Authors: Nurhidayah Muhammad Gading , Jumiarni Dewi , Yennita Yennita
Published: November 2024

The electronik modul (e-module) is a digital learning resource designed to enhance the educational experience. However, at SMA 06 Seluma, there is a noticeable lack of electronic teaching materials, particularly those based on local environmental content, like biodiversity. This study aims to develop a biodiversity e-module that draws from the surrounding environment. The development process followed the 4-D model, which includes four stages: defining, designing, developing, and disseminating. The research involved interviews and observations of medicinal plants. The findings identified 37 species of medicinal plants across 22 families utilized by the Bali tribe in Tawang Rejo Village. Validation results for the e-module were positive: content experts rated it 92% "highly suitable," media experts rated it 97.9% "highly suitable," and practical experts gave it a 94.3% "highly suitable" rating. Additionally, the readability test with students from class X Science 1 at SMA 6 Seluma resulted in a 97% "excellent" rating. These outcomes suggest that the medicinal plant biodiversity e-module is a valuable and effective supplementary learning tool for students.

Published: November 2024

Phytopathogenic fungi are the main limitations in the development and productivity of forest species. The objective of this research was to identify the phytopathogenic microorganisms associated with leaf spots of forest species located on the premises of the Faculty of Agrarian Sciences of the National University of Asunción, Paraguay. Individuals of each species that present leaves with initial symptoms were randomly selected, collecting two leaves for each symptom and placing them in airtight bags. For the isolation and identification of fungi, the samples obtained were processed in the following ways: direct and indirect assembly (sowing in Potato Dextrose Agar culture medium). The phytopathogenic fungi were identified thanks to their morphological characters such as: colony texture and coloration, somatic structures and spores. Some phytopathogenic species have been identified: Powdery mildew in Handroanthus hepthaphyllus, Algal spot - Cephaleuros virescens Kunze in Eugenia uniflora, Rust in Handroanthus impetiginosus - Prospodium bicolor, Tar spot - Apiosphaeria guaranitica in Handroanthus albus, Coleosporium plumeriae rust in Plumeria rubra and Phyllachora balansa and in Cedrela fissilis. It is concluded that with the identification of phytopathogenic microorganisms associated with native forest species there is the opportunity to detect sources of infection and thereby establish sanitary actions for a future management program.
Comunidade microbiana do solo e podridão radicular em meloeiro em diferentes sistemas de manejo
Authors:   , Nascimento Paula Gracielly Morais Lima do
Published: November 2024

O presente trabalho teve como objetivo quantificar a comunidade microbiana do solo cultivado com meloeiro e avaliar a incidência de podridão radicular no meloeiro, nos sistemas de plantio direto (PD) e convencional (PC) associado à coberturas do solo. Dois experimentos (dois ciclos do meloeiro) foram conduzidos em área naturalmente infestada com patógenos habitantes do solo. A incidência de podridão radicular foi avaliada nos dois ciclos, enquanto a quantificação da comunidade microbiana do solo apenas no primeiro ciclo. O experimento foi conduzido na fazenda Agrícola Famosa entre os municípios de Tibau-RN e Icapuí-CE, no Nordeste do Brasil. O delineamento experimental foi o de blocos casualisados, no esquema de parcelas subdivididas. Nas parcelas foram avaliados dois sistemas de plantio com e sem revolvimento do solo (PC e PD) e nas sub-parcelas, sete coberturas de solo (Crotalária; Milheto; Consórcio crotalária + milheto; Consórcio milho + braquiária; Vegetação espontânea; Vegetação espontânea + filme de polietileno; Solo sem vegetação). Os materiais foram dessecados e, incorporados ao solo, no plantio convencional enquanto no plantio direto, foram mantidos sobre o solo. Foram realizadas seis coletas do solo (Área em pousio; Implantação dos adubos verdes; Transplantio do meloeiro e, aos 20, 40 e 60 dias após o transplantio-DAT), em cada subparcela, para quantificação de Bacillus spp. , Pseudomonas fluorescens, bactérias totais e fungos totais. Para a quantificação de microrganismos, utilizou-se o método de diluição seriada e plaqueamento em meio de cultura específico para cada grupo analisado. Após a colheita dos frutos todas as plantas de meloeiro das subparcelas foram coletadas, lavadas e analisadas quanto à presença de podridão radicular. A comunidade microbiana do solo (Bacillus spp. ,Pseudomonas fluorescens bactérias totais e fungos totais) variou em função dos sistemas de plantio (direto ou convencional) nas diferentes épocas de coleta de amostras no ciclo do meloeiro. O cultivo da crotalária associada ao plantio direto do meloeiro causou maior quantidade de UFCs de bactérias totais em relação ao plantio convencional. Os sistemas de plantio e as coberturas do solo não alteraram a quantidade de fungos totais e Pseudomonas fluorescens. A comunidade microbiana do solo cultivado com meloeiro é influenciada pelo sistema de plantio e de cobertura do solo. A incidência da podridão radicular no meloeiro foi menor no sistema de plantio direto pré-cultivado com crotalária, milheto, ou vegetação espontânea. Fusarium solani, Macrophomina phaseolina, Monosporascus cannonballus e Rhizoctonia solani foram os patógenos que ocorreram no meloeiro, sendo o primeiro fungo, o de maior ocorrência em ambos os sistemas de plantio. A incidência de podridão radicular do meloeiro é dependente do sistema de cultivo e de plantio
Inteligência artificial e rizomas da ação comunicativa na ágora digital
Authors: Brennand Edna Gusmão de Góes , Dutra Delamar José Volpato
Published: November 2024

