Russian conservatism: outlines of a responsible political course

The article deals with the development of conservatism in modern Russian society. The current socio-political situation indicates that Russian society refuses to accept liberal Western values, giving preference to values of a conservative nature. There is an obvious demand for conservative projects to consider the values of social justice, the greater social orientation of the state, the rules and orders that are significant for people and have been with them for decades. The Russian elites are still poorly aware of the possibilities of reflecting such a request and remain within the framework of their usual ideological and conceptual approaches. The article outlines the main problem areas of Russian conservatism, which include the lack of a conservative view on the economy, a certain degree of closeness of conservatism to society, and an upset balance between renewal and preservation. Modern Russia needs to develop a new traditionalist-conservative doctrine as a possible methodology for the development of the entire Russian society, a new, broader, Russian conservatism. It is necessary to develop own “language”, taking into account civilizational, cultural and socio-historical features

Multivortex Solutions of the Weierstrass Representation

The connection between the complex Sine and Sinh-Gordon equations on the complex plane associated with a Weierstrass type system and the possibility of construction of several classes of multivortex solutions is discussed in detail. We perform the Painlev\'e test and analyse the possibility of deriving the B\"acklund transformation from the singularity analysis of the complex Sine-Gordon equation. We make use of the analysis using the known relations for the Painlev\'{e} equations to construct explicit formulae in terms of the Umemura polynomials which are $\tau$-functions for rational solutions of the third Painlev\'{e} equation. New classes of multivortex solutions of a Weierstrass system are obtained through the use of this proposed procedure. Some physical applications are mentioned in the area of the vortex Higgs model when the complex Sine-Gordon equation is reduced to coupled Riccati equations.Comment: 27 pages LaTeX2e, 1 encapsulated Postscript figur

Test beam studies of the TRD prototype filled with different gas mixtures based on Xe, Kr, and Ar

Towards the end of LHC Run1, gas leaks were observed in some parts of the Transition Radiation Tracker (TRT) of ATLAS. Due to these leaks, primary Xenon based gas mixture was replaced with Argon based mixture in various parts. Test-beam studies with a dedicated Transition Radiation Detector (TRD) prototype were carried out in 2015 in order to understand transition radiation performance with mixtures based on Argon and Krypton. We present and discuss the results of these test-beam studies with different active gas compositions.Comment: 5 pages,12 figures, The 2nd International Conference on Particle Physics and Astrophysics (ICPPA-2016); Acknowledgments section correcte

Some results of test beam studies of Transition Radiation Detector prototypes at CERN

Operating conditions and challenging demands of present and future accelerator experiments result in new requirements on detector systems. There are many ongoing activities aimed to develop new technologies and to improve the properties of detectors based on existing technologies. Our work is dedicated to development of Transition Radiation Detectors (TRD) suitable for different applications. In this paper results obtained in beam tests at SPS accelerator at CERN with the TRD prototype based on straw technology are presented. TRD performance was studied as a function of thickness of the transition radiation radiator and working gas mixture pressure

A consecutive power dispatch in wind farms to mitigate secondary frequency dips

\ua9 2024 The AuthorsWith the rapid increase of wind energy integrated into power systems, wind turbine generators (WTGs) are required to provide frequency support to maintain the system frequency stability. However, the frequency regulation is achieved by employing temporary energy reserves from WTGs at the initial stage of a disturbance. Therefore, a second frequency dip (SFD) may occur, if no other energy reserve is available to compensate the power deficiency as WTGs have to recover their operating points and rotor speeds back to the initial operating points. To deal with this problem, this paper proposes a consecutive power dispatch scheme to reduce the SFD and prevent WTGs from over-deceleration. All WTGs are divided into two groups with in a wind farm: Group 1 (G1) WTGs operating at maximum power point tracking (MPPT), Group 2 (G2) WTGs operating at deloading power. If a frequency contingency occurs, the proposed scheme aims to release an amount of kinetic energy (KE) stored in the rotating masses of G1 WTGs to improve the frequency nadir (FN). Following this, energy reserves are released from G2 WTGs to compensate the power shortage during the period when G1 WTGs rotor speeds have to be recovered. The simulation results show that the scheme causes a small SFD while improving the first FN and preventing the rotor from over-decelerations in various wind conditions, contingency sizes, and wind penetration levels

On the possibility to supercool molecular hydrogen down to superfluid transition

Recent calculations by Vorobev and Malyshenko (JETP Letters, 71, 39, 2000) show that molecular hydrogen may stay liquid and superfluid in strong electric fields of the order of $4\times 10^7 V/cm$. I demonstrate that strong local electric fields of similar magnitude exist beneath a two-dimensional layer of electrons localized in the image potential above the surface of solid hydrogen. Even stronger local fields exist around charged particles (ions or electrons) if surface or bulk of a solid hydrogen crystal is statically charged. Measurements of the frequency shift of the $1 \to 2$ photoresonance transition in the spectrum of two-dimensional layer of electrons above positively or negatively charged solid hydrogen surface performed in the temperature range 7 - 13.8 K support the prediction of electric field induced surface melting. The range of surface charge density necessary to stabilize the liquid phase of molecular hydrogen at the temperature of superfluid transition is estimated.Comment: 5 pages, 2 figure

Empirical Therapy of Complicated Pyelonephritis

The aim of the research was to analyze the effectiveness of empirical therapy in patients with established complicated upper urinary tract infection (complicated pyelonephritis).Materials and methods. 51 patients who were treated in 2018 in the urological department of the Irkutsk City Clinical Hospital N 1 were subjected to a retrospective study. The average age of patients was 55.9 ± 16.9 years.Results. Successful empirical therapy was considered in the absence of correction of the treatment regimen and the normalization of clinical blood and urine tests. Of the patients included in the study, successful empirical therapy was found in 24 (47%) patients, and required correction in 27 (52.9 %) patients. Cephalosporins as monotherapy were ineffective in 24 (57.1 %) patients, carbopenems – in one (25 %), fluoroquinolones – in all (100 %). Aminoglycosides showed the best result as a combination therapy with cephalosporins – 100 % (n = 3) of success. Based on multivariate logistic regression analysis, it was established that the detection of microhematuria and uremia in clinical analyzes upon admission to the hospital increases the likelihood of empirical monotherapy with third-generation cephalosporins by 20 % and 27 %, respectively.Conclusion. It is advisable to refrain from the use of monotherapy with fluoroquinolones and third-generation cephalosporins until more information is available about the resistance of uropathogens in the population of the Irkutsk region. Patients with impaired renal function require particularly close attention of the clinician when choosing a scheme for the empirical treatment of complicated pyelonephritis
