Iodine-125 (125I) is one of the radioisotopes widely used in radiopharmaceuticals for diagnosis and therapy various cancers. Recent reports indicate that there has been shortages world supply this radioiodine isotope. One absolute requirements good must meet radiochemical purity, which generally to be above 95 %, with an efficiency over 90 %. The previous investigation shows purity low does not...

The aim of this paper is to introduce Reductor, a program that automatically removes unused parts of the source code of valid programs written in the Mercury language. Reductor implements two main kinds of reductions: statical reduction and dynamical reduction. In the statical reduction, Reductor exploits semantic analysis of the Melbourne Mercury Compiler to find routines which can be removed ...

The diagnosis of gearbox faults based on the Fourier analysis of the vibration signal produced from a gear reductor system has proved its limitations in terms of spectral resolution. In this paper, we propose a method for the fault diagnosis of a gear reductor made of two toothed wheels operating at constant conditions. This technique is based on Prony method. The good performances of the propo...

To overcome many-query optimization, control, or uncertainty quantification work loads in reliable gas and energy network operations, model order reduction is the mathematical technology of choice. this end, we enhance model, solver reductor components morgen platform, introduced Himpe et al. [J. Math. Ind. 11:13, 2021], conclude with a mathematically, numerically computationally favorable mode...

A novel spectrophotometric reaction system was developed for the determination of nitrite as well as nitrate in water samples, and was applied to a flow-injection analysis (FIA). The spectrophotometric flow-injection system coupled with a copperised cadmium reductor column was proposed. The detection was based on the nitrosation reaction between nitrite ion and phloroglucinol (1,3,5-trihydroxyb...

Este artículo presenta una aproximación mediante rechazo activo de perturbaciones para controlar, manera indirecta, la temperatura cara fría un módulo termoeléctrico alimentado por convertidor CD-CD tipo reductor. La dinámica del módulo, es vista como perturbación naturaleza desconocida y variante en el tiempo, voltaje salida convertidor. Dicha estimada observador proporcional integral generali...

The nitrate-selective copperised-cadmium (Cu-Cd) reduction reaction coupled directly to the highly sensitive nitrite ion chromatographic detection, produced a more precise method for determination of nitrate than any one of the two conventional methods. A borate buffer solution used in the reduction reaction, in place of the conventional ammonium-EDTA buffer solution, eliminated interferences f...
