    Doping effect on the evolution of the pairing symmetry in n-type superconductor near antiferromagnetic phase boundary

    Get PDF
    We present the investigation results of the in-plane \{rho}(T) resistivity tensor at the temperature range 0.4-40 K in magnetic fields up to 90kOe (H||c, J||ab) for electron-doped Nd{2-x}Ce{x}CuO{4+{\delta}} with different degree of disorder near antiferromagnetic - superconducting phase boundary. We have experimentally found that for optimally doped compound both the upper critical field slope and the critical temperature decrease with increasing of the disorder parameter (d-wave pairing) while in the case of the underdoped system the critical temperature remains constant and (dHc2/dT)|Tc increases with increasing of the disorder (s-wave pairing). These features suggest a possible implementation of the complex mixture state as the (s+id)-pairing.Comment: 9 pages, 2 figure

    The study is devoted to the integrated effect of acoustic treatment and addition of an inhibitor on viscosity-temperature properties and n-alkane composition in high-paraffin oil sludge. Ultrasonic treatment for 1 minute and addition of the inhibitor at the concentration of 0.05% wt. decrease viscosity by 10 times and pour point by 8Β°Π‘

    Urinary tract infections become a source of multiresistant microorganisms in the hospital due to underestimation of its incidence and importance, especially in the presence of urinary catheters. Β Particular problems are fluoroquinolone-resistant gram-negative urinary tract pathogens, as well as Enterobacteriaceae producing extended spectrum beta-lactamases. Understanding of modern trends in development of microbial resistance and the rational use of antibiotics will help oncologists to provide qualified care to patients who develop urinary tract infections.Π˜Π½Ρ„Π΅ΠΊΡ†ΠΈΠΈ мочСвыводящих ΠΏΡƒΡ‚Π΅ΠΉ (ИМП) Π²Π²ΠΈΠ΄Ρƒ Π½Π΅Π΄ΠΎΠΎΡ†Π΅Π½ΠΊΠΈ Β ΠΈΡ… распространСнности ΠΈ значимости, особСнно ΠΏΡ€ΠΈ Π½Π°Π»ΠΈΡ‡ΠΈΠΈ ΠΌΠΎΡ‡Π΅Π²Ρ‹Ρ… ΠΊΠ°Ρ‚Π΅Ρ‚Π΅Ρ€ΠΎΠ²,  становятся  источником ΠΌΡƒΠ»ΡŒΡ‚ΠΈΡ€Π΅Π·ΠΈΡΡ‚Π΅Π½Ρ‚Π½Ρ‹Ρ… ΠΌΠΈΠΊΡ€ΠΎΠΎΡ€Π³Π°Π½ΠΈΠ·ΠΌΠΎΠ² Β Π² стационарС.

    Resistivity tensor correlations in the mixed state of electron-doped superconductor Nd2-xCexCuO4+Ξ΄

    Full text link
    The magnetic-field dependencies of the longitudinal and Hall resistance of the electron-doped compounds Nd2-xCexCuO4+δ in underdoped region with x = 0.14 and with varying degrees of disorder (δ) were investigated. It was established experimentally that the correlation between the longitudinal electrical resistivity and the Hall resistivity can be analyzed on the basis of scaling relationships: ρxy(B) ∼ [ρxx(B)]β. For the totality of the investigated single-crystal films of Nd2-xCexCuO4+δ/SrTiO3 the values of β from 0.8 to 1.55 is found. The observed feature in the electron-doped two-dimensional systems can be associated both with a displaying of anisotropic s - wave or d - wave pairing symmetry and with a pinning due to an essential degree of disorder in the samples under study. © 2016 Published by Elsevier B.V

    The problem of the prevalence of multiple drug resistant (MDR) strains of Аcinetobacter baumannii in hospi- tals is a major challenge for cancer centers. To organize the measures for interrupting nosocomial transmis- sion and spread of nosocomial pathogens, it is important to determine the identity of the circulating strains of microorganisms. Assessment of the true phylogenetic relationships of the studied strains is possible by means of a cluster analysis of the isolates, followed by the construction and analysis of MSP Dendrogram in MALDI-TOF BIOTYPER system.ΠŸΡ€ΠΎΠ±Π»Π΅ΠΌΠ° формирования MDR ( multy-drug-resistant ) ΡˆΡ‚Π°ΠΌΠΌΠΎΠ² Аcinetobacter baumannii ΠΈ распространСния рСзистСнтности Π² ΠΊΠ»ΠΈΠ½ΠΈΠΊΠ΅ Ρ‡Ρ€Π΅Π·Π²Ρ‹Ρ‡Π°ΠΉΠ½ΠΎ Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½Π° для онкологичСских стационаров.

    The problem of nosocomial infections caused by Pseudomonas aeruginosa is still being actively discussed in the medical published literature. Special attention is paid to the infectious complications caused by highly resistant (XDR – extremelyor extensively-drug-resistant) strains of P. aeruginosa which are associated with increased length of hospital stay and increased cost of treatment and mortality rates. Immunocompromised cancer patiens are at significant high risk for infections caused by XDR strains. The development of antibiotic regimens for the treatment of nosocomial infections caused by strains of XDR-P. aeruginosa is of great importance.ΠŸΡ€ΠΎΠ±Π»Π΅ΠΌΠ° Π³ΠΎΡΠΏΠΈΡ‚Π°Π»ΡŒΠ½Ρ‹Ρ… ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΉ, Π²Ρ‹Π·Π²Π°Π½Π½Ρ‹Ρ… синСгнойной ΠΏΠ°Π»ΠΎΡ‡ΠΊΠΎΠΉ, ΠΏΠΎ-ΠΏΡ€Π΅ΠΆΠ½Π΅ΠΌΡƒ Π°ΠΊΡ‚ΠΈΠ²Π½ΠΎ обсуТдаСтся Π² мСдицинской Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Π΅.
