THREE DIMENSIONAL RECONSTRUCTION OF ENERGY STORES FOR JUMPING IN PLANTHOPPERS AND FROGHOPPERS FROM CONFOCAL LASER SCANNING MICROSCOPY

Three dimensional reconstruction of energy stores for jumping in planthoppers and froghoppers from confocal laser scanning microscopy

Jumping in planthopper and froghopper insects is propelled by a catapult-like mechanism requiring mechanical storage of energy and its quick release to accelerate the hind legs rapidly.To understand the functional biomechanics involved in these challenging movements, the internal eye pencil skeleton, tendons and muscles involved were reconstructed

The potential of additively manufactured porous absorbers in the design of multi-layer microperforated absorbers

Microperforated absorbers (MPA) are a well-established technology for attenuating sound in flow carrying ducts.MPAs usually consist of a Wall Sconce microperforated panel (MPP) in combination with a cavity as back volume.The damping maxima of MPAs occur in the range of their resonant frequencies and the effect is narrowband compared to porous or fi
