voltammetric method based on poly(diphenylamine-4-sulfonic acid) modified glassy carbon electrode (poly(DPASA)/GCE) was developed for determination of gallic acid. Appearance of an irreversible oxidative peak at both bare GCE and poly(DPASA)/GCE for gallic acid with about three folds current enhancement and much reduced potential at poly(DPASA)/GCE showed catalytic property of the modifier towards oxidation of gallic acid. Under optimized conditions, Adsorptive stripping square wave voltammetric peak current response of the poly(DPASA)/GCE showed linear dependence with gallic acid concentration in the range 5.00 × 10-7 − 3.00 × 10-4 mol L-1 with limit of detection of 4.35 × 10-9. Spike recovery results between 94.62-99.63, 95.00-99.80 and 97.25-103.20% of gallic acid in honey, raw peanut, and commercial peanut butter samples respectively, interference recovery results with less than 4.11% error in the presence of uric acid and ascorbic acid, lower LOD and relatively wider dynamic range than most of the previously reported methods validated the potential applicability of the method based on poly(DPASA)/GCE for determination of gallic acid real samples including in honey and peanut samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gallic%20acid" title="gallic acid">gallic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=diphenyl%20amine%20sulfonic%20acid" title=" diphenyl amine sulfonic acid"> diphenyl amine sulfonic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorptive%20anodic%20striping%20square%20wave%20voltammetry" title=" adsorptive anodic striping square wave voltammetry"> adsorptive anodic striping square wave voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a>, <a href="https://publications.waset.org/abstracts/search?q=peanut" title=" peanut"> peanut</a> </p> <a href="https://publications.waset.org/abstracts/172221/poly-diphenylamine-4-sulfonic-acid-modified-glassy-carbon-electrode-for-voltammetric-determination-of-gallic-acid-in-honey-and-peanut-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172221.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> The Tragedy of Colonialism in Non-colonised Society: Italy’s Historical Narratives and the Amhara Genocide in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Birhanu%20Bitew%20Geremew">Birhanu Bitew Geremew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In its attempt to colonize Ethiopia, Italy challenged the nationalism of Ethiopiawinet, claiming that Ethiopia is a mere collection of discrete ethnic groups brought together by Amhara colonialism. Extracting data from a variety of sources including secondary materials, opinions expressed in the broadcast, print and social media platforms, party documents, official letters and key informant interviews, this paper provides a critical reflection on how the colonial presence of Italy made a political mess in Ethiopia by asserting ethnic nationalism. The paper argues that the narratives invented by the Italians greatly contributed to the emergence of ethnic nationalism following the advent of Marxism-Leninism in Ethiopia. Borrowing narratives from the Italians, Ethiopian ethnic elites of the 1960s, who were the advocates of Marxism, simplistically categorized the Amhara as oppressor while ‘others’ as oppressed in Leninist fashion. This categorization negatively shaped the attitude of ‘others’ towards the Amhara and instigated massively executed genocide against these people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amhara%20colonialism" title="Amhara colonialism">Amhara colonialism</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=Genocide" title=" Genocide"> Genocide</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20narratives" title=" historical narratives"> historical narratives</a>, <a href="https://publications.waset.org/abstracts/search?q=Marxism" title=" Marxism"> Marxism</a> </p> <a href="https://publications.waset.org/abstracts/146341/the-tragedy-of-colonialism-in-non-colonised-society-italys-historical-narratives-and-the-amhara-genocide-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Hate Speech Detection Using Machine Learning: A Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edemealem%20Desalegn%20Kingawa">Edemealem Desalegn Kingawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kafte%20Tasew%20Timkete"> Kafte Tasew Timkete</a>, <a href="https://publications.waset.org/abstracts/search?q=Mekashaw%20Girmaw%20Abebe"> Mekashaw Girmaw Abebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Terefe%20Feyisa"> Terefe Feyisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Abiyot%20Bitew%20Mihretie"> Abiyot Bitew Mihretie</a>, <a href="https://publications.waset.org/abstracts/search?q=Senait%20Teklemarkos%20Haile"> Senait Teklemarkos Haile</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, hate speech is a growing challenge for society, individuals, policymakers, and researchers, as social media platforms make it easy to anonymously create and grow online friends and followers and provide an online forum for debate about specific issues of community life, culture, politics, and others. Despite this, research on identifying and detecting hate speech is not satisfactory performance, and this is why future research on this issue is constantly called for. This paper provides a systematic review of the literature in this field, with a focus on approaches like word embedding techniques, machine learning, deep learning technologies, hate speech terminology, and other state-of-the-art technologies with challenges. In this paper, we have made a systematic review of the last six years of literature from Research Gate and Google Scholar. Furthermore, limitations, along with algorithm selection and use challenges, data collection, and cleaning challenges, and future research directions, are discussed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amharic%20hate%20speech" title="Amharic hate speech">Amharic hate speech</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning%20approach" title=" deep learning approach"> deep learning approach</a>, <a href="https://publications.waset.org/abstracts/search?q=hate%20speech%20detection%20review" title=" hate speech detection review"> hate speech detection review</a>, <a href="https://publications.waset.org/abstracts/search?q=Afaan%20Oromo%20hate%20speech%20detection" title=" Afaan Oromo hate speech detection"> Afaan Oromo hate speech detection</a> </p> <a href="https://publications.waset.org/abstracts/163615/hate-speech-detection-using-machine-learning-a-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163615.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Using Machine Learning to Enhance Win Ratio for College Ice Hockey Teams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadixa%20Sanjel">Sadixa Sanjel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Sadek"> Ahmed Sadek</a>, <a href="https://publications.waset.org/abstracts/search?q=Naseef%20Mansoor"> Naseef Mansoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Denekew"> Zelalem Denekew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Collegiate ice hockey (NCAA) sports analytics is different from the national level hockey (NHL).

