The broad line region of AGN: Kinematics and physics [PDF]
Serbian Astronomical Journal, 2006 In this paper a discussion of kinematics and physics of the Broad Line Region (BLR) is given. The possible physical conditions in the BLR and problems in determination of the physical parameters (electron temperature and density) are considered. Moreover,

Ionization of Hydrogen in the Solar Atmosphere
Journal of Astronomy and Space Sciences, 2021 The ionization degree of hydrogen is crucial in the physics of the plasma in the solar chromosphere. It specifically limits the range of plasma temperatures that can be determined from the Hα line.

Stark Broadening of Zn III Spectral Lines
Universe, 2022 Stark widths for spectral lines within 24 multiplets of Zn III singlets and triplets have been calculated using modified semiempirical method for an electron density of 1017 cm−3 and temperatures from 5000 K up to 100,000 K.

A Process Calculus of Atomic Commit
Electronic Notes in Theoretical Computer Science, 2004 AbstractThis article points out a strong connection between process calculi and atomic commit. Process calculus rendezvous is an abstract semantics for atomic commitment. An implementation of process-calculus rendezvous is an atomic commit protocol. Thus, the traditional correctness properties for atomic commit are entailed by a bisimulation proof of a

Stark Broadening of Al IV Spectral Lines
Universe, 2023 Stark widths for 23 transitions in Al IV have been calculated by employing the modified semiempirical method. The results are obtained for an electron density of 1017 cm−3 and temperatures from 10,000 K to 160,000 K.
