Published: March 2023

Penelitian ini bertujuan untuk memilih rute optimal pengangkutan sampah pada UKM Kelompok Usaha Bersama Peduli Sampah Kecamatan Tanah Abang sehingga dapat meminimalkan biaya transportasi. Metode Branch and Bound dan Nearest Neighbour dipilih dalam menyelesaikan masalah pada penelitian ini. Metode Branch and Bound adalah metode pencarian di dalam ruang solusi secara sistematis. Sedangkan metode Nearest Neighbour adalah sebuah teknik menyelesaikan permasalahan rute dengan menentukan titik terdekat dengan jarak terpendek. Hasil perhitungan untuk rute awal pengangkutan sampah didapatkan jarak tempuh per tahun sebesar 5.356,8Km, waktu tempuh per tahun sebesar 12.480 Menit dan biaya transportasi per tahun sebesar Rp.11.584.793,6. Dari hasil penelitian menggunakan metode Branch and Bound didapat jarak tempuh per tahun sebesar 4.454,4 Km, waktu tempuh per tahun sebesar 10.560 Menit dan biaya transportasi per tahun sebesar Rp.9.641.548,8. Dengan metode Nearest Neighbor didapat jarak tempuh per tahun sebesar 4.454,4  Km, waktu tempuh per tahun sebesar 10.368 Menit dan biaya transportasi per tahun sebesar Rp.9.641.548,8. Perbandiangan antara kedua metode tersebut menghasilkan jarak tempuh dan biaya transportasi yang sama, tetapi terdapat perbedaan pada waktu tempuh. Metode Nearest Neighbour memiliki waktu tempuh yang lebih cepat sehingga metode ini terpilih untuk mencapai tujuan penelitian.
Elastoplastic Quasi-Static and Impact Load Response of Steel Structure Sub-Assemblage with CFRP Strips
Authors: Aloosi Ali Al , Razzaq Zia
Published: March 2023

Presented in this paper is the outcome of an experimental investigation of the elastoplastic quasi-static and impact load response of a steel sub-assemblage constructed using a pair of hollow square section members with or without Carbon Fiber Reinforced Polymer (CFRP) strips. The sub-assemblage consists of a long structural member welded to a short member, thus representing a typical combination of a column and a beam on the face of a multi-story steel building frame. The column is subjected to a lateral quasi-static or impact load. Tests are conducted on four separate steel sub-assemblages. The first two tests are conducted with a gradually increasing flexural load applied at the midspan of the column up to the collapse condition without and with CFRP strips, respectively. Additional two tests are performed with a flexural impact load applied at midspan of the column also both without and with CFRP strips, respectively. The results of the study show that CFRP strips substantially increase the quasi-static collapse load of the sub-assemblage. However, when subjected to an impact load, the steel structure sub-assemblage with CFRP strips developed smaller strains in comparison with those without the CFRP strips. The post-impact time-dependent strains also became considerably smaller for the sub-assemblage with CFRP strips.
Integration of Floating Solar Photovoltaic Systems with Hydropower Plants in Greece
Authors: Vourdoubas John
Published: March 2023

Floating solar photovoltaics in water bodies is a novel clean energy technology which has been developed rapidly during the last decade. The current work investigates the possibility and the potential of installing floating photovoltaic systems in the existing hydropower plants in Greece. Studies related with the use of floating photovoltaics in water reservoirs in Greece are limited so far. The characteristics of the existing 24 hydropower plants in Greece have been used for the estimation of the solar photovoltaic systems which can be installed in their water reservoirs. It has been found that the nominal power of these solar energy systems which can be installed in their water reservoirs, covering 10% of their water surface, is at 3,861 MWp while the annual generated electricity at 5,212.35 GWh corresponding at 10.04 % of the annual electricity demand in the country. The capacity factor of the integrated solar and hydro power systems is increased by more than 20%. The research indicates that the existing hydropower plants in Greece can host, in their water dams, floating photovoltaic systems generating significant amounts of green electricity while they also result in many environmental benefits. These novel solar energy systems can contribute, together with other benign energy technologies, in the achievement of the national and EU target for net zero carbon emissions by 2050.
Künstliche Intelligenz revolutioniert Projektmarketing
Authors: Steeger Oliver
Published: March 2023

