reliability data update Method rdum based on living psa for emergency diesel generator of daya bay nuclear power plant
Safety Science, 2013Co-Authors: Muhammad Zubair, Zhang ZhijianAbstract:In the field of Living Probabilistic Safety Assessment (LPSA) the reliability data updating is an important factor. In risk analysis equipment failure data is needed to estimate the frequencies of events contributing to risk posed by a facility. Five years data of Emergency Diesel Generator (EDG) of Daya Bay Nuclear Power Plant (NPP) has been studied in this paper. The data updating process has been done by using two Methods (i.e.) Classical Method and Bayesian Method. The aim of using these Methods is to calculate operational failure rate (λ) and demand failure probability (p). The results show that operational failure rate is 1.7E−3 per hour and demand failure probability is 2.4E−2 per day of Daya Bay NPP. By comparing the results obtain from Classical and Bayesian Method with EDF (Electric De France) it is concluded that the design and construction of Daya Bay NPP is very different with EDF so reliability parameters used in Daya Bay NPP is based on Classical Method.

microscopic lesions of fallopian tubes in endometrioid carcinoma of the endometrium how effective are the macroscopic tubal sampling techniques
Journal of Gynecologic Oncology, 2013Co-Authors: Ibrahim Kulac, Alp UsubutunAbstract:OBJECTIVE: Extrauterine involvement of endometrial carcinoma has a significant effect on the patients' prognosis and treatment decision. In Classical Method, macroscopic section is taken from the fallopian tube sparing the fimbrial ends. Fimbrial end of fallopian tube may be involved by tumors and precursor lesions. This study aims to determine the importance of sampling of fimbrial ends of fallopian tube in endometrioid endometrial carcinoma specimens. MethodS: We reevaluated the fallopian tubes of 200 cases of endometrioid endometrial carcinoma cases that have no macroscopic tubal lesion. A hundred cases were sampled with Classical Method, and the other 100 were sampled with a new Method that includes the fimbrial ends. Statistical difference was examined by Fisher's exact test. RESULTS: No microscopic tubal lesion lesion was detected in cases that were sampled with the Classical Method. In contrast, there were 4 cases with tubal lesions in patients sampled with the new technique; 3 of them were located in the fimbrial end. Of the 3, there was one microscopic invasive carcinoma and two proliferative endometrial glandular lesions. Endometriosis was detected in two of the 4 cases with tubal lesions. CONCLUSION: Including the fimbrial end of fallopian tube to macroscopic sampling could detect more tubal lesions, which might provide additional prognostic and pathogenetic information of endometrioid endometrial carcinoma.

comparison of the Classical Method and see fim protocol in detecting microscopic lesions in fallopian tubes with gynecological lesions
Journal of pathology and translational medicine, 2018Co-Authors: Selcuk Ayas, Sevcan Arzu ArinkanAbstract:BACKGROUND: The objective of this study was to compare the Classical Method and Sectioning and Extensively Examining the Fimbriated End Protocol (SEE-FIM) in detecting microscopic lesions in fallopian tubes with gynecological lesions. MethodS: From a total of 1,118 cases, 582 with various parts of both fallopian tubes sampled in three-ring-shape sections and 536 sampled with the SEE-FIM protocol were included in this study. Pathological findings of cases with endometrial carcinoma, non-uterine pelvic malignant tumor, ovarian borderline tumors, premalignancy, and benign lesions were compared. RESULTS: We detected two tubal infiltrative carcinomas among 40 uterine endometrioid adenocarcinomas, 15 serous tubal intraepithelial carcinomas in 39 non-uterine pelvic serous high-grade carcinoma cases, seven papillary tubal hyperplasias in 13 serous borderline tumor cases, and 11 endometriotic foci and four adenomatoid tumors among all cases sampled with the SEE-FIM protocol. Using the Classical Method, we detected only one serous tubal intraepithelial carcinoma in 113 non-uterine pelvic serous high-grade carcinoma cases and two papillary tubal hyperplasia cases in 31 serous borderline tumors. We did not identify additional findings in 185 uterine endometrioid carcinoma cases, and neither endometriotic focus nor adenomatoid tumor was shown in other lesions by the Classical Method. CONCLUSIONS: Benign, premalignant, and malignant lesions can possibly be missed using the Classical Method. The SEE-FIM protocol should be considered especially in cases of endometrial carcinoma, nonuterine pelvic serous cancers, or serous borderline ovarian tumors. For other lesions, at least a detailed examination of the fimbrial end should be undertaken.
