. When you enter a command it invokes a program. While this program is running it is called a process . Although there is only one copy of a program, any number of processes can be invoked which run this program. There are several commands which allow you to manage the processes that belong to you. You cannot do anything with processes belonging to other users. Running processes in the foreground . Running processes as background jobs . Managing background jobs . Monitoring processes . Killing a process .

BACKGROUND . ... Electron bombarded silicon (EBS) gain makes the CCD interesting for keV electron detection. Ionizing particles absorbed in silicon create electron-hole pairs at the average rate of one per 3.64 eV incident energy. ... The variance in the number of electron-hole pairs created is given by the Fano factor for silicon (.1-.2) times the number of pairs created. When we use a CCD as a detector of ionizing particles, we would like to collect all of the electrons created. ...

... Iron abundance in the atmospheres of components of the binary system 41 Draconis . ... 5B Iron abundances, FeI and FeII lines equivalent widths, and microturbulence velocities were found for the components of a highly eccentric spectroscopic and interferometric binary system 41 Dra from high resolution spectra obtained close to the periastron. Weighted mean values of iron abundances in the atmospheres are lgN(Fe) = 7.66 ± 0.03 and lgN(Fe) = 7.72 ± 0.03 for the component a and b, correspondingly. ...
