The automotive remanufacturing industry is the largest remanufacturing sector, accounting for around two-thirds of global remanufacturing activities. Engine parts are a common target for remanufacturing due to their high value and demand. With the introduction of the National Automotive Policy (NAP) 2020 in Malaysia, many small and medium-sized enterprises (SME) are progressively taking part in the remanufacturing industry, especially engine remanufacturing. However, since the remanufacturing process is more complex than the primary production of the same products, challenges partaking in the operations and processes of remanufacturing are common in the industries, especially for independent remanufacturers. There still lacks data that shows the process flows of these engine-remanufactured products being conducted locally. In this study, a qualitative interview has been conducted through focus group discussion (FGD) with the SMEs to determine the processes and practices for automotive remanufacturing, thereby identifying key components of engine remanufacturing. Four different category questions, accompanied by several sub-questions to determine the processes and methods in their aspects of automotive remanufacturing, have been asked. The findings show that engine remanufacturing is a series of intricate processes being done carefully and extensively, from the cleaning process to the final assembly testing for which varies heavily depending on the components and industries. While the remanufacturing processes across the independent remanufacturers are almost the same, findings also suggest there exist additional processes that can be applied to increase the lifespan of the products, such as additive remanufacturing techniques, that these independent remanufacturers know but do not apply to their processes due to the cost and economics of the business. Further research exploring case studies of these independent remanufacturers is recommended to ensure a more holistic and critical aspects of engine remanufacturing to be captured.

Este artigo trata da história de uma erva indígena, a Ayapana, natural do vale amazônico e aclimatada em outras regiões do planeta. A trajetória dessa planta, sua circulação no interior da capitania do Grão-Pará até os círculos científicos europeus no século XVIII e XIX, nos mostra, em grande parte, como ocorreu o processo de apropriação dos saberes indígenas e como foram integrados ao que se considerava, na época, um conhecimento científico, que ao ser posto em trânsito por uma anônima índia acabou tomando rumos globais. O trabalho analisa a história desta planta indígena a partir dos sujeitos que tiveram contato com ela e isso permitiu mostrar como estavam inseridos em um universo de construção e apropriação de saberes locais e de circulação de conhecimentos que, como veremos, deixa em evidência uma ampla rede de contato que faz a ligação entre o império ultramarino português e seus agentes.

Acid sulfate soils (ASS) cause big problems worldwide due to their potential to form sulfuric acid during oxidation of sulfidic materials, resulting in very acid soil (pH <4.0). Impacts include acidification of soil and water, leaching of metals, decreased nutrient supply, deterioration of water fauna and flora, and corrosion of infrastructure. These soils also exhibit poor geotechnical properties. Finland has the largest occurrences of ASS in Europe, mainly along the coast of the Baltic Sea. The EU Water Framework Directive brought about wide co-operation to reduce the harmful impacts of ASS in Finland. One urgent step was to localize and characterize the occurrences of ASS. The more than 10 year-long programme, led by the Geological Survey of Finland (GTK), started in 2009 and field work was completed in 2021. During the programme observations, measurements, sampling and analyses were made at 23 000 sites in an area of 5 010 000 ha. Traditionally ASS in Finland have been considered to comprise fine-grained sulfidic sediments and/or their oxidized layers, occurring on agricultural land along the coast below the highest shoreline of the Littorina Sea transgression. This study recognized and classified significant occurrences of other types of potentially harmful ASS materials: (1) coarse-grained ASS (sand), (2) organic ASS (peat) and (3) unsorted ASS (till material). The methods, definition and classification of Finnish ASS have been revised. We calculated the extent of ASS along the coast to be about 1 000 000 ha corresponding to 21% of the area covered in the past by the Littorina Sea, and three to six times more than earlier estimates. In addition, some occurrences of ASS were recognized inland, mainly related to black shales and sulfidic ores. The mapping data can be accessed via the GTK map service (www.gtk.fi) providing information about the distribution and properties of ASS.

