Some plants which were accumulated extremely elements, are called indicator plants. In this study, the 11 plant species and soil samples were collected boron deposits area in Kirka (Eskisehir). Boron is determinated in plants (leaves and twigs) and soil samples. Additionally, statistical relations were established between the B values of plant and soil samples and three plants were only found. The boron in twigs of Puccinellia intermedia (n = 17, r = 0.7274), twigs of Genista aucheri (n = 26, r = 0.8581 and leaves of Pinus nigra (n = 16, r = 0.6805) species are found 119, 81 and 115 mg/kg respectively. This species was reflected boron in soil and their used indicator plant for boron. The indicator plants could be successfully used for biogeochemical prospecting and environmental monitoring.展开更多

In addition, flood elevation effects of Porsuk River in Eskişehir city and the regions around were investigated. Necessary data for study were obtained from Eskişehir 3. Regional Directorate of State Hydraulic Works archives. For analyses, the cross section of Porsuk River was defined in the Hydrologic Engineering Centers River Analysis System (HEC-RAS) software. Subsequently, recurring periods of 50, 100 and 1000 years discharge of Porsuk River which is calculated as 51.83 m3/s, 60.15 m3/s and 86.66 m3/s respectively were inputted in the software to obtain analysis results. Obtained results from the present study and topographic data were compared and interpreted. As a result, elevation of flood and its risks for urban regions were studied and presented.展开更多

The decision of surgical priority can change according to the severity of the coronary artery disease or carotid artery disease at staged surgery. The aim of the study is to compare the outcomes of simultaneous surgery (CEA + CABG) and CABG alone at our department. Materials and Methods: We retrospectively reviewed the CABG and CEA + CABG patients which were performed between 2010 and 2015. If the patients had simultaneous another operation, they were excluded from the study. A total of 294 patients (252 CABG patients and 42 combined surgery patients), were retrospectively examined. Results: Two patients in CABG group and two patients in CABG + CEA group developed stroke. There was no statistically significant difference between the two groups in terms of early stroke rate (p > 0.05). One patient in CEA + CABG group and three patients in CABG group died. The average carotid clamp time was 19.93 ± 5.06 minutes. Aortic clamp times were 42.89 ± 6.38 minutes in CABG and 42.81 ± 5.70 minutes in CEA + CABG patients. Results of the two groups were similar. Conclusion: Combined CEA and CABG can be performed successfully and safely in patients.展开更多
