<p class="card-text"><strong>Abstract:</strong></p> Perovskite-based gas sensors represent a highly promising materials within the realm of gas sensing technology, with a particular focus on detecting ammonia (NH3) due to its potential hazards. Our work conducted thorough comparison of various solvents, including dimethylformamide (DMF), DMF-dimethyl sulfoxide (DMSO), dimethylacetamide (DMAC), and DMAC-DMSO, for the preparation of our perovskite solution (MAPbI3). Significantly, we achieved an exceptional response at 10 ppm of ammonia gas by employing a binary solvent mixture of DMAC-DMSO. In contrast to prior reports that relied on single solvents for MAPbI3 precursor preparation, our approach using mixed solvents demonstrated a marked improvement in gas sensing performance. We attained enhanced surface coverage, a reduction in pinhole occurrences, and precise control over grain size in our perovskite films through the careful selection and mixtures of appropriate solvents. This study shows a promising potential of employing binary and multi-solvent mixture strategies as a means to propel advancements in gas sensor technology, opening up new opportunities for practical applications in environmental monitoring and industrial safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sensors" title="sensors">sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20solvents" title=" binary solvents"> binary solvents</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia" title=" ammonia"> ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20size" title=" grain size"> grain size</a>, <a href="https://publications.waset.org/abstracts/search?q=pinholes" title=" pinholes"> pinholes</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20coverage" title=" surface coverage"> surface coverage</a> </p> <a href="https://publications.waset.org/abstracts/175863/breaking-sensitivity-barriers-perovskite-based-gas-sensors-with-dimethylacetamide-dimethyl-sulfoxide-solvent-mixture-strategy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175863.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">107</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">20</span> Optical Variability of Faint Quasars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kassa%20Endalamaw%20Rewnu">Kassa Endalamaw Rewnu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The variability properties of a quasar sample, spectroscopically complete to magnitude J = 22.0, are investigated on a time baseline of 2 years using three different photometric bands (U, J and F). The original sample was obtained using a combination of different selection criteria: colors, slitless spectroscopy and variability, based on a time baseline of 1 yr. The main goals of this work are two-fold: first, to derive the percentage of variable quasars on a relatively short time baseline; secondly, to search for new quasar candidates missed by the other selection criteria; and, thus, to estimate the completeness of the spectroscopic sample. In order to achieve these goals, we have extracted all the candidate variable objects from a sample of about 1800 stellar or quasi-stellar objects with limiting magnitude J = 22.50 over an area of about 0.50 deg2. We find that > 65% of all the objects selected as possible variables are either confirmed quasars or quasar candidates on the basis of their colors. This percentage increases even further if we exclude from our lists of variable candidates a number of objects equal to that expected on the basis of `contamination' induced by our photometric errors. The percentage of variable quasars in the spectroscopic sample is also high, reaching about 50%. On the basis of these results, we can estimate that the incompleteness of the original spectroscopic sample is < 12%. We conclude that variability analysis of data with small photometric errors can be successfully used as an efficient and independent (or at least auxiliary) selection method in quasar surveys, even when the time baseline is relatively short. Finally, when corrected for the different intrinsic time lags corresponding to a fixed observed time baseline, our data do not show a statistically significant correlation between variability and either absolute luminosity or redshift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nuclear%20activity" title="nuclear activity">nuclear activity</a>, <a href="https://publications.waset.org/abstracts/search?q=galaxies" title=" galaxies"> galaxies</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20quasars" title=" active quasars"> active quasars</a>, <a href="https://publications.waset.org/abstracts/search?q=variability" title=" variability"> variability</a> </p> <a href="https://publications.waset.org/abstracts/166872/optical-variability-of-faint-quasars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166872.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">19</span> Assessment of the Contribution of Geographic Information System Technology in Non Revenue Water: Case Study Dar Es Salaam Water and Sewerage Authority Kawe - Mzimuni Street</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Pesco%20Kassa">Victor Pesco Kassa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research deals with the assessment of the contribution of GIS Technology in NRW. This research was conducted at Dar, Kawe Mzimuni Street. The data collection was obtained from existing source which is DAWASA HQ. The interpretation of the data was processed by using ArcGIS software. The data collected from the existing source reveals a good coverage of DAWASA’s water network at Mzimuni Street. Most of residents are connected to the DAWASA’s customer service. Also the collected data revealed that by using GIS DAWASA’s customer Geodatabase has been improved. Through GIS we can prepare customer location map purposely for site surveying also this map will be able to show different type of customer that are connected to DAWASA’s water service. This is a perfect contribution of the GIS Technology to address and manage the problem of NRW in DAWASA. Finally, the study recommends that the same study should be conducted in other DAWASA’s zones such as Temeke, Boko and Bagamoyo not only at Kawe Mzimuni Street. Through this study it is observed that ArcGIS software can offer powerful tools for managing and processing information geographically and in water and sanitation authorities such as DAWASA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DAWASA" title="DAWASA">DAWASA</a>, <a href="https://publications.waset.org/abstracts/search?q=NRW" title=" NRW"> NRW</a>, <a href="https://publications.waset.org/abstracts/search?q=Esri" title=" Esri"> Esri</a>, <a href="https://publications.waset.org/abstracts/search?q=EURA" title=" EURA"> EURA</a>, <a href="https://publications.waset.org/abstracts/search?q=ArcGIS" title=" ArcGIS"> ArcGIS</a> </p> <a href="https://publications.waset.org/abstracts/164374/assessment-of-the-contribution-of-geographic-information-system-technology-in-non-revenue-water-case-study-dar-es-salaam-water-and-sewerage-authority-kawe-mzimuni-street" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164374.