COMPACTNESS OF THE RESOLVENT OF THE SECOND-ORDER ELLIPTIC OPERATOR AND THE KOLMOGOR ESTIMATES OF THE WIDTH OF THE SET M {UD(L):||BXUQ(X)U||pT}. Phys-Math), associate professor at Al-Farabi Kazakh State University, Almaty, Kazakhstan The work is devoted to the study of the spectral properties of the operator generated by a second-order singular elliptic system with unbounded lower coefficient in the Lebesgue space Lp Lp(R2,R2). The boundedness and compactness of the resolvent of the operator generated by the second-order singular elliptic system with unbounded lower coefficient in Lebesgue space is proved. We also obtained exact two-sided estimates of the Kolmogorov width distribution function associated with the approximate characteristics of a second-order singular elliptic system with an unbounded lower coefficient.
The estimates of the boards allow us to judge the speed of convergence of the approximate solutions of the considered differential equation to the exact one.

In [2] they proved that the system of eigenfunctions and associated functions (E and AF) of the problem (1) – (2) forms a Riesz basis [3] with the brackets in any integral perturbation of boundary conditions, and in strong regularity of the boundary conditions E and AF form a Riesz basis. In the particular case of integral perturbation of periodic boundary conditions for multiple differentiation operator instability of the basis property of E and AF is investigated in [4]. Aldashev proves the unique solvability of the classical solution of the Dirichlet problem for degenerate three-dimensional elliptic and elliptic-parabolic equations.
Previously, this author has shown the solvability of the Dirichlet problem for three-dimensional elliptic-parabolic equations with degeneracy of type and order in a cylindrical domain. Regularization method and sufficient conditions for existence and uniqueness of the solution of such integral equations are derived. In this paper, we study the regularization of nonlinear integral Volterra equations of the first kind.
A regularizing operator is obtained, the uniform convergence of the regularized solution to the exact solution of the equations in the ball is proved. The system is considered to be a nonlinear integral Volterra equation of the first kind, a system of equations with a small parameter.

ALTERNATIVE AND EXTENDED OPTION OF THE METHOD OF PROTONING THE NUMERICAL SOLUTION OF THE 1ST BOUNDARY VALUE PROBLEM FOR LINEAR DIFFERENTIAL EQUATIONS. In this article, iterative formulas are received for classical sweeping analogous to formulas (Thomas' algorithm in the English-language literature), for the numerical solution of the first boundary value problem of second-order differential equations, when the widely used method of sweeping can lead to disappointing results. Especially cases are considered that are particularly important: sweep formulas, when the coefficient of equation (has a negative or alternating sign) and the boundary conditions do not meet the conditions of calculation stability of the widely used sweep method.
As a result, a new algorithm is proposed as an alternative to the sweep method for numerically solving second-order linear differential equations with fixed boundary conditions. The obtained formulas can be used for the numerical solution of the initial boundary value problem with discontinuous coefficients. The algorithm is tested on specially selected numerical examples that reflect the characteristics of the considered boundary value problems.

Benjamin Bloom's eponymous taxonomy grew out of a series of informal discussions with colleagues that began at the American Psychological Association in 1948. In 2007, Andrew Churches took Bloom's work a step further when he introduced Bloom's Digital Taxonomy. Churches added ways to use Web 2.0 technologies for each cognitive level in Bloom's revised taxonomy.
The report includes numerous charts, work aids, and activities to help you get the most out of the innovations and updates in Bloom's Taxonomy for yourself and your work group. Bloom's Taxonomy arose from a series of informal discussions with colleagues that began at the American Psychological Association in 1948. However, teachers, instructional designers, researchers, and evaluators who use this classification generally refer to it as Bloom's Taxonomy.
Although several changes have been proposed, Bloom's description of learning domains and levels of complexity is still widely used. Both the original Bloom's Taxonomy and its later revisions can be used to develop much-needed critical thinking. Bloom's taxonomy provides a universally effective strategy for creating all types of content to drive learning.
Bloom's taxonomy guides teachers to develop higher levels of thought process for critical or creative thinking. In Bloom's Taxonomy: A Forty-Year Retrospective edited by Lorin Anderson and Lauren A. Chicago: National Society for the Study of Education).

This paper presents the numerical method for solving the heat equation and modeling the thermal processing of oil slime. Today, Kazakhstan is one of the leading countries in the production and processing of oil and oil products. In Kazakhstan, the urgency of this urgent task was first noted in the January Environmental Law of the Republic of Kazakhstan.
Some of the most dangerous contaminants and the most important wastes by weight in the oil industry are crude oil sludge and also acid residues. At the same time, the volume of secondary waste can amount to 1/10 of the processed oil sludge. On each fractional time layer, one of the spatial differential operators is implicitly approximated (scalar sweeping is performed in the corresponding coordinate direction), while the other is explicit [14].
Today, most of the major issues affecting societies are centered around environmental protection.

При термическом отжиге полупроводника происходят процессы окисления, изменение электронных состояний на границе раздела Si-SiO2, что влияет не только на технологию изготовления полупроводниковых приборов, но и при их эксплуатации. Целью данной работы является определение конкретных изменений структуры и их напряжений, образования оксидов и их связи со структурными изменениями при отжиге, а также влияние термического отжига на образующиеся системы Si-SiO2, Si-SiO. в поверхностных слоях кремния. Изучение процентного содержания кремния в исходном образце при термическом отжиге до 600°С и образования оксидов при различном времени термического отжига на воздухе привело к определенной зависимости увеличения процентного содержания оксидов, образующихся на поверхности См [ 14].
Анализ содержания Si и образующихся на его поверхности оксидов показывает, что с увеличением времени термического отжига в основном образуется диоксид кремния, который через 120 минут термического отжига достигает процентного насыщения. Увеличение времени термического отжига вызывает увеличение содержания SiO2 на поверхности кремниевой пластины за счет диффузии кислорода без существенного влияния на структуру кремния. Термический отжиг, являющийся одной из составляющих лазерного излучения, существенно продолжает воздействовать на систему Si-SiO2, а напряжения, возникающие при термическом отжиге, возрастают на границе раздела Si-SiO2, где прослойка, обогащенная оксидом кремния, и в кремнии - кислородом и различными структурными дефектами, возникающими при окислении [15].
В то же время ясно, что непрерывное лазерное излучение при воздействии на систему Si-SiO2, образовавшуюся после предварительного термического отжига, приводит к структурной перестройке, возникновению температурного градиента, способствующего упрочнению, образованию дефектов, плавление поверхностных слоев кремния с образованием дислокации и изменением механических напряжений [16]. Нельзя исключить увеличение плотности электронных состояний на поверхности после облучения такой системы из-за преобладания механизма дефектообразования на границе раздела Si-SiO2 и в приповерхностной области кремния [17]. Определенные режимы и режимы термического отжига кремния, среди которых от 400°С до 600°С изменения параметра ᾠ, свидетельствующие о наличии структурных напряжений в кристаллической решетке Si, достаточно слабые.
