Systematic Studies on the Inter-Combination Lines of He-like to O-like Argon

Abstract

Multiconfiguration Dirac-Fock calculations have been carried out in the Extended Optimal Level (EOL) scheme on the energies, transition probabilities and weighted absorption oscillator strengths of intercombination lines of highly ionized argon. The calculations have been carried out in intermediate coupling with empty K shell, varying degrees of ionization in the L shell and open outer shells. The radiative transition rates have been calculated in both length and velocity gauges and an analysis on the accuracy of the orbital functions used in this work has been attempted by comparing the length form and velocity form transition rates.

New Aspects in Sustained Drug Release Formulations

“…The resulting oxidized cellulose esters are soluble in aqueous alkaline solutions, water, and a variety of organic solvents. Cellulose ethers were also used in many sustained release formulations as blends along with other carriers, in order to create different release profiles [13][14][15]. Celluloses and glyceryl behenate are used for doxazosin mesylate to prepare a sustained-release tablet for which drug release rates maintain constant for 8 hr.…”

“…Several methods are used towards this direction, including encapsulation, coating, emulsion, and the use of liposomes. Amongst these, the polymeric film coating is the most [1, [10][11][12][13][14][15][16][17][18][19] popular one ( Table 2). A coated dosage form enables the prolonged and precise release of drug with good reproducibility.…”

Properties of the K_{α} X-Ray Transitions in Highly Ionized Chlorine

“…The virtual set was varied in a systematic way by increasing the principal quantum number n by one without imposing restrictions on the orbital quantum number. Earlier calculations [22] indicate that the set that could be handled without any diculty was up to n = 4. Also, for congurations with more than four electrons, the number of CSFs generated was very large for double excitation and we could not carry out our RCI calculations due to storage limitations.…”