O texto busca discutir paradoxos do debate público na era da Inteligência Artificial. Parte da concepção de esfera pública de Habermas e sua aplicabilidade no seio das reflexões atuais sobre o debate público e suas novas modalidades potencializadas pelas tecnologias digitais. Pretende trazer ao escrutínio das reflexões as formas de como jovens adultos de diferentes países garantem sua participação na esfera pública digital através do exercício da cidadania, da consolidação de uma sociedade bem-informada e coautora de seus sistemas político e jurídico. Na configuração da ágora digital, o uso da inteligência artificial em diferentes enquadramentos sociais e políticos originam diferentes níveis de participação, uma vez que estamos situados em três domínios de fronteiras difusas: Mundo analógico (cidadãos desconectados) Mundo digital (cidadãos conectados) e Mundo híbrido (cidadãos e máquinas conectados).  Se, conforme argumenta Habermas, a vida em sociedade não é possível sem a comunicação e a relação com o outro, como garantir diálogo e consenso no mundo híbrido? Como pensar a democracia no cyberespaço e em uma esfera pública, que agregue vontades, argumentos, posições, defesas e consensos?
A questão algorítmica
Authors: Lemos Grayce , Espíndola Marina Bazzo de
Published: November 2024

Este artigo explora os desafios impostos pela implementação de sistemas algorítmicos e inteligência artificial (IA) em diversas plataformas que fazem parte da cultura digital hoje. O foco principal é analisar como a literatura científica recente relaciona a questão algorítmica com os fenômenos da pós-verdade e a crise da democracia, em um contexto onde a disseminação de fake news e a manipulação digital desempenham papeis centrais. A pesquisa mapeia artigos publicados nos últimos dois anos, pós-pandemia, identificando correlações entre a aparição do termo ‘pós-verdade’, o declínio da confiança social nas instituições democráticas e o colapso da verdade na esfera pública, o que tem configurado um cenário chamado de ‘crise da democracia’. Entre os temas abordados nos 13 artigos analisados, destacam-se a relação entre democracia e fake news, a crise da verdade na esfera pública e a manipulação algorítmica na era digital. Com base nesses estudos, o artigo esboça os desafios para a consolidação de uma política pública informada e democrática em um cenário cada vez mais influenciado por algoritmos e plataformas digitais. Em última análise, o trabalho contribui para a compreensão dos impactos das novas tecnologias na democracia, propondo caminhos possíveis para mitigar os riscos da pós-verdade e fortalecer o espaço público democrático.