Toward a Metadata Standard for Distributed Acoustic Sensing (DAS) Data Collection
Authors: Lai Voon Hui , Hodgkinson Kathleen M. , Porritt Robert W. , Mellors Robert
Published: February 2024

With increasing geophysical applications using distributed acoustic sensing (DAS) technology, there is a need to implement a metadata standard specifically for DAS to facilitate the integration of DAS measurements across experiments and increase reusability. We propose a metadata standard intended primarily for the DAS research community, which fully describes the five key components of a DAS experiment: (1) interrogator; (2) data acquisition; (3) channels; (4) cable; and (5) fiber. The proposed metadata schema, which is the overall structure of the metadata, is hierarchical based, with a parent “overview” metadata block describing the experiment, and two main child branches describing the instrument (i.e., interrogator, photonics setup, and acquisition parameters) and the sensor locations (i.e., cable installation and fiber properties). The metadata schema is designed to be independent of the time-series data so that corrections and updates can be applied to the metadata without having to manipulate large volumes of time-series data. Unique identifiers are used as pointers that map different components within the metadata schema; they also provide a natural basis for the naming convention (i.e., source identifier) of the time-series data in which the time series can be described using identifiers defined by the metadata standard. We advocate for the metadata to be stored in a separate structure from the data itself. The metadata standard is successfully applied to four common scenarios: horizontal direct buried cable, dark fiber, borehole cable, and active survey, and two hypothetical scenarios: multiple interrogators to a single cable, and a single interrogator to multiple cables. Finally, we use GitHub to implement version control for the metadata standard, to enable community collaboration and facilitate sustainable development of the metadata standard, as the DAS technology and application continue to evolve.
Earthquake Disaster Fatality Data: Temporally Stable Power Law Behavior and Effects of Underreporting
Authors: Joshi Niranjan , Roberts Roland , Tryggvason Ari , Lund Björn
Published: February 2024

We investigate changes in the global reported fatalities from earthquake disasters in the global Emergency Events Database (EM-DAT). Drawing parallels with the Gutenberg–Richter frequency–magnitude analysis, in terms of disaster frequency versus the number of casualties, we see a significant overlap of the curves and improving levels of completeness over six 20-year periods. This implies a decrease in underreporting with time. We find that the apparent strong upward trend in the number of (reported) earthquake disasters in EM-DAT is caused by a gradually improved reporting primarily of events killing fewer than 10 people. Our findings imply that the true (reported and unreported) number of earthquake disasters, according to the EM-DAT definition, has been surprisingly constant over, at least, the last 100 yr. We also show that the average annual number of people killed in earthquake disasters is relatively unaffected by spurious trends in reporting and has remained remarkably constant despite population increase. This implies an impressive reduced mortality risk roughly proportional to population increase since 1900. However, there is no indication in the data that the risk of future mega-disasters is negligible, and further major reductions in vulnerability should be actively pursued.
Are endodontically treated abutments more successful than vital tooth abutments in FPD? Systematic review and meta-analysis
Authors: Susila Anand
Published: February 2024

AIM: Intentional Root canal treatment of abutments is preferred by many prosthodontists to satisfy the principles of parallelism and line of draw before construction of fixed partial dentures. However, intact non-supra-erupted and non-tilted teeth need not be devitalized as this weakens the abutment. Hence this systematic review was undertaken to understand if the success of fixed partial denture improves with devitalized abutments. MATERIALS AND METHODS: The systematic review was done according to the PRISMA guidelines 2020. The databases searched were PubMed, Cochrane and Google Scholar. New castle Ottava scale of risk of bias tool was used for assessing the bias. Certainty of evidence was assessed using GRADEpro. Studies eligible for Meta-analysis was evaluated using Forest plot. RESULTS: 11 studies were selected for the systematic review. None of the studies found non vital abutments to be superior to vital abutments in the survival or longevity of FPDs. All the studies included in the review either concluded that vital abutments improved the longevity/survival of FPDs and decrease the risk of complications or that there was no significant difference between vital and non-vital abutments for the success of FPDs. Meta-analysis was done for 8 eligible studies using Forest plot. CONCLUSION: Endodontically treated abutments are not favorable for the longevity/survival of FPDs with less risk of hazards/complications. Therefore, vitality of the abutment should not be sacrificed unless there is a questionable pulpal and/or periapical diagnosis preoperatively.

