Authors: Suresh Kumar Vaisakh , Tagotra Niharika , M A Ijas
Published: February 2025

To reach India’s declared goal of net zero emissions by 2070 and a cumulative RE capacity of 500 GW by 2030, the states will need to actively participate in the effort. This working paper focuses on Kerala, which has set more ambitious targets of becoming a 100 percent RE-based state by 2040 and achieving carbon neutrality by 2050. Kerala imports approximately 70 percent of its electricity, mostly from fossil fuel sources. As part of its plan to transition to clean energy, the state is in the process of expanding its RE capacity. Kerala has a complex terrain and geography, with eco-sensitive zones. Suitable wind-rich sites and land for large-scale solar projects are limited. In this context, it is important to explore a wider set of RE options and related technologies that could benefit the state.

This study was conducted to evaluate the effect of natural and commercial feeds on the hematological characteristics of red drum Sciaenops ocellatus. At different durations up to 30 days of feeding, blood samples were collected from the caudal vein. Biochemical analyses were conducted, and blood smears were prepared and stained with Giemsa. The results showed that the number of erythrocytes fluctuated from 2.07 to 6.32 × 106/μL, the percentage of leukocytes was about 0.34 to 4.80%, and platelets ranged from 0.14 to 4.49% compared to the number of erythrocytes. Pearson correlation (r) between the cell morphological parameters, such as the erythrocyte length and width, with the length, width and area of the nuclei of erythrocytes was not greater than 0.30, while in the group of fish consuming natural feed, the correlation coefficient between cell length and width with the area were 0.57 and 0.52 respectively. In both groups of fish, we found many types of morphological disorders of erythrocytes associated with the cell membrane, and disorders associated with the cell nucleus were expressed at a low level. In addition, the study results also provided biochemical data of red drum such as glucose (1.8 – 22.4 mmol/L), urea (0.6 – 1.7 mmol/L), creatinine (12.1 – 43.2 µmol/L), triglyceride (2.5 – 10.7 mmol/L), AST (4.7 – 68.9 U/L), ALT (0.3 – 6.1 U/L) and protein (21.0 – 49.2 g/L). Overall, these findings contribute to understanding the health and physiological responses of red drum, offering valuable data for optimizing feeding strategies in aquaculture.

Published: February 2025

Steel is costly and detrimental to the environment when used as a reinforcement. Another technique for reinforcing concrete is fibre reinforcement. Fibre is a small amount of reinforcing material with specific properties. Fibre-reinforced concrete has several uses and is available in several shapes. Cellulose fibre, glass fibre, steel wire fibre and steel raw material have the following percentages: 0.5%, 0.7%, and 1%; 0.3%, 0.6%, and 1%; and 0.5%, 1%, and 1.5%, respectively. Specific percentages of different fibres, ranging from 0.3% to 1.5%, are employed in this study to assess the ductile behaviour of concrete since the primary objective of utilising these fibres is to enhance the ductile qualities of concrete. The fibre-added specimens are subjected to four distinct kinds of tests. It has been demonstrated that concrete’s flexural strength, split cylinder strength, and double punching strength have increased by up to 28%, 60%, and 93%, respectively, compared to the control mix concrete. Steel and raw material fibre exhibited no detrimental impacts on compression at certain percentages; however, glass fibre and cellulose fibre reinforcements had detrimental effects, reducing the compressive strength by up to 33.5% and 49.3%, respectively.

Published: February 2025

Innovative community based monitoring programs and citizen science projects have become transformative forces in the field of marine science and
conservation, including local inhabitants as active participants in ongoing research activities. These programs enable people to actively engage in data
gathering via thorough training and cooperative efforts, providing insightful information on the complex dynamics and health of marine ecosystems.
Community participation in Marine Protected Areas (MPAs) is noteworthy because it introduces co-management practices and gives locals a crucial role
in enforcing legislation and managing marine resources sustainably. In this complex strategy, education plays a key role as a foundation for awareness
and transformation. Customized initiatives intentionally incorporate marine science into community workshops and school curriculum to provide a
deep understanding of marine ecosystems. Using immersive field excursions and interactive workshops as well as other experiential learning strategies
improves understanding and fosters a greater feeling of accountability for ocean conservation. Additionally, programs within this paradigm aggressively
acknowledge and incorporate indigenous and cultural knowledge, which successfully closes the knowledge gap between traditional ecological wisdom
and mainstream science.
Exploring the Interplay Between Urban Morphology and Microclimate in Urban Heat Island Formation

