They were obtained in a good yield (59.5-85%) by applying different chemical reactions like cyclization and condensation reactions. The chemical structure of the final compounds was also verified by spectroscopic methods (IR, ¹HNMR) and elemental microanalysis. The in vivo antimalarial activity of these compounds on P. berghei infected mice was found to be moderate to high at an oral dose of 0.04846 mmol/kg /day. This is equal to 25 mg/kg of chloroquine phosphate, which causes 100% inhibition of the parasite. It is worth mentioning that most active compounds (E) -3 Phenyl -2- [2- (pyridine -4- yl) vinyl] -4 (3H) -quinazolinone IVa (64.02%, (E)-2-[2-(4 - Hydroxy-3 - methoxystyryl) - vinyl) -3 - phenyl -4 (3H ) - quinazolinone IVc (77.25%) and (E)-2 –[2 –(Pyridin -4-yl) –vinyl] -3 phenenylamine -4(3H) quinazolinone IVe (73.54%) showed a dose-dependent increase in present suppression in antimalarial activities. Furthermore, the synthesized compounds were screened for their in vitro antileishmanial activity against L. aethiopica isolate (CL/039/09). All tested compounds (IVa (0.03766 ug/ml), IVb (0.00538 ug/ml, IVc (0.00412 ug/ml, IVd (0.00110 ug/ml), IVe (0.03017 ug/ml) and IVf (0.03894 ug/ml)) showed excellent potency that is much better than amphotericin B (IC50 = 0,04359 ug/ml). The results of acute toxicity indicated that all test compounds (IVa –IVf) proved to be nontoxic and well tolerated by the experimental animals up to 300 mg/kg in oral and 140 mg/kg in parental studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=4%283H%29-quinazolinone" title="4(3H)-quinazolinone">4(3H)-quinazolinone</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vivo%20antimalarial%20activity" title=" in vivo antimalarial activity"> in vivo antimalarial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro%20antileishmanial%20activity" title=" in vitro antileishmanial activity"> in vitro antileishmanial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20toxicity" title=" acute toxicity"> acute toxicity</a> </p> <a href="https://publications.waset.org/abstracts/153719/43h-quinazolinone-derivatives-synthesis-and-evaluation-as-antimalarial-and-anti-leishmanial-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153719.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">100</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">75</span> Solving the Overheating on the Top Floor of Energy Efficient Houses: The Envelope Improvement </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sormeh%20Sharifi">Sormeh Sharifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wasim%20Saman"> Wasim Saman</a>, <a href="https://publications.waset.org/abstracts/search?q=Alemu%20Alemu"> Alemu Alemu</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Whaley"> David Whaley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although various energy rating schemes and compulsory building codes are using around the world, there are increasing reports on overheating in energy efficient dwellings. Given that the cooling demand of buildings is rising globally because of the climate change, it is more likely that the overheating issue will be observed more. This paper studied the summer indoor temperature in eight air-conditioned multi-level houses in Adelaide which have complied with the Australian Nationwide Houses Energy Rating Scheme (NatHERS) minimum energy performance of 7.5 stars. Through monitored temperature, this study explores that overheating is experienced on 75.5% of top floors during cooling periods while the air-conditioners were running. This paper found that the energy efficiency regulations have significantly improved thermal comfort in low floors, but not on top floors, and the energy-efficient house is not necessarily adapted with the air temperature fluctuations particularly on top floors. Based on the results, this study suggests that the envelope of top floors for multi-level houses in South Australian context need new criteria to make the top floor more heat resistance in order to: preventing the overheating, reducing the summer pick electricity demand and providing thermal comfort. Some methods are used to improve the envelope of the eight case studies. The results demonstrate that improving roofs was the most effective part of the top floors envelope in terms of reducing the overheating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20code" title="building code">building code</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-efficient%20building" title=" energy-efficient building"> energy-efficient building</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20rating" title=" energy rating"> energy rating</a>, <a href="https://publications.waset.org/abstracts/search?q=overheating" title=" overheating"> overheating</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a> </p> <a href="https://publications.waset.org/abstracts/88843/solving-the-overheating-on-the-top-floor-of-energy-efficient-houses-the-envelope-improvement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88843.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">220</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">74</span> Understand and Redefine Lean Product Development </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alemu%20Moges%20Belay">Alemu Moges Belay</a>, <a href="https://publications.waset.org/abstracts/search?q=Torgeir%20Welo"> Torgeir Welo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Ola%20Strandhagen"> Jan Ola Strandhagen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lean has long been linked with manufacturing, but its application claimed also by other functions such as product development and services.

The data was collected from secondary and primary. Ethiopia has been operating in the floriculture industry for over 20 years. As is the case in many developing countries, the major export items of Ethiopia are dominated by few agricultural products that earn very small amounts in the international market. Moreover, most of the exports are destined to only few countries. Given the highly capital intensive nature of production and processing, rose farming is not a smallholder activity. It is also important to note the extremely tightly controlled time dimension of the logistics process, given the product attributes desired and the fragility and perishability of the roses. Another characteristic of the Ethiopian floriculture sector is the lack of domestically produced inputs that flower producers can access. The export volume and value of cut-flowers accounts for a small proportion of the total exports of Ethiopia. In recent years the sector is showing improvements in terms of the quality and quantity of exports to the international market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roses" title="roses">roses</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20chain" title=" value chain"> value chain</a>, <a href="https://publications.waset.org/abstracts/search?q=floriculture" title=" floriculture"> floriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=supply" title=" supply"> supply</a> </p> <a href="https://publications.waset.org/abstracts/23293/supply-and-marketing-of-floriculture-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23293.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">380</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">71</span> The Role of Indigenous Informal Local Institutions and Social Capital for Adoption of Agricultural Innovation: A Special Emphasis in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Molla%20Tadesse%20Lakew">Molla Tadesse Lakew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Researchers tried to find out the socio-economic and supply-side constraint factors to adoption.

