Authors: Rosas Patiño Gelber , Avila Pedraza Edgar Alvaro , Sánchez Castillo Verenice
Published: February 2025

Contextualización: los suelos tropicales ácidos se caracterizan por presentar bajo pH, altas concentraciones de aluminio y baja disponibilidad de nutrientes, lo que limita el desarrollo de la raíz y la producción de los cultivos. Los suelos de la Amazonia colombiana, en donde predominan oxisoles y ultisoles, hacen parte de este grupo de suelos ácidos y de baja fertilidad natural.  
Vacío de conocimiento: el comportamiento de las plantas que crecen en suelos ácidos ha ocupado el interés de investigadores en todo el mundo, pero es escaza la información actualizada y de libre acceso que permita entender con suficiencia la naturaleza de estos suelos, así como las estrategias morfológicas, fisiológicas y bioquímicas de adaptación de los cultivos de importancia agrícola desarrollados en los suelos ácidos de la Amazonia colombiana.  
 Propósito: presentar una síntesis de los últimos avances científicos relacionados con los suelos ácidos, la relación de la acidez con la disponibilidad de nutrientes y los efectos tóxicos del aluminio, así como los mecanismos de adaptación desarrollados por las plantas. En esta revisión también se aborda de manera especial los efectos de la acidez del suelo en ocho cultivos de importancia agrícola para los productores en la Amazonia colombiana.  
 Metodología: se realizó una búsqueda de artículos de libre acceso publicados en cuatro bases de datos de la Web entre el 2020 y el 2023, sobre las formas del aluminio en el suelo, su relación con la disponibilidad de nutrientes, los efectos tóxicos, los mecanismos de tolerancia de la planta y algunas prácticas de manejo de suelos ácidos.  
 Resultados y conclusiones: este estudio aporta elementos importantes que ayudan a mejorar la comprensión de los suelos ácidos y plantea escenarios futuros para orientar la gestión del conocimiento, en relación con el manejo de los suelos ácidos y los cultivos agrícolas en la Amazonia colombiana.
Mental health of youth under the digital mediatization
Authors: Liadova A. V. , Zapletnuk M. A.
Published: February 2025

The article deals with the study of mental health of Russian youth in the context of digital mediatization. The authors note that, although this topic is widely represented in the scientifi c discourse, there is no consensus among researchers. An analysis of current approaches to studying the problem of the infl uence of new media on the mental health of the younger generation shows that there is a tendency to move from the concept of “demonization” to the search for positive aspects. Nevertheless, unambiguous assessments of this problem still seem limited. The paper proposes a diff erentiated approach consisting in the analysis of both vectors of the infl uence of digital mediatization on the mental health of young people, both positive and negative aspects. In this regard, the authors reviewed the results of an empirical study of the Russian segment of the blogosphere on mental health issues. Based on the data obtained, groups of blogs (the so-called “patient” and “mentoring”) were identifi ed, and the features of the discourse in them about mental health issues were studied. The paper also analyzes the main factors of mental health and proposes criteria for their classifi cation.
Digital transformation in the People’s Republic of China: dynamics and trends
Authors: Zuo Qi
Published: February 2025

The article is devoted to the current issues related to the digital transformation of the People’s Republic of China. It presents a systematic analysis of the most important aspects of digital transformation in this country from various points of view. Digital transformation is, fi rst of all, a process and means of implementing the digital economy, and China is one of the leaders in this fi eld. Data from the China Academy of Information and Communications Technology show that the scale of China’s digital economy is increasing year by year, and in 2022 it reached 50,2 trillion yuan (about 7,27 trillion dollars), which is 41,5% of China’s GDP. However, the level of development of China’s digital economy is still insuffi cient — although China’s digital economy is large-scale and leads the world, its share in the overall structure of economic activity in this country is not high. The digital economy includes digital industrialization and industrial digitalization, the features of which, supported by specifi c data, are analyzed in detail in the article.The author has proven that China’s digital transformation is uneven. There is a huge disparity in the penetration levels of the three main sectors of the economy. Digital transformation has the highest penetration rate in the service sector — 44,7%, followed by the industrial sector — 24,0% and the agricultural sector — 10,5%; coastal areas live better than inland areas, the southern ones are better than the northern ones. At present, China has basically completed the design and structure of building a digital government. However, there are many problems in the process of building a digital government, including the overlapping functions of digital and traditional government, changes in the original government structure, and the impact of new rules and systems on the current governance system, which are discussed in detail in the article.The advantages of China’s digital economy are concentrated in new digital industries such as e-commerce, digital fi nance, cloud computing, unmanned aerial vehicles, and the photovoltaic industry. China not only promotes digital transformation in these areas of economic activity, but also carries out deep digital transformation in public services such as medical care, education, and security. At the same time, the characteristics of digital transformation have caused social problems such as digital inequality, the lack of reliable digital governance systems, and structural unemployment, which are analyzed in detail in the article. One of the eff ective means to solve these problems is digital trust
Understanding the essence of the “Great Game” by classics of the Russian school of geopolitics (Ending)
Authors: Elishev S. O.
Published: February 2025

