Vibroacoustic modeling of a compressor piping system
Authors: Mironova Tat'yana B. , Rekadze Pavel D. , Prokof'ev Andrey B.
Published: July 2024

The paper presents a finite element model of the compressor piping, developed in the Ansys software package using the APDL language. The finite element model was developed taking into account the real conditions of fastening pipeline sections in the form of installed supports. The calculation of the pipeline system began with the calculation of flow pulsations generated by the compressor, which were converted into pressure pulsations. The calculation results in the form of pipe vibration amplitude were obtained for each piping pipeline. The results obtained were compared with the vibration parameters recommended by GOST 32569-2013.

Authors: Criollo Martínez Ruby Alicia , Gutiérrez Zamora Eduardo Aquiles , Córdoba Guerrero Gustavo , Rodríguez Espinosa Diana Marcela
Published: July 2024

La Estructura Ecológica Principal (EEP) es fundamental para el ordenamiento territorial, ya que permite incluir criterios ambientales para el ordenamiento del suelo rural, el desarrollo de proyectos urbanísticos, de parcelación y edificaciones; no obstante, en muchos planes de ordenamiento territorial (POT) en Colombia el componente ambiental solo incluye las áreas protegidas legalmente establecidas y determinantes ambientales regionales como suelo de protección, insuficiente para la conservación de la biodiversidad y los servicios ambientales, esenciales para desarrollar procesos productivos sostenibles. La presente propuesta metodológica para el POT del municipio de La Florida se basó en el concepto de Estructura Ecológica de Soporte (EES), que abarca la EEP y la Infraestructura Ecológica (IE). La EES se apoyó en dos conceptos complementarios: la Estructura Ecológica de Soporte Actual (EESA) que la sociedad podría, o no, utilizar de manera sostenible y ser adecuada para mantener los servicios ecológicos y la Estructura Ecológica de Soporte Mínima (EESM) compuesta por áreas que deben protegerse, áreas críticas y áreas de uso humano directo. La EES permitió duplicar las áreas de conservación y protección ambiental de un 28,36 % requerido por la norma, hasta el 56,02 %, mediante la inclusión de la IE, compuesta por corredores de conectividad, cauces, nacimientos y áreas de protección asociada, áreas de recarga hídrica, laderas de protección y el parque temático ambiental “La casa del roble”. Así, la EES mejorará notablemente las condiciones biofísicas de los ecosistemas de las que dependen los servicios ecosistémicos.

Mechanical and Microstructural Analysis of Treated Tuff with Metakaolin Geopolymer Cement for Road Base layers Applications
Authors: Allali Khadhra , Bella Nabil
Published: July 2024

Traditional road bases materials such as natural gravel and crushed stone are environmentally damaging, and there is a growing need for sustainable and eco-friendly alternatives. One such alternative is using geopolymer cement and tuff as aggregate materials. Geopolymer cement is an innovative and environmentally-friendly alternative to traditional Portland cement, and using locally-sourced tuff as an aggregate material can further reduce the environmental impact of road construction. This article discusses the importance of sustainable road construction practices, particularly in the use of eco-friendly materials for road base layers. It focuses on the treatment of tuff with alkali-activated metakaolin as the geopolymer precursor activated with a mixture of sodium hydroxide and sodium silicate. The effectiveness of treating tuff with metakaolin geopolymer cement is evaluated using several parameters, including dry density, California Bearing Ratio (CBR), shear strength, and microstructure analysis. These evaluations are performed with different NaOH dosages (8, 10, and 12  moles) to determine the optimal molarity for enhancing the material's performance.

