Comparative efficiency of physiotherapeutic and medicinal treatment of microelements during reparative skin regeneration
Authors: Шарипова М.М. 
Published: August 2021

Проведено сравнительное изучение влияния двух богатых микроэлементами растительных препаратов и облучения лампами полого катода (ЛПК), содержащими спектры магния и меди - ЛПК Mn&Cu в экспериментальной модели репаративной регенерации кожи. Наносимая на поверхность раны смесь препаратов Метосепт и Витанорм и их пероральное введение в дозах 40-60 мг/крысу на 30% ускоряет репаративную регенерацию кожи за счёт увеличения количества дендритных клеток и макрофагов в очаге воспаления. Ежедневное 2-минутное облучение ЛПК Mn&Cu приводило к положительному изменению динамики морфологических характеристик процесса регенерации кожных ран, ускорению дифференцировки эпителиальных клеток и также к 30%-му ускорению заживления ран. Сравнительное изучение эффективности излучения пяти фототерапевтических аппаратов показало, что уменьшение площади раневой поверхности быстрее всего происходило под влиянием магнитолазерного воздействия аппаратом «Орион+», 2-е место по этому показателю разделили аппараты «Минитаг» и ЛПК Zn&Mn, 3-е - ЛПК Zn и «Биоптрон».
A comparative study was conducted of the effect of herbal preparations and irradiation with hollow cathode lamps (HCL) producing magnesium and copper spectra, i.e., the Mg & Cu HCL, in an experimental model of reparative skin regeneration. A mixture of two micronutrient-rich drugs, Metosept and Vitanorm, were applied to the surface of the wound. Their oral administration in doses of 40-60 mg/rat accelerated the reparative skin regeneration by 30% by increasing the number of dendritic cells and macrophages in the focus of inflammation. Daily 2-min irradiation of the Mg & Cu HCL had a positive effect on the dynamics of the morphological characteristics of the skin wound regeneration process. There occurred an acceleration of epithelial cell differentiation, and also a 30% acceleration of wound healing. A comparative study of the radiation efficiency of five phototherapy devices showed that the wound surface reduction most quickly occurred during treatment with the magnetic laser “Orion+” apparatus. The 2nd most effective treatment was Minitag and HCL Zn & Mg, and the 3rd most effecivet was HCL Zn and Bioptron.

On the method of calculating the modulus of continuity of the inverse operator and its modifications with application to non-linear problems of geoelectrics
Authors: Шимелевич М.И. 
Published: August 2021

Рассматриваются априорные оценки неоднозначности (погрешности) приближенных решений условно-корректных нелинейных обратных задач, основанные на модуле непрерывности обратного оператора и его модификациях. Установлена связь модуля непрерывности обратного оператора с разрешающей способностью геофизического метода. Показано, что в классе кусочно-постоянных решений, определенных на заданной сетке параметризации, модуль непрерывности обратного оператора и его модификации монотонно возрастают с увеличением размерности сетки. Предложен метод построения оптимальной сетки параметризации, которая имеет максимальную размерность при условии, что модуль непрерывности обратного оператора не превышает заданной величины. Представлен численный алгоритм расчета модуля непрерывности обратного оператора и его модификаций с использованием алгоритмов Монте-Карло, исследуются вопросы сходимости алгоритма. Предлагаемый метод применим также для расчета классических апостериорных оценок погрешности. Приводятся численные примеры для нелинейных обратных задач геоэлектрики.
The article considers a priori estimates of the ambiguity (error) of approximate solutions of conditionally correct nonlinear inverse problems based on the modulus of continuity of the inverse operator and its modifications. It is shown that in the class of piecewise constant solutions defined on a given parametrization grid, the modulus of continuity of the inverse operator and its modifications monotonously increase with increasing mesh dimension. A method is proposed for constructing an optimal parameterization grid that has a maximum dimension provided that the modulus of continuity of the inverse operator does not exceed a given value. A numerical algorithm for calculating the modulus of continuity of the inverse operator and its modifications using Monte Carlo algorithms is presented; questions of convergence of the algorithm are investigated. The proposed method is also applicable for calculating classical posterior error estimates. Numerical examples are given for nonlinear inverse problems of geoelectrics.