Published: February 2024

Background: Lifestyle Medicine (LM) is an emerging field that can enable providers to educate patients on the impact of their health behaviors. Therefore, LM is emerging as an important component of medical education. But studies investigating the effects of LM education in medical students are sparse. Aims: This paper reports on a controlled study to test the effects of a lifestyle medicine education elective within the medical school curriculum. Methods: The study was IRB approved. Fifty-eight preclinical students gave informed consent. Students completed screening instruments which assessed physical activity, consumption of fats and fruits/vegetables, anxiety, perceived distress, and mood. First-year students were assigned to the control group and were reassessed after three months. Second-year students chose one of three focus groups (nutrition, stress management or physical activity) and set a personal goal for change. Each focus group met a minimum of three times. At the end of the intervention, they were reassessed. The controls had the opportunity to participate in the same focus groups for the same amount of time. Statistical analysis comprised analysis of covariance and paired t-tests. Results: Intervention students performed better than the controls in reducing perceived stress, anxiety, and dietary fat. Paired t-tests comparing baseline and post intervention in all subjects who had the intervention revealed significant improvements in perceived stress, anxiety, mood, dietary fat, fruits and vegetables consumption and number of minutes of physical activity. Analysis of the focus groups pre and post measures showed significant improvements in anxiety and perceived stress in the stress management groups, improvements in both measures of nutrition, but no significant changes in physical activity. Conclusion: It is feasible to add LM concepts and techniques to the medical school curriculum. Medical students significantly improved multiple lifestyle medicine behaviors after being part of the elective. They also experienced the process of setting SMART goals and implementing a plan for change, which can be useful in their future practice.

Published: February 2024

Background: The liver possesses remarkable regenerative abilities following parenchymal injury. This study aimed to assess and document the microscopic regenerative changes in the rat liver using a partial hepatectomy model. Methodology: Adult male Sprague Dawley rats weighing approximately 200-300 grams were subjected to partial hepatectomy, leaving approximately 70% future liver remnant. The rats were euthanized at designated time intervals (1/2 hour, 48 hours, 72 hours, 7 days, 11 days, and 14 days) for histological analysis of the liver. Results: Liver regeneration was observed within 1 week of partial hepatectomy. Cytoplasmic vacuolization increased until day 7, but decreased significantly during the regenerative process. Disruption of cytoplasmic membranes and blurring of cell-to-cell and cell-to-sinusoidal space boundaries decreased notably from day 11. Necrosis involving central veins and portal tracts was observed on the first day after hepatectomy. By day 7, the portal tract exhibited granulomatous inflammation with conglomerates of epithelioid macrophages forming giant cells. The sinusoidal spaces displayed increased lymphocyte volume on day 7. Patchy portal inflammation consisting of lymphocytes, plasma cells, occasional eosinophils, and monocytes was observed from day 7 post-hepatectomy. Conclusion: In this partial hepatectomy animal model, the inflammatory cascade was evident through confluent necrosis affecting approximately 10% of the hepatic parenchyma, along with subcapsular infarction. Cytoplasmic vacuolization affected approximately 50% of the cells. The study documented various histological changes during the post-hepatectomy period, demonstrating the initiation of hepatocyte regeneration within one week.
UNDERSTANDING THE DYNAMICS OF COVID-19 TRANSMISSION IN PAMPANGA PHILIPPINES: MODELING WITH A SYSTEM OF DIFFERENTIAL EQUATIONS
Authors: Mendoza Aldrin
Published: February 2024

