Climatic and Anthropogenic Influences on Long-Term Discharge and Sediment Load Changes in the Second-Largest Peninsular Indian Catchment
Authors: Jadhav Harshada , Kandekar Avinash M. , Das Sumit
Published: December 2024

In recent decades, understanding how climate variability and human activities drive long-term changes in river discharge and sediment load has become a crucial field of research in fluvial geomorphology, particularly for South Asia’s densely populated and environmentally sensitive regions. This study analyses spatio-temporal trends in water discharge (Qd) and sediment load (Qs) in the Krishna basin, Peninsular India’s second-largest catchment. Using nearly 50 years of daily discharge, sediment concentration, and rainfall data from the Central Water Commission (CWC) and India Meteorological Department (IMD), we applied Mann–Kendall, Pettitt tests, and double mass equations to detect long-term trends, abrupt changes, and the relative influence of climate and anthropogenic effects. Results showed a notable decline in the annual discharge, with 15 of 20 stations showing decreasing trends, especially along the Bhima, Ghataprabha, and lower Krishna rivers. The annual stream flow data showed a 53% decline in the mean Qd from 26.01 × 109 m3 year−1 before 2000 to 12.32 × 109 m3 year−1 after 2000 at the terminal station. Eight of ten gauging stations showed a significant decrease (p-value < 0.05) in their annual sediment load, with a 76% reduction across the Krishna basin after its changepoint in 1983. The Pettitt test identified a statistically significant downward shift in discharge at seven stations. Double mass plots indicate that anthropogenic factors, such as large-scale reservoirs and water diversion, are the main contributors, accounting for 82.7% of sediment decline, with climatic factors contributing 17.1%. The combined trend analysis and double mass plots confirm these findings, underscoring the need for further study of human impacts on the basin’s hydro-geomorphology. This study offers a clear and robust approach to quantifying the relative effects of climate and human activities, providing a versatile framework that can enhance understanding in similar studies worldwide.
Effect of Heavy Rainfalls on Natural Organic Matter and Trihalomethanes in Surface Water Sources
Authors: Özdemir Kadir , Zeydan Özgür
Published: December 2024

Storm events have a notable impact on natural organic matter (NOM) and trihalomethanes (THMs). Water samples were collected and analyzed from Ulutan Dam (UD), in the Zonguldak region, Turkey. During four storm events, the data indicated the presence of hysteresis patterns in three of the four storms, with elevated concentrations of organic constituents observed during the falling limb of the hydrographs. It was observed that a higher specific THM (sp.THM) concentration (201.83 µg/L) was reached with an average specific UV absorbance (SUVA) value of 6.66 L/mg·m in the fourth storm. This means that the primary sources of THM precursors are the aromatic compounds present in NOM. A significant correlation between UV absorbance (UV254) and dissolved organic carbon (DOC) (R = 0.99–0.92) for all storms was observed. Chlorine demand also yielded a strong correlation (R = 0.81–0.99) with UV254 and DOC. Therefore, the present study indicates that UV254 can be an effective parameter for monitoring applicable chlorine dosage in drinking water treatment management as faced with storm events. On the other hand, the results of the study also provide valuable insight into the direct and indirect link between short-term precipitation events and their impact on the structural and THM precursors in surface water sources.
Electric Vehicle Charging Load Forecasting Based on K-Means++-GRU-KSVR
Authors: Shang Renxue , Ma Yongjun
Published: December 2024

