... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

... In order to disentangle the effects of different climate variables on tree-ring growth rates of different species, and to explore the possibility that more than one species could improve the accuracy of the reconstructions of climate using tree rings, a methodical study of trees in close proximity to the Armagh Observatory climate station was initiated together with Ana Maria Garc?a Su?rez, and continued as part of the latter's PhD thesis with John Butler and Professor Mike Baillie (QUB). ...

... Gauging the impact of executing science program across different COS/FUV lifetime positions . ... Changing Programs & Resolving Problems . ... The first such move occurred on 23 July 2012, when the COS FUV spectrum was moved to the COS FUV Lifetime Position 2 (LP2). ... It now appears that the move to COS/FUV Lifetime Position 3 will not occur until early 2015, and so a substantial fraction of Cycle 22 observationsare likely to occur at the COS FUV lifetime position 2, prior to the change. ...

Plasma is sometimes called "the fourth state of matter", beyond the familiar three--solid, liquid and gas. It is a gas in which atoms have been broken up into free-floating negative electrons and positive ions , atoms which have lost electrons and are left with a positive electric charge. ... The fluorescent lamp , widely used in the home and at work, contains plasma (main constituent, mercury vapor) which is heated and agitated by electricity, from the power line to which the lamp is connected. ...

... Two files from two exposures (even from different observations or instruments) are taken as input. These may be EPIC event lists or two other additional files (attitude files, orbit files etc [see comments]). ... Warnings are given when the event files are deemed not entirely compatible (i.e. their INSTRUME or FILTER keywords are different). ... Given here is a summary of the current conditions whereby event files (or parts thereof [blocks/columns etc]) are or are not merged. ...

... Bojan Nikolic web pages (r. 329) . ... Using high-resolution three-dimensional realisations of turbulent fields, we investigate the limits on achievable performance of atmospheric phase correction using water-vapour radiometers arising from following effects: the incoherent measurement of power from water by the radiometers (in contrast to coherent detection of the astronomical signal); the different tapers of the response patterns of the astronomical and radiometer receivers; and, the ...
