First Report on Coseismic Ionospheric Disturbances Following the Deep-Focus Earthquake (Mw 6.6) in Tarauacá, Acre, Brazil: Ground Uplift and TEC Analysis
Authors: Adebayo Oluwasegun M. , Kherani Esfhan A. , Pimenta Alexandre A.
Published: September 2024

Abstract. On January 20, 2024, a deep-focus earthquake of magnitude 6.6 struck near Tarauacá, Brazil, at a depth of 607.0 km. While no surface damage was reported, this event marked a significant seismic occurrence in a region known for deep earthquakes associated with the subducted Nazca Plate. Using Global Navigation Satellite System (GNSS) Total Electron Content (TEC) data from the Brazilian Network for Continuous Monitoring of GNSS Systems (RBMC) and seismic data from the IRIS network, we analyzed the earthquake's impact on both ground surface (in form of uplift) and ionosphere (in form of disturbances). The results show clear ionoquakes characterized by distinct "N-type" wave patterns in TEC data, originating from infrasonic-acoustic waves launched from the earthquake's crustal displacement. The ionoquakes arrived in the ionosphere 8.3 minutes from the mainshock onset and traveled with the net propagation speed of 550 m/s to 743 m/s. This is the first report on coseismic ionospheric disturbances, or ionoquakes, following an earthquake in the Brazilian sector. The spectral analysis shows a maximum TEC amplitude in the frequency range 14 mHz – 16 mHz which suggest that the ionoquakes are signatures of high-frequency infrasonic-acoustic waves dynamics.
Mechanisms of soil organic carbon and nitrogen stabilization in mineral-associated organic matter – insights from modeling in phase space
Authors: Manzoni Stefano , Cotrufo M. Francesca
Published: September 2024

Abstract. Understanding the mechanisms of plant-derived carbon (C) and nitrogen (N) transformation and stabilization in soil is fundamental for predicting soil capacity to mitigate climate change and support other soil functions. The decomposition of plant residues and particulate organic matter (POM) contributes to the formation of mineral-associated (on average more stable) organic matter (MAOM) in soil. MAOM is formed from the binding of dissolved organic matter (ex vivo pathway) or microbial necromass and bioproducts (in vivo pathway) to minerals and metal colloids. Which of these two soil organic matter (SOM) stabilization pathways is more important and under which conditions remains an open question. To address this question, we propose a novel diagnostic model to describe C and N dynamics in MAOM as a function of the dynamics of residues and POM decomposition. Focusing on relations among soil compartments (i.e., modeling in phase space) rather than time trajectories allows isolating the fundamental processes underlying stabilization. Using this diagnostic model in combination with a database of 36 studies in which residue C and N were tracked into POM and MAOM, we found that MAOM is predominantly fueled by necromass produced by microbes decomposing residues and POM. The relevance of this in vivo pathway is higher in clayey soils but lower in C-rich soils and with N-poor added residues. Overall, our novel modeling in phase space proved to be a sound diagnostic tool for the mechanistic investigation of soil C dynamics and supported the current understanding of the critical role of both microbial transformation and mineral capacity for the stabilization of C in mineral soils.
Revisiting the high tropospheric ozone over Southern Africa: overestimated biomass burning and underestimated anthropogenic emissions

