Double strap joint tests to determine the bond characteristics between CFRP and steel plates
No full textAdvanced composite materials offer remarkable potential in the upgrade of civil engineering structures. The evolution of CFRP (carbon fibre reinforced polymer) technologies and their versatility for applications in civil constructions require comprehensive and reliable codes of practice. Guidelines are available on the rehabilitation and retrofit of concrete structures with advanced composite materials. However, there is a need to develop appropriate design guidelines for CFRP strengthened steel structures. It is important to understand the bond characteristics between CFRP and steel plates. This paper describes a series of double strap shear tests loaded in tension to investigate the bond between CFRP sheets and steel plates. Both normal modulus (240 GPa) and high modulus (640 GPa) CFRPs were used in the test program. Strain gauges were mounted to capture the strain distribution along the CFRP length. Different failure modes were observed for joints with normal modulus CFRP and those with high modulus CFRP. The strain distribution along the CFRP length is similar for the two cases. A shorter effective bond length was obtained for joints with high modulus CFRP whereas larger ultimate load carrying capacity can be achieved for joints with normal modulus CFRP when the bond length is long enough

Comparative analysis of MIR168 promoters in three plant species
Get PDFMicroRNAs (miRNAs) play important roles in the regulation of gene expression by post-transcriptionally targeting mRNAs for cleavage or translational repression. miR168 is a key miRNA because it regulates the expression of the slicer protein ARGONAUTE1 (AGO1), which catalyzes mRNA cleavage. Interestingly, plant miR168s are highly evolutionarily conserved; however, it is unclear whether MIR168 promoter elements and expression patterns are also conserved. Here, we isolated MIR168 promoters from monocot rice and dicot grape genomes. To determine the expression pattern, different promoters were fused to a beta-glucoronidase reporter gene and the resulting constructs were then transformed in Arabidopsis. The results revealed clear differences in the MIR168 promoter sequence of monocot and dicot plant species. Moreover, the pattern of MIR168 promoter expression differed between monocots and dicots. These results suggest that, unlike that of miR168, the MIR168 promoter is not conserved in monocots and dicot
