    Effect of Deficit Irrigation Regimes on Yield and Fruit Quality of Olive Trees (cv. Memecik) on the Aegean Coast of Turkey
    (Wiley, 2017) Kaya, U.; Gungor, F. Ozturk; Camoglu, G.; Akkuzu, E.; Asik, S.; Koseoglu, O.
    In this study, six different irrigation treatments were applied to an olive orchard using the drip irrigation method. Five of these were arranged according to 25% (S-0.25), 50% (S-0.50), 75% (S-0.75), 100% (S-1.00) and 125% (S-1.25) of the evaporation in 5days of a class A' evaporation pan, and one control (S-C) was arranged so as to bring the reducing moisture at a soil depth of 0-90cm to field capacity. Yield values were not affected by the irrigation treatment (p>0.05). In contrast, 100-fruit weight, pulp ratio, hardness moisture, oil, reducing sugar content and bitterness were affected by irrigation (p<0.05). Generally, an increase in the amount of irrigation water given in the study was accompanied by a fall in ripeness index values, a rise in moisture content, and a reduction in the oil content of fruit. The highest content of reducing sugar was obtained from S-0.25, generally being lower with increase in the water applied. The findings show that application of 25% of the evaporation of a class A' evaporation pan (treatment S-0.25) can be recommended for cv. Memecik. Application of this recommendation can achieve a 72% saving in water and make a significant contribution to the conservation of limited water resources. Copyright (c) 2017 John Wiley & Sons, Ltd.

    Evaluation of CR-POSSUM, Original ACPGBI and New ACPGBI Scoring Systems for Colorectal Cancer Surgery
    (Editura Celsius, 2014) Ozkan, O. F.; Guner, A.; Kaya, U.; Kece, C.; Reis, E.; Kesici, S.
    Purpose: To compare the Colorectal Physiological and Operative Score for enUmeration of Mortality and Morbidity (Cr-POSSUM) with the original Association of Coloproctology of Great Britain and Ireland (ACPGBI) and new ACPGBI scoring systems for their ability to predict mortality after colorectal cancer surgery. Methods: We retrospectively calculated the Cr-POSSUM,original ACPBGI and new ACPGBI scores of 105 patients who underwent colorectal cancer surgery. Data were obtained from patients' medical records and operative notes.Mortality was defined as death within 30 days of surgery.Scores were validated by assessing their calibration and discrimination. Calibration was assessed using the Hosmer-Leme show test and corresponding calibration curves. The discriminative capability of the models was evaluated using receiver operating characteristic (ROC) curve analysis. Results: The observed mortality rate was 4.8 %. The over all estimated risks of death of the Cr-POSSUM, original ACPGBI, and new ACPGBI scores were 9.92%, 7.35% and 4.20%, respectively. The results of areas under the curve(AUC) for Cr-POSSUM, original ACPGBI and new ACPGBI scores were 0.792, 0.844 and 0.801 respectively. Conclusions: The Cr-POSSUM, original ACPGBI and new ACPGBI scoring syStems are accurate in determining mortality rates and for predicting the risks of death in individual patients. The new and original ACPGBI scoring systems performed slightly better than the Cr-POSSUM scoring system.
