The ionization of the diffuse ionized gas
The Astrophysical Journal, 1994 The diffuse ionized gas (DIG), responsible for producing the faint but pervasive H(sub alpha), requires 15% of the power of all Galactic O stars for its ionization. No other source of ionization seems practical. The spectrum is strong in low stages of ionization (N II, SII), weak in (O III), and very weak in (O I) lambda 6300, at least in one well ...

Ionizing and Non-ionizing Radiation [PDF]
, 2020 This chapter describes ionizing radiation and non-ionizing radiation, ways to measure it in the environment, describes the potential health effects from chronic and acute exposures as well as a discussion addressing pregnancy concerns. Background radiation from both sources are described in relation to occupational or public exposure limits and how ...

Ionization-Gasdynamic Simulations of Wind-Blown Nebulae around Massive Stars
Galaxies, 2022 Using a code that employs a self-consistent method for computing the effects of photo-ionization on circumstellar gas dynamics, we model the formation of wind-driven nebulae around massive stars.

Performance of a corona ion source for measurement of sulfuric acid by chemical ionization mass spectrometry [PDF]
, 2010 The performance of an ion source based on corona discharge has been studied. This source is used for the detection of gaseous sulfuric acid by chemical ionization mass spectrometry (CIMS) through the reaction of NO−3 ions with H2SO4.

The physical chemistry of the enigmatic phospholipid diacylglycerolpyrophosphate
Frontiers in Plant Science, 2012 Phosphatidic acid (PA) is a lipid second messenger that is formed transiently in plants in response to different stress conditions, and plays a role in recruiting protein targets, ultimately enabling an adequate response.

Electron-Impact Ionization of Heavy Atoms Using the Time-Dependent Close-Coupling Method
Atoms, 2021 The time-dependent close-coupling method has been recently applied to calculate electron-impact direct ionization cross sections for the Kr, W, and Pb atoms. An overview is presented for these three heavy neutral atom systems.