Based on its contents, relevancy, and time duration, only 121 (journals, books, and paper reports) were selected. It concludes that social capital has an indispensable role in facilitating cooperation and connection between members of the farmers' community, informal and experiential knowledge sharing, and access to research-based knowledge and contributes to reducing the transaction cost of adoption. On the contrary, inside the black box of social capital, the negative effects include the exclusion of outsider’s knowledge and experiences, excessive claims on group members, and restrictions on individual freedom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20capital" title="social capital">social capital</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20institutions" title=" local institutions"> local institutions</a>, <a href="https://publications.waset.org/abstracts/search?q=adoption" title=" adoption"> adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/177243/the-role-of-indigenous-informal-local-institutions-and-social-capital-for-adoption-of-agricultural-innovation-a-special-emphasis-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177243.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">96</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">70</span> Experts' Perception of Secondary Education Quality Management Challenges in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aklilu%20Alemu">Aklilu Alemu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tak%20Cheung%20Chan"> Tak Cheung Chan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following the intensification of secondary education in the developing world, the attention of Ethiopia has currently shifted to its quality education and its management. This study is aimed to explore experts’ perceptions of quality management challenges in secondary education in Ethiopia. The researchers employed a case study design recruiting participating supervisors from the Ministry of Education, region, zone, wereda, and cluster by using a purposeful sampling technique. Twenty-six interviewees took part in this study. The researchers employed NVivo 8 versions together with a thematic analysis process to analyze the data. This study revealed that major problems that affected quality management practices in Ethiopia were: lack of qualified experts at all levels; lack of accountability in every echelon; the changing nature of teacher education; the ineffectiveness of teacher-licensing programs; and lack of educational budget and the problem of utilizing this limited budget. The study concluded that the experts at different levels were not genuinely fulfilling their roles and responsibilities. Therefore, the Ministry of Finance and Economic Development, together with the concerned parties, needs to reconsider budget allocation for secondary education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education%20quality" title="education quality">education quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20challenge" title=" quality challenge"> quality challenge</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20management" title=" quality management"> quality management</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20education" title=" secondary education"> secondary education</a> </p> <a href="https://publications.waset.org/abstracts/144531/experts-perception-of-secondary-education-quality-management-challenges-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144531.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">216</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">69</span> Climate Change and Variability-Induced Resource Based Conflicts: The Case of the Issa, Ittu and Afar (Agro) Pastoralists of Eastern Ethiopia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bamlaku%20Tadesse%20Mengistu">Bamlaku Tadesse Mengistu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article explores the link between climate change/variability and its adaptation/coping strategies with resource-based ethnic conflicts among the Afar, Issa-Somali, and Ittu-Oromo ethnic groups. The qualitative data were collected from community leaders, ordinary members of the communities, and administrative and political bodies at various levels through one-on-one interviews, focus group discussions and field observations. The quantitative data were also collected through a household survey from the randomly selected 128 households drawn from the three districts of Mieso-Mullu, Mieso, and Amibara districts. The study shows that there is a causal relationship between resource scarcity impacted by climate change/variability and ethnic conflicts. The study reveals that the increasing nature of resource scarcity and environmental problems, and also the changing nature of ethnic diversity will aggravate the resource-based inter-ethnic conflicts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eastern%20Ethiopia" title="Eastern Ethiopia">Eastern Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnic%20conflict" title=" ethnic conflict"> ethnic conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=Afar" title=" Afar"> Afar</a>, <a href="https://publications.waset.org/abstracts/search?q=Issa" title=" Issa"> Issa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ittu" title=" Ittu"> Ittu</a> </p> <a href="https://publications.waset.org/abstracts/109664/climate-change-and-variability-induced-resource-based-conflicts-the-case-of-the-issa-ittu-and-afar-agro-pastoralists-of-eastern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109664.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">195</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">68</span> Coexistence of Superconductivity and Spin Density Wave in Ferropnictide Ba₁₋ₓKₓFe₂As₂</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadesse%20Desta%20Gidey">Tadesse Desta Gidey</a>, <a href="https://publications.waset.org/abstracts/search?q=Gebregziabher%20Kahsay"> Gebregziabher Kahsay</a>, <a href="https://publications.waset.org/abstracts/search?q=Pooran%20Singh"> Pooran Singh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on the theoretical investigation of the coexistence of superconductivity and Spin Density Wave (SDW)in Ferropnictide Ba₁₋ₓKₓFe₂As₂.