Published: July 2024

Con la aprobación del matrimonio igualitario, mediante sentencia de la Corte Constitucional N. 11-18-CN/19, surge un problema en cuanto a los derechos conexos propios del pacto solemne entre los cónyuges. Uno de ellos es la adopción, el cual está expresamente definido para parejas de diferente sexo en la norma constitucional. Esta investigación busca analizar la improcedencia y negativa del acceso a la figura de la adopción para familias homoparentales sobre el requisito que el derecho impone a los solicitantes, es decir, ser heterosexuales, lo cual genera una contradicción en los artículos 67 y 68 de la Constitución, así como de algunos artículos del Código de la Niñez y la Adolescencia y del Código Civil. A lo largo de esta investigación se detallaron aspectos resaltantes sobre la homoparentalidad, la perspectiva del niño como sujeto de derecho, la teoría de la adopción como un falso derecho y de la idoneidad de los adoptantes homoparentales; se desarrolló un marco conceptual con los términos más importantes; y se concluyó con un recorrido por los aspectos legales y jurisprudenciales. La metodología se fundamentó en un diseño no experimental, exploratorio descriptivo, transeccional o transversal, utilizado un enfoque predominantemente cualitativo. Se concluye que sí existe tal contradicción al para imponer un criterio moralista por encima de los principios superiores del niño, criterio que se aleja de la exegética jurídica al concebir la adopción como un mero trámite y no como un auténtico derecho de los menores a tener figuras parentales que contribuyan a su desarrollo holístico.

A Study of Parents’ Perceived Constraints on Participating in Outdoor Leisure Activities with Their Children in Japan
Authors: Uesugi An
Published: July 2024

Outdoor activities have been shown to have numerous positive impacts. As children's time spent in nature decreases, it is important to move beyond just encouraging children to go outside and instead urge the entire family to spend time together in natural surroundings. While cultural norms influence family behavior, there is currently insufficient research on family leisure in Asian countries to allow comparisons. The purpose of this study is to clarify the outdoor leisure constraints of Japanese parents with children and examine the relationship between these constraints and participation frequency in outdoor leisure activities with children. A web-based survey was employed to obtain responses from parents (n = 193) whose children were between 3 and 11 years old. This study clarified four constraining factors affecting Japanese parents: psychological, physiological, and environmental; accessibility; commitment; and time. Accessibility constraints were a key driver in predicting the frequency of participation in outdoor leisure activities.

Anti-turbulent efficiency of oil-soluble polymer solutions and colloid systems flowing through cylindrical channel
Authors: Manzhay Vladimir N.
Published: July 2024

Relevance. The use of anti-turbulent additives for transporting hydrocarbon liquids through main pipelines allows  reducing significantly the energy consumption of pumping power stations. Aim. Comparative analysis of the anti-turbulent efficiency of high-molecular polymers and compositions of surfactants. Methods. Laboratory-scale experimentation aimed to study the flow of dilute polymer solutions and dispersed surfactant systems through a cylindrical channel of a turbulent rheometer. Results. The author has carried out the comparative experimental studies of the anti-turbulent efficiency of extremely dilute solutions of polymers and colloidal systems. The results were obtained that suggest a higher anti-turbulent efficiency of high-molecular-weight polymers compared to micellar surfactant systems. Solutions of high molecular weight polybutadiene and aluminum polyhydroxydicarboxylates in gasoline were used as samples for the experimental comparison of hydrodynamic efficiency. The paper describes the laboratory setup, on which the studies were carried out, and introduces the formulas used for quantitative calculations. The structure of polymer solutions and colloidal systems is considered and a theoretical explanation is given for the preferential use in industrial practice of high-molecular polymers in extremely low concentrations in real pipelines. It was found out that the mechanisms of degradation of antiturbulent properties of polymer solutions and dispersed surfactant systems are different. This is due to the difference in the structure of macromolar coils of polymer with an immobilized solvent and that of micelles from low molecular amphiphilic compounds. The paper introduces the arguments that explain the degradation of the antiturbulent properties of polymers not by the destruction of carbon-chain macromolecules, but by decomposition in a turbulent flow of the original large associates, consisting of a large number of chains, into individual and smaller macromolecular coils with an immobilized solvent.
Social platforms as Tools for Inclusive Pedagogy: Case of Perusall for Collaborative Reading
Authors: Ateh Comfort Muyang
Published: July 2024

Extant literature is replete on the importance of inclusive pedagogy, which is crucial in engaging every student irrespective of their background to have access to knowledge. Although social platforms like Perusall aim at collaborative reading and enhance students’ engagement in reading, literature is sparce on the extent to which these tools accommodate the learning needs of diverse learners. This study is a contribution to close the gap by exploring the Perusall website, research reports on Perusall, and the author’s personal experience with Perusall to determine features of the platform that can contribute to diverse learners engaging in collaborative reading. This paper focuses on features in Perusall that can enhance accommodation of learning needs for diverse learners and discusses how instructors can be intentional in leveraging the features to be inclusive for collaborative reading and learning in diverse learners. The paper highlights the features of Perusall that instructors can leverage through the lens of Universal Design for Learning that defines multiple forms of representations, engagement, and actions at the core of inclusive pedagogy.

