Symmetric Atom–Atom and Ion–Atom Processes in Stellar Atmospheres [PDF]

open access: yesAtoms, 2017
We present the results of the influence of two groups of collisional processes (atom–atom and ion–atom) on the optical and kinetic properties of weakly ionized stellar atmospheres layers.

Computational Characterization of Astrophysical Species: The Case of Noble Gas Hydride Cations

open access: yesFrontiers in Chemistry, 2021
Theoretical–computational studies together with recent astronomical observations have shown that under extreme conditions in the interstellar medium (ISM), complexes of noble gases may be formed.

Comparative performance of activated sludge and aerobic granular sludge sequencing batch reactors for removing metalloid SeIV/VI oxyanions

open access: yesJournal of Hazardous Materials Letters, 2021
Biotransformation of soluble selenite (SeIV) and selenate (SeVI) to biomass-associated Se0 (Bio-Se) provides a solution for mitigating Se pollution coupled to securing scarce element.

Stark Width Data for Tb II, Tb III and Tb IV Spectral Lines

open access: yesData, 2021
A dataset of Stark widths for Tb II, Tb III and Tb IV is presented. To data obtained before, the results of new calculations for 62 Tb III lines from 5d to 6pj(6,j)o, a transition array, have been added.

Ionization of Hydrogen in the Solar Atmosphere

open access: yesJournal of Astronomy and Space Sciences, 2021
The ionization degree of hydrogen is crucial in the physics of the plasma in the solar chromosphere. It specifically limits the range of plasma temperatures that can be determined from the Hα line.

Stark Broadening of Zn III Spectral Lines

open access: yesUniverse, 2022
Stark widths for spectral lines within 24 multiplets of Zn III singlets and triplets have been calculated using modified semiempirical method for an electron density of 1017 cm−3 and temperatures from 5000 K up to 100,000 K.

Theoretical Stark Broadening Parameters for UV–Blue Spectral Lines of Neutral Vanadium in the Solar and Metal-Poor Star HD 84937 Spectra

open access: yesAtoms, 2020
Using Griem’s semi-empirical approach, we have calculated the Stark broadening parameters (line widths and shifts) of 35 UV–Blue spectral lines of neutral vanadium (V I).

Fungal infections: Pathogenesis, antifungals and alternate treatment approaches

open access: yesCurrent Research in Microbial Sciences, 2022
Increasing incidence of fungal infections of recent times requires immediate intervention. Fungal infections are seldom construed at initial stages that intensify the severity of infections and complicate the treatment procedures. Fungal pathogens employ

A 3D STOCHASTIC MODEL FOR GEOMETRICAL CHARACTERIZATION OF PARTICLES IN TWO-PHASE FLOW APPLICATIONS

open access: yesImage Analysis and Stereology, 2018
In this paper a new approach to geometrically model and characterize 2D silhouette images of two-phase flows is proposed. The method consists of a 3D modeling of the particles population based on some morphological and interaction assumptions.