This study introduced and solved a system of differential equations aimed at modeling the coronavirus disease 2019 (COVID-19) transmission dynamics in the province of Pampanga. Specifically, a Susceptible, Infected, Recovered, Deceased (SIRD) model was developed and built upon the foundational SIR model devised by Kermack and McKendrick in 1927.1 Various methods were employed to solve the model. Initially, the analytical solution for the rate of change of infected individuals over time was determined. Subsequently, model parameters were identified through an optimization process using the Microsoft Excel Solver. The Runge-Kutta fourth order (RK4) method, implemented in Scilab 6.1.1, was utilized to approximate the numerical solution for the rates of change of susceptible , recovered , and deceased over time. The findings underscored the significance of several parameters—namely, the transmission rate , removal rate (combining recovery and deceased rate ), the proportion of the infected population properly wearing face masks , the proportion disinfecting regularly , and the proportion practicing isolation or social distancing —in shaping the transmission dynamics of COVID-19 in Pampanga. The values of these model parameters reflect the effectiveness of governmental responses and actions in managing, controlling, and mitigating the spread of COVID-19, as well as the extent of public cooperation and compliance with COVID-19 directives and advisories.
Deep Learning-Based SC-FDMA Channel Equalization

Published: February 2024

It is very challenging to design an effective wireless communication system. That’s because of numerous factors affecting the performance of a typical wireless communication system, such as nonlinear channel distortions and impairments. single carrier frequency division multiple access (SC-FDMA) is a multiple access scheme that is an important part of the long-term evolution (LTE) standard for uplink transmission. An advanced mobile radio system’s multiple access schemes should indeed meet stringent requirements, such as a low bit error rate (BER). In this article, we investigate the equalization problem for nonlinear channel distortions and impairments using deep neural networks (NN). We introduce a novel combined deep neural network channel equalization and symbol detection scheme based on a deep learning (DL) recurrent feedback (RF) long short-term memory (LSTM) neural network to achieve blind equalization and decoding for SC-FDMA systems without knowing the channel state information (CSI). To train the model efficiently, the training data is gathered by simulation, with channel effects and noise treated as a complete black box. CSI and constellation demapping are learned by a deep neural network (DNN) model. Then, the frequency-domain sequences that have been corrupted are implicitly equalized to get the broadcasted signal back. Our specified SC-FDMA system, which uses a quadrature phase-shift keying (QPSK) modulation method and the suggested Deep Learning-based model channel equalizer, performs better than the existing equalizers by an average of 1 to 4 dB at moderate signal-to-noise (SNR) ratios, according to simulation data. A complexity comparison between the proposed and the conventional equalizers was conducted in terms of training time, execution time, and number of operations. On combined channel equalization and symbol detection, the suggested system delivers state-of-the-art performance.
Re-Evaluating the SPRT Chart with Estimated Process Parameters When the Underlying Distributions Are Gamma, Lognormal, and Weibull
Authors:   School of Mathematical and Computer Sciences, Heriot-Watt University Malaysia, Putrajaya, Malaysia, Teoh Wei Lin
Published: February 2024

To reduce the impact of Phase-I parameter estimation on the performances of Phase-II control charts, researchers have incorporated the ideology of Guaranteed In-control Performance (GICP) in their statistical designs to limit the risk of excessive false alarms. At present, most research works have primarily focused on normally distributed data. However, the assumption of normality is often violated in manufacturing environments, and certain data may exhibit positively skewed distributions. In this paper, we investigate the performance of the SPRT control chart with estimated process parameters designed using the GICP method under three different skewed distributions, i.e., the Gamma, Lognormal, and Weibull distributions. The study is conducted by varying the Phase-I sample size and the degree of skewness in order to reveal their impacts upon the in-control and out-of-control performances of the SPRT chart with estimated process parameters. Results show that an increase in the skewness level leads to rapid deterioration in both the in-control and out-of-control expected values of the average time to signal (AATS) and the average standard deviation of the time to signal (ASDTS). Interestingly, we have found that increasing the Phase-I sample size leads to deterioration in the conditional in-control performance, but an improvement in the out-of-control AATS and ASDTS values. Furthermore, it is found that, among the three distributions, the Lognormal distribution produces the least stable performance when skewness is large and the Phase-I sample size is small.

