Texas has exhibited a “one party political culture” since joining the union. No matter the party affiliation Texas has always been conservative. What impact do you think this conservative culture would have had on the Republican party when almost 100% of the Conservative Southern Democrats, switched to the Republican party in the late 90’s?
besides being capable of punch so rapid, the reality that mantis shrimps’ raptorial appendages are capable of resist such massive forces stimulated researchers to analyse the structure of their clubs. In some groundbreaking research, researchers have found that a one-of-a-kind herringbone shape, that has yet to be determined in different animals, exists within the fibres of the mantis shrimp’s claws. This unique and strong herringbone shape protects the club from harm in the course of impact and also enables it to exert massive amounts of force on its prey . to understand how this helps beef up the membership, it's miles beneficial to recognize how various fibre orientations help reinforce materials. for instance, plywood, as visible in discern 7, is strengthened by way of stacking many layers of timber in with the fibres of successive layers orientated perpendicularly to every different . figure 7 : structure of plywood. Successive layers have fibres arranged perpendicular to every other to increase structural integrity. further, the alpha-chitin fibres inside the mantis shrimp’s claws are orientated in varying instructions. in place of simply being perpendicular to each other, each layer is oriented with a moderate angular offset to the opposite, main to a helicoidal structure. On top of that, the fibres in the equal aircraft are sinusoidally arranged, main to the herringbone shape shown below in figure 8 . This unique structure facilitates enhance resilience by using increasing the path length for crack growth, taking into account greater power to be dissipated . parent 8 : The helicoidal (left) and herringbone (proper) shape of alpha-chitin fibres in the mantis shrimp’s claws. The mantis shrimp’s clubs had been additionally placed in a synchrotron, and bombarded with x-rays to study the cloth composition of its membership. It become discovered that the claw was not most effective made from a single cloth, but rather consisted of various composites with distinct young’s moduli- a measure of the resistance of the material to elastic deformation, or how stiff a cloth is . go-sectional evaluation of the club revealed that there were three wonderful domain names- the impact area, the periodic vicinity and the striated region, as seen in determine nine, every area with consecutively reducing young’s moduli . Researchers speculate that the propagation of cracks is hampered via the changing young’s moduli, which beautify the damage tolerance and effect resistance. The degree to which such cracks propagate will rely upon the route of the crack relative to the orientation of the chitin fibre .>GET ANSWER
