Authors: Сенин Л.Н. , Сенина Т.Е.
Published: July 2024

Проведение малоглубинных сейсмических исследований методом преломленных волн (МПВ) на участках под строительство зданий и сооружений различного назначения обеспечивает по- лучение значительного объема выходных данных, которые используются, прежде всего, по своему пря- мому назначению: во-первых, построение скоростных разрезов МПВ, что дает возможность оценки структурных особенностей верхней части геологического разреза, во-вторых, получение массива ско- ростных данных вдоль сейсмического профиля, причем как массива скоростей продольных волн VP, так, зачастую, и поперечных вертикальной поляризации VSV. Примером тому могут служить результаты профильных работ на площадке в районе п. Таватуй Свердловской области. Заметим, что получение волн SV-типа значительно рентабельнее в плане производства полевых наблюдений, по сравнению с методикой получения поперечных волн горизонтальной поляризации SН-типа. Кроме применения, полученного при производстве МПВ банка данных скоростей по своему прямо- му назначению, информацию можно с успехом использовать для расчетов сейсмических жесткостей в сейсмическом микрорайонировании исследуемых участков, что и было сделано для площадки под строительство жилого дома в районе п. Таватуй Свердловской области.

Conducting shallow seismic studies by the method of refracted waves (Refracted waves) at sites for the construction of buildings and structures for various purposes provides a signifi cant amount of output data that are used primarily for their intended purpose: fi rstly, the construction of velocity sections of the refracted waves, which makes it possible to estimate structural features of the upper part of the geological section, and secondly, obtaining an array of velocity data along the seismic profi le, both the array of the velocities of the longitudinal waves VP, and, often, transverse vertical polarization VSV. An example of this is the results of profi le work at the site in the area of the village of Tavatui, Sverdlovsk region. Note that obtaining SV-type waves is much more cost-effective in terms of fi eld observations, in comparison with the method of obtaining transverse waves of horizontal polarization SH-type. In addition to using the velocity databank obtained during the production of refractory materials for its direct purpose, the information can be successfully used to calculate seismic stiffness in seismic microzoning of the studied areas, which was done for the site for the construction of a residential building in the area of the village of Tavatui, Sverdlovsk region.

Authors: Шестаков А.Ф.
Published: July 2024

Работа посвящена развитию континуального подхода к решению прямых граничных задач электродинамики. В работе рассмотрены некоторые аспекты решения задачи рассеяния переменного электромагнитного поля, возбуждаемого в гармоническом режиме, на локальном объекте неоднородно- сти в отношении электрических и магнитных свойств. В отличие от традиционного подхода, базирующегося на представлении решения задач для отдельных областей и последующего их «сшивания» с использованием естественных условий сопряжения эле- ментов поля на границе области, подход основан на решении задачи во всем пространстве с учетом вторичных источников поля, возникающих в градиентных зонах изменения материальных параметров среды.

The work is devoted to the development of a continuum approach to solving direct boundary problems of electrodynamics. Some aspects of solution of problem of scattering of alternating electromagnetic fi eld excited in harmonic mode on local object of non-homogeneity in relation to electric and magnetic properties are considered in the work. Unlike the traditional approach, based on the presentation of the solution of problems for individual areas and their subsequent “stitching” using the natural conditions for the conjugation of fi eld elements at the boundary of the area, the approach is based on the solution of the problem in the entire space, taking into account secondary fi eld sources that arise in gradient zones of change in material parameters of the medium.

Authors: Иголкина Г.В.
Published: July 2024

Определение элементов залегания намагниченных тел, подсеченных сверхглубокими скважинами, решает важную геологическую задачу по оценке пространственного положения пород в околоскважинном пространстве, так как никакие другие методы геофизических исследований скважин (ГИС) не располагают такими возможностями оценить элементы залегания горных пород в естественном залегании по разрезу скважин. Решение этой задачи по трем стволам Кольской сверхглубокой скважины СГ-3 позволило построить достоверный геолого-геофизический разрез, который нашел подтверждение по геологическим данным. Кроме того, установлено, что залегание двух эффузивных толщ, вскрытых Саатлинской сверхглубокой скважиной, различное. Впервые определены элементы залегания зон пирротиновой минерализации в Мурунтауской СГ-10 и оценена возможность метода скважинной магнитометрии для решения в сложных геологических условиях.

