduction the nanopowders TiO2, Li2TiO3 and SiO2, with
different size and shape. Much attention is paid to effects of nanoparticles additives on the ionic conductivity
of network polymer electrolytes. The work is aimed to explanation of the mechanism of additives action
on Li+ - ion transport and structural changes of the polymer chains and the solvent molecules. For these
purposes the NMR method with rotation under a magic corner on nuclei 1H and NMR method with a pulsed
magnetic field gradient at the nuclei 7Li were used.

Nowadays Information Technologies (IT) are taking more and more stable position in the process of work organization in various companies, and particularly among medical organizations. Present-day scientific society has already begun to research the topic of IT integration particularities into the Health organizations. Current article is focused on this issue. Our team has planned and provided a systematic review to understand which barriers can appear in different medical centers during implementation of the innovative IT into working process. The review has been fulfilled according to the designed protocol based on the actual recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses: The PRISMA Statement. In the course of the workflow we have explored 2050 articles complied with the requirements. As a result, 23 key publications have been chosen and analyzed in detail. After considering the list of issues and barriers associated with the IT Implementation into hospitals and medical centers have been highlighted and described. We have classified them to notional clusters depending on the reasons of their appearance as well. In addition our team has defined the list of practical recommendations following which the result of the IT integration will be improved, but the risk of a negative outcome in the future can be eliminated.ΠΠ° ΡΠΎΠ²ΡΠ΅ΠΌΠ΅Π½Π½ΠΎΠΌ ΡΡΠ°ΠΏΠ΅ ΡΠ΅Ρ

Exotic state photoproduction
It is shown that the list of unusual mesons planned for a careful study in
photoproduction can be extended by the exotic states with which should be looked for in the decay
channels in the reactions and . The full classification of the states by their
quantum numbers is presented. A simple model for the spin structure of the , , and reaction amplitudes is formulated and the tentative estimates of the
corresponding cross sections at the incident photon energy
GeV are obtained: b, b, b, and b. The problem of the
signal extraction from the natural background due to the other production channels is discussed. In particular the estimates are
presented for the , , and reaction cross sections.
Our main conclusion is that the search for the exotic
states is quite feasible at JEFLAB facility. The expected yield of the events in a 30-day run at the 100% detection
efficiency approximates events.Comment: 19 pages, revtex, 1 figure in postscipt, some comments and references

Feature in accumulation of microdefects in copper under shock-wave loading
The optical microscopy and X-ray diffraction methods were
used to investigate distribution of micro-, and macro-defects in copper
samples recovered after shock-wave loading. The electric gun GNUV was used
to generate the shock wave. Sample loading dynamics was recovered by the
free surface velocity measured based on the Doppler shift in the wavelength
of the probe laser radiation. In-depth distribution of defects was compared
for two modes of sample loading. In the first mode, samples were loaded by
the shock wave whose amplitude was insufficient for spalling, which was
initiated by the shock wave in the second mode
EPR Spectroscopy of <sup>53</sup>Cr <sup>3 +</sup> Monoisotopic Impurity Ions in a Single Crystal of Scandium Orthosilicate Sc <inf>2</inf>SiO <inf>5</inf>
Monoisotopic 53Cr 3 + impurity ions in scandium orthosilicate single crystal (Sc 2SiO 5) are studied by the method of electron paramagnetic resonance in the X-band frequencies. The directions of the main principal magnetic axes and the parameters of the effective spin Hamiltonian that describe the magnetic characteristics of the impurity centers of chromium, which replaces scandium in two structurally nonequivalent positions, are determined. It is shown that the orientation dependencies of the EPR spectra are well described by the second-order spin Hamiltonian corresponding to the orthorhombic symmetry of the local crystal field acting on the impurity ion. It was assumed that the g-tensor and the A-tensor determining the Zeeman energy of electronic levels in a magnetic field and the hyperfine interaction of electron and nuclear spins are isotropic, and the entire anisotropy of the EPR spectra is due to the anisotropy of the D-tensor, which describes the fine structure of electronic levels in a crystalline electric field. A strong dependence of the probability of βforbiddenβ transitions between hyperfine sublevels of electronic levels on the orientation of an external magnetic field is established. Moreover, for some orientations, the probability of βforbiddenβ transitions exceeds the probability of βallowedβ transitions
EPR spectroscopy of <sup>53</sup>Cr monoisotopic impurity ions in a single crystal of yttrium orthosilicate Y<inf>2</inf>SiO<inf>5</inf>
Β© 2020 Elsevier B.V. The electron paramagnetic resonance spectra of 53Cr monoisotopic impurity ions in yttrium orthosilicate single crystals (Y2SiO5) were studied by electron paramagnetic resonance (EPR) in the X-band. The directions of the principal magnetic axes and the parameters of the effective spin Hamiltonian, which describes magnetic characteristics of the impurity centers of chromium are determined. It is shown that the orientation dependencies of the EPR spectra are described by the second-order spin Hamiltonian corresponding to the rhombic symmetry of the local crystal field acting on the impurity ion. It was assumed that the g-tensor and A-tensor describing the Zeeman energy of electron levels in a magnetic field and the hyperfine interaction of electron and nuclear spins are isotropic, and the entire anisotropy of the EPR spectra is due to the anisotropy of the D-tensor, which describes the fine structure of electron levels in crystal electric field. A strong dependence of the probability of forbidden transitions between hyperfine sublevels of electron levels on the orientation of an external magnetic field is established. Moreover, for some orientations, the probability of forbidden transitions becomes comparable to the probability of allowed transitions