Published: September 2024

Abstract. Tropospheric ozone over Southern Africa is particularly high and causes tremendous health risks and crop yield losses. It has been previously attributed to the influence by biomass burning (BB), with a minor contribution from anthropogenic emissions. However, due to the lack of measurements for ozone and its precursors, the modeled impacts of BB and anthropogenic emissions on tropospheric ozone were not well evaluated in Southern Africa. In this study, we combined the nested GEOS-Chem simulation with a horizontal resolution of 0.5° × 0.625° with rare multiple observations at the surface and from space to quantify tropospheric ozone and its main drivers in Southern Africa. Firstly, BB emissions from current different inventories exhibit similar peaks in summer season but also have large uncertainties in Southern Africa (e.g., uncertainty of a factor of 2–3 in emitted NOx). The model-satellite comparison in fire season (July–August) in 2019 shows that using the widely used GFED4.1 inventory, the model tends to overestimate by 87 % compared to OMI NO2, while the QFED2 inventory can greatly reduce this model bias to only 34 %. Consequently, the modeled tropospheric column ozone (TCO) bias was reduced from 14 % by GFED4.1 to 2.3 % by QFED2; the simulated surface MDA8 ozone was decreased from 74 ppb by GFED4.1 to only 56 ppb by QFED2. This suggests a highly overestimated role of BB emissions in surface ozone if GFED4.1 inventory is adopted. The model-observation comparison at the surface shows that the global CEDSv2 anthropogenic inventory tends to underestimate anthropogenic NOx emissions in typical Southern African cities by a factor of 2–10 and even misrepresented anthropogenic sources in some areas. That means that urban ozone and PM2.5 concentrations in Southern Africa may be strongly underestimated. For example, a ten-fold increase in anthropogenic NOx emissions can change ozone chemistry regime and increase PM2.5 by up to 50 µg m−3 at the Luanda city. Furthermore, we also find that the newly TROPOMI can already capture the urban NO2 column hotspots over low-emission regions like Southern Africa while this is unavailable from the OMI instrument, highlighting the critical role of high-quality measurements in understanding atmospheric chemistry issues over Southern Africa. Our study presents a quantitative understanding of the key emission sources and their impacts over Southern Africa that will be helpful not only to formulate targeted pollution controls, but also to enhance the capability in predicting future air quality and climate change, which would be beneficial for achieving a healthy, climate-friendly, and resilient development in Africa.
Impact Webs: A novel conceptual modelling approach for characterising and assessing complex risks

Published: September 2024

Abstract. Identifying, characterising and assessing the complex nature of risks is vital to realise the expected outcome of the Sendai Framework for Disaster Risk Reduction. Over the past two decades, the conceptualization of risk has evolved from a hazard-centric perspective to one that integrates dynamic interactions between hazards, exposure, systems vulnerabilities and response risks. This calls for a need to develop tools and methodologies that can account for such complexity in risk assessments. However, existing risk assessment approaches are hitting limits to tackle such complexity. To this aim, we developed a novel complex risk assessment methodology named ‘Impact Webs’, inspired by a conceptual risk modelling approach named Climate Impact Chains that integrates aspects of various other conceptual models used in risk assessments such as Causal Loop Diagrams and Fuzzy Cognitive Mapping. Impact Webs are developed in a participatory manner with stakeholders and characterise and map interconnections between risks, their underlying hazards, risk drivers, root causes, responses to risks, as well as direct and cascading impacts across multiple systems and at various scales. In this methodological paper, we show how we developed the Impact Web methodology, including which elements we use to populate the model and steps we followed for construction. As proof of concept, we present the results of a complex risk assessments in Guayaquil, Ecuador, which investigated how COVID-19, concurrent hazards and responses propagate risks and impacts across sectors and systems during the pandemic. Reflecting on the utility of Impact Webs, application in case studies demonstrates the methodologies usefulness for understanding complex cause-effect relationships and informing decision-making across different scales. The participatory process of developing Impact Webs promotes stakeholder engagement, uncovers critical elements at risk and trade-offs in decision making, helping to evaluate both positive and negative outcomes of disaster risk management practices.
PDO-driven interdecadal variability of snowfall over the Karakoram and Western Himalaya
Authors: Bharati Priya , Deb Pranab , Hunt Kieran M. R.
Published: September 2024

Abstract. Our study reveals that the negative phase of the Pacific Decadal Oscillation (PDO−) leads to increased winter (DJF) snowfall in the Karakoram and Western Himalayas (KH) from 1940 to 2022. Interdecadal variations in DJF snowfall during the PDO− are attributed to deep convection and adiabatic cooling near the tropopause in both the northwest Pacific and KH region. Additionally, a wave-like pattern characterized by a trough (anomalous cyclone) north of KH and a ridge (anomalous Tibetan Plateau anticyclone) east of KH in the upper atmosphere, along the northward shift of the DJF Subtropical Jet (STJ) was observed. A strong positive correlation between DJF STJ strength and DJF snowfall in KH as well as a significant negative correlation between DJF STJ strength and DJF PDO, suggests a wave response over KH to the direct forcing over the northwest Pacific Ocean. The intensified STJ across KH results in higher frequency of Western disturbances, leading to anomalous moisture convergence and increased DJF precipitation in the region during the PDO−. These findings hold significant implications for the decadal predictability of winter snowfall in KH by the various phases of PDO.