Published: February 2024

Wilt caused by Fusarium oxysporum f. sp. ciceris (Padwick) is an important soil-borne disease and considered as most serious and widespread disease of chickpea throughout the world. Twenty indigenous isolates of Trichoderma spp. were isolated from the rhizosphere of chickpea in different geographic regions of Karnataka. Among twenty isolates, a higher concentration of volatile compounds was produced by TR-14 (72.22%) followed by TR-19 (66.67%) and TR-9 (65.93%). Further, the efficient strain that is TR-14 was identified as Trichoderma asperellum molecularly and was used to extract metabolites by using solvent extraction technique and subjected to GC-MS/MS analysis. The results have shown presence of twenty-nine compounds at different retention times ranging from 4.910 to 21.868 min. and the mass-to-charge (m/z) ratio from 43 to 190. Out of twenty-nine compounds, the concentration of 2-Imidazol-1-ylmethyl-pyridine 1-oxide (C9H9N3O) was highest with the maximum area (14375440) and retention time (19.842). Apart from this compound, 7-Isopropylidene-5-methyl-2, 3-diazabicyclo (2.2.1) hept-5-ene-2,3 dicarboxylic acid, diethyl ester was present at the highest peak with a retention time of 20.021.

Alternaria alternata wreaks havoc on fruit and vegetable production globally, threatening food security by causing black leaf spot disease. Bacillus subtilis, a natural inhabitant of soil, is a promising biological control agent for the management of A. alternata. In the present study, the antagonistic potential of B. subtilis NBAIR-BSWG1 was initially confirmed against A. alternata through a dual culture technique with 43.03% inhibition of mycelial growth. Subsequently, we extracted the cell-free extract from the NBAIR-BSWG1 pure culture and assessed its impact on A. alternata through the poison food technique and found mycelial growth inhibition of 85.82%. Identification of secondary metabolites biosynthetic genes using specific PCR markers showed the presence of surfactin genes (sfp, srf AA) with an amplicon size of 675 bp and 201 bp, respectively. Amplification of fengycin (fenB) and iturin (ituD) at 670 bp and 423 bp respectively, by using a specific PCR primer confirms the contribution of fengycin and iturin for the antagonistic potential of NBAIR-BSWG1. This study identifies NBAIR-BSWG1 as an effective bacterial biocontrol agent for control of A. alternata, unlocks the genetic basis of antifungal activity NBAIR-BSWG1, depicts molecular mechanisms involved in biological suppression of A. alternata by NBAIR-BSWG1 paving the way for the development of bioformulations for management of A. alternata.
Decentering the Human through Narrative Forms

Decentrare l’umano tramite forme narrative. La ‘chiusura impossibile’ del Pasticciaccio di Gadda e della Trilogia dell’Area X di VanderMeer
Il presente articolo si pone l’obiettivo di individuare ed esaminare le caratteristiche narrative formali capaci di suggerire una concezione di vita come intricata matassa di incontri e relazioni fra esseri umani e non umani. Partendo dal presupposto che le innovazioni formali moderniste abbiano anticipato le narrative postumane contemporanee, l’articolo offre una comparazione neo-formalista fra Quer pasticciaccio brutto della via Merulana (1957) di Carlo Emilio Gadda e La trilogia dell’Area X (Annientamento, Autorità, Accettazione, 2015) di Jeff VanderMeer. In entrambe le opere sono identificabili due caratteristiche peculiari: la prima consiste in una comune impronta autoriale che segue un principio di accumulamento e complicazione manifestantesi in un accavallarsi di teorie non soddisfacenti e spesso incomplete, ma che comunque cercano di dare una soluzione o spiegazione ai misteri al centro dei rispettivi testi. La seconda corrisponde all’affidamento della narrazione ad una moltitudine di personaggi che si rivelano sempre parziali in quanto inabili a comprendere i fenomeni accaduti nella loro interezza. Infatti, i testi analizzati riescono a ridimensionare l’eccezionalità umana dimostrando che la realtà è sempre più complessa ed intrecciata di quanto sia umanamente comprensibile. Da questo ridimensionamento consegue l’impossibilità ad avere una conclusione che si possa definire finale.

