A variational technique is used to derive analytical expressions for the sensitivity of several geometric indicators of flow separation to steady actuation. Considering the boundary layer flow above a wall-mounted bump, the six following representative quantities are considered: the locations of the separation point and reattachment point connected by the separatrix, the separation angles at th...

PURPOSE To compare the morphologic and functional recovery of the retina after detachment and reattachment in an animal with a cone-dominant retina, the ground squirrel. METHODS Ground squirrel (Spermophilus beecheyi) retinas were detached for 1 day and reattached for 7, 35, or 96 days (n = 2, each time point). Flicker ERGs were recorded 1 day after the detachment and at various times after r...

Due to the more stringent aviation regulations on fuel consumption and noise reduction, the interest for smaller and mechanically less complex devices for flow separation control has increased. Plasma actuators are currently among the most studied typology of devices for active flow control purposes due to their small size and lightweight. In this study, a single dielectric barrier discharge (S...

Anterior crown fractures are the most common type of injury in dental trauma. The ideal treatment is to reattach the fragments as quickly as possible following intraoral and radiographic examination, but sometimes delayed treatment appointments are necessary because of uninformed patients/parents or multidisciplinary cases included endodontically and periodontically. Delayed reattachment may le...

PURPOSE Photoreceptor outer segments are in a dynamic state of membrane addition and disposal. This study was undertaken to determine how a standardized period of retinal detachment and varying periods of reattachment affect the renewal process. METHODS To investigate the effects that retinal detachment and reattachment may have on this process, the neural retina from 12 adult rhesus monkeys ...

In the feline model, retinal detachment initiates a cascade of changes that include photoreceptor-cell “deconstruction,” apoptotic death of some photoreceptors, neurite outgrowth from secondand third-order neurons, remodeling of photoreceptor synaptic terminals, and Müller-cell gliosis. We have previously shown that reattachment within 24 h halts or reverses many of these presumed detrimental c...

Traumatized anterior teeth require quick functional and esthetic repair. Tooth fragment reattachment is a simple and conservative clinical procedure to restore fractured anterior teeth. Different techniques of reattachment include enamel beveling, "v-" shaped internal enamel and dentin grooves, external chamfer, over contouring, and by placing fiber post, all of which were invasive methods. Thi...

OBJECTIVES To determine the reattachment rate of human retinal pigment epithelium (RPE) to different layers of human Bruch's membrane (BM). METHODS Explants of BM were prepared from 10 human cadaver eyes by removing native RPE. The RPE basal lamina, inner collagenous layer, elastin layer, and outer collagenous layer were exposed by sequentially removing each apical layer by mechanical or enzy...