Abstract. The Community Multiscale Air Quality Model (CMAQ) is a local- to hemispheric-scale numerical air quality modeling system developed by the U.S. Environmental Protection Agency (USEPA) and supported by the Community Modeling and Analysis System (CMAS) center. CMAQ is used for regulatory purposes by the USEPA program offices and state and local air agencies and is also widely used by the broader global research community to simulate and understand complex air quality processes and for computational environmental fate and transport and climate and health impact studies. Leveraging state-of-the-science cloud computing resources for high-performance computing (HPC) applications, CMAQ is now available as a fully tested, publicly available technology stack (HPC cluster and software stack) for two major cloud service providers (CSPs). Specifically, CMAQ configurations and supporting materials have been developed for use on their HPC clusters, including extensive online documentation, tutorials and guidelines to scale and optimize air quality simulations using their services. These resources allow modelers to rapidly bring together CMAQ, cloud-hosted datasets, and visualization and evaluation tools on ephemeral clusters that can be deployed quickly and reliably worldwide. Described here are considerations in CMAQ version 5.3.3 cloud use and the supported resources for each CSP, presented through a benchmark application suite that was developed as an example of a typical simulation for testing and verifying components of the modeling system. The outcomes of this effort are to provide findings from performing CMAQ simulations on the cloud using popular vendor-provided resources, to enable the user community to adapt this for their own needs, and to identify specific areas of potential optimization with respect to storage and compute architectures.
Atmospheric-river-induced precipitation in California as simulated by the regionally refined Simple Convective Resolving E3SM Atmosphere Model (SCREAM) Version 0
Authors: Bogenschutz Peter A. , Zhang Jishi , Tang Qi , Cameron-Smith Philip
Published: September 2024

Abstract. Using the regionally refined mesh (RRM) configuration of the US Department of Energy's Simple Cloud-Resolving Energy Exascale Earth System Model (E3SM) Atmosphere Model (SCREAM), we simulate and evaluate four meteorologically distinct atmospheric river events over California. We test five different RRM configurations, each differing in terms of the areal extent of the refined mesh and the resolution (ranging from 800 m to 3.25 km). We find that SCREAM RRM generally has a good representation of the AR-generated precipitation in CA, even for the control simulation which has a very small 3 km refined patch, and is able to capture the fine-scale regional distributions that are controlled largely by the fine-scale topography of the state. It is found that SCREAM generally has a wet bias over topography, most prominently over the Sierra Nevada mountain range, with a corresponding dry bias on the lee side. We find that refining the resolution beyond 3 km (specifically 1.6 km and 800 m) has virtually no benefit towards reducing systematic precipitation biases but that improvements can be found when increasing the areal extent of the upstream refined mesh. However, these improvements are relatively modest and only realized if the size of the refined mesh is expanded to the scale where employing RRM no longer achieves the substantial cost benefit it was intended for.
Derivation of Moisture-Driven Landslide Thresholds for Northeastern Regions of the Indian Himalayas
Authors: Monga Danish , Ganguli Poulomi
Published: September 2024

Abstract. Landslides pose a significant threat in the Northeastern Himalayas, driven by monsoonal rains and exacerbated by rapid urbanization. This research establishes moisture (primarily rainfall) thresholds that can cause landslides in Northeastern Himalayas 'hotspots' based on 490 rain-driven landslides catalogued between 2006 and 2019. Coupling the innovative Regularized Expectation-Maximization approach with non-crossing quantile regression, we reveal critical insights into antecedent moisture conditions and their role in shallow to deep landslide genesis. Our derived moisture threshold for the Northeastern Himalayan region, E (mm) = −11.10 + 0.62 D (hour), for 24 < D < 1440 hr, fits within global bounds for both deep and shallow landslides. The spatial analysis demonstrates significant heterogeneity, with Guwahati (located at 26.14° N, 91.74° E in Assam) and Shillong (located at 25.58° N, 91.89° E in Meghalaya) requiring higher cumulative rainfall for landslide triggers compared to Aizwal (located at 23.73° N, 92.72° E in Mizoram). Our analysis shows that environmental controls, e.g., elevation, slope, land use types, CND, and rock types, play significant roles in shaping rainfall thresholds to trigger landslides. The insights from this research offer effective landslide risk management strategies and advance the predictive capabilities of Landslide Early Warning Systems with broader implications for climate resilience and disaster preparedness.
Representation learning with unconditional denoising diffusion models for dynamical systems
Authors: Finn Tobias Sebastian , Disson Lucas , Farchi Alban , Bocquet Marc , Durand Charlotte
Published: September 2024

