... Given two magnets, Gilbert knew that magnetic poles can attract or repel, depending on polarity. ... That is, the end of an iron bar stuck to an S pole of a magnet (south-seeking pole) temporarily becomes an N-pole. ... Gilbert confirmed his guess of temporary ("induced") magnetism by an original experiment (see drawing). ... Under the influence of the terrella, each became a temporary magnet with the same polarities, and the temporary poles of each bar repelled those of the other one. ...

... 2 Magnetic Field . ... A magnetized bar has its power concentrated at two ends, its poles ; they are known as its north (N) and south (S) poles, because if the bar is hung by its middle from a string, its N end tends to point northwards and its S end southwards. ... That flow became known as an electric current . ... An electric current produced a magnetic force! ... The fundamental nature of magnetism was not associated with magnetic poles or iron magnets, but with electric currents . ...

... Directives | ... Apache HTTP Server Version 2.4 . ... The most important directives used to control this MPM are ThreadsPerChild , which controls the number of threads deployed by each child process and MaxRequestWorkers , which controls the maximum total number of threads that may be launched. ... Two directives set hard limits on the number of active child processes and the number of server threads in a child process, and can only be changed by fully stopping the server and then starting it again....

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

The User and Group directives are used to set the privileges of the Apache child processes. ... The child process creates multiple threads to serve requests. ...

... Release Note for patch to SAS 6.5.0 =================================== Carlos Gabriel Eduardo Ojero XMM-Newton SOC A small patch to change the way the EMOSn_REDIST CCFs are used, has to be issued. ... This goes together with a set of calibration files. ... A large number of SAS users synchronize their calibration repositories to get automatically new released calibration files, but have not updated to SAS 6.5.0., which causes a problem. ...

Next: E-Science Up: C.S. Jeffery Previous: Subluminous B Stars Contents . Following core-helium burning, a low-mass star expands to become a giant as it consumes its final reserves of nuclear fuel and, subsequently, contracts to become a white dwarf. ... Our research on extreme helium stars and other post-AGB stars is directed towards understanding these processes and towards developing models of stellar evolution that fit the observations. ...

Most of these images were obtained by Mike Bessell, Michelle Buxton, Hwankyung Sung, Ralph Sutherland and Bob Watson at SSO using a 2Kx2K Site CCD behind a Nikon or Hasselblad lens or directly on the 1m telescope. A few images are from the Hubble Space Telescope. Some of the M42 images were obtained with the KPNO 1m and ESO NTT telescope. One image is a mosaic of IRAS images. ...

... MSSSO is part of a collaboration developing a wide field imaging CCD mosaic (WFI). As part of this project, we have developed a GUI based pipeline tool that is an integrated part of MSSSO's CICADA data acquisition environment and processes CCD FITS images as they are acquired. ... This pipeline tool was originally developed for the Wide Field Imager (WFI) being developed jointly by MSSSO , AAO and the University of Melbourne , but it can be used to process other CCD image data. ...

... On-the-Fly Reprocessing . ... STIS has moved from the On-the-Fly Calibration (OTFC) processing system to the new On-the-Fly Reprocessing (OTFR) system. ... With OTFR, raw data headers are re-built from these pod files, enabling many changes and fixes to be done at this early step, which were impossible with OTFC. ... There will no longer be a column for Used and Best reference files, since you will by default receive the best reference files, and Used becomes meaningless under the OTFR system. ...