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">83</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> Electrochemical Treatment and Chemical Analyses of Tannery Wastewater Using Sacrificial Aluminum Electrode, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dessie%20Tibebe">Dessie Tibebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Muluken%20Asmare"> Muluken Asmare</a>, <a href="https://publications.waset.org/abstracts/search?q=Marye%20Mulugeta"> Marye Mulugeta</a>, <a href="https://publications.waset.org/abstracts/search?q=Yezbie%20Kassa"> Yezbie Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Zerubabel%20Moges"> Zerubabel Moges</a>, <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Yenealem"> Dereje Yenealem</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarekegn%20Fentie"> Tarekegn Fentie</a>, <a href="https://publications.waset.org/abstracts/search?q=Agmas%20Amare"> Agmas Amare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The performance of electrocoagulation (EC) using Aluminium electrodes for the treatment of effluent-containing chromium metal using a ﬁxed bed electrochemical batch reactor was studied. In the present work, the efficiency evaluation of EC in removing physicochemical and heavy metals from real industrial tannery wastewater in the Amhara region, collected from Bahirdar, Debre Brihan, and Haik, was investigated. The treated and untreated samples were determined by AAS and ICP OES spectrophotometers. The results indicated that selected heavy metals were removed in all experiments with high removal percentages. The optimal results were obtained regarding both cost and electrocoagulation efficiency with initial pH = 3, initial concentration = 40 mg/L, electrolysis time = 30 min, current density = 40 mA/cm2, and temperature = 25oC favored metal removal. The maximum removal percentages of selected metals obtained were 84.42% for Haik, 92.64% for Bahir Dar and 94.90% for Debre Brihan. The sacrificial electrode and sludge were characterized by FT-IR, SEM and XRD. After treatment, some metals like chromium will be used again as a tanning agent in leather processing to promote a circular economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical" title="electrochemical">electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum" title=" aluminum"> aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=tannery%20effluent" title=" tannery effluent"> tannery effluent</a> </p> <a href="https://publications.waset.org/abstracts/174363/electrochemical-treatment-and-chemical-analyses-of-tannery-wastewater-using-sacrificial-aluminum-electrode-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174363.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">110</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> MATLAB Supported Learning and Students' Conceptual Understanding of Functions of Two Variables: Experiences from Wolkite University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eyasu%20Gemech">Eyasu Gemech</a>, <a href="https://publications.waset.org/abstracts/search?q=Kassa%20Michael"> Kassa Michael</a>, <a href="https://publications.waset.org/abstracts/search?q=Mulugeta%20Atnafu"> Mulugeta Atnafu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A non-equivalent group's quasi-experiment research was conducted at Wolkite University to investigate MATLAB supported learning and students' conceptual understanding in learning Applied Mathematics II using four different comparative instructional approaches: MATLAB supported traditional lecture method, MATLAB supported collaborative method, only collaborative method, and only traditional lecture method. Four intact classes of mechanical engineering groups 1 and 2, garment engineering and textile engineering students were randomly selected out of eight departments. The first three departments were considered as treatment groups and the fourth one 'Textile engineering' was assigned as a comparison group. The departments had 30, 29, 35 and 32 students respectively. The results of the study show that there is a significant mean difference in students' conceptual understanding between groups of students learning through MATLAB supported collaborative method and the other learning approaches. Students who were learned through MATLAB technology-supported learning in combination with collaborative method were found to understand concepts of functions of two variables better than students learning through the other methods of learning. These, hence, are informative of the potential approaches universities would follow for a better students’ understanding of concepts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MATLAB%20supported%20collaborative%20method" title="MATLAB supported collaborative method">MATLAB supported collaborative method</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB%20supported%20learning" title=" MATLAB supported learning"> MATLAB supported learning</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20method" title=" collaborative method"> collaborative method</a>, <a href="https://publications.waset.org/abstracts/search?q=conceptual%20understanding" title=" conceptual understanding"> conceptual understanding</a>, <a href="https://publications.waset.org/abstracts/search?q=functions%20of%20two%20variables" title=" functions of two variables"> functions of two variables</a> </p> <a href="https://publications.waset.org/abstracts/93374/matlab-supported-learning-and-students-conceptual-understanding-of-functions-of-two-variables-experiences-from-wolkite-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93374.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">278</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> Treatment and Characterization of Cadmium Metal From Textile Factory Wastewater by Electrochemical Process Using Aluminum Plate Electrode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dessie%20Tibebe">Dessie Tibebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeshifana%20Ayenew"> Yeshifana Ayenew</a>, <a href="https://publications.waset.org/abstracts/search?q=Marye%20Mulugeta"> Marye Mulugeta</a>, <a href="https://publications.waset.org/abstracts/search?q=Yezbie%20Kassa"> Yezbie Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Zerubabel%20Moges"> Zerubabel Moges</a>, <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Yenealem"> Dereje Yenealem</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarekegn%20Fentie"> Tarekegn Fentie</a>, <a href="https://publications.waset.org/abstracts/search?q=Agmas%20Amare"> Agmas Amare</a>, <a href="https://publications.waset.org/abstracts/search?q=Hailu%20Sheferaw%20Ayele"> Hailu Sheferaw Ayele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrochemical treatment technology is a technique used for wastewater treatment due to its ability to eliminate impurities that are not easily removed by chemical processes. The objective of the study is the treatment and characterization of textile wastewater by an electrochemical process. The results obtained at various operational parameters indicated that at 20 minutes of electrochemical process at ( pH =7), initial concentration 10 mg/L, current density 37.5 mA/cm², voltage 9 v and temperature 25⁰C the highest removal efficiency was achieved. The kinetics of removal of selected metal by electrochemical treatment has been successfully described by the first-order rate equation. The results of microscopic techniques using SEM for the scarified electrode before treatment were uniform and smooth, but after the electrochemical process, the morphology was completely changed. This is due to the detection of the adsorbed aluminum hydroxide coming from adsorption of the conducting electrolyte, chemicals used in the experiments, alloying and the scrap impurities of the anode and cathode. The FTIR spectroscopic analysis broad bands at 3450 cm-¹ representing O-H functional groups, while the presence of H-O-H and Al-H groups are indicated by the bands at 2850-2750 cm-¹ and 1099 representing C-H functional groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical" title="electrochemical">electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20wastewater" title=" textile wastewater"> textile wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=removal%20efficiency" title=" removal efficiency"> removal efficiency</a> </p> <a href="https://publications.waset.org/abstracts/174364/treatment-and-characterization-of-cadmium-metal-from-textile-factory-wastewater-by-electrochemical-process-using-aluminum-plate-electrode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174364.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">97</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">15</span> Poly (Diphenylamine-4-Sulfonic Acid) Modified Glassy Carbon Electrode for Voltammetric Determination of Gallic Acid in Honey and Peanut Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Bitew">Zelalem Bitew</a>, <a href="https://publications.waset.org/abstracts/search?q=Adane%20Kassa"> Adane Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Beyene%20Misgan"> Beyene Misgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a sensitive and selective voltammetric method based on poly(diphenylamine-4-sulfonic acid) modified glassy carbon electrode (poly(DPASA)/GCE) was developed for determination of gallic acid.

