Classical solution of the mixed problem for the Klein – Gordon – Fock type equation in the half-strip with curve derivatives at boundary conditions
Authors: Korzyuk V. I. , Stolyarchuk I. I. 
Published: January 2019

The mixed problem for the one-dimensional Klein – Gordon – Fock type equation with curve derivatives at boundary conditions is considered in the half-strip. The solution of this problem is reduced to solving the second-type Volterra integral equations. Theorems of existence and uniqueness of the solution in the class of twice continuously differentiable functions were proven for these equations when initial functions are smooth enough. It is proven that the fulfillment of the matching conditions on the given functions is necessary and sufficient for the existence of the unique smooth solution when initial functions are smooth enough. The method of characteristics is used for the problem analysis. This method is reduced to splitting the original area of definition to the subdomains. The solution of the subproblem can be constructed in each subdomain with the help of the initial and boundary conditions. Then, the obtained solutions are glued in common points, and the obtained glued conditions are the matching conditions. This approach can be used in constructing as an analytical solution when a solution of the integral equation can be found in an explicit way, so an approximate solution. Moreover, approximate solutions can be constructed in numerical or analytical form. When a numerical solution is built, the matching conditions are essential and they need to be considered while developing numerical methods.
Method of iteration of solving invariant equations with an approximate operator in the case of an arbitrary choice of the regularization parameter
Authors: Matysik O. V. , Savchuk V. F. 
Published: January 2019

In the introduction, the object of investigation is indicated – incorrect problems described by first-kind operator equations. The subject of the study is an explicit iterative method for solving first-kind equations. The aim of the paper is to prove the convergence of the proposed method of simple iterations with an alternating step alternately and to obtain error estimates in the original norm of a Hilbert space for the cases of self-conjugated and non self-conjugated problems. The a priori choice of the regularization parameter is studied for a source-like representable solution under the assumption that the operator and the right-hand side of the equation are given approximately. In the main part of the work, the achievement of the stated goal is expressed in four reduced and proved theorems. In Section 1, the first-kind equation is written down and a new explicit method of simple iteration with alternating steps is proposed to solve it. In Section 2, we consider the case of the selfconjugated problem and prove Theorem 1 on the convergence of the method and Theorem 2, in which an error estimate is obtained. To obtain an error estimate, an additional condition is required – the requirement of the source representability of the exact solution. In Section 3, the non-self-conjugated problem is solved, the convergence of the proposed method is proved, which in this case is written differently, and its error estimate is obtained in the case of an a priori choice of the regularization parameter. In sections 2 and 3, the error estimates obtained are optimized, that is, a value is found – the step number of the iteration, in which the error estimate is minimal. Since incorrect problems constantly arise in numerous applications of mathematics, the problem of studying them and constructing methods for their solution is topical. The obtained results can be used in theoretical studies of solution of first-kind operator equations, as well as applied ill-posed problems encountered in dynamics and kinetics, mathematical economics, geophysics, spectroscopy, systems for complete automatic processing and interpretation of experiments, plasma diagnostics, seismic and medicine.

Published: January 2019

Nowadays, the infection recurrence rate in osteomyelitis is still high. New hardware not only allowing one to stabilize bone fragments, but also having antibacterial activity seems to be an extremely useful and promising task. The goal of the study was to assess the effectiveness of use of an antibacterial coating based on polymethylmethacrylate cement in experiment and in infected nonunions of long tubular bones of the lower limbs. Bone cement-based coatings impregnated with antibiotics were formed on titanium plates. A plate rinse was carried out; antibiotic concentrations in the rinsed solutions were estimated by a serial broth microdilution method. The antibacterial activity of control and rinsed samples against the antibiotic-sensitive and multiple-antibiotic-resistant Staphylococcus aureus and Pseudomonas aeruginosa strains was estimated by a bilayer agar method. Clinical part. The study included 70 patients divided into 2 groups: osteosynthesis with antibacterial-coated interlocking nail (40 patients, main group) and osteosynthesis with an external fixation device (30 patients, control group) comparable in age, sex and disease duration. The effectiveness of the antibacterial coating was analyzed by the duration of systemic use of antibiotics and infection recurrence rate. The concentrations of meropenem and phosphomycin in the rinsed solutions obtained at one-fold and two-fold treatments were sufficient to suppress the growth of control strains. Vancomycin-containing samples possessed sufficient antibacterial activity against both methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) S. aureus strains, double rinse of the samples eliminated their bactericidal properties. The duration of systemic antibacterial therapy in the main group was statistically significantly lower than in the control group (U = 77.5, p < 0.001), and in the main group the infection recurrence rate was lower than 32.5 % vs. 86.7 % (χ2 = 20.39, p < 0.001). The PMMA-based coating impregnated with phosphomycin, meropenem or vancomycin possesses sufficient and long-lasting antibacterial activity, mainly against antibiotic-sensitive strains. An adequate use of such a coating in clinical practice allows one to obtain the desired result of treatment.

