Fast magnetic resonance coronary angiography with a three-dimensional stack of spirals trajectory
(WILEY, 1999)
In this work, three-dimensional (3D) spiral imaging has been utilized for magnetic resonance coronary angiography, Spiral-based 3D techniques can dramatically reduce imaging time requirements compared with 3D Fourier ...
Breaks in the radial oxygen abundance and corotation radius of three spiral galaxies
(WILEY-BLACKWELL, 2011)
The correlation between the breaks in the metallicity distribution and the corotation radius of spiral galaxies has been already advocated in the past and is predicted by a chemodynamical model of our Galaxy that effectively ...

(Taylor & Francis, 2005-04)
A new ichnofossiliferous locality in Salta Province (northwest Argentina) contains an association with numerous irregular spiral traces assigned to Spirodesmos milanai n. isp., in mature sandstones and quartzites with ...
Signatures of galaxy-cluster interactions: Spiral galaxy rotation curve asymmetry, shape, and extent
(UNIV CHICAGO PRESS, 2001-04)
The environmental dependencies of the characteristics of spiral galaxy rotation curves are studied in this work. We use our large, homogeneously collected sample of 510 cluster spiral galaxy rotation curves to test the ...