Abstract. We propose denoising diffusion models for data-driven representation learning of dynamical systems. In this type of generative deep learning, a neural network is trained to denoise and reverse a diffusion process, where Gaussian noise is added to states from the attractor of a dynamical system. Iteratively applied, the neural network can then map samples from isotropic Gaussian noise to the state distribution. We showcase the potential of such neural networks in proof-of-concept experiments with the Lorenz 1963 system. Trained for state generation, the neural network can produce samples that are almost indistinguishable from those on the attractor. The model has thereby learned an internal representation of the system, applicable for different tasks other than state generation. As a first task, we fine-tune the pre-trained neural network for surrogate modelling by retraining its last layer and keeping the remaining network as a fixed feature extractor. In these low-dimensional settings, such fine-tuned models perform similarly to deep neural networks trained from scratch. As a second task, we apply the pre-trained model to generate an ensemble out of a deterministic run. Diffusing the run, and then iteratively applying the neural network, conditions the state generation, which allows us to sample from the attractor in the run's neighbouring region. To control the resulting ensemble spread and Gaussianity, we tune the diffusion time and, thus, the sampled portion of the attractor. While easier to tune, this proposed ensemble sampler can outperform tuned static covariances in ensemble optimal interpolation. Therefore, these two applications show that denoising diffusion models are a promising way towards representation learning for dynamical systems.
An Introduction to Operational Chains in Ocean Forecasting
Authors: Wan Liying , Garcia Sotillo Marcos , Bell Mike , Drillet Yann , Aznar Roland , Ciliberti Stefania
Published: September 2024

Abstract. Operating the ocean value chain requires implementation of steps that must work systematically and automatically to generate ocean predictions and delivers ocean data information in standard format. This task, that represent the backbone of operational forecasting systems, implies the design of robust workflows, that organize pre-processing of the upstream data, run of the core models and post-processing before the final delivery. Operational chains require dedicated computational resources to supply demanding modelling runs but also processing and analysis of big volume of data, in relation to the specific spatial scale and consistently for the forecast lead times. The monitoring of each step of the workflow through key performance metrics can support not only the timely delivery but also identifying problems and troubleshooting. The paper illustrates the main challenges foreseen by operational chains in integrating complex numerical frameworks from global to coastal scale and discusses on existing tools that facilitate orchestration of operational chain components, including examples of existing systems and their consolidated capacity in providing high quality and timely ocean forecasts.
Multiscale modeling of heat and mass transfer in dry snow: influence of the condensation coefficient and comparison with experiments
Authors: Bouvet Lisa , Calonne Neige , Flin Frédéric , Geindreau Christian
Published: September 2024

Abstract. Temperature gradient metamorphism in dry snow is driven by heat and water vapor transfer through snow, which includes conduction/diffusion processes in both air and ice phases, as well as sublimation and deposition at the ice–air interface. The latter processes are driven by the condensation coefficient α, a poorly constrained parameter in the literature. In the present paper, we use an upscaling method to derive heat and mass transfer models at the snow layer scale for values of α in the range 10−10 to 1. A transition α value arises, of the order of 10−4, for typical snow microstructures (characteristic length ∼ 0.5 mm), such that the vapor transport is limited by sublimation–deposition below that value and by diffusion above it. Accordingly, different macroscopic models with specific domains of validity with respect to α values are derived. A comprehensive evaluation of the models is presented by comparison with three experimental datasets, as well as with pore-scale simulations using a simplified microstructure. The models reproduce the two main features of the experiments: the non-linear temperature profiles, with enhanced values in the center of the snow layer, and the mass transfer, with an abrupt basal mass loss. However, both features are underestimated overall by the models when compared to the experimental data. We investigate possible causes of these discrepancies and suggest potential improvements for the modeling of heat and mass transport in dry snow.

