The global population increase during the last century has significantly amplified freshwater demand, leading to higher wastewater (WW) production. European regulations necessitate treating WW before environmental. Microalgae have gained attention for wastewater treatment (WWT) due to their efficiency in remediating nutrients and pollutants, alongside producing valuable biomass. This study investigates the phycoremediation potential of a Chlorella-like strain isolated from urban WW in a 600L-scale system under winter conditions. Experiments in December 2021 and February 2022 tested the strain’s adaptability to varying environmental conditions, particularly temperatures (min-max temperature range: from −3.69 to 10.61 °C in December and −3.96 to 17.61 °C in February), and its ability to meet legal discharge limits. In December, low temperatures algal growth. Nitrates showed an RE of about 92%, while ammonia slightly decreased (RE, about 32%), and phosphorous remained unchanged. In February, mild temperatures increased algal density (33.3 × 106 cell mL−1) and, at the end of experiment, all nutrients were below legal limits with very high RE % (NH4+, 91.43; PO43− 97.32). Both trials showed an E. coli RE, % = 99%. The study highlights the potential of microalgae for WWT and the importance of considering seasonal variations when implementing these systems.

Published: September 2024

Large-scale urban water distribution network simulation plays a critical role in the construction, monitoring, and maintenance of urban water distribution systems. However, during the simulation process, matrix inversion calculations generate a large amount of computational data and consume significant amounts of time, posing challenges for practical applications. To address this issue, this paper proposes a parallel gradient calculation algorithm based on GPU hardware and the CUDA Toolkit library and compares it with the EPANET model and a model based on CPU hardware and the Armadillo library. The results show that the GPU-based model not only achieves a precision level very close to the EPANET model, reaching 99% accuracy, but also significantly outperforms the CPU-based model. Furthermore, during the simulation, the GPU architecture is able to efficiently handle large-scale data and achieve faster convergence, significantly reducing the overall simulation time. Particularly in handling larger-scale water distribution networks, the GPU architecture can improve computational efficiency by up to 13 times. Further analysis reveals that different GPU models exhibit significant differences in computational efficiency, with memory capacity being a key factor affecting performance. GPU devices with larger memory capacity demonstrate higher computational efficiency when processing large-scale water distribution networks. This study demonstrates the advantages of GPU acceleration technology in the simulation of large-scale urban water distribution networks and provides important theoretical and technical support for practical applications in this field. By carefully selecting and configuring GPU devices, the computational efficiency of large-scale water distribution networks can be significantly improved, providing more efficient solutions for future urban water resource management and planning.
Study on the Effect of Liquefiable Overburden Foundations of Rockfill Dams Based on a Pore Pressure Model

Published: September 2024

China’s southwestern region boasts abundant hydropower resources. However, the area is prone to frequent strong earthquakes. The areas surrounding dam sites typically have deep overburden, and the liquefaction of saturated sand foundations by earthquakes poses significant safety risks to the construction of high dams in the southwest. The effects of liquefaction and reinforcing measures on the foundations of rockfill dams on liquefiable overburden under seismic action are currently the subject of somewhat unsystematic investigations. The paper utilizes the total stress and effective stress methods, based on the equivalent linear model, to perform numerical simulations on the overburden foundations of rockfill dams. The study explores how factors such as dam height, overburden thickness, liquefiable layer depth, liquefiable layer thickness, ground motion intensity, and seismic wave characteristics affect the liquefaction of the overburden foundations. Additionally, it examines how rockfill dams impact the dynamic response, considering the liquefaction effects in the overburden. The results show that although the total stress method, which ignores the cumulative evolution of pore pressure during liquefaction, can reveal the basic response trend of the dam, its results in predicting the acceleration response are significantly biased compared to those of the effective stress method, which comprehensively considers the cumulative changes in liquefaction pore pressure. Specifically, when the effect of soil liquefaction is considered, the predicted acceleration response is reduced compared to that when liquefaction is not considered, with the reduction ranging from 4% to 30%; with increases in the thickness and burial depth of the liquefiable layer, the effective stress method considering liquefaction significantly reduces the predicted peak acceleration; the effect of liquefiable soil on the attenuation of the speed response is more sensitive to the low-frequency portion of the seismic wave. The study’s findings are a significant source of reference for the planning and building of rockfill dams on liquefiable overburden.

