⎯In this paper, we construct a pair of Mond-Weir type second order symmetric dual problems, in which the objective function contains support function and is, therefore, nondifferentiable. For this pair of problems, we validate weak, strong and converse duality theorems under pseudobonvexity – pseudoboncavity assumption on the kernel function that appears in the problems. A second order self dua...

any portion of the membranous or the bony labyrinth. A primary or secondary deficiency of the cochlear nerve may also present as a congenital anomaly. CT and MRI allow for a detailed analysis of each lesion and they can provide guidance for the proper treatment of each patient. Both CT and MR imaging can be used to detect inner ear malformations, yet the two techniques are often complementary. ...

In this work, CFD is used to simulate the flow in an existing thermal labyrinth located at the basement of a hospital building. This labyrinth is an underground channel equipped with water tanks to increase the thermal mass and reduce the heating and cooling demand of the building. Thermal energy storage in the water tanks is a complex heat transfer phenomena involving turbulent forced convecti...

A physical model for flow characteristics analysis of labyrinth-channel emitter is reconstructed by Reverse Engineering from an injection molded part, and both laminar flow and turbulence models are adopted to simulate the flow state under the condition of low Reynolds numbers. According to the distribution of separation and reattachment points, the onset of transition from laminar to turbulent...

The adult human temporal bone was investigated using micro-CT scans. Various aspects of the osseous labyrinth were presented in figures which are effect of the volume rendering. The 3D reconstructions were performed to visualize the cochlea and the semicircular canals embedded in the petrous bone. The final product of this study was a digital three-dimensional model of the entire osseous labyri...

After injecting a solution of a fluorescent retrograde neuronal tracer (Fast blue, Diamidino compound 253/50) into the perilymphatic space of the frog labyrinth (Rana esculenta), labeled cells were found in the ventral and dorsal nuclei of the VIIIth nerve and in the nucleus reticularis medius. We consider these labeled cells to be the origin of the efferent innervation of the frog labyrinth. N...

Foetuses are a source of scientific information to understand the development and evolution of anatomical structures. The bony labyrinth, surrounding the organ of balance and hearing, is a phylogenetically and ecologically informative structure for which still little concerning growth and shape variability is known in many groups of vertebrates. Except in humans, it is poorly known in many othe...
