Background: The potential hazards of exposure to radiation from radon have been of great concern worldwide, as it is associated with an increased risk of lung cancer. Radon (222Rn) and its progeny are the main sources of radioactivity in the environment. The half-life of 222Rn (3.82 days) is long enough for it to diffuse into and build up in homes. 220Rn or thoron from the 232Th series, and 219...

The operator Jm p (λ, )f (z) was studied by Srivastava et al. [3] and Aouf et al. [4]. From (1.2) and (1.3), we observe that J−m p (λ, )f (z) = Im p (λ, )f (z)(m > 0), so the operator Jm p (λ, )f (z) is well-defined for l ≥ 0, l ≥ 0, p Î N and m Î Z = {..., -2, -1,0,1,2,...}.

Considerations on the MoschopouleanComments Sophocles’ “Electra” vv. 823–825”: In this article, I am looking into question of what scholia theByzantine triad Sophocles by Manuel Moschopoulos contain understanding possibly them entails.In particular, consider comments Electra (vv. 823–825), which are preserved in so-...

In the search of new organometallic precursors, this contribution describes a convenient synthesis to obtain ferrocene-based sulfonyl diamine derivatives. The [(η5-C5H4SO2NH-CH2-CH2-NH2)Fe(η5-C5H5)] (1) and [(η5-C5H4SO2NH-C6H4-NH2)Fe(η5-C5H5)] (2) compounds were prepared by reaction between (η5-C5H4SO2Cl)Fe(η5-C5H5) respective precursor: ethylenediamine or p-phenylenediamine in good yield...
