BACKGROUND The aim of the present study is to investigate the clinical relevance of aortic calcification in urolithiasis patients. METHODS Between January 2010 and September 2014, 1221 patients with urolithiasis were treated in Oyokyo Kidney Research Institute and Hirosaki University Hospital. Among these, 287 patients (Stone group) on whom adequate data were available were included in this r...
Introduction: Cholelithiasis is a common disease. Since about 10 to 15 percent of choletithiasis patients have CBD (Common Bile Duct) stone as well as, the detection of CBD stone seems crucial in these patients. Regarding to cholodocholithiasis, the stone is extracted by ERCP (Endoscopic Retrograde Cholangio Pancreatography) and then, cholecystectomy is performed. The remaining CBD stone may ca...
Abstract Picking arrival times of P and S phases is a fundamental time-consuming task for the routine processing seismic data acquired by permanent temporary networks. A large number automatic pickers have been developed, but to perform well they often require tuning multiple parameters adapt them each dataset. Despite great advance in techniques, some problems remain, such as difficulty accura...
INTRODUCTION Urinary stone disease is a major urological condition. Endourologic techniques have influenced the clinical approach and outcomes. Open surgery holds a historic importance in the management of most conditions. However, complex kidney stone burden may be amenable to successful results with open stone surgery. In this article, we report our eighteen cases of complex urinary stone dis...
The collection of the rough set pairs of an approximation (U, R) can be made into a Stone algebra by defining two binary operators and one unary operator on the pairs. By introducing a more unary operator, one can get a regular double Stone algebra to describe the rough set pairs of an approximation space. Sequent calculi corresponding to the rough alg...
Statement of Problem: Different temperature and moisture around Iran and wide usage of stone type IV in dental laboratories in our country were the reasons for us for doing this study. Purpose: In this survey the effect of temperature, moisture and time on dimensional change of dental stone type IV (Velmix) were investigated. Materials and Methods: In this experimental study cube shape Metal mo...
PURPOSE To evaluate factors affecting the success rate of stone fragmentation and stone-free rate after extracorporeal shockwave lithotripsy (SWL) in treatment of upper urinary tract stones. MATERIALS AND METHODS A total of 121 patients with upper urinary tract calculi underwent SWL treatment. RESULTS Success rate of stone fragmentation after SWL was 73.6% (89/121). In 89 patients who had s...
Order batching is one of the methods used in warehouses to minimize the travel distance of pickers. In this paper, we focus on developing order-batching methods for an order-picking warehouse with two cross aisles and an I/O point at one of its corners. Each of these methods is made up of one seed-order selection rule and one accompanying-order selection rule. Eleven seed-order selection rules ...