STATE SUPPORT FOR THE RUSSIAN INFORMATION AND COMMUNICATION TECHNOLOGY SECTOR IN THE CONTEXT OF EXTERNAL RESTRICTIONS
Authors: Sokolov A.B.
Published: September 2024

A necessary condition for Russia to achieve technological sovereignty is the strengthening of the national sector of information and communication technologies, which ensures digital transformation of the economy, social sphere, state and corporate governance. The state plays a key role in supporting the development of this sector. Supportive and stimulating measures adopted by the Russian government after an unprecedented increase in sanctions pressure on the country ensured a generally positive development of the sector in 2022-2024. At the same time, their prolongation and improvement, especially in the area of investment support for implemented and planned projects, is an urgent task, the solution of which requires scientific substantiation.
Desafios e Avanços do Proeja: Uma Análise de 2016 a 2023

Published: September 2024

O Programa Nacional de Integração da Educação Profissional com a Educação Básica na Modalidade Educação de Jovens e Adultos (Proeja) foi criado, em 2005, pelo decreto presidencial 5.478/24.06.05 e revogado pelo 5.840/13.07.06. Estabeleceu-se ali (§1o, Art. 2o) que as instituições federais de educação profissional deveriam implantar cursos e programas regulares do Proeja até 2007. No contexto desses preceitos, a Lei 11.892/2008, que instituiu a Rede Federal de Educação Profissional, Ciência e Tecnologia (RFEPCT) e criou os Institutos Federais de Educação, Ciência e Tecnologia (IF), estabeleceu como um dos objetivos destes (Seção III, Art. 7o, inciso I) ministrar educação profissional técnica de nível médio, prioritariamente, na forma de cursos integrados, tanto para os concluintes do ensino fundamental, quanto para o público da Educação de Jovens e Adultos (EJA). Como a pesquisa educacional publicada a partir de 2016, quando decorreu a primeira década dessa legislação, avalia o processo de implantação e implementação dessa política pública? Para responder a essa pergunta, buscamos pelo termo “Proeja” nas bases Scientific Electronic Library Online (Scielo), Sistema de Información Científica Redalyc, Revista Cadernos da Educação Básica e  na Revista Cadernos Cajuína, usando como filtros artigos em língua portuguesa e espanhola, no período 2016-2023. Ao todo, encontramos 155 textos (5 na Scielo, 1 na Revista Cadernos da Educação Básica, 2 na Cadernos Cajuína e 147 na Redalyc, que repetiu os achados da outra base). Lidos os títulos e resumos, retiramos 135 textos do corpus investigativo, pois não apresentavam o escopo de nosso interesse temático. Analisados os 20 textos restantes, percebemos ser consenso nessa literatura que o Proeja segue incompreendido na Rede Federal de Educação Profissional e Tecnológica, bem como a consolidação da RFEPCT como instituição de qualidade acadêmica e profissional, cuja cultura institucional vincula-se às possibilidades formativas (“de alto nível”) que ela indica, tem, possivelmente, gerado os fundamentos das resistências em torno da assunção orgânica do Programa.

The greatest tragedy for the Ukrainian Orthodox Church and the Ukrainian Greek Catholic Church occurred under the totalitarian Stalinist regime. Using the nineteenth-century proven scenarios of the tsarist autocratic Orthodox authorities' massacres of Uniates and Roman Catholics, the Soviet authorities used this historical experience to abolish the Union of Brest, sever the Ukrainian Greek Catholic Church's ties with the Vatican, and “reunite the Uniates” (Greek Catholics), as they said in Moscow at the time, “with their mother, the Russian Orthodox Church” (1946).

The purpose of the article is to publish fragments of a biographical dictionary - biographies of priests with the letter "A". Research methodology: biographical and prosopographical methods are outlined as the main ones in the process of implementing this project. The scientific novelty is that the publication of the second part of the series of biographies (biographical notes) of representatives of the clergy of the Stanislaviv Diocese under the letter "A" has been carried out. This publication includes the biographies of such persons as Andriishyn Mykhailo (1876–1938) and Andriishyn Yakiv (1845–1918). Conclusions: The reconstruction of the biographies of Greek Catholic priests (on the letter "A"), based on a significant source base, proves their active activity not only in the church and religious, but also in the political, public, economic and cultural spheres of the life of the Ukrainian people.
Military occupations conducted by Russia in the 21st century and their implications: the cases of Georgia and Ukraine
Authors:   International Black Sea University, Chitadze Nika
Published: September 2024