In the past, there were many projects that done to improve production of meat, milk and productivity of sheep breed. However, no significance research has been done so far on production of wool fiber in Ethiopia which could be taken as a potential fiber next to cotton. The measurement of the sheep wool fiber physical properties is critically important, technical, commercial and certification point of view. A total of 24 sheep from different breeds (Menz, Tikur, Farta and Washera) were used in this study. Samples of fiber were analyzed using standard measurements for wool fiber length (WFL), mean fiber diameter (MFD), coefficient of variation of wool fiber diameter (FDCV), breaking strength, elongation, crimp, cleanness and moisture content. Based on the result all parameters shows that there is a great potential of getting of wool fiber from the skin of sheep and according to the standards of its property and grading system based on wool fiber fineness is medium to course. These types of fibers can be making carpets, blankets, rugs, coverings and other products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fiber" title="Fiber">Fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=Fineness" title=" Fineness"> Fineness</a>, <a href="https://publications.waset.org/abstracts/search?q=Carpet" title=" Carpet"> Carpet</a>, <a href="https://publications.waset.org/abstracts/search?q=Fleece" title=" Fleece"> Fleece</a>, <a href="https://publications.waset.org/abstracts/search?q=Raw%20Wool" title=" Raw Wool"> Raw Wool</a> </p> <a href="https://publications.waset.org/abstracts/119161/characterization-of-the-physical-properties-of-sheep-wool-fiber-in-amhara-national-regional-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Pollution Challenges in the Akaki Catchment, Upper Awash Basin, Ethiopia: Potential Health Implications for Vegetables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minbale%20Aschale">Minbale Aschale</a>, <a href="https://publications.waset.org/abstracts/search?q=Bitew%20K.%20Dessie"> Bitew K.

It receives various pollutants from its catchments. The study aimed to assess the impact of wastewater irrigation on vegetables and inform stakeholders about pollution challenges and consequences. Eighty-two composite samples of matured vegetables were randomly collected from twenty-one agricultural farm sites. These samples were analyzed for potentially toxic elements, including Cd, Pb, Cr, Hg, As, Ni, Sr, B, Co, Cu, Mn, Fe, Zn, and Se. The results indicated significant variations in concentrations across different sites, with localized contributions from various contaminants. Cr, Cd, and Pb concentrations in most vegetables exceeded recommended levels. Pollution levels varied with metals and vegetable types. Different vegetables contribute differently to health risks. The relative contributions of Ethiopian kale, cabbage, red beet, lettuce, Swiss chard, Gurage cabbage, tomato, zucchini, carrot, onion, watermelon, and potato to the aggregated risk were 12.69%, 12.25%, 11.83%, 11.20%, 10.21%, 9.91%, 8.49%, 5.66%, 3.96%, 3.35%, 3.10%, and 2.72%, respectively. Comparison with permissible standards revealed inadequate environmental management by relevant regulatory bodies and industries. Despite good laws and standards at the federal and regional levels, they are ineffectively implemented or enforced to prevent environmental pollution. Mitigation measures are urgently recommended to address the potential health implications of toxic substances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pollution" title="pollution">pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20Awash%20Basin" title=" upper Awash Basin"> upper Awash Basin</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20risk" title=" health risk"> health risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/183333/pollution-challenges-in-the-akaki-catchment-upper-awash-basin-ethiopia-potential-health-implications-for-vegetables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">51</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Multi-Spectral Deep Learning Models for Forest Fire Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Smitha%20Haridasan">Smitha Haridasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Demissie"> Zelalem Demissie</a>, <a href="https://publications.waset.org/abstracts/search?q=Atri%20Dutta"> Atri Dutta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajita%20Rattani"> Ajita Rattani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aided by the wind, all it takes is one ember and a few minutes to create a wildfire. Wildfires are growing in frequency and size due to climate change. Wildfires and its consequences are one of the major environmental concerns. Every year, millions of hectares of forests are destroyed over the world, causing mass destruction and human casualties. Thus early detection of wildfire becomes a critical component to mitigate this threat. Many computer vision-based techniques have been proposed for the early detection of forest fire using video surveillance. Several computer vision-based methods have been proposed to predict and detect forest fires at various spectrums, namely, RGB, HSV, and YCbCr. The aim of this paper is to propose a multi-spectral deep learning model that combines information from different spectrums at intermediate layers for accurate fire detection. A heterogeneous dataset assembled from publicly available datasets is used for model training and evaluation in this study. The experimental results show that multi-spectral deep learning models could obtain an improvement of about 4.68 % over those based on a single spectrum for fire detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20fire%20detection" title=" forest fire detection"> forest fire detection</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-spectral%20learning" title=" multi-spectral learning"> multi-spectral learning</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20hazard%20detection" title=" natural hazard detection"> natural hazard detection</a> </p> <a href="https://publications.waset.org/abstracts/146865/multi-spectral-deep-learning-models-for-forest-fire-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146865.