Th is article is devoted to understanding the essence of Th e Great Game — the policy of containing the development of Russia by Anglo-Saxon elites and powers, dating back more than two centuries, by the classics of the Russian school of geopolitics. Th e author of the article considers the geopolitical concepts of the founders of the civilizational approach and civilizational geopolitics — N.Ya. Danilevsky, K.N. Leontyev, representatives of pan-Slavism (R.A. Fadeev, I.I. Dusinsky), military-strategic direction (D.A. Milyutina, A.E. Vandama, A.E. Snesareva), Eurasia (P.E. N. Savitsky), Y.S. Kartsova, V.P. Semenova-Tyan-Shansky, P.N. Durnovo.Th e author emphasizes that the development of Russian geopolitical thought took place in the absence of a political order from the state, as well as political and economic elites to develop a geopolitical strategy for the development of Russia and the implementation of its foreign policy. Unfortunately, the author states, many ideas of the classics of the Russian school of geopolitics (in particular, in their understanding of the essence, content and dynamics of the Great Game) turned out to be unclaimed by the ruling circles and governments, among which there were many people, Anglophile orientation, promoting the ideas of allied relations with England, to the detriment of the national interests of Russia.At the same time, the author of the article notes, the understanding of the essence and features of the development of the events of the “Great Game” by representatives of the Russian school of geopolitics was largely carried out fragmentally, oft en in the aspect of analyzing the centuries-old civilizational confrontation between Russia and the Romano-German cultural and historical type (Western European great culture, civilization), and not purely continentalist concepts.Authors who comprehend the essence and signifi cant events of the “Great Game” in their works include: representatives of Pan-Slavism — N.Ya. Danilevsky, I.I. Dusinsky, R.A. Fadeeva; representatives of the military-strategic direction — A.E. Snesarev and A.E. Vandam; Y.S. Kartsov and P.N. Durnovo. Th e rest of the classics of the Rus sian school of geopolitics addressed this issue selectively, within the framework of other topics of interest to them

Published: February 2025

Introduction. Minor obstetric and gynecological operations are among the most frequently performed surgical interventions, including for emergency indications. At the present stage of anesthesiology, various anesthesia techniques are used, and there is no consensus regarding the optimal method of anesthesia for these operations. Purpose of the work: to determine the optimal method of anesthesia for minor obstetric and gynecological operations.

Objectives: 1. to study and analyze literature data on methods of anesthesia for minor obstetric and gynecological operations in outpatient practice and for emergency interventions in a 24-hour hospital. 2. Determine the optimal methods of anesthesia for this category of patients. 3. Identify factors influencing the choice of anesthesia method.

Material and methods. More than 20 literary sources have been studied, the main ones of which are presented in the list of references. A retrospective analysis of 2700 patients who underwent minor obstetric and gynecological operations at the Saint Petersburg I.I. Dzhanelidze Research Institute of Emergency Medicine and 400 patients of the Medsi clinic St. Petersburg.

Results. In our opinion, the optimal methods of general anesthesia are: usually non-inhalation or combined. The guarantee of effective and safe anesthetic care is preoperative preparation and selection of the optimal method of anesthesia in order to reduce the risks of negative effects, that is, a personalized approach is required. Propofol in combination with narcotic analgesics and combined anesthesia propofol-sevorane have proven to be the best in terms of controllability.

Conclusions. 1. The issue of pain relief during minor obstetric and gynecological operations is relevant and unresolved. 2. In our opinion, the optimal methods of general anesthesia are: non-inhalation propofol and narcotic analgesic and combined propofol and sevoran. 3. The choice of anesthesia method depends on many factors and should have a personalized approach.