Criptoanálise
Authors: Preger Guilherme de Figueiredo
Published: November 2024

Este artigo apresenta uma revisão do conceito de Inteligência Artificial pela ótica da transformação digital, que é, alegadamente, uma transformação dos meios de produção. Esta transformação acaba por confundir o terreno da produção, local histórico da análise marxista, com o da reprodução social, levando a uma expansão do campo de análise social para além das fronteiras econômicas tradicionais. É observado que a plataformização é a arquitetura hegemônica que acomoda a transformação digital. Ela amplia o cercamento dos bens comuns próprio ao sistema capitalista acrescentando uma mercadoria fictícia, a informação, às demais já presentes (terra, trabalho, dinheiro). Cria-se mais uma camada de regime de acumulação, que denomino de “espetacularização”.  Como modelo para esta abordagem, é sugerido o método estratégico da criptoanálise que se estabelece pelo tratamento da distinção transparência/opacidade, proposta pelo sociólogo Niklas Luhmann.  Observa-se que esta é a distinção que rege o princípio da complexidade. Com isso, é possível rastrear os danos gerados pelos usos indiscriminados da Inteligência Artificial generativa, que estão latentes (ocultos) na adoção da tecnologia. O artigo finaliza com uma reflexão sobre o alcance do arcabouço legal e regulatório que está sendo pensado no Brasil para esta nova tecnologia.
Lidocaine Induces Neurotoxicity by Activating the CaMKII and p38
MAPK Signaling Pathways through an Increase in Intracellular Calcium
Ions
Authors: Ma Qian , Wang Meng , Zhang Bin , Jia Danting , Chen Xuexin
Published: November 2024

Background:

Lidocaine is extensively utilized as an anesthetic in clinical settings; however,
it has demonstrated significant neurotoxicity when administered for spinal anesthesia. The specific
mechanisms underlying lidocaine-induced neurotoxicity are poorly understood.

Objective:

This study aimed to investigate the mechanisms through which lidocaine induces neurotoxicity,
focusing on its effects on intracellular calcium release and the activation of CaMKⅡ and
MAPKs pathways, as well as to evaluate the potential protective effects of cilnidipine.

Methods:

The investigation has employed both in vitro cell models and in vivo mouse models to
conduct the experiments. Neuronal cell viability has been assessed following lidocaine treatment,
and neurological function has been evaluated in mice after intrathecal injection of lidocaine. Intracellular
calcium levels, CaMKⅡ activation, and the phosphorylation of p38 and p65 have been measured
in cultured hippocampal neuronal cells and mouse brain tissues. The effects of the calcium
channel blocker cilnidipine on these parameters have also been examined.

Results:

Lidocaine treatment led to a reduction in cell viability in cultured neuronal cells and induced
neurological dysfunction in mice. It increased intracellular Ca2+ levels and activated CaMKⅡ
in both cultured neuronal cells and mouse brain tissues. Lidocaine also elevated the phosphorylation
levels of p38 and p65 in neuronal cells. These effects have been suppressed by cilnidipine, indicating
a calcium-dependent mechanism.

Conclusion:

This study suggests that lidocaine induces neurotoxicity through a calcium-dependent
activation of CaMKⅡ and MAPK pathways, leading to neuronal apoptosis and dysfunction.
Cilnidipine has been found to exhibit promise as a protective agent against lidocaine-induced neurotoxicity.
The Role of Peer Relationships in Problematic Internet Use among Adolescents: A Scoping Review and Meta-analysis
Authors: Andrianie Prilya Shanty , Japar Muhammad , Pratisti Wiwien Dinar , Kasturi Taufik , Purwandari Eny
Published: November 2024

Background

The swift advancement of technology, particularly the internet, has significantly influenced various aspects of human life, resulting in both positive and negative consequences. In Indonesia, adolescents represent the largest group of internet users, with usage durations exceeding four hours per day, making them vulnerable to issues such as Problematic Internet Use (PIU). During adolescence, peer relationships play a crucial role in social development.

Objective

This study aims to explore how peer relations can influence problematic internet use among adolescents and identify strategic factors that contribute to reducing PIU based on systematic review findings. Additionally, the research seeks to quantify the relationship between peer relations and problematic internet use among adolescents through meta-analysis. The hypothesis posits a correlation between peer relations and problematic internet use among adolescents.

Methods

The research employs scoping review and meta-analysis techniques.

Results

Scoping review results indicate that, overall, peer relationships can have both positive and negative impacts on PIU. A more positive relationship between adolescents and their peers tends to correlate with lower levels of PIU. Conversely, adolescents with problematic peer relationships are more likely to develop PIU behaviours. Meta-analysis results further strengthen these findings, demonstrating a significant correlation between peer relationships and problematic internet use among adolescents (r = 0.191; p = 0.020; 95% CI).

Conclusion

Despite the significant correlation, the influence of peer relationships on problematic internet use appears to be relatively low. This suggests the existence of other factors that contribute to PIU behaviours beyond peer relationships.

Authors: Abiri Elaheh , Raesi Rasoul , Kashani Maryam Haji Ghasem
Published: November 2024

Background

Suicide is a crisis, and its occurrence in healthcare workers (HCWs) is a special challenge that requires urgent interventions.

