    Asymptotic properties of Dedekind zeta functions in families of number fields

    Get PDF
    The main goal of this paper is to prove a formula that expresses the limit behaviour of Dedekind zeta functions for β„œs>1/2\Re s > 1/2 in families of number fields, assuming that the Generalized Riemann Hypothesis holds. This result can be viewed as a generalization of the Brauer--Siegel theorem. As an application we obtain a limit formula for Euler--Kronecker constants in families of number fields

    THE CONCEPT AND MEANING OF THE QUALIFICATION OF ADMINISTRATIVE OFFENCES

    Get PDF
    In this article, the author focuses attention on problematic problems of qualification of administrative crimes. The author also pays attention to the requirement of improvement of methods of qualification of administrative crimes. Article is relevant as the choice of a measure of punishment depends on qualification of administrative crime. The correct qualification does possible release from administrative responsibility, depends on it. Thus, the mistake in qualification of crime can entail the wrong decision on case of administrative crime. Such error noticed by superior court involves change or cancellation of the resolution. The novelty of a subject is explained with the aspect chosen by the author

    We prove under GRH that zeros of LL-functions of modular forms of level NN and weight kk become uniformly distributed on the critical line when $N+k\to\infty.

    On the Number of Rational Points of Jacobians over Finite Fields

    Full text link
    In this article we prove lower and upper bounds for class numbers of algebraic curves defined over finite fields. These bounds turn out to be better than most of the previously known bounds obtained using combinatorics. The methods used in the proof are essentially those from the explicit asymptotic theory of global fields. We thus provide a concrete application of effective results from the asymptotic theory of global fields and their zeta-functions

    Background. The presence of extensive bone defects significantly complicates the possibility of stable fixation and correct spatial positioning of the revision endoprosthesis components. The primary task of revision surgery is to restore the lost bone. The use of modern implants makes it possible to replace large metaphyseal defects of the tibia and femur, including AORI type 2B ΠΈ 3 bone defects. The aim of the study was to evaluate the long-term results of surgical treatment of patients with extensive bone defects (2B and 3 according to AORI) of the proximal tibia and/or distal femur using custom-made implants for revision knee arthroplasty. Methods. A retrospective clinical study was performed in 24 patients who underwent revision arthroplasty using individual implants (9 femoral and 18 tibial) made on a 3D printer in the period from 2017 to 2021. T3 defect according to AORI classification was diagnosed in 12 patients (50%), F3 defect in 1 (4.17%), F2B in 8 (33.3%), T2B in 6 (25%). All patients before surgery and 3, 6, 12 months after surgery were surveyed according to the international scales VAS, KSS, WOMAC and SF-36. Results. At the follow-up examination 12 months after the surgery, 9 out of 24 patients (37.510%) walked without additional means of support, 10 out of 24 (41.710%) with a cane, 4 out of 24 (16,78%), walkers 1 out of 24 (4.210%). There were no periprosthetic fractures during surgery and in the postoperative period. When evaluating the functional state of the knee joint, an excellent result was registered in 45.810% and 33.310%; good in 37.510% and 54.210%; satisfactory in 16.678% and 12.57% according to the KSS and WOMAC scales, respectively. When assessed on the VAS scale, there was a positive trend in the form of statistically significant decrease in pain in all patients (p0.01). Conclusion. The use of individual implants made using additive 3D printing technologies in revision knee arthroplasty in the presence of extensive bone defects (2B and 3 according to AORI) allows to perform an organ-preserving surgery without loss of the statodynamic function of the lower limb. This study has limitations due to the small sample size. We believe that it is promising to study the long-term results of surgical treatment of patients with extensive bone defects (2B and 3 AORI) of the proximal tibia and /or distal femur using individually manufactured implants for revision knee replacement and a comparative analysis of these results with those using conventional implants.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    During theΒ years ofΒ implementation ofΒ theΒ first Soviet five-year plans, great attention was paid toΒ theΒ pulp and paper industry. InΒ theΒ forest industry structure, this component was characterised by aΒ weak level ofΒ development. TheΒ bet was made onΒ theΒ creation ofΒ medium and large pulp and paper industries. InΒ theΒ Urals, where there were large reserves ofΒ forest resources and rivers, they built several plants. TheΒ largest centre ofΒ theΒ pulp and paper industry inΒ theΒ Urals and inΒ theΒ eastern regions ofΒ theΒ USSR was formed. TheΒ purpose ofΒ this article is toΒ study theΒ location, design, and launch ofΒ production ofΒ theΒ Solikamsk Sulphite Pulp Mill. InΒ theΒ mid-1930s, it was decided toΒ build anΒ enterprise. TheΒ project involved innovative technological solutions for theΒ pulp and paper industry. TheΒ launch ofΒ theΒ plant was postponed several times, theΒ project was altered, and theΒ construction was entrusted from theΒ People’s Commissariat ofΒ Forest Industry ofΒ theΒ USSR toΒ theΒ People’s Commissariat ofΒ Internal Affairs ofΒ theΒ USSR. InΒ 1940, theΒ Solikamsk Sulphite Pulp Mill became anΒ independent enterprise, but its construction continued. In March 1941, three months before theΒ outbreak ofΒ theΒ Great Patriotic War, theΒ company began theΒ production ofΒ pulp. TheΒ production was only possible within aΒ simplified scheme due toΒ theΒ absence or malfunction ofΒ equipment. TheΒ performance ofΒ theΒ enterprise was set inΒ insignificant volumes. With theΒ outbreak ofΒ war, party-state bodies and economic departments continued theΒ construction ofΒ theΒ Solikamsk Sulphite Pulp Mill and providing additional equipment. TheΒ company’s development was boosted by theΒ evacuation ofΒ several industries, theΒ start ofΒ theΒ sulphite waste liquor alcohol plant and theΒ construction ofΒ aΒ defense plant nearby. This allowed theΒ plant toΒ develop cooperative ties and master new types ofΒ products