The subject of the research is the factors determining the success of a career in information-oriented professions. The main focus is on analyzing the impact of professional experience, age, gender, level of education, as well as psychological variables (tolerance to uncertainty, job satisfaction, reflexivity, etc.). The purpose of the work is to identify the relationships between these factors and to determine the role of individual and organizational conditions in shaping career success. The research was based on : the theory of professional orientation of personality (N.E. Rubtsova), the theory of tolerance to uncertainty (S. Badner) and the model of development of reflexivity (A.V. Karpov), as well as the step model of professional growth (H. Dreyfus), systematization of the stages of professional development, developed by E.A. Klimov, Yu.P. Povarenkov and N.S. Pryazhnikov, analysis of the structural and functional aspects of information activities, presented by S.L. Lenkov and A.A. Karpov. The following methods were used: INL-2 (N. E. Rubtsova), JSS (Cammann, Fichman, Jenkins, & Klesh), IAS (T. V. Kornilova, M. A. Chumakova), measurement of reflexivity (A.V. Karpov), as well as empirical methods (questionnaires, correlation and comparative analyses). The results indicate that career success is determined by a combination of objective characteristics (experience, educational level) and subjective indicators (job satisfaction, tendency to reflection), employees with higher experience demonstrating strategic planning and professional maturity, while young professionals are flexible and satisfied with interpersonal interaction. The scope of the data obtained covers the field of human resource management and professional consulting. The identified relationships can be used to develop individual career support programs, increase adaptability to uncertainty, and effectively plan staff development in information-oriented organizations. The conclusions drawn emphasize the complex nature of career success, which requires taking into account both professional experience and educational level, as well as personal qualities and psychological readiness for change. The practical value of the conducted research lies in the possibility of optimizing HR strategies aimed at increasing motivation, building competencies and creating conditions for the long-term career development of specialists in information-oriented professions such as data analysts, web programmers, data architects, etc.
The implications of new censorship theory: Conformity and resistance of subtitle translators in China
Authors: Yan Lu
Published: February 2025

Censorship penetrates the decisions made about multilingual communication in an age defined by technification, digitisation and ‘Internetisation’. Rather than perceiving censorship solely as a repressive action externally exerted on subjects, this article explores its productive nature in the hands of new censorship theory in both official and non-official contexts. At its outset, the article presents the Chinese government’s legal control over the media landscape, casting a shadow over the subtitling industry’s present policies. It then examines three self-censorship practices of subtitle translators, based on in-depth interviews and questionnaires conducted with professional and non-professional subtitle translators in state media, media localisation companies and fan-subtitling teams. Subtitle translators, under the impact of explicit and implicit regulations imposed by state actors and structural mechanisms of control, either conform to or circumvent and challenge these regulations. Productive censorship can shape the knowledge and opinions, foster extensive discussions, inspire innovative translation strategies, create fresh lexicons, and enhance the marketability of audiovisual products to a wider audience.

Room Temperature Ruthenium-Catalyzed Coupling of Cyclopropanols and α-Diazo-β-Ketoesters to α-Ester-δ-Diketones
Authors: Fang Lili , Zhou Renpeng , Zhu Jin
Published: February 2025

Organic synthesis in the conventional descriptor wisdom of reactivity chemistry scheme asserts functional group as the originator of reactivity in reactive site, leading to ill-informed reaction development from a static, local perspective. We report herein the proposal of reactivity transduction chemistry scheme, a descriptor system highlighting reactivity and reactive fragment flow as the source for emergence of reactivity, showcasing a well-informed, dynamic, global perspective for reaction development. Through the lens of this descriptor system, the reactivity flow of zinc carbenoid and azide promises the differentiation of ineffective ketone–β-ketoester cross coupling reactivity into competent cyclopropanol–α-diazo carbene cross coupling reactivity. Correspondingly, a room temperature ruthenium catalytic protocol has been developed for the coupling of cyclopropanols and α-diazo-β-ketoesters to α-ester-δ-diketones, featuring a broad substrate scope. The two-carbonyl, one-ester molecular architecture in α-ester-δ-diketones presents an ideal combinatorial synthetic handle for further elaboration into a diversified pool of linear and cyclic structures. The ubiquity of reactivity flow in reaction chains promises reactivity transduction chemistry as a powerful conceptual tool for the productive establishment of most efficient global reactivity network.