The study utilized a case study approach to select a group of 64 prospective teachers from the faculty of education at a state university in Türkiye. The study participants comprised 34 female and 30 male prospective teachers. The researchers employed a purposive sampling technique, specifically the criterion sampling approach, to select the prospective teachers included in the study. The researchers collected data for the study using the "AI Perception Interview Form" and the "AI Future Foresight Determination Form," and then analyzed the data using descriptive and content analysis techniques. The results showed that prospective teachers obtained information about AI primarily from social media, internet/news websites, and applications. Analyzing the definitions and explanations provided by the prospective teachers revealed that they particularly emphasized the uploading of human intelligence to computer systems, the acquisition of human-like abilities by machines, and the ability of AI to learn independently. Additionally, prospective teachers identified health, education, accounting, and finance as domains with significant potential for the advancement of AI. In education, the initial applications prospective teachers thought AI could be used for included determining students' mental states, assessing student levels, and providing personalized content. The data obtained from the study indicate that prospective teachers produced both utopian and dystopian content regarding the future of AI. This production of varied content reveals that prospective teachers have diverse perspectives on the future of AI.

Published: July 2024

Endolymphatic Sac Tumor is a local aggressive tumor that grows slowly, associated with Von-Hippel-Lindau disease and originated from endolymphatic canal. A 64-year-old male patient with VHL disease admitted to the neurosurgery department of our hospital and presented pain behind the ear and loss of sensation on the cheek. Cranial magnetic resonance imaging revealed an aggressive tumor located in the middle ear and left acoustic canal and extending to the pontocerebellar angle that eroded the mastoid and temporal bones. Histopathological examination of the lesion revealed a simple cuboidal epithelium forming glandular and papillary structures. The patient diagnosed with endolymphatic sac tumor as the presence of the morphological findings, positive staining with immunohistochemical markers such as Vimentin, NSE, EMA, PAX8, Cytokeratin 7. Our case showed neuroectodermal origin, which is even rare for von Hippel-Lindau disease, and has been discussed with histopathological findings and differential diagnosis.

Published: July 2024

Evaluation ecosystem service value (ESV) is critical for “lucid waters and lush mountains are invaluable assets”. However, the ESV estimation and spatial-temporal analysis for mountainous soil erosion area is rare, e.g., Changting county, China. In this study, we developed a remote sensing driven mountainous equivalent factor (RS-MEF) method to estimate the ESV of soil erosion area in subtropical mountain. It is a hybrid of a conventional equivalent factor framework and the remote sensing techniques for mountains, and achieves several highlights of spatial adjustment using carbon sink with vegetation canopy, improvement spatial resolution, and removal topographic effect. Using the RS-MEF method, we estimated that the ESV of Changting county was about 15.80 billion CNY in 2010 and 34.83 billion CNY in 2022. Specifically, the ESV per unit area of major soil erosion area (MSEA) in the county was less than that of non-major soil erosion area (n-MSEA), however, the ESV growth rate of MSEA from 2010 to 2022 was faster than that of n-MSEA. Therefore, the ESV gap between two areas was shortened from 28.99% in 2010 to 15.83% in 2022. Topographic gradient effect analysis illustrates that the area with high elevation and small slope is one control focus in the next step. Our study indicates that the ecological restoration in the county has made great achievements in the ESV perspective, with low ESV area shrank evidently in MSEA; and the achieved knowledge of the ESV growth and inherent factors is valuable and instructive for the next soil and water conservation.

