Gravitational microlensing is an astronomical phenomenon where the gravity of a foreground massive object bends the rays of light of a background source into images. Effectively, the background source appears to be magnified with respect to time. Since this does not require detection of light from the lens, gravitational microlensing can be used to study different populations of objects in the galaxy, even the extra-solar planets. This phenomenon was practically formulated and investigated since the last decade of 20th century by a few observing groups. Today gravitational microlensing is observed and monitored by fourth generation telescopes towards high density stellar fields like the Galactic Bulge, Large and Small Magellanic clouds. With the increased capabilities there are numerous microlensing events that are detected but not yet analysed. Analysing these events, especially formed by a binary lens is not only challenging but tedious task. However with a suitable model that exp...

Background: There is no clear cut way of predicting which patients would develop PSA failure after radical prostatectomy for localised prostate cancer. Aims: To investigate the hypothesis that pursuant to radical prostatectomy for localised prostate cancer, surgical margin involvement and non-involvement influence the PSA failure and non failure rate. Patients Materials and Methods: The Clinical records, laboratory results including histology reports, serum PSA levels, all radiological investigations and reports of our initial 50 consecutive patients who underwent radical prostatectomy were reviewed and outcome of the prostatectomy was recorded with regard to PSA failure or non failure as well as surgical margin involvement or non involvement by tumour. Analysis of outcome was done to ascertain the proportion of patients who developed PSA failure and non failure in both patients whose tumours involved the surgical margin and those without margin involvement. Statistical analyses wer...
