Abstract Siphon-shaft spillways can discharge large amounts of water down to the crest level in a narrow reservoir thanks siphonic pressures. However, cavitational pressures siphon-shaft limit operating head these spillways. An enlargement at shaft mouth reduce vacuum and velocities within flows, thereby removing risk cavitation occurring. In this study, four different enlarging profiles with v...

A computer simulation system, which is based-siphon Petri net for control of concurrent processes of the reusable resources, that is mainly aimed to provide guidelines for control and management engineering of flexible manufacturing systems (FMSs) is presented in this work. We present an important technique for the analysis of siphon Petri net (PN) based on structural analysis, control, and sim...

The defensive siphon and gill withdrawal reflex of Aplysia is a simple reflex mediated by a well-defined neural circuit. This reflex exhibits classical conditioning when a weak tactile stimulus to the siphon is used as a conditioned stimulus and a strong shock to the tail is used as an unconditioned stimulus. The siphon withdrawal component of this reflex can be differentially conditioned when ...

The functional role of inhibition in the neural network underlying the siphon withdrawal response (SWR) of Aplysia was assessed by examining a recurrent circuit comprised of identified inhibitory interneurons (L30s), and excitatory interneurons (L29s). We previously showed that activity-dependent potentiation of the L30 inhibitory synapse onto L29 can regulate the net excitatory input elicited ...

We retrospectively reviewed the clinical course and angiograms of 15 patients with carotid siphon stenosis of 50% or greater. Fourteen had less than 50% stenosis at the origin of the ipsilateral internal carotid artery, and one had a greater degree of stenosis but underwent endarterectomy after an initial angiogram. Angiograms were examined for evidence of hemodynamic abnormalities in addition ...

The gill- and siphon-withdrawal reflex of Aplysia undergoes classical conditioning of its amplitude and duration when siphon stimulation (the conditioned stimulus, CS) is paired with tail or mantle shock (the unconditioned stimulus, US). This conditioning of a preexisting response exhibits both temporal and stimulus specificities, which can be accounted for by activity-dependent enhancement of ...