Determination of the elements of occurrence of magnetized bodies clipped by ultra-deep wells solves an important geological problem of assessing the spatial position of rocks in the downhole space, since no other methods of geophysical well surveys (GIS) have such capabilities for assessing the occurrence of rocks in the natural occurrence along the well site. The solution of this problem for the three trunks of the Kola superdeep well SG-3 allowed us to build a reliable geological and geophysical section, which was confirmed by geological data. In addition, it was found that the occurrence of two effusive layers opened by the ultra-deep Saatli well is different. For the first time, the elements of the occurrence of pyrrhotite mineralization zones in Muruntau SG-10 were determined and the possibility of using the borehole magnetometry method to solve problems in difficult geological conditions was evaluated.

Решена обратная задача по определению координат и времени источника возникновения сферической волны по множеству станций наблюдений (обратная четырехмерная засечка). Выполнено тестирование полученного решения при различном уровне помех. Обратная четырехмерная засечка, может применяться в навигационных системах, геодезии и сейсмологии. Полученное решение применено для глобального сейсмического каталога и найдено распределение вероятных источников возбуждения деформаций внутри Земли. Основное число сингулярных источников сферических деформационных фронтов сосредоточено в ядре Земли (R<3000 км -93,7 %). Выделены отдельные кластеры источников вероятных деформаций и построены разрезы Земли с распределением сингулярных источников первичных деформаций. Применение обратной четырехмерной засечки для найденного каталога источников первичных сингулярных деформаций дает с хорошей точностью распределение исходных землетрясений в земной коре и верхней мантии.

The inverse problem is solved to determine the coordinates and time of the source of the spherical wave from many observation stations (inverse four-dimensional mark). The resulting solution was tested at different interference levels. The inverse four-dimensional mark can be used in navigation systems, geodesy and seismology. The resulting solution was applied to the global seismic catalog and the distribution of probable sources of deformation excitation inside the Earth was found. The main number of singular sources of spherical deformation fronts is concentrated in the Earth’s core (R < 3000 km -93,7%). Separate clusters of sources of probable deformations are identified and Earth sections with distribution of sources of primary deformations are constructed. The application of the inverse four-dimensional notch to the found catalog of sources of primary singular deformations gives with good accuracy the distribution of the original earthquakes in the Earth’s crust and upper mantle.

Authors: Овчаренко А.В.
Published: July 2024

Глобальная деформационная модель по предлагаемой методике строиться в два этапа. На первом этапе, в предположении волновой природы сейсмичности, строится модель первичных син- гулярных источников деформационного процесса. Для этого применяется алгоритм прямой локации семейства источников деформационных волн по глобальному сейсмическому каталогу или по каталогу комплексных геодинамических индикаторов. На втором этапе, на основе решения линейной обратной задачи, семейство сингулярных источников наделяется амплитудными характеристиками. Для этого используются мировые каталоги скоростей GPS/GNSS, на основе которых ставится и решается линей- ная обратная задача. Таким образом, было построено семейство первичных сингулярных источников возможных деформационных фронтов для Земли. Основная масса этих источников сосредоточена вну- три ядра (R<3000 км, 93.7 %). Применение обратной четырехмерной засечки для найденного множе- ства источников первичных сингулярных деформаций позволяет восстановить с хорошей точностью исходный каталог землетрясений в земной коре и верхней мантии. Даются формулы для расчета всех элементов тензора деформаций и трех главных инвариант деформационного тензора. Описан способ снижения размерности обратной линейной задачи. Изучается структура полученного решения путем расчета различных элементов динамического деформационного тензора.