Künstliche Intelligenz – kurz: KI – gilt als Megatrend in Industrie und Wirtschaft. Jetzt zeigt sich die praktische Anwendung auch im Projektmanagement. Beispiel im Projektmarketing: Fortschritte in der KI lassen Computer wie einen Menschen schreiben und zeichnen. Heute ist es kinderleicht (und preiswert), Texte und Grafiken mit KI zu generieren. Dies kann Projektmarketing einfacher und effizienter machen. Für viele Projekte wird das sonst teure Marketing so erst finanzierbar. Doch der Einsatz von Kollege Computer hat Schattenseiten. Das System neigt zu Fehlern und (teils haarsträubenden) Ungenauigkeiten. Wie sich Künstliche Intelligenz im Projektmarketing einsetzen lässt, wo die Chancen liegen und auf welche „Stolpersteine“ Projektmanager achten sollten – dies erklärt Expertin Professor Doris Weßels im Interview.

Authors: Armbruster Judith
Published: March 2023

KI als Technologie stellt besondere Anforderungen und Herausforderungen an die Durchführung von Projekten. Dabei sind Digitalisierung und die Verfügbarkeit von Daten technische Randbedingungen, die als Grundlage für eine erfolgreiche Umsetzung dienen. Darüber hinaus stellt die explorative Natur der Projekte die Notwendigkeit zur Vorgehensweise im Rahmen eines iterativen Prozesses. Besonders spannend ist jedoch der Startpunkt, von welchem aus in ein KI-Projekt gestartet wird. Je nach Vorwissen und Kenntnisstand werden hier eher vage Ideen oder konkrete Ziele formuliert. Dabei können drei Stufen in der Herangehensweise unterschieden werden, wobei sich jeweils andere Methoden zur gemeinsamen Weiterarbeit eignen. Es ist elementar die Ideen und Ziele im Projekt zusammenzubringen und zu konkretisieren, um mit modernen Technologien und Methoden einen Mehrwert zu stiften.

Authors: Rodríguez-Guerrero Miguel , Barrera-Algarín Evaristo
Published: March 2023

El artículo examina las características y funcionalidades que, con las tecnologías de la información y la comunicación, desarrollan dos movimientos sociales en sus modos de acción-organización para superar los conflictos sociopolíticos y ecosociales presentes. Para ello se utiliza una metodología mixta, con la aplicación de 12 entrevistas semiestructuradas y 63 cuestionarios a activistas sociales. Los resultados describen, en primer lugar, una dimensión externa enfocada a la visibilización de los discursos y nuevos modos de acción de la protesta. Mientras que, en segundo lugar, se muestra una descripción pormenorizada de los principales cambios que integran sus estructuras organizacionales o dimensiones internas. Se concluye que el uso estratégico de estas tecnologías se articula como factor decisivo para la activación de resiliencias, potenciando los actos colectivos y la construcción de estrategias comunicativas que permiten la reorientación de las adversidades sociales ante las que se enfrentan.
Artificial intelligence and cities: The global race to regulate algorithms
Authors:   Research Fellow, Global Cities Programme, CIDOB, Galceran-Vercher Marta
Published: March 2023

There is a growing need to ensure that fundamental rights are not compromised by the development and use of artificial intelligence (AI) applications. A global race to set the standards that should govern and regulate AI is underway between global powers, forums and organisations, as well businesses and public and private institutions. The fragmentation of the global regulatory environment has led cities to position themselves as influential normative actors. Cities take on regulatory roles both individually, by developing local governance standards and initiatives, and collectively, within the frameworks of city alliances like CC4DR and Eurocities.