Published: February 2025

It has been observed that the formation of urban heat islands depends on a lot of factors like meteorological conditions and specific characteristics of a city. Among the major contributors to the creation of an urban heat island are urban parameters like the usage of materials of low albedo, design of urban geometry, high population density, and presence of anthropogenic heat sources together aggravating the problem. The phenomenon of urban climate is becoming more and more complex at both local and global levels due to its multiple interconnected variables. Such elements include the built environment, strategies for urban design, urban morphology, building density, coverage with vegetation, height and orientation of buildings, distance between buildings, exposure to sunlight on road surfaces, and wind patterns. Each of these factors plays a critical role in determining the thermal dynamics of urban areas. For example, street-level wind velocities can significantly influence the development of a city's thermal microclimate by either facilitating or hindering the dispersal of heat. The interaction of these factors results in the amplification of heat retention within the urban environment, often leading to a noticeable temperature difference compared to surrounding rural areas. The objective of this paper is to examine and synthesize earlier studies about the relationship between the shape of urban morphology and its influence on the microclimate, especially with regard to the development of urban heat islands. The better the dynamics at play are understood, the better urban planners and environmental scientists can address and mitigate the effects of urban heat islands.
Investigation of Groundwater Contamination from the Use of Fertilizers, Pesticides and Herbicides on Agricultural Lands in Parts of Kaduna State Using Electrical Resistivity Imaging Technique
Authors: G Cyril Afuwai , Abraham Ema
Published: February 2025

Fertilizers, pesticides and herbicides contain toxic chemicals which leach into groundwater bodies resulting in the generation of high Biological Oxygen Demand (BOD), and thus contaminating the groundwater system. In order to save the environment from further degradation, a geophysical investigation was carried out across agricultural lands at Kaura Local Government Area (LGA) of Kaduna State, Nigeria where prevalent use of fertilizer, pesticides and herbicides is a norm. The research aims to delineate areas of possible contamination plumes and their migration path. For this purpose, Electrical Resistivity Tomography (ERT) data were acquired along six (6) Traverses and the results were inverted using the RES2DINV Software. Distinct low-resistivity zones adjudged to represent the contamination plumes were obtained from the ERT results. Water samples collected from boreholes, hand-dug wells and river channels were also analyzed. The analyzed water samples results revealed that the total dissolved solids (TDS) ranged between (2.30x101 - 8.20x101) μScm-1 as against the Nigerian Standard for Water Quality (NSDWQ) value of 1x103 μScm-1. Biochemical Oxygen Demand (BOD), chemical oxygen demand (COD) and dissolved oxygen (DO) values ranged between 1-10, <2 - <98 and 0.01 - 0.12 mg/L respectively. The water samples had detectable levels of Cu, Cd, Ni, Mn, Pb and Zn contents which were below the permissible limits, and microbiologically revealed the presence of faecal contamination with bacteria pathogens such as Coliform and Escherichia coli, whose levels were above the acceptable limit while the mould yeast and total aerobic were below the permissible limit. Ultimately, the results obtained showed that the agricultural land constitutes a serious threat to groundwater bodies in the area.