Published: September 2024

A hydrogeological study of the shallowest part of the halite nucleus of the Salar de Atacama is presented, focusing on the isotopic variability in δ18O and δ2H (SMOW) in the brine. It is observed that intensive brine extraction has induced upward vertical flows from the lower aquifer, which presents with a lighter isotopic composition (δ18O: −0.87‰ to −2.49‰; δ2H: −26.04‰ to −33.25‰), toward the upper aquifer, which has more variable and enriched isotopic values. Among the possible explanations for the lighter isotopic composition of the lower aquifer waters is the influence of paleolakes formed during the wetter periods of the Late Pleistocene and Holocene that recharged the underlying aquifers. The geological structure of the Salar, including faults and the distribution of low-permeability layers, has played a determining role in the system’s hydrodynamics. This study emphasizes the need for continuous and detailed monitoring of the isotopic composition to assess the sustainability of the water resource in response to brine extraction and future climate changes. Additionally, it suggests applying this methodology to other salt flats in the region for a better understanding of hydrogeological processes in arid zones. The research provides an integrative view of the relationship between resource extraction, water management, and ecosystem conservation in one of the most important salars in the world.
Impact of Land Use/Cover Change on Soil Erosion and Future Simulations in Hainan Island, China
Authors: Guo Jianchao , Chen Jiadong , Qi Shi
Published: September 2024

Soil erosion (SE) is a critical threat to the sustainable development of ecosystem stability, agricultural productivity, and human society in the context of global environmental and climate change. Particularly in tropical island regions, due to the expansion of human activities and land use/cover changes (LUCCs), the risk of SE has been exacerbated. Combining the RUSLE with machine learning methods, SE spatial patterns, their driving forces and the mechanisms of how LUCCs affect SE, were illustrated. Additionally, the potential impacts of future LUCCs on SE were simulated by using the PLUS model. The main results are as follows: (1) Due to LUCCs, the average soil erosion modulus (SEM) decreased significantly from 108.09 t/(km2·a) in 2000 to 106.75 t/(km2·a) in 2020, a reduction of 1.34 t/(km2·a), mainly due to the transformation of cropland to forest and urban land. (2) The dominant factor affecting the spatial pattern of SE is the LS factor (with relative contributions of 43.9% and 45.17%), followed by land use/cover (LUC) (the relative contribution is 28.46% and 34.89%) in 2000 and 2020, respectively. (3) Three kinds of future scenarios simulation results indicate that the average SEM will decrease by 2.40 t/(km2·a) under the natural development scenario and by 1.86 t/(km2·a) under the ecological protection scenario by 2060. However, under the cropland protection scenario, there is a slight increase in SEM, with an increase of 0.08 t/(km2·a). Sloping cropland erosion control remains a primary issue for Hainan Island in the future.
The Influence of Various Ethnic Groups on the Formation of the Military Organisation in the Umayyad State in al-Andalus
Authors: Koşdaş Yaşar Emrah , Gümüş Nebi
Published: September 2024

This study examines the contributions of various ethnic elements within the military structure of the Umayyad Caliphate of al-Andalus and their roles in maintaining order. Utilising qualitative research methods, including historical document analysis and ethnographic techniques, the research reveals that Arabs initially held central military and administrative roles but were purged due to rebellions and replaced by loyal groups such as the Mawālī and Sakālibe, leading to a new military organisation. The loyalty of the Mawālī and the reliability of the Sakālibe brought them to the forefront of military and administrative services. The Muwallads and Berbers also assumed significant military roles, but rebelled during periods of weakened political authority. The findings demonstrate that the distrust towards rebellious groups transformed the military structure, and that ethnic diversity played a crucial role in shaping security strategies. The prominence of certain ethnic groups during specific periods, while others were purged by the state, serves to illustrate the dynamic changes that occurred in the state's military organisation.

