Weirs, as overflow structures, are extensively used for the measurement of flow, its diversion and control in the open canals. Labyrinth weir due to more effective length than conventional weirs, allows passing more discharge in narrow canals. Determination the design criteria for the practical application of these weirs need more investigation. Weir angle and its position relative to the flow ...

Computed tomography (CT) is the modality of choice for detailed imaging of the bony labyrinth. Usually, information about the complex three-dimensional anatomic structures of the inner ear is presented as two-dimensional section images. Interactive direct volume rendering is a powerful method for visualization of the labyrinth. Unlike other visualization methods, direct volume rendering enables...

The modern human bony labyrinth is morphologically distinct from that of all other primates, showing derived features linked with vestibular function and the overall shape of the cranial base. However, little is known of how this unique morphology emerges prenatally. This study examines in detail the developing fetal human labyrinth, both to document this basic aspect of cranial biology, and mo...

(1) The activity of 136 Deiters' neurons projecting to lumbosacral segments of the spinal cord has been recorded in decerebrate, partially cerebellectomized cats, and their response characteristics to sinusoidal stimulation of labyrinth and neck receptors have been related to cell size inferred from the conduction velocity of the corresponding axons. (2) Vestibulospinal neurons with faster cond...

In this paper, we intend to approach two specific hypermedia aspects; the structure that organizes the hypertextual information, as well as the route of reading that the user creates when advancing the links of a net. Our hypothesis is that the labyrinth is present in hypermedia systems in two ways: the first, more evident, is in the own organization at the moment of the project development. Th...

Introduction The nature and extent of membrane damage encountered in Meniere disease remains unexplained. Pressure-induced membrane stress may underlie the characteristic hydropic distention. Analysis of stress in the several vestibular chambers may offer insight into the nature and progression of Meniere disease. Objective Membrane stress levels will be assessed by constructing a specific mode...

Abstract In a stepped spillway, the spillway face is provided with series of steps from near crest to toe. This type attractive for water resource management because it dissipates energy that within flow. When dissipated by steps, reduces reduction otherwise must occur at toe spillway. present study, nine physical models slopes 15, 25, 45° and number varying 5 50 have been constructed. The spil...

1. A dogfish from which all six ampullae have been removed maintains its equilibrium; the righting reactions occur promptly; compensatory movements of the eyes occur in response to rotations in all planes except the horizontal; the compensatory position of the eyes is retained if the animal is held in an abnormal position. Both the static and dynamic functions of equilibrium continue, therefore...
