abstract background: high resolution ct scan has made early diagnosis of intraventricular hemorrhage (ivh) easier. posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the ct scan. methods: 904 patients were admitted in the nsicu from march 2001 to march 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (gcs les...

Two noncanonical Hamiltonian models are presented for the dynamics of a rigid body with an constrained moving point mass. One of these models is used to analyze stability of steady principal axis rotation of a rigid body with a spring-mass oscillator. The analysis gives necessary and sufficient conditions for stability of steady major axis rotation, as well as sufficient conditions for instabil...

The mol-ecule of the title thia-diazole derivative, C(11)H(11)N(3)O(2)S(2), has a butterfly-like structure and the whole mol-ecule is disordered with a site-occupancy ratio of 0.629 (4):0.371 (4). The mol-ecule is disordered in such a way that the 3-methyl-4-nitro-phenyl units of the major and minor components are approximately related by 180° rotation around the C-N bond axis. The dihedral ang...

The V-K colours along the minor axes of spiral galaxies typically change from red to blue with increasing distance, giving the impression that the near side is systematically screened by dust. Such a preferred orientation for dust screens is unlikely. Here we show that common extinction from the embedded dust layer in an exponential disk has the same effect, making the near side systematically ...

Reddening of the major axis compared to the minor axis on a given isophote, and asymmetry of the run of surface brightness and colour along the minor axis, are possible signatures of dust concentrated in the disk of an inclined two components galaxy, the first being somewhat ambiguous. From CFHT observations, these phenomena are shown to occur in nearly all disky ellipticals of sufficient flatt...

Using Langevin dynamics simulations, we investigate the dynamics of a flexible polymer translocation into a confined area under a driving force through a nanopore. We choose an ellipsoidal shape for the confinement and consider the dependence of the asymmetry of the ellipsoid measured by the aspect ratio on the translocation time. Compared with an isotropic confinement (sphere), an anisotropic ...

Every .nite two-dimensional partially ordered set has an inclusion representation by similar noncircular ellipses centered at the origin. The representing ellipses have the same ratio r of minor axis length to major axis length, and any r ∈ (0; 1) can be used for the representation. c © 2002 Elsevier Science B.V. All rights reserved.