Authors: Kaur Leela , Nehra Ajay Kumar
Published: February 2025

The current study aims to do rainfall analysis of Jhunjhunu district with reference to time and space for a period of 22 years by using quantum geographic information system (qGIS). The data collected were yearly rainfall and rainy days. These data were analysed in qGIS software. Inverse Distance Weighting (IDW) method of interpolation was adopted for the study. Thematic maps were generated. Rainfall maps displayed a growing tendency in rainfall amount while rainy days represented a slow increasing pattern. It was found that south, south-eastern and some part of north region of the Jhunjhunu get the utmost rainfall. However, north-eastern and western parts of the district receive the lowermost rainfall. It was observed that Khetri block received the highest rainfall during the average 20 years period. Though, Jhunjhunu block got the lowest rainfall during the whole period. Malsisar and Udaipurwati blocks got average rainfall. As ground water recharge rate is low in the study area, it is essential to collectively utilise surface water, available rainfall and groundwater for optimum irrigation and further agricultural management in the district. The rainfall analysis facilitated the understanding of the rainfall pattern which would be advantageous for strategic planning of efficient irrgiation and water availability in the study area.
AN ASSESSMENT AND PREDICTION OF SOIL EROSION RISK USING MODIFIED FOURNIER INDEX AND MACHINE LEARNING ALGORITHM: AN EXTERNAL AGRICULTURAL PROJECT RISK
Authors: Hlalele Bernard Moeketsi
Published: February 2025

Soil erosion, defined as a naturally occurring process that adversely affect all landform leads to increased pollution and sedimentation in rivers and streams which causes decline in fish and other forms of aquatic life. Suitable land use guided by scientific research findings can help reduce these impacts. The current study therefore aimed at characterisation and prediction of soil erosion by water using Modified Fournier Index methodology. Prior to final data analysis, data quality checks were deployed where outliers were detected, removed and replace by expectation maximum algorithm aided by SPSS. A machine learning algorithm, Neural Network was applied to forecast probable annual values of the Modified Fournier Index (Cp). Major findings exhibited a significant decreasing trend implying a high likelihood of drought events in the area. This phenomenon provides an insight for possible shift in the type of soil erosion risk to prevail in the near future, where soil particles will be prone to wind erosion. The Neural Network forecasted Fournier index values were seen diminishing annually. From these results it is therefore recommended that more studies be undertaken on drought risk analysis since Fournier index values are diminishing giving way to drought events. This information will provide details necessary for informed decision in the protection and sustainability of the Agricultural activities in the study area.
THE IMPACT OF HEAVY METAL CONTAMINATION ON AGRICULTURAL ECOSYSTEM: A REVIEW
Authors: Aji Zakka Mercy , Olufemi Aremu-Dele
Published: February 2025

Rapid industrialization over the past few decades has led to significant environmental pollution, with heavy metals being among the most hazardous contaminants due to their high toxicity and abundance. These metals, including Manganese, Magnesium, Copper, Iron, and Zinc are essential for plant growth in specific amounts but can be detrimental in excess, causing disruptions in photosynthesis and other physiological processes. Heavy metals like Cadmium and Lead are particularly harmful, affecting plant growth and enzymatic activities, leading to reduced crop yields. Soil ecosystems and plant growth are disrupted by heavy metal deposition, impacting the food supply and soil performance. This study aims to examine various types of heavy metals, their sources, significance in agriculture, mitigation activities, and recommendations for their control. Heavy metals are classified into essential and non-essential categories, both of which can be toxic at high concentrations. Sources of contamination include both natural processes and anthropogenic activities such as industrial processes, waste disposal, and the use of pesticides and fertilizers. The accumulation of heavy metals in soils affects soil microbial communities and enzyme activities, leading to soil degradation and reduced plant productivity. Understanding the sources, effects, and mitigation strategies for heavy metal contamination is crucial for sustainable agricultural practices and environmental health.

This research was motivated by many immoral cases that occurred in the pesantren environment. It is a terrible moral disaster in the world of education, where institutions oriented towards Islamic education should give birth to Islamic characters, but in reality, the bearers of education are the main actors in moral depravity. The purpose of this study is to thoroughly explore the ideal characteristics of an educator according to Syaikh Az-Zarnuji in the book Ta'limul Muta'allim and how the institution's strategy in shaping the professionalism of PAI teachers. The result of this study is that there are 6 characters that a teacher must have: 1) Knowledgeable 2) Mature personality (wara') 3) Charismatic 4) Mature 5) Generous 6) Merciful and patient. These six characters are very relevant to the aspects of education, especially PAI teachers who do not only prioritize knowledge. However, knowledge must be accompanied by the formation of learner character and interactive learning. Thus, the institution can take the main role in shaping the professionalism of PAI teachers so as to realize the true purpose of Islamic religious education.