The accurate short-term forecasting of an electric vehicle (EV) load is crucial for the reliable operation of a power grid and for effectively reducing energy consumption. Due to the fluctuations in EV charging loads, particularly the significant load variation between commercial and non-commercial areas, global models often suffer from prediction errors when forecasting loads. To address this issue, this paper proposes a regional forecasting method based on K-means++ clustering and deep learning algorithms. First, the K-means++ algorithm was used to partition the data into different regions, and an independent load-forecasting model was established for each region. Then, a combination of kernel support vector regression (KSVR) and gated recurrent unit (GRU) models was used to handle nonlinear features and time-dependent data, where particle swarm optimization (PSO) further optimized the model parameters to improve the forecasting accuracy. Finally, a weighted summation method was used to integrate the forecast results from each region, resulting in a more accurate overall load forecast. The experimental results show that the proposed model provided better prediction performance by capturing the spatiotemporal characteristics of the EV charging load, effectively addressing the challenges posed by regional differences, and outperforming the single-model forecasts.
Energy efficiency retrofit in the European social housing stock and the split incentive paradox : A comparative behavioural study
Authors: Dobi-Rózsa Anikó , Balaci Adrian
Published: December 2024

The social housing stock represents a considerable segment of the residential housing pool across Europe, as such, therefore, investing in its energy performance is
of great importance. Furthermore, social housing provides affordable homes for
the economically vulnerable, which adds urgency to the issue. Yet despite the social and environmental targets European states have agreed upon, the split incentive paradox has led to a widespread failure in advancing energy efficiency in the
sector. Taking a comparative behavioural approach, this study investigates the
social housing sector in three European countries with different governance and
rent-setting structures (representative of their respective regions) revealing distinct forms of split-incentive related market and behavioural failures. We find the
failures are most pronounced at the top of the social housing provision pyramid,
where provider and tenant interests often clash, leading to inefficient policies and
suboptimal refurbishment rates. In terms of solutions, we find the split incentive
challenge is effectively addressed when rent setting allows retrofit cost recovery,
tenants are involved in decisions and can carry forward energy efficiency benefits
when they change residence. To this effect, the introduction of alternative cost
recovery mechanisms is proposed, increasing the democratic legitimacy of the
process through active tenant participation, and developing regulations that protect the tenants’confirmed rights post refurbishment.

Published: December 2024

Nesse trabalho é apresentada a caracterização do canal MIMO-PLC (Multiple-Input and Multiple-Output - Power Line Communication) de baixa tensão, na faixa de frequências de 2 a 100 MHz. Com essa finalidade, foram realizadas diversas medições em quatro topologias de testes diferentes compostas por três fios de cobre de 2,5 mm2 transpostos em um eletroduto. Essas topologias se diferem por número e comprimento de derivações. Além disso, os experimentos são conduzidos com os fios energizados e desenergizados, e então seus resultados foram comparados. Os dados aferidos são os parâmetros de espalhamento, que associados às teorias de linhas de transmissão, culminaram em análises de perda por inserção, VSWR (Voltage Standing Wave Ratio) e impedância de entrada. A análise dos resultados mostraram a existência de faixas de frequências que podem ser utilizadas para transmissão de dados, e também que a rede energizada mostra um casamento de impedância muito superior aos casos desenergizados. Essas informações, avaliadas em conjunto com a impedância de entrada, permitiram mostrar que é possível melhorar ainda mais o casamento de impedância no projeto de acopladores, o que implica em menos reflexões e possivelmente uma melhoria na resposta do canal.
Limites e possibilidades para uma carreira do professor indígena na rede estadual do Ceará
Authors:   , Freitas Heveline Damasceno de
Published: December 2024

