Sulphur content estimation of Venezuelan heavy oil by fast neutron and gamma transmission technique
Journal of Radioanalytical and Nuclear Chemistry, 2017A compact and modern equipment for implementing the fast neutron and γ-ray transmission technique (FNGT) has been developed in order to estimate the sulphur content of crude oil. FNGT is employed for non- destructive analysis of different kinds of samples.

SummaryIn this paper, the performance of transmission techniques on the fixed‐gain amplify‐and‐forward–based asymmetric radio frequency/free space optical (RF/FSO) communication system is studied. The RF link and FSO link are, respectively, modeled by the Nakagami‐m and Gamma‐Gamma fading channels under the effect of zero boresight and non‐zero ...

Abstract The use of dual energy γ-ray transmission techniques to determine the concentration of a higher atomic number (Z) component in a lower Z matrix is investigated. Examples discussed are the determination of lead in lead-zinc ore, iron in high-grade iron ore, uranium in solution, and ash in coal. These examples are considered in relation to the

This paper focuses on the fluid-fluid, fluid-air interface level detection and density determination by gamma scattering method and intercomparison with transmission (gammatography) technique. The Monte Carlo (MC) numerical simulation of the scattering phenomena is done using the MCNP code. The obtained accuracies and resolution of the level detections

Abstract Quality of fluidization is an important criterion for efficient heat and mass transfer in gas–solid fluidized beds. Knowledge of voidage distribution in fluidized bed is essential when exothermic reactions are carried out in fluidized beds.

Precipitates of the ordered L1(2) gamma' phase (dispersed in the face-centered cubic or FCC gamma matrix) were imaged in Rene 88 DT, a commercial multicomponent Ni-based superalloy, using energy-filtered transmission electron microscopy (EFTEM). Imaging was performed using the Cr, Co, Ni, Ti and Al elemental L-absorption edges in the energy loss ...

Abstract Void fraction simulating stratified air–water flow in cylindrical tubes of different radii was measured using transmission and scattering of gamma rays. A simple experimental set-up using 137 Cs γ-ray point source of 10 μCi and NaI(Tl) detector was used.