Published: February 2025

This study investigates university students’ conceptual understanding and misconceptions about the kinetic molecular theory of gases (KMTG) in Kazakhstan. A sample of 223 students from two universities was assessed using the KMTG concept inventory. The sample consisted of 54.3% females and 45.7% males, with participants primarily in their first year of study (64.1%) and aged 17-18 (79.8%). The findings reveal significant misconceptions of molecular motion, gas pressure, entropy, and temperature changes in thermodynamic systems. For instance, 81.2% of students demonstrated incorrect conceptions about entropy, while 80.3% misunderstood temperature behavior during adiabatic processes. Statistically significant differences were observed in performance based on university affiliation and grade level, with Abai Kazakh National Pedagogical University students and first-year students outperforming second-year students. However, no significant gender-based differences were identified. This research points out the persistence of misconceptions in molecular and thermodynamic physics, indicating the need for localized and interactive instructional strategies. These findings contribute to the growing body of literature on physics education in Central Asia, providing recommendations for curriculum development and teacher training in the region.

Modifying core items created a construct wrongly identified as measuring problem gambling: Commentary: Prediction of problem gambling by demographics, gaming behavior and psychological correlates among gacha gamers: A cross-sectional online survey in Chinese young adults
Authors: Xiao Leon Y. , Ballou Nick , Eben Charlotte
Published: February 2025

Tang et al. (1) reported that so-called ‘problem gambling,’ as they defined it, is associated with monetary spending on video game mechanics that involve randomisation (e.g., gacha mechanics (2,3) and loot boxes (4)) amongst young Hong Kong players of games containing such mechanics. At face value, that assertion is not surprising as a consistent line of research has previously established that relationship in Western countries (5–7), which has been relied upon in policymaking (8,9). Research conducted subsequent to Tang et al. in Mainland China has also replicated the relationship (10).However, unfortunately, Tang et al. suffered from a fundamental flaw. That study did not, in fact, measure ‘problem gambling’ as traditionally defined because Tang et al. significantly modified the measurement scale. Instead, Tang et al. measured only ‘problematic participation in gacha mechanics’ and proved various relationships existed between that construct and other variables, which arguably is less meaningful (11,12). The development of that new scale lacked transparency and evidence of reliability and validity. It is unclear whether that new measure is related to ‘problem gambling’ and, if so, to what extent. In any case, it is not, and cannot be used as, a direct replacement without further validationTang et al. could not in fact have been able to report on any issues concerning ‘problem gambling’ because by definition, they did not measure ‘problem gambling.’ They should not have claimed to have been able to test or comment on any psychological relationships concerning ‘problem gambling.’ The current framing of that paper and its conclusions are misleading to readers whose attention are not specifically drawn to this highly significant measurement modification. This comment intends to correct that misimpression. Simply put, Tang et al. did not prove what its title suggested. That paper must be treated with due caution and considered for exclusion from meta-analyses.

Published: February 2025

Video games have become a market that has been expanded rapidly, however running the current games requires a computer or console of last generation, where the first has better graphics performance but demands hardware upgrades which lead to higher costs. This can be avoided with the implementation of cloud-based video games, where servers provide the power of the central and graphics processing mainly to applications with high requirements, allowing that any user with an internet connection can execute in any type of device, graphically-demanding games remotely without worrying about their hardware requirements. This paradigm is known as cloud gaming. In this paradigm there are several platforms and services, mostly private solutions, created to minimize latency experienced by the end user, but with little documentation of them. This article presents a survey about cloud gaming, in order to contribute to the documentation and show research fields of this technology.