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">14</span> A Study of Basic and Reactive Dyes Removal from Synthetic and Industrial Wastewater by Electrocoagulation Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Almaz%20Negash">Almaz Negash</a>, <a href="https://publications.waset.org/abstracts/search?q=Dessie%20Tibebe"> Dessie Tibebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Marye%20Mulugeta"> Marye Mulugeta</a>, <a href="https://publications.waset.org/abstracts/search?q=Yezbie%20Kassa"> Yezbie Kassa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Large-scale textile industries use large amounts of toxic chemicals, which are very hazardous to human health and environmental sustainability. In this study, the removal of various dyes from effluents of textile industries using the electrocoagulation process was investigated. The studied dyes were Reactive Red 120 (RR-120), Basic Blue 3 (BB-3), and Basic Red 46 (BR-46), which were found in samples collected from effluents of three major textile factories in the Amhara region, Ethiopia. For maximum removal, the dye BB-3 required an acidic pH 3, RR120 basic pH 11, while BR-46 neutral pH 7 conditions. BB-3 required a longer treatment time of 80 min than BR46 and RR-120, which required 30 and 40 min, respectively. The best removal efficiency of 99.5%, 93.5%, and 96.3% was achieved for BR-46, BB-3, and RR-120, respectively, from synthetic wastewater containing 10 mg L1of each dye at an applied potential of 10 V. The method was applied to real textile wastewaters and 73.0 to 99.5% removal of the dyes was achieved, Indicating Electrocoagulation can be used as a simple, and reliable method for the treatment of real wastewater from textile industries. It is used as a potentially viable and inexpensive tool for the treatment of textile dyes. Analysis of the electrochemically generated sludge by X-ray Diffraction, Scanning Electron Microscope, and Fourier Transform Infrared Spectroscopy revealed the expected crystalline aluminum oxides (bayerite (Al(OH)3 diaspore (AlO(OH)) found in the sludge. The amorphous phase was also found in the floc. Textile industry owners should be aware of the impact of the discharge of effluents on the Ecosystem and should use the investigated electrocoagulation method for effluent treatment before discharging into the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title="electrocoagulation">electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20electrodes" title=" aluminum electrodes"> aluminum electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=Basic%20Blue%203" title=" Basic Blue 3"> Basic Blue 3</a>, <a href="https://publications.waset.org/abstracts/search?q=Basic%20Red%2046" title=" Basic Red 46"> Basic Red 46</a>, <a href="https://publications.waset.org/abstracts/search?q=Reactive%20Red%20120" title=" Reactive Red 120"> Reactive Red 120</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20industry" title=" textile industry"> textile industry</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/174229/a-study-of-basic-and-reactive-dyes-removal-from-synthetic-and-industrial-wastewater-by-electrocoagulation-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174229.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">13</span> Drug Susceptibility and Genotypic Assessment of Mycobacterial Isolates from Pulmonary Tuberculosis Patients in North East Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minwuyelet%20Maru">Minwuyelet Maru</a>, <a href="https://publications.waset.org/abstracts/search?q=Solomon%20Habtemariam"> Solomon Habtemariam</a>, <a href="https://publications.waset.org/abstracts/search?q=Endalamaw%20Gadissa"> Endalamaw Gadissa</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Aseffa"> Abraham Aseffa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Tuberculosis is a major public health problem in Ethiopia. The burden of TB is aggravated by emergence and expansion of drug resistant tuberculosis and different lineages of Mycobacterium tuberculosis (M. tuberculosis) have been reported in many parts of the country. Describing strains of Mycobacterial isolates and drug susceptibility pattern is necessary. Method: Sputum samples were collected from smear positive pulmonary TB patients age >= 7 years between October 1, 2012 to September 30, 2013 and Mycobacterial strains isolated on Loweensten Jensen (LJ) media. Each strain was characterized by deletion typing and Spoligotyping. Drug sensitivity testing was determined with the indirect proportion method using Middle brook 7H10 media and association to determine possible risk factors to drug resistance was done. Result: A total of 144 smear positive pulmonary tuberculosis patients were enrolled. The age of participants ranged from 7 to 78 with mean age of 29.22 (±10.77) years. In this study 82.2% (n=97) of the isolates were sensitive to the four first line anti-tuberculosis drugs and resistance to any of the four drugs tested was 17.8% (n=21). A high frequency of any resistance was observed in isoniazid, 13.6%, (n=16) followed by streptomycin, 11.8% (n=14). No significant association of isoniazid resistance with HIV, sex and history of previous TB treatment was observed but there was significant association with age, high between 31-35 years of age (p=0.01). Majority, 89.9% (n=128) of participants were new cases and only 11.1% (n=16) had history of previous TB treatment. No MDR-TB from new cases and 2 MDRTB (13.3%) was isolated from re-treatment cases which was significantly associated with previous TB treatment (p<0.01). Thirty two different types of spoligotype patterns were identified and 74.1% were grouped in to 13 clusters. The dominant strains were SIT 25, 18.1% (n=21), SIT 53, 17.2% (n=20) and SIT 149, 8.6% (n=10). Lineage 4 is the predominant lineage followed by lineage 3 and lineage 7 comprising 65.5% (n=76), 28.4% (n=33) and 6% (n=7) respectively. Majority of strains from lineage 3 and 4 were SIT 25 (63.6%) and SIT 53 (26.3%) whereas SIT 343 was the dominant strain from lineage 7 (71.4%). Conclusion: Wide spread of lineage 3 and lineage 4 of the modern lineage and high number of strain cluster indicates high ongoing transmission. The high proportion resistance to any of the first line anti-tuberculosis drugs may be a potential source in the emergence of MDR-TB. Wide spread of SIT 25 and SIT 53 having a tendency of ease transmission and presence of higher resistance of isoniazid in working and mobile age group, 31-35 years of age may increase risk of drug resistant strains transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title="tuberculosis">tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20susceptibility" title=" drug susceptibility"> drug susceptibility</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20diversity" title=" strain diversity"> strain diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=lineage" title=" lineage"> lineage</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=spoligotyping" title=" spoligotyping "> spoligotyping </a> </p> <a href="https://publications.waset.org/abstracts/8015/drug-susceptibility-and-genotypic-assessment-of-mycobacterial-isolates-from-pulmonary-tuberculosis-patients-in-north-east-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8015.