The global deformation model according to the proposed method is built in two stages. At the fi rst stage, under the assumption of the wave nature of seismicity, a model of primary singular sources of the deformation process is built. To do this, the algorithm of direct location of the family of sources of deformation waves on the global seismic catalog or on the catalog of complex geodynamic indicators is used. At the second stage, based on the solution of the linear inverse problem, the family of singular sources is endowed with amplitude characteristics. For this, world directories of GPS/GNSS speeds are used, on the basis of which a linear inverse problem is set and solved. Thus, a family of primary singular sources of possible deformation fronts for the Earth was built. The bulk of these sources are concentrated inside the core (R < 3000 km, 93.7%). The use of inverse four-dimensional serifs for the found set of sources of primary singular deformations makes it possible to restore with good accuracy the original catalog of earthquakes in the earth’s crust and upper mantle. Formulas are given for calculation of all elements of strain tensor and three main invariants of strain tensor. Described is a method of reducing the dimension of an inverse linear problem. The structure of the resulting solution is studied by calculating various elements of the dynamic strain tensor.

Published: July 2024

Выполнено изучение Катав-Ивановского грязевого оползня геофизическими методами по двум профилям в эпицентральной зоне одноименного землетрясения (5.09.2018, М5.8). Применялся комплекс методов: магнитометрия, многочастотное электромагнитное профилирование, аудиомагнитотеллурическое зондирование (АМТЗ). Получены глубинные разрезы намагниченности, кажущегося сопротивления и проводимости. Выявлена система суб- вертикальных тектонических нарушений и субгоризонтальные границы коры выветривания и обводненной зоны трещиноватости. Тектонические нарушения проявлены положительными аномалиями магнитного поля (20–60 нТл), узкими зонами (10–20 м) пониженного электрического сопротивления горных пород, повышенной электрической проводимостью и поверхностными трещинами в бортах оползня. Глубина границы коры выветривания по данным АМТЗ и инверсии магнитного поля в намагниченность среды составляет 10–20 м, а обводненной зоны трещиновато- сти 60–75 м. В коре выветривания имеются глубокие карманы в зонах тектонических нарушений. Оползень является наиболее вероятным местом тектонического удара Катав-Ивановского земле- трясения с разрывом сплошности геологической среды.

The study of the Katav-Ivanovsky mud landslide by geophysical methods was carried out along two profi les in the epicentral zone of the same named earthquake (09/05/2018, M5.8). Magnetometric survey, multi-frequency electromagnetic profi ling with AEMP-14 equipment and audio magnetotelluric sounding was used. Deep sections of magnetization, apparent resistance and conductivity are obtained. A system of sub-vertical tectonic faults and sub-horizontal boundaries of the weathering crust and the fl ooded fracture zone were revealed. Tectonic disturbances are manifested by magnetic fi eld anomalies of 20-60 nT, narrow zones (10-20 m) of reduced electrical resistance of rocks by 3000-3500 ohm·m, contacts of blocks of different (by 100-200 ohm·m) electrical resistance, increased electrical conductivity and surface cracks in the sides of the landslide. The boundary depth of the weathering crust according to audio magnetotelluric sounding and the inversion of the magnetic fi eld into the magnetization is 10–20 m, and the depth of the watered fracture zone is 60–75 m. There are deep pockets in the weathering crust in zones of tectonic faults. The landslide is the most probable place of the tectonic impact of the Katav-Ivanovsk earthquake with a break in the continuity of the geological environment.

