  In this work we investigate the presence of lump-like solutions in models
described by a single real scalar field. We take advantage of a procedure
recently used to describe explicit analytical solutions and we study several
distinct models, showing how the parameters can be used to control the specific
features of the lump-like structures. The proposed models are of direct
interest to the construction of q-balls, to induce tachyonic excitations and
gravitating structures of nontopological profile on braneworld models with a
single extra dimension, to map solitons in optical fibers, and to describe
collective excitations in Bose-Einstein condensates.