La sardina crinuda azul (Opisthonema bulleri) es parte de los desembarques comerciales de peces pelágicos menores del sur del Golfo de California; la pesquería está certificada como sostenible por Marine Stewardship Council. Los parámetros de crecimiento de esta especie son de gran interés en la evaluación y manejo de la pesquería del complejo Opisthonema. En este estudio, se generó un conjunto de datos de edad a la talla de 367 lecturas de otolitos de los años 2005 y 2015 para completar los meses del año calendario con información continua e inferir la periodicidad de formación de la marca de crecimiento. Se utilizó un enfoque de selección multimodelo en cinco submodelos especiales del modelo de Schnute generalizado, incluido uno equivalente al modelo de von Bertalanffy. El tipo de borde mensual de los otolitos sugiere una marca de crecimiento anual. Se identificaron seis grupos de edad (0-5 años), con una APE y CV de 4,5 y 2,9 % respectivamente. El análisis de edad a la talla del conjunto de datos con la selección multimodelo es una garantía de que el caso uno de Schnute es el mejor para describir y estimar los parámetros de crecimiento de O. bulleri del sur del Golfo de California.

Los exopolisacáridos (EPS) pueden ser utilizados como agentes reductores confiriendo mejores propiedades físicas y químicas a las nanopartículas metálicas. Este estudio tuvo como objetivo sintetizar y evaluar las características fisicoquímicas, estructurales y funcionales de nanopartículas de ZnO producidas con EPS de Lactiplantibacillus fabifermentans BAL-27-ITTG. La caracterización estructural de los EPS exhibió una estructura de alto peso molecular compuesta principalmente de manosa y glucosa con enlaces α-1,4, α-1,3, α-1,6 de acuerdo al espectro de RMN. El aumento de la concentración de EPS en la síntesis provoca el incremento en el tamaño de las partículas en escala micrométrica disminuyendo el índice de polidispersidad. La síntesis de las nanopartículas se confirmó mediante un barrido espectral UV-vis y el espectro FT-IR mostró picos de absorción a 600 cm-1 asociados al enlace Zn-O. Las nano y micropartículas sintetizadas mostraron actividades funcionales mejoradas respecto al EPS libre. Los valores máximos en actividad antioxidante (80.25 %), capacidad de retención de agua (3.06 g H2O/g muestra), actividad emulsionante (69.85%) y actividad floculante (69.07 %) se obtuvieron con las MpZnO-EPS sintetizadas con 6 mg/mL del agente reductor. Se observó actividad bacteriostática contra Staphylococcus aureus y L. fabifermentans. El ensayo de biocompatibilidad confirmó la obtención de partículas no hemolíticas.

Pure polyacrylonitrile (PAN) fibers with diameter size at micrometric scale were obtained and collected radially using an immersion-jet wet spinning .system. This technique is a fast and easy approach to fabricate micrometric PAN fibers. The diameter of the fiber can be easily controlled by adjusting the size of the spinneret. Uniform, smooth and continuous PAN microfibers were suitable modified by thermal stabilization and alkaline saponification to obtain pH-sensitive fibers. The effect of diameter size fiber on the chemical actuation behavior was investigated in terms of length change characteristics under the influence of pH solution. The microfibers showed expanding/contracting behavior and force generation stimulated by changes in the environment pH. The fibers structural and chemical properties were characterized using the FT-IR spectroscopy and SEM microscopy techniques.
Contact Tracing Applications in the Context of COVID-19 Pandemic: Proposals for Acceptance of its Use

Published: February 2024

COVID-19 has been the biggest threat humanity has faced since World War II. The rapidity of its spread generated a general feeling of uncertainty and fear. National governments had to adopt measures in a context of total ignorance of the threat. The development of contact tracing applications has emerged as the fastest option to contain the spread of the virus. However, its acceptance has been reduced. This study intends to understand the reasons for the resistance in the use of those applications and to identify proposals so that in future situations the use of applications of contact tracing can be generalized. This is a qualitative study using a literature review in accordance with the procedures. The literature review allowed us to identify, on the one hand, three dimensions in the approach to the theme: technical, legal, and political. In the particular case of COVID-19, the political dimension stood out compared to the others.
A Critical Study of Matthew 18:15-18 in New Testament Greek and Selected Akan Mother-Tongue Translations: Implication for Peace-Making in Ghana
Authors: Asamoah Emmanuel Foster , Kpalam Ebenezer Tetteh
Published: February 2024

