  The results of a search for squarks and gluinos using data from ppbar
collisions recorded at a center-of-mass energy of 1.96 TeV by the D0 detector
at the Fermilab Tevatron Collider are reported. The topologies analyzed consist
of acoplanar-jet and multijet events with large missing transverse energy. No
evidence for the production of squarks or gluinos was found in a data sample of
310 pb-1. Lower limits of 325 and 241 GeV were derived at the 95% C.L. on the
squark and gluino masses, respectively, within the framework of minimal
supergravity with tan(beta)=3, A0=0, and mu<0.
