Background & Aim: Doppler ultrasonography is important in diagnosis of renal diseases by demonstrating vascular anatomy and hemodynamics. There is not any fix doppler indices in all of the references and it is suggested that each center should have its own standards. Also it is proved that biologic indices are not the same in different societies. The present study was performed on normal Ir...
limits can be used in conjunction with a normalizing transformation, as illustrated by the logarithmic transformation in the preceding example from Nelson (1982). Transformations to achieve approximate normality are especially important in light of the lack of robustness of the prediction limits noted earlier. 2. Some instructors may wish to contrast prediction limits with tolerance limits; the...
plauded for developing assay techniques for protein identification that are at least available for problematic cases and for offering their help with characteristic generosity. Needless to say, the clinical constraints are most daunting. Patients will often get sicker while waiting for a diagnosis. Therefore, on occasion, the need arises to make the best guess as to the cause of amyloid disease...
Skiing and snowboarding have become more acrobatic with terrain park jumps and other manmade features playing a prominent role in an increase in serious spinal cord injuries. Yet these jumps rarely, if ever, involve formal or detailed design or engineering. This paper presents a coherent theory and methodology for the design of ski jump landing surfaces. The motion of the skier center of mass i...
BACKGROUND To simplify development of normal limits for myocardial perfusion SPECT (MPS), we implemented a quantification scheme in which normal limits are derived without visual scoring of abnormal scans or optimization of regional thresholds. METHODS AND RESULTS Normal limits were derived from same-day TI-201 rest/Tc-99m-sestamibi stress scans of male (n = 40) and female (n = 40) low-likeli...
