Fewer articles were identified to report the evidence or information for decompression sicknesses, exceptional blood loss, intracranial abscess, compromised skin grafts and flaps, and thermal burns.
The grasshopper endeavours to get rid of the parasites by constantly flapping the elytra and wings, which get worn and reduced to about a third of their length.
The stories were accompanied by drawings in a book in which flaps could be opened so that the children could see whether the character found the desired object.
Another finding indicates that evidence for compromised skin flaps and grafts was contradicted by two of the articles.
The rotation rate of the flaps decreases linearly to zero during the course of the motion.
Their form is shown to change as the plume develops fine-scale structure and flapping becomes less important.
The flaps are fastened to the ground in same manner, except a piece left loose at one end to serve as a door.
One child is made the hunter; the others run off, flapping their arms and croaking like ravens or leaping and howling like wolves.
