Is the 'click' Mechanism of Dipteran Flight an Artefact of Cc14 Anaesthesia?
نویسندگان
چکیده
1. A frame-by-frame analysis of the wing movements of a fly shows characteristics which are incompatible with the accepted model for dipteran flight. 2. Higher amplitude wing beats result in greater velocities on the upstroke. 3. Detailed examination of the wing base articulation has uncovered a wing stop and DVM stretch mechanism. 4. It is argued that there is elastic energy storage during the downstroke which is released on the upstroke. 5. A novel mechanical model for wing movements is proposed which incorporates all the new findings and argues against a 'click' mechanism.

Critical Comments on a ' Novel Mechanical Model of Dipteran Flight ' ( Miyan & Ewing , 1985 )
According to the classical investigation of Boettiger & Furshpan (1952), the wing beat of flies is accompanied by a bistable mechanism, the 'click mechanism'. This mechanism is controlled by the pleurosternal and tergopleural muscles (see Heide, 1971; Pfau, 1978; Pfau, Schroeter & Steitz, 1977). Recently doubts have been raised concerning the existence of the click mechanism during flight (Miya...
متن کاملDipteran wing motor-inspired flapping flight versatility and effectiveness enhancement.
Insects are a prime source of inspiration towards the development of small-scale, engineered, flapping wing flight systems. To help interpret the possible energy transformation strategies observed in Diptera as inspiration for mechanical flapping flight systems, we revisit the perspective of the dipteran wing motor as a bistable click mechanism and take a new, and more flexible, outlook to the ...
متن کاملP100: A Review of Postoperative Cognitive Dysfunction and Neuroinflammation Processes Induced by Anaesthesia
Although anaesthesia is generally effective, safe and also an indispensable preoperative clinical approach, there is a really growing concern about usage, form of usage and dosage of it. Postoperative cognitive dysfunction (POCD) is one of the common postoperative complications that often affects elderly patients and includes a range of domains, may involve oxidative stress and neuroinflammatio...
متن کاملEffects of Flight Dynamics on Performance of One Axis Gimbal System, Considering Disturbance Torques
The gimbal stabilization mechanism system is used to provide the stability to an object mounted on the gimbal by isolating it from the base angular motion and vibration. In this paper the model of one axis gimbal system with dynamics flying object is introduced. The gimbal torque relationships are obtained using Newton’s second law equation on the assumption that gimbal is rigid body. The syste...

This paper deals with the leader-follower formation control problem while communication constraint in data transmitting is considered. From a practical point of view, we study the case in which unmanned vehicles are subject to the limited sensing, and communication is of a particular interest. A three-dimensional formation flight of multi-unmanned aerial vehicles with leader-follower configurat...
