Such hydrologic changes will affect almost every aspect of human well-being. The goal of this paper is to assess the impact of climate change on the hydrology of Upper Guder catchment located in northwest of Ethiopia. The GCM derived scenarios (HadCM3 A2a & B2a SRES emission scenarios) experiments were used for the climate projection. The statistical downscaling model (SDSM) was used to generate future possible local meteorological variables in the study area. The down-scaled data were then used as input to the soil and water assessment tool (SWAT) model to simulate the corresponding future stream flow regime in Upper Guder catchment of the Abay River Basin. A semi distributed hydrological model, SWAT was developed and Generalized Likelihood Uncertainty Estimation (GLUE) was utilized for uncertainty analysis. GLUE is linked with SWAT in the Calibration and Uncertainty Program known as SWAT-CUP. Three benchmark periods simulated for this study were 2020s, 2050s and 2080s. The time series generated by GCM of HadCM3 A2a and B2a and Statistical Downscaling Model (SDSM) indicate a significant increasing trend in maximum and minimum temperature values and a slight increasing trend in precipitation for both A2a and B2a emission scenarios in both Gedo and Tikur Inch stations for all three bench mark periods. The hydrologic impact analysis made with the downscaled temperature and precipitation time series as input to the hydrological model SWAT suggested for both A2a and B2a emission scenarios. The model output shows that there may be an annual increase in flow volume up to 35% for both emission scenarios in three benchmark periods in the future. All seasons show an increase in flow volume for both A2a and B2a emission scenarios for all time horizons. Potential evapotranspiration in the catchment also will increase annually on average 3-15% for the 2020s and 7-25% for the 2050s and 2080s for both A2a and B2a emissions scenarios. <p class="card-text"><strong>Keywords:</strong> <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=Guder%20sub-basin" title=" Guder sub-basin"> Guder sub-basin</a>, <a href="https://publications.waset.org/abstracts/search?q=GCM" title=" GCM"> GCM</a>, <a href="https://publications.waset.org/abstracts/search?q=SDSM" title=" SDSM"> SDSM</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT" title=" SWAT"> SWAT</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT-CUP" title=" SWAT-CUP"> SWAT-CUP</a>, <a href="https://publications.waset.org/abstracts/search?q=GLUE" title=" GLUE"> GLUE</a> </p> <a href="https://publications.waset.org/abstracts/6237/assessment-of-climate-change-impacts-on-the-hydrology-of-upper-guder-catchment-upper-blue-nile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6237.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">364</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> Religious Discrimination Against Small Business Owners: Evidence from the 1875 Cadastral Survey of Istanbul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20Unveren">Burak Unveren</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecem%20Uygun"> Ecem Uygun</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zdemi%CC%87r%20Teke"> Özdemi̇r Teke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A large body of literature documents how the Ottoman Empire's economic decline in relation to Western Europe was exacerbated by the unequal legal treatment of its subjects based on creed. Motivated by this debate, we empirically explore whether property taxes collected from businesses in Istanbul discriminated against or favored non-Muslims after the cadastral survey of the capital in 1875. The survey was conducted to determine the property taxes. And the process was potentially susceptible to the biased views of the surveyors who calculated the taxes payable via their subjective appraisals of all real properties. According to our results, in contrast to widely held beliefs regarding 19th-century Istanbul, the number of Muslim shop owners is higher than that of non-Muslims. Moreover, we find evidence for taxes collected from non-Muslim shop and store owners to be higher compared to Muslims, even after controlling for all physical features (e.g., size, location, etc.). These results directly pertain to the fiscal capacity of the Ottoman state and its economic divergence from Europe in the 19th century. Surprisingly, the data also indicates no statistically different tax differentials between male and female property owners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20history" title="economic history">economic history</a>, <a href="https://publications.waset.org/abstracts/search?q=taxation" title=" taxation"> taxation</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20business" title=" small business"> small business</a>, <a href="https://publications.waset.org/abstracts/search?q=discrimination" title=" discrimination"> discrimination</a> </p> <a href="https://publications.waset.org/abstracts/162895/religious-discrimination-against-small-business-owners-evidence-from-the-1875-cadastral-survey-of-istanbul" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Geophysical Mapping of the Groundwater Aquifer System in Gode Area, Northeastern Hosanna, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esubalew%20Yehualaw%20Melaku">Esubalew Yehualaw Melaku</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, two basic geophysical methods are applied for mapping the groundwater aquifer system in the Gode area along the Guder River, northeast of Hosanna town, near the western margin of the Central Main Ethiopian Rift.