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">241</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Examining Ethiopian Banking Industry in Relation to Factors Affecting Profitability: From 2008 to 2012</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Zerihun">Zelalem Zerihun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, attempts were made to assess the bank-specific, industry-specific, and macro-economic factors affecting bank profitability. Data were collected from ten commercial banks in Ethiopia, covering the period of 2008-2012. A mixed method research approach was adopted for this research. Documentary analysis and in-depth interview were also used to substantiate the data. The study found out that capital strength, income diversification, bank size and gross domestic product are statistically significant and they have a positive relationship with banks’ profitability. However, operational efficiency and asset quality have a negative relationship with banks’ profitability. The relationship for liquidity risk, concentration and inflation were found to be statistically insignificant. The study revealed that focusing and reengineering the banks in light of the key internal drivers could enhance the profitability as well as the performance of the commercial banks in Ethiopia. In addition to this, the study suggests that banks in Ethiopia should not only be concerned about internal structures but also they must consider both the internal environment and the macro-economic environment in designing strategies to improve their profit or their performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ethiopian%20banking%20industry" title="Ethiopian banking industry">Ethiopian banking industry</a>, <a href="https://publications.waset.org/abstracts/search?q=macro-economic%20factors" title=" macro-economic factors"> macro-economic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=documentary%20analysis" title=" documentary analysis"> documentary analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20strength" title=" capital strength"> capital strength</a>, <a href="https://publications.waset.org/abstracts/search?q=income%20diversification" title=" income diversification"> income diversification</a> </p> <a href="https://publications.waset.org/abstracts/48548/examining-ethiopian-banking-industry-in-relation-to-factors-affecting-profitability-from-2008-to-2012" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48548.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Innovative In-Service Training Approach to Strengthen Health Care Human Resources and Scale-Up Detection of Mycobacterium tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsegahun%20Manyazewal">Tsegahun Manyazewal</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Marinucci"> Francesco Marinucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Belay"> Getachew Belay</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Tesfaye"> Abraham Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonfa%20Ayana"> Gonfa Ayana</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaha%20Kebede"> Amaha Kebede</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegahun%20Manyazewal"> Tsegahun Manyazewal</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Marinucci"> Francesco Marinucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Belay"> Getachew Belay</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Tesfaye"> Abraham Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonfa%20Ayana"> Gonfa Ayana</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaha%20Kebede"> Amaha Kebede</a>, <a href="https://publications.waset.org/abstracts/search?q=Yewondwossen%20Tadesse"> Yewondwossen Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Susan%20Lehman"> Susan Lehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Temesgen"> Zelalem Temesgen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In-service health trainings in Sub-Saharan Africa are mostly content-centered with higher disconnection with the real practice in the facility. This study intended to evaluate in-service training approach aimed to strengthen health care human resources. A combined web-based and face-to-face training was designed and piloted in Ethiopia with the diagnosis of tuberculosis. During the first part, which lasted 43 days, trainees accessed web-based material and read without leaving their work; while the second part comprised a one-day hands-on evaluation. Trainee’s competency was measured using multiple-choice questions, written-assignments, exercises and hands-on evaluation. Of 108 participants invited, 81 (75%) attended the course and 71 (88%) of them successfully completed. Of those completed, 73 (90%) scored a grade from A to C. The approach was effective to transfer knowledge and turn it into practical skills. In-service health training should transform from a passive one-time-event to a continuous behavioral change of participants and improvements on their actual work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title="Ethiopia">Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20care" title=" health care"> health care</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title=" Mycobacterium tuberculosis"> Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a> </p> <a href="https://publications.waset.org/abstracts/13878/innovative-in-service-training-approach-to-strengthen-health-care-human-resources-and-scale-up-detection-of-mycobacterium-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13878.