PURPOSE To compare intraoperative angle stability and postoperative outflow of two ab interno trabeculectomy devices that excise the trabecular meshwork with or without active aspiration and irrigation. We hypothesized that anterior segment optical coherence tomography (AS-OCT) allows for a quantitative comparison of intraoperative angle stability in a microincisional glaucoma surgery (MIGS) pi...

The performance of turbomachinery blade profiles, at low Reynolds numbers, is influenced by laminar separation bubbles (LSBs). Such a bubble caused strong adverse pressure gradient (APG), and it makes the boundary layer to separate from curved profile surface, before becomes turbulent. paper consists on joint experimental numerical investigation flat plate with gradient. experiment provides det...

In this paper, based on the theory of elastic structure analysis, considering rotational softening and centrifugal stiffening blade, dynamic model fir-tree rotating blade macroslip hysteresis dry friction contact surface tenon are established. Based mechanics, pressure distribution is innovatively established relationship between fit clearance has been derived. After discretized by finite eleme...

physical and mechanical properties of alfalfa (medicago sativa, l.) grind are required for optimum design of equipment used in transporting, processing and storage of the material. this study was conducted to determine the effect of particle size (2.38, 3.36 and 4.76 mm) and moisture content (8, 9.3 and 11% wb) on some physical and mechanical properties of alfalfa grind. these properties includ...

Control power on rotor wind turbine can be carried out by changing blade angle of attack through via pitch control and stall regulated method to produce much as well protect from high operate in rated power. By using search-based design optimize Blade Element Momentum Theory (BEMT) analyze aerodynamic performance for Recent work demonstrates that some very significant effect achieved constant s...

We studied the effects of wing deformation on the aerodynamic forces of wings of hovering hoverflies by solving the Navier-Stokes equations on a dynamically deforming grid, employing the recently measured wing deformation data of hoverflies in free-flight. Three hoverflies were considered. By taking out the camber deformation and the spanwise twist deformation one by one and by comparing the re...
