ABSTRACI . . A three-dimensional steady flow sunulanon at Repeak=580 was made in a smooth reverse curvature model that conformed to the gentle "S" shape from a human left femoral artery angiogram. T!Je objective of this numerical investigation was to fmd th~ ch~ges m velocity profile, shear stress, and pressure drop ?Ccwnng In the double-curved arterial vessel. At the outer wall In the fIrst be...

This study uses conjuring to investigate the effects of suggestion, social influence, and paranormal belief upon the accuracy of eyewitness testimony for an ostensibly paranormal event. Participants watched a video of an alleged psychic seemingly bending a metal key by the power of psychokinesis. Half the participants heard the fake psychic suggest that the key continued to bend after it had be...

Octopus arm movements provide an extreme example of controlled movements of a flexible arm with virtually unlimited degrees of freedom. This study aims to identify general principles in the organization of these movements. Video records of the movements of Octopus vulgaris performing the task of reaching toward a target were studied. The octopus extends its arm toward the target by a wave-like ...

The dissemination of the optical fibers structures, especially in the access network had impose new challenges. In this work we present the study of macro bending losses in single mode optical fibres, namely the bend loss as a function of the Radius of Bend for SMF fiber are given. The experimental results are compared with the results from the improved formula for bend loss determinate by R. S...

risk assessment and management of petrochemical feed and product transportation pipelines is very important to preventing probable accidents. so, 60 pipelines evaluated by chemical exposure index and chlorine pipeline due to high hazard distances selected for relative risk analysis. the chlorine pipeline with 3468 meter length divided to 100 meter sections, and third party damage index (tpdi), ...

The local bend is a directed behavior produced by the leech, Hirudo medicinalis, in response to a light touch. Contraction of longitudinal muscles near the touched location results in a bend directed away from the stimulus. We quantify the relationship between the location of touch around the body perimeter and the behavioral output by using video analysis, muscle tension measurements, and elec...