    Acetabular defects are a major obstacle to achieving good outcomes after revision hip arthroplasty. One way to deal with this problem is to use acetabular augments. We aimed to describe mid-term outcomes of revision hip arthroplasty using acetabular augments.Materials and methods. We analyzed 85 cases (83 patients) of revision hip arthroplasty using acetabular augments performed during 2012-2018 period: 53 women and 30 men with average age of 57Β±13 years (25-79). Distribution of acetabular defects was: 51 cases β€” Paprosky IIIA, 17 cases β€” Paprosky IIIB, 12 cases β€” Paprosky IIB, 5 cases β€” Paprosky IIC. 14 patients had chronic pelvic discontinuity. Aseptic loosening was indication for the operation in 83 cases, periprosthetic hip fracture β€” 1, dislocation β€” 1. The amount of previously undregone ipsilateral hipsurgeries was 1 in 35 cases, 2 in 25 cases, 3 and more in 25 cases. Average follow-up period was 38Β±19 months (1-79).Results. The average HHS score improved from 37Β±7 preoperatively to 73Β±9 after 3 months and to 80Β±11 after 12 months postoperatively (p = 0.001). Average VAS score improved from 7Β±2 preoperatively to 4Β±1 after 3 months and to 3Β±1 after 12 months postoperatively (p = 0.001). Stable acetabular fixation was achieved in each case according to X-ray findings at final follow-up. However, radiolucent lines were present around the cup in 10 cases (11.8 %) followed by no clinical evidence of aseptic loosening. Hip center of rotation was restored from 26.40Β±18.38 mm (4-75) preoperatively to 4.78Β±5.02 mm (0-20) postoperatively relatively to 0 point. Complications manifested in 9 out of 85 cases (10,6%). Distribution of complications was: periprosthetic joint infection in 6 cases, recurrent dislocation β€” 2, periprosthetic hip fracture β€” 1.7 patients required implant removal and exchange.Conclusions. Good mid-term outcomes can be achieved using acetabular augments during hip revision surgery in setting of acetabular defects. Acetabular augments are a reliable option in case of Paprosky IIIB, IIIA defects and chronic pelvic discontinuity, providing good mechanical stability.ЦСль исслСдования β€” ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ, влияСт Π»ΠΈ ΠΎΠΆΠΈΡ€Π΅Π½ΠΈΠ΅ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ², ΠΊΠΎΡ‚ΠΎΡ€Ρ‹ΠΌ выполняСтся Ρ‚ΠΎΡ‚Π°Π»ΡŒΠ½ΠΎΠ΅ эндопротСзированиС Ρ‚Π°Π·ΠΎΠ±Π΅Π΄Ρ€Π΅Π½Π½ΠΎΠ³ΠΎ сустава, Π½Π° Π΄Π»ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ ΠΎΠΏΠ΅Ρ€Π°Ρ†ΠΈΠΈ ΠΈ стационарного лСчСния, объСм ΠΊΡ€ΠΎΠ²ΠΎΠΏΠΎΡ‚Π΅Ρ€ΠΈ, частоту ослоТнСний ΠΈ Π»Π΅Ρ‚Π°Π»ΡŒΠ½Ρ‹Ρ… исходов.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π» ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    Null values have become an urgent problem since the creation of the relational dataΒ model. The impact of the uncertainty affects all types of dependencies used in the design and operationΒ of the database. This fully applies to the inclusion dependencies, which are the theoretical basis forΒ referential integrity on the data. Attempts to solve this problem contain inaccuracy in the statementΒ of the problem and its solution. The errors in formulation of the problem can be associated with theΒ use in the definition of untyped inclusion dependencies, which leads to permutations of the attributes,Β although, the attributes in database technology are identified by name and not by their place. In addition, linking with the use of the inclusion dependencies of heterogeneous attributes, even of the same type, is a sign of lost functional dependencies and leads to interaction of inclusion dependencies and non-trivial functional dependencies. Inaccuracies in the solution of the problem are contained in the statements of axioms and the proof of their properties, including completeness. In this paper we propose an original solution of this problem only for typed inclusion dependencies in the presence of Null values: a new axiom system is proposed, its completeness and soundness are proved. On the basis of inference rules we developed an algorithm for the construction of a not surplus set of typed inclusion dependencies. The correctness of the algorithm is proved.НСопрСдСлСнныС значСния стали Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΠΉ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΠΎΠΉ с ΠΌΠΎΠΌΠ΅Π½Ρ‚Π° создания рСляционной ΠΌΠΎΠ΄Π΅Π»ΠΈ Π΄Π°Π½Π½Ρ‹Ρ….