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">375</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> Seroprevalence of Bovine Brucellosis and its Public Health Significance in Selected Sites of Central High Land of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temesgen%20Kassa%20Getahun">Temesgen Kassa Getahun</a>, <a href="https://publications.waset.org/abstracts/search?q=Gezahegn%20Mamo"> Gezahegn Mamo</a>, <a href="https://publications.waset.org/abstracts/search?q=Beksisa%20Urge"> Beksisa Urge</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A cross-sectional study was conducted from December 2019 to May 2020 with the aim of determining the seroprevalence of brucellosis in dairy cows and their owners in the central highland of Oromia, Ethiopia. A total of 352 blood samples from dairy cattle, 149 from animal owners, and 17 from farm workers were collected and initially screened using the Rose Bengal Plate test and confirmed by the Complement Fixation test. Overall seroprevalence was 0.6% (95% CI: 0.0016–0.0209) in bovines and 1.2% (95% CI: 0.0032–0.0427) in humans. Market-based stock replacement (OR=16.55, p=0.002), breeding by artificial insemination (OR=7.58, p=0.05), and parturition pen (OR = 11.511, p=0.027) were found to be significantly associated with the seropositivity for Brucella infection in dairy cattle. Human housing (OR=1.8, p=0.002), contact with an aborted fetus (OR=21.19, p=0.017), drinking raw milk from non-aborted (OR=24.99, p=0.012), aborted (OR=5.72, p=0.019) and retained fetal membrane (OR=4.22, p=0.029) cows had a significant influence on human brucellosis. A structured interview question was administered to 284 respondents. Accordingly, most respondents had no knowledge of brucellosis (93.3%), and in contrast, 90% of them consumed raw milk. In conclusion, the present seroprevalence study revealed that brucellosis was low among dairy cattle and exposed individuals in the study areas. However, since there were no control strategies implemented in the study areas, there is a potential risk of transmission of brucellosis in dairy cattle and the exposed human population in the study areas. Implementation of a test and slaughter strategy with compensation to farmers is recommended, while in the case of human brucellosis, continuous social training and implementing one health approach framework must be applied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abortion" title="abortion">abortion</a>, <a href="https://publications.waset.org/abstracts/search?q=bovine%20brucellosis" title=" bovine brucellosis"> bovine brucellosis</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20brucellosis" title=" human brucellosis"> human brucellosis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=seroprevalence" title=" seroprevalence"> seroprevalence</a> </p> <a href="https://publications.waset.org/abstracts/153754/seroprevalence-of-bovine-brucellosis-and-its-public-health-significance-in-selected-sites-of-central-high-land-of-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153754.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">105</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> Estimation Atmospheric parameters for Weather Study and Forecast over Equatorial Regions Using Ground-Based Global Position System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmamaw%20Yehun">Asmamaw Yehun</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegaye%20Kassa"> Tsegaye Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Addisu%20Hunegnaw"> Addisu Hunegnaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Vermeer"> Martin Vermeer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are various models to estimate the neutral atmospheric parameter values, such as in-suite and reanalysis datasets from numerical models. Accurate estimated values of the atmospheric parameters are useful for weather forecasting and, climate modeling and monitoring of climate change. Recently, Global Navigation Satellite System (GNSS) measurements have been applied for atmospheric sounding due to its robust data quality and wide horizontal and vertical coverage. The Global Positioning System (GPS) solutions that includes tropospheric parameters constitute a reliable set of data to be assimilated into climate models. The objective of this paper is, to estimate the neutral atmospheric parameters such as Wet Zenith Delay (WZD), Precipitable Water Vapour (PWV) and Total Zenith Delay (TZD) using six selected GPS stations in the equatorial regions, more precisely, the Ethiopian GPS stations from 2012 to 2015 observational data. Based on historic estimated GPS-derived values of PWV, we forecasted the PWV from 2015 to 2030. During data processing and analysis, we applied GAMIT-GLOBK software packages to estimate the atmospheric parameters. In the result, we found that the annual averaged minimum values of PWV are 9.72 mm for IISC and maximum 50.37 mm for BJCO stations. The annual averaged minimum values of WZD are 6 cm for IISC and maximum 31 cm for BDMT stations. In the long series of observations (from 2012 to 2015), we also found that there is a trend and cyclic patterns of WZD, PWV and TZD for all stations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmosphere" title="atmosphere">atmosphere</a>, <a href="https://publications.waset.org/abstracts/search?q=GNSS" title=" GNSS"> GNSS</a>, <a href="https://publications.waset.org/abstracts/search?q=neutral%20atmosphere" title=" neutral atmosphere"> neutral atmosphere</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitable%20water%20vapour" title=" precipitable water vapour"> precipitable water vapour</a> </p> <a href="https://publications.waset.org/abstracts/176074/estimation-atmospheric-parameters-for-weather-study-and-forecast-over-equatorial-regions-using-ground-based-global-position-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176074.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">61</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> Artificial Intelligence Techniques for Enhancing Supply Chain Resilience: A Systematic Literature Review, Holistic Framework, and Future Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adane%20Kassa%20Shikur">Adane Kassa Shikur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today’s supply chains (SC) have become vulnerable to unexpected and ever-intensifying disruptions from myriad sources. Consequently, the concept of supply chain resilience (SCRes) has become crucial to complement the conventional risk management paradigm, which has failed to cope with unexpected SC disruptions, resulting in severe consequences affecting SC performances and making business continuity questionable. Advancements in cutting-edge technologies like artificial intelligence (AI) and their potential to enhance SCRes by improving critical antecedents in the different phases have attracted the attention of scholars and practitioners. The research from academia and the practical interest of the industry have yielded significant publications at the nexus of AI and SCRes during the last two decades. However, the applications and examinations have been primarily conducted independently, and the extant literature is dispersed into research streams despite the complex nature of SCRes. To close this research gap, this study conducts a systematic literature review of 106 peer-reviewed articles by curating, synthesizing, and consolidating up-to-date literature and presents the state-of-the-art development from 2010 to 2022. Bayesian networks are the most topical ones among the 13 AI techniques evaluated. Concerning the critical antecedents, visibility is the first ranking to be realized by the techniques. The study revealed that AI techniques support only the first 3 phases of SCRes (readiness, response, and recovery), and readiness is the most popular one, while no evidence has been found for the growth phase. The study proposed an AI-SCRes framework to inform research and practice to approach SCRes holistically. It also provided implications for practice, policy, and theory as well as gaps for impactful future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANNs" title="ANNs">ANNs</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Bauesian%20networks" title=" Bauesian networks"> Bauesian networks</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/175934/artificial-intelligence-techniques-for-enhancing-supply-chain-resilience-a-systematic-literature-review-holistic-framework-and-future-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175934.