## Abstract

We discuss branes whose world-volume dimension equals the target space-time dimension, i.e. "space-time-filling branes". In addition to the D9-branes, there are 9-branes in the NS-NS sectors of both the IIA and IIB strings. The world-volume actions of these branes are constructed, via duality, from the known actions of branes with codimension larger than zero. Each of these types of branes is used in the construction of a string theory with sixteen supercharges by modding out a Type II string by an appropriate discrete symmetry and adding 32 9-branes. These constructions are related by a web of dualities and each arises as a different limit of the Hořava-Witten construction.