Published: September 2024

The purpose of the article is to analyze the structure of the sources of the formation of financial resources of agricultural enterprises of Ukraine and to assess the influence of the state of war on their dynamics. In the course of the research, there were used methods: analytical method and method of comparisons – to assess the dynamics and structure of sources of financing of agricultural enterprises; the method of building analytical tables – for summarizing the results of the analysis; expert method – for determining the problems of financial support of agricultural enterprises of Ukraine and substantiating proposals for their solution. The conducted research emphasizes the importance of the activities of agricultural enterprises to ensure food security of Ukraine and the world. In view of this, the access of agricultural enterprises to sources of financing based on fair competition is a significant factor and incentive for their further activity. It was found that the main source of financing for agricultural enterprises of Ukraine currently remains own funds, however, the level of self-financing in 2022 compared to 2021 significantly decreased, in particular due to military actions, occupation of territories, reduction of exports, and disruption of logistics. The war and its negative consequences made it necessary to increase the volume of external sources of financing, in particular credit resources, including Вісник Чернівецького торговельно-економічного інституту. 2024. Вип. І (93) 194 through the creation of favorable lending conditions based on the state program "Affordable loans of 5-7-9%" during the period of martial law and within a month after its end. Opportunities for agricultural enterprises of Ukraine to attract sources of financing are expanding through the receipt of state subsidies, targeted, subsidized credit programs, loans and technical assistance from the EU and other international donors. The activities of agricultural enterprises in the conditions of martial law and the need for post-war reconstruction of the agricultural sector indicate the perspective of further scientific research into the study of various sources of financing agricultural enterprises as a factor in development of the national economy, increasing the export potential of the agricultural sector of Ukraine, ensuring world food security.

Published: September 2024

The article describes the problems of budget financing of institutions of vocational education and training. The authors researched the actual budget expenditures in Ukraine by educational levels in the period since 2019 to 2023 and drew conclusions about the effectiveness and prospects of such funding. In particular, it was found that the main part of education expenses is being financed from local level budgets, which receive an educational subvention from the State budget. The authors have found out that the funding of vocational education in Ukraine is not given due attention and is insufficient. The lack of interest of local authorities in financing vocational education and training is explained both by unresolved property issues and by the lack of funds in local budgets, which causes public controversy both in the public area and between state administration bodies of different levels. However, the authors note that the government has launched several positive initiatives aimed at improving the situation. In particular, we are talking about the initiative to create training and practice centers (TPCs) at institutions of vocational education and training with funds earmarked as part of the educational subvention from the State budget. In addition, attention is focused on problem of unpopularity of the segment of vocational education, while at the same time there is a significant need for specialists in work specialties, especially in the period of recovery after the war. Also, the legislative framework for financing education in Ukraine as a whole and of vocational technical institutions in particular was investigated. As a result, non- budgetary sources of vocational technical education funding have been singled out. It is obvious that only state financing of vocational training institutions is not sufficient, so it is necessary to expand the practice of attracting donor organizations' resources. As a successful example, the EU4Skills and Skills4Recovery projects are given, which are fixed by the German government and are aimed at supporting the reform of vocational education in Ukraine.

Published: September 2024

The nonlinear Schrödinger equation (NLSE) describes various types of physical systems such as water waves, nonlinear optics, plasma Physics. In optics, NLSE describes a wide range of non-linearity effects in fiber optics. The solution to the above equation might be examined in order to investigate these consequences. Differential configurational entropy (DCE) is used to analyze the dark similariton solution in this specific situation of NLSE with bright and dark similariton solutions. DCE provides us with the measure of information required to examine stability for various physical systems and to characterize a systems spatial profile using the Fourier transform. It is show that even for the same solitonic solution of the NLS equation, the variations in the spatial shape is induced by different choices of the relevant parameter α. The global minima of the DCE correspond to the saturation of the breadth of dark solitons. While dark similariton waves propagate through waveguides, such low entropic values result in minimum dispersion of momentum modes, and this should be taken into consideration while designing the waveguides.

This study aims to investigate the total chemical component, biological activity and chromatographic analysis of the fruit extract of Styrax officinalis, obtained from local markets trading local products in the Gaziantep region. Methanol was used to extract the pericarp and seed samples that make up the fruit. Fruit pericarp extract with high phenolic content showed a significant capacity in all antioxidant activity analyses. No antibacterial activity of the extracts was observed against the standard strains used. Regarding phenolic acid content, the most abundant phenolic acid in the fruit pericarp extract was chrysin and t-cinnamic acid. In contrast, in the seed extract, it was t-cinnamic acid and quercetin. HPLC results revealed that succinic acid was the main component of organic acid contents in all extracts. The fact that the main components determined from all analyses have various strong pharmacological activities reveals the importance of the widespread use of S. officinalis.

