The quotients Gk/Gk+1 of the lower central series of a finitely presented group G are an important invariant of this group. In this work we investigate the ranks of these quotients in the case of a certain class of conjugation-free groups, which are groups generated by x1, . . . , xn and having only cyclic relations: xitxit−1 · . . . · xi1 = xit−1 · . . . · xi1xit = · · · = xi1xit · . . . · xi2...

Introduction: Traditionally in reconstruction of lower limb soft tissue defects, muscle flaps have been the ‘Gold Standard’ for Gustillo Anderson Grade III B fracture involving upper and middle third defects. Lower third defects were usually reconstructed with free flaps. Evolution in flap surgery has enabled fasciocutaneous, adipofascial and superthin flaps to be harvested for the purpose of r...