Published: February 2025

Cetacean mortality events in the Arctic often go underreported compared with events in more highly populated regions. Here, we report a mortality event involving the death of 11 bowhead whales around the Gulf of Boothia, Canada. The whales were discovered between October 2020–April 2021. Reports of 11 dead bowhead whales within six months in one area raised concerns among local hunters and community members. Due to the remoteness of these strandings and challenges with access, complete necropsies were not performed, but local Inuit collected tissue samples from eight of the whales. Possible reasons for these deaths include unusual weather events, nutritional stress/starvation, metabolic abnormalities, infectious disease, anthropogenic impacts (such as vessel collisions) and killer whale predation. To determine the most likely cause of these strandings, demographic, temporal, environmental, epidemiological, pathologic and contaminant analyses were performed. Results were compared with published accounts and historical data where appropriate. Killer whale sightings by local Inuit both before and during the stranding events confirmed the presence of these predators in close proximity to the carcass locations, with predation marks observed in several carcasses. We conclude that this was the most probable direct contributing factor to the mortality event. Indirect contributing factors might also include reduced ice coverage as a result of climate change and nutritional stress. Further monitoring of this population is required to assess health from both a scientific and an Indigenous perspective.
The Effects of Cooperative Brand Experience, Length of Membership and Members Loyalty: A Proposed Value Co-Creation Behavior Conceptual Framework
Authors: Malik Akmal Nashren Bin Abd , Yacob Yusman Bin , Ali Jati Kasuma Bin
Published: February 2025

In recent years, there has been growing scholarly interest in value co-creation. Previous research highlights its essential role in the growth and long-term viability of the consumer cooperative sector. However, while much of the current literature focuses on identifying the components and drivers of value co-creation, there remains a lack of insight into its impact on behavioural factors. By using Service Dominant (S-D) Logic theory and supported by Experiential Learning theory, this paper aims to introduce a behavioural framework for value co-creation, incorporating cooperative brand experience, length of membership and member loyalty within the context of consumer cooperatives in Sarawak. Although prior studies have explored the relationship between value co-creation behaviour and loyalty, there has been limited research investigating the role of knowledge factors, particularly how cooperative brand experience and length of membership serve as moderators. Moreover, the application of these concepts within the context of cooperatives in emerging markets remains underexplored. To fill this gap, this conceptual paper aims to propose a value co-creation behavioural framework that incorporates cooperative brand experience, length of membership and member loyalty, viewed through the lens of consumer cooperatives in developing markets.

Das flores no jardim a um vivenciar religioso: a abordagem freudiana da crença e da descrença
Authors: Albuquerque Bruno Pinto de
Published: February 2025

As elaborações de Sigmund Freud sobre religião a cultura tornaram-se conhecidas através de suas obras O futuro de uma ilusão e O mal-estar na cultura. Entretanto, uma pesquisa mais aprofundada mostra detalhes significativos também em textos pouco estudados, dentre eles, Uma experiência religiosa, escrito justamente no ínterim entre os dois livros mencionados. A origem deste texto remonta a uma entrevista concedida por Freud ao jornalista George Sylvester Viereck, na qual conversaram sobre o valor da vida. Incomodado com a atitude de Freud frente à crença em uma vida após a morte, um médico estadunidense escreve-lhe relatando sua própria experiência religiosa e exortando-o a converter-se ao cristianismo. O criador da psicanálise constrói hipóteses sobre essa conversão, destacando o papel central da ambivalência afetiva frente à figura paterna. Ao ser posteriormente retomado por Theodor Reik, o texto freudiano revela ainda o lugar fundamental ocupado pelas dimensões do olhar e da voz na conversão religiosa, articulados à angústia de castração. Em Dostoiévski e o parricídio, Freud novamente se depara com um caso de luta com a descrença que resulta em uma conversão religiosa. Este percurso pretende salientar possibilidades e limites da investigação psicanalítica das motivações inconscientes para as crenças e as descrenças.