For centuries, Russia has been a country that has demonstrated its strength in the international political system. First, the emergence of the Soviet Union and 15 countries united under one roof, and then its collapse in 1991, made Russia a more aggressive state, as the international community witnessed during these years. This was mainly directed against the post-Soviet space, as Russia still believes that post-Soviet countries are and should be under Russian influence. This is the main reason why Russia has an aggressive foreign policy towards its neighbors, especially Georgia and Ukraine. The wars against Ukraine and Georgia show how great the threat from an imperialist neighboring state can be. The three main years of the wars are outlined here: 2008, 2014, and 2022, when Russia began a new military occupation of Ukraine. This aggressive foreign policy dimension poses a threat not only to the post-Soviet space, but also to international security. Russia's domestic and foreign policy has always been a subject of the international world order, as its steps have always had certain consequences for both the regional and international political system. In this study, we will look at the main consequences of the military occupations carried out by Russia in the 21st century.
Factors affecting rural youth participation in the smallholder farming sector
Authors: Mukwedeya Bright , Mudhara Maxwell
Published: September 2024

Youth participation in agriculture across Africa remains notably low, failing to reflect significant investments made in the sector. Much of the discussion to date on factors affecting rural youth participation in agriculture has occurred in the absence of robust and compelling evidence. As a result, most policy decisions rely on misconcep­tions about youth intentions and involvement in agriculture, leading to ineffective strategies for increasing their participation. This study aims to examine the factors influencing rural youth partici­pation in agriculture, particularly in the context of smallholder farming. A pre-tested, structured ques­tionnaire collected data from 200 youths (aged 15 to 35 years) across three districts of Mashonaland East Province in Zimbabwe. Both inferential and descriptive statistics were employed to analyze the data. The findings indicate that the future of agri­culture and food security in the study areas is uncertain, with more than 70% of the youth surveyed indicating they do not anticipate engaging in agriculture during the next five years. The factors associated with youth participation in agriculture were found to be multifaceted, encompassing demographic, economic, psychological, educa­tional, and technological dimensions. To enhance youth involvement in agriculture, the study recom­mends a shift from the traditional siloed approach to an interdisciplinary strategy that includes com­prehensive planning, investment, and decision-making.
IMPROVING THE PARAMETERS OF A LINEAR INDUCTION MOTOR WITH A MASSIVE SECONDARY ELEMENT
Authors: Mayilyan A.L. , Saghatelyan M.A. , Khangeldyan A.G.
Published: September 2024

A method for improving the parameters of linear asynchronous motors with a massive secondary element, which differ from normal induction motors in the design, size and shape of the main parameters and characteristics is proposed. Linear induction motors are widely used in actuators of industry and production that require linear movement. Linear asynchronous motors with a massive secondary element, where an alloy of iron and copper is used as the material of the secondary element, have been studied. Different percentages of metals in the iron and copper alloy are considered, which makes it possible to change the electrical resistivity ρ and magnetic permeability μ within specified limits. In the process of propagation of electromagnetic energy in a ferromagnetic environment, the change in the magnetic permeability of the environment as the wave moves through space is significant, which is associated with a change in the amplitude of the field strength. Magnetic permeability increases in relatively weak fields and decreases in sufficiently strong fields. The main electromechanical parameters of the system of a two-way linear induction motor with a massive secondary element made of an iron and copper alloy are calculated. The nominal values of the power factor and efficiency of a linear induction motor are obtained for different percentages of metals in the iron and copper alloy. The dependences of the power factor and efficiency on slip are given, and the values of the traction force of a linear induction motor with a massive secondary element made of an iron and copper alloy with different percentages of metals in the alloy are obtained.
ON THE SUPPRESSION OF VIBRATIONS IN ELASTIC LINKS OF A THREEMASS ELECTRIC DRIVE SYSTEM
Authors: Baghdasaryan M.K. , Davtyan D.V. , Alavedyan S.S.
Published: September 2024