By employing the experimental and theoretical values of the parameters in the obtained expressions, phase diagrams of superconducting transition temperature (TC) versus superconducting order parameter (Sc) and spin density wave transition temperature (Tsdw), versus spin density wave order parameter (sdw) have been plotted. By combining the two phase diagrams, we have demonstrated the possible coexistence of superconductivity and spin density wave (SDW) in ferropnictide Ba1−xKxFe2As2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Superconductivity" title="Superconductivity">Superconductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Spin%20density%20wave" title=" Spin density wave"> Spin density wave</a>, <a href="https://publications.waset.org/abstracts/search?q=Coexistence" title=" Coexistence"> Coexistence</a>, <a href="https://publications.waset.org/abstracts/search?q=Green%20function" title=" Green function"> Green function</a>, <a href="https://publications.waset.org/abstracts/search?q=Pnictides" title=" Pnictides"> Pnictides</a>, <a href="https://publications.waset.org/abstracts/search?q=Ba%E2%82%81%E2%82%8B%E2%82%93K%E2%82%93Fe%E2%82%82As%E2%82%82" title=" Ba₁₋ₓKₓFe₂As₂"> Ba₁₋ₓKₓFe₂As₂</a> </p> <a href="https://publications.waset.org/abstracts/119138/coexistence-of-superconductivity-and-spin-density-wave-in-ferropnictide-ba1kfe2as2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119138.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">173</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">67</span> The Effect of Customs Commission Customer Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Menelik%20Tilahun%20Alemu">Menelik Tilahun Alemu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Customs administrations are now increasingly regarded as the key border agencies responsible for all transactions related to issues arising from the border crossings of goods and people. Raising revenue has traditionally been high on the agenda of governments, represented by the Ministry of Finance (MOF), because of the critical importance of import duties as a source of budget revenue for many developing countries. Most of these functions are undertaken in close cooperation with other national agencies. Due to the need to make structural reforms that consider the nature of business activities in the world and the needs of consumers, the institution was previously divided into the Ministry of Revenue and the Customs Commission. Accordingly, the Ministry of Revenue is primarily responsible for administering and collecting local taxes, while the Customs Commission is responsible for administering customs matters; It supports exports and collects revenue from it. The National Import and Export Trade Service System is working to make the world more transparent and standardized and adapt to the current situation by formulating various guidelines, rules and procedures to provide a clear, simple, predictable and accessible service to customers. As a result, the commission will be able to streamline the business process by enabling Paperless customer service to support the service delivery technology and eliminate the customer iteration without having to incur unnecessary costs and inconveniences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business" title="business">business</a>, <a href="https://publications.waset.org/abstracts/search?q=consumers" title=" consumers"> consumers</a>, <a href="https://publications.waset.org/abstracts/search?q=adapt" title=" adapt"> adapt</a>, <a href="https://publications.waset.org/abstracts/search?q=transparent" title=" transparent"> transparent</a> </p> <a href="https://publications.waset.org/abstracts/183711/the-effect-of-customs-commission-customer-satisfaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183711.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">50</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">66</span> Analysis of Drought Flood Abrupt Alternation Events and there Impacts in Kenya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Betty%20Makena">Betty Makena</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegaye%20Tadesse"> Tsegaye Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Svoboda"> Mark Svoboda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global warming has intensified the frequency and intensity of extreme climate disasters and led to unpredictable weather conditions. Consequently, rapid shifts between drought and floods, known as Drought-Flood Abrupt Alteration (DFAA), have become increasingly common. DFAA results in superimposed impacts of drought and floods within a short period, exacerbating the effects of the floods or drought event. Current disaster management plans often overlook DFAA events, as they primarily focus on either floods or drought. Therefore, effectively identifying DFAA events is crucial for developing effective mitigation strategies. This study aims to identify historical DFAA events in Kenya using the Long Cycle Drought-Flood Abrupt Alteration Index (LDFAI). The research will analyze the spatial distribution, temporal variation, and intensity of DFAA events from 1990 to 2023, as well as their socio-economic impacts. Understanding these events is important to develop more effective strategies to address the impacts of DFAA events. Findings from this study will inform decision making to develop coping strategies to mitigate the adverse effects of DFAA in Kenya. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abrupt" title="abrupt">abrupt</a>, <a href="https://publications.waset.org/abstracts/search?q=alteration" title=" alteration"> alteration</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=floods" title=" floods"> floods</a> </p> <a href="https://publications.waset.org/abstracts/169721/analysis-of-drought-flood-abrupt-alternation-events-and-there-impacts-in-kenya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169721.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">69</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">65</span> Inclusion of Students with Disabilities (SWD) in Higher Education Institutions (HEIs): Self-Advocacy and Engagement as Central</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadesse%20Abera">Tadesse Abera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to investigate the contribution of self-advocacy and engagement in the inclusion of SWDs in HEIs. A convergent parallel mixed methods design was employed. This article reports the quantitative strand. A total of 246 SWDs were selected through stratified proportionate random sampling technique from five public HEIs in Ethiopia. Data were collected through Self-advocacy questionnaire, student engagement scale, and college student experience questionnaire and analyzed through frequency, percentage, mean, standard deviation, correlation, one sample t-test and multiple regression. Both self-advocacy and engagement were found to have a predictive power on inclusion of respondents in the HEIs, where engagement was found to be more predictor. From the components of self-advocacy, knowledge of self and leadership and from engagement dimensions sense of belonging, cognitive, and valuing in their respective orders were found to have a stronger predictive power on the inclusion of respondents in the institutions. Based on the findings it was concluded that, if students with disabilities work hard to be self-determined, strive for realizing social justice, exert quality effort and seek active involvement, their inclusion in the institutions would be ensured. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-advocacy" title="self-advocacy">self-advocacy</a>, <a href="https://publications.waset.org/abstracts/search?q=engagement" title=" engagement"> engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=students%20with%20disabilities" title=" students with disabilities"> students with disabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education%20institution" title=" higher education institution"> higher education institution</a> </p> <a href="https://publications.waset.org/abstracts/179656/inclusion-of-students-with-disabilities-swd-in-higher-education-institutions-heis-self-advocacy-and-engagement-as-central" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179656.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">75</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">64</span> Automatic Assignment of Geminate and Epenthetic Vowel for Amharic Text-to-Speech System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadesse%20Anberbir">Tadesse Anberbir</a>, <a href="https://publications.waset.org/abstracts/search?q=Felix%20Bankole"> Felix Bankole</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomio%20Takara"> Tomio Takara</a>, <a href="https://publications.waset.org/abstracts/search?q=Girma%20Mamo"> Girma Mamo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the development of a text-to-speech synthesizer, automatic derivation of correct pronunciation from the grapheme form of a text is a central problem. Particularly deriving phonological features which are not shown in orthography is challenging. In the Amharic language, geminates and epenthetic vowels are very crucial for proper pronunciation but neither is shown in orthography. In this paper, we proposed and integrated a morphological analyzer into an Amharic Text-to-Speech system, mainly to predict geminates and epenthetic vowel positions, and prepared a duration modeling method. Amharic Text-to-Speech system (AmhTTS) is a parametric and rule-based system that adopts a cepstral method and uses a source filter model for speech production and a Log Magnitude Approximation (LMA) filter as the vocal tract filter. The naturalness of the system after employing the duration modeling was evaluated by sentence listening test and we achieved an average Mean Opinion Score (MOS) 3.4 (68%) which is moderate. By modeling the duration of geminates and controlling the locations of epenthetic vowel, we are able to synthesize good quality speech. Our system is mainly suitable to be customized for other Ethiopian languages with limited resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amharic" title="Amharic">Amharic</a>, <a href="https://publications.waset.org/abstracts/search?q=gemination" title=" gemination"> gemination</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20synthesis" title=" speech synthesis"> speech synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=epenthesis" title=" epenthesis"> epenthesis</a> </p> <a href="https://publications.waset.org/abstracts/171525/automatic-assignment-of-geminate-and-epenthetic-vowel-for-amharic-text-to-speech-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171525.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">87</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">63</span> The Determinants of Trade Flow and Potential between Ethiopia and Group of Twenty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terefe%20Alemu">Terefe Alemu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is intended to examine Ethiopia’s trade flow determinants and trade potential with G20 countries whether it was overtraded or there is/are trade potential by using trade gravity model.

