Gravitational uncertainties from dimension-six operators on supersymmetric GUT predictions
We consider the gravity induced dimension six terms in addition to the
dimension five terms in the SUSY GUT Lagrangian and find that the prediction
for may be washed out completely in supersymmetric grand unified
theories unless the triplet higgs mass is smaller than GeV.Comment: 7 pages,latex.Title of original version changed,text added and a

Implications of supersymmetric SU(15) grand unification
We consider the supersymmetric version of the grand unification scheme based on SU(15). We apply the constraints on the coupling constants form the LEP data and require the coupling constants to be less than one. We find that the nice feature of low energy unification is lost in the supersymmetric framework, implying that any signal of supersymmety will rule out the possibility of low energy unification

Hydrogen-antihydrogen oscillations: signature of intermediate mass scales in GUTs
Hydrogen-antihydrogen oscillations and the double nucleon decay (pp, np and nn) into two antileptons are discussed in the context of SO(10), E(6) and SU(16) GUTs. It is shown that the intermediate mass scales of the GUTs concerned govern the amplitude of these processes which are found to compete with the other baryon nonconserving processes in SU(16) GUT
