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.

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 ...

On resistive magnetohydrodynamic equilibria of an axisymmetric toroidal plasma with flow [PDF]

open access: yes, 1999
It is shown that the magnetohydrodynamic equilibrium states of an axisymmetric toroidal plasma with finite resistivity and flows parallel to the magnetic field are governed by a second-order partial differential equation for the poloidal magnetic flux ...

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.

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.

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 ...

Monodisperse hard rods in external potentials [PDF]

open access: yes, 2015
We consider linear arrays of cells of volume $V_\mathrm{c}$ populated by monodisperse rods of size $\sigma V_\mathrm{c}$, $\sigma=1,2,\ldots$, subject to hardcore exclusion interaction. Each rod experiences a position-dependent external potential. In one

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 .

Local and Distortional Buckling of Axially Loaded Cold Rolled Sigma Profiles [PDF]

open access: yesActa Mechanica et Automatica, 2016
Abstract In this paper the local and distortional buckling analyses of axially loaded cold-rolled channel and sigma profiles were performed. The critical buckling load was computed by solving the linear eigenvalue problem for different numerical models using Finite Element Method and simplified formulas implemented in Eurocode and ...
