Synthesis, structural, thermal, and morphological characterization of Ru(III) complex with gatifloxacin and its utility to obtain RuO2 nanostructures
Authors: Althubeiti Khaled 
Published: April 2024

Abstract
In this work, the reaction between the drug gatifloxacin (as a ligand) with Ru(III) ions was investigated and the resulting complex was structurally and morphologically characterized. The structural properties of the complex were assessed using elemental analyses, molar conductance, thermogravimetry, UV-Vis, and IR spectroscopies, where the morphological characteristics were evaluated using SEM-EDX and XRD methods. The analyses suggested that two ligand molecules were coordinated to the Ru(III) ion via the nitrogen atoms of piperazine rings. The complex was formulated as [Ru(L)2(Cl)2]Cl, where the Ru(III) ion has a six-coordinate mode, and the coordination sphere is complemented by chlorine atoms. The interaction of the ligand with the Ru(III) ions leads to the product having an organized smooth plate-like structure with a main diameter of 39.42 nm. The RuO2 oxide in the nanoscale range was generated by the thermal decomposition of the [Ru(L)2(Cl)2]Cl complex at 600 oC for 3 hours. SEM micrographs indicated that the RuO2 material possesses uniform and organized microstructures with many internal cavities enabling it to be used as a catalyst for the heterogeneous degradation of dyes and organic pollutants.

Abstract
Advance chemical oil recovery techniques such as low salinity surfactant polymer (LSSP) flooding possibility of increasing oil recovery has been demonstrated by a number of laboratory experiments. In these and related chemical EOR techniques, sodium hydroxide is used to raise the injection solution's pH and decrease anionic surfactant adsorption. However, more precise surfactant adsorption level estimations is needed in the context of low salinity surfactant polymer (LSSP) flooding. Thus, an integrated geochemical framework is developed to understanding of the geochemical interactions between rocks, oil, and brine, as well as surfactants and polymers. Currently, geochemical reactions involving rock-brine, oil-brine, surfactant-brine, and oil-surfactant are considered by surface complexation models (SCM). Here, we take it a step further and apply the surface complexation geochemical reactions for polymers and coupling them for the first time for geochemical modeling of LSSP flooding.
We compared our model with four distinct experimental data sets from the literature and investigated different parameters affecting surfactant adsorption during LSSP flooding. The adsorption of surfactant and effluent concentration was determined accurately by the coupling of polymer-based surface complexation geochemical reactions. Furthermore, we carried out a thorough simulation analysis, and the results show that raising the chemical flood's temperature decreases surfactant adsorption while raising its concentration in the effluent. Additionally, our analysis shows that because there are stronger repulsive forces between the adsorbed species and the rock surface, surfactant adsorption on the rock surface is reduced when the overall salinity of the water is reduced. Moreover, increasing the concentration of surfactant in the chemical flood causes the concentration of surfactant in the effluent to rise along with a notable increase in surfactant adsorption. We also observed that sulfate spiking has a noteworthy impact, as surfactant adsorption is decreased by an increase in sulfate concentration. Notably, injecting diluted water produced the lowest levels of surfactant adsorption. It is crucial to note that this work is the first to investigate a novel formulation of surface complexation modeling that takes into consideration the influence of interactions between polymer, surfactant, oil, brine, and rock on the adsorption properties of surfactants.
Real-Time Evaluation of the Lost Circulation Zone Based on a Changepoint Analysis of the Mechanical Specific Energy and Standpipe Pressure
Authors: Ruzhnikov Alexey , Guillot Valerian , Corona Mauricio 
Published: April 2024

Abstract
There are multiple mechanisms that may drive a lost circulation event while drilling a well. Efficiently dealing with those events requires that the operations team quickly get an understanding of subsurface conditions that caused the event. Globally, some lost circulation events are cured by basic lost circulation materials (LCM) / bridging, while others fail to be cured even after days of attempts with lost circulation cement plugs (LCP) and novel materials.
The aperture of the lost circulation zone (LCZ) remains unknow in most of the cases unless open hole logs ran to identify it. The standard approach to cure the losses is to start with less aggressive materials followed by more aggressive, and the curing based on the field practices, rather being linked to the potential opening of LCZs.
The manuscript will investigate the hypothesis that the lost circulation events related to penetration of large, connected, open cavities (karsts) can be characterized, and those large open cavities can be identified in near-real time by analyzing the dynamic drilling parameters with help of Machine Learning.
There are different mechanisms that are driving the lost circulation events. Within the same formation some of lost circulation zones can be easily cured with LCM/LCP, others require more effort and time and may be uncurable. The invention proposes a workflow and an algorithm to detect from dynamic drilling parameters what is the likely mechanism at play, and whether the lost zone is curable. Large fracture and dissolution cavities will have different mechanical properties, and drilling through those features will require significantly less energy than through a competent rock formation. They are also discrete events within a geological formation, and therefore will have outlier mechanical properties within a formation.
The test was performed in over 300 wells, across different lost circulation zones (some wells had several zones). The developed algorithm was incorporated into the software in Real-time Monitoring center, allowing near real-time estimation of the aperture to decide regarding the LCM or LCP to be used. The results showed that in upper sections the multiple lost circulations zones presented with different thickness. The majority of the identified karsts are within range of 2-to-8 ft, with some going over 10 ft. In the deeper formations LCZ with the aperture of 4-to-9 ft were identified. The interesting part was related to the significant difference between MSE while drilling competent formation and the lost circulation zone, when MSE values were dropping almost to zero.
The manuscript provides the novel approach allowing to use machine learning to identify the aperture of the lost circulation based on the real time parameters. The proposed approach can be used at any drilling project worldwide.