A presente dissertação, desenvolvida durante o Programa de Pós-Graduação Profissional (PPGP) em Gestão e Avaliação da Educação Pública da Universidade Federal de Juiz de Fora (CAEd/UFJF), discute o processo de estruturação da carreira dos professores indígenas da Rede Estadual de Ensino do Ceará, com o intuito de contribuir para a política de Educação Escolar Indígena. Na última década, os Planos de Educação Nacional e Estadual (CE) têm previsto metas para fomentar a valorização da carreira docente, a partir do tripé: formação inicial e continuada; piso salarial e carreira, estipulando estratégias específicas voltadas ao grupo dos professores indígenas, a exemplo da Meta 21, que trata sobre a criação do cargo de professor indígena. Entretanto, os professores indígenas cearenses atuam todos em vínculos precários. Esse cenário nos levou a definir a questão norteadora da pesquisa: “Quais os limites e as possibilidades para uma carreira do professor indígena no Ceará?”, sendo o objetivo geral da pesquisa investigar os desafios e possibilidades para a estruturação dessa, em atendimento aos Planos Nacional e Estadual de Educação. Para tal, partimos de três objetivos específicos: (1) descrever o contexto da educação escolar indígena no Brasil e no Ceará, espaço de atuação do professor indígena, considerando a legislação pertinente; (2) analisar os desafios e possibilidades para estruturação de uma carreira para esses profissionais na Rede Estadual do Ceará, considerando experiências realizadas em outros dois estados brasileiros: Bahia e Santa Catarina; (3) propor plano de intervenção com a finalidade de contribuir para o fortalecimento da carreira do professor indígena e sua valorização dentro da Rede Estadual. Atendendo a esse intuito, realizamos a análise sistemática e qualitativa dos documentos disponibilizados pelas Secretarias da Educação e entrevista com gestores envolvidos na política, demonstrando que a precarização dos vínculos dos professores indígenas promoveu uma evidente distância em termos de remuneração e de aperfeiçoamento e valorização desses profissionais em relação aos outros professores da rede, bem como, contribuiu para certa invisibilidade desse grupo nas ações promovidas pela Seduc, em que sua participação é condicionada à mobilização política. Em contrapartida, o ingresso do professor indígena na carreira docente possibilita rever a dinâmica dessa relação entre o Estado e a escola indígena. Diante dessas conclusões, nosso Plano de Ação propõe ações em prol do ingresso e desenvolvimento da carreira docente indígena, estabelecendo estratégias para sua efetiva inclusão na Rede Estadual do Ceará.

Published: December 2024

A presente dissertação tem por objetivo compreender qual a relação do trabalho dos teleoperadores nas Centrais de Teleatividades com a produção do valor no século XXI. Para isso foi realizada uma revisão bibliográfica que buscou sistematizar as principais questões a respeito do tema. Este estudo procurou aprofundar nosso conhecimento sobre a essência do modo de produção capitalista, apontando quais são suas principais categorias. Buscamos compreender como funciona o processo de valorização do capital e como o crescente avanço tecnológico influencia a produção do valor no século XXI, marcado pela fase financeira, informacional e digital do capitalismo. Por fim, procuramos compreender as características essenciais do Setor de Serviços, local onde se encontram as Centrais de Teleatividades, e do trabalho dos teleoperadores. O trabalho é uma relação social fundamental para existência da sociedade, estudar suas características mais profundas pode fornecer instrumentos importantes para análise da realidade. As Centrais de Teleatividades absorvem constantemente inovações tecnológicas e empregam um grande número de trabalhadores, sendo um espaço privilegiado para estudar algumas características do trabalho no mundo contemporâneo. Os resultados obtidos com esta pesquisa revelaram que o trabalho dos teleoperadores contribui direta ou indiretamente para produção do valor no século XXI, acelerando significativamente o tempo de rotação do capital. A produção em incessante de mercadorias necessita de um consumo com as mesmas proporções. Se uma mercadoria não é consumida, o capital colocado em circulação é perdido. Quanto mais rápido uma mercadoria é consumida, mais rápido poderá ocorrer a produção de uma nova. A mercadoria é uma forma assumida pelo capital e a produção, para o capitalista, nada mais é do que um meio para valorizá-lo.

Assessing the Challenges of Transitioning to Organic Fertilizers: A Case Study in Mahaweli System-B, Sri Lanka
Authors: Wijesundara W. R. A. Tharaka Prabhath
Published: December 2024