The main reason for failures of technological mechanisms is associated with the failure of elements of the electric drive system. One of the main reasons for the malfunction of electric drive elements is the presence of vibrations in the elastic links of the mechanical part of the electric drive. Such phenomena mainly occur during transient processes of starting and stopping an electric drive, as well as under the influence of a load that is variable in nature. From the above, it is obvious that suppression of vibrations in the elastic links of the mechanical part is of practical interest. The most promising studies aimed at studying and suppressing vibrations in the elastic links of a three-mass electric drive system are analyzed. A comparative analysis of these studies shows that they consider the operating features of individual specific electric drive systems, which cannot provide a complete understanding of a comprehensive solution to the problem of ensuring the suppression of vibrations, arising in the mechanical part for various reasons. That is why it is necessary to evaluate the possibilities of suppressing elastic vibrations of the electric drive system, taking into account all its links. The goal of this work is to propose an approach for suppressing vibrations in the elastic links of a three-mass electric drive system.
The change in the elastic moment under various characteristics of the load created by the mechanism is considered, in particular, in cases of constant moment, exponential and step laws of change. The capabilities of proportional-integral (PI) and proportional-integral-derivative (PID) controllers for suppressing oscillations are analyzed. It is substantiated that although the system stabilizes with a PID controller in a short time, it does not provide the expected result and therefore it is recommended to use a controller with a fuzzy logic due to its simple control and rather high efficiency. The results obtained can be successfully used to improve the reliability of a three-mass electric drive system.
تأثیر گفتمان‌های ایدئولوژیک مرکز در بیگانه‌ ساختن کردها با هویت ایرانی
Authors: Kurde Chalak
Published: September 2024

ظهور مدرنیته و برخورد دول خاورمیانه با آن باعث بازخوانیِ نوین و تغییر در هویت افراد و گروه‌های قومی و مذهبی شد، بطوری که ملت‌ها بدنبال تعمیق تفاوت‌های فرهنگی، ملی و زبانی برآمدند. برخورد ایران با مدرنیته در انقلاب مشروطه که آن را می‌توان نقطه آغاز گفتمان‌های مدرن در ایران دانست، باعث شکل‌گیری هویت ملی در کنار هویت دینی شد. شیفتگی تجدد در بین روشنفکران ایرانی که مشروطه توان تحقق آن را نداشت، منجر به کنار گذاشتن آرمان‌های مشروطه که اکثر ملت‌های ایرانی به آن تعلق خاطر داشتند و ظهور دیکتاتوری منور در راستای پیاده‌کردن تجدد حتی به زور شد. دیکتاتوری شکل‌گرفته با کمک روشنفکران و با توسل به ایدئولوژی ناسیونالیسم ایرانی در راستای حذف و انکار هویت و زبان دیگری‌ها از جمله کردها، با استفاده از آموزش‌ و سرکوب قدم برداشت. این انکار بعد از انقلاب ۵۷ در چهارچوب ایدئولوژی ملی مذهبی نیز تداوم پیدا کرد و کردها اینبار، هم به دلیل مذهب متفاوت، هم به دلیل ملتی متفاوت به حاشیه رانده شدند. در این پژوهش بدنبال آن هستیم که بررسی کنیم سیاست‌ها و گفتمان‌های حاکمیت و روشنفکران مرکز و انکار سوژگی کردها از طرف مرکزگرایان تا چه اندازه در بیگانگی کردها با هویت ایرانی موثر بوده است؟ و باعث شد که کوردها بدنبال خوانش و هویت متفاوت از مرکز برآیند تا سوژگی و عاملیت خود را بازیابند. همچین بررسی خواهم کرد عدم تقسیم عادلانه امکانات اقتصادی، آموزشی، فرهنگی و ورزشی در صد ساله گذشه چه در دولت‌های پهلوی اول و دوم و چه بعد از انقلاب ۵۷ و عدم مشارکت کردها در سیاستگذاری و اداره دولت و حتی شهرهای خود، چگونه این دو قطبی‌شدن مرکز و پیرامون را تشدید کرده و کردها را به این اقناع نزدیک کرده است که در ایران از جایگاه شهروندی برخوردار نیستند و برای تحقق حقوق اولیه و برخورداری از امکانات و حفظ هویت خود، راهی بجز رهایی از مرکز را نمی‌توانند متصور شوند.

Published: September 2024

In this paper we will present a new adaptive control technique based on type 1 fuzzy controllers to control the mechanical power generated by a permanent magnet synchronous motor, this machine is powered by two converters in series. One converter on the network side to control the direct current bus and improve the power factor on the network side, the other on the motor side to regulate the mechanical power (speed, torque) produced by our motor. We will then present a comparative study between the developed controller and other conventional controllers to highlight the best performing and most robust of each, this comparative study is based on a series of tests that we have carried out during the transient and continuous operation of our permanent magnet synchronous motor under the same conditions. The numerical simulations demonstrate the effectiveness of the implementation of the typical adaptive type 1 fuzzy control to achieve these objectives.