Problems and prospects of development of horticulture in Russia
Authors: Kulikov I. M. , Minakov I. A. 
Published: January 2019

In Russia, about 25 kg of fruit per year is produced per capita, which is 75 % of the rational norm of nutrition. In the domestic agri-food market, more than 70 % are imported fruits. At the present stage, a negative trend in the development of horticulture is the reduction of areas under fruit and berry crops. For 2000-2017 their total area decreased by 250 thousand hectares, or by 32.1 %. A signifi cant increase in the yield of orchards and berry fi elds (88.9 percent) during the reduction of surface area did not ensure a high growth rates of fruit production. During the period under review, their gross collection increased by only 7.6 per cent. The growth of fruit and berry production has been achieved for the set of horticulture development in the households. Here the production of fruits increased to 58.4 %. In agricultural organizations, it decreased by 54.0%. To solve the problem of providing the population with fruits in terms of import substitution, it is necessary to increase the area of orchards by 378 thousand ha, or 73.1%, which will bring the gross harvest of fruit and berry products to 10320 thousand tons. Important areas of development of horticulture is the concentration of fruit production in specialized organizations and farms, the transfer of the sector to an innovative way of development, increasing the investment attractiveness of horticulture through the improvement of state support and the creation of integrated structures.

Vizsgálatunk arra irányult, hogy a növényvédelemben széles körben alkalmazott tebukonazol hatóanyagú MYSTIC 250 EC gombaölő szer és egy környezetszennyező nehézfém, az ólom-acetát egyedi és együttes méreghatását tanulmányozzuk házityúk-embriókban. A toxikológiai vizsgálat során kísérleti anyagként 0,01%-os ólom-acetát oldatot, valamint a MYSTIC 250 EC (250 g/l tebukonazol) 0,1%-os, a forgalmazó által ajánlott emulzióját alkalmaztuk. A bemerítéses kezelést a keltetés megkezdése előtt, míg a tojások feldolgozását a várható kelés előtt 2 nappal, a keltetés 19. napján végeztük el. A kórbonctani vizsgálat során lemértük az embriók testtömegét, feljegyeztük az elhalások számát, továbbá rögzítettük a makroszkópos fejlődési rendellenességeket. Statisztikai értékelésnél az élő embriók testtömegeinek összehasonlításához egytényezős varianciaanalízist (One-way ANOVA), az elhalások és a fejlődési rendellenességek számának elemzéséhez Fischer-féle egzakt tesztet alkalmaztunk. A vizsgálati anyagokkal elvégzett egyedi és együttes kezelések eredményeként a kezelt csoportokban az embriók testtömeg értékei szignifikánsan kisebbek voltak a kontroll csoporthoz viszonyítva. Az egyedi és együttes kezelések következtében jelentkező embrióletalitás - a fungiciddel egyedileg kezelt csoport kivételével - szignifikánsan emelkedett a kontroll csoporthoz képest. A fejlődési rendellenességek sporadikusan fordultak elő a kezelt csoportokban, teratogén hatás nem volt igazolható. Kísérletünkben felhasznált 0,01%-os ólom-acetát oldat és MYSTIC 250 EC fungicid 0,1%-os emulziójának egyedi méreghatása toxikus volt a tojásban fejlődő házityúk-embriókra nézve. A kísérleti anyagok együttes alkalmazása során az embriótoxikus dózisú ólom-acetát mellett a növényvédelmi gyakorlatban felhasznált MYSTIC 250 EC gombaölő szeres kezelés fokozta az embriótoxicitást, a toxikus interakció additív jellegű volt.

Published: January 2019

BACKGROUND: Pulmonary nodule detection can significantly influence the early diagnosis of lung cancer while is confused by false positives. OBJECTIVE: In this study, we focus on the false positive reduction and present a method for accurate and rapid detection of pulmonary nodule from suspective regions with 3D texture and edge feature. METHODS: This work mainly consists of four modules. Firstly, small pulmonary nodule candidates are preprocessed by a reconstruction approach for enhancing 3D image feature. Secondly, a texture feature descriptor is proposed, named cross-scale local binary patterns (CS-LBP), to extract spatial texture information. Thirdly, we design a 3D edge feature descriptor named orthogonal edge orientation histogram (ORT-EOH) to obtain spatial edge information. Finally, hierarchical support vector machines (H-SVMs) is used to classify suspective regions as either nodules or non-nodules with joint CS-LBP and ORT-EOH feature vector. RESULTS: For the solitary solid nodule, ground-glass opacity, juxta-vascular nodule and juxta-pleural nodule, average sensitivity, average specificity and average accuracy of our method are 95.69%, 96.95% and 96.04%, respectively. The elapsed time in training and testing stage are 321.76 s and 5.69 s. CONCLUSIONS: Our proposed method has the best performance compared with other state-of-the-art methods and is shown the improved precision of pulmonary nodule detection with computationaly low cost.