Mahaweli System-B, spanning the Polonnaruwa and Batticaloa districts of Sri Lanka, underwent a major shift in 2021 with the introduction of a government-mandated organic fertilizer subsidy program. This change aimed to promote eco-friendly farming by replacing inorganic fertilizers that had been used for decades. However, the transition posed significant challenges for farmers, particularly in the Dimbulagala Block, a key agricultural area known for its extensive paddy cultivation. This study investigates the constraints faced by farmers during this transition and evaluates their attitudes toward organic farming. Data were collected through a structured questionnaire survey conducted with 100 randomly selected farmers from six units of the Dimbulagala Block. Results revealed several critical barriers, including difficulties in transporting, storing, and applying organic fertilizers in field conditions. Farmers also expressed concerns about reduced paddy yields when using organic fertilizers, compared to traditional inorganic methods. Despite the availability of organic materials and training opportunities, these logistical and practical challenges significantly hindered adoption. Moreover, the study found variability in farmers’ adaptability based on their age, education level, and farming experience. The findings highlight the urgent need for improved infrastructure, such as better transport and storage solutions, and enhanced farmer support systems, including targeted training and financial incentives. Addressing these limitations could increase the acceptance and effectiveness of organic fertilizers, promoting sustainable agricultural practices in Mahaweli System-B and beyond.

Introduction: Chondrocytes are the major cell in hyaline cartilage playing a crucial role in maintaining the mechanical resilience of the tissue. We assessed the effect of an 808nm diode laser on the proliferation of human chondrocytes. Methods: This study was conducted on human chondrocytes in vitro. The cells were divided into 5 cases and one control group. The cells were irradiated by low-level laser 808 nm, with energy levels of 1, 2, 3 J/cm² (0.2 W, for 5, 10, and 15 seconds), 4 J/cm² (0.3 W,13 s), and 5 J/cm² (0.4 W,12 s). The culture was incubated for 24 hours. The MTT assay was performed to determine the cell viability. After 72 hours of incubation, the procedure was reperformed to assess the effect of incubation duration. The cell viability in terms of incubation duration and irradiation parameters were investigated by a two-way ANOVA test. Pairwise comparisons were performed using the Bonferroni test. Results: In the 72-hour incubation group, cell viability in the group that received 5 J/cm² energy was significantly lower than that in the groups receiving 1 J/cm², 2 J/cm² and 4 J/cm² irradiation. The variables of time (P=0.001) and energy level (P=0.024) had significant effects on the cell viability of the samples. In the 24-hour incubation groups, no significant difference in cell viability was observed. Conclusion: The diode 808 nm Low-level laser irradiation (LLLI) at doses of 5 J/cm² and less did not show a significant increase in the proliferation of chondrocytes (regardless of incubation time). However, the best survival rate of chondrocytes was observed in the group of 4 J/cm² with 72-hour incubation.

Published: December 2024

In this study, the potato excavator with loosening shovel was designed in order to solve the problems of serious soil obstruction and high excavation resistance during the potato harvest. Using EDEM discrete element simulation software, potato excavation simulation experiments were carried out on soil broken effects and excavation resistance. Through the comparative analysis with loosening shovel and without, the results showed that the increase of soil broken effects was close to 52%, and the excavation resistance decreased by 16.57%. Through the two-factor and three-level field orthogonal experiment with excavation depth and loosening depth as influencing factors, the optimal operating parameters was determined for potato excavators: the excavation depth was 23 cm and the loosening depth was 20 cm. At this time, the excavation potato rate was 98.21%, and the rate of damaged potato was 1.31%. The traction resistance was 1826 N, which met the requirements of relevant industry standards. Through comparative analysis of simulation experiments and field experiment, it was found that when the excavation depth was 23 cm and the loosening depth was 20 cm, the error value of traction resistance was 11.3% between simulation experiments and field experiments. The discrete element simulation analysis can provide a preliminary reference for potato excavation design.
MULTI-UAV TASK ALLOCATION AND PATH PLANNING METHOD FOR AGRICULTURAL PATROL SCENE
Authors: SHENG Li
Published: December 2024