La diversidad de la herpetofauna en la Amazonía peruana tiene un potencial considerable para la conservación, investigación y ecoturismo. Especialmente cuando la pérdida de especies ha aumentado debido al incremento de las actividades antropogénicas. La falta de conocimientos sobre especies de anfibios y reptiles en zonas periurbanas nos motivó a realizar esta investigación en el Centro de Investigación Fernando Alcántara Bocanegra (CIFAB), en Iquitos, Perú, realizamos muestreos cortos y esporádicos de transectos y trampas de caída entre los meses de junio y septiembre de 2021 en pequeños parches de bosque de arena blanca. Reportamos la presencia de especies raras de anfibios (tres especies) y ofidios (una especie): Pristimantis padiali, Ranitomeya amazonica, Synapturanus sp. "nanay" y Micrurus filiformis. Estos registros son importantes por su rareza en las colecciones herpetológicas del país, particularmente el de Synapturanus sp. "nanay" por sus hábitos fosoriales y por ser una especie aún no descrita, y M. filiformis representa el segundo registro para Iquitos después de 45 años. La diversidad de especies raras en el parche periurbano del CIFAB demuestra que a pesar de su ubicación y de la presión antropogénica del medio, este tipo de parche en la Amazonía es de vital importancia para la preservación de especies.
The center for the treatment of sudden cardiac death: the results of five years of work
Authors: Teplov V. M. , Prasol D. M. , Kolomoytsev V. V. , Arkhangelsky N. D. , Bagnenko S. F.
Published: March 2023

The objective was to summarize the Center's experience in the treatment of sudden cardiac death and to assess the prospects of using venoarterial extracorporeal membrane oxygenation (VA ECMO) in the complex of extended cardiopulmonary resuscitation (CPR).

Materials and methods.  109 patients aged 52.6±1.5 years, delivered  to the hospital  by emergency  medical teams with a background of ongoing cardiopulmonary resuscitation.

Results. In the majority of cases (78), extended resuscitation measures were ineffective, ECMO was not used due to inadequate technology connection criteria. In 15 cases, primary stabilization without ECMO was achieved, and these patients were transferred for further treatment to intensive care unit (ICU), 8 of them died later. Extracorporeal cardiopulmonary resuscitation (ECPR) was used in 16 cases, in 6 cases, patients were decannulated after cardiac recovery; also, ECMO was used postmortem 15 times to preserve donor organs. The overall survival rate among the delivered to the Center was 7.5%. We found out the correlation between the duration of the prehospital period and survival rate (time to hospital admission in survivors was 42.7±9.6 min versus 64.31±3.13 min in the deceased). The association between pH (AUC ROC 0.728) on admission and favorable outcome was found to be more reliable than EtCO2 (0.266) and blood lactate  (0.387).

Conclusion. The creation of centers for the treatment of patients with refractory circulatory arrest seems reasonable on the basis of level 3 hospitals with the possibility  of using X-ray surgical methods  of treatment. The widespread  introduction of ECPR should be accompanied  by the change of CPR  algorithms  in the prehospital period. The effectiveness of ECPR is determined by mandatory strict  adherence  to the connection criteria, which can be revised as experience accumulates.
Problems of expert assessment of medical care
Authors: Shapovalov K. G. , Sumin S. A.
Published: March 2023

Legal pressure on the medical worker is currently a factor in reducing  the prestige of the medical profession. An unfair assessment of the quality of medical care leads to a simplification of approaches to the implementation of legally «risk» treatment technologies and the degradation of healthcare. Significant problems are the insufficient formation of competencies among specialists involved in expert work, and gaps in the enforcement of clinical recommendations. Professional medical non-profit organizations have leverage to improve the situation. The elimination of these shortcomings will contribute to an objective and fair legal interpretation of the actions of a medical worker in medical care.

The interaction of a multidisciplinary team was demonstrated, the features of decision-making when choosing a hemodynamic support  method, the complications that  arose and possible difficulties were described.
Pharmacological methods for blood stabilization in the extracorporeal circuit (review of literature)
Authors: Mendibaev M. S. , Rabotinsky S. E.
Published: March 2023

We summarize the possible benefits and risks of using various anticoagulants during hemoperfusion. Clotting in the extracorporeal circuit can lead to a decrease in the effectiveness of therapy,  additional workload,  risk to the patient and economic losses. At the same time, relatively excessive anticoagulation against the background of existing hemostasis  disorders  can lead to severe hemorrhagic complications, which in turn  worsen the prognosis of patients. The article describes the causes of heparin resistance, the main techniques for overcoming it, and provides practical guidelines for anticoagulant therapy during hemoperfusion. It is well known that routine methods of monitoring hemostasis (such as platelet count, activated partial thromboplastin time) are unable to assess the balance of pro/anticoagulants. The authors have proposed a reasonable personalized approach to anticoagulant therapy  of extracorporeal blood purification depending  on the pathology  in patient and thromboelastography (TEG) data, and antithrombin III levels.
СЕМАНТИКО-ПРАГМАТИЧНІ ВІДНОШЕННЯ МІЖ СКЛАДНИМИ ТЕРМІНАМИ-ІМЕННИКАМИ З ЕЛЕКТРИЧНОЇ ІНЖЕНЕРІЇ
Authors: КАРАЧУН Юлія , БОРКОВСЬКА Інна
Published: March 2023

Сьогодні, в епоху технологічного буму та стрімкого розвитку надсучасних технологічних винаходів, лексичний рівень науково-технічної літератури, зокрема з електричної інженерії, активно поповнюється новими одиницями. Це в основному терміни, вживані на позначення предметів, приладів та пристроїв, назв частин цих предметів та пристроїв, процесів, явищ, одиниць вимірювання, назв професій тощо в аналізованій галузі. Обов’язковим компонентом лексичного складу текстів з електричної інженерії є складні термінологічні одиниці, зокрема іменникового типу, які аналізуватимемо в представленій праці з погляду семантики й прагматики та в контексті їхньої пов’язаності чи чіткого розмежування. Її метою було з’ясувати, що є первинним в процесі творення нового складного терміна-іменника: семантика чи прагматика і як вони взаємодіють у структурі лексичного значення термінологічної одиниці. Аналіз теоретичного матеріалу впевнив нас у думці, що всіх учених стосовно погляду на цю проблему можна об’єднати в три групи. Представники першої з них уважають, що семантика є основною, панівною, а прагматика – всього лише її продовженням під назвою постсемантика. Натомість представники другої заперечують наявність будь-якого зв’язку між цими поняттями, обґрунтовують їхню незалежність одне від одного. Третя ж група науковців наполягає на повній взаємозалежності семантики та прагматики. Опираючись на проведений аналіз вилучених з англомовних науково-технічних текстів із електричної інженерії термінологічних одиниць іменникового типу, насамперед їхньої семантики й прагматики, дотримуємося в своєму дослідженні поглядів останньої групи науковців, є її прихильниками й уважаємо семантику та прагматику термінів єдиним, неподільним монолітом. Це можна пояснити тим, що розуміння будь-якої лексичної одиниці, зокрема складного терміна-іменника, відбувається завдяки одночасного сприймання, аналізування та розуміння реалії, тобто за рахунок одночасному використанню реципієнтом як семантичного, так і прагматичного знань.
Missing heritability paradox in schizophrenia: hypothesis and plausible clues
Authors: Thyloor Rama , Nagamani Tandaga Satyanarayana , Gowtham Hittanahallikoppal Gajendramurthy , Kumar Halagur Bhogegowda Kiran
Published: March 2023

Genetic research on schizophrenia, a common psychiatric disease with complex etiology and high (56-80%) heritability, has failed to identify causal genes, variants or causative mechanisms. Given the extensive effort and limited success to date, it is imperative to review potential reasons for this missing heritability. We argue that a successful elucidation of hereditary mechanisms in schizophrenia will likely involve; the identification of discrete endophenotypes; attention to the role of neurodevelopment and cell differentiation; consideration of the genome structure including temporal and spatial patterns, accommodation of environmental effects at the level of gene expression including any sex differences and pattern of mutations including de novo events and the use of analytic techniques that go beyond genome wide association studies. Identification of the heritable component of schizophrenia and sources of “missing heritability” is needed to understand the cause/s of the disorder and to facilitate the development of effective corrective and possibly preventive measures.

