This cross sectional study was conducted to detect carcinoma of prostate in clinically benign enlarged gland and to evaluate the efficacy of Digital rectal Examination in detection of prostatic cancer in patients presented at Khyber Teaching Hospital, Peshawar from July 1998 to July 1999. Patients presenting with lower urinary tract symptoms over the age of 50 years were evaluated on English version of International Prostate Symptoms Score (IPSS), clinically examined and post-voiding residual urine determined on abdominal sonography. The selection criteria were; Severe IPSS, absence of signs of malignancy on Digital Rectal Examination (DRE) and post-voiding residual urine more than 100 ml. Thus a total 100 patients were selected for further study. Four ml blood was taken to assess Prostate Specific Antigen (PSA) level pre-operatively. All these patients underwent either transvesical prostatectomy or transureth...

SiO x coatings were ...

It is shown that the mass of black hole reduces with the accretion of phantom energy. We compute accretion rate onto Bardeen black hole at critical point. Furthermore, we obtain the conditions at critical point, under which accretion is possible and also discuss certain relevant cases. Finally, we discuss the validity of generalized second law of thermodynamics at the event horizon of Bardeen black hole.

It is shown that the GSL is always respected for alpha0 <= 0, whereas for alpha0 > 0 the GSL is respected only if pir˜2A+/ℏ < alpha.