Published: July 2024

Weather conditions appear to be undergoing significant deviations from the long-term average, marked by pronounced extremes of heat, prolonged droughts, and heightened rainfall occurring with greater frequency worldwide. Consequently, new patterns of extreme weather are emerging, like the unusual and unorganized tropical cyclone called "Yaku", that influenced the extreme amount of rain that between March 6th to 10th, 2023 hits more than 1000 districts in the northwestern of Peru. One of the district more affected was Íllimo, in the Lambayeque province, due to the river that pass through the city, so called “La Leche”, after the continuous and intensive rain overflow devastating his surrounding areas and causing victims and damage. This emergency provided and excellent opportunity to apply, on the aforementioned areas, the “change detection” technique, that allows identifying areas of change between data obtained before and after of emergency events. In this research, optical data (Sentinel-2, Landsat, MODIS Terra and Aqua, and PeruSAT-1) and synthetic aperture radar (SAR) data (Sentinel-1 and COSMO SkyMed) were analyzed. A benchmark could also be carried out between open-source and commercial spatial analysis tools. The results indicated that in an extreme rain event the optical data are obscured by clouds and do not allow their use, while SAR data overcome clouds, and can be used for this research. The benchmark indicated that using the Jaccard index score, the Sentinel-1A set showed a 33% of correlation, while COSMO SkyMed demonstrated a 38% of match between the maps. The results obtained could be used to sensitize the population and develop a better management of future emergency events (floods) in different areas of Peru.

Authors: Kaplan Jeffrey B. , Sukhishvili Svetlana A. , Sailer Milosalv , Kridin Khalaf , Ramasubbu Narayanan
Published: July 2024

The extracellular matrix of most bacterial biofilms contains polysaccharides, proteins, and nucleic acids. These biopolymers have been shown to mediate fundamental biofilm-related phenotypes including surface attachment, intercellular adhesion, and biocide resistance. Enzymes that degrade polymeric biofilm matrix components, including glycoside hydrolases, proteases, and nucleases, are useful tools for studying the structure and function of biofilm matrix components and are also being investigated as potential antibiofilm agents for clinical use. Dispersin B is a well-studied, broad spectrum antibiofilm glycoside hydrolase produced by Aggregatibacter actinomycetemcomitans. Dispersin B degrades poly-N-acetylglucosamine, a biofilm matrix polysaccharide that mediates biofilm formation, stress tolerance, and biocide resistance in numerous Gram-negative and Gram-positive pathogens. Dispersin B has been shown to inhibit biofilm and pellicle formation; detach pre-formed biofilms; disaggregate bacterial flocs; sensitize pre-formed biofilms to detachment by enzymes, detergents, and metal chelators; and sensitize pre-formed biofilms to killing by antiseptics, antibiotics, bacteriophages, macrophages, and predatory bacteria. This review summarizes the results of nearly 100 in vitro and in vivo studies that have been carried out on dispersin B since it’s discovery 20 years ago. These include investigations into the biological function of the enzyme, it’s structure and mechanism of action, and its in vitro and in vivo antibiofilm activities against numerous bacterial species. Also discussed are potential clinical applications of dispersin B.

Published: July 2024

Bluetongue is not a contagious disease. It spreads very quickly and uncontrollably, considering that it is a vec-tor-borne disease transmitted by the genus Culicoides. Climate change has led to the fact that vectors and dis-eases have spread to the top of Northern Europe, causing great economic losses in livestock production. Even greater problem is controlling the disease, because numerous species of domestic and wild ruminants are sus-ceptible to bluetongue. The most effective tool against bluetongue disease is vaccination. There is no ideal vaccine against bluetongue virus (BTV) due to the serotype diversity of the strains. Thus, there is need for a vaccine for at least for 24 clinically significant serotypes. Sometimes it is difficult to obtain the desired amount of vaccine against a defined serotype on the market, and this led to the need for a new vaccine against blue-tongue disease. We tested an experimental inactivated novel vaccine against BTV4. Master seed BTV4 has been examined and characterized by sequencing. The novel BTV4 vaccine induce the onset of immunity at least at day 21 after the application of the first dose in more than 80% of vaccinated individuals, while specific antibodies against BTV are detected by the ELISA test for more than a year. Along with our laboratory results, the preliminary results of safety and efficacy trials are also presented. The side effects of novel vaccine are within the limits of permissible local reactions without generalized changes of health status, while the serology and challenge test leads to the conclusion that novel vaccine protects high percentage of vaccinated individuals against BTV4 or causes a significant reduction in the intensity and duration of the clinical signs in the vac-cinated sheep. Based on the trial results, new vaccine has given encouraging results in quality, safety and pre-liminary efficacy tests. Thus, we believe that a new vaccine against BTV is on the horizon. Keywords: bluetongue virus, inactivated vaccine, candidate, quality of vaccine, safety, efficacy We confirm that neither the manuscript nor any parts of its content are currently un-der consideration for publication with or published in another journal. All authors have approved the manuscript and agree with its submission to Vaccines.