Published: March 2023

La presente investigación analiza las disparidades territoriales a escala interregional a través de la aproximación y construcción del Índice de Desarrollo Regional Latinoamericano (IDERE LATAM) para el caso ecuatoriano. El índice está constituido por ocho dimensiones, algunas de ellas no tradicionales, que lo destaca con respecto a otros índices. Los resultados sugieren que, a nivel global, el desarrollo es medio, medio alto y alto; específicamente, Galápagos y Azuay presentan los niveles de desarrollo más elevados. El análisis de las diferentes dimensiones permitió identificar que las brechas interregionales son marcadas en medio ambiente y bienestar y cohesión; son moderadas en economía, educación, instituciones, seguridad y género; mientras que, son reducidas en salud. En general, las provincias reflejan los mejores niveles de desarrollo en educación, salud y género. Por el contrario, los peores desempeños se localizan en economía e instituciones; ambiente también tiene un bajo desarrollo (con la excepción de Galápagos).

The formation of a unique paradigm of religious Existentialism in the poetry of Fyodor Tyutchev
Authors: Mysovskikh Lev Olegovich
Published: March 2023

The philosophical nature of Tyutchev's poetry was noted by researchers of his work during the poet's lifetime. The study of Tyutchev's work makes it possible to trace the origin of a unique direction of philosophical thought in Russian poetry of the XIX century – religious existentialism. The research carried out within the framework of this article allowed us to trace the genesis of the original direction of religious existentialism in the poetry of F. Tyutchev, who interpreted Nature in his work in philosophical categories. In his poetic works, Tyutchev does not just depict the splendor of Nature, but shows his own idea of the essence of the universe and tries to solve the riddle of human existence through the knowledge of the secrets of Nature, which is presented as proof of the existence of God. Thus, Tyutchev's poetry of Nature is regarded as existential poetry, since it gives a person an answer to the question of the meaning of his existence. In Tyutchev's poetry, the tragedy of human existence correlates with a similar theme developed in the philosophical treatises of the founder of existentialism, S. Kierkegaard, and subsequently continued in the works of the German existential philosopher K. Jaspers. Kierkegaard imagined a gloomy reality where a person is doomed to exist, plunged into the abyss of despair. At the same time, the founder of existentialism offered man a way out of tragic existence through the process of self-improvement, that is, the formation of his own personality, and striving for God. However, the process of becoming a personality is also a path to the tragedy of being, as it leads to a violation of harmony between man and Nature. It is this existential problem, which is related to the borderline situation of Jaspers, that lies in the focus of Tyutchev's attention, who described in poetic form the relationship between man and Nature and showed the only possible way out of this situation through making an existential choice in favor of accepting faith in the true God.

Untuk memperoleh data dalam mengevaluasi kebijakan ini didapat dari data holistic yang terdiri dari jumlah penduduk miskin dan Indeks Desa Membangun (IDM). Sementara analisis data yang dilakukan menggunakan metode deskriptif dengan membagi menjadi 6 (enam) wilayah besar di Indonesia yaitu Sumatera, Jawa dan Bali, Maluku dan Nusa Tenggara, Sulawesi, Kalimantan, serta Papua. Hasil penelitian menunjukkan bahwa selama lima tahun dana desa mengalami peningkatan drastis. Kondisi tersebut juga beriringan dengan menurunnya angka kemiskinan sekitar 15% dari tahun 2017 hingga 2021 di Indonesia. Sementara itu, status IDM berdasarkan provinsi juga menunjukkan peningkatan dari yang awalnya desa tertinggal di tahun 2017 menjadi desa berkembang di tahun 2021. Wilayah Jawa dan Bali merupakan wilayah yang berkontribusi paling besar dalam meningkatkan status IDM tersebut baik itu desa berkembang, maju ataupun mandiri. Sedangkan Papua adalah wilayah yang masih memiliki jumlah desa tertinggal terbanyak di Indonesia.
Jean-Baptiste de Lamarck (1744–1829) und 150 Jahre 'Lamarckismus'. Zur Geschichte entwicklungsphysiologisch orientierten Evolutionsdenkens
Authors: Battran Martin
Published: March 2023