Aim

This study was conducted to determine the effectiveness of the health promotion lifestyle training program on suicidal thoughts in HCWs.

Methods

This one-sample longitudinal study was conducted using a multi-stage sampling method on 248 healthcare providers in 2023. In the first stage, the Beck scale was used to measure suicidal thoughts, and the DASS-21 was used to measure depression, anxiety, and stress. In the second stage, individuals with suicidal thoughts were placed in a separate group, and educational intervention continued for them. The health promotion lifestyle training protocol was provided to this group as a training program, and researchers followed up on its implementation for 95 days. In the third stage, after the completion of the educational intervention, the Beck scale and DASS-21 were once again provided to the target group. Data were analyzed in SPSS-25 statistical software.

Results

27.8% of participants had suicidal thoughts, 7.66% represented high-risk suicidal ideation, and 20.1% had low-risk suicidal ideation. 69 HCWs who had suicidal thoughts used the Health-Promoting Lifestyle Education Program for 95 days. The percentage of suicidal thoughts in people with high suicidal risk ideation decreased from 7.66% to 4.03% (p<0.05), and in people with low-risk suicidal ideation decreased from 20.1% to 13.30% (p<0.05).

Conclusion

Health promotion educational programs can be used as an effective intervention in improving mental health indicators and reducing suicidal thoughts in HCWs.

Published: November 2024

Background

Rear-end crashes on toll roads have been a significant issue in Indonesia. This type of crash exists and needs a mitigation strategy. However, limited research exists examining the mechanism and contributing factors of these crashes in Indonesia. This research aimed to describe how rear-end crashes have occurred on toll roads in Indonesia, describe associated risk factors, develop a model for assessing the risk of rear-end crashes on Indonesian toll roads and identify potential mitigation strategies.

Materials and Methods

A questionnaire was developed and assessed for validity and reliability. It was distributed (online) to 220 drivers who had experienced a rear-end crash or near-crash in the past year.

Results

The findings from this study showed that contributing factors are driver (55%), environment (33%), and vehicle (12%). Subject vehicles usually consisted of private vehicles, while the lead (struck) vehicles included private vehicles (91.8%), trucks (7.27%), and buses (0.93%).

Discussion

This study also found two phenomena of local unique behavior in Indonesian toll roads that lead to rear-end crashes, such as “Lane Hogger” and driving under the speed limit (trucks) that lead other vehicles to rear-end crashes.

Conclusion

Factors contributing to rear-crash risk on Indonesian toll roads were driving experience (ownership driving license 15-20 years), breaking driving rules, driving in the right lane, and using an MPV. The findings from this study can improve potential mitigation strategies, including developing focused driving rules, traffic signs on toll roads, and crash avoidance technology.

Introduction: Multiple sclerosis (MS) is a chronic autoimmune, demyelinating, and neurodegenerative disease of the central nervous system, the relapsing-remitting (RRMS) form affects around 85% of patients at the beginning. While current disease-modifying therapies (DMTs) reduce relapses and slow disability progression, they have significant side effects and do not promote neural repair. Umbilical cord-derived mesenchymal stem cells (UCMSC) offer potential for immunomodulation, neuroprotection, and repair in MS without the intensive immunoablation required for autologous hematopoietic stem cell transplantation (AHSCT).

Methods: This single center, randomized, double-blind, crossover phase IIa trial will evaluate the safety and feasibility of intravenous UCMSC administration in active RRMS patients. Participants will receive either UCMSC or placebo in a 1:1 ratio, with a crossover to the alternate treatment after 24 weeks. Primary outcomes include safety, measured by adverse events, and feasibility, assessed through recruitment, retention, and dropout rates. Secondary outcomes involve clinical and paraclinical indicators, including disability, quality of life, fatigue, mood disorders, and inflammation markers.

Discussion: This trial aims to address the safety and feasibility of UCMSCs in RRMS. If both aspects are corroborated, and a trend of efficacy is noted in the exploratory outcomes, then a larger study is warranted to further explore this therapeutic option with fewer side effects and potential for enhanced neuroprotection and repair. Successful results may also lead to broader applications in other autoimmune and neurodegenerative diseases, fostering interdisciplinary collaboration and advancing MS research and treatment.

