Shining a light on galactic outflows: photoionized outflows [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2016
We study the ionization structure of galactic outflows in 37 nearby, star forming galaxies with the Cosmic Origins Spectrograph on the Hubble Space Telescope. We use the O I, Si II, Si III, and Si IV ultraviolet absorption lines to characterize the different ionization states of outflowing gas. We measure the equivalent widths, line widths, and outflow

Outflow Studies in Children

Archives of Ophthalmology, 1965
There is ample evidence that chronic simple glaucoma has familial tendencies. 1 Investigations by Becker et al 2 and Miller and Paterson 3,4 demonstrated that close relatives and descendants of patients with simple glaucoma have increased values for P o , reduced values for C, and thus elevation of P o /C—all in significant amounts.

Uveoscleral outflow – A review

Experimental Eye Research, 2009
The uveoscleral outflow route was described more than 40 years ago. Part of aqueous leaves the eye through the iris root. The ciliary muscle, and there are large species differences in the fraction of aqueous outflow that leaves the eye through this route. In non-human primates 40-50% of aqueous leaves the eye by the uveoscleral route.

Lacrimal outflow dysgenesis

Ophthalmology, 2004
To evaluate patients with lacrimal dysgenesis.Retrospective, nonrandomized, comparative case series.Fifty patients with lacrimal dysgenesis managed between 1992 and 2003. TESTING/INTERVENTION: The diagnosis of lacrimal outflow dysgenesis was made based on the following criteria: absent or hypoplastic punctum, canaliculus, lacrimal sac, and nasolacrimal

CLINICAL AQUEOUS OUTFLOW

Archives of Ophthalmology, 1953
IN RECENT years considerable knowledge has been added to our understanding of aqueous outflow. Although it had been known for many years that patients with chronic simple glaucoma had a decreased facility (increased resistance) of aqueous outflow,1it is through the recent efforts of Goldmann2and Grant3that these findings have been placed on a more ...

Acetazolamide and Outflow Facility

Archives of Ophthalmology, 1966
The carbonic anhydrase inhibitors are the drugs most useful clinically in reducing aqueous flow and lowering intraocular pressure. 1-3 Their hypotensive effect is greater in the hypertensive eye than in the normal, and in the latter has been reported to be accompanied by a compensatory reduction in outflow facility.

Outflow facility studies in the perfused bovine aqueous outflow pathways

Current Eye Research, 1988
We have recently developed a technique for constant pressure perfusion of the aqueous outflow pathway of the eye. Our preliminary studies, conducted in the calf eye, show surprisingly that the manipulations necessary for preparing the outflow pathways and attached corneoscleral shell for perfusion do not greatly disrupt normal aqueous outflow ...

Models of Molecular Outflows

Astrophysics and Space Science, 1995
In this contribution, I present a broad “historical” review of the various hydrodynamical models that have been considered for explaining molecular outflows, and of their merits and failures when compared with observations. Wind-driven bubbles, viscous jet mixing-layers, and jet bowshocks, are discussed in turn.

Cerebellar and Outflow Tremor

Seminars in Neurology
Abstract Cerebellar and cerebellar outflow tremors are significant movement disorders that pose therapeutic challenges. These tremors result from disruptions in the cerebellothalamocortical network, particularly affecting key nuclei and pathways. The primary clinical manifestation is an intention tremor characterized by low-frequency,