Jean-Baptiste de Lamarck gilt als "fondateur de la doctrine de l'évolution" (1809). Sein Transformationskonzept war Basis eines vielgestaltigen Lamarckismus, der – als Gegenentwurf zum ultra-selektionistischen Neo-Darwinismus – v.a. im deutschen Sprachraum reüssierte. Das lamarckistische Prinzip lautet: Die Umwelt hat im Evolutionsgeschehen primär Instruktions-, nicht Selektionsfunktion. Stammesgeschichtlicher Formenwandel beginnt mit gerichteten Entwicklungsänderungen ("arrival of the fittest"), die milieuunabhängig transgenerational rekonstruierbar sind; eine derartige "Vererbung erworbener Eigenschaften" (VEE) verknüpft Onto- und Phylogenese. Als es bis Mitte der 1930er Jahre immer besser gelang, empirische Befunde angeblich umweltabhängiger erblicher Variabilität mendel- und populationsgenetisch zu deuten, erklärten Neo-Darwinisten jegliche VEE für inexistent – womöglich zu Unrecht: Besseres Verstehen schon längst bekannter und die Kenntnis neuer epigenetischer Entwicklungs- und Vererbungssysteme auf verschiedenen Ebenen biologischer Organisation lassen heute lamarckistisches, d.h. entwicklungsorientiertes Evolutionsdenken in neuem Licht erscheinen.
SOME CLASSES OF INVERSE PROBLEMS FOR MIXED TYPE EQUATIONS OF SECOND ORDER
Authors: Джамалов С. З. , Пятков С.Г.
Published: March 2023

Рассматривается вопрос о корректности в пространствах Соболева обратной задачи определения функции источника для уравнения смешанного типа второго порядка. В качестве условий переопределения рассматриваются значения решения на некотором наборе плоскостей размерности n-1. Неизвестные функции, входящие в правую часть, зависят от времени и n - 1 пространственных переменных и ищутся в классе квадратично суммируемых функций. При определенных естественных условиях на данные получены теоремы существования и единственности обобщенных решений задачи. Условия на данные по существу совпадают с условиями разрешимости прямой задачи. В качестве метода используется метод продолжения по параметру и полученные априорные оценки. Метод исследования позволяет обобщить результаты на случай более гладких данных и регулярных решений.

In the Sobolev spaces, we consider the well-posedness questions for the inverse problem of recovering the source function of a mixed type equation of second order. The overdetermination conditions are the values of a solution on a collection of planes of dimension n - 1. The unknowns occurring in the right-hand side depend on time and n - 1 unknown space variables. Under certain natural conditions on the data of the problem, we obtain existence and uniqueness theorems for generalized solutions to this problem. The conditions on the data almost coincide with those ensuring solvability of the direct problem. The parameter continuation method and a priori estimates are used to validate the results. The method allows us to generalize the results to the case of smoother data and regular solutions.

Исследуется разрешимость начально-краевой задачи для линейных интегродифференциальных уравнений с заданием на боковой границе условия, связывающего значения решения или конормальной производной решения со значениями некоторого интегрального оператора от решения. Доказываются теоремы существования и единственности регулярных решений. В последнее время активно изучаются нелокальные краевые задачи для параболических и гиперболических уравнений с интегральными условиями на боковой границе, но при этом в основном рассматривается лишь случай классических уравнений второго и четвертого порядков. Начало систематических исследований нелокальных краевых задач - задач нахождения периодических решений для эллиптических уравнений - было положено в статье А. В. Бицадзе и А. А. Самарского (1969). Отметим также исследования для псевдопараболических и псевдогиперболических уравнений третьего порядка с интегральным условием на боковой границе. Большой вклад в развитие теории нелокальных задач для дифференциальных уравнений различных классов внесли монографии А. Л. Скубачевского (1997) и А. М. Нахушева (2006, 2012).

We study the solvability of the initial-boundary value problem for linear integro-differential equations with a lateral boundary condition correlating values of the solution or its conormal derivative with values of some integral operator on the solution. We prove existence and uniqueness theorems for regular solutions. Recently, nonlocal boundary value problems for parabolic and hyperbolic equations with integral conditions on the lateral boundary are intensively studied, primarily in the classical case of second- and fourth-order equations. The systematic study of nonlocal boundary value problems, the problems of finding periodic solutions to elliptic equations, began in the article by A. V. Bitsadze and A. A. Samarskii (1969). A great contribution to the development of the theory of nonlocal problems for differential equations of various classes was made by A. L. Skubachevsky (1997) and A. M. Nakhushev (2006, 2012).

