Despite a high patency rate and low incidence of infections, several complications have been described with the Brescia subcutaneous arteriovenous fistula. We recently observed five patients with swelling of the hand and wrist secondary to increased distal vein Air Max 90 For Sale
flow. Ligation of the distal vein, with or without proximal reconstruction resulted in cure. Proximal vein patency must be assessed.
A hydrostatic pressure induced ferromagnetism was found in a TbMn2 intermetallic Nike Air Max 2010 Canada
compound in a low temperature region below 50 K, where the helical spin structure takes place at normal pressure. This change in the spin structure is attributable to the disappearance of the magnetic moment at manganese atoms by the application of the pressure.
This paper defines an invariant associated to Whitehead's certain exact sequence of a simply connected CW-complex which is much more elementary — and less powerful — than the boundary invariant of Baues. Nevertheless, in good cases, it classifies the homotopy types of CW-complexes.
Starting from a simple mechanism of the movement of granular solids in a rotating cylinder, as first indicated by Vàhl, formulae are derived for the hold-up of an inclined rotary kiln, with and without end constrictions. A good agreement is found between the theoretical values and the experimental results.
