the carob moth, ectomyelois ceratoniae (zeller), belongs to the family pyralidae and the subfamily phycitinae. in spite of some features of sexual dimorphism in size and shape in the order lepidoptera and the mentioned family, it has not been recorded in this species. in the current study, sexual dimorphism in the wing shape and size of carob moth on four hosts (pomegranate, fig, pistachio and ...

The aim of this paper is to provide an aeroelastic computational tool which determines the induced wing loads during flapping flight. For this purpose, a Finite Element (FE) code based on a four-node plate bending element formulation is developed to simulate the aeroelastic behavior of flapping wings in low incompressible flow. A quasi-steady aerodynamic model is incorporated into the aeroelast...

Case Description- A 20-day-old pigeon chick with left wing distal to the carpal joint into left flank presented to our avian medicine and surgery clinic. Clinical Findings-The bird had a mal-shaped wing structure, whereas the axial skeleton, thoracic and pelvic limbs skeleton were normal radiographically and clinically, excluding the left wing. The only clinical sign observed was recumbency. Tr...

In this study the centre manifold is applied for reduction and limit cycle calculation of a highly nonlinear structural aeroelastic wing. The limit cycle is arisen from structural nonlinearity due to the large deflection of the wing. Results obtained by different orders of centre manifolds are compared with those obtained by time marching method (fourth-order Runge-Kutta method). These comparis...

Extensive wind tunnel tests are conducted to evaluate surface pressure distribution of a semi span swept wing. The wing section has a laminar flow airfoil similar to NACA 6-series airfoils. The investigations are conducted at various speeds and angles of attack. Surface pressure distribution over the wing upper surface is measured for both chordwise and spanwise sections. Statistical analyses a...

This study experimentally investigates the effects of sweep angle and finite wing on transonic buffet, studying two-dimensional (2-D) three-dimensional configurations. Background-oriented schlieren stereographic particle image velocimetry (PIV) have been used as measurement techniques, performing experiments an OAT15A airfoil (clamped to both side windows wind tunnel), unswept wing, two swept w...

acute respiratory distress syndrome (ards) is a complex disorder of heterogeneous etiologies characterized by a consistent, recognizable pattern of lung injury and a potentially devastating form of acute inflammatory lung injury with a high short-term mortality rate and significant long-term consequences among survivors. recently, the new definition of ards has been published, and this definiti...

Planar cell polarity (PCP) is a level of tissue organization in which cells adopt a uniform orientation within the plane of an epithelium. The process of tissue polarization is likely to be initiated by an extracellular gradient. Thus, determining how cells decode and convert this graded information into subcellular asymmetries is key to determining how cells direct the reorganization of the cy...