This investigation analyses the allelopathic effects of aqueous extract of Lepidium sativum (garden cress) against the annual weed Phalaris minor (red rescue grass). This weed is a known problem in wheat crops. The application of Lepidium extracts with different concentrations of 0 to 80 percent was made over P. minor seeds in the laboratory and the growth parameters including the root and shoot length, fresh weights, germination percentage, mean emergence time, germination index and time to 50 percent emergence were analyzed. The lepidium extract was analyzed using HPLC and quercetin, gallic acid, vanillic acid, and p-coumaric acid were identified as the phenolic compounds responsible for allelopathic effects. The conclusion drawn is that there were significant concentration-dependent effects of Lepidium sativum extract on Phalaris minor. Root length was inhibited at 80 percent by 47 percent of the control, whereas shoot length exhibited a potential hormetic response and increased by 25.6 percent at 20 percent. There were variable responses of fresh weights and germination parameters across the extract treatments. A biphasic dose-response model identified an EC50 value of 12.4 percent for root length. The study showed that Lepidium extracts possess significant allelopathic potential against P. minor and can be helpful in sustainable weed management. However, the complex dose-dependent responses, including the hormetic effects, should be considered carefully for practical applications. The study contributes to the research on plant-derived allelochemicals with the potential for eco-friendly weed control while highlighting the importance of dose-response relationships in allelopathic interactions. Further field studies are required to validate the findings under real-world conditions. It also calls for broader ecological studies to recognize the potential adverse implications of artificial allelopathic procedures on the environment.

Real-Time Tracking and Distance Measurement of Opencv Aruco Marker Using Webcam
Authors: Ali Shuja Sardar
Published: February 2025

Object tracking and distance measurement play a vital role in robotics and drones. It is often challenging to measure the distance of a target object in an environment by just using a single-vision camera. This paper discusses the development of a fiducial marker-based object tracking and distance measurement system. Fiducial marker detection uses the ArUco method based on the OpenCV library and Python 3.x. The hardware consists of an Arduino, a single-vision camera, and two servos as an actuator for tracking. A mathematical equation is derived to measure the real-time distance of the marker by using a single camera and adjusting the frame size and the camera output colors to increase the detection method’s performance. OpenCV is used to find the center coordinates of the bounding box, and a tracking algorithm is applied to give pan/tilt angles to the servos. Finally, to stabilize the tracking mechanism, an acceptable error is defined. The accuracy of the system is measured by performing 100 trials, and the results show a good accuracy for the system when tracking the ArUco marker. The system is highly beneficial for indoor mobile robot navigation and drone applications

Published: February 2025

The topic of the article is the EU’s dependence on imports from China and the implementation of mechanisms to protect the common market against threats from China. UE’s exports and imports with China lead to imbalance in merchandise trade and geopolitical threats. In this context, an alternative to China emerges in the form of an agreement to create the world’s largest free trade area between the EU and Mercosur. This agreement is part of the EU’s geopolitical strategy, and both parties aimed to sign it by the end of 2023, but it still has not been ratified. This paper seeks to analyze the EU’s trade dependence on China. The research question is formulated as follows: Considering opportunities and threats, is Mercosur a viable alternative to the EU’s dependence on China in terms of merchandise trade? In this context, the article shows a new factor that became very important is the environmental impacts of the trade agreement.

Authors: KHMELYARCHUK Mariya , RATUSHNIAK Marharyta
Published: February 2025

This research explores operational efficiency strategies in the airline industry based on the analysis of different operational models in airline industry, with especial emphasis on their ability to operational adjustments during disruptive periods. The study also aims to investigate the differences between low-cost carriers (LCCs) and full-service carriers (FSCs) operational models by analyzing how their prospecting and defending strategies affect their responses to crises like the COVID-19 pandemic, as well as their recovery patterns. The research methodology is based on the case study approach, which make it possible to analyze the airline industry adaptation to changes by comparing its different segments on the example of two airline companies: a low-cost airline, Ryanair, and a full-service carrier, Air France-KLM.

The research results proved distinct approaches of LCCs and FSCs to economic pressures and operational challenges, particularly in response to major threats like the COVID-19 pandemic. The assessment of operational efficiency in LCCs versus FSCs shows clear strategic variations, each presenting unique advantages and disadvantages. By analyzing case studies and performance metrics, this study highlights how each business model adapts to financial constraints, customer service and regulatory demands. In particular, LCCs focus on operational efficiency to gain cost leadership, while FSCs prioritize operational resilience by maintaining a delicate balance between service quality and complex operational structures. The decision between these models depends on the airline’s strategic goals, yet both methods provide useful perspectives for improving operational performance within the wider airline sector.

