The radio properties of powerful extended radio sources may be used to estimate the ambient gas density in the vicinity of radio lobes. A sample of 27 radio lobes from 14 radio galaxies and of 14 radio lobes from 8 radio loud quasars was constructed using sources from the published literature with suucient radio information to allow an estimate of the ambient gas density. The ambient gas densit...
The thermodynamic functions such as enthalpy (H), Gibbs free energy (G) and entropy (S) ofPyrazole was theoretically studied at 5 different temperatures 25, 30, 35, 40 and 45°C by usingGussian o3, software. First, the structural optimization of isolated Pyrazole was done in the gas phaseby appling the Density Functional Theory (B3LYP) level with 3-21G, 6-31G and 6-31+G(d) basissets. Moreover, v...
In this study, gas evolution in a vertical electrochemical cell is investigated numerically with a modified two-fluid model. The mathematical model involves solution of separate transport equation for the gas and liquid phases with an allowance to inter-phase transfer of mass and momentum. The governing equations are discreted via the finite volume technique and then are solved by ...
The method for the extinction correction based on the gas column density is tested. A positive correlation is found between the total gas column density and the extinction estimated using amodel based on energy conservation (‘frequencyconverter model’). Assuming a Solar Neighbourhood opticaldepth–to–gas ratio, extinction is predicted from the gas column density using a radiative transfer model ...
This paper is a density functional theory (DFT) calculation of intramolecular proton transfer (IPT) in 6-hydroxypicolinic acid (6HPA, 6-hydroxypyridine-2-carboxylic acid) tautomeric forms. The transition state for the enol-to-keto transition is reported in the gas phase and in four different solvents. The planar and non-planar dimer forms of 6HPA keto and enol, respectively, were also studied i...
چگالی سنجی به وسیله پرتوگاما به عنوان یک روش غیرمخرب و توانمند برای اندازه گیری نسبت حجمی گاز و رژیم جریان در لوله های شامل جریانهای دو فازی و چند فازی مورد استفاده قرار می گیرد. اساس کار در این روش اندازه گیری تضعیف پرتوگاما می باشد. هدف این پروژه این است که با استفاده از یک چشمه گامای کم انرژی (241 am) نسبت حجمی گاز و رژیم جریان محاسبه گردد. محدوده نسبت حجمی گاز را برای رژیم های جریان bubbl...
We report on the use of a novel technique to measure the gas density from a pulsed gas jet. Deuterium gas is fully ionized with an intense picosecond laser, and the resulting electron density is measured by interferometric probing with a second picosecond pulse. We have applied this technique to characterize a cryogenically cooled, high-density gas jet.
the existing measuremenjs of the viscosity of gaseous systems can be extended if use is made of statistical mechanics. in this work, we confine ourselves to the measurements of the viscosity of multicomponent mixtures of low-density gases. the method is applied to one sample of natural gas.
The influence of outer top gas injection on the scrape-off layer (SOL) density and ion cyclotron range of frequency (ICRF) coupling has been studied in ASDEX Upgrade (AUG) L-mode plasmas for the first time. The three-dimensional (3D) edge plasma fluid and neutral transport code EMC3-EIRENE is used to simulate the SOL plasma density, and the 3D wave code RAPLICASOL is used to compute the ICRF co...
We quantify the notion of a dense soliton gas by establishing an upper bound for the integrated density of states of the quantum-mechanical Schrödinger operator associated with the Korteweg-de Vries soliton gas dynamics. As a by-product of our derivation, we find the speed of sound in the soliton gas with Gaussian spectral distribution function.