Authors: Wu Yigao , Zhang Yunqing , Li Yixuan , Tin Hiu , Yan Xu , Li Yanchun
Published: July 2024

Background: Cardiometabolic risk factors (CRFs) are significant health concerns among adults with overweight and obesity. Resistance training (RT) is known to manage CRFs, but the impact of moderate-frequency RT (two to three times weekly) remains unclear.
Methods: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing moderate-frequency RT with non-exercise control or usual care in overweight and obese adults. Searches were performed in PubMed, Web of Science, EMBASE, and Cochrane Library up to February 2024, following the PRISMA 2020 guidelines. Eligible studies included non-athletic adults (BMI ≥ 25) aged 18 years or older, with RT interventions lasting 7 weeks or longer.
Results: Fifteen RCTs were included. Moderate-frequency RT significantly reduced systolic blood pressure by -4.66 mmHg (95% CI -9.34 to 0.02, p=0.01) and mean arterial pressure by -6.48 mmHg (95% CI -10.63 to -2.33, p=0.002) compared to controls. Additionally, RT significantly lowered fasting insulin levels by -12.52 mmol/L (95% CI -24.17 to -0.88, p=0.04) and HOMA-IR by -1.49 (95% CI -1.63 to -1.35, p＜0.00001). Improvements were more pronounced in participants with dietary control.
Conclusion: Moderate-frequency RT effectively improves CRFs in overweight and obese adults, suggesting its potential as a beneficial intervention for this population.

Controlling the money supply from macroeconomics perspective: Saving interest and exchange rate
Authors: Goestjahjanti Francisca Sestri
Published: July 2024

The M2 money supply over the last five years has tended to increase by 10-12%, which is allegedly due to macro factors, namely, low savings interest and increasing exchange rate requirements, causing rising inflation rates. This research aims to determine the influence of savings interest and the exchange rate on the money supply in Indonesia for the 2004-2023 period. The analysis technique used in this research is linear regression with annual time series data of 20 observation units. This simultaneous model has never been studied by previous researchers. The results of this research analysis provide information that every change in savings interest negatively affects the M2 Money supply by 78.60% and a significant, positive effect between the Exchange Rate and Money in circulation by 78.40%. Meanwhile, simultaneous changes in savings interest and exchange rates have a significant effect on changes in money supply in Indonesia and the influence is substantial at 91.20%. Therefore, the conclusion of this research is, that partially and simultaneously the proposed model exhibits a significant influence between savings interest and the exchange rate on the amount of money circulating in Indonesia. Therefore, it is crucial to pay attention to the current macroeconomic conditions concerning these two factors, especially the stability of the exchange rate, to ensure that it does not increase the money supply and inflation which may reduce people’s purchasing power in Indonesia.

Dynamic model of magnetic transmission
Authors: Kovalenko Mykhaylo , Tkachuk Ihor , Kovalenko Iryna , Zhuk Serhiy , Kryshnov Oleg
Published: July 2024