The occurrence of Moyamoya disease is related to immune, genetic and other factors. There is no curative treatment for Moyamoya disease. Secondary prevention for patients with symptomatic Moyamoya disease is largely centered on surgical revascularization techniques. We present here a 62-year old male presented with headache and vision loss for 2 days. He was previously diagnosed with hypertension and glaucoma. On physical examination, left eye movements were restricted medially, both eyes were hyperemic and their movements were painful. Other neurological and physical examination were normal. His vital signs and laboratory results were within normal limits. Computed tomography (CT) showed dilated vascular structures around both lateral ventricles and atherosclerotic changes inside the walls of internal carotid artery (ICA). Magnetic resonance imaging (MRI) and angiography (MRA) revealed dilated venous vascular structures around lateral ventricles and hyper-intense gliosis in periventricular white matter. Ischemic gliosis around the lateral ventricles were present in the Digital Subtracted Angiography (DSA). After the neurology, ophthalmology and neurosurgery consultation, the patient was diagnosed with Moyamoya disease, pulse steroid therapy was started for vision loss, and super-selective DSA was planned for further investigation. Moyamoya disease is a rare condition, but it can be an important cause of stroke in both children and adults. It generally affects anterior circulation, but posterior cerebral circulation may also be affected, as well. In the differential diagnosis of acute vision loss, occipital stroke related to Moyamoya disease should be considered. Direct and indirect surgical revascularization surgeries may be used to effectively revascularize affected brain areas, and have been shown to reduce risk of stroke. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=headache" title="headache">headache</a>, <a href="https://publications.waset.org/abstracts/search?q=Moyamoya%20disease" title=" Moyamoya disease"> Moyamoya disease</a>, <a href="https://publications.waset.org/abstracts/search?q=stroke" title=" stroke"> stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20loss" title=" visual loss"> visual loss</a> </p> <a href="https://publications.waset.org/abstracts/73630/rare-diagnosis-in-emergency-room-moyamoya-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73630.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">267</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> Lipid Emulsion versus DigiFab in a Rat Model of Acute Digoxin Toxicity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cansu%20Arslan%20Turan">Cansu Arslan Turan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuba%20Cimilli%20Ozturk"> Tuba Cimilli Ozturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebru%20Unal%20Akoglu"> Ebru Unal Akoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Aygun"> Kemal Aygun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecem%20Deniz%20K%C4%B1rkpantur"> Ecem Deniz Kırkpantur</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozge%20Ecmel%20Onur"> Ozge Ecmel Onur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although the mechanism of action is not well known, Intravenous Lipid Emulsion (ILE) has been shown to be effective in the treatment of lipophilic drug intoxications. It is thought that ILE probably separate the lipophilic drugs from target tissue by creating a lipid-rich compartment in the plasma. The second theory is that ILE provides energy to myocardium with high dose free fatty acids activating the voltage gated calcium channels in the myocytes. In this study, the effects of ILE treatment on digoxin overdose which are frequently observed in emergency departments was searched in an animal model in terms of cardiac side effects and survival. The study was carried out at Yeditepe University, Faculty of Medicine-Experimental Animals Research Center Labs in December 2015. 40 Sprague-Dawley rats weighing 300-400 g were divided into 5 groups randomly. As the pre-treatment, the first group received saline, the second group received lipid, the third group received DigiFab, and the fourth group received DigiFab and lipid. Following that, digoxin was infused to all groups until death except the control group. First arrhythmia and cardiac arrest occurrence times were recorded. As no medication causing arrhythmia was infused, Group 5 was excluded from the statistical analysis performed for the comparisons of first arrhythmia and death time. According to the results although there was no significant difference in the statistical analysis comparing the four groups, as the rats, only exposed to digoxin intoxication were compared with the rats pre-treated with ILE in terms of first arrhythmia time and cardiac arrest occurrence times, significant difference was observed between the groups. According to our results, using DigiFab treatment, intralipid