Published: July 2024

Целью работы являлось изучение особенностей размещения и локализации рудопроявлений меди в пермских отложениях осадочного чехла Предуральского краевого прогиба, передовых складок Урала и восточной части Русской платформы относительно радиально-концентрических структур, выявленных по результатам дешифрирования космических фотоснимков, сейсмотектоническим и геоморфологическим данным. Исследования показали, что в строении, распределении и локализации месторождений меди в пермских отложениях есть много общего с размещением залежей углеводородов. Месторождения имеют пластовую и линзовидную форму залежей, субгоризонтальное залегание, латерально-вертикальную зональность, многоярусное строение продуктивных толщ, приуроченность к соляной тектонике, цветковым и радиально-концентрическим структурам. Сделан вывод о том, что, возможно, их объединяет общий генезис, связанный с современными геодинамическими процессами в земной коре. Месторождения медистых песчаников в надсолевых отложениях могут быть продуктом вертикальной миграции гидротермальных растворов по неотектоническим разрывным нарушениям из глубоких горизонтов.

The aim of this work was to study the distribution and localization of copper ore occurrences in the Permian deposits of the sedimentary cover of the Cis-Ural foredeep, the frontal folds of the Urals and the eastern part of the Russian Platform with respect to radial-concentric structures identifi ed by the results of interpretation of space photographs, seismotectonic and geomorphological data. Studies have shown that in the structure, distribution and localization of copper deposits in Permian deposits, there is much in common with the location of hydrocarbon deposits. The deposits have a sheet and lenticular form of deposits, subhorizontal occurrence, lateral-vertical zoning, a multi-tiered structure of productive strata, confi nement to salt tectonics, fl oral and radialconcentric structures. It is concluded that, perhaps, they are united by a common genesis associated with modern geodynamic processes in the earth’s crust. Deposits of cupriferous sands in post-salt deposits may be the product of vertical migration of hydrothermal solutions along neotectonic faults from deep horizons.

Published: July 2024

The development of new thermoplastic-based nanocomposites for, as well as using, 3D printing requires extensive experimental testing. One typically goes through many failed, or otherwise sub-optimal, iterations before finding acceptable solutions (e.g. compositions, 3D printing parameters). It is desirable to reduce the number of such iterations as well as exclude failed experiments that often require laborious disassembly and cleaning of the 3D printer. This issue could be addressed if we could understand, and ultimately predict ahead of experiments, if a given material can be 3D printed successfully. Herein, we report on our investigations into forecasting the printing and resultant properties of polymer nanocomposites while encompassing both material properties and printing parameters. To do so, nanocomposites of two different commercially available bio-based PLAs with varying concentrations of nanoclay (NC) and graphene nanoplatelets (GNP) were prepared. The thermal and rheological properties of the nanocomposites were analyzed. These materials were printed at varying temperature and flow using a pellet printer. Each time, three identical cylindrical-shaped samples were printed, and to assess the printing quality, the variation in weight and geometrical factors were determined. The interactions between material properties and printing parameters are complex but can be captured effectively by a machine learning model. Specifically, we demonstrate such a predictive model to forecast print quality utilizing a Random Forest algorithm.
Reactivity of Pseudozyma antarctica lipase B towards the Synthesis of End-capped Polycaprolactone for Drug Delivery
Authors: R. Figueiredo Pedro , J.D. Silvestre Armando , F. Sousa Andreia , T.P. Carvalho Alexandra
Published: July 2024

State-of-the-art delivery systems currently rely on chemical synthesis routes for drug encapsulation. However, these methods have inherent drawbacks concerning toxicity, selectivity, and the potential for burst release. To overcome these limitations, the enzymatic synthesis of polymer-drug conjugates emerges as a promising alternative to promote eco- friendliness and safety in production and grants precise control over the resulting structures. In this study, we delved into the reactivity of Pseudozyma (Candida) antarctica lipase B for polyesters’ capping with small molecules. For that purpose, Quantum Mechanics/Molecular Mechanics simulations were used to predict the conjugation reactions. These predictions were translated to the laboratory, where the enzymatic reactions were replicated, subsequently benchmarking them against metal-catalysed reactions. The outcome of our experiments was the successful generation of end-capped oligo/polycaprolactone, with their molecular weights spanning from 540 to 2600 g mol-1 with an enzymatic approach, and slightly higher when applying conventional catalysis, and with isolation yields up to 68.4%. This work underscores the potential of enzyme-driven strategies in fabricating precisely engineered drug delivery systems, marking a significant stride toward more efficient and controlled therapeutics synthesis.

