Reusable Surface Insulation (RSI) Material Samples

Test specimen data sheets are presented for 48 high temperature and 40 low temperature reusable surface insulation tiles. Tabular data show dimensions, density, coating weight, and final tile weight. Codes indicate basic material, surface coating, and hydrophobic treatment

Enhanced Model of Nonlinear Spiral High Voltage Divider

This paper deals with the enhanced accurate DC and RF model of nonlinear spiral polysilicon voltage divider. The high resistance polysilicon divider is a sensing part of the high voltage start-up MOSFET transistor that can operate up to 700 V. This paper presents the structure of a proposed model, implemented voltage, frequency and temperature dependency, and scalability. A special attention is paid to the ability of the created model to cover the mismatch and influence of a variation of process parameters on the device characteristics. Finally, the comparison of measured data vs. simulation is presented in order to confirm the model validity and a typical application is demonstrated

Oncologic Outcomes of Radical Prostatectomy and Prognostic Stratification in Patients with Clinically Locally Advanced Prostate Cancer

Oncologic outcomes of radical prostatectomy in 106 patients with clinically locally advanced prostate cancer were demonstrated. The mean follow-up was 50.6 (12-129) months. 5-year recurrence-free survival was 47.7 %, 5-year cancer-specific and overall survival - 85.8 %. Patients were devided into three different risk groups: low risk patients had PSA level <20 ng/ml, biopsy Gleason score ≤6 and absence of the seminal vesicle invasion of cancer; intermediate risk was noted when the patient had only one of poor prognostic factors (PSA ≥20 ng/ml or biopsy Gleason score≥7 or presence of cancer invasion to the seminal vesicle) and high risk patients had 2 or 3 poor prognostic factors. For patients of low, intermediate and high risk the biochemical reccurence rates were 14.3 %, 37.1 % and 70.2 %, respectively (p=0.002). The patients of intermediate and high risk had clinically significant higher risk of biochemical reccurence than those of low risk with odds ratio 3.0 and 8.5, respectively. Such grouping may help in guiding the individualized treatment for these patients