In the work, a non-contact electromechanical energy converter with permanent magnets, which is known as magnetic transmission, is studied. Magnetic transmissions have certain structural advantages compared to mechanical transmissions, namely: high reliability, efficiency, lower losses, non-contact transmission of mechanical power, no maintenance costs, and simplicity of construction. The use of magnetic transmissions for systems of conversion of low-potential mechanical energy into electrical energy is especially relevant: wind energy, water energy, energy of mechanical vibrations, etc. The use of magnetic gearboxes in autonomous wind power plants can be more promising from an economic and technical point of view compared to traditional mechanical transmissions. A numerical simulation mathematical model of magnetic transmission with permanent magnets has been developed. The use of magnetic transmission, for example, for autonomous wind power systems allows to increase the reliability of the operation of such installations, reduce operating costs and increase the efficiency of their operation. In emergency modes of operation, the use of magnetic transmission allows to avoid destruction or emergency shutdowns of electrical equipment. The developed simulation model of magnetic transmission takes into account the pulsations of the electromagnetic moment due to the discrete structure of the magnetic transmission and the change of the model parameters when the input moment changes: pulsations, losses in the magnetic core and permanent magnets, the change of the load angle and the transmitted electromagnetic moment. A feature of the developed model of the magnetic transmission system is that a change in the load of the electric power source leads to a change in the operating point on the mechanical characteristics of the rotor of the wind turbine. Conversely, when the wind parameters change, the output parameters of the source of electrical energy change: power, voltage, current and electromagnetic moment.

Annak ellenére, hogy nemzetközi színtéren számos eredményes intervenció és ajánlás érhető el, amelyek az olvasási motiváció erősítését segíthetik, magyar nyelvű, a pedagógiai gyakorlatot támogató útmutatás alig található ebben a témában. A tanulmány első része az olvasási motiváció elméleti alapjait tekintette át. A második rész a nemzetközi szakirodalom alapján javaslatot tesz hét, a mindennapi osztálytermi gyakorlatba beépíthető, olvasási motivációt támogató alapelvre, amelyek a következők: (1) célok kitűzése, (2) tapasztalatszerzés és az előzetes ismeretek aktiválása, (3) érdekes szövegek alkalmazása, (4) autonómiatámogatás, (5) kompetenciaérzés és a pozitív énkép támogatása, (6) szociális motívumok és a kollaboráció támogatása és (7) megfelelő értékelési eljárások alkalmazása. Az egyes alapelvek megvalósítását gyakorlati ötletek segítik. Az alapelvek bármelyik olyan tantárgyi tartalomhoz hozzákapcsolhatók, amelyek írott szövegek tanulói feldolgozására épülnek.

Az érzelmi intelligencia fejlesztése az óvodai anyanyelvi nevelésben
Authors: Major Tünde Kármen
Published: July 2024

A nyelvi-kommunikációs képességek szerepe a nevelés-oktatás rendszerében kimagasló, mértékük a tanítás és a tanulás folyamatában befolyásolja az eredményességet – akárcsak az emocionális állapotok felismerése, meghatározása és az önirányítás elsajátítása. Az óvodai színtéren a pedagógusok bármely spontán kialakuló vagy tudatosan tervezett folyamatban alakítják a három–hét éves gyermekek anyanyelvi és kommunikációs képességeit, érzelmi intelligenciáját. A tanulmány összegzően ismerteti az óvodai anyanyelvi és érzelmi nevelés célját, feladatait és sajátosságait. Bemutatja, hogy a Gordon-módszer eszközeinek érvényesítése és gyakorlása, az óvodapedagógusok mintaadó tevékenysége és segítségnyújtása révén, milyen formában járul hozzá a nyelvi-kommunikációs képességek fejlesztéséhez. Gyakorlatban kibontakoztatható játékokat sorakoztat fel, amelyek az óvodai csoport szokásrendszeréhez illeszkedve hozzájárulhatnak az érzelmek tudatos kifejezéséhez, a szókincs gazdagításához. Végül pedig egy foglalkozásvázlatot közöl, amely szemlélteti, hogy a papírszínház és az anyanyelvi fejlesztő játékok bevonása miként járul hozzá az óvodáskorú gyermekek kommunikációs kompetenciáinak az alakításához.
Earthquake ruptures in viscoelasticity unbounded by classical speed limits
Authors: Weng Huihui
Published: July 2024