treatment, intralipid and DigiFab treatment for the rats exposed to digoxin intoxication makes no significant difference in terms of the first arrhythmia and death occurrence time. However, it is not possible to say that at the doses we use in the study, ILE treatment might be successful at least as a known antidote. The fact that the statistical significance between the two groups is not observed in the inter-comparisons of all the groups, the study should be repeated in the larger groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arrhytmia" title="arrhytmia">arrhytmia</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20arrest" title=" cardiac arrest"> cardiac arrest</a>, <a href="https://publications.waset.org/abstracts/search?q=DigiFab" title=" DigiFab"> DigiFab</a>, <a href="https://publications.waset.org/abstracts/search?q=digoxin%20intoxication" title=" digoxin intoxication"> digoxin intoxication</a> </p> <a href="https://publications.waset.org/abstracts/73758/lipid-emulsion-versus-digifab-in-a-rat-model-of-acute-digoxin-toxicity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73758.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">234</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> Epigastric Pain in Emergency Room: Median Arcuate Ligament Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Demet%20Devrimsel%20Dogan">Demet Devrimsel Dogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecem%20Deniz%20Kirkpantur"> Ecem Deniz Kirkpantur</a>, <a href="https://publications.waset.org/abstracts/search?q=Muharrem%20Dogan"> Muharrem Dogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Aykut"> Ahmet Aykut</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebru%20Unal%20Akoglu"> Ebru Unal Akoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozge%20Ecmel%20Onur"> Ozge Ecmel Onur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Median Arcuate Ligament Syndrome (MALS) is a rare cause of chronic abdominal pain due to external compression of the celiac trunk by a fibrous arch that unites diaphragmatic crura on each side of the aortic hiatus. While 10-24% of the population may suffer from compression of celiac trunk, it rarely causes patients to develop symptoms. The typical clinical triad of symptoms includes postprandial epigastric pain, weight loss and vomiting. The diagnosis can be made using thin section multi-detector computed tomography (CT) scans which delineate the ligament and the compressed vessel. The treatment of MALS is aimed at relieving the compression of the celiac artery to restore adequate blood flow through the vessel and neurolysis to address chronic pain. Case: A 68-year-old male presented to our clinic with acute postprandial epigastric pain. This was patients’ first attack, and the pain was the worst pain of his life. The patient did not have any other symptoms like nausea, vomiting, chest pain or dyspnea. In his medical history, the patient has had an ischemic cerebrovascular stroke 5 years ago which he recovered with no sequel, and he was using 75 mg clopidogrel and 100 mg acetylsalicylic acid. He was not using any other medication and did not have a story of cardiovascular disease. His vital signs were stable (BP:113/72 mmHg, Spo2:97, temperature:36.3°C, HR:90/bpm). In his electrocardiogram, there was ST depression in leads II, III and AVF. In his physical examination, there was only epigastric tenderness, other system examinations were normal. Physical examination through his upper gastrointestinal system showed no bleeding. His laboratory results were as follows: creatinine:1.26 mg/dL, AST:42 U/L, ALT:17 U/L, amylase:78 U/L, lipase:26 U/L, troponin:10.3 pg/ml, WBC:28.9 K/uL, Hgb:12.7 gr/dL, Plt:335 K/uL. His serial high-sensitive troponin levels were also within normal limits, his echocardiography showed no segmental wall motion abnormalities, an acute myocardial infarction was excluded. In his abdominal ultrasound, no pathology was founded. Contrast-enhanced abdominal CT and CT angiography reported ‘thickened diaphragmatic cruras are compressing and stenosing truncus celiacus superior, this is likely compatible with MALS’. The patient was consulted to general surgery, and they admitted the patient for laparoscopic ligament release. Results: MALS is a syndrome that causes postprandial pain, nausea and vomiting as its most common symptoms. Affected patients are normally young, slim women between the ages of 30 and 50 who have undergone extensive examinations to find the source of their symptoms. To diagnose MALS, other underlying pathologies should initially be excluded. The gold standard is aortic angiography. Although diagnosis and treatment of MALS are unclear, symptom resolution has been achieved with multiple surgical modalities, including open, laparoscopic or robotic ligament release as well as celiac ganglionectomy, which often requires celiac artery revascularisation. <p class="card-text"><strong>Keywords:</strong> <a
