Use of infrared thermometry for developing baseline equations and scheduling irrigation in wheat

This study was conducted to develop baseline equations, which can be used to quantify crop water stress index (CWSI) for evaluating crop water stress in three winter wheat genotypes (Triticum aestivum L.) and to schedule irrigation and predict yield. Plants were grown under basin irrigation and subjected to five water treatments ranging from 100 to 0 (100, 75, 50, 25, 0 %) replacement of evapotranspirational losses within 0.90 m soil profile. The highest yield and water use was obtained under fully irrigated conditions (100 replenishment of soil water depleted). The lower (non-stressed) and upper (stressed) baselines were determined empirically from measurements of canopy and ambient air temperatures and vapour pressure deficit (VPD) on fully watered plants (100%) and under maximum water stress (0 %), respectively. The CWSI was determined by using the empirical approach for the five irrigation levels. The yield was directly correlated with the mean CWSI values and the linear equation for three genotypes (Saraybosna, Kate-A-1 and F-85), Y = 1463.3 - 1062.3 CWSI, Y = 1483.8 - 1052.8 CWSI and Y = 1701.8 - 1367.7 CWSI can be used for the yield prediction. CWSI values may also provide a valuable tool for monitoring water status and planning irrigation scheduling for wheat

Borderline ovarian tumors: A study of 100 cases

15069 Background: The purpose of the study was to evaluate the patients with borderline ovarian tumors. Methods: Clinical features, treatment and survival status of 100 patients with borderline ovarian tumors were retrospectively evaluated between 1998 and 2005. Results: Mean age was 37.75 (Range: 15–72) years. 22 cases were in postmenapausal status. Histopathological diagnosis was serous, musinous, endometrioid and clear cell in 54%, 41%, 2%, 3% of the patients, respectively. 19 cases underwent restaging laparotomy. In 52 cases fertility sparing surgery was performed. 70 patients had stage IA, 8 patients had stage IB, 16 cases had stage IC, 2 cases had stage IIIA, 3 cases cases had stage IIIB and a case had stage IIIC disease. 22 cases were administered chemotherapy because of advanced stage disease. All cases were alive. 5 year disease free survival of 51 cases was 100%. Conclusions: Borderline ovarian tumors have excellent prognosis and conservative surgery can be performed in young patients with early stage disease.