Рассмотрены задачи фильтрации в трещиноватых средах, которые необходимы при моделировании процессов извлечения углеводородного сырья из нетрадиционных коллекторов, разработки геотермальных месторождений, подземного захоронения радиоактивных отходов в водоносных коллекторах и др. Сети трещин в таких нефтяных месторождениях могут существовать на различных масштабах, а также различаться природой их возникновения. В данной статье рассмотрена математическая модель фильтрации жидкости в трещиноватых пористых средах, описываемая связанной системой уравнений смешанной размерности с заданием специальной функции перетока. Аппроксимация задачи строится с помощью метода конечных разностей на структурированных сетках с использованием встроенной модели трещин, что позволяет строить сетки для матрицы пористой среды независимо от сетки для трещин. Построение консервативной разностной схемы приводится для матрицы пористой среды с использованием интегро-интерполяционного метода и обобщается для связанной системы уравнений, описывающих математические модели мультиконтинуума с иерархическим представлением сети трещин. Представлены результаты численного исследования модельной двумерной задачи.

We consider filtration problems in the fractured media that are necessary when modeling the processes of extracting hydrocarbons from unconventional reservoirs, geothermal fields development, underground disposal of radioactive waste in aquifers, etc. Fracture networks in such oil pools can exist on different scales and differ in the nature of their occurrence. We discuss a mathematical model of ﬂuid filtration in fractured porous media described by coupled equations of mixed dimension with assigning of a special ﬂow function. The problem approximation is constructed through the finite difference method on structured grids using the embedded fracture model, which makes possible creating grids for the porous medium matrix independently of the fracture network grid. The construction of a conservative difference scheme is given for the matrix of porous medium with the use of an integro-interpolation method and generalized for coupled equations describing mathematical models of multicontinuum with hierarchical representation of fracture networks. The results of the numerical implementation of the two-dimensional model problem are presented.

Authors: Мамчуев М.О.
Published: March 2023

Исследуется нелокальная краевая задача в прямоугольной области для линейной системы уравнений с частными производными дробного порядка в смысле Римана-Лиувилля с постоянными коэффициентами. Знакоопределенность собственных значений матричных коэффициентов в главной части является существенным признаком таких систем, и эти системы можно разделить на два разных типа, которые заметно отличаются в плане постановок корректных краевых задач. Исследуемая система относится к типу II, т. е. к системам с собственными значениями матричных коэффициентов в главной части разных знаков. Доказана теорема о существовании и единственности решения исследуемой краевой задачи. Получены условия однозначной разрешимости исследуемой задачи в терминах собственных векторов матричного коэффициента в главной части системы.

We study a non-local boundary value problem in a rectangular domain for a linear system of equations with partial fractional Riemann-Liouville derivatives with constant coefficients. The eigenvalues of matrix coefficients in the main part have fixed sign, which is an essential feature of such systems. These systems can be divided into two types which differ in terms of formulation of the correct boundary value problems. The system under investigation relates to the type II, i.e. to systems with the eigenvalues of matrix coefficients in the main part having different signs. We prove the existence and uniqueness theorem for the solution of the investigated boundary value problem. The conditions for the unique solvability of the problem are obtained in terms of the eigenvectors of the matrix coefficients in the main part of the system.

Authors: Lazarev N. , Tani A. , Sivtsev P.
Published: March 2023

We consider equilibrium problems for a cracked inhomogeneous plate with a rigid circular inclusion. Deformation of an elastic matrix is described by the Timoshenko model. The plate is assumed to have a through crack that reaches the boundary of the rigid inclusion. The boundary condition on the crack curve is given in the form of inequality and describes the mutual nonpenetration of the crack faces. For a family of corresponding variational problems, we analyze the dependence of their solutions on the radius of the rigid inclusion. We formulate an optimal control problem with a cost functional defined by an arbitrary continuous functional on the solution space, while the radius of the cylindrical inclusion is chosen as the control parameter. Existence of a solution to the optimal control problem and continuous dependence of the solutions with respect to the radius of the rigid inclusion are proved.

