Let X be a completely regular space and let A(X) be a ring of continuous real-valued functions onX which is closed under local bounded inversion. We show that the structure space of A(X) is homeomorphic to a quotient of the Stone–Čech compactification of X. We use this result to show that any realcompactification of X is homeomorphic to a subspace of the structure space of some ring of continuo...
Hypertrehalosaem ic horm ones I and II from the corpus card iacum o f the A m erican cockroach (Periplaneta americana) were separated by reversed-phase h igh-perform ance liquid chrom ato graphy using a N ucleosil C 18 colum n with a trifluoroacetic acid /aceton itrile gradient. T he eluent was monitored at 206 nm and the hypertrehalosaem ic activity detected by bioassay. T he am ino acid comp...
Abstract Background and objectives: Infection stones are the directly due to persistent or recurrent infection with Urease producing bacteria. they may be exacerbated by urinary obstruction or stasis. Also, some drug components like ciprofloxacin can be the cause of stone formation. We aimed at studing antibiotic resistance of bacteria isolated form kidney stones and Urinary tract infection(UtI...
This paper gives an overview of the OBST persistent object management system. OBST has been developed by the Forschungszentrum Informatik (FZI) as a contribution to the STONE project.1 The paper summarizes the design objectives and the current status of OBST, and highlights forthcoming developments with the system.
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...
The aim of this paper is to test the information content of the term premium in predicting the inter-war recessions in the USA and UK. A probit model is used to explain a binary variable identifying recessions with the term premium as the explanatory variable. We find that the term spread is a good predictor of the US business cycle in the inter-war period and is moderately successful in predic...
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...
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...
