The notion of ions first arose in chemistry. In the 19th century it was well known that water in which salts were dissolved (or acids, or bases) conducted electricity, and that an electric current could separate such dissolved materials into their components. ... In 1898 Ernest Rutherford noted that the radiation seemed to contain two electrically charged components of opposite signs, steered by a magnet in opposite directions--positive "alpha rays" and negative "beta rays." ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... We give evidence that lower pressure model chromospheres can alos reproduce the Balmer line profiles, but give Lyman surface fluxes overestimated by more than an order of magnitude. ... We obtain the Paschen lines in emission and Paschen decrements as large as 41 for Pa$_{\beta}$. ... Formation of all Hydrogen series is collisionally controlled and takes place in a rather thin layer at the top of the chromosphere (Balmer, Paschen, and Brackett) or in the transition region (Lyman). ...

UV Solar Blind, Low-Light Level Sensors . ... The filters can be easily optimized for the spectral characteristics of individual sensors. ... When combined with ultra-low noise, UV optimized, back-illuminated CCD sensors, which have been demonstrated to have better than 70 percent quantum efficiency, and readout noise levels of less than 3 electrons at moderate bandwidths, this new filtering technology allows, for the first time, "megapixel" UV solar blind sensors with unparalleled sensitivity. ...

... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

. You can compare any two versions of a file that is under the control of SCCS with the sccsdiff command: /usr/sccs/sccsdiff -r version -r version s. filename . Using this command produces a line by line difference between the two versions of the file. Results are shown in the same format as that produced by the diff command. Examples .