Conclusion: This exploratory phase IIa study will provide valuable insights into the safety and feasibility of UCMSC in treating RRMS, highlighting the need for further research to optimize dosing and administration routes, and confirming efficacy in larger, more diverse populations.
The Role of Film Festivals in Promoting Social Justice: Authorship, Disruption, and Innovation at the CineMigrante Film Festival (Buenos Aires, Argentina)
Authors: Peralta García Lidia , Simour Lhoussain
Published: November 2024

This paper revolves around Migration Film Festivals as a rich and interdisciplinary fertile subject of inquiry and analysis at an international scale. Its primary aim is to conduct an in-depth analysis of CineMigrante, Festival de Cine y Formación en Derechos Humanos (CineMigrante, Film Festival and Training in Human Rights), held in Buenos Aires (Argentina) since 2010. It serves as an invaluable case study for the understanding of the significance of film festivals in advancing social justice, cultivating community involvement, and championing migrant rights. Its pioneering methods and influence render it a crucial blueprint for analogous endeavors globally. The theoretical framework focuses on the concept of authorship to highlight how social innovation has a lot to do with the creativity and disruptive capacity of a film festival. A comprehensive mix of quantitative and qualitative methodologies is employed, encompassing formal content analysis of the festival catalog and detailed examination of the structural, visual, and para-visual elements present on the festival’s website, media platforms, and textual materials. The study variables under consideration include curation criteria, programming activities, interactions with the media and local community organizations, corporate image, and communication strategies. Results show that CineMigrante’s social success is based on its disruptive and innovative dynamics to reach audiences, challenge narratives, and act as a catalyst for social transformation.
Zonas Cinzentas e Ângulos Mortos: Reflexões em Torno da Produção de Conhecimento nos Estudos Sobre Migrações Portuguesas
Authors: Azevedo Liliana
Published: November 2024

No contexto português, a figura de “o emigrante” tem persistido ao longo do tempo e permeado as representações mediáticas, os discursos políticos e as produções científicas. A sociologia das migrações tem produzido numerosos textos sobre “emigração” e “regresso”, no entanto, são escassas as reflexões sobre as condições de produção do conhecimento. Este texto pretende contribuir para uma reflexão crítica sobre as categorias utilizadas na investigação produzida em Portugal. Partindo de um conjunto de questionamentos epistemológicos decorrentes do trabalho etnográfico que desenvolvi durante as pesquisas de doutoramento (2018–2022) e pós-doutoramento (2023–2024), reflito sobre um conjunto de zonas cinzentas e ângulos mortos nos estudos sobre migrações portuguesas intraeuropeias. Neste artigo, discuto nomeadamente o uso das noções de “emigrante”, “idade”, “percurso de vida”, “género” e “etnicidade”, apelando a uma abordagem reflexiva da chamada “emigração portuguesa” e, mais amplamente, do processo de produção do conhecimento. Esta reflexão reveste particular importância na medida em que certas categorias se revelam demasiado rígidas para dar conta dos atuais padrões de circulação, bem como da fluidez que carateriza as vivências de pessoas com experiências e/ou origens migratórias.
Collaborative reading and foreign language learning with literature
Authors: Matiola Vanessa
Published: November 2024

Teletandem is a virtual exchange context designed by Telles and Vassallo (2006), in which two learners of different foreign languages meet in video conferencing platforms so that one helps the other in their learning process. These meetings are divided in two parts, each of them focused on the use of one of the languages, so that both have the opportunity to practice their target language. Since 2019, a thematic teletandem has been carried out so that participants do tasks related to the discussion of literary texts, which was named Literatandem. In this practice report, an interaction will be presented, in which two partners discussed a Literatandem activity to demonstrate how sharing interpretations of a literary text can expand the understanding of a text in a foreign language. As a result, it was noted that the tasks incited participants to exchange prior knowledge and negotiate meaning, which expanded the way they perceived language and allowed them to have new interpretations of the texts.

