Novel Diversion Structure for Supercritical Flow

Journal of Hydraulic Engineering, 2013
AbstractIn urban drainage systems, it is usually necessary to split the storm water discharge among different sewer branches because of limited flow capacity of either hydraulic structures or sewer lines. For this purpose, sewer sideweirs and leaping weirs are generally used as diversion overflow structures.

Flow diversion jet: A dangerous mechanism in the flow diversion treatment of giant intracranial aneurysms

Interventional Neuroradiology, 2023
Background Cerebral hyperperfusion syndrome (CHS) occurs after the restoration of blood flow to a previously low-flow, low-pressure region of the cerebral vasculature, which subsequently responds with chronic compensatory vasodilation, leading to a dysregulated state.

Flow diversion of fusiform intracranial aneurysms

Neurosurgical Review, 2020
Fusiform aneurysms are less common than saccular aneurysms, but have higher associated mortality and rebleeding rates. Recently, flow diversion has emerged as a possible treatment option. The purpose of this study was to determine the safety and efficacy of the Pipeline Embolization Device (PED) for the treatment of ruptured and unruptured fusiform ...

Flow-Diversion for Ophthalmic Segment Aneurysms

Neurosurgery, 2015
The use of flow-diversion to treat ophthalmic segment aneurysms (OSA) has not been well evaluated.To assess the visual outcomes, the obliteration rate, and the need for retreatment of OSA treated by the pipeline embolization device (PED).Patients who underwent treatment with PED for OSA from 2009 to 2014 were selected and retrospectively reviewed ...

Flow Diversion and the Almighty Dollar

World Neurosurgery, 2014
.S. health care is too expensive and its quality too inconsistent. Patients have greater deductibles now U than ever before. The public is learning there are no demonstrable correlations between cost of service and quality (in fact, the opposite may often be true). Although there is no debate that health care costs have skyrocketed, there is legitimate

Cultural Diversity, Citizenship, Migration Flows

Il diritto dell'economia : 79, 3, 2012, 2012
The article examines the relationship between the concept of citizenship and that of multiculturalism, focusing in particular on overcoming the traditional view: that of considering the concept of citizenship as defined by the boundaries of a nation state.

Species diversity and interspecific information flow

Biological Reviews
ABSTRACTInterspecific information flow is known to affect individual fitness, population dynamics and community assembly, but there has been less study of how species diversity affects information flow and thereby ecosystem functioning and services.

Tourniquet parent artery occlusion after flow diversion

Journal of NeuroInterventional Surgery, 2017
BackgroundThe Pipeline Embolization Device (PED) is increasingly used for both on- and off-label purposes for treatment of intracranial aneurysms. The device gradually slows flow of blood into the aneurysm, but the high metal coverage of PED promotes endothelialization of the device. Occasionally, this leads to in-stent stenosis that is clinically well