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">95</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> Healthcare Professionals' Utilization of Physical Exercise as a Strategy to Prevent Non-Communicable Diseases in Ethiopian Public Sector Hospitals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeanne%20Grace">Jeanne Grace</a>, <a href="https://publications.waset.org/abstracts/search?q=Melkamu%20D.%20Kassa"> Melkamu D.

Objective: This study explored healthcare professionals’ use of physical exercise as a non-communicable disease prevention strategy in the Ethiopian public sector healthcare system. Methods: In this cross-sectional study, a self-administered questionnaire was conducted after being piloted to ensure validity and reliability. For the study, 312 participants were selected from 13 purposively selected Ethiopian referral hospitals, these being 99 physicians who were purposively selected and 213 nurses who were proportionately and randomly selected. Results: The results indicated that three-quarters (78%) of healthcare professionals working in Ethiopian hospitals are not using physical exercise as a strategy to prevent NCDs. Increased specialization (AOR = 20.203, p < 0.001), longer service years (AOR = 0.041, p = 0.014), young age (AOR = 19.871, p < 0.001), and being male (AOR = 0.269, p < 0.001), were predictors of using physical exercise as a strategy for the prevention of NCDs. Conclusion: Healthcare professionals’ utilization of physical exercise as a strategy for NCDs prevention was inadequate in Ethiopia. Given the increasing burden of NCD disease in Ethiopia, training nurses, physicians and medical managers have to acknowledge the use of physical exercise as an NCD prevention strategy. The results of this study highlight the importance of formulating physical exercise intervention strategies for NCDs patients, and the need to incorporate training for healthcare professionals on the type, intensity, duration, and frequency of physical exercise to prevent NCDs in the Ethiopian healthcare system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exercise" title="exercise">exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20managers" title=" medical managers"> medical managers</a>, <a href="https://publications.waset.org/abstracts/search?q=nurses" title=" nurses"> nurses</a>, <a href="https://publications.waset.org/abstracts/search?q=physicians" title=" physicians"> physicians</a> </p> <a href="https://publications.waset.org/abstracts/95035/healthcare-professionals-utilization-of-physical-exercise-as-a-strategy-to-prevent-non-communicable-diseases-in-ethiopian-public-sector-hospitals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95035.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">174</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> Effect of Temperature on Investigation of Index Properties of Red Clay Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Birhanu%20Kassa">Birhanu Kassa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The knowledge of temperature effect on index properties and, thus, the understanding of its behavior may be essential for a complete understanding of the various cases of Geotechnical Engineering problems and for conducting meaningful practical research, analysis, and design in tropical regions, such as the Ethiopian environment. The scarcity of the proper geotechnical information on the subsoil makes foundation and engineering works risk able, difficult, and sometimes hazardous. Seasonal variations, environmental effects, terrain challenges, and temperature effects all affect the quality of soil. Simada is a city which is found in south Gondar and it is developing rapidly both in horizontal and vertical construction. Rapid urbanization in the city area has led to an increased interest in the basic properties of soils that are present within the city area. There has been no previous research that looks into the effect of temperature on the investigation of clay soil index qualities in Simada. This work focuses mainly on investigating the Index and some other properties of soil in Simada Town with varying temperatures. To explore the influence of temperature change, samples were collected from various regions of the city, and routine laboratory tests were performed on the collected samples at various temperatures. Disturbed samples were taken at intervals where an average depth of 1.5-2m depths below natural ground level. The standard laboratory tests performed on all twenty-four soil samples were the water content, gradation analysis, Atterberg limits, specific gravity, and compaction test. All specimens were tested at different temperatures (25°C, 35 °C, 45 °C, 65 °C,75 and 105 °C). The variation of the plasticity characteristics of the soils has been determined based on the temperature variation. From the test result, we can conclude that temperature has a significant effect on the index properties of clay soil, in our case, red clay soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airdried" title="airdried">airdried</a>, <a href="https://publications.waset.org/abstracts/search?q=oven%20dried" title=" oven dried"> oven dried</a>, <a href="https://publications.waset.org/abstracts/search?q=soils%20index%20properties" title=" soils index properties"> soils index properties</a>, <a href="https://publications.waset.org/abstracts/search?q=compaction%20test" title=" compaction test"> compaction test</a> </p> <a href="https://publications.waset.org/abstracts/191946/effect-of-temperature-on-investigation-of-index-properties-of-red-clay-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191946.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">36</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> Prioritizing Forest Conservation Strategies Using a Multi-Attribute Decision Model to Address Concerns with the Survival of the Endangered Dragon Tree (Dracaena ombet Kotschy and Peyr.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfay%20Gidey">Tesfay Gidey</a>, <a href="https://publications.waset.org/abstracts/search?q=Emiru%20Birhane"> Emiru Birhane</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashenafi%20Manaye"> Ashenafi Manaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Hailemariam%20Kassa"> Hailemariam Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfay%20Atsbha"> Tesfay Atsbha</a>, <a href="https://publications.waset.org/abstracts/search?q=Negasi%20Solomon"> Negasi Solomon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadgu%20Hishe"> Hadgu Hishe</a>, <a href="https://publications.waset.org/abstracts/search?q=Aklilu%20Negussie"> Aklilu Negussie</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Madera"> Petr Madera</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20G.%20Borges"> Jose G.