Published: November 2024

Unmanned Aerial Vehicle (UAV) remote sensing is recommended to evaluate damage quickly and quantitatively. Therefore, this study aimed to explore the use of RGB aerial images by UAV for evaluating drought damage of rice through canopy color and coverage. The procedures were conducted in the dry season of 2018 (August – September 2018) at the Balitkabi Experimental field, Muneng, Probolinggo, Indonesia. A split-plot experimental field design was used with 2 factors, namely drought treatments at growth stage (Vegetative/P1, Reproductive/ P2, Generative/P3, and Control/P0), and varieties (Jatiluhur/V1, IPB9G/V2, IPB 3S/V3, Hipa 19/V4, Inpari-17/ V5, Mekongga/V6, Mentik Wangi/V7, Ciherang/V8). Canopy temperature data were then obtained using FLUKE 574 Infrared Thermometer, while images were taken with an RGB camera (Zenmuse X5) attached to Drone DJI Inspire I. The images were taken twice during the treatment (4 DAT and 15 DAT), followed by analysis using QGIS 2.18 and ImageJ. The results showed that RGB aerial images by UAV could be used in agricultural insurance in Indonesia, and similar countries around the world. Although the effect on yield needed to be evaluated, quick assessment by UAV was still an effective tool. In addition, drought damage evaluation through canopy color was better than canopy coverage in terms of analysis. The conversion from RGB to Lab color space increased the determination coefficient in multiple regression of color values against temperature difference (Tc-Ta).
Major Fisheries Species along with Their Contribution to the National Fishery Production in Bangladesh
Authors: Manik Mehedi Hasan
Published: November 2024

In Bangladesh, due to its geographical location, fisheries play a significant role in socioeconomic development and food security. The country has 57 major rivers and nearly 118,813 km2 marine area in the Bay of Bengal. Almost 260 freshwater and 740 marine water fisheries species are found in Bangladesh. There is a lack of studies dealing with species-wise production status and growth rate in Bangladesh. This study is conducted to discover the recent trend of fisheries yield with major species-wise production share and growth rate. The required data have been collected from the website of the Department of Fisheries of the government of Bangladesh. Fisheries yield is increasing in Bangladesh, but the inland culture segment is growing fast compared to inland capture and marine segments as the slope of inland culture is 1.1, higher than inland capture and marine. Species converging in the major carp group are the highest, over 21%, contributor to the national yield. As a single species, the Hilsa takes the maximum production share, around 12%. The contribution of marine species is poor, approximately 15% of the total yield, compared to the potential. Bangladesh may raise the required export diversification based on fisheries resources. To do so, the policymakers of Bangladesh should raise funds for blue economic research, human resource development, and technology import.

Published: November 2024

The striped snakehead (Channa striata Bloch, 1793) is a freshwater fish which has long been popular as a food fish. Commonly found in freshwater bodies such as rivers, swamps and lakes, striped snakeheads have a high albumin protein content which can help to accelerate wound healing, facilitate the circulation of body fluids and maintain osmotic pressure in the body. Salinity is one of the limiting factors that can affect fish growth and survival. Changes in salinity could directly affect striped snakehead growth and metabolism. The purpose of this study was to determine the effect of different salinity treatments on the growth and albumin content of juvenile striped snakeheads. The research was conducted in November-December 2021 at the Water Quality and Aquatic Biology Laboratory, Faculty of Animal Husbandry and Fisheries, Tadulako University, Indonesia. The study applied 5 salinity treatments (2 ppt, 4 ppt, 6 ppt, 8 ppt and 10 ppt) with 8 replicates for 30 days. Net weight gain, specific growth rate (weight and length) and survival rate did not differ significantly between treatments (ANOVA, P>0.05). The Tukey post-hoc test indicated significantly higher growth under the 8 ppt salinity treatment (1.04±0,19 cm) with 100% survival rate. Albumin content increased linearly with salinity from 2 ppt (3.6-4.0%) to 10 ppt (4.9-5.3 %).

Debido al proceso de despoblamiento del pastal de Mulluri, la mayoría de las prácticas vinculadas al pastoreo ya no se realizan, siendo muy escaso el ganado que hoy pastea en el territorio. Sin embargo, el conocimiento asociado (lo técnico, social, geográfico) se encuentra resguardado en las memorias individuales y colectivas, particularmente de las personas de mayor edad que se criaron pasteando llamos y alpacos en el pastal. Por ello, gran parte del registro obtenido proviene de entrevistas y talleres, aunque también hubo instancias fundamentales de observación participante. En relación con estas últimas, compartimos durante el ciclo anual del año 2016 en dos ocasiones con el comunero Ángel García, quien todavía realiza la trashumancia con ganado ovino hacia la costa. Primero lo encontramos en la paskana de Caritaya (mayo) y luego en la paskana Macusa (septiembre), esta última ubicada en el pastal de Parcohaylla. Este trabajo también permitió realizar un mapeo y calendarización del circuito que realizó don Ángel García durante el mencionado año.
Etnopercepción: Las regiones geográficas desde el pastal
Authors: García-Barriga Magdalena
Published: November 2024

