‘Solomon’s Bottle’: a Glass Bottle in Tehran and Abbasid Glass Floors in Mesopotamia and the Levant
The article discusses a scarcely known medium of architectural decoration in Abbasid palaces, transparent glass tiles, and reports on the discovery of the largest known assemblage of fragments of such tiles in Tehran, in a bottle of the Glassware and Ceramics Museum of Iran. The first part deals with the visual and material aspects of the use of transparent glass tiles, based on archaeologica...
متن کاملA Siphon Hypothesis Goes Down the Tube
So-called neurovascular coupling reflects local blood flow changes that accompany neuronal activity. Not only is this a homeostatic metabolic mechanism, but it also serves as the basis for functional brain imaging. The theory goes that glia cells siphon activity-generated extracellular potassium ions to glial endfeet abutting small blood vessels, leading to vessel relaxation. Not so, say Metea ...
متن کاملCorrigendum: The height limit of a siphon
We wish to acknowledge a related 1995 experiment performed by Andrew K Fletcher (http://inclinedbedtherapy. com), in which a 48 m length of 6 mm bore tubing, filled with degassed water was lifted 24 m vertical against Brixham Cliffs. A 50 ml bolus of coloured saline solution in the middle of the 48 m tubing was introduced prior to the tubing being raised to 24 metres vertical by its centre as a...
متن کاملThe height limit of a siphon
The maximum height of a siphon is generally assumed to be dependent on barometric pressure-about 10 m at sea level. This limit arises because the pressure in a siphon above the upper reservoir level is below the ambient pressure, and when the height of a siphon approaches 10 m, the pressure at the crown of the siphon falls below the vapour pressure of water causing water to boil breaking the co...
متن کاملShip in a Bottle
We ran a fluid simulation [4] using the simplified mesh. At first we ran a very high resolution simulation that gave us nice waves but we realized that the big waves did not suit the scene. Moreover it was giving us small scale features while we were more looking to get large scale waves. Hence we ran a course simulation where a source seed water in a sine wave pattern. This gave us nice bulk w...
