Measurements are reported on the in-plane and the perpendicular components of the remanence a tape acquires on passing through the steady field of a recording head. The tape coatings were oriented and unoriented particles of y-Fe,O,, oriented CrO, and unoriented Co-substituted y-Fe,O,. The two writing heads used had 10pmand 2.25pm-gaps, respectively. In each case the in-plane magnetization incr...

We give ruler and compass constructions of three Archimedean circles in an arbelos, each with the endpoints of a diameter on the smaller semicircles. In the first case, the diameter contains the intersection of the defining smaller semicircles of the arbelos. In the second case, these endpoints are the intersections of the smaller semicircles with the lines joining the endpoints of the base of ...

Introduction: In human heart, right atrio-ventricular orifice is guarded by tricuspid valve, which lies at the junction of right atrium and right ventricle of the heart controlling and directing unidirectional blood flow during ventricular diastole. Irreparable damage to tricuspid valve calls for its replacement using prosthetic valves. Prosthesis of these synthetic valves need detail knowledge...

Presence of lymph node (LN) metastasis is a strong prognostic factor in breast cancer, whereas the importance of extra-nodal extension and other nodal tumor features have not yet been fully recognized. Here, we examined microscopic features of lymph node metastases and their prognostic value in a population-based cohort of node positive breast cancer (n = 218), as part of the prospective Norweg...

Regular arrays of TixSn11xO2 nanostructures were produced through glancing angle sputter deposition onto self-assembled close-packed arrays of 200-nm-diameter and 1-μm-diameter polystyrene microspheres respectively. The anisotropic nanoflakes grown on 200-nm-diameter polystyrene microspheres exhibited macroscopic-wetting anisotropy, with the apparent contact angle observed parallel to the direc...

Recent studies have shown the possibility of water transport across carbon nanotubes, even in the case of nanotubes with small diameter (0.822 nm). In this case, water shows subcontinuum transport following an ordered 1D structure stabilized by hydrogen bonds. In this work, we report MD simulations describing the effect of a perpendicular electric field in this single-file water transport in ca...

The deformation of armchair single-walled carbon nanotube under transverse electric field has been investigated using density functional theory. The results show that the circular cross-sections of the nanotubes are deformed to elliptic ones, in which the tube diameter along the field direction is increased, whereas the diameter perpendicular to the field direction is reduced. The electronic st...