IRSs are electromagnetic (EM) surfaces that are fabricated and have integrated electronics, electronically controlled processes, and particularly wireless communication features. IRSs operate without the need for complex signal processing and the encoding and decoding steps that improve the signal quality at the receiver. Improving vital performance parameters such as energy efficiency (EE) and spectral efficiency (SE) have frequently been the primary goals of research in order to meet the increasing requirements for advanced services in the future 6G communications. In this research, we conduct a comparative analysis on single and multi-IRS wireless communication networks using energy and spectrum efficiency. The energy efficiency versus user distance, energy efficiency versus signal to noise ratio, and spectral efficiency versus user distance are the basis for our result with 1, 2, 4, and 6 IRSs. According to the results of our simulation, in terms of energy and spectral efficiency, six IRS perform better than four, two, and single IRS. Overall, our results suggest that multi-IRS-assisted wireless communication systems outperform single IRS systems in terms of communication performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sixth-generation%20%286G%29" title="sixth-generation (6G)">sixth-generation (6G)</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20networks" title=" wireless networks"> wireless networks</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20reflecting%20surfaces" title=" intelligent reflecting surfaces"> intelligent reflecting surfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20efficiency" title=" spectral efficiency"> spectral efficiency</a> </p> <a href="https://publications.waset.org/abstracts/191794/comparative-analysis-of-single-versus-multi-irs-assisted-multi-user-wireless-communication-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191794.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">25</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">61</span> Rainfall and Temperature Characteristics of the Middle and Lower Awash Areas of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melese%20Tadesse%20Morebo">Melese Tadesse Morebo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pastoral and agro-pastoral communities in East Africa, particularly in Ethiopia, are vulnerable to climate-related risks.

Emerging studies have indicated that involving men in ECE can yield positive outcomes for children's physical and psychological development. Challenging the prevailing misconception and stereotype that women dominate the ECE sector is crucial. In light of this, the present study undertakes a systematic review of nine studies on males working in ECE, revealing a dearth of male presence in the field in China as well. To address this issue, substantial structural changes must be implemented to enhance the inadequate pay and working conditions that dissuade both men and women from pursuing a sustainable career in ECE. It is recommended that school leadership raise awareness among female teachers and parents, encouraging them to support and uphold virtuous values for male teachers. Additionally, governing bodies should provide explicit guidelines during training programs to address concerns regarding potential abuse and gender biases. The findings of this review underscore the need for future studies to examine the self-identities of male teachers from various stakeholders' perspectives and explore the consequences of being in the profession through rigorous and robust methodologies that can inform policymakers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=male%20teachers" title="male teachers">male teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=Early%20Childhood%20Education%20%28ECE%29" title=" Early Childhood Education (ECE)"> Early Childhood Education (ECE)</a>, <a href="https://publications.waset.org/abstracts/search?q=self-identity" title=" self-identity"> self-identity</a>, <a href="https://publications.waset.org/abstracts/search?q=perception%20of%20stakeholders" title=" perception of stakeholders"> perception of stakeholders</a> </p> <a href="https://publications.waset.org/abstracts/186171/the-perception-of-stallholders-about-the-early-childhood-education-male-teachers-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186171.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">38</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">59</span> Effect of Chemical Concentration on the Rheology of Inks for Inkjet Printing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20G.%20Tadesse">M.