Anthropogenic and natural factors are now impacting the sustainability of the species. This study was conducted to prioritize criteria and alternative strategies for the conservation of the species using the analytical hierarchy process (AHP) model by involving all relevant stakeholders in the Desa'a dry Afromontane forest in northern Ethiopia. Information about the potential alternative strategies and the criteria for their evaluation was first collected from experts, personal experiences, and literature reviews. Afterward, they were validated using stakeholders' focus group discussions. Five candidate strategies with three evaluation criteria were considered for prioritization using the AHP techniques. The overall priority ranking value of the stakeholders showed that the ecological criterion was deemed as the most essential factor for the choice of alternative strategies, followed by the economic and social criteria. The minimum cut-off strategy, combining exclosures with the collection of only 5% of plant parts from the species, soil and water conservation, and silviculture interventions, was selected as the best alternative strategy for sustainable D. ombet conservation. The livelihood losses due to the selected strategy should be compensated by the collection of non-timber forest products, poultry farming, home gardens, rearing small ruminants, beekeeping, and agroforestry. This approach may be extended to study other dragon tree species and explore strategies for the conservation of other arid ecosystems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation%20strategies" title="conservation strategies">conservation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process%20model" title=" analytical hierarchy process model"> analytical hierarchy process model</a>, <a href="https://publications.waset.org/abstracts/search?q=Desa%27a%20forest" title=" Desa'a forest"> Desa'a forest</a>, <a href="https://publications.waset.org/abstracts/search?q=endangered%20species" title=" endangered species"> endangered species</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=overexploitation" title=" overexploitation"> overexploitation</a> </p> <a href="https://publications.waset.org/abstracts/174113/prioritizing-forest-conservation-strategies-using-a-multi-attribute-decision-model-to-address-concerns-with-the-survival-of-the-endangered-dragon-tree-dracaena-ombet-kotschy-and-peyr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174113.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">93</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> Assessing the Survival Time of Hospitalized Patients in Eastern Ethiopia During 2019–2020 Using the Bayesian Approach: A Retrospective Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chalachew%20Gashu">Chalachew Gashu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoseph%20Kassa"> Yoseph Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Habtamu%20Geremew"> Habtamu Geremew</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengestie%20Mulugeta"> Mengestie Mulugeta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aims: Severe acute malnutrition remains a significant health challenge, particularly in low‐ and middle‐income countries. The aim of this study was to determine the survival time of under‐five children with severe acute malnutrition. Methods: A retrospective cohort study was conducted at a hospital, focusing on under‐five children with severe acute malnutrition. The study included 322 inpatients admitted to the Chiro hospital in Chiro, Ethiopia, between September 2019 and August 2020, whose data was obtained from medical records. Survival functions were analyzed using Kaplan‒Meier plots and log‐rank tests. The survival time of severe acute malnutrition was further analyzed using the Cox proportional hazards model and Bayesian parametric survival models, employing integrated nested Laplace approximation methods. Results: Among the 322 patients, 118 (36.6%) died as a result of severe acute malnutrition. The estimated median survival time for inpatients was found to be 2 weeks. Model selection criteria favored the Bayesian Weibull accelerated failure time model, which demonstrated that age, body temperature, pulse rate, nasogastric (NG) tube usage, hypoglycemia, anemia, diarrhea, dehydration, malaria, and pneumonia significantly influenced the survival time of severe acute malnutrition. Conclusions: This study revealed that children below 24 months, those with altered body temperature and pulse rate, NG tube usage, hypoglycemia, and comorbidities such as anemia, diarrhea, dehydration, malaria, and pneumonia had a shorter survival time when affected by severe acute malnutrition under the age of five. To reduce the death rate of children under 5 years of age, it is necessary to design community management for acute malnutrition to ensure early detection and improve access to and coverage for children who are malnourished. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20analysis" title="Bayesian analysis">Bayesian analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20acute%20malnutrition" title=" severe acute malnutrition"> severe acute malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=survival%20data%20analysis" title=" survival data analysis"> survival data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=survival%20time" title=" survival time"> survival time</a> </p> <a href="https://publications.waset.org/abstracts/186983/assessing-the-survival-time-of-hospitalized-patients-in-eastern-ethiopia-during-2019-2020-using-the-bayesian-approach-a-retrospective-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186983.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">47</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> Landslide Susceptibility Mapping Using Soft Computing in Amhara Saint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Semachew%20M.%20Kassa">Semachew M.