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">504</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Field-Free Orbital Hall Current-Induced Deterministic Switching in the MO/Co₇₁Gd₂₉/Ru Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Abebe%20Bekele">Zelalem Abebe Bekele</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun%20Lei"> Kun Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiukai%20Lan"> Xiukai Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiangyu%20Liu"> Xiangyu Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Wen"> Hui Wen</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaiyou%20Wang"> Kaiyou Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spin-polarized currents offer an efficient means of manipulating the magnetization of a ferromagnetic layer for big data and neuromorphic computing. Research has shown that the orbital Hall effect (OHE) can produce orbital currents, potentially surpassing the counter spin currents induced by the spin Hall effect. However, it’s essential to note that orbital currents alone cannot exert torque directly on a ferromagnetic layer, necessitating a conversion process from orbital to spin currents. Here, we present an efficient method for achieving perpendicularly magnetized spin-orbit torque (SOT) switching by harnessing the localized orbital Hall current generated from a Mo layer within a Mo/CoGd device. Our investigation reveals a remarkable enhancement in the interface-induced planar Hall effect (PHE) within the Mo/CoGd bilayer, resulting in the generation of a z-polarized planar current for manipulating the magnetization of CoGd layer without the need for an in-plane magnetic field. Furthermore, the Mo layer induces out-of-plane orbital current, boosting the in-plane and out-of-plane spin polarization by converting the orbital current into spin current within the dual-property CoGd layer. At the optimal Mo layer thickness, a low critical magnetization switching current density of 2.51×10⁶ A cm⁻² is achieved. This breakthrough opens avenues for all-electrical control energy-efficient magnetization switching through orbital current, advancing the field of spin-orbitronics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spin-orbit%20torque" title="spin-orbit torque">spin-orbit torque</a>, <a href="https://publications.waset.org/abstracts/search?q=orbital%20hall%20effect" title=" orbital hall effect"> orbital hall effect</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20hall%20current" title=" spin hall current"> spin hall current</a>, <a href="https://publications.waset.org/abstracts/search?q=orbital%20hall%20current" title=" orbital hall current"> orbital hall current</a>, <a href="https://publications.waset.org/abstracts/search?q=interface-generated%20planar%20hall%20current" title=" interface-generated planar hall current"> interface-generated planar hall current</a>, <a href="https://publications.waset.org/abstracts/search?q=anisotropic%20magnetoresistance" title=" anisotropic magnetoresistance"> anisotropic magnetoresistance</a> </p> <a href="https://publications.waset.org/abstracts/182198/field-free-orbital-hall-current-induced-deterministic-switching-in-the-moco71gd29ru-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182198.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">55</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Lived Experience of Risk and Protective Contexts of Blind Successful University Students in Sidist Kilo Campus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Markos%20Borko">Zelalem Markos Borko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of life of people with blindness is significantly influenced by the level of resilience they possess. A qualitative approach of the descriptive phenomenological design was employed to address basic study objectives. The researcher purposely selected three blind graduate students from Sidist Kilo Campus and conducted a semi-structured interview to gather data. Data were analyzed by using thematic coding techniques. The present study found that personal characteristics such as commitment, living hope, motivation, positive self-esteem, self-confidence, and communication have shaped resiliency for successful university students with visual disabilities. The finding showed that the school environment is the place in which blind students had developed/experienced social, psychological, and economical competency and hope for their academic and entire life success. Furthermore, the finding showed that blind students had experienced individual, family, school, and community-related risks in the success track. Therefore, governmental and non-governmental organizations should provide training for students with visual impairments that focus on the individual traits that shape resilience for academic success, such as commitment, living hope, motivation, positive self-esteem, self-confidence, and communication and also community-oriented training should be to break the social stigma and discriminations for the individuals with the visual impairment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blind%20students" title="blind students">blind students</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20and%20protective%20factors" title=" risk and protective factors"> risk and protective factors</a>, <a href="https://publications.waset.org/abstracts/search?q=lived%20experience" title=" lived experience"> lived experience</a>, <a href="https://publications.waset.org/abstracts/search?q=success" title=" success"> success</a> </p> <a href="https://publications.waset.org/abstracts/168295/the-lived-experience-of-risk-and-protective-contexts-of-blind-successful-university-students-in-sidist-kilo-campus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168295.