Keytruda should not be covered for patients who have received or planned to receive radiation therapy before or after surgery, and/or who are receiving other drugs before surgery to shrink a tumour or stop its spread. Also, Keytruda should not be covered to treat patients who have had previous treatment with drugs that change how the immune system works.
Keytruda should only be reimbursed if it is prescribed by clinicians with expertise in managing lung cancer and the price of Keytruda is reduced.
The Urgency of Legal Regulation for Personal Data Protection in Indonesia in the Big Data Era
Authors: Hukom Suratman , Humi Nurma , Lukman Ilham
Published: February 2025

The rapid development of big data has significantly increased the risk of personal data breaches in Indonesia, highlighting the need for stricter regulations to safeguard personal information. Although Law No. 27 of 2022 on Personal Data Protection (UU PDP) has been enacted, its implementation still faces several challenges, including weak oversight mechanisms and low corporate compliance. This study aims to analyze the effectiveness of the UU PDP in providing legal protection for personal data in Indonesia and compare it with the General Data Protection Regulation (GDPR) in the European Union. Using a normative legal approach and comparative legal methodology, this research examines Indonesia’s data protection regulations and contrasts them with international standards. Findings indicate that more than 60% of companies in Indonesia have not yet fully complied with the UU PDP, while cases of data breaches have increased significantly. Major incidents include the leakage of 279 million BPJS Kesehatan user records in 2021 and 91 million Tokopedia user records in 2020. Additionally, 75% of Indonesian internet users remain skeptical about the security of their data in digital transactions. Compared to the GDPR, the UU PDP still has weaknesses in terms of enforcement and sanctions. While the GDPR imposes fines of up to 4% of a company’s global revenue for violations, the UU PDP still imposes relatively low penalties. This study contributes to policy recommendations aimed at strengthening the implementation of the UU PDP, including the establishment of an independent authority responsible for personal data protection and the enhancement of penalties for violators
Spatial and temporal evolution of future atmospheric reactive nitrogen deposition in China under different climate change mitigation strategies
Authors: Ma Mingrui , Cao Jiachen , Tong Dan , Zheng Bo , Zhao Yu
Published: February 2025

Abstract. Atmospheric reactive nitrogen (Nr) deposition plays a crucial role in linking air pollution to ecosystem risks. Previous modeling studies have indicated that climate change and pollution controls jointly result in significant changes in Nr deposition in China. However, it remains unclear how future emission reductions will influence Nr deposition under different climate pathways. Here, we investigated the spatiotemporal evolution and driving factors of future Nr deposition under various national clean air and climate policies. We applied WRF-CMAQ and assessed the historical (2010s, 2010–2014) pattern and future changes of Nr deposition till the 2060s (2060–2064) in China, by combining two Shared Socioeconomic Pathway (SSP) and Representative Concentration Pathway (RCP) global climate pathways and three national emission control scenarios. The results show that the implementation of clean air and carbon neutrality policies would greatly reduce oxidized nitrogen (OXN) deposition, mitigate the adverse perturbations of climate change, and reduce the outflow from Eastern China (EC; 20–45° N, 110–125° E) to the western Pacific. In Northern China (NC; 30–45° N, 110–125° E), the weakened atmospheric oxidation capacity (AOC) would elevate the response of OXN deposition to a 20 % abatement of emissions (expressed as the ratio of percentage change of deposition to emissions) from 82.6 % in the 2010s to nearly 100 % in the 2060s. In contrast, the response of reduced nitrogen (RDN) deposition to NH3 emissions would decline, likely attributable to a more NH3-rich condition. The outcomes of this work broaden scientific understanding on how anthropogenic actions of air quality improvement and carbon emission reduction would reshape future Nr deposition and support effective policymaking to reduce associated ecological damage.