In this work, we optimized the viscosity and surface tension of inkjet inks by varying the concentration of glycerol with water, PEDOT:PSS with glycerol and water, finally by adding the surfactant. The surface resistance of the sample was characterized by four-probe measurement principle. The change in volume of PEDOT:PSS in water, as well as the change in weight of glycerol in water has got a great influence on the viscosity on both temperature dependence and shear dependence behavior of the ink solution. The surface tension of the solution changed from 37 to 28 mN/m due to the addition of Triton. Varying the volume of PEDOT:PSS and the volume of glycerol in water has a great influence on the viscosity of the ink solution for inkjet printing. Viscosity drops from 12.5 to 9.5 mPa s with the addition of Triton at 25 oC. The PEDOT:PSS solution was found to be temperature dependence but not shear dependence as it is a Newtonian fluid. The sample was used to connect the light emitting diode (LED), and hence the electrical conductivity, with a surface resistance of 0.158 KΩ/square, was sufficient enough to give transfer current for LED lamp. The rheology of the inkjet ink is very critical for the successful droplet formation of the inkjet printing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20rate" title="shear rate">shear rate</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20tension" title=" surface tension"> surface tension</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactant" title=" surfactant"> surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a> </p> <a href="https://publications.waset.org/abstracts/84426/effect-of-chemical-concentration-on-the-rheology-of-inks-for-inkjet-printing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84426.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">172</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">58</span> Servant Leadership and Organizational Citizenship Behavior: The Mediating Role of Perceived Organizational Politics and the Moderating Role of Political Skill in Public Service Organizations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debalkie%20Demissie%20Addisu">Debalkie Demissie Addisu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ejigu%20Alemu%20Abebe"> Ejigu Alemu Abebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegay%20Tensay%20Assefa"> Tsegay Tensay Assefa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the indirect effect of servant leadership on organizational citizenship behavior through perceptions of organizational politics moderated by political skill. This study reports the responses of 321 respondents from six federal public service organizations in Ethiopia. A multi-stage random sampling procedure was employed to select the sampled federal public service organizations. To test hypotheses, the study employed structural equation modeling using AMOS version-26 software. The result revealed that all direct effects have a significant effect. Specifically, servant leadership has a positive effect on organizational citizenship behavior. Likewise, servant leadership has a negative effect on perceptions of organizational politics. Also, a perception of organizational politics has a negative effect on organizational citizenship behavior. Moreover, perceptions of organizational politics competitively mediated the effect of servant leadership on organizational citizenship behavior. As well, political skill moderated the effect of perceptions of organizational politics on organizational citizenship behavior but not the indirect effect. To the best of our knowledge, no one else employs perceptions of organizational politics as a mediating effect between servant leadership and organizational citizenship behavior. Furthermore, we are not aware of anyone else employing political skill as a moderating role in the indirect effect of servant leadership on organizational citizenship behavior through perceptions of organizational politics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=servant%20leadership" title="servant leadership">servant leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20citizenship%20behavior" title=" organizational citizenship behavior"> organizational citizenship behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=perceptions%20of%20organizational%20politics" title=" perceptions of organizational politics"> perceptions of organizational politics</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20skill" title=" political skill"> political skill</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20service%20organization" title=" public service organization"> public service organization</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/184595/servant-leadership-and-organizational-citizenship-behavior-the-mediating-role-of-perceived-organizational-politics-and-the-moderating-role-of-political-skill-in-public-service-organizations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184595.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">68</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">57</span> A Milky-White Stream Water Suitability for Drinking Purpose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kassahun%20Tadesse">Kassahun Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Megersa%20O.%20Dinka"> Megersa O.

Water samples were taken from the water source and physicochemical properties were analyzed based on standard methods. The mean values of pH, total dissolved solids, sodium, magnesium, potassium, manganese, chloride, boron, and fluoride were within maximum permissible limits set for health. Whereas turbidity, calcium, irons, hardness, alkalinity, nitrate, and sulfate contents were above the limits. The water is very hard water due to high calcium content. High sulfate content can cause noticeable taste and a laxative (gastrointestinal) effect. The nitrate content was very high and can cause methemoglobinemia (blue baby syndrome) which is a temporary blood disorder in the bottle fed infants. Hence, parents should be advised not to give this water to infants. In conclusion, all physicochemical parameters except for nitrate are safe for health but may affect the appearance and taste, and wear water infrastructures. A high value of turbidity due to suspended minerals is the cause for milky-white colour. However, a mineralogical analysis of suspended sediments is required to identify the exact cause for white colour, and a study on sediment source was recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hard%20water" title="hard water">hard water</a>, <a href="https://publications.waset.org/abstracts/search?q=laxative%20effect" title=" laxative effect"> laxative effect</a>, <a href="https://publications.waset.org/abstracts/search?q=methemoglobinemia" title=" methemoglobinemia"> methemoglobinemia</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate" title=" nitrate"> nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical" title=" physicochemical"> physicochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality "> water quality </a> </p> <a href="https://publications.waset.org/abstracts/81840/a-milky-white-stream-water-suitability-for-drinking-purpose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81840.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">194</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">56</span> Survey and Identification of Coinfecting Botryosphaeriales Causing Stem Canker Diseases of Eucalyptus camaldulensis in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wendu%20Admasu">Wendu Admasu</a>, <a href="https://publications.waset.org/abstracts/search?q=Assefa%20Sintayehu"> Assefa Sintayehu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alemu%20Gezahgne"> Alemu Gezahgne</a>, <a href="https://publications.waset.org/abstracts/search?q=Zewdu%20Terefework"> Zewdu Terefework</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eucalyptus is the most widely planted forest tree species in the world. In Ethiopia, pathogenic fungi pose an increasing threat to Eucalyptus species. Due to limited research, there is insufficient information on the associated diseases and pathogens. This study investigated Eucalyptus diseases, the extent of their damage, and the causal fungal pathogens. A Eucalyptus disease survey was conducted in the Eucalyptus forestry areas of Ethiopia during the growth years 2019/20 and 2020/21. Disease assessment and sampling were carried out in eighteen plantations at nine locations. E. camaldulensis was the most dominant species planted in the surveyed areas. The field study shows a high incidence and severity of canker diseases. Diseased stem and branch samples were collected, cultured on malt extract agar media and studied. The results of morphological and ITS sequence analysis confirmed that the fungal species Neofusicoccum parvum, Lasiodiplodia theobromae, and Aplosporella hesperidica caused the observed canker symptoms. This is the first report of Lasiodiplodia theobromae and Aplosporella hesperidica causing diseases in Eucalyptus plants in Ethiopia. Changes in global climate and environmental factors, such as altitude, are believed to have a strong impact on the susceptibility of Eucalyptus plants to diseases. Strict quarantine practices and continuous monitoring of pathogenic and endophytic fungal species associated with Eucalyptus trees are issued to be prioritized to effectively control and manage the disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neofusicoccum" title="Neofusicoccum">Neofusicoccum</a>, <a href="https://publications.waset.org/abstracts/search?q=Lasiodiplodia" title=" Lasiodiplodia"> Lasiodiplodia</a>, <a href="https://publications.waset.org/abstracts/search?q=Aplosporella" title=" Aplosporella"> Aplosporella</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenicity" title=" pathogenicity"> pathogenicity</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogeny" title=" phylogeny"> phylogeny</a>, <a href="https://publications.waset.org/abstracts/search?q=severity" title=" severity"> severity</a> </p> <a href="https://publications.waset.org/abstracts/179366/survey-and-identification-of-coinfecting-botryosphaeriales-causing-stem-canker-diseases-of-eucalyptus-camaldulensis-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179366.