MODELLING AND SIMULATION OF ROCKING SUITCASES

The rocking motion of two-wheeled suitcases is investigated.A rigid body mechanical model of the suitcase is constructed.All of the possible motion states (both wheels on the ground, one Knife Sharpening Steels wheel on the ground, none of the wheels on the ground) are taken into account.The switching between the motion states is accomplished by a

Expression of hes, iha, and tpsA codified in locus of adhesion and autoaggregation and their involvement in the capability of shiga toxin-producing Escherichia coli strains to adhere to epithelial cells

Abstract Objectives Shiga toxin-producing Escherichia coli strains LAA-positive are important cause of human infection.The capability to adhere to epithelial cells is a key virulence trait, and genes codified in LAA pathogenicity island could be involved in the adhesion during the pathogenesis of LAA-positive STEC strains.Thus, our objectives were