Abstract. Aerosols play a critical role in the Arctic's radiative balance, influencing solar radiation and cloud formation. Limited observations in the central Arctic leave gaps in understanding aerosol dynamics year-round, affecting model predictions of climate-relevant aerosol properties. Here, we present the first annual high-time-resolution observations of submicron aerosol chemical composition in the central Arctic during the Arctic Ocean 2018 (AO2018) and the 2019–2020 Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expeditions. Seasonal variations in the aerosol mass concentrations and chemical composition in the central Arctic were found to be driven by typical Arctic seasonal regimes and resemble those of pan-Arctic land-based stations. Organic aerosols dominated the pristine summer, while anthropogenic sulfate prevailed in autumn and spring under haze conditions. Ammonium, which impacts aerosol acidity, was consistently less abundant, relative to sulfate, in the central Arctic compared to lower latitudes of the Arctic. Cyclonic (storm) activity was found to have a significant influence on aerosol variability by enhancing emissions from local sources and the transport of remote aerosol. Local wind-generated particles contributed up to 80 % (20 %) of the cloud condensation nuclei population in autumn (spring). While the analysis presented herein provides the current central Arctic aerosol baseline, which will serve to improve climate model predictions in the region, it also underscores the importance of integrating short-timescale processes, such as seasonal wind-driven aerosol sources from blowing snow and open leads/ocean in model simulations. This is particularly important, given the decline in mid-latitude anthropogenic emissions and the increase in local ones.

The paper presents an algorithm for the precipitation intensity estimation from the data of the MSU-GS spectroradiometer on board the Elektro-L No. 4 satellite. The algorithm is based on two neural networks with transformer and convolutional architectures and aimed at detection of precipitation-forming clouds and quantification of precipitation, respectively. The Global Precipitation Measurements (GPM) Integrated Multi-SatellitE Retrievals (IMERG) product is used as a reference source of information about precipitation intensity for training and testing the neural network models. The presented algorithm takes into account spectral, textural, and microphysical properties of clouds and allows obtaining precipitation maps for both daytime and nighttime conditions. The test results have shown an RMSE value of 1.27 mm/hour and F1 score of about 0.59 for the warm and cold seasons.

The predicted changes in timber storages and vegetation potential productivity in the taiga zone of European Russia in the 21st century is analyzed. The analysis is based on the ensemble climate change projections carried out with the MGO regional climate model and detailed calculations with the atmospheric boundary layer model. The return period of meteorological droughts in the middle and late 21st century is estimated, and the changes in the index characterizing moisture supply of plants during droughts are shown. It is demonstrated that the predicted changes in productivity and timber storages under climate warming, which are calculated based on future climate normals, can be refined by accounting for the intensity and frequency of droughts. The use of the correlation relationships describing the link between the climate normals of average annual temperature and precipitation and timber storages to estimate future timber storages by the end of the 21st century allows taking into account adverse effects of droughts and deficiency of available soil moisture on the state of plant communities.

Amplification of the surge fluctuations in the level of the Sea of Azov caused by the passage of deep small-scale cyclones is studied using the ADCIRC nonlinear longwave hydrodynamic model. The influence of the speed and direction of cyclone movement on the magnitude of surges is investigated for the following coastal settlements: Taganrog, Dolzhanskaya, Primorsko-Akhtarsk, Temryuk, Mysovoe, Genichesk, Berdyansk, and Mariupol. Three types of cyclones whose speeds varied within 3-20 m/s are considered: western, southwestern, and northwestern ones. It has been found that when western and southwestern cyclones pass over the sea, the strongest surges occur mainly when the speed of the cyclone approaches the resonant speed of free long waves in a part of the sea where a coastal settlement is located. The impact of northwestern cyclones on the sea leads to the excitation of the most intense surge oscillations at low cyclone speeds (V = 3 m/s) in most of the analyzed settlements. It is shown that consideration of the horizontal gradient of atmospheric pressure in the model can increase the magnitude of surges by 15%. Using atmospheric reanalysis data, the situations when real cyclones moved over the Sea of Azov were simulated. The simulations have shown that the approach of the cyclone speed to the resonant speed can lead to the amplification of surge fluctuations when cyclones move over the sea in the eastern and northeastern directions.