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">69</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">55</span> Automatic Detection and Filtering of Negative Emotion-Bearing Contents from Social Media in Amharic Using Sentiment Analysis and Deep Learning Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Derejaw%20Lake%20Melie">Derejaw Lake Melie</a>, <a href="https://publications.waset.org/abstracts/search?q=Alemu%20Kumlachew%20Tegegne"> Alemu Kumlachew Tegegne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing prevalence of social media in Ethiopia has exacerbated societal challenges by fostering the proliferation of negative emotional posts and comments. Illicit use of social media has further exacerbated divisions among the population. Addressing these issues through manual identification and aggregation of emotions from millions of users for swift decision-making poses significant challenges, particularly given the rapid growth of Amharic language usage on social platforms. Consequently, there is a critical need to develop an intelligent system capable of automatically detecting and categorizing negative emotional content into social, religious, and political categories while also filtering out toxic online content. This paper aims to leverage sentiment analysis techniques to achieve automatic detection and filtering of negative emotional content from Amharic social media texts, employing a comparative study of deep learning algorithms. The study utilized a dataset comprising 29,962 comments collected from social media platforms using comment exporter software. Data pre-processing techniques were applied to enhance data quality, followed by the implementation of deep learning methods for training, testing, and evaluation. The results showed that CNN, GRU, LSTM, and Bi-LSTM classification models achieved accuracies of 83%, 50%, 84%, and 86%, respectively. Among these models, Bi-LSTM demonstrated the highest accuracy of 86% in the experiment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=negative%20emotion" title="negative emotion">negative emotion</a>, <a href="https://publications.waset.org/abstracts/search?q=emotion%20detection" title=" emotion detection"> emotion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media%20filtering%20sentiment%20analysis" title=" social media filtering sentiment analysis"> social media filtering sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning." title=" deep learning."> deep learning.</a> </p> <a href="https://publications.waset.org/abstracts/191945/automatic-detection-and-filtering-of-negative-emotion-bearing-contents-from-social-media-in-amharic-using-sentiment-analysis-and-deep-learning-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191945.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">23</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">54</span> Design and Modeling of Light Duty Trencher</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yegetaneh%20T.%20Dejenu">Yegetaneh T.

Now a day due to civilization, the needs of the human being become endless, and the living condition becomes sophisticated. The unbalance between the needs and resource obligates them to find the way to manage this condition. The attempt to use the scares resource in very efficient and effective way makes the trench an endeavor practice in the world in all countries. A trencher is a construction equipment used to dig trenches, especially for laying pipes or cables, installing drainage, irrigation, installing fencing, and in preparation for trench warfare. It is a machine used to make a ditch by cutting the soil ground and effectively used in agricultural irrigation. The most common types of trencher are wheel trencher, chain trencher, micro trencher, portable trencher. In Ethiopia people have been trenching the ditch for many purposes and the tools they are using are Pickaxe, Shovel and some are using Micro Excavators. The adverse effect of using traditional equipment is, time and energy consuming, less productive, difficult and more man power is required. Hence it is necessary to design and produce low price, and simple machine to narrow this gap. Our objective is to design and model a light duty trencher that is used for trenching the ground or soil for making ditch and used for agricultural, ground cabling, ground piping, and drainage system. The designed machine trenches, maximum of 1-meter depth, 30 cm width, and the required length. The working mechanism is fully hydraulic, and the engine with 12.7 hp will provide suitable power for the pump that delivers 23 l/min at 1500 rpm to drive hydraulic motors and actuators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulics" title="hydraulics">hydraulics</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=trenching" title=" trenching"> trenching</a>, <a href="https://publications.waset.org/abstracts/search?q=ditch" title=" ditch"> ditch</a> </p> <a href="https://publications.waset.org/abstracts/61094/design-and-modeling-of-light-duty-trencher" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61094.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">215</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">53</span> Pathogen Identification of Fusarium Spp. And Chemotypes Associated With Wheat Crown Rot in Hebei Province of China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kahsay%20Tadesse%20Mawcha">Kahsay Tadesse Mawcha</a>, <a href="https://publications.waset.org/abstracts/search?q=Na%20Zhang"> Na Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Yiying"> Xu Yiying</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Jiaying"> Chang Jiaying</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenxiang%20Yang"> Wenxiang Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fusarium crown rot (FCR) diseased wheat seedlings were collected from different wheat-growing counties in seven different regions (Baoding, Cangzhou, Handan, Hengshui, Langfang, Shijiazhuang, and Xingtai) in Hebei province, China from 2019 to 2020. One-hundred twenty-two Fusarium isolates were isolated from crown rot diseased wheat seedlings and identified morphologically, confirmation was undertaken molecularly, and species-specific PCR was utilized to verify the morphological identification of F. psuedograminearum, F. graminearum, F. asiaticum, and F. culmorum. The predominant Fusarium species associated with wheat crown rot in the Hebei province were F. psuedograminearum, F. graminearum, F. asiaticum, and F. culmorum with isolation frequency of 85.25%, 12.30%, 1.64%, and 0.81%, respectively. All the Fusarium strains isolated from the different wheat-growing fields were qualitatively tested for toxigenic chemotypes using toxin-specific primers and chemotaxonomically classified into DON, 3-ADON, 15-ADON, and NIV. Among F. psuedograminearum identified, 84.62% were classified as DON chemotypes, 6.73% as 15-ADON chemotypes, 3.84% as 3-ADON chemotypes, and 4.81% of them had NIV as detected by the toxin-specific PCR results. Most of the F. graminearum isolates produced 15-ADON, and only two isolates had NIV chemotypes. F. asiaticum and F. culmorum produce chemotype of 15-ADON and 3-ADON, respectively. Pathogenicity test results showed that F. pseudograminearum and F. graminearum had strong pathogenicity, and F. asiaticum and F. culmorum had moderate pathogenicity to wheat in Hebei province. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crown%20rot" title="crown rot">crown rot</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogen" title=" pathogen"> pathogen</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat" title=" wheat"> wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusarium%20species" title=" Fusarium species"> Fusarium species</a>, <a href="https://publications.waset.org/abstracts/search?q=mycotoxin" title=" mycotoxin"> mycotoxin</a> </p> <a href="https://publications.waset.org/abstracts/150188/pathogen-identification-of-fusarium-spp-and-chemotypes-associated-with-wheat-crown-rot-in-hebei-province-of-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150188.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">135</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">52</span> Quantitative Analysis of Caffeine in Pharmaceutical Formulations Using a Cost-Effective Electrochemical Sensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20T.%20Gebreslassie">Y.

