Aiming at the complex structure and high manufacturing process requirements of traditional knotter, this article proposes a new rope knotting method.Based on the knotting method, a knotter is designed to use a new mechanism which is made up of two new incomplete gear mechanisms to drive rope clamping mechanism and rope hooking and griping mechanism
A major prediction of coevolutionary theory is that plants may target particular herbivores with secondary compounds that are selectively defensive.The highly specialized monarch butterfly (Danaus plexippus) copes well with cardiac glycosides (inhibitors of animal Na+/K+-ATPases) from its milkweed host plants, but selective inhibition of its Na+/K+

The depth of penetration (DOP) method is a well-known ballistic test method for characterisation and ranking of ceramic armour materials.The ceramic tile is bonded to a backing material of semi-infinite thickness, and the penetration depth of the projectile gives a measure of the performance of the ceramic.There is, however, an inherent variability
