tracking (RPT) technique has a proven capability to visualize flow fields of multiphase flow systems. The RPT technique is a Lagrangian measurement technique, used to track the movement of a single radioactive tracer by means of detectors to obtain the velocity field of a multiphase flow system ...
The RPT technique is based on considering an isotropic gamma emission pattern. Negative-beta decay provides such gamma emissions. This emission mechanism is characteristic of neutron-rich nuclei. Additionally, following the ALARA safety philosophy, the tracer must be properly active during the experiments...
(ML) logistic regression estimates; therefore to mitigate the bias caused as a consequence of the insufficiency of events, Firth’s penalized likelihood [12] was applied. This technique was a solution used to minimize the analytical bias caused by complete separation, small samples, and rare ...
In contrast to amino acids such as leucine [22], the essential amino acid phenylalanine (Phe) is commonly used as a tracer because it does not influence protein synthesis [18] when injected in high amounts, fulfilling the fourth criterion named by Fraser and Rogers (2007) [2]. Phe, howev...
For RPT technique calibration, a fully automatic calibration system was used to locate the radioisotope particle at different coordinates (r, θ, z) inside the column by fixing the tracer particle at the end of the rod. The main purpose of this unit was to generate a dataset of calibration ...
Versions Notes Abstract Studies of leaching of vitrified simulated high-level radioactive waste (HLW) evidence that most of actinides or their simulators enter leaching water in a colloidal form. In this paper, we consider a mechanism of colloid-facilitated migration of radionuclides from an undergro...
Good biodistribution and high accumulation in the infected region make these complexes suitable for applications as radiotracer for infection imaging [88,89,90,91,92,93,94,95,96]. Doxycycline, another antibiotic used for the treatment of several infections and part of the tetracycline class, has ...
However, one of the potential challenges in applying this depth estimation technique in the field is the time required to move a single gamma detector across the scan area. This can be eliminated by using a square array of gamma detectors since each detector and its shielding covers only a re...