Published: September 2024

En este trabajo se exploran, desde un abordaje arqueológico, las relaciones entre la materialidad del primer Monumento Conmemorativo a la Bandera Nacional Argentina y los aspectos simbólicos. Este monumento, construido en las islas frente a la ciudad de Rosario, en el año 1873 por el ingeniero municipal Nicolás Grondona, consistía en una pirámide ubicada sobre una plataforma doble con escalón, un pedestal que aparentaba un tronco piramidal y una aguja propiamente dicha con forma de obelisco. Para esta construcción fueron utilizados ladrillos, baldosas y adoquines, obtenidos por subscripción pública y donaciones de empresarios locales (materiales no sólo accesibles sino también transportables en embarcaciones a través del río Paraná). La corta duración del monumento, derrumbado por una creciente, ocasionó la pérdida de sus restos materiales y tangibles. Los trabajos arqueológicos en la zona donde pudo haber sido erigido no dieron resultados totalmente positivos respecto a su registro material. Esta situación implica que se está frente a lo que podría llamarse una “arqueología de ausencia”, donde los restos arqueológicos son suplantados por su descripción documental. Sin embargo, la postura presenta un notable dilema: ¿es arqueología o es historia? Finalmente, y como tema concreto de discusión, se trata de plantear arqueologías específicas, emergentes y hasta cierto punto creativas, que permitan (re) construir realidades que, de otro modo, resultarían inaccesibles, dentro de un pasado histórico del que no siempre se dispone de sus restos.

Combining intuition with corpus linguistic analysis: A study of marked lexical chunks in four Chinese students’ undergraduate assignments
Authors: Leedham Maria
Published: September 2024

In the literature on lexical chunks, a dichotomy is frequently implied between intuitionbased methods of finding language ‘formulaic’ and frequency-based means of extracting ‘n-grams’. In this paper, a case study of four Chinese students’ undergraduate assignments is described in terms of marked or atypical lexical chunks revealed through close reading and those found through keyword analysis, when compared with a reference corpus of similar writing by British undergraduates. The paper discusses the benefits of combining the two approaches, arguing that this gives clearer insights into the personal phraseological profiles of the students’ writing than either can offer alone.

Authors: Masood Maria
Published: September 2024

This paper presents a comprehensive study on the design, analysis, and
performance of Metal-Insulator-Metal-Insulator-Metal (MIMIM) multilayer
stacks. The behavior of these stacks was modeled using the Transfer
Matrix Method (TMM), allowing for a detailed investigation into their
optical properties under varying parameters such as refractive index,
layer thickness, polarization, and angle of incidence. The results
highlight significant trends, including the effects of changing the
incidence angle and layer thickness on reflection dips and absorption
peaks, which exhibit wavelength-dependent shifts and intensity
variations. These finding are particularly relevant for optimizing
selective emitters in thermophotovoltaic (TPV) systems, where specific
resonant peaks are desirable for efficient energy conversion. By
adjusting the thickness of the metal and insulator layers, the study
demonstrates how precise control over multilayer parameters can enhance
performance, particularly through the strategic tuning of Fabry-Perot
cavities within the stacks. The insights provided pave way for future
applications in photonic and optoelectronic devices.
Discursos periodísticos de la represión estatal en Colombia y México, 1968-1982. Un estudio comparativo
Authors: Gil Pérez Anderson Paul
Published: September 2024

This article analyzes the role of the political press in the construction of public opinion during the processes of state repression in Mexico and Colombia between 1968 and 1982. Its objective is to analyze the types of discourses through which the major political press influenced the way in which readers interpreted the dynamics of state repression in both countries. A historical-comparative analysis of two cases is carried out to review the journalistic positions of the primary sources, in this case, the newspapers Excélsior, El Sol de México, El Informador, El Tiempo, El Siglo, El Espectador and La República. The results reveal that the press promoted seven main discourses on state repression: 1) youth and university co-optation, 2) public order violated, 3) subversion and terrorism, 4) institutions, security and the state, 5) the external enemy, 6) human rights as a violation of national sovereignty and 7) the press as a guarantor of public opinion. These discourses positioned newspapers as actors in the political contest and in the construction of public opinion in the context of recent history.