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> LiTa2PO8-based Composite Solid Polymer Electrolytes for High-Voltage Cathodes in Lithium-Metal Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kumlachew%20Zelalem%20Walle">Kumlachew Zelalem Walle</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Chen%20Yang"> Chun-Chen Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid-state Lithium metal batteries (SSLMBs) that contain polymer and ceramic solid electrolytes have received considerable attention as an alternative to substitute liquid electrolytes in lithium metal batteries (LMBs) for highly safe, excellent energy storage performance and stability under elevated temperature situations. Here, a novel fast Li-ion conducting material, LiTa₂PO₈ (LTPO), was synthesized and electrochemical performance of as-prepared powder and LTPO-incorporated composite solid polymer electrolyte (LTPO-CPE) membrane were investigated. The as-prepared LTPO powder was homogeneously dispersed in polymer matrices, and a hybrid solid electrolyte membrane was synthesized via a simple solution-casting method. The room temperature total ionic conductivity (σt) of the LTPO pellet and LTPO-CPE membrane were 0.14 and 0.57 mS cm-1, respectively. A coin battery with NCM811 cathode is cycled under 1C between 2.8 to 4.5 V at room temperature, achieving a Coulombic efficiency of 99.3% with capacity retention of 74.1% after 300 cycles. Similarly, the LFP cathode also delivered an excellent performance at 0.5C with an average Coulombic efficiency of 100% without virtually capacity loss (the maximum specific capacity is at 27th: 138 mAh g−1 and 500th: 131.3 mAh g−1). These results demonstrates the feasibility of a high Li-ion conductor LTPO as a filler, and the developed polymer/ceramic hybrid electrolyte has potential to be a high-performance electrolyte for high-voltage cathodes, which may provide a fresh platform for developing more advanced solid-state electrolytes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=li-ion%20conductor" title="li-ion conductor">li-ion conductor</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-metal%20batteries" title=" lithium-metal batteries"> lithium-metal batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20solid%20electrolytes" title=" composite solid electrolytes"> composite solid electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=liTa2PO8" title=" liTa2PO8"> liTa2PO8</a>, <a href="https://publications.waset.org/abstracts/search?q=high-voltage%20cathode" title=" high-voltage cathode"> high-voltage cathode</a> </p> <a href="https://publications.waset.org/abstracts/175159/lita2po8-based-composite-solid-polymer-electrolytes-for-high-voltage-cathodes-in-lithium-metal-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175159.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">66</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Assessment of Work-Related Stress and Its Predictors in Ethiopian Federal Bureau of Investigation in Addis Ababa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Markos%20Borko">Zelalem Markos Borko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Work-related stress is a reaction that occurs when the work weight progress toward becoming excessive. Therefore, unless properly managed, stress leads to high employee turnover, decreased performance, illness and absenteeism. Yet, little has been addressed regarding work-related stress and its predictors in the study area. Therefore, the objective of this study was to assess stress prevalence and its predictors in the study area. To that effect, a cross-sectional study design was conducted on 281 employees from the Ethiopian Federal Bureau of Investigation by using stratified random sampling techniques. Survey questionnaire scales were employed to collect data. Data were analyzed by percentage, Pearson correlation coefficients, simple linear regression, multiple linear regressions, independent t-test and one-way ANOVA statistical techniques. In the present study13.9% of participants faced high stress, whereas 13.5% of participants faced low stress and the rest 72.6% of officers experienced moderate stress. There is no significant group difference among workers due to age, gender, marital status, educational level, years of service and police rank. This study concludes that factors such as role conflict, performance over-utilization, role ambiguity, and qualitative and quantitative role overload together predict 39.6% of work-related stress. This indicates that 60.4% of the variation in stress is explained by other factors, so other additional research should be done to identify additional factors predicting stress. To prevent occupational stress among police, the Ethiopian Federal Bureau of Investigation should develop strategies based on factors that will help to develop stress reduction management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=work-related%20stress" title="work-related stress">work-related stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopian%20federal%20bureau%20of%20investigation" title=" Ethiopian federal bureau of investigation"> Ethiopian federal bureau of investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=predictors" title=" predictors"> predictors</a>, <a href="https://publications.waset.org/abstracts/search?q=Addis%20Ababa" title=" Addis Ababa"> Addis Ababa</a> </p> <a href="https://publications.waset.org/abstracts/168292/assessment-of-work-related-stress-and-its-predictors-in-ethiopian-federal-bureau-of-investigation-in-addis-ababa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168292.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Unsupervised Part-of-Speech Tagging for Amharic Using K-Means Clustering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Fantahun">Zelalem Fantahun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Part-of-speech tagging is the process of assigning a part-of-speech or other lexical class marker to each word into naturally occurring text. Part-of-speech tagging is the most fundamental and basic task almost in all natural language processing. In natural language processing, the problem of providing large amount of manually annotated data is a knowledge acquisition bottleneck. Since, Amharic is one of under-resourced language, the availability of tagged corpus is the bottleneck problem for natural language processing especially for POS tagging. A promising direction to tackle this problem is to provide a system that does not require manually tagged data. In unsupervised learning, the learner is not provided with classifications. Unsupervised algorithms seek out similarity between pieces of data in order to determine whether they can be characterized as forming a group. This paper explicates the development of unsupervised part-of-speech tagger using K-Means clustering for Amharic language since large amount of data is produced in day-to-day activities. In the development of the tagger, the following procedures are followed. First, the unlabeled data (raw text) is divided into 10 folds and tokenization phase takes place; at this level, the raw text is chunked at sentence level and then into words. The second phase is feature extraction which includes word frequency, syntactic and morphological features of a word. The third phase is clustering. Among different clustering algorithms, K-means is selected