    Determination of potential flooding of inebolu basin by cn method with a gis-based software
    (Institute of Electrical and Electronics Engineers Inc., 2019) Katmerlikaya S.; Kurucak G.; Dabanli A.; Kocamaz A.F.; Sarica O.O.; Dogan A.; Baltaci E.
    Inaccurate planning and methods of land cover / use occurring in the basins increase the intensity and frequency of flood events. The fact that floods are predictable before they occur is of great importance for preventive activities. Therefore, modeling of the basin; plays an important role in planning and developing local resources. In this study, flooding in İnebolu basin of Kastamonu province is modeled. In this context, GIS-based, flexible and user-friendly grid-based software is developed. Surface water retention capacity and the amount of water flowing on the surface were calculated for each grid. Thus, flood formation areas could be determined in the region where the study was carried out. © 2019 IEEE.

    Context: Spectroscopic imaging can be helpful to identify metabolite changes in a normal appearing brain parenchyma after MR imaging in patients with lung cancer. Aims: To detect metabolic changes in the cerebellar and cerebral normal appearing white matter with single-voxel H-MR spectroscopy (MRS) in patients with lung cancer. Methods and material: MRS was performed in the Cerebellar White Matter (CWM) and Parietal White Matter (PWM) of patients with lung cancer (n=38; age range: 44-82 y; mean age: 66.1 ± 8.7) and an age-matched control group (n=32; age range: 42-80 y; mean age: 62.9 ± 8). Biopsies of lung masses showed 25 Non-Small Cell Lung Cancer (NSCLC) and 13 Small Cell Lung Cancer (SCLC). NAA/Cr, NAA/Cho and Cho/Cr ratios were calculated. Statistical analysis used: The unpaired-t test was used for the assessment of metabolite ratio differences between patients and control subjects. Mann-Whitney U test was used among SCLC, NSCLC, and control group for the evaluation of metabolite ratio differences. Results: The Cho/Cr ratios in the CWM were significantly lower in the patients compared to controls (p=0.03). The Cho/Cr ratio of patients with SCLC was significantly lower in PWM than both NSCLC (p=0.02) and control group (p=0.03). Conclusion: Decreased Cho/Cr ratio possibly represents increased uptake of Cho or reduced brain function. These results may be important in assessing patients with lung cancer in order to help with treatment planning and prognosis. © 2017, Scientific Publishers of India, All rights reserved.
