OBJECTIVE We assessed the incidence of high-grade prostatic intraepithelial neoplasia (HGPIN) in prostates removed for bladder cancer, and evaluated its correlation with preoperative serum prostate specific antigen (PSA). MATERIALS AND METHODS We reviewed the histology of the prostate from men who underwent cystoprostatectomy for bladder cancer without known prostate pathology prior to surger...
In the present study, to resolve the problems in fusion welding methods as well as to increase the strength, FSW method was used to join aluminum alloy sheets 6061 and 2024. Moreover, optimal parameters for joining of these two alloys were also taken into consideration. Various tool rotation speeds of 565, 950 and 1500 rpm were selected. For each tool rotation speed, two traverse speed variable...
Rock abrasivity is an essential factor for selecting cutting tools, estimating tool wear and life, and ultimately, matching various mechanized excavation systems with a given geologic condition. It also assists engineers to determine economic limits of different cutting tools and machines used in civil and mining projects. The Cerchar abrasion test is a simple and most widely used method for ro...
To date, few tools for aligning protein-protein interaction networks have been suggested. These tools typically find conserved interaction patterns using various local or global alignment algorithms. However, the improvement of the speed, scalability, simplification, and accuracy of network alignment tools is still the target of new researches. In this paper, we introduce Pin-Align, a new tool ...
This work presents the results for a coupled neutronic-thermalhydraulic-thermomechanic pin-level depletion calculation of PWR fuel assembly using Serpent2-SUBCHANFLOW-TRANSURANUS. tool is based on semi-implicit scheme with pin-by-pin feedback, mesh-based field exchange and an object-oriented software design. The impact including fuel-performance capabilities analyzed, focus high-burnup effects....
A mathematical model to describe the detailed three-dimensional transient heat transfer process in friction stir welding (FSW) is presented. This work is both theoretical and experimental. An explicit central diVerential scheme is used in solving the control equations, the heat transfer phenomena during the tool penetrating, the welding and the tool-removing periods that are studied dynamically...
INTRODUCTION Although laparoscopic adrenalectomy (LA) is considered as a gold standard approach for adrenalectomy, there are minimal data describing options and outcomes of LA after previous ipsilateral nephrectomy (PIN). AIM To describe our results in a group of patients who underwent LA after PIN. MATERIAL AND METHODS From August 2004 to October 2012 we performed at our institution 88 LA....
abstract listening is a key and main tool in second language skill and its development is of prime concern to teachers and learners. furthermore, the application of technology in language classrooms has become more commonplace in the last fifty years. computer and the internet have made foreign language materials easy to access and use. so, the present study is an attempt to examine the effec...
Background and Aims: The seal provided by a root canal filling may be compromised by post space preparation. The aim of this study was to compare coronal microleakage around cast posts and prefabricated pins. Materials and Methods: Thirty-eight extracted single-rooted, maxillary human teeth were prepared with step back method and filled with gutta-percha and sealer. After removing 8 mm of coro...
