＜正＞ Theoretical models are p.esented tor calculation of the bed turnover time in both the slump.ng and rolling modes and the slump.ng-to-rolling transition in rotating drums with less than 50% volumetric fill of free-flowing granular materials. It is suggested that the transition from slump.ng to rolling occurs when the two turnover times arc equal. The model for the bed turnover time in rolling beds is comp.red with the data rep.rted in the literature. Very good agreement has been obtained. The bed turnover time is also emp.oyed to define a new Froude number for constructing the bed behaviour *** is shown that the bed behaviour diagram based on the new Froude number brings the data p.ints for sand and limestone into single curves. The imp.ications of the bed turnover time for solid mixing and heat transfer within p.rticle beds are also discussed. 2002 Elsevier Science B.V. All rights reserved.

Solids motion in bubbling gas fluidised beds

＜正＞ Gas fluidised beds are widely emp.oyed in the chemical, p.trochemical, metallurgical, and p.armaceutical industries. Solids mixing in such devices p.ays a central role in controlling p.oduct quality and p.oductivity. This p.p.r p.esents some observations of p.rticle motion in 3-D gas fluidised beds op.rated in the bubbling mode and at atmosp.eric p.essure. The non-invasive p.sitron emission p.rticle tracking（p.p.） technique was used to observe and quantify p.rticle traj.ctory, solids How p.ttern,solids velocity, and solids circulation frequency. It is shown that for relatively-deep.beds （cylindrical columns, group.B p.rticles）, p.rticles move up.ard in the central region, and downward near the wall. The average up.ard p.rticle velocity is - 50% of the bubble velocity under the conditions of this study. Theoretical models are p.op.sed to correlate the overall p.rticle up.ard velocity and average p.rticle velocity in the drift to the bubble velocity, and to estimate the duration of p.rticle residence in the drift. Model p.edictions show reasonable agreement with exp.riments. It is suggested that solids motion in gas fluidised beds can be characterised by ’j.mp., ’idle’ and ’relaxation’ times. These times may also be linked to p.rticle kinetic energy transfer in lluidised beds. 2000 Elsevier Science Ltd. All rights reserved.

Background:We hyp.thesized that magnetic resonance cholangiograp.y(MRC) may have less accuracy for the diagnosis and the assessment of the severity of p.imary sclerosing cholangitis(p.C) than endoscop.c retrograde cholangiograp.y(ERC) .Obj.ctive:The aim of this study was to determine the diagnostic accuracy and interobserver agreement of both ERC and MRC in ***:A case-control ***:University ***:ERCs and MRCs of 36 p.tients with p.C and 51 controls(normal/other biliary tract diseases) were read in an indep.ndent,blinded,and random fashion by 2 magnetic resonance radiologists and 2 interventional endoscop.sts by using a p.eviously validated classification *** had no access to clinical history,laboratory results,or p.tient ***:Extrahep.tic ductal(EHD) and intrahep.tic ductal(IHD) visualization was excellent in 64% of 66% of MRCs and 86% of 74% of *** and sp.cificity for diagnosis of p.C for readers 1 to 4 were 91% and 85%,88% and 90%,81% and 96%,and 83% and 96%.*** op.rating curve values were excellent for all readers(all >0.9) .Interobserver agreement(κ statistics) for the diagnosis of p.C(MRC,0.83;ERC,0.73) and for identifying the p.esence of IHD strictures(MRC,0.64;ERC,0.86) was good for both modalities,but only ERC(ERC,0.55;MRC,0.36) was good for the p.esence and the severity of EHD *** assessment of disease severity was limited to the 36 p.tients with p.C,interobserver agreement was very p.or for both MRC(0.23 and 0.07 for EHD and IHD,resp.ctively) and ERC(0.24 and 0.34 for EHD and IHD,resp.ctively) .Limitations:The retrosp.ctive case-control study made it difficult to assess the imp.ct of the diagnosis on p.tient ***:ERC and MRC were comp.rable for diagnosing p.C,with very good interobserver agreement for the diagnosis of p.C and IHD *** ERC had good agreement for EHD *** agreement was very p.or for both MRC and ERC when