Classical theories using linear elasticity predict that crack propagation is bounded by a limiting speed, beyond which the energy balance becomes unphysical. Recent experiments in viscoelastic materials demonstrated that both tensile and frictional crack propagation can exceed classical speed limits. However, the fundamental physics governing unbounded rupture speeds are still unclear. In this paper, we show via numerical simulations that frictional ruptures in viscoelasticity can propagate at a continuum of terminal speeds that are not bounded by the classical speed limit. All simulated rupture speeds are predicted by the newly developed theory of fracture mechanics incorporating viscoelasticity via the principle of energy balance. In addition to the ratio of the fracture energy to the static energy release rate that can be used to uniquely predict the rupture propagation in linear elasticity, the scales of characteristic lengths in viscoelasticity also govern the energy balance. Beyond the classical speed limit, the energy balance becomes independent of any macroscopic length and is controlled only by the local properties around the rupture tip. These numerical and theoretical findings fundamentally advance our understanding of dynamic rupture propagation.
Enhancing Hydropower Resilience and Grid Stability with Interpretable and Customizable AI Amid Climate Change

Climate-driven water cycle changes have led to a global hydropower decline, exacerbating power shortages and grid risks. Here we developed HydroTrace, an AI model featuring a customizable attention mechanism rooted in Earth system processes. It enables hydropower stakeholders to identify the climate and environmental factors that have the most significant impact on their operations. HydroTrace outperforms conventional methods in the Third Pole, a region heavily reliant on hydropower, sensitive to climate changes, and lacking in data. It reveals that glacier-related runoff significantly affects hydropower generation. Projections up to 2100 predict increased spill periods (when runoff exceeds a hydropower station’s capacity) by 13-21 days and decreased low-flow production by 14.0-19.3%. This leads to an overall reduction in generation by 0.4-4.4% at the facility being studied. With its precision and adaptability, HydroTrace serves as a vital tool for the development of climate adaptation strategies and the formulation of energy sector policies.
Assessing the Feasibility of Alternative Wetting and Drying (AWD) Technique for Improving Water Use Efficiency in Dry-Season Rice Production
Authors: Phoeurn Chan Arun
Published: July 2024

AWD has been effective in conserving water in various regions, particularly in Asia. However, there is a lack of research on the feasibility of AWD in different paddy soil ecosystems. We evaluate the possibility of saving water in dry rice production in Cambodia by quantifying the effects of AWD on rice yield and water use efficiency (WUE) with varying varieties and soil properties. We tested AWD at two different threshold levels: AWD15, when the perched water table drops to 15 centimeters below the soil surface, and AWD20, when it drops to 20 centimeters below the soil surface. Five field experiments were conducted from 2021 to 2023.
Our results showed that AWD did not significantly affect grain yield, yield components, HI, and root growth compared to conventional flooding (CF). However, AWD did improve WUEs when considering soil properties. WUE was not improved in AWD when the top soil was sandy clay loam. Despite similar yields, AWD significantly reduced total water inputs by 10-30% in AWD15 and by 22-24% in AWD20 compared to CF. Among the AWD treatments, AWD15 exhibited the highest WUE.
The finding demonstrates that safe and mild AWD has potential for rice growing on sandy loam, and WUE could be improved further in AWD when implemented on soil with low saturated conductivity, regardless of its texture.

Analysing Train Delay Impacts on Subway Stations via a Three-stage Approach: An Empirical Study on Shanghai Metro

Published: July 2024

Delays can adversely affect passengers, operational efficiency, and punctuality, necessitating effective methods to identify and analyse stations vulnerable to such delays. This study proposes a three-stage analytical framework. In the first stage, the 3σ rule is utilized to define normal passenger volume ranges and establish a specific time window, focusing on periods significantly affected by delays. Next, a multivariate time series clustering method is proposed to identify stations with stable demand and high volume, considering passenger volume differences both among and within stations. In the final stage, the effects of delays on these key stations are assessed by examining duration, starting, and ending times, and passenger volume variation, providing a comprehensive analysis of delay impact. The proposed method is validated on a real-world case: the 2021 delay incident at Shanghai Metro's Longyang Road Station. Our case study revealed that stations significantly impacted by delays are not limited to the specific line or direction of the delay, but also include opposite direction and network transfer stations. The starting time of effects at stations occurs in three stages—prior to, during, and after the delay—with full recovery at most key stations not occurring until the third time window. Additionally, both increases and decreases in passenger volumes due to the delay present considerable implications. Our results aid transit managers in better managing delays, thereby improving passenger satisfaction and operational efficiency. This paper also offers a comprehensive framework and an empirical study, providing valuable guidance for future research in this area.
