In this study, it is aimed to develop the flood risk analysis of Porsuk River, which is responsible for naming of the Porsuk Basin sub basin of Sakarya Basin, by utilizing the methods of Remote Sensing (RS) and Geographical Information Systems (GIS). 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.

作者： turgut zis Imail Aslan Department of Mathematics Ege University Department of Mathematics Izmir Institute of Technology

With the aid of symbolic computation system Mathematica, several explicit solutions for Fisher＇s equation and CKdV equation are constructed by utilizing an auxiliary equation method, the so called G′/G-expansion method, where the new and more general forms of solutions are also constructed. When the parameters are taken as special values, the previously known solutions are recovered.

Influences of Pr and Ta doping concentration on the characteristic features of FTO thin film deposited by spray pyrolysis

引用

Chinese Physics B 2015年第10期24卷 414-422页

作者： Güven turgut Adem Koqyigit Erdal Snmez Erzurum Technical University Science FacultyDepartment of Basic Sciences Igdir University Engineering FacultyDepartment of Electrical Electronic Engineering Ataturk University Kazim Karabekir Education FacultyDepartment of Physics

The Pr and Ta separately doped FTO（10 at.% F incorporated Sn O2） films are fabricated via spray pyrolysis. The microstructural, topographic, optical, and electrical features of fluorine-doped TO（FTO） films are investigated as functions of Pr and Ta dopant concentrations. The x-ray diffraction（XRD） measurements reveal that all deposited films show polycrystalline tin oxide crystal property. FTO film has（200） preferential orientation, but this orientation changes to（211） direction with Pr and Ta doping ratio increasing. Atomic force microscopy（AFM） and scanning electron microscopy（SEM） analyses show that all films have uniform and homogenous nanoparticle distributions. Furthermore, morphologies of the films depend on the ratio between Pr and Ta dopants. From ultraviolet-visible（UV-Vis） spectrophotometer measurements, it is shown that the transmittance value of FTO film decreases with Pr and Ta doping elements increasing. The band gap value of FTO film increases only at 1 at.% Ta doping level, it drops off with Pr and Ta doping ratio increasing at other doped FTO films. The electrical measurements indicate that the sheet resistance value of FTO film initially decreases with Pr and Ta doping ratio decreasing and then it increases with Pr and Ta doping ratio increasing. The highest value of figure of merit is obtained for 1 at.% Ta- and Pr-doped FTO film. These results suggest that Pr- and Ta-doped FTO films may be appealing candidates for TCO applications.

作者： Mete Güler turgut Yìlmaz Department of Ophthalmology School of Medicine Adiyaman University Department of Ophthalmology School of MedicineInnü University

AIM:To describe the results of vitrectomy and partial capsulectomy via anterior approach surgical technique in treatment of chronic postoperative endophthalmitis (CPE). METHODS:Clinical records of 9 patients treated for CPE between 2006 and 2010 were reviewed retrospectively. All of these patients were treated with vitrectomy and partial capsulectomy via anterior approach. RESULTS:Six of 9 patients were male. The average patients’ age was (60 ±8.1) years. The average period between cataract extraction and onset of signs and symptoms was (3.6±1.3) weeks. The average presenting visual acuity was 0.3 ±0.1 and the average final post operative visual acuity was 0.7±0.2. The mean follow-up period was (28.1±8.9) weeks. In all patients, the inflammation subsided after surgery. · CONCLUSION:Our results suggest that anterior vitrectomy and partial capsulectomy via anterior approach may be considered as potentially useful and relatively less invasive technique to treat CPE.

Cultural schema and design activity in an architectural design studio

引用

Frontiers of Architectural Research 2017年第2期6卷 183-203页

作者： Gokce Ketizmen Onal Hulya turgut Eskisehir Osmangazi University Department of Architecture Bademlik Campus Odunpazari-Eskisehir Turkey Ozyegin University Faculty of Architecture and Design Department of Architecture Nisantepe Mah. Orman Sok. Cekmekoy 34794 Istanbul Turkey

Research on the cognitive activities and on the structure and quality of knowledge flow involved in architectural design education is increasing. These studies generally focus on the interaction between student and instructor, including processes such as producing ideas, solving display problems, and integrating design strategies. These studies commonly include computational evaluations and confirmation of the coding of knowledge. They may also include the determination of designer＇s thoughts and cognitive actions of design process, as welt as the analysis and digitization of verbal protocols during the design process. In most of these studies, the designer＇s cultural and psychological components are not considered. Accordingly, research on the effects of designers＇ cultural schema on design activity in design studios is limited. This study aimed to solve this problem by analyzing the relationship between design activity and the designer＇s cultural schema in a design studio. We performed an experimental study based on a specific conceptual framework and a research model aimed at identifying the relationships among cultural schemas, the architectural design process, and design studios.
