Abstract

The prediction of hydrological drought is significant for the management of water resources, planning of hydroelectricity production, agricultural production, habitat, and life of living things. The primary aim of this study is to increase the prediction success hydrological drought in the Wadi Ouahrane basin (270 km2). For this purpose, support vector regression technique is hybridized with Election Algorithm. Standardized Runoff Index (SRI) values were used to determine hydrological droughts. In calculating droughts, rainfall and stream flow data covering the years 1972–2018 were employed. Standardized Precipitation Index (SPI) and previous SRI values were used in the establishment of the hydrological drought prediction model. The coefficient of determination, Standard deviation, the Akaike information criterion and root-mean-square error values were used to test the model accuracy. It was identified to be the most accurate according to the research outputs were obtained with SRI-12 and the Election Algorithm-based support vector regression algorithm showed successful results in hydrological drought prediction. In addition, it was revealed that realistic results are obtained when SPI value and delayed SRI values were used as inputs in multi-time scale analysis of hydrological drought.

Abstract

Background: Peptic ulcer is a sore in the protective lining (mucosal lining) of the gastrointestinal tract and develops when the lining is damaged. The objectives of this Descriptive Validational study were to determine the validity of Barium Meal examination in the diagnosis of peptic ulcer disease in comparison to the gold standard, i.e., endoscopic evaluation in peptic ulcer disease. The study was conducted at Radiology Department Khyber Teaching Hospital Peshawar from November 2000 to March 2004., Methods: A total of 115 patients with signs and symptoms of peptic ulcer disease were selected for this study and were subjected for this diagnostic modality. The diagnosis of benign/malignant peptic ulcer was made by barium meal examinations. In all these patients the diagnosis was later on confirmed by endoscopy and or surgery., Results: Of the 115 patients, 80 were male and 35 were female patients. Their ages ranged from 27-75 years with mean age of 49 years. Fifty two patients had duodenal ulcer, 30 patients gastric ulcer, and 33 patients had normal radiological findings. In 6 out of 30 patients with gastric ulcer had radiological evidence of malignant gastric ulcer., Conclusion: Efficiency of Barium meal examination in diagnosis of peptic ulcer is good and most of peptic ulcers can be diagnosed by this method.

Abstract

Background: To determine the impact of Cervical Cerclage (CC) for prolongation of pregnancy, maternal and foetal outcome., Methods: This Descriptive cross-sectional study was conducted over a period of 2 years patients with history of two or more recurrent midtrimester abortions/preterm deliveries were included. Those with abnormal foetus, vaginal bleeding and choreoamneonitis were excluded. All patients were subjected to transvaginal sonography. Those having sonographic evidence of cervical shortening/dilatation/cone formation were subjected to McDonald suture. Age, parity, period of gestation and aetiological factors were determined., Results: Results were evaluated on the basis of pregnancy prolongation, 14-28 weeks (7.5%), 28-36 weeks (18.7%), 35-37 weeks (73.7%),vaginal delivery in (70%), instrumental (1305%), Caesarean section (17.5%),miscarriage (7.5%), prematurity (18.7%), term delivery (73.7%), prenatal death (13.7%), foetal survival rate (85.1%). No intraoperative complication found. During pregnancy premature rupture of membrane (3.7%), abruption (2.5%), severe pre-eclampsia (3.7%). During labour cervical dystocia was found in (2.5%), foetal distress (8.7%), mal-presentations (6.2%), cervical trauma (3.7%)., Conclusion: We determined a high success rate of cervical cerclage on properly selected patients with sonographic evidence of cervical changes. Cervical sonography can be a valuable adjunct to clinical evaluation of these patients.
