The objective of this work is to investigate the effect of the (possible) acid adaptation during growth in a glucose rich environment on the heat resistance of Escherichia coli K12 MG1655. E. coli cells were grown in TSB and/or TSB dextrose free broth until they reached the stationary phase. Afterwards, the stationary phase cells were added in TSB and/or TSB dextrose free broth and inactivation took place at 54 o C and 58 o C. It was observed that growth in a glucose rich environment leads to an increased heat resistance, most likely due to a certain level of acid and further heat adaptation via cross protection.
In this paper a dynamic model of a stepped beam excited by an electrodynamical actuator with non-negligible dynamics at one end is derived. As model ansatz the superposition of rigid-body and modal dynamics is chosen....

We establish the sound absorption mode of micro-nano aperture membrane material according to the classic porous media acoustic theory and cylindrical shell model theory and considering the viscous resistance theory and the heat conduction theory as well. Comparing the theoretical result obtained by simulating the sound absorption property through Matlab and the experimental result, we prove the validity of the mode and it conforms to the sound absorption law of the porous material. We predict the Acoustic Propagation roperties of ordered mesoporous thin film using this mode and find the absorption coefficient is very small and the absorption property of the micro-nano aperture membrane is poor.