Given its widespread use in coffee and other caffeine-containing products, it is the most commonly consumed psychoactive substance in everyday human life. This research aimed to develop a cost-effective, sensitive, and easily manufacturable sensor for the detection of caffeine. Antraquinone-modified carbon paste electrode (AQMCPE) was fabricated, and the electrochemical behavior of caffeine on this electrode was investigated using cyclic voltammetry (CV) and square wave voltammetry (SWV) in a solution of 0.1M perchloric acid at pH 0.56. The modified electrode displayed enhanced electrocatalytic activity towards caffeine oxidation, exhibiting a two-fold increase in peak current and an 82 mV shift of the peak potential in the negative direction compared to an unmodified carbon paste electrode (UMCPE). Exploiting the electrocatalytic properties of the modified electrode, SWV was employed for the quantitative determination of caffeine. Under optimized experimental conditions, a linear relationship between peak current and concentration was observed within the range of 2.0 x 10⁻⁶ to 1.0× 10⁻⁴ M, with a correlation coefficient of 0.998 and a detection limit of 1.47× 10⁻⁷ M (signal-to-noise ratio = 3). Finally, the proposed method was successfully applied to the quantitative analysis of caffeine in pharmaceutical formulations, yielding recovery percentages ranging from 95.27% to 106.75%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antraquinone-modified%20carbon%20paste%20electrode" title="antraquinone-modified carbon paste electrode">antraquinone-modified carbon paste electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=caffeine" title=" caffeine"> caffeine</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20sensor" title=" electrochemical sensor"> electrochemical sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20analysis" title=" quantitative analysis"> quantitative analysis</a> </p> <a href="https://publications.waset.org/abstracts/180289/quantitative-analysis-of-caffeine-in-pharmaceutical-formulations-using-a-cost-effective-electrochemical-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180289.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">65</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">51</span> The Abundance and Distribution of Locally Important Species Along Different Altitude: The Case of Mountain Damota, Wolaita South Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamirat%20Solomon">Tamirat Solomon</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadesse%20Faltamo"> Tadesse Faltamo</a>, <a href="https://publications.waset.org/abstracts/search?q=Belete%20Limani"> Belete Limani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted on the mountain Damota of Wolaita to assess the abundance and spatial distribution of two locally important indigenous medicinal plants on the mountain landscape. A total of 130 plots measuring 20x20m were established along eight systematically laid transect lines. In each plot, the abundance and distribution of Hagenia abyssinica (tree) and Pentas schiperiana Vatke (shrub) were evaluated. The abundance and distribution of H. abyssinica were evaluated by measuring height and DBH for mature trees and counting seedlings and saplings, whereas the P. schiperiana Vatke was assessed for its abundance and distribution by counting in each plot. In the entire study plots, a total of 485 H. abyssinica and 760 P. schiperiana vatake were recorded. It was observed that the distribution of the species increased while the altitude increased and the highest abundance of the species was recorded at an altitude range between 2332 and 2661m.a.s.l. However, at the altitudes below 2320 m.a.s.l., the species distributions and abundance was decreased, indicating either the ecological preference of the species or the extraction of the local community surrounding the mountain influenced the species. On average, only 28 seedlings/ha of H. abyssinica and 146/ha of P. schiperiana vatke were recorded in the study areas showing the tendency of decline in the abundance and distribution of both species. Finally, we recommend management intervention for the socially important species which are under threat on the mountain landscape. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indigenous%20medicinal%20plants" title="indigenous medicinal plants">indigenous medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=H.abyssinic" title=" H.abyssinic"> H.abyssinic</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20schiperiana" title=" P. schiperiana"> P. schiperiana</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=abundance" title=" abundance"> abundance</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-economic%20importance" title=" socio-economic importance"> socio-economic importance</a> </p> <a href="https://publications.waset.org/abstracts/148075/the-abundance-and-distribution-of-locally-important-species-along-different-altitude-the-case-of-mountain-damota-wolaita-south-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148075.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">122</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">50</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.