Para describir el territorio de Mulluri, los comuneros ocupan la noción de “arriba” para referirse al espacio de mayor altitud o porción oriental del pastal, y “abajo” para hacer referencia al espacio de menor altitud o lado poniente. En cierto modo, “arriba” y “abajo” son equivalentes a los espacios o pisos ecológicos, a los que se refieren como “cordillera” y “costa”, respectivamente (ver Figura 2). Junto a estos, los comuneros reconocen un tercer espacio geográfico o piso ecológico fuera de los deslindes del territorio, correspondiente al “valle”.

Authors: Azócar-Duarte Rodrigo , Milin Théo
Published: November 2024

Lithium mining has engaged in different types of relations with Indigenous communities since arriving in the Salar de Atacama between the 1980s and 1990s. One such relations strategy, Corporate Social Responsibility (CSR), was deployed in several regions worldwide in the 1990s as a joint effort by the mining industry to improve its image and focus on the episteme of ‘sustainable mining.’ This research looks at Ayllu Wine and the Toconao Harvest Festival, organized by the winemakers’ cooperative and SQM, to analyze CSR in relation to the concepts of extractivism and ritual. On the basis of qualitative research using ethnographies, interviews, press archive reviews and secondary sources, this paper concludes that, in the midst of the current lithium boom, the Harvest Festival is, in spatial and temporal terms, a SQM governability strategy that produces tension in the community. Behind the festivity, discourse and iconography of ‘responsible mining’ lies booming extractivist production.

Several reports on genome sequencing using Next Generation Sequencing (NGS) to identify the total genome were extensively carried out; however, genome identification on thermophilic microorganisms is still limited. In this report, genome identification of thermophilic microorganisms isolated from compost, namely Pseudoxanthomonas taiwanensis AL17, was carried out. The result showed that AL17 contains 3,064,463 bp with a GC content of 72.08%. The genome comprises 2,833 CDSs, 6 RNA (5S, 16S, and 23S), 48 tRNA genes, and 17 Pseudogenes. A comparison of the genome to data based on Average Nucleotide Identity from Dfast-qc shows that the genome is closely related to Pseudoxanthomonas taiwanensis. Further analysis discovers numerous genes coding for potential enzymes, including hydratase, transferase, dehydrogenase, exopeptidase and hydrolases. In addition, the genome exhibits a number of stress-tolerant genes. Detailed analysis of the hydrolase genes, especially for esterase and lipase, showed that the genome exhibits no true lipase but a lipolytic enzyme within the GDSL-type esterase/lipase motif. The genomic information provides an understanding of thermophilic genomes and their relevance to stress-tolerant adaptation and explores potential genes, especially for industrial applications.

The present study was aimed to evaluate five different microbial consortia for rapid composting of paddy straw and analyze the quality of compost produced. The experimental study on rapid composting of paddy straw was taken at ICAR-NBAIM, Kushmaur, Mau, Uttar Pradesh, India, during the period February to April 2022. The paddy straw was collected from the farm of ICAR-IISS, Mau, U.P., India and the collected paddy straw was chopped into 4-5 cm and further used for the study. The composting experiment was performed in bio-conversion bags of size [12 (L) x 4 (B) x 3 (H) feet]. There were six treatments in which five treatments were taken to evaluate five different microbial consortia and one control (no microbial consortium added). The five different microbial consortia tested were BIO-FAST, BIO-COMPOST, NCOF, PUSA and TEJAS. The results showed that Carbon-Nitrogen (C:N) ratio was reached to less than 20 at 60 days in BIO-FAST applied paddy straw followed by NCOF. While, the C:N ratio of control at 60 days was 33.71. Similarly, the primary nutrients (N, P and K) were higher (p < 0.05) in BIO-FAST followed by NCOF applied compost. The microbial activity and enzymatic activities were found to be insignificant (p < 0.05) in microbial consortia added treatments. The diluted extract of compost (50% and 20%) had higher germination index and no phytotoxicity effect. Thus, the results revealed that the addition of BIO-FAST accelerate the composting process and produce quality compost from paddy straw in 60 days.

