Doping effect on the evolution of the pairing symmetry in n-type superconductor near antiferromagnetic phase boundary
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 integrated effect on properties and composition of high-paraffin oil sludge
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.ΠΠ½ΡΠ΅ΠΊΡΠΈΠΈ ΠΌΠΎΡΠ΅Π²ΡΠ²ΠΎΠ΄ΡΡΠΈΡ

Resistivity tensor correlations in the mixed state of electron-doped superconductor Nd2-xCexCuO4+Ξ΄
The magnetic-field dependencies of the longitudinal and Hall resistance of the electron-doped compounds Nd2-xCexCuO4+Ξ΄ in underdoped region with x = 0.14 and with varying degrees of disorder (Ξ΄) 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: Οxy(B) βΌ [Οxx(B)]Ξ². For the totality of the investigated single-crystal films of Nd2-xCexCuO4+Ξ΄/SrTiO3 the values of Ξ² 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.

The problem of the prevalence of multiple drug resistant (MDR) strains of Πcinetobacter 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.ΠΡΠΎΠ±Π»Π΅ΠΌΠ° ΡΠΎΡΠΌΠΈΡΠΎΠ²Π°Π½ΠΈΡ MDR ( multy-drug-resistant ) ΡΡΠ°ΠΌΠΌΠΎΠ² Πcinetobacter baumannii ΠΈ ΡΠ°ΡΠΏΡΠΎΡΡΡΠ°Π½Π΅Π½ΠΈΡ ΡΠ΅Π·ΠΈΡΡΠ΅Π½ΡΠ½ΠΎΡΡΠΈ Π² ΠΊΠ»ΠΈΠ½ΠΈΠΊΠ΅ ΡΡΠ΅Π·Π²ΡΡΠ°ΠΉΠ½ΠΎ Π°ΠΊΡΡΠ°Π»ΡΠ½Π° Π΄Π»Ρ ΠΎΠ½ΠΊΠΎΠ»ΠΎΠ³ΠΈΡΠ΅ΡΠΊΠΈΡ

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 β 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.ΠΡΠΎΠ±Π»Π΅ΠΌΠ° Π³ΠΎΡΠΏΠΈΡΠ°Π»ΡΠ½ΡΡ