This study is a reflexive method practice that pretends to improve the teaching-learning processes through experience and the use of theory. This is how intergenerational programs based on solidarity and dialogue are approached as a support tool for a problem that is evident in the classrooms and that has an impact on the class dynamics, as well as on the academic student's achievement and their mental health. Day after day, significant problems such as depression, anxiety, and suicide in young students are increasing. Therefore, it is proposed a theorical and exploration approach by addressing the axes of reflective practice: professional scenario, personal experience, and reflection, visualizing the viability of intergenerational programs proposed by the authors approaching as critical- reflective prototypes from which there are undoubtedly several actions and lines of research to work, to achieve the validation and creation of this in the future. Taking as a case study the Autonomous University of Ciudad Juarez, where we seek to have a first approach to make a proposal related to intergenerational programs at higher education Institutions. With this theorical approach and multiple readings from international solidarity, dialogue, and existing programs from other parts of the world, the evidence allows us to think that this knowledge's proposal, development, and application enable the teachers to position themselves as an active agent of transformation and formation.

Communities' participation in the declaration and management of protected natural areas (ANP) is studied to determine whether their operation meets their inhabitants' requirements and economic needs. The research uses a quantitative approach based on applying a Likert-type survey, which was conducted on 323 fishermen and inhabitants of two fishing communities located in the Gulf of Baja, California, Mexico. The results show that interaction with government authorities is not constant, and the fishermen's opinion was not considered in decision-making, which limits the search for solutions for fishing communities. It is concluded that without the active participation and support of fishermen in the planning and operation of the ANPs, government initiatives for their conservation and good management will have little chance of being effective.
Challenges in Making Inclusive and Comprehensive Public Policy on Ethno-educational Processes

Published: September 2024

This article presents the results of intercultural processes stemming from challenges in making inclusive and comprehensive public policies on ethno-educational matters based on the current public policies in Latin American countries, particularly Colombia. This qualitative, ethnographic research examined the perceptions of Indigenous educators vis-à-vis (sustituir por: in face of) the contemporary public policies on aboriginal communities. In doing so, this study employed individual and focus-group interviews and drew on a descriptive, analytical design that also considered a systematic review of antecedents to such policies. The findings evidence that the realities of Indigenous classroom practices and approaches are distant from those of urban settings and the principles and norms established in Colombia’s legislation and other countries. Lastly, the study highlights the need for constructing public policies that benefit Indigenous communities in Latin America and Colombia.

Auditory skills in the teaching-learning of English are a fundamental ability when it comes to learning a second language. In this context, the present exploratory research involves an analysis of several ICT tools and their suitability for teaching auditory skills. Throughout the text, a brief description of each technological tool identified is presented to assess their characteristics and uses in various academic contexts. In methodological terms, this is documentary-based qualitative research, elaborated by means of a survey of documentary sources of proven academic value, under a perspective close to educational phenomenology, interested in describing people's learning experiences without confirmatory theoretical biases. In its general conclusions, the research showed that, in the educational field, the integration of ICT not only facilitates access to authentic and updated materials but also allows for a more personalized and continuous evaluation of students' progress. This does not mean that these tools are infallible or can respond to all the needs and expectations of all learning communities, but beyond this reality, ICTs are an option in constant development.

The impact issue and development of e-governance on shortening the terms of public service provision is urgent for ensuring the efficiency of government agencies. The public service delivery terms affect the effectiveness of the state's public policy and is directly related to citizen engagement in digital e-governance. The article aims to determine the effectiveness of e-governance and calculate the relationship with the terms of public service delivery by using correlation analysis. The article analyses the impact of e-governance on reducing the public service delivery terms among a sample of developed countries that have the highest level of digital public administration. The research employed a correlation analysis method between the E-government Development Index and the average term of providing various public services in the ten most developed countries in the field of e-government. The main principles of the formation and development of e-governance are described, and the efficiency of which, according to the E-Government Development Index (EGDI), is 0.95 and 0.97 in developed countries. The main empirical aspects of the proportionality between e-governance and a 25% reduction in public service delivery terms were studied, which is a positive result. The obtained results were interpreted, where a correlation analysis was performed with a resulting inclination of 2.03, which indicates a close relationship between electronic services and the citizen engagement. Further prospects for the development of e-governance are outlined with the aim of reducing bureaucratic processes and potential opportunities to shorten public service delivery terms through the use of digital technologies.