and implemented in this study that brings group of similar words together. The fourth phase is mapping, which deals with looking at each cluster carefully and the most common tag is assigned to a group. This study finds out two features that are capable of distinguishing one part-of-speech from others these are morphological feature and positional information and show that it is possible to use unsupervised learning for Amharic POS tagging. In order to increase performance of the unsupervised part-of-speech tagger, there is a need to incorporate other features that are not included in this study, such as semantic related information. Finally, based on experimental result, the performance of the system achieves a maximum of 81% accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=POS%20tagging" title="POS tagging">POS tagging</a>, <a href="https://publications.waset.org/abstracts/search?q=Amharic" title=" Amharic"> Amharic</a>, <a href="https://publications.waset.org/abstracts/search?q=unsupervised%20learning" title=" unsupervised learning"> unsupervised learning</a>, <a href="https://publications.waset.org/abstracts/search?q=k-means" title=" k-means"> k-means</a> </p> <a href="https://publications.waset.org/abstracts/84660/unsupervised-part-of-speech-tagging-for-amharic-using-k-means-clustering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84660.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Antecedents and Impacts of Human Capital Flight in the Sub-Saharan Africa with Specific Reference to the Higher Education Sector: Conceptual Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20B.%20Gurmessa">Zelalem B.

Africa in general and Sub-Saharan African (SSA) countries, in particular, are experiencing an exodus of highly trained, qualified and competent human resources to other developing and developed countries thereby threatening the overall development of the relevant regions and impeding both public and private service delivery systems in the nation states. The region is currently in a dire situation in terms of health care services, education, science, and technology. The contribution of SSA countries to Science, Technology and Innovation is relatively minimal owing to the migration of skilled professionals due to both push and pull factors. The phenomenon calls for both international and trans-boundary, regional, national and institutional interventions to curb the exodus. Based on secondary data and the review of the literature, the article conceptualizes the antecedents and impacts of human capital flight or brain drain in the SSA countries from a higher education perspective. To this end, the article explores the magnitude, causes, and impacts of brain drain in the region. Despite the lack of consistent data on the magnitude of academic brain drain in the region, a critical analysis of the existing sources shows that pay disparity between developing and developed countries, the lack of enabling working conditions at source countries, fear of security due to political turmoil or unrest, the availability of green pastures and opportunity for development in the receiving countries were identified as major factors contributing to academic brain drain in the region. This hampers the socio-economic, technological and political development of the region. The paper also recommends that further research can be undertaken on the magnitude, causes, characteristics and impact of brain drain on the sustainability and competitiveness of SSA higher education institutions in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20drain" title="brain drain">brain drain</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-Saharan%20Africa" title=" sub-Saharan Africa"> sub-Saharan Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/71715/antecedents-and-impacts-of-human-capital-flight-in-the-sub-saharan-africa-with-specific-reference-to-the-higher-education-sector-conceptual-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71715.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">258</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Community Perception towards the Major Drivers for Deforestation and Land Degradation of Choke Afro-alpine and Sub-afro alpine Ecosystem, Northwest Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Teshager">Zelalem Teshager</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Choke Mountains have several endangered and endemic wildlife species and provide important ecosystem services. Despite their environmental importance, the Choke Mountains are found in dangerous conditions. This raised the need for an evaluation of the community's perception of deforestation and its major drivers and suggested possible solutions in the Choke Mountains of northwestern Ethiopia. For this purpose, household surveys, key informant interviews, and focus group discussions were used. A total sample of 102 informants was used for this survey. A purposive sampling technique was applied to select the participants for in-depth interviews and focus group discussions. Both qualitative and quantitative data analyses were used. Computation of descriptive statistics such as mean, percentages, frequency, tables, figures, and graphs was applied to organize, analyze, and interpret the study. This study assessed smallholder agricultural land expansion, Fuel wood collection, population growth; encroachment, free grazing, high demand of construction wood, unplanned resettlement, unemployment, border conflict, lack of a strong forest protecting system, and drought were the serious causes of forest depletion reported by local communities. Loss of land productivity, Soil erosion, soil fertility decline, increasing wind velocity, rising temperature, and frequency of drought were the most perceived impacts of deforestation. Most of the farmers have a holistic understanding of forest cover change. Strengthening forest protection, improving soil and water conservation, enrichment planting, awareness creation, payment for ecosystem services, and zero grazing campaigns were mentioned as possible solutions to the current state of deforestation. Applications of Intervention measures, such as animal fattening, beekeeping, and fruit production can contribute to decreasing the deforestation causes and improve communities’ livelihood. In addition, concerted efforts of conservation will ensure that the forests’ ecosystems contribute to increased ecosystem services. The