The aim of the present study was to investigate whether the vibratory characteristics of obturator prostheses are affected by bulb design, i.e.: the hollow or buccal flange type, and different lateral and medial bulb heights. Buccal flange and hollow bulb obturator prostheses were fabricated with two different lateral bulb wall heights and two different medial bulb wall heights. Ultimately, eig...

The offspring of caring parents may evolve specialized traits uniquely adaptive during their dependence on parental care. For example, the mouths of passerine nestlings are often bordered by enlarged and colorful rictal flanges expressed only during the nestling period. Although these traits are commonly hypothesized to act as visual signals during begging, noncommunication functions for the sp...

We appreciate the comments by Nezic et al. [1] regarding our article [2]. Nezic et al. pointed out the pinholes of the everting mattress sutures on the flange as the potential sites of bleeding. However, a recent Gelatin-sealed woven Dacron graft was considered because the problem was rare. In addition, we injected fibrin glue around the proximal suture line after sewing the Valsalva sinus skir...

T-stubs are important components in the application of component method; hence it is crucial to clarify T-stub mechanism for analysis mechanical properties steel joints. In this study, behavior was assessed via 6 static tests and 18 finite element models. The influences flange thickness, bolt spacing, diameter, stiffener rib on initial stiffness, ultimate bearing capacity, force were analyzed. ...

Begging is a complex display involving a variety of different visual and auditory signals. Parents are thought to use these signals to adjust their investment in food provisioning. The mechanisms that ensure the honesty of begging displays as indicators of need have been recently investigated. It has been shown that levels of corticosterone (Cort), the hormone released during the stress respons...

The Flowdrill technology, also known as thermal drilling or thermoforming drilling is a chip less process of shaping rims of holes through burring and it is an alternative to conventional technology of hole rims burring, realized using presses or welded nuts to obtain threaded joints [1, 2, 3]. It is applied everywhere, where it is necessary to obtain threaded joints of high strength without ap...

The development of leakage and strength a metallic bolted flange joint are investigated in this work. Finite element analyses 2D 3D have been developed using ANSYS to study steel bolt with an aluminium gasket. pressure-penetration criterion (PPNC) has used model fluid propagation between the Validation was performed benchmark test, published joint; agreement results is excellent. Results showed...