Based on ice maps of the Sea of Azov for 1993-2023 routinely compiled at the Hydrometcenter of Russia, nine winters with the most challenging ice conditions have been selected. For each of the winters, the features of ice formation, changes in ice characteristics, and possible reasons for the formation of challenging ice conditions are described. Data on the maximum thickness of fast ice in the winters under consideration from four hydrometeorological stations are presented, and a method for computing the spatial distribution of drifting ice thickness is proposed. By the example of the winter of 2016/2017, a change in ice thickness over time on the shipping route from the Taganrog Bay to the Kerch Strait is studied.
DIÁLOGO BILÍNGUE INTERCULTURAL BRASIL-MOÇAMBIQUE ENTRE ESTUDANTES SURDOS E OUVINTES NA PÓS-GRADUAÇÃO

Published: February 2025

As abordagens interculturais da linguagem trazem a sala de aula como um espaço intercultural que coloca em diálogo diferentes culturas relacionadas estruturalmente entre si, ou que deveriam estar, cabendo ao professor orientar e transformá-lo num espaço verdadeiramente intercultural, fazendo com que cada momento da aula se torne num momento de compartilhamento de saberes. O artigo aborda sobre o diálogo bilíngue intercultural Brasil-Moçambique entre estudantes surdos e ouvintes. O principal objetivo do estudo é conduzir para uma reflexão sobre a perspectiva intercultural na formação de professores de línguas usando a formação da educação linguística bilíngue em turmas com alunos surdos, em interação com ouvintes brasileiros, indígenas e não indígenas, e moçambicanos. A metodologia usada foi baseada no relato de experiência na disciplina de Aspectos Interculturais da Linguagem, oferecida no ano de 2022, no Programa de Pós-Graduação em Letras e Linguística da Universidade Federal de Goiás. Os fundamentos teóricos estão assentes em Mendes (2022), Rezende et al (2020), Strobel; Gesser (2009) e Aguiar (2010). A reflexão demonstra que é urgente uma Educação Linguística Intercultural que ressignifique a nossa existência e as nossas práticas como professores e/ou alunos. Tanto para o contexto do Brasil como de Moçambique, a educação de estudantes surdos não pode significar apenas a definição de propostas éticas, políticas educacionais em nível funcional, mas também no entendimento de que o corpo existe e resiste numa perspectiva intercultural.
ARA PYAU E AS SEMENTES SAGRADAS

Published: February 2025

Para os povos do campo e da floresta, as sementes são sagradas, no entanto as sementes nativas estão desaparecendo. Num movimento de resistência, literaturas indígenas têm revelado a importância de proteger a diversidade das sementes para garantir a segurança e soberania alimentar de suas comunidades, bem como para usufruir as políticas públicas educacionais do Programa Nacional de Alimentação Escolar. Os objetivos do artigo são levantar, discutir e analisar a diversidade das sementes do milho inscritas nas literaturas indígenas, entrecruzando-as com as possibilidades de ofertar na alimentação escolar o milho colorido ameríndio. Como metodologia, são analisadas as literaturas indígenas: Makunaimã taanii: presente de Makunaimã e O sopro da vida: Putakaryy kakykary do escritor indígena Kamuu Dan, do povo Wapichana. As sementes sagradas presentes nas literaturas indígenas motivaram a ação extensionista que culminou na organização e curadoria da exposição Ara Pyau (Tempo Novo).

O objetivo deste artigo é refletir acerca do conceito de quilombo e aquilombamento a partir dos escritos, vivências e memórias de Beatriz Nascimento (2021). Buscou-se relacionar o quilombo juntamente com a universidade, pois ambos se constituem como territórios de conexões e sobretudo da construção de práticas de ensino e aprendizagem. Esta pesquisa metodologicamente é de cunho qualitativo, de natureza aplicada e utilizou-se enquanto métodos a revisão bibliográfica, documental e a escrevivência de Conceição Evaristo (2017). Como principal arcabouço teórico, utilizamos dos escritos da autora Beatriz Nascimento (2021). Das conclusões possíveis, ressalta-se a importância de se trabalhar a história e cultura afro-brasileira e africana no Ensino Superior, oferecendo base para a prática de professores (as) por meio do currículo universitário. Essa ecologia de saberes (Santos, 2010) oportuniza diálogos entre ensino, pesquisa e extensão que dialogam nos espaços da escola, universidade e quilombo.