major drivers of deforestation should be addressed with government intervention to change dependency on forest resources, income sources of the people, and institutional set-up of the forestry sector. Overall, further reduction in anthropogenic pressure is urgent and crucial for the recovery of the afro-alpine vegetation and the interrelated endangered wildlife in the Choke Mountains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=choke%20afro-alpine" title="choke afro-alpine">choke afro-alpine</a>, <a href="https://publications.waset.org/abstracts/search?q=deforestation" title=" deforestation"> deforestation</a>, <a href="https://publications.waset.org/abstracts/search?q=drivers" title=" drivers"> drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention%20measures" title=" intervention measures"> intervention measures</a>, <a href="https://publications.waset.org/abstracts/search?q=perceptions" title=" perceptions"> perceptions</a> </p> <a href="https://publications.waset.org/abstracts/178816/community-perception-towards-the-major-drivers-for-deforestation-and-land-degradation-of-choke-afro-alpine-and-sub-afro-alpine-ecosystem-northwest-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178816.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">54</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Underage Internal Migration from Rural to Urban Areas of Ethiopia: The Perspective of Social Marketing in Controlling Child Labor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Belaynesh%20Tefera">Belaynesh Tefera</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mohammed"> Ahmed Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Bayisa"> Zelalem Bayisa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on the issue of underage internal migration from rural to urban areas in Ethiopia, specifically in the context of child labor. It addresses the significant disparities in living standards between rural and urban areas, which motivate individuals from rural areas to migrate to urban areas in search of better economic opportunities. The study was conducted in Addis Ababa, where there is a high prevalence of underage internal migrants engaged in child labor due to extreme poverty in rural parts of the country. The aim of this study is to explore the life experiences of shoe-makers who have migrated from rural areas of Ethiopia to Addis Ababa. The focus is on understanding the factors that push these underage individuals to migrate, the challenges they face, and the implications for child labor. This study adopts a qualitative approach, using semistructured face-to-face interviews with underage migrants. A total of 27 interviews were conducted in Addis Ababa, Ethiopia, until the point of data saturation. The criteria for selecting interviewees include working as shoemakers and migrating to Addis Ababa underage, below 16 years old. The interviews were audio-taped, transcribed into Amharic, and then translated into English for analysis. The study reveals that the major push factors for underage internal migration are socioeconomic and environmental factors. Despite improvements in living standards for underage migrants and their families, there is a high prevalence of child labor and lack of access to education among them. Most interviewees migrated without the accompaniment of their family members and faced various challenges, including sleeping on the streets. This study highlights the role of social marketing in addressing the issues of underage internal migration and child labor. It suggests that social marketing can be an effective strategy to protect children from abuse, loneliness, and harassment during their migration process. The data collection involved conducting in-depth interviews with the underage migrants. The interviews were transcribed and translated for analysis. The analysis focused on identifying common themes and patterns within the interview data. The study addresses the factors contributing to underage internal migration, the challenges faced by underage migrants, the prevalence of child labor, and the potential role of social marketing in addressing these issues. The study concludes that although Ethiopia has policies against child internal migration, it is difficult to protect underage laborers who migrate from rural to urban areas due to the voluntary nature of their migration. The study suggests that social marketing can serve as a solution to protect children from abuse and other challenges faced during migration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=underage" title="underage">underage</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20migration" title=" internal migration"> internal migration</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20marketing" title=" social marketing"> social marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20labor" title=" child labor"> child labor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/178579/underage-internal-migration-from-rural-to-urban-areas-of-ethiopia-the-perspective-of-social-marketing-in-controlling-child-labor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178579.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Garnet-based Bilayer Hybrid Solid Electrolyte for High-Voltage Cathode Material Modified with Composite Interface Enabler on Lithium-Metal Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kumlachew%20Zelalem%20Walle">Kumlachew Zelalem Walle</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Chen%20Yang"> Chun-Chen Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid-state lithium metal batteries (SSLMBs) are considered promising candidates for next-generation energy storage devices due to their superior energy density and excellent safety. However, recent findings have shown that the formation of lithium (Li) dendrites in SSLMBs still exhibits a terrible growth ability, which makes the development of SSLMBs have to face the challenges posed by the Li dendrite problem. In this work, an inorganic/organic mixture coating material (g-C3N4/ZIF-8/PVDF) was used to modify the surface of lithium metal anode (LMA). Then the modified LMA (denoted as g-C₃N₄@Li) was assembled with lithium nafion (LiNf) coated commercial NCM811 (LiNf@NCM811) using a bilayer hybrid solid electrolyte (Bi-HSE) that incorporated 20 wt.