Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...

Core-Ionization Spectrum of Liquid Water [PDF]

open access: yes, 2023
We present state-of-the-art calculations of the core-ionization spectrum of water. The values of experimentally derived solvation shifts in the core 1sO ionization energy of water vary from -1.3 to -2.8 eV due to difficulties in assessing the effect of ...

Ionizing and Non-ionizing Radiation [PDF]

open access: yes, 2017
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

open access: yesGalaxies, 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.

The physical chemistry of the enigmatic phospholipid diacylglycerolpyrophosphate

open access: yesFrontiers 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.

Doubly and Triply Differential Cross Sections for Single Ionization of He by Fast Au53+ Using a Multi-Body Quasiclassical Model

open access: yesAtoms, 2020
A multi-body multi-center quasiclassical model was used to determine doubly- and triply-differential cross sections following single ionization in 3.6 MeV/amu Au53+ + He collisions.

Electron-Impact Ionization of Heavy Atoms Using the Time-Dependent Close-Coupling Method

open access: yesAtoms, 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.