Many physicochemical parameters (Mg²⁺, Na⁺, Ca²⁺, K⁺, CO₃-, SO4²⁻, HCO₃⁻, Cl⁻, TH, EC, TDS and pH) were analyzed following standard procedures. Different irrigation indices (MAR, SSP, SAR, RSC, KR, and PI) were also used for SGW suitability assessment. If all SGW are blended and used for irrigation, the salinity problem would be slight to moderate, and 100% of potential sugarcane yield could be obtained. The infiltration and sodium ion toxicity problems of the blended water would be none to moderate, and slight to moderate, respectively. As sugarcane is semi-tolerant to sodium toxicity, no significant sodium toxicity problem would be expected from the use of blended water. Blending SGW would also reduce each chloride and boron ion toxicity to none. In general, the rating of SGW was good to excellent for irrigation in terms of average EC (salinity), and excellent in terms of average SAR (infiltration). The SGW of the WSSE was categorized under C3S1 (high salinity and low sodium hazard). In conclusion, the conjunctive use of groundwater for irrigation would help to reduce the potential effect of waterlogging and salinization and their associated problems on soil and sugarcane production and productivity. However, a high value of SSP and RSC indicate a high possibility of infiltration problem. Hence, it is advisable to use the SGW for irrigation after blending with surface water. In this case, the optimum blending ratio of the surface to SGW sources has to be determined for sustainable sugarcane productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blending" title="blending">blending</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration" title=" infiltration"> infiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=sodicity" title=" sodicity"> sodicity</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane" title=" sugarcane"> sugarcane</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a> </p> <a href="https://publications.waset.org/abstracts/81841/conjunctive-use-of-shallow-groundwater-for-irrigation-purpose-the-case-of-wonji-shoa-sugar-estate-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81841.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">382</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">48</span> Sustainable Production of Tin Oxide Nanoparticles: Exploring Synthesis Techniques, Formation Mechanisms, and Versatile Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yemane%20Tadesse%20Gebreslassie">Yemane Tadesse Gebreslassie</a>, <a href="https://publications.waset.org/abstracts/search?q=Henok%20Gidey%20Gebretnsae"> Henok Gidey Gebretnsae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanotechnology has emerged as a highly promising field of research with wide-ranging applications across various scientific disciplines. In recent years, tin oxide has garnered significant attention due to its intriguing properties, particularly when synthesized in the nanoscale range. While numerous physical and chemical methods exist for producing tin oxide nanoparticles, these approaches tend to be costly, energy-intensive, and involve the use of toxic chemicals. Given the growing concerns regarding human health and environmental impact, there has been a shift towards developing cost-effective and environmentally friendly processes for tin oxide nanoparticle synthesis. Green synthesis methods utilizing biological entities such as plant extracts, bacteria, and natural biomolecules have shown promise in successfully producing tin oxide nanoparticles. However, scaling up the production to an industrial level using green synthesis approaches remains challenging due to the complexity of biological substrates, which hinders the elucidation of reaction mechanisms and formation processes. Thus, this review aims to provide an overview of the various sources of biological entities and methodologies employed in the green synthesis of tin oxide nanoparticles, as well as their impact on nanoparticle properties. Furthermore, this research delves into the strides made in comprehending the mechanisms behind the formation of nanoparticles as documented in existing literature. It also sheds light on the array of analytical techniques employed to investigate and elucidate the characteristics of these minuscule particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title="nanotechnology">nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=tin%20oxide" title=" tin oxide"> tin oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20synthesis" title=" green synthesis"> green synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=formation%20mechanisms" title=" formation mechanisms"> formation mechanisms</a> </p> <a href="https://publications.waset.org/abstracts/182340/sustainable-production-of-tin-oxide-nanoparticles-exploring-synthesis-techniques-formation-mechanisms-and-versatile-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182340.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">53</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">47</span> Genetic Trait Analysis of RIL Barley Genotypes to Sort-out the Top Ranked Elites for Advanced Yield Breeding Across Multi Environments of Tigray, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hailekiros%20Tadesse%20Tekle">Hailekiros Tadesse Tekle</a>, <a href="https://publications.waset.org/abstracts/search?q=Yemane%20Tsehaye"> Yemane Tsehaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Fetien%20Abay"> Fetien Abay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Barley (Hordeum vulgare L.) is one of the most important cereal crops in the world, grown for the poor farmers in Tigray with low yield production. The purpose of this research was to estimate the performance of 166 barley genotypes against the quantitative traits with detailed analysis of the variance component, heritability, genetic advance, and genetic usefulness parameters. The finding of ANOVA was highly significant variation (p ≤ 0:01) for all the genotypes. We found significant differences in coefficient of variance (CV of 15%) for 5 traits out of the 12 quantitative traits. The topmost broad sense heritability (H2) was recorded for seeds per spike (98.8%), followed by thousand seed weight (96.5%) with 79.16% and 56.25%, respectively, of GAM. The traits with H2 ≥ 60% and GA/GAM ≥ 20% suggested the least influenced by the environment, governed by the additive genes and direct selection for improvement of such beneficial traits for the studied genotypes. Hence, the 20 outstanding recombinant inbred lines (RIL) barley genotypes performing early maturity, high yield, and 1000 seed weight traits simultaneously were the top ranked group barley genotypes out of the 166 genotypes. These are; G5, G25, G33, G118, G36, G123, G28, G34, G14, G10, G3, G13, G11, G32, G8, G39, G23, G30, G37, and G26. They were early in maturity, high TSW and GYP (TSW ≥ 55 g, GYP ≥ 15.22 g/plant, and DTM below 106 days). In general, the 166 genotypes were classified as high (group 1), medium (group 2), and low yield production (group 3) genotypes in terms of yield and yield component trait analysis by clustering; and genotype parameter analysis such as the heritability, genetic advance, and genetic usefulness traits in this investigation. <p class="card-text"><strong>Keywords:</strong> <a