Published: July 2024

We report a highly efficient protocol for the synthesis of 3-silyl coumarins using hydrosilanes as the silyl radical source with aryl alkynoates. Readily prepared N-aminopyridinium salts act as hydrogen atom transfer reagents for generating silyl radicals under mild conditions via photoredox catalysis. The reaction proceeds through silyl radical addition to alkyne followed by radical cascade cyclization/migration with subsequent oxidation and aromatization to give desired 3-silyl coumarins in good to excellent yields.

Authors: Liu Lihua , Shen Xiaokun
Published: July 2024

Ciprofol, as a new type of short-acting intravenous anesthetic drug, belongs to the category of gamma-aminobutyric acid (GABA) receptor agonists. Its unique chemical structure, through the introduction of the cyclopropyl group in the isopropyl side chain of propofol, constructs a new type of chiral molecule, which significantly enhances the spatial effect, and improves the affinity for GABA receptors. Its pharmacological properties are characterized by high potency, rapid onset of action, rapid recovery, low accumulation, and minimal adverse reactions. Therefore, it has a wide range of applications in various endoscopic diagnostic and therapeutic operations, ICU sedation, and general anesthesia. In this paper, the related knowledge of ciprofol and the development of clinical application research are comprehensively sorted out and synthesized, to provide a solid theoretical basis for the rational application of ciprofol in clinical practice. At the same time, the future research direction of ciprofol will also be prospected to provide valuable references for research in related fields.

Authors: Wang Guanyang
Published: July 2024

Recently, during the commissioning period of a 350MW DC boiler in a certain power plant, multiple abnormal situations occurred, which are relatively rare. For example, in normal operation, when the oil pressure of the supply fan suddenly rises to 10MPa full range, the moving blades of the supply fan cannot be adjusted, resulting in an automatic decrease in fan output, negative pressure fluctuations, and a decrease in unit load; Oil leakage in the control oil pipe of the air supply fan, causing a decrease in system oil pressure; A large amount of steam leakage occurs in the water valve of the warm valve; Leakage and other issues with the cooling water control valve of the superheater. Serious impact on the safe operation of the unit. Through summary and analysis, the root cause problem was ultimately discovered and thoroughly solved. This article mainly summarizes the analysis of abnormal causes and the sharing of experience in the handling process.

The lakes represent crucial surface water resources and an integral part of wetlands. The most concerning aspect of the degradation of these areas is the complete drying up of the lakes. In the Mediterranean region, successive changes in land use practices in the context of climate change have strongly influenced wetland areas. In this study, we used Landsat TM, OLI, and OLI-2 satellite images to monitor the water surface area in two representative lakes (Aoua and Ifrah) of the Tabular Middle Atlas and to map land use across the entire study area. To extract information related to lakes and land use, we employed the Support Vector Machine machine learning algorithm, widely used in remote sensing studies. However, we identified drought periods from precipitation data using the Standardized Precipitation Index (SPI) recommended by the World Meteorological Organization (WMO). The results obtained from the processing of Landsat satellite images indicate a significant reduction in the surface area of the lakes, with periods of drying for Aoua lake, endangering their fragile ecosystems and biodiversity. The critical situation of the two lakes is attributed to a combination of natural and anthropogenic factors. The analysis of climatic data shows a significant climate change from the 1980s, with long periods of drought. In parallel, the study area has undergone remarkable modifications in land use patterns, mainly characterized by a significant extension of irrigated agricultural surfaces to the detriment of grazing and rainfed lands. In three decades, the area of irrigated crops has increased from approximately 1300 hectares in 1985 to 7070 hectares in 2022, representing an increase of 542%. The findings presented in this study reveal the extent of lake degradation in the TMA and reflect the alarming decline in groundwater levels. This situation indicates the necessity of formulating a strategy to protect water resources and wetlands in the Middle Atlas.
Teaching Implication of Meaning Construction at Morphological Level of Affixation in a Complex Indonesian Verb Formation

