Simulation of PD Optical Signal Mechanism Based on FCT Algorithm

open access: yesShanghai Jiaotong Daxue xuebao, 2020
The flux-corrected transport (FCT) algorithm is used to simulate the two-dimensional planar needle-plate structure of the positive streamer model and the partial discharge process of tip defects. The variations in electron density, net charge density and

Validation of a new spectrometer for noninvasive measurement of cardiac output [PDF]

open access: yes, 2004
Acetylene is a blood-soluble gas and for many years its uptake rate during rebreathing tests has been used to calculate the flow rate of blood through the lungs (normally equal to cardiac output) as well as the volume of lung tissue.

Propagation of the pulsed electron beam of nanosecond duration in gas composition of high pressure [PDF]

open access: yes, 2015
This paper presents the results of the investigation of the propagation of an electron beam in the high-pressure gas compositions (50, 300, and 760 Torr): sulfur hexafluoride and hydrogen, sulfur hexafluoride and nitrogen, sulfur hexafluoride and argon ...

Laboratory simulation of the formation of an ionospheric depletion using Keda Space Plasma EXperiment (KSPEX)

open access: yesAIP Advances, 2017
In the work, the formation of an ionospheric depletion was simulated in a controlled laboratory plasma. The experiment was performed by releasing chemical substance sulfur hexafluoride (SF6) into the pure argon discharge plasma. Results indicate that the

The Decomposition Products of Sulfur Hexafluoride (SF6) with Metals Dissolved in Liquid Ammonia

open access: yesInorganics, 2017
Sulfur hexafluoride is a highly chemically inert gas with several important industrial applications. It is stable against fused alkali, oxygen and ammonia, even at several hundred degrees Celsius. In this work, the reactions between metals (Li–Cs, Sr, Ba,

Beef Steers and Enteric Methane: Reducing Emissions by Managing Forage Diet Fiber Content

open access: yesAnimals, 2023
Understanding the methane (CH4) emissions that are produced by enteric fermentation is one of the main problems to be solved for livestock, due to their GHG effects. These emissions are affected by the quantity and quality of their diets, thus, it is key

Accelerator Testing of the General Antiparticle Spectrometer, a Novel Approach to Indirect Dark Matter Detection [PDF]

open access: yes, 2005
We report on recent accelerator testing of a prototype general antiparticle spectrometer (GAPS). GAPS is a novel approach for indirect dark matter searches that exploits the antideuterons produced in neutralino-neutralino annihilations.

The increasing atmospheric burden of the greenhouse gas sulfur hexafluoride (SF6)

open access: yesAtmospheric Chemistry and Physics, 2020
. We report a 40-year history of SF6 atmospheric mole fractions measured at the Advanced Global Atmospheric Gases Experiment (AGAGE) monitoring sites, combined with archived air samples, to determine emission estimates from 1978 to 2018.