Диспергирование сельскохозяйственного сырья представляет собой сложный технологический процесс. В большинстве случаев процессы измельчения достигли естественного предела скорости, и дальнейшее повышение эффективности их функционирования на существующей технологической платформе представляется трудноразре- шимой задачей. В связи с этим актуальны разработки новых концептуальных решений и методик, базирующихся на информационно-энергетических принципах. Разработана модель функционирования измельчителя дезинтеграторно- го типа, содержащего цилиндрический корпус, внутри которого расположены два вращающихся в противоположных направлениях ротора в виде дисков с ударными элементами. Представлена методика проведения поисковых экспери- ментов, позволяющая изучать преобразования в глубоких слоях веществ и микроэлементов. Предложенные схемотех- нические решения обеспечивают возможность управления качеством функционирования технологического процесса с учетом физико-механических, биологических и химических свойств исходного сырья. По разработанной методике получена обогащенная калием и фосфором порошкообразная кормовая добавка для сельскохозяйственных животных «Кедрослав» с дисперсностью 0,01–0,02 мм и относительным содержанием углеводов 68,4%. Результаты исследования в контрольной группе животных до и после проведения опытов свидетельствуют о положительном эффекте применения.
Dispersing agricultural raw materials is a complex technological process. In most cases, comminution processes have reached a natural speed limit, and further improving their efficiency on the existing technology platform appears to be a difficult task. In this regard, the development of new conceptual solutions and techniques based on information and energy principles is relevant. A model has been developed for the functioning of a disintegrator-type shredder containing a cylindrical body, inside of which there are two rotors rotating in opposite directions in the form of disks with impact elements. A methodology for conducting search experiments is presented that allows one to study transformations in deep layers of substances and microelements. The proposed circuit solutions provide the ability to control the quality of the technological process, taking into account the physical, mechanical, biological and chemical properties of the feedstock. Using the developed method, a powdered feed additive for farm animals «Kedroslav» enriched with potassium and phosphorus was obtained with a dispersion of 0,01–0,02 mm and a relative carbohydrate content of 68,4%. The results of the study in the control group of animals before and after the experiments indicate a positive effect of use.
Experience in testing content analysis in the study of the concept of «Russian idea»
Authors: Khamidulin A. M. , Babaeva A. V. 
Published: April 2024

Introduction. The article is devoted to the problem of the formulation of the substantive aspect of the Russian idea. The relevance of the text is determined by the fact that there is still no adequate understanding in the research literature of what should be included in the content of the concept. Moreover, the very existence of the Russian Idea is a problem area for the Russian philosophical tradition.Materials and Methods. The authors test an original approach to the study of the phenomenon, which consists in the application of quantitative tools to the study of the deep meanings of Russian civilization. The collection of material was carried out on the basis of 26 texts of the representatives of the national thought of different historical epochs and various ideological positions. The basic idea behind the research was the thesis that the Russian idea is a meta-narrative with a 1000-year history, in this regard, the hypothesis was put forward that none of the existing texts can be considered as exhaustive and fully reflecting the concept of the work. On this basis, the authors of the article analyzed all the source texts as separate chapters of a single narrative about the fate of Russian civilization and its role in the world historical process.Results. The data presented in the article were collected and processed using online resources: https://miratext.ru and https://istio.com/. The similarity of the algorithms of the resources, however, gave different results. As a result of automatic and manual viewing, the top 20 high-frequency and relevant words were formed for each of the sources, the categories were systematized and presented in a tabular version and a word cloud format. It was revealed that, although the analyzed texts are united by a single theme «Russian Idea», no single concept has been found that would be common to all the analyzed sources. The most frequent concepts should be noted as the following: «man», «Russian», «Russia», «life» and «people». These words, according to both programs, were in the top of the combined semantic core of all 26 sources. The study showed that these concepts are unifying for all the texts considered.Discussion and Conclusions. The presented results demonstrate the prospects of using quantitative methods that allow us to search for mathematical confirmation of the correctness of the semantic content of the Russian idea.
The anthropology of Islamic modernism – Jadidism
Authors: Evdokimov I. V. 
Published: April 2024

Introduction. This article is an attempt to study the anthropological views of Jadidism, one of the trends of Islamic modernist reformism aimed at bringing Muslim fundamental religious values closer to secular European culture. In an attempt to bring traditional Muslim anthropological categories closer to the European humanistic understanding of man, Jadid thought forms an updated Westernized version of Muslim anthropology.Materials and Methods. The material for the article was the researches of R. S. Khakimov, H. Bekiri, A. H. Basyrov, D. M. Iskhakov, M. Iqbal, M. Аbduh, G. Marranci, devoted to the analysis of anthropological concepts of Jadidism, formulating the basic principles of human perception by Islamic modernism. The article uses methods of systematic and comparative analysis, generalization and historical and philosophical analysis.Results. The conducted research shows that Jadidism develops the concepts of human freedom and personality, overcoming the determinism traditional for Islam, rethinks the anthropic principle in religious Muslim categories. The emphasis is placed on the personal beginning of a person, the center of his activity, due to the rational component and the presence of free will. Using these tools, a person communicates with the divine principle through the knowledge of the universe, synergistically applying the religious precepts of Islam in combination with the current scientific picture of the world. At the same time, the process of self-knowledge of a person as essentially refracting the divine nature in his nature is also important.Discussion and Conclusions. The author of the study managed to conduct a comparative, systematic and historical-philosophical analysis of the anthropological positions of Islamic modernist reformism – Jadidism – in the works of both domestic and foreign thinkers. As a result, the author managed to carry out a comprehensive analysis of the basic anthropological principles of Jadidism, as well as to trace the influence of various factors on the formation of the anthropology of Islamic modernism.