Cleft lip/palate is a congenital maxillofacial malformation which results from genetic and environmental factors. In Brazil, the prevalence is 1 in every 673 live births. Several alterations result from oral clefts and affects function, aesthetics, and social life. Due to morphofunctional changes, these patients are more susceptible to disorders of the oral cavity. This study aimed to conduct an epidemiological study about alterations of the stomatognathic complex in cleft lip/palate patients at Albert Sabin Pediatric Hospital in Fortaleza, Ceará, Brazil. Files containing medical records, imaging exams and dental models of 64 patients from 2005 to 2017 were analyzed. There was a higher prevalence of males, patients from the countryside and the left unilateral transforaminal cleft subtype. 85.9% of the patients had undergone cheiloplasty and palatoplasty. About 74% of patients had dental agenesis, 71.9% developed the precanine tooth, 26.6% presented dental shape anomalies and 65.6% presented maxillary atresia. The mean DMFT index (decayed, missing, and filled teeth) of the patients was 3.51. These results corroborate and add valuable information to the available literature on cleft lip/palate patients. Our results demonstrate that cleft patients present dental and skeletal alteration that need specialized treatment.

Brazil has been suffering for many years from an extensive dengue epidemic. The objective of this study was to map dengue cases in Brazil between 2007 and 2022, correlating their epidemiology, geospatial distribution, and relationship to climatic and social data. An epidemiological survey was conducted based on data available in the Notifiable Diseases Information System, calculating incidence rates (IR), mortality rates (MR), case fatality rates (CFR), and the distribution of epidemiological characteristics, allowing the geolocation of cases and the creation of maps for each year and Brazilian states. Finally, the ecological determinants were correlated with IR and MR. We observed that IR and MR remained high throughout the analyzed period, with a slight decrease in IR in 2017 and 2018. Cases occurring in female individuals were higher, however, with a similar percentage of deaths. A decrease in the average mortality was observed, during the evaluation period, in children and adolescents; however, an increase in the average mortality among elderly was correlated with the presence of comorbidities. The states located in the Midwest region were the most affected, followed by the states in the Northern region. In addition, we observed a significant, but weak, correlation between ecological determinants (maximum temperature and humidity) and IR, GDP per capita and HDI (Human Development Index) with MR. Due to the hyperendemic scenario, it is necessary to take efficient control and constant epidemiological surveillance.

Brazil has a vast reserve of water resources, but pollution from various sources and the effects of climate change have triggered a crisis in this sector. The as-sessment of water quality indices plays a crucial role in monitoring and unders-tanding this issue, and the country has established its own standards and moni-toring requirements to guarantee water quality. In addition, the physical-chemical relationship plays a fundamental role in the conservation of both soil and water. In this context, a study was carried out in the Farinha river basin, located in Maranhão, in the Cerrado biome, over an area of 55,338.12 hecta-res. Data was collected at ten different points along the river during the rainy and dry seasons. A Van Dorn bottle was used to collect water samples at vari-ous depths, which were analysed for pH, dissolved oxygen, electrical conducti-vity and temperature. Nutrients such as potassium, calcium, magnesium, sodi-um, silicon, nitrate and total phosphorus were quantified using filtration and spectroscopy techniques. The data obtained was tabulated and subjected to analysis of variance, with the means analysed using the Tukey test. This study reveals significant seasonal variations in the physico-chemical parameters of the water in the Farinha River in Maranhão, impacting aquatic life and water quality. This highlights the importance of continuous monitoring and manage-ment of these resources.
Summary of Rock Damage Mechanics Classification
Authors: Li Zeyu
Published: September 2024

As an important means to study the mechanical properties and failure mechanism of rock materials and engineering mechanics, damage mechanics is often used to assist in the analysis of the failure process and mechanism of rock, metal, and other materials in the current research. In the use of damage mechanics to study the properties of rock materials and explore the deformation and failure law of rock, important research results have been achieved. The research methods of damage mechanics can be roughly divided into three types: statistical damage model, mesoscopic damage model, and continuous damage model. Based on the existing literature in hand, according to the division of damage mechanics research methods in the academic community, this paper collates and considers that the existing damage model construction can be summarized from the mechanical point of view. The pure theory is derived or fitted from the mathematical point of view. One of them is derived from the mechanism point of view, and the other is derived from the phenomenon point of view. The stress, strain, acoustic emission, and other data are analyzed and reconstructed, and both have advantages and disadvantages.