Recent global research reveals a world characterised by increasing fragmentation, diminished peace, and mounting risks for future generations. Diverse conflicts, ranging from familial to national issues, persist, even among individuals sharing the same faith. In Africa, nations like Cote d’Ivoire, the Democratic Republic of Congo, Burundi, Rwanda, the Central African Republic, and Sierra Leone grapple with severe consequences of conflicts. In Ghana, pockets of ethnic discord impact education, healthcare, and social services, prompting the emigration of skilled professionals. Despite ongoing peace efforts in Ghana, effective approaches are crucial. With over 70% of Ghanaians identifying as Christians, contextualising peace-making within sacred texts becomes imperative. In this exploration, the study delves into a biblical approach, specifically scrutinising Matthew 18:15–18 through exegetical analysis in Greek language and mother-tongue hermeneutics. These approaches reveal a convergence between the biblical author’s original meaning conveyed in the Greek language and its interpretation in the mother tongue. The paper advocates private conflict resolution to avoid gossip, involving witnesses if needed and church leaders if the issue persists. Disciplinary measures may be necessary, emphasising personal dignity and adherence to God’s will. The paper significantly contributes to conflict resolution knowledge, providing valuable insights for fostering peace in Ghana and beyond.

Published: February 2024

Dans le district de Bamako, les cours d’eau sont le milieu récepteur privilégié des rejets des activités de teinture. Ces rejets, non traités sont source de problèmes environnementaux et sanitaires. L’objectif de cette étude est d’analyser les effets environnementaux et sanitaires de la teinture artisanale à Dianéguela en commune VI du district de Bamako. La méthodologie s’est appuyée sur l’observation directe, les enquêtes et l’analyse de certains paramètres qualitatifs de l’eau usée de teinture et des eaux de la rivière de Dianéguela. Par rapport à la turbidité, les résultats font ressortir respectivement 109 UNT pour le point A, 47 UNT pour le point B et 5 UNT pour le point C. La DBO, la DCO, l’oxygène dissous, la couleur, le pH, les orthophosphates, l’arsenic et la conductivité analysés ne répondent pas aux normes maliennes de rejet, ni à la grille d’évaluation relative aux eaux de surface de bonne qualité. Les effets sont la dégradation de la qualité des eaux de la rivière de Dianéguela avec une incidence négative sur l’environnement biophysique et la santé humaine ainsi que les nuisances olfactives. La gestion durable des effluents de teinture à Dianéguela nécessite la réhabilitation du centre de teinturerie, le traitement des eaux par une station d’épuration, la sensibilisation des teinturières, l’application rigoureuse de la règlementation.

 

In the Bamako district, waterways are the preferred receptors for waste from dyeing activities. These untreated discharges are a source of environmental and health problems. This study aims to analyze the environmental and health effects of artisanal dyeing in Dianéguela in municipality VI of the Bamako district. The methodology was based on direct observation, surveys, and analysis of qualitative parameters of the dyeing wastewater and the waters of the Dianéguela river. Regarding turbidity, the results show 109 NTU for point A, 47 NTU for point B, and 5 NTU for point C, respectively. The BOD, COD, dissolved oxygen, color, pH, orthophosphates, arsenic and conductivity analyzed do not meet Malian discharge standards, nor the evaluation grid for good quality surface water. The effects are degradation of water quality in the Dianéguela river, with a negative impact on the biophysical environment and human health, as well as odor nuisance. Sustainable management of dyeing effluents in Dianéguela requires rehabilitation of the dyeing center, water treatment by a wastewater treatment plant, awareness-raising among dyers, and rigorous enforcement of regulations.