We consider solving the problems of predicting changes in the defining characteristics of composite materials and structures under the inﬂuence of extreme environmental factors. As such determining characteristics, we can take the residual life, reliability, and durability of composite materials and structures. We study the application of combined methods for finding the extremum of multiparametric performance indicators for solving inverse problems of predicting the determining characteristics of composite materials and structures based on complicated models. The question of the most effective design of the combined approaches by implementing several methods for the solution of inverse problems of forecasting the defining characteristics of composite materials and designs is investigated.
Zinc Bromide: A General Mediator for the Ionothermal Synthesis of Microporous Polymers via Cyclotrimerization Reactions

Published: March 2023

Conjugated microporous polymers (CMPs) are porous organic materials that display (semi)conducting behavior due to their highly -conjugated structures, making them promising next-generation materials for applications requiring both electrical conductivity and porosity. Currently, most CMPs and related porous aromatic frameworks (PAFs) are prepared using expensive transition metals (e.g., Pd), significantly increasing the costs associated with their synthesis. Lewis acid-mediated cyclotrimerization reactions of methyl ketones and nitriles represent promising and green alternative methods for CMP and PAF synthesis. Herein, we demonstrate that the generality of the solvent-free cyclotrimerization reactions is significantly improved by using ZnBr2 instead of ZnCl2 as the ionothermal medium. Specifically, we show that 1,4-diacetylbenzene (DAB), 4,4-diacetylbiphenyl (DABP), 2,7-diacetylfluorene (DAF), 1,3,5-triacetylbenzene (TAB), tetrakis(4-acetylphenyl)methane (TAPM), and 1,4-dicyanobenzene (DCNB) can be polymerized in molten ZnBr2 to produce highly conjugated and microporous materials, as confirmed by 77 K N2 adsorption measurements, IR, and solid-state NMR. These findings support that ZnBr2 is an excellent Lewis acid mediator and medium for the ionothermal synthesis of porous organic materials.
A route for long-term DNA preservation through nanoconfinement in smectites

Published: March 2023

Traces of DNA found in sediments are shifting paradigms in the analysis of past and present ecosystems. DNA is an unstable polymer and conditions at which the millennial stabilization is achieved are unclear. Confinement of DNA in nanopores of clay minerals is a promising route for this long-term stabilization and storage. Using smectites with various layer charges, we measured adsorption capacity for DNA using UV spectroscopy and intercalation capacity using X-ray diffraction. We found that while the smectite adsorption capacity is large, the DNA intercalation, i.e. nanoconfinement, decreases as smectite charge increases. We show that low-charge smectites intercalate DNA at concentrations relevant to aqueous environments even at neutral pH but the nanoconfinement is minimal or absent in high-charge smectites. Different intercalation behaviour in NaCl and CaCl2 solutions imply different mechanisms driven by electrostatic forces. Our results demonstrate that DNA nanoconfinement in smectites is likely an important strategy for DNA preservation and that protocols targeting low-charge smectites might improve the success of ancient and modern DNA extraction even in hot and humid climates so far deemed unfavourable for DNA preservation.

In the fields of sanitation and medicine, there is an urgent need for the development of convenient methods for imparting antibacterial properties to materials. Polypropylene nonwoven fabrics (PP NWFs) are one of the most common polymer materials; however, it is difficult to impart antibacterial properties to PP NWFs due to their low reactivity and complicated structures. In this study, we discovered that oxidation using photo-activated chlorine dioxide radical (ClO2) gas is a useful method for antibacterial modification of PP NWFs, without the need for any antibacterial agents or multi-step treatments. The as-prepared PP NWFs exhibited excellent antibacterial activity against both Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive). Interestingly, the solvent used to wash the product was analyzed to reveal the formation of nanoparticles around 80 nm in diameter during the oxidation step, particularly at 80 C.
