Abstract: For regulating the driving dynamics of a road vehicle, setpoints for the yaw rate {dot over (&PSgr;)} and the float angle &bgr; of the vehicle are generated continuously by evaluating a simulation computer implemented vehicle model. The simulation computer generates control signals for activating at least one wheel brake of the vehicle based on a comparison of the reference values {dot over (&PSgr;)}SO as a setpoint, and the actual values {dot over (&PSgr;)}I of the yaw rate continuously recorded by a yaw rate sensor. The vehicle model is represented by a linear differential equation system of the form [P]·({overscore ({dot over (X)})})=[Q]·({overscore (X)})+({overscore (C)})·&dgr;(t).

Abstract: The invention relates to new expression vectors. More particularly, the invention relates to expression vectors carrying a new type of promoters for the expression of the foreign gene, which was constructed from promoter P.sub.2 of E. coli ribosomal RNA operon and some regulatory sequences of E. coli las operon. The invention further relates to a method for the construction of the above vectors. The method is characterized by deleting most part of the structurgenes of E. coli ribosomal RNA operon (rrn operon) built in a suitable vector, joining together the part of operon rrn comprising promoter P.sub.2 with the beginning part of the lac operon outside the regions -35 and -10, downstream of them so as to create a new NsiI cleavage site at the joining point of the sequences originating from rrn and lac operons, deleting the inner TGCA sequence-element of the newly created NsiI cleavage site and building the structurgene to be expressed between these newly created regulatory sequences.

Abstract: Plasmid vectors and a process for the preparation thereof are disclosed having the same replication region as pBR322, but which have a substantially higher copy number per cell. The plasmid vectors contain a G.fwdarw.T point mutation at base pair 3074 of the pBR322 sequence which holds back synthesis of the repressor of plasmid replication, and also contain either no tetracycline resistance gene or the tetracycline resistance gene in an inactivated or weakened state.