% (vs. polymer) LiNf coated Li6.05Ga0.25La3Zr2O11.8F0.2 (<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="337f5a7d55737f74031d01067f697c75">[email protected]</a>) filler faced to the positive electrode and the other layer with 80 wt.% (vs. polymer) filler content faced to the g-C₃N₄@Li. The garnet-type Li6.05Ga0.25La3Zr2O11.8F0.2 (LG0.25LZOF) solid electrolyte was prepared via co-precipitation reaction process from Taylor flow reactor and modified using lithium nafion (LiNf), a Li-ion conducting polymer. The Bi-HSE exhibited high ionic conductivity of 6.8  10–4 S cm–1 at room temperature, and a wide electrochemical window (0–5.0 V vs. Li/Li+). The coin cell was charged between 2.8 to 4.5 V at 0.2C and delivered an initial specific discharge capacity of 194.3 mAh g–1 and after 100 cycles it maintained 81.8% of its initial capacity at room temperature. The presence of a nano-sheet g-C3N4/ZIF-8/PVDF as a composite coating material on the LMA surface suppress the dendrite growth and enhance the compatibility as well as the interfacial contact between anode/electrolyte membrane. The g-C3N4@Li symmetrical cells incorporating this hybrid electrolyte possessed excellent interfacial stability over 1000 h at 0.1 mA cm–2 and a high critical current density (1 mA cm–2). Moreover, the in-situ formation of Li3N on the solid electrolyte interface (SEI) layer as depicted from the XPS result also improves the ionic conductivity and interface contact during the charge/discharge process. Therefore, these novel multi-layered fabrication strategies of hybrid/composite solid electrolyte membranes and modification of the LMA surface using mixed coating materials have potential applications in the preparation of highly safe high-voltage cathodes for SSLMBs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-voltage%20cathodes" title="high-voltage cathodes">high-voltage cathodes</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20solid%20electrolytes" title=" hybrid solid electrolytes"> hybrid solid electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=garnet" title=" garnet"> garnet</a>, <a href="https://publications.waset.org/abstracts/search?q=graphitic-carbon%20nitride%20%28g-C3N4%29" title=" graphitic-carbon nitride (g-C3N4)"> graphitic-carbon nitride (g-C3N4)</a>, <a href="https://publications.waset.org/abstracts/search?q=ZIF-8%20MOF" title=" ZIF-8 MOF"> ZIF-8 MOF</a> </p> <a href="https://publications.waset.org/abstracts/175160/garnet-based-bilayer-hybrid-solid-electrolyte-for-high-voltage-cathode-material-modified-with-composite-interface-enabler-on-lithium-metal-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175160.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Reducing Road Traffic Accident: Rapid Evidence Synthesis for Low and Middle Income Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Dagne">Tesfaye Dagne</a>, <a href="https://publications.waset.org/abstracts/search?q=Dagmawit%20Solomon"> Dagmawit Solomon</a>, <a href="https://publications.waset.org/abstracts/search?q=Firmaye%20Bogale"> Firmaye Bogale</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosef%20Gebreyohannes"> Yosef Gebreyohannes</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Mideksa"> Samson Mideksa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamuye%20Hadis"> Mamuye Hadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Desalegn%20Ararso"> Desalegn Ararso</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermias%20Woldie"> Ermias Woldie</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegaye%20Getachew"> Tsegaye Getachew</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabit%20Ababor"> Sabit Ababor</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Kebede"> Zelalem Kebede</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Globally, road traffic accident (RTA) is causing millions of deaths and injuries every year. It is one of the leading causes of death among people of all age groups and the problem is worse among young reproductive age group. Moreover the problem is increasing with an increasing number of vehicles. The majority of the problem happen in low and middle income countries (LMIC), even if the number of vehicles in these countries is low compared to their population. So, the objective of this paper is to summarize the best available evidence on interventions that can reduce road traffic accidents in low and middle income countries (LMIC). Method: A rapid evidence synthesis approach adapted from the SURE Rapid Response Service was applied to search, appraise and summarize the best available evidence on effective intervention in reducing road traffic injury. To answer the question under review, we searched for relevant studies from databases including PubMed, the Cochrane Library, TRANSPORT, Health system evidence, Epistemonikos, and SUPPORT summary. The following key terms were used for searching: Road traffic accident, RTA, Injury, Reduc*, Prevent*, Minimiz*, “Low and middle-income country”, LMIC. We found 18 articles through a search of different databases mentioned above. After screening for the titles and abstracts of the articles, four of them which satisfy the inclusion criteria were included in the final review. Then we appraised and graded the methodological quality of systematic reviews that are deemed to be highly relevant using AMSTAR. Finding: The identified interventions to reduce road traffic accidents were legislation and enforcement, public awareness/education, speed control/ rumble strips, road improvement, mandatory motorcycle helmet, graduated driver license, street lighting. Legislation and Enforcement: Legislation focusing on mandatory motorcycle helmet usage, banning cellular phone usage when driving, seat belt laws, decreasing the legal blood alcohol content (BAC) level from 0.06 g/L to 0.02 g/L bring the best result where enforcement is there. Public Awareness/Education: focusing on seat belt use, child restraint use, educational training in health centers and schools/universities, and public awareness with media through the distribution of videos, posters/souvenirs, and pamphlets are effective in the short run. Speed Control: through traffic calming bumps, or speed bumps, rumbled strips are effective in reducing accidents and fatality. Mandatory Motorcycle Helmet: is associated with reduction in mortality. Graduated driver’s license (GDL): reduce road traffic injury by 19%. Street lighting: is a low-cost intervention which may reduce road traffic accidents. <p class="card-text"><strong>Keywords:</strong> <a