This article presents a low cost prototype potentiostat, which allows to control electrical variables in obtaining coatings by electrodeposition. The QFD (Quality Function Deployment) methodology was used as a planning tool in order to determine the characteristics that should have the potentiostat along the entire process of obtaining the prototype. The development of the research was based on the design and implementation of a prototype potentiostat that can handle three basic functions of electrodeposition. One first function, chronoamperometry lets to keep a constant voltage in the range of 0 V to 20 V and measures the current delivered to the system. A second function, chronopotentiometry maintains constant a current in a range of 0 A to 2 A and measures the voltage (potential). A third function, cyclic voltammetry, works in the same ranges of chronoamperometry (0 V to 20 V) and excites the system by signals as triangular wave, saw tooth, sine, and square, among others. These implemented features were compared to one conventional potentiostat, demonstrating its efficiency in controlling electrochemical processes.

This work focused on characterizing by techniques TGA, DTG and IR, the coagulation of natural rubber latex, by using formic acid and acetic acid, samples classified as clone IAN-710 grown in Caquetá were used, in order to compare the use of these acids on different concentrations, and the impact they have on the thermal and chemical properties (volatile matter and ash). The characterization was carried out by differential scanning calorimetry, thermogravimetric analysis and infrared spectroscopic identification. It was observed that the variation of acids concentration does affect neither the thermal properties within a significant change, nor the major molecular chemical structure of rubber as poly (cis-1, 4 -isoprene).

Құрамында жоғары металл, шайырлы-асфальтен компоненттері мен гетероқосылыстарының мөлшері көп мұнай өндіру және оны өңдеу көлемі жыл артқан сайын өсуде. Мұнайды  вакуумдық немесе терең вакуумдық айдаудан түзілетін ауыр қалдықтарды қайта өңдеу өзекті мәселелердің бірі. Мұнайды қайта өңдеуді жетілдірудің әдісі - өте ауыр және сапасы нашар қалдықтарды қайта өңдеу болып табылады. Осы уақытқа дейін терең және ағынсыз қайта өңдеуге арналған технологиялар мұнай мен мұнай қалдықтарында тек металдардың ғана емес, катализаторлардың улануына әсер ететін күкірт мөлшерлерінің жоғары болуымен сипатталды. Құрамында 1,5 мас.% - дан  кем күкіртті кокс ең құнды болып табылады. Мұнай коксын өндіруші мұнай өңдеу зауыттары құрамында күкірті көп коксты төмен бағамен нарыққа шығарады. Бұл құрамында 2% - дан көп күкірті бар кокстың электродтық болуына және алюминий саласы үшін жарамсыз болуына байланысты. Құрамында күкірт көп коксты отын ретінде жағу экологияға зиян келтіреді. Осыған байланысты құрамында металл мен күкірті бар қосылыстарды алып тастау арқылы ауыр мұнай қалдықтарын өңдеудің жаңа технологияларын жасау мұнай өнеркәсібінің өзекті ғылыми мәселесі болып табылады. Қазақстан Республикасында күкірт пен металдың мөлшері бір пайыздан аспайтын мұнай коксы өндірілмейді. Ал, инеқұрылымды кокске қажеттілік жыл сайын артып келеді. Қазіргі таңда химия және мұнай-химия кешенін дамытудың стратегиялық мақсаттарының бірі мұнай өңдеу тереңдігін арттыру арқылы экспорттық-шикізаттық даму моделінен инновациялық-инвестициялық модельге көшу болып табылады. Мұнайды қайта өңдеу тереңдігін арттыруды қайта өңдеу процестерінің, атап айтқанда, ауыр мұнай қалдықтарын өңдеудің қуаттылығын арттыру арқылы қол жеткізуге болады.

Published: February 2025

El Servicio Geológico Colombiano presenta los tensores de momento sísmico y mecanismos focales calculados para sismos localizados en el territorio nacional y regiones fronterizas desde 2014 hasta 2021. Estas soluciones se obtuvieron usando diferentes métodos basados en inversión de formas de onda (SWIFT, SCMTV, Fase W e ISOLA) y polaridades de primeros arribos (FPFIT). Esta información se ha organizado en una base de datos y se ha dispuesto al público mediante una página web por medio de la cual se pueden hacer búsquedas por fechas, área circular o cuadrante. Las soluciones del centroide del tensor de momento son fundamentales para comprender la geometría de la falla, la fuente sísmica que produce un sismo, su magnitud, y la energía liberada por el mismo. Igualmente, gracias a esta información es posible hacer interpretaciones sobre la tectónica de placas, análisis de esfuerzos de la corteza terrestre y su dinámica, modelos dinámicos y cinemáticos de la fuente, análisis de fallas activas y potencial tsunamigénico de sismos, entre otros aspectos.
