THE INFLUENCE OF WATER AND SOLVENT UPTAKE ON FUNCTIONAL PROPERTIES OF SHAPE-MEMORY POLYMERS

In this contribution, diffusion of water, acetone, and ethanol into a polymer matrix has been studied experimentally and numerically by finite element approaches.Moreover, the present study reports an assessment of different thermomechanical conditions of the shape-memory (SM) performance, for example, stress- or strain-holding times in stress- or

single-minded (sim) is a master regulatory gene that directs differentiationin the central nervous system during Drosophilaembryogenesis.Recent identification of the mesectoderm enhancer(MSE) of sim has led to the hypothesis that two Snail(Sna)-binding sites in the MSE may repress sim expression inthe presumptive mesoderm.We provide evidence here t
