Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...

PURPOSE We determined clinical factors affecting the under grading of biopsy Gleason sum compared with prostatectomy pathology and developed a model predicting the probability of under grading. MATERIALS AND METHODS We analyzed a cohort of 1,701 patients treated for prostate cancer at our institution between 1988 and 2007 with complete biopsy and pathological data available. Patients with a b...
Background-Histologic grading has been used as a prognostic factor and for clinical behavior evaluation of oral squamous cell carcinoma (SCC) for the past several decades. At the same time, the prognostic value of different grading classifications remains controversial. Methods-A retrospective study of 48 cases of tongue SCC was undertaken to compare different grading systems and their relation...
