Some consequences for LHC experiments from the results of cosmic ray   investigations above the knee
  Experimental data obtained in cosmic ray investigations at energies above the knee are discussed. All features observed at these energies starting from the knee, changes of mass composition and concluding with various types of unusual events are analysed in the framework of the new hadron interaction model producing blobs of quark gluon matter. Consequences for LHC experiments are considered.
