It is suggested that sublingual nitroglycerine can improve the ability of T1-201 for detection of viable myocardium. Methods and Results: In a randomized, double blind study, 50 patients who had fixed defects on stress-redistribution scan, were randomized into two groups. In group I, patients received 0.4-0.8 mg sublingual nitroglycerine, before T1-201 reinjection. In group II, reinjectio...

Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...

Reverse redistribution pattern is defined as decreased activity in the myocardium in the rest phase of the myocardial perfusion scan in comparison with the stress images. There are many studies concerning the etiology and clinical significant of this phenomenon in nuclear medicine literature. The dominant idea about etiology of reverse redistribution is early wash out of the radiotracer f...

This paper will share current results of Amkor’s WLCSP board level reliability testing for both larger package size and smaller pitch. The 6.8mm test vehicle used for the large WLCSP package testing has 196 I/O set on a 400um pitch uniform array. The 300um pitch package has 100 I/O and is 3.8mm on each side. Amongst other design variations, solder alloy and redistribution layer thickness are ex...

numerical analyses have shown that successful flow simulations and the accuracy of solution noticeably depend on the number of nodes used in computational meshing. a suitable meshing should have the capability of adapting with main flow parameters. because the number of total nodes that can be used in numerical simulation is limited, making such grid for complex flows is almost difficult, if it...

reverse redistribution pattern is defined as decreased activity in the myocardium in the rest phase of the myocardial perfusion scan in comparison with the stress images. there are many studies concerning the etiology and clinical significant of this phenomenon in nuclear medicine literature. the dominant idea about etiology of reverse redistribution is early wash out of the radiotracer from th...

The article describes a model of interaction dynamics between a dislocation and dipolar dislocation loops. The interaction is essential for dipolar dislocation structure formation in early stages of a hardening process. For the description of the dislocation curve a direct parametric approach is employed whereas the loops are treated as rigid objects. The model equations are solved approximatel...

In the quest for the "ideal" soft tissue filler, many diverse products have been developed. The expanding market of available fillers is a testament that no one product will ideally suit all patients or clinicians. In addition, the challenge of satisfying the criteria of an ideal filler has driven researchers to take a variety of development paths. This has resulted in multiple categories to ch...
