  Aqueous - Wikipedia, the free encyclopedia
Aqueous either pertains to, is related to, is similar to, or is dissolved in water.
An aqueous solution is a solution in which water is the solvent used rather than, for example, alcohol or ether.
Aqueous humor is the transparent fluid occupying the space between the crystalline lens and the cornea of the eye.

 Aqueous humour - Wikipedia, the free encyclopedia
The aqueous humour is the clear, watery fluid that fills the complex space in the front of the eye which is bounded at the front by the cornea and at the rear by the front surface or face of the vitreous humour.
The face of the vitreous humour spans the eye transversely behind the lens, and the aqueous-filled space in front of this is divided by the iris plane into the anterior chamber and the posterior chamber (which, despite its name, is still an anterior structure).
The aqueous humour allows nutrients to circulate to the corneal endothelium and its pressure maintains the convex shape of the cornea.

 Effects of Aqueous Treatment on Albumen Photographs
The results of this study show that any aqueous treatment, be it surface cleaning or immersion, increases the cracking of the albumen layer while not substantially altering albumen yellowing.
Since aqueous treatment was thought to have the greatest potential impact on areas of minimum image density, colorimetry emerged as the measuring tool of preference.
The aqueous surface cleaning of an extremely soiled print, for example, may be an instance when the benefit of greater image clarity outweighs the damage created by increased overall cracking.

Heated, aqueous parts washers have been found to be effective for many parts cleaning applications and are available as sink-type units and as automatic spray wash ("dishwasher") units.
By using aqueous (non-solvent) parts washing, the amount of VOC emissions is reduced.
Some aqueous units have oil skimmers and coarse filtration, which will remove suspended solids, increasing the likelihood that the spent solution may be disposed as non-hazardous waste.

 98 Aqueous Shunts - 510(k) Submissions
An aqueous shunt is defined as an implantable device intended to reduce intraocular pressure in the anterior chamber of the eye.
Aqueous shunts that have a long history of clinical usage may be able to satisfy this recommendation with published clinical studies that demonstrate the safety and effectiveness of the device.
New aqueous shunts (i.e., new materials, new designs) should be evaluated with a clinical investigation developed with the protocol elements provided in Appendix C or an equivalent protocol which has similar statistical power to detect clinically significant differences between the test and the control populations.

 Aqueous humor
Aqueous humor drains out of the eye through the trabecular meshwork.
Aqueous humor is returned into the bloodstream through a tiny channel (Schlemm's canal) located under the trabecular meshwork.
Aqueous humor is produced by and removed from the eye at a constant rate [about 1 tsp(5 mL) per day] to maintain a constant pressure in the front (anterior) chamber of the eye.

 Technical Issues and Aqueous Cleaning Systems
More recently, aqueous cleaning processes have been shown in the published literature to be a technically feasible alternative to solvents that are ozone-depleting or have other undesirable characteristics.
The aqueous solution was investigated as a replacement for a petroleum distillate solvent and a naphthalene-based solvent that had been used to replace the original TCA vapor degreaser.
Aqueous cleaning installations were found in the literature to rely heavily on the mechanical properties of the system, referred to as "impingement" by Rowney.

 Accurate Prediction of Aqueous Solubility
For a potential drug to be effective orally, it must dissolve in an aqueous environment and be absorbed by the body.
Aqueous drug solubility is the single largest factor driving passive human absorption via the gastrointestinal tract.
Accurate prediction of aqueous solubility has been a long-sought-after goal among computational chemists: knowledge of a compound's solubility is essential for practical experimental reasons and to assess the possibility of passive gastrointestinal absorption.

 Direct determination of unbound lipophilic ligands in aqueous solutions   (Site not responding. Last check: 2007-10-07)
It is important to realize that the limited solubility in aqueous solutions of such compounds prohibits the use of solutions lacking binding proteins for the experiments.
Often the lipophilic ligands are added to aqueous solutions dissolved in ethanol, but in such cases nothing is known about the monomer concentration and it is likely to exceed the physiological concentration.
In a third study (14) all the difficulties of the classical phase partition method is discussed and it is suggested that concentration values in the low range may also be obtainable by this method.