A multi-unmanned aerial vehicle (UAV) task allocation and path planning model with the maximum endurance constraint was constructed specific to the agricultura l patrol scene. Moreover, an optimized ant colony optimization (ACO) algorithm applicable to grid map environment was proposed given such problems of the traditional ACO algorithm as limited path search direction and field of view, failure to find the shortest path and proneness to deadlock. This method preprocessed the grid map environment, extracted the feature points of obstacles, and selected such feature points as the way-finding access nodes; then, the construction efficiency of the solution was enhanced via the nonuniform pheromone distribution based on ACO algorithm, the guiding function of path search was strengthened using Tent chaotic mapping, and the pheromone evaporation coefficient was dynamically adjusted to prevent the algorithm from too early convergence. The experimental results show that the proposed method more conforms to the operational requirements of rotary-wing UAVs with limited cruising ability in comparison with the existing methods. Besides, the convergence efficiency of the improved ACO algorithm embedded with the niche genetic algorithm is 30.55% higher than that of the traditional ACO algorithm. The experimental results verify the practicability and effectiveness of the proposed method.

Authors: Flaga Andrzej , Flaga Łukasz
Published: December 2024

The work concerns dynamic similarity criteria of various phenomena occurring in hydraulics and fluid dynamics originally derived from ratios of forces and forces moments affecting these phenomena. The base of dynamic similarity criteria formulations and considerations is A.Flaga’s method and procedure for determining dynamic similarity criteria in different issues of fluid-solid interactions i.e. at different fluid-solid relative motions. The paper concerns the determination and analysis of dynamic similarity criteria for various practical problems encountered mainly in hydraulics and fluid dynamics at steady, smooth fluid onflow in front of a solid. Moreover, the cases of mechanically induced vibrations of a body in a stationary fluid moving with constant velocity in front of the body have been presented.
Enlightened Tribalism
Authors: Nobre Faria Filipe , Anomaly Jonathan , Willy Craig
Published: December 2024

Tribalism is often derided as a morally primitive form of human organization. But for most of human history, people organized themselves into tribes that facilitated collective action and provided their members with a sense of security and identity. In stark contrast, liberal cosmopolitans have promoted the ideal of the world community. They tend to diminish the moral importance of tribal attachments and instead claim that altruism should have a more universal scope. We argue that although tribalism can encourage needless conflict, it can also provide meaning, promote important virtues, and increase the long-run viability of human groups better than liberal cosmopolitanism. We call the view that we endorse “enlightened tribalism.” We end by identifying some of the problems tribalism can create, and distinguishing the kind of tribalism that leads groups of people to flourish from the kinds that lead to unnecessary suffering or self-destruction.
Monkeypox: epidemiological situation, diagnostics, prevention, new challenges and problems of our time
Authors: Belyakova Ekaterina N. , Shipulin G.A.
Published: December 2024

Monkeypox (mpox) is a particularly dangerous zoonotic infectious disease, the causative agent of which belongs to the numerous family Poxviridae, subfamily Chordopoxvirinae, genus Orthopoxvirus and belongs to the I pathogenicity group; genetically close to the smallpox virus [1]. Until recently, most cases of infection with orthopoxviruses were sporadic, did not lead to epidemic outbreaks and were difficult to register [2]. At the same time, it is believed that the formed immunity to smallpox is capable of protecting against infection with mpox at a level of 85% [3]. However, in the last decade, there has been a visible increase in the incidence of monkeypox [4], which cannot but cause concern. Over the past 50 years in Africa, sporadic incidence has increased from isolated cases to several thousand per year. At the same time, the number of cases of monkeypox virus (MPXV) transmission to humans is increasing, and imported cases of monkeypox are increasingly occurring, with the virus spreading beyond natural foci in Africa [5]. For example, in 2023, a new mpox outbreak began in the Democratic Republic of the Congo (DRC), with subsequent cases reported in Burundi, Kenya, Rwanda, and Uganda, and on 14 August 2024, the head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, declared the ongoing mpox outbreak a public health emergency of international concern under the International Health Regulations (2005), noting that a coordinated international response is needed to stop the spread of the disease. The situation in the DRC associated with MPXV clade I continues to evolve, with the number of cases steadily increasing since late 2022. The new outbreak is associated with new MPXV clade Ib strains that are spreading in the eastern provinces of the DRC and in countries bordering the DRC [6, 7]. This review aims to describe the current epidemiological situation, modern diagnostic capabilities and specific prevention of mpox. The review used publications presented in the main international medical information databases PubMed, Web of Science, Embase, Elibrary, as well as data from WHO, Centers for Disease Control and Prevention (CDC USA, ECDC, Africa CDC), NCBI GenBank and GISAID. An epidemiological method was used to analyze the publications.

