Ionization effect of solar particle GLE events in low and\ middle atmosphere [PDF]
Atmospheric Chemistry and Physics, 2011 Using a new reconstruction of the solar proton energy spectra for Ground Level Enhancement (GLE) events, based on fits to measurements from ground-based and satellite-borne instruments covering a wide energy range, we quantitatively evaluate the possible

Atmospheric Pressure Chemical Ionization Is a Suboptimal Ionization Source for Steroids [PDF]
Clinical Chemistry, 2018 To the Editor: Biochemical measurement of steroid hormones is imperative for the diagnosis of adrenocortical carcinoma (ACC).1 The lack of clinical syndromes in over half of patients with ACC prevents the early diagnosis of this malignant disease if appropriate laboratory evaluations are not performed (1, 2).

Ionization in Nova Atmospheres [PDF]
International Astronomical Union Colloquium, 1970 AbstractCalculations on the expansion of novae shells are presented, from which the degree of ionization is obtained using a simplified form of a non-LTE ionization equation. From this, estimates of the time of vanishing of the Balmer absorption spectrum can be made.

Lookup tables to compute high energy cosmic ray induced atmospheric ionization and changes in atmos [PDF]
, 2008 A variety of events such as gamma-ray bursts and supernovae may expose the Earth to an increased flux of high-energy cosmic rays, with potentially important effects on the biosphere. Existing atmospheric chemistry software does not have the capability of
