Implementation of International Standards for Determining an Efficient Civil Law Remedy by a National Court
The article is devoted to studying the effectiveness of protection of violated, unrecognised or disputed rights, freedoms or interests of individuals, rights and interests of legal entities, the interests of the state in civil proceedings. The purpose of the article is to study how to implement international standards for determining an efficient civil law remedy by the court: (based on the case-law of the European Court of Human Rights and national case law). Clarification of the essence of novels of substantive and procedural law in determining the court's effective way to protect private law as the final judicial procedure of the right to judicial protection was by comparative law, methods of analysis, modelling and synthesis with the implementation of related elements of classical methods of protection and reception of the best acquisitions of legal systems of foreign countries, norms of the Convention of the case-law of the European Court of Human Rights (from now on – ECtHR). The dialectical method of cognition and the qualitative empirical method were also the main ones, by means of which the legal nature of the category "efficiency" and "determination by the court of an effective way of protection of private law and interest" were clarified.
Keywords: Litigation, the remedy of private law, international standards, ECtHR, ECHR
Influence of subclinical hypothyroidism on indicators of 24-hour arterial blood pressure monitoring in hypertensive patients with high additional risk
Significant prevalence of arterial hypertension (40 % of the adult population) and unsatisfactory level of high blood pressure adequate control (only 14 % of the urban and 8 % of the rural population in Ukraine) underlines the need to study the factors influencing AH course and contributing to a lack of antihypertensive therapy efficacy. One of such factors is subclinical hypothyroidism (SH).
Aim. To study Influence of subclinical hypothyroidism on indicators of 24-hour arterial blood pressure monitoring in hypertensive patients with high additional risk.
Materials and methods. After signing of written informed consent for the study, 124 patients with arterial hypertension (AH) and 16 practically healthy people (control group) were involved. The main group included 32 AH patients (women 87.5 % (n = 28), men 12.5 % (n = 4)) with moderately elevated thyroid stimulating hormone level (TSH) (4.0–15.6 μD/ml) and normal levels of thyroid hormones. The comparison group consisted of 92 AH patients (women 81.52 % (n = 75), men 18.48 % (n = 17)) with normal levels of TSH (0.4–4.0 μD/ml). The groups of patients were matched for age (54.16 ± 10.16) years versus (57.69 ± 9.76) years, (P = 0.093), sex (P = 0.4319), height (P = 0.993), weight (P = 0.719), body surface area (P = 0.901), body mass index (P = 0.669). All patients underwent a combined 24-hour blood pressure monitoring and ECG using a “Cardiology-04-AD-3” device (St. Petersburg, RF).
Results. AH patients with or without concomitant SH were of comparable mean daytime and nighttime indices of SBP and DPB, indicators of SBP and DBP variability, PBP, indices for hypertension and hypotension, circadian indices, indices of percentage SBP and DBP increases, SBP and DBP load (with the exception of daytime SBP load). Patients with AH and SH, in contrast to AH patients without SH, tended to have 8.5 % (P < 0.05) higher indices of daytime SBP load, and 19.3 % (P < 0.05) lower daytime DBP hypotension index.
Conclusions. AH patients with or without concomitant SH are comparable by the vast majority of ABPM indicators. However, in AH patients with concomitant SH, unlike those without SH, a larger daytime SBP load and a lower daytime DBP hypotension index were detected
Bulk-boundary correspondence in three dimensional topological insulators
We discuss the relation between bulk topological invariants and the spectrum
of surface states in three dimensional non-interacting topological insulators.
By studying particular models, and considering general boundary conditions for
the electron wavefunction on the crystal surface, we demonstrate that using
experimental techniques that probe surface states, only strong topological and
trivial insulating phases can be distinguished; the latter state being
equivalent to a weak topological insulator. In a strong topological insulator,
only the {\it parity} of the number of surface states, but not the number
itself, is robust against time-reversal invariant boundary perturbations. Our
results suggest a \z definition of the bulk-boundary correspondence,
compatible with the \z classification of topological insulators.Comment: TeXLive (Unix), revtex4-1, 7 pages, 3 figure
Microstructure and mechanical properties of V–Cr–Zr alloy with carbide and oxide strengthening
A comparative study of the effectiveness of carbide and oxide types of strengthening of V–Cr–Zr alloy was carried out by means of a comprehensive certification of structural-phase state parameters and measuring the mechanical properties characteristics. It has been shown that the use of chemical-heat treatment contributes to a significant increase in the thermal stability of the microstructure and mechanical properties of V–Cr–Zr alloy in comparison with carbide strengthening under the conditions of thermomechanical treatment. A controlled increase in the volume fraction of fine particles based on ZrO2, along with an increase in the concentration of oxygen in the solid solution, leads to a decrease in the rate of oxides coagulation and an increase in the thermal stability of high disperse heterophase structure. These effects contribute to the retention of high defect structural states with nonzero values of crystal lattice curvature even after high-temperature (0.67 Tmelt) anneals. The high efficiency of dispersion and substructural strengthening is a consequence of blocking dislocation slip by fine particles stabilized by oxygen in a solid solution
Microstructure and mechanical properties of vanadium alloys after thermomechanical treatments
The results of investigation of dispersion strengthening effect on parameters of structural-phase states and characteristics of short-term strength and ductility of vanadium alloys of V–4Ti–4Cr, V–2.4Zr–0.25C, V–1.2Zr–8.8Cr and V–1.7Zr–4.2Cr–7.6W systems with different concentration of interstitial elements after optimized thermomechanical treatment mode were summarized. It was shown that for effective realization of dispersion strengthening by Orowan-type mechanism at least 25–50% of the initial volume fraction of coarse particles should be transformed into fine-disperse state and redistributed over the volume of material