Application methodology of the rapid response principle in production
Authors:   Boychuk M.I. Mikaeva S.A.
Published: December 2024

Today, Russian enterprises producing electronic equipment widely use a quality management system (QMS) based on two state standards: GOST R ISO 9001—2015 «Quality Management System. Requirements» and GOST VR 0015-002—2020 «System for the Development and Putting into Production of Military Equipment. Quality Management System. Requirements». The most important indicators of the QMS performance at the enterprise include a constant reduction in the number of defective products and a quick response on difficulties that arise in production. The specified GOSTs contain two main concepts that ensure the implementation of these procedures: corrective actions and preventive actions. The article proposes one of the possible models for organizing corrective and preventive actions called the «Rapid Response Principle». It allows you to quickly solve problems that arise in production, increase the share of good products, and significantly improve the quality of manufactured products.

„Bo choć czarną jak węgiel mam skórę, moje zamiary nie są ponure”. Przypadek Zwarte Pieta / Czarnego Piotrusia
Authors: Wekker Gloria
Published: December 2024

Przekład na język polski piątego rozdziału książki White Innocence Paradoxes of Colonialism and Race (2016). Wekker rzuca światło na kontrowersje wokół folklorystycznej tradycji Zwarte Piet (Czarnego Piotrusia) w Holandii. Rozdział ten obala dominującą w Holandii narrację, która przedstawia kraj jako pokojowe, tolerancyjne i nierasistowskie społeczeństwo. Wekker czyni to przez pryzmat kontrowersyjnej celebracji postaci w blackface, tradycyjnie kojarzonej z holenderskim świętem Sinterklaasa. Wekker rowniez analizuje symbolicznie przemocowe i naladowane emocjonalnie reakcje, które pojawiają się, gdy ten obraz holenderskiego społeczeństwa jest kwestionowany przez urasowionych aktywistów i międzynarodowych artystów.
Contesting the Colonial Archive, or Toward a Different Performativity of Images
Authors: Eusterschulte Birgit
Published: December 2024

In order to intervene in dominant historical narratives and overcome Eurocentric perspectives, artistic historicizations often draw on materials and documents from archives. Photographic media in particular have been instrumentalized for the project of European colonialism since their development, and have thus fixed colonial and Eurocentric perspectives firmly in the archives. With the question of the politics of showing and not showing historical photographs, the article discusses artistic methods of dealing with a violent and traumatic past and confronting the viewer with the violence of history and the persistent effects of the “imperial shutter” (Ariëlla Azoulay). An underlying question of the essay is how artistic forms of historicization can become productive as methodical unlearning and intervene in the perceptions and self-understandings of a (Western) audience.
Taktyka artystyczna jako konstruowanie sprawczości
Authors: Thùy Dương Đặng
Published: December 2024

Artykuł śledzi powiązania sztuki i taktyki społecznego działania. Refleksja zostaje sformułowana z pozycji artystki wietnamskiego pochodzenia działającej w Polsce. Lokując projekty często w przestrzeni peryferyjnej, to znaczy społecznej lub niegaleryjnej, artystka rozwija inne niż zastane powiązania transnarodowe. W artykule omawia projekty, w których przedstawia potrzebę ugruntowania modalności estetyki, otwierającej możliwości ponownego wyobrażenia siebie jako jednostki i jako grupy. Koncentrując się na tych niematerialnych aspektach sztuki, autorka pokazuje, jak konstruowanie odpowiedniej taktyki leży u podstaw jej działań artystycznych. Dotyka tym samym kwestii granicy tożsamości, sprawczości, transkulturowości, pozycjonalności i czasu.
