abstract background: the loop colostomy is one of the most popular techniques used as a protective maneuver for a distal anastomosis and/or temporary fecal diversion. we are introducing the use of a full thickness skin bridge under the large bowel instead of a glass rod which alleviates problems such as protrusion of the large bowel, retraction of the bowel into the abdomen after removing the r...

We determine how the tachyon condensations occur in various D-D̄ systems on orbifolds C/ZN by extending the solution generating technique. We propose some rules to classify types of noncommutative solitons as fractional D-branes. This identification gives consistent results with BSFT. The extended solution generating technique enables us to calculate more general decay modes of D-D̄ systems. kent...

In this paper we generalize theO(p+1, p+1) solution generating technique (this is a method used to deform Dp-branes by turning on a NS-NS B-field) to M-theory, in order to be able to deform M5-brane supergravity solutions directly in eleven dimensions, by turning on a non zero three form A. We find that deforming the M5-brane, in some cases, corresponds to performing certain SL(2,R) transformat...
