“…The kinetic method has been developed since the 1950s, and until nowadays it has a special interest which can be a credit to the progress made in the principles, in understanding the chemicals and instrumentation and in the analytical applications (8). The kinetic spectrophotometric methods offer many advantages over traditional spectrophotometric method such as high selectivity because with the reaction time the evolution of the absorbance is measured, low detection limit (9), simplicity and rapidly (10) due to avoiding some experimental steps such as extraction or filtration. Several kinetic methods have been reported for the determination of different pharmaceuticals in drugs (11)(12)(13)(14).…”

Simple, cheap, sensitive, and accurate kinetic- spectrophotometric method has been developed for the determination of naringenin in pure and supplements formulations. The method is based on the formation of Prussian blue. The product dye exhibits a maximum absorbance at 707 nm. The calibration graph of naringenin was linear over the range 0.3 to 10 µg ml-1 for the fixed time method (at 15 min) with a correlation coefficient (r) and percentage linearity (r2%) were of 0.9995 and 99.90 %, respectively, while the limit of detection LOD was 0.041 µg ml-1. The method was successfully applied for the determination of naringenin in supplements with satisfactory results.

Flow analysis changed significantly the way of performing chemical analysis by (i) mechanization of analytical procedures in a continuous flowing stream with minimal sample intercontamination; (ii) analytical measurements without attaining chemical equilibria, thus increasing the applicability of kinetic methods and allowing the exploitation of non-quantitative processes; (iii) exploitation of concentration gradients and (iv) use of unstable reagents or measurement of unstable products. Flow-based procedures are generally characterized by high sample throughput, improved precision, minimized waste generation, and often better selectivity. The performance of detection systems is usually improved because of the in-line sample conditioning and measurements under reproductive dynamic conditions and timing. However, after achieving several innovations, perspectives for further developments have been questioned mainly because of the recent decrease in the number of publications on flow analysis. The aim of this review is then to discuss the impact of flow-based methods on chemical analysis, emphasizing recent applications and developments, including miniaturization, bioanalysis, microextractions, green analytical chemistry and synergic hyphenation with other techniques and processes. The author's personal view about research perspectives in the field is also presented.

“…The most accessible and fairly accurate method (method) for determining the intensity and distribution over the coordinates of the space of the function of internal losses from the action of induced currents (which is especially important when eddy currents are operating) is the thermometric method [1][2][3][4]. This method also makes it possible to determine the magnetic field strength on the surface of the electro-and magnetically conducting mass under study.…”

In this article, based on the accumulated experience of determining the intensity of the internal loss function in the active nodes of electromechanical devices, an experimental and analytical method for determining this intensity in time by the coordinates of the area under study is proposed. The error in determining the intensity of internal losses is determined based on comparing the results of calculating the integration of two variants of the two-dimensional heat equation.