Published: August 2021

Для изучения одного из важнейших процессов нефтепереработки — каталитического риформинга, требуется детализированная кинетическая модель. При разработке кинетической модели возникает сложность в связи с большим количеством компонентов реакционной смеси и большим количеством стадий химических превращений. Альтернативой могут быть сокращенные механизмы реакций, которые применимы для решения задачи и обеспечивают реалистичное описание процесса. В данной работе для анализа кинетической модели и получения сокращенного механизма реакции используются методы анализа чувствительности математической модели. Применение указанной методики позволяет выявить стадии каталитического риформинга бензина, наименее влияющие на общую динамику изменения концентраций значимых веществ реакции. Исследовано влияние исключения данных стадий на кинетику процесса с химической точки зрения. Предложена редуцированная схема каталитического риформинга бензина с исключением данных стадий. Редуцированная схема обеспечивает вполне удовлетворительное согласие как по профилям температуры, так и по профилям концентраций значимых веществ реакции.
A detailed kinetic model is required to study one of the most important oil refining processes known as catalytic reforming. The difficulty arises in connection with a large number of components of the reaction mixture and a large number of stages of chemical transformations in developing the kinetic model. An alternative may be reduced reaction mechanisms that are applicable to solve the problem and provide a realistic description of the process. In this paper, to analyze the kinetic model and to obtain an abbreviated reaction mechanism, the sensitivity analysis methods of the mathematical model are used. The least influential stages of catalytic reforming of gasoline, which do not affect the general dynamics of changes in the concentrations of significant reaction substances are identified using this technique. The effect of eliminating these stages on the kinetics of the process from the chemical point of view is analyzed. A reduced scheme for catalytic reforming of gasoline by excluding these stages is proposed. A reduced scheme provides a quite satisfactory agreement both in temperature profiles and in concentration profiles of significant substances.

В работе демонстрируется, как метод апостериорной оценки порядка точности разностной схемы по Ричардсону позволяет сделать вывод о некорректности постановки (в смысле отсутствия решения) решаемой численно начально-краевой задачи для уравнения в частных производных. Это актуально в ситуации, когда аналитическое доказательство некорректности постановки ещё не получено или принципиально невозможно.
The paper demonstrates how the method of a posteriori estimation of the order of accuracy for the difference scheme according to the Richardson extrapolation method allows one to conclude that the formulation of the numerically solved initial-boundary value problem for a partial differential equation is ill-posed (in the sense of the absence of a solution). This is important in a situation when the ill-posedness of the formulation is not analytically proved yet or cannot be proved in principle.

To answer this question, the author uses an inductive and deductive analysis framework regarding the law effectiveness theory of Lawrence M. Friedman. This paper finds that mediation in sharia economic dispute resolution at the Bukittinggi Religious Court from 2016 to 2019 has not been effective. The ineffectiveness is caused by several factors that influence it: First, in terms of legal substance, PERMA No.1 of 2016 concerning Mediation Procedures in Courts still lacks in addressing the problems of the growing community. Second, in terms of legal structure, there are no judges who have mediator certificates. Third, the legal facilities and infrastructure at the Bukittinggi Religious Court have supported mediation. Fourth, in terms of legal culture, there are still many people who are not aware of the law and do not understand mediation well, so they consider mediation to be unimportant.</span> </p><p><em>Tulisan ini mengkaji tentang bagaimana efektivitas mediasi dalam penyelesaian sengketa ekonomi syariah berdasarkan PERMA Nomor 1 Tahun 2016 di Pengadilan Agama Bukittinggi dan apa saja yang menjadi faktor penghambat keberhasilan mediasi.

Authors: Putra Dian Eka 
Published: August 2021

This study aims to anticipate a high value of grounding resistance by utilizing drainage or waste water from household waste as a planting medium to reduce the value of grounding resistance. The research method used is an experimental method of testing and measuring at field locations. In this study, a round rod electrode is coated with copper, namely testing with one electrode rod and two electrode rods that are installed in parallel or better known as the use of a driven rod. The results showed a decrease in the value of the grounding resistance where the average value for 1 grounding rod was 18.32 ohms and 11.82 ohms for the measurement of 2 grounding rods installed in parallel. From the test results, there was a decrease in the resistance value of 59.52% for 1 electrode rod and a 51.75% decrease for 2 electrode rods, where the decrease in the resistance value in the field was caused by factors of water, humidity and used water minerals from household waste. In conclusion, housing with reddish yellow podzolic soil that is clay (high soil resistance) by utilizing water drainage is a solution to reduce grounding resistance.