However, it is still difficult to select the most efficient method and correctly identify the main driving factors for particular regions. In this study, we used fourteen landslide conditioning factors (LCFs) and five soft computing algorithms, including Random Forest (RF), Support Vector Machine (SVM), Logistic Regression (LR), Artificial Neural Network (ANN), and Naïve Bayes (NB), to predict the landslide susceptibility at 12.5 m spatial scale. The performance of the RF (F1-score: 0.88, AUC: 0.94), ANN (F1-score: 0.85, AUC: 0.92), and SVM (F1-score: 0.82, AUC: 0.86) methods was significantly better than the LR (F1-score: 0.75, AUC: 0.76) and NB (F1-score: 0.73, AUC: 0.75) method, according to the classification results based on inventory landslide points. The findings also showed that around 35% of the study region was made up of places with high and very high landslide risk (susceptibility greater than 0.5). The very high-risk locations were primarily found in the western and southeastern regions, and all five models showed good agreement and similar geographic distribution patterns in landslide susceptibility. The towns with the highest landslide risk include Amhara Saint Town's western part, the Northern part, and St. Gebreal Church villages, with mean susceptibility values greater than 0.5. However, rainfall, distance to road, and slope were typically among the top leading factors for most villages. The primary contributing factors to landslide vulnerability were slightly varied for the five models. Decision-makers and policy planners can use the information from our study to make informed decisions and establish policies. It also suggests that various places should take different safeguards to reduce or prevent serious damage from landslide events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression" title=" logistic regression"> logistic regression</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide%20susceptibility" title=" landslide susceptibility"> landslide susceptibility</a>, <a href="https://publications.waset.org/abstracts/search?q=na%C3%AFve%20Bayes" title=" naïve Bayes"> naïve Bayes</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/174470/landslide-susceptibility-mapping-using-soft-computing-in-amhara-saint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174470.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">82</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> Impact of Climate Variability on Household's Crop Income in Central Highlands and Arssi Grain Plough Areas of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arega%20Shumetie%20Ademe">Arega Shumetie Ademe</a>, <a href="https://publications.waset.org/abstracts/search?q=Belay%20Kassa"> Belay Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Degye%20Goshu"> Degye Goshu</a>, <a href="https://publications.waset.org/abstracts/search?q=Majaliwa%20Mwanjalolo"> Majaliwa Mwanjalolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently the world economy is suffering from one critical problem, climate change. Some studies done before identified that impact of the problem is region specific means in some part of the world (temperate zone) there is improvement in agricultural performance but in some others like in the tropics there is drastic reduction in crop production and crop income. Climate variability is becoming dominant cause of short-term fluctuation in rain-fed agricultural production and income of developing countries. The purely rain-fed Ethiopian agriculture is the most vulnerable sector to the risks and impacts of climate variability. Thus, this study tried to identify impact of climate variability on crop income of smallholders in Ethiopia. The research used eight rounded unbalanced panel data from 1994- 2014 collected from six villages in the study area. After having all diagnostic tests the research used fixed effect method of regression. Based on the regression result rainfall and temperature deviation from their respective long term averages have negative and significant effect on crop income. Other extreme devastating shocks like flood, storm and frost, which are sourced from climate variability, have significant and negative effect on crop income of households’. Parameters that notify rainfall inconsistency like late start, variation in availability at growing season, and early cessation are critical problems for crop income of smallholder households as to the model result. Given this, impact of climate variability is not consistent in different agro-ecologies of the country. Rainfall variability has similar impact on crop income in different agro-ecology, but variation in temperature affects cold agro-ecology villages negatively and significantly, while it has positive effect in warm villages. Parameters that represent rainfall inconsistency have similar impact in both agro-ecologies and the aggregate model regression. This implies climate variability sourced from rainfall inconsistency is the main problem of Ethiopian agriculture especially the crop production sub-sector of smallholder households. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20variability" title="climate variability">climate variability</a>, <a href="https://publications.waset.org/abstracts/search?q=crop%20income" title=" crop income"> crop income</a>, <a href="https://publications.waset.org/abstracts/search?q=household" title=" household"> household</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfall" title=" rainfall"> rainfall</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/40264/impact-of-climate-variability-on-households-crop-income-in-central-highlands-and-arssi-grain-plough-areas-of-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40264.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">376</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> Identifying Controlling Factors for the Evolution of Shallow Groundwater Chemistry of Ellala Catchment, Northern Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grmay%20Kassa%20Brhane">Grmay Kassa Brhane</a>, <a href="https://publications.waset.org/abstracts/search?q=Hailemariam%20Siyum%20Mekonen"> Hailemariam Siyum Mekonen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was designed to identify the hydrogeochemical and anthropogenic processes controlling the evaluation of groundwater chemistry in the Ellala catchment which covers about 296.5 km2 areal extent. The chemical analysis revealed that the major ions in the groundwater are Ca2+, Mg2+, Na+, and K+ (cations) and HCO3-, PO43-, Cl-, NO3-, and SO42-(anions). Most of the groundwater samples (68.42%) revealed that the groundwater in the catchment is non-alkaline. In addition to the contribution of aquifer material, the solid materials and liquid wastes discharged from different sources can be the main sources of pH and EC in the groundwater. It is observed that the EC of the groundwater is fairly correlated with the DTS. This indicates that high mineralized water is more conductor than water with low concentration. The degree of salinity of the groundwater increases along the groundwater flow path from East to West; then, areas surrounding Mekelle City are highly saline due to the liquid and solid wastes discharged from the city and the industries. The groundwater facies in the catchment are predominated with calcium, magnesium, and bicarbonate which are labeled as Ca-Mg-HCO3 and Mg-Ca-HCO3. The main geochemical process controlling the evolution of the groundwater chemistry in the catchment is rock-water interaction, particularly carbonate dissolution. Due to the clay layer in the aquifer, the reverse is ion exchange. Non-significant silicate weathering and halite dissolution also contribute to the evolution of groundwater chemistry in the catchment. The groundwater in the catchment is dominated by the meteoritic origin although it needs further groundwater chemistry study with isotope dating analysis. The groundwater is under-saturated with calcite, dolomite, and aragonite minerals; hence, the more these minerals encounter the groundwater, the more the minerals dissolve. The main source of calcium and magnesium in groundwater is the dissolution of carbonate minerals (calcite and dolomite) since carbonate rocks are the dominant aquifer materials in the catchment. In addition to this, the weathering of dolerite rock is a possible source of magnesium ions. The relatively higher concentration of sodium over chloride indicates that the source of sodium-ion is reverse ion exchange and/or weathering of sodium-bearing materials, such as shale and dolerite rather than halite dissolution. High concentration of phosphate, nitrate, and chloride in the groundwater is the main anthropogenic source that needs treatment, quality control, and management in the catchment. From the Base Exchange Index Analysis, it is possible to understand that, in the catchment, the groundwater is dominated by the meteoritic origin, although it needs further groundwater chemistry study with isotope dating analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ellala%20catchment" title="Ellala catchment">Ellala catchment</a>, <a href="https://publications.waset.org/abstracts/search?q=factor" title=" factor"> factor</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemical" title=" geochemical"> geochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a> </p> <a href="https://publications.waset.org/abstracts/178488/identifying-controlling-factors-for-the-evolution-of-shallow-groundwater-chemistry-of-ellala-catchment-northern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178488.