Estimated desert-dust ice nuclei profiles from polarization lidar: methodology and case studies [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
A lidar method is presented that permits the estimation of height profiles of ice nuclei concentrations (INC) in desert dust layers. The polarization lidar technique is applied to separate dust and non-dust backscatter and extinction coefficients.

Statistical Analysis of Properties of Technological Charge and Manufacturing Tolerance of Thin-Walled Sections in Process of Multi-Workstations Roller Bending [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
The studied collecting electrodes for electrostatic precipitators are cold-rolled formed. Here Sigma 750 open section was manufactured of DC01 steel grade. Length of the electrodes ranged from 8 to 13 meters, all were thin-walled of 1.5 mm.

Use of COSMO-SAC to Determine the Activity Coefficient and Predict Phase Equilibrium of Binary Systems Involving Methanol, Glycerol and Water

open access: yesChemical Engineering Transactions, 2015
With advances in computational chemistry, phase behavior predictions without any experimental data are becoming possible. Models based on COSMO (COnductor-like Screening MOdels) are viable alternatives to group-contribution methods.

F-region Pedersen conductivity deduced using the TIMED/GUVI limb retrievals [PDF]

open access: yesAnnales Geophysicae, 2006
As a proxy of the Rayleigh-Taylor instability growth rate for equatorial plasma bubbles, we investigate the flux-tube integrated F-region Pedersen conductivity (ΣPF) using the electron density profiles (EDPs) provided by the Global Ultraviolet ...

Comparing accretion disk profiles of Bogush–Galt’sov naked singularity and Kerr black hole

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
It is well known that the Einstein-scalar system of general relativity can in principle yield non-unique exact spinning naked singularities, which lead to unique Kerr black hole when the scalar field is switched off.

Unraveling the Complexity of Dwarf Galaxy Dynamics: A Study of Binary Orbital Motions

open access: yesThe Astrophysical Journal, 2023
We investigate the impact of binary orbital motions on the dynamical modeling of dwarf galaxies with intrinsic line-of-sight velocity dispersions ( ${\sigma }_{{v}_{r}}$ ) of 1–9 km s ^−1 .

COSMO prediction of siloxane compounds absorption on type 3 and type 5 deep eutectic solvents

open access: yesChemical Engineering Journal Advances, 2023
This study reports a Conductor-like Screening MOdel for Real Solvents (COSMO-RS) prediction for 151 type 3 (polar) and type 5 Deep Eutectic Solvents (DES, non-polar) for absorption of hexamethyldisiloxane, octamethyltrisiloxane ...

Profiles of relative permittivity and electrical conductivity from unsaturated soil water content models

open access: yesAnnals of Geophysics, 2016
A mathematical model of water diffusion in the vadose zone has been implemented for different types of soil textures in order to determine the soil water content (SWC) profiles in dependence of depth and time.

Surface tension data of n-propane, n-octane and n-dodecane from nucleation simulations

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2018
The Classical Nucleation Theory (CNT) has been a dominant model in understanding the self-assembly of new thermodynamic phases. CNT provides significant explanations to processes such as aerosol formation and cloud condensation.