Published: July 2024

A tension exists between rationalists and empiricists regarding the nature of knowledge: innate then activated/discovered (rationalists) or constructed then invented (empiricists). The assumption is that, to a certain extent, basic knowledge seems to be innate in our mind and develops through experience by thinking processes to construct meanings. This meaning construction (thinking), mainly using language, is to make sense of and interpret the world. Meanings should be the primary motivation underlying linguistic constructions at all levels. This paper investigates meaning constructions at the lexical level of affixation by focusing on semantic behaviours of verbs in a complex word formation as an attempt: 1) to find out the semantic patterns of verb-based complex word formation, 2) to reveal if there is an iconic relationship of a sign (signifier) and its meaning (signified), and 3) to suggest for its teaching. Using semantic classes of verbs, based on situation types in deriving complex words, this study attempts to find out semantic patterns of such complex word formation and the possibility of revealing its iconicity. Using Antconc software, this study scrutinized linguistic expressions involving related verbs of state, event, and action in a corpus to reveal meaning construction at that level. The findings show several semantic patterns of verb-based complex word formation and an indication of the iconicity of signs. The paper also offers suggestions for teaching affixation

The difficulties faced by teachers at a Special Public School in teaching Balinese script literacy to visually impaired children have resulted in low literacy skills in Balinese script among these students. In order to maximize Balinese script learning, appropriate learning media tailored to the characteristics of visually impaired children are necessary. This study aims to determine the design, feasibility, and effectiveness of the Relief Balinese Script Media (Reaksi) assisted by audio to improve the Balinese script literacy of visually impaired students at a Special Public School. The study utilizes the ADDIE development model with a quantitative research design. Data collection methods include written tests assessing Balinese script writing. The subjects of this study are 12 visually impaired students. The results of this development study are as follows: (1) the design of the audio media achieved a score of 93.15%, qualifying as excellent; (2) the Reaksi media was deemed feasible, scoring 91.44% and qualifying as excellent; (3) the obtained t-value was 77.97, while the t-table value at a significance level of 5% was 2.101. These results indicate that the t-value is greater than the t-table value, thus rejecting H0 and accepting H1. Therefore, it can be concluded that the Relief Balinese Script Media (Reaksi) assisted by audio is effectively applied to improve the Balinese script literacy of visually impaired students at a Special Public School. This audio-assisted Relief Balinese Script Media (Reaksi) helps visually impaired students recognize the actual forms of Balinese script, thereby enhancing the literacy skills of Balinese script reading and writing among visually impaired students.

Metacognition and reading comprehension skills are believed to influence students' academic success. However, many studies report that students' understanding of texts is still low even though they have been able to read fluently. This study aims to investigate and describe students' metacognitive awareness in reading comprehension learning activities and the effect of metacognition on reading comprehension skills. The research method used is a mixed-method by utilizing the descriptive and quantitative correlational analysis results. The research subjects involved were 280 students and eight Indonesian language teachers from eight senior high schools. The research data was obtained from the observations of reading learning activities, interviews, distributing questionnaires, and reading skills tests. The results showed that most students did not know the right reading strategy for themselves. Overall, students have not been able to conclude the goals and benefits of learning to read comprehension for their lives, behave passively in learning, and have not been able to identify solutions to face reading comprehension difficulties according to their characteristics. Based on the results of correlational calculations, metacognition was positively correlated with students' reading comprehension skills. This study recommends that teachers and curriculum designers emphasize the components of metacognitive awareness activity for improving students' reading comprehension skills.