The World Health Organization documented 247 million reported malaria cases worldwide resulting in 619,000 fatalities in 2021. More than 70% of these deaths are attributed to Children under five years of age and sub-Saharan Africa is the region in which the highest number of deaths occur. The Plasmodium falciparum parasite is the deadliest form of malaria, and treating falciparum infection is becoming more challenging due to the emergence of drug-resistant parasites, causing a decrease in the efficiency of antimalarial medications. Artemisinin combination therapy is now considered the gold standard for malaria treatment; however, this method is at risk due to parasites exhibiting delayed clearance to artemisinin and resistance to partner drugs such as lumefantrine, amodiaquine, mefloquine, piperaquine, and sulfadoxine/pyrimethamine. This review assessed drug targets in Plasmodium falciparum for the development of novel antimalarials. Over Eighty-five papers on malaria, Plasmodium falciparum protein targets, and protein inhibitors were gathered from Google Scholar, ProQuest, PubMed, and Science Direct, between 2012 and 2023. Only articles with comparable keywords on malaria drug targets concentrating on enzyme proteins, carrier molecules present in Plasmodium falciparum, and their inhibitors were retrieved for review, while articles within that range that did not provide definite data were excluded. Most recently, inhibitors of dihydroorotate dehydrogenase (DHODH), artefenomel (OZ439), and ferroquine have been reported and are being explored in combination with other partner medications to work against different stages of plasmodium parasite. In identifying target proteins for drug development, essentiality and vulnerability throughout the life cycle of the parasite, its druggability, and the availability of target-based assays are critical factors. The use of modern proteomics and cellular proteins from database search which assists in parasite proliferation delivers optimal information on the new generation of lead compounds. In addition, advances in in silico methods enable the identification of protein targets for drug development.

The global challenge of antibiotic resistance among gastrointestinal pathogens is increasing daily. Gastroenteritis is a major health challenge in developing countries and is ranked 8th among the top 10 causes of death in Namibia. While medicinal plants used in Namibia could be the source of medicine for gastroenteritis, there is a gap in knowledge regarding the efficacy and safety of most medicinal plants used in Namibia. The study aimed to evaluate the antibacterial and cytotoxicity of medicinal plants used in Namibia to manage gastroenteritis. Aqueous and methanol extracts were prepared from Lantana camara, Grewia tenax, Corchorus tridens, Albizia anthelmintic, and Terminalia sericea. Agar disc diffusion and resazurin-based microtiter dilution assay were used to determine the antibacterial activity. Antibiogram assay was used to determine the susceptibility of gastrointestinal pathogens to 11 clinically used antibiotics. Normal mouse embryo fibroblast cells using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay were used for the cytotoxicity test. A 70% multidrug resistance to ampicillin, cephalosporin, sulphamethoxazole, erythromycin, penicillin, vancomycin, and ampicillin was observed among clinical isolates of Salmonella and Escherichia coli. Meanwhile, L. camara methanol seed extracts showed potent antibacterial activity against clinical strains of E. coli and Salmonella spp. (20.67 ± 1.53 and 21.67 ± 0.58 mm, respectively), with MICs between 31.25 and 62.5 µg/mL. The IC50 of all extracts was ≥65.85.00 ± 0.58 µg/mL. The study showed that methanol extracts of L. camara, C. tridens, and T. sericea have potent antibacterial activity against multidrug-resistant clinical Salmonella and E. coli. Moreover, methanol extracts did not show significant toxicity to NIH/3T3 cells.

Abstract: In this fast growing world, the usage of electrical appliances and gadgets has increased due to which the electricity
consumption has increased. Being caught in this busy life, people tend to forget things like switching off the electronic devices
after usage. This would cause a lot of electricity wastage. If a person recollects that some device is not shut off he needs to leave
his current work and reach the device to turn it off manually. This would cause a lot of energy and time wastage.
This proposes and analyze a system which is used for energy consumption and monitoring. The system is fully Internet of Things
(IoT) based and highly desirable in field of energy. In this system consumer can do power management by knowing energy
usage time to time. As the advancement of technology and dependencies over the electrical appliances increased, the usage and
requirement of electricity is also increased rapidly. Hence there is a need to reduce the wastage of electricity.
The smart laboratory system using IoT helps in monitoring the power consumption regularly. This also helps in controlling
various appliances used in the laboratory. This smart system will be helpful in generating the real-time data of the electricity
usage. Users will be able to see their daily usage from a web app with the help of their unique identification number and
password provided to them at the time of installation of this device. The objective is to make a novel system which will help in
reducing the usage and wastage of electricity.