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">76</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> Implementing Quality Improvement Projects to Enhance Contraception and Abortion Care Service Provision and Pre-Service Training of Health Care Providers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munir%20Kassa">Munir Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengistu%20Hailemariam"> Mengistu Hailemariam</a>, <a href="https://publications.waset.org/abstracts/search?q=Meghan%20%20Obermeyer"> Meghan Obermeyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Kefelegn%20Baruda"> Kefelegn Baruda</a>, <a href="https://publications.waset.org/abstracts/search?q=Yonas%20Getachew"> Yonas Getachew</a>, <a href="https://publications.waset.org/abstracts/search?q=Asnakech%20Dessie"> Asnakech Dessie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improving the quality of sexual and reproductive health services that women receive is expected to have an impact on women’s satisfaction with the services, on their continued use and, ultimately, on their ability to achieve their fertility goals or reproductive intentions. Surprisingly, however, there is little empirical evidence of either whether this expectation is correct, or how best to improve service quality within sexual and reproductive health programs so that these impacts can be achieved. The Recent focus on quality has prompted more physicians to do quality improvement work, but often without the needed skill sets, which results in poorly conceived and ultimately unsuccessful improvement initiatives. As this renders the work unpublishable, it further impedes progress in the field of health care improvement and widens the quality chasm. Moreover, since 2014, the Center for International Reproductive Health Training (CIRHT) has worked diligently with 11 teaching hospitals across Ethiopia to increase access to contraception and abortion care services. This work has included improving pre-service training through education and curriculum development, expanding hands-on training to better learn critical techniques and counseling skills, and fostering a “team science” approach to research by encouraging scientific exploration. This is the first time this systematic approach has been applied and documented to improve access to high-quality services in Ethiopia. The purpose of this article is to report initiatives undertaken, and findings concluded by the clinical service team at CIRHT in an effort to provide a pragmatic approach to quality improvement projects. An audit containing nearly 300 questions about several aspects of patient care, including structure, process, and outcome indicators was completed by each teaching hospital’s quality improvement team. This baseline audit assisted in identifying major gaps and barriers, and each team was responsible for determining specific quality improvement aims and tasks to support change interventions using Shewart’s Cycle for Learning and Improvement (the Plan-Do-Study-Act model). To measure progress over time, quality improvement teams met biweekly and compiled monthly data for review. Also, site visits to each hospital were completed by the clinical service team to ensure monitoring and support. The results indicate that applying an evidence-based, participatory approach to quality improvement has the potential to increase the accessibility and quality of services in a short amount of time. In addition, continued ownership and on-site support are vital in promoting sustainability. This approach could be adapted and applied in similar contexts, particularly in other African countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abortion" title="abortion">abortion</a>, <a href="https://publications.waset.org/abstracts/search?q=contraception" title=" contraception"> contraception</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20improvement" title=" quality improvement"> quality improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20provision" title=" service provision"> service provision</a> </p> <a href="https://publications.waset.org/abstracts/78767/implementing-quality-improvement-projects-to-enhance-contraception-and-abortion-care-service-provision-and-pre-service-training-of-health-care-providers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78767.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">222</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> Nutrition Support Practices and Nutritional Status of Adolescents Receiving Antiretroviral Therapy in Selected Hospitals in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meless%20Gebrie%20Bore">Meless Gebrie Bore</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Perry"> Lin Perry</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyue%20Xu"> Xiaoyue Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Andargachew%20Kassa"> Andargachew Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Marilyn%20Cruickshank"> Marilyn Cruickshank</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Adolescents living with HIV (ALHIV) in Ethiopia face significant health challenges, particularly related to nutrition, which is essential for optimizing antiretroviral therapy (ART) outcomes. This population is vulnerable to nutritional deficiencies due to increased energy demands and the adverse effects of HIV, alongside rapid growth and low socio-economic status. Despite advances in ART, research on nutritional care for ALHIV in Ethiopia is limited. Integrated nutritional interventions are critical for improving health outcomes, yet comprehensive guidance is lacking. This study aimed to evaluate healthcare workers' practices in ART clinics, assess the nutritional status of ALHIV, and provide recommendations for enhancing nutritional care. Method: Cross-sectional surveys were conducted, recruiting 44 healthcare professionals and 384 ALHIV across ten public hospitals in Addis Ababa and Oromia regions. Participants were selected using purposive sampling for healthcare workers and proportionate random sampling for ALHIV engaged in ART services. Data was collected using a pre-tested structured questionnaire with quantitative and qualitative components facilitated by trained healthcare workers through the Kobo Toolbox program. Results: Findings revealed that while most healthcare workers conducted basic nutritional assessments, more sensitive methods were rarely used. Only 36.4% assessed dietary intake and 27.3% evaluated food security. Nutrition counseling was limited, with only 38.6% providing such services regularly. Health Care worker participants expressed dissatisfaction with the integration of nutrition services due to a lack of training and resources. Nutritional assessments revealed that 24.2% of ALHIV were classified as thin, 21.7% as stunted, and 34.9% as malnourished based on mid-upper arm circumference, with 19.4% experiencing severe acute malnutrition. These results highlight the urgent need and opportunities to improve nutritional support tailored to ALHIV-specific needs. Conclusion and Recommendations: Study findings identified evidence of substantial nutritional deficits and critical gaps in nutritional care for ALHIV in Ethiopian ART clinics. While basic assessment and counseling were generally practiced, limited use of more sensitive methods and inadequate integration of nutrition services hindered care effectiveness. To improve health outcomes, it is essential to enhance training for healthcare workers, develop standardized nutrition guidelines, and allocate resources effectively. Conducting further research with large, diverse samples and integrating comprehensive nutritional care alongside ART services will enable better matching of the nutritional needs of this vulnerable population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescents%20living%20with%20HIV%28ALHIV%29" title="adolescents living with
