Query: Total cross-section at LHC from minijets and soft gluon resummation in
  the infrared region   A model for total cross-sections incorporating QCD jet cross-sections and
soft gluon resummation is described and compared with present data on $pp$ and
${\bar p}p$ cross-sections. Predictions for LHC are presented for different
parameter sets. It is shown that they differ according to the small x-behaviour
of available parton density functions.
