on the kinetic depth effect.the problem of the kinetic depth effect is revisited. we study how many points in how many views are necessary and sufficient to recover structure. the constraints in the cases where the velocities of the image points are known, and the positions of the image points are known with the correspondence between them established, are different and they have to be studied separately. in the case of two projections of any number of points there are infinitely many solutions, but if we regularize the pr ...20082719982
alumina as stationary phase for ion chromatography and column-coupling techniques.columns packed with alumina were combined with common anion-exchange columns and applied to the ion chromatographic determination of sulphate in brines and biological fluids and for the trace determination of iodide in mineral waters and fruit juice samples. alumina was found to be a highly selective stationary phase for the preconcentration of sulphate from complex matrices. further, owing to its selectivity, which is different from that of r4n+-type anion-exchange materials, it is well suited ...20082600151
complications of cardiac catheterization and angiography in patients with valvular heart disease. va cooperative study on valvular heart disease.complications were surveyed prospectively in 2,029 catheterizations performed on 1,483 patients from the 13 centers participating in the va cooperative study on valvular heart disease. complications were reported in 6.9% of 1,559 preoperative procedures of which 2.6% were major and 0.2% fatal. clinical predictors of complications were hypertension and the precatheterization diagnosis of aortic stenosis. nevertheless, patients with aortic stenosis successfully tolerated left ventriculography, whi ...20092720763

nonionic contrast agents and coagulation.the chemotoxicity of nonionic and ionic contrast media is discussed with reference to chemical structure. second-generation nonionic contrast media have the lowest chemotoxicity of any agents because of the uniform distribution of hydrophilic groups around the molecule, which mask the hydrophobic iodine atoms. previous investigations show that second-generation nonionic agents have the same qualitative hematologic effects as other contrast agents. the less marked quantitative hematologic effects ...20103058638

three years' experience with an ileal low pressure bladder substitute.at the beginning of this century it was realised that peristalsis would cause incontinence if bowel was used for augmentation or substitution of the bladder. trans-section of the antimesenteric border and cross-folding of the intestinal segments (goodwin's cup-patch technique) is an efficient means of solving this problem and has been successfully used in the kock pouch. we anastomosed the ileal low pressure reservoir to the membranous urethra in 22 male patients following radical cystoprostatec ...20